DETAILED DESCRIPTION - FIG. 1 illustrates an embodiment of an occupancy sensing system in keeping with some inventive principles of this patent disclosure. The embodiment of FIG. 1 contains a computer workstation 10 and an occupancy sensor 12 organized to monitor an area 14 related to the pc workstation for a number of occupants. The occupancy sensor 12 generates an occupancy signal in response to monitoring the house. A connection sixteen between the occupancy sensor and the pc workstation allows the computer workstation 10 to process the occupancy sign and perform a number of energy administration functions in response to the occupancy sign. A computer workstation (or "computer" or "workstation") refers to a mix of enter, output, and computing hardware that can be utilized for work or leisure by an individual, and consists of desktop computers, notebook computers, terminals connected to networks, and many others. The computing hardware could embody a central processing unit (CPU) to execute program directions. The workstation could process the occupancy signal from the occupancy sensor with software that makes use of CPU cycles to carry out its functions. Processing the occupancy signal could also be performed as a low precedence course of on the CPU. Implementing the occupancy signal processing as a low precedence process could integrate nicely with other CPU processes because, if the workstation is in use and different greater priority course of are working, there isn't a concern that the low precedence occupancy signal processing is slowed down. However, if the occupancy sensor is checking for occupancy, then the workstation is unlikely to be in use, and free CPU cycles can be found. Moreover, processing the occupancy sign with workstation CPU cycles may allow the processing power of the occupancy sensor to be diminished, thereby reducing its value. The occupancy sensor 12 has a area of view 18 that allows it to watch the area 14 related to the pc workstation. The occupancy sensor 12 may be based on any appropriate sensing know-how resembling passive infrared (PIR), ultrasonic (U/S), audio, video, etc., or any mixture thereof. FIG. 2 illustrates another embodiment of an occupancy sensing system in accordance with some inventive principles of this patent disclosure. FIG. 3 illustrates another embodiment of an occupancy sensing system in line with some inventive rules of this patent disclosure. The embodiment of FIG. Three is similar to the embodiment of FIG. 1 but in the embodiment of FIG. 3, the workstation 24 consists of functionality 26 that enables a user to regulate a parameter of the occupancy sensor at the workstation. The adjustable parameter could include a time-out delay, sensitivity setting, and so on., for the occupancy sensor. The connection 32 could also be integral with the connection 16 that carries the occupancy signal, or it could also be a separate connection. FIG. Four illustrates one other embodiment of an occupancy sensing system based on some inventive rules of this patent disclosure. The embodiment of FIG. 4 is just like the embodiment of FIG. 2 but the embodiment of FIG. 4 contains load monitoring apparatus 34 that permits the workstation 36 to observe one or more loads by way of a connection 38 to the workstation. The load monitoring apparatus 34 could also be separate from, or integral with, power change 20, and allows the workstation to find out power, voltage and/or present levels, in addition to on/off standing and different parameters of an electrical load. FIG. 5 illustrates an embodiment of a pc workstation according to some inventive principles of this patent disclosure. The workstation 42 of FIG. 5 includes a display 44 and a CPU 46. An occupancy sensor 48 is mounted to the show to facilitate monitoring the area related to the workstation. The occupancy sensor forty eight could also be separate from, or integral with, the show 44, and could also be primarily based on any appropriate sensing know-how. The occupancy sensor forty eight generates an occupancy sign which is transmitted to the CPU forty six via a connection 50, which could also be implemented with any appropriate wired or wireless connection. FIG. 6 illustrates an exemplary embodiment of a pc workstation in accordance with some inventive principles of this patent disclosure. The workstation 54 is shown divided into hardware and software program components. As explained above, the operating system fifty six typically includes inside power management options 88 that can be configured to turn off various items of hardware to cut back energy consumption when the workstation shouldn't be getting used. The interior energy management options 88 constructed into the operating system work on the assumption that the workstation is not in use when no person inputs within the form of key presses or mouse movements have been acquired for a predetermined time frame. Basing energy administration choices on the amount of time without person inputs to the workstation, nevertheless, typically results in incorrect assumptions that result in gadgets being turned off and/or the workstation being locked down whereas the consumer remains to be present at the workstation. Furthermore, if the consumer does go away the workstation shortly after the last person input motion, the workstation may be left unattended, totally powered, and unsecured throughout all the time-out durations set for the various parts. The appliance software program fifty eight may embrace inside energy management performance 78 that makes choices in response to the precise presence or absence of a person at the workstation reasonably than assumptions primarily based on the period of time without consumer input actions. The interior energy management functionality 78 determines the state of an occupancy sign from an occupancy sensor 28 by a USB port 68 and uses this info to make choices on when to show off power to various items of hardware, place the workstation in a suspend, sleep or hibernate mode, and/or lock down the workstation and require the user to re-enter a password. Utilizing an occupancy sensor to regulate the inner energy management capabilities of a workstation might scale back power consumption and/or enhance workstation safety. For example, occupancy sensors that use ultrasonic sensing expertise are inclined to have good sensitivity to the "small motions" that are typical of an individual working at a desktop, and due to this fact, could provide an correct indication of the presence of an occupant at a workstation. Due to this fact, the timeout delay for the occupancy sensor 28 could also be set to a comparatively quick period of time, e.g., a couple of minutes, without producing false indications of an unoccupied condition on the workstation. This may end in decreased energy consumption and improved safety as a result of the display, arduous drive and other hardware may be turned off and the workstation locked down shortly after the user leaves the workstation. Moreover, the usage of an occupancy sensor to control the internal power administration capabilities of a workstation might scale back or remove situations during which hardware is turned off and/or the workstation locked down despite the fact that the user is still current on the workstation. The appliance software program fifty eight can also include software to interface the workstation to a lighting control system or different building automation system by the network interface card 76 or by means of some other suitable interface. The person interface software 80 may additionally allow a consumer to configure which inside and external power administration actions to take in response to the occupancy sensor 28 akin to turning off the display 62 or hard drive 64, putting the workstation in a low power mode akin to sleep, suspend, hibernate, and so forth., locking down the workstation with password safety, turning off switched receptacles in a number of energy strips 89 and 90, turning off exterior tools with in-built power management capability equivalent to printer 92, or communicating with a lighting management system or different constructing automation system via the community interface card. The person interface can also enable the person to configure the applying software to show off inside or external hardware immediately upon receiving an unoccupied indication from the occupancy sensor, or after a number of further time delays. Varied further time delays may be used to stagger the occasions at which different pieces of hardware are turned off, as well as when they're turned again on to forestall excessive power surges when the presence of an individual at the workstation is detected again. The person interface may allow a person to process and/or view the ability consumption of the workstation and/or any peripherals having energy monitoring capability in real time, as well has historical data of power consumption to look for patterns that may present indications of how to achieve further power savings. The consumer interface may allow the consumer to configure the system to report energy consumption knowledge to a lighting management system or different constructing automation system for additional processing and analysis. The applying software may be applied with an application programming interface (API), thereby enabling it to hook, and be hooked by, different software. A few of the application software program functionality may be carried out with a user interface that's much like a typical screensaver, and one or more portions of the appliance software may be chosen from a display saver portion of the operating system. Nevertheless, the configuration and other hooks may be specific to the occupancy sensing and power switching units and their very own resident applications. The inventive principles aren't limited to instance implementation particulars shown in FIG. 6. For example, the connections made via the USB ports and NIC could also be implemented with wireless connections equivalent to Bluetooth, or could use alternative wired connections comparable to DisplayPort or HDMI connections. Power line communication (PLC) connections may be used to speak with power switches in energy strips or in switched receptacles situated in wiring gadgets near the workstation. Furthermore, switched energy receptacles could also be built-in instantly into the workstation to regulate energy to peripheral devices in response to an occupancy sensor that's connected to the workstation. FIG. 7 illustrates an embodiment of a dialog field for implementing a consumer interface in accordance with some inventive ideas of this patent disclosure. The dialog field 94 contains graphical "slider bars" for setting the sensitivity, area of protection (by way of viewing angle) and time-out delay for an occupancy sensor that's capable of receiving adjustable parameters. The dialog box also contains check packing containers to specify which internally controlled hardware comparable to displays (monitors) and onerous drives, in addition to which externally controlled hardware resembling energy strips, should be turned off in response to the occupancy sensor. FIG. Eight is a block diagram of an embodiment of an occupancy sensor based on some inventive rules of this patent disclosure. The occupancy sensor 96 includes a number of sensors 98 primarily based on any suitable sensing technology or applied sciences. A controller a hundred processes uncooked alerts from the one or more sensors 98 and generates an occupancy sign which is transmitted via a USB port 102. Conventional sensitivity and time-out delay controls 104 may be included to allow the controller to regulate the occupancy sensor for the specific space it's configured to watch. Alternatively, or additionally, the controller may adjust the occupancy sensor in response to adjustable parameters that it receives by way of the USB port 102. One or more indicators 106 could also be included to display the occupied/unoccupied status as decided by the occupancy sensor. For instance, a tri-shade LED could also be configured to display purple for an unoccupied condition, inexperienced for an occupied condition, and yellow for a fault situation. A "wake now" enter enables a consumer to take the system out of unoccupied mode if the sensor doesn't detect when the consumer returns to the workstation. Electronics in the occupancy sensor or utility software within the workstation might improve the sensitivity setting of the occupancy sensor each time the wake now button is pressed, since this may point out that the sensitivity setting is simply too low. FIG. 9 is a block diagram of an embodiment of a energy strip according to some inventive rules of this patent disclosure. The ability strip one hundred ten of FIG. 9 receives input energy from a connection 112 which may embrace a plug-and-cord assembly, connector prongs to plug straight into a receptacle, and so forth. A fundamental change and/or circuit breaker and/or surge arrestor 114 receives the input power which is distributed on to a first set of receptacles 116 which can be energized when the power switch 114 is closed. The workstation interface 130 allows the power strip to communicate with a workstation by a wired or wireless connection utilizing any appropriate interfacing association. The facility monitor circuit 128 may include any appropriate circuitry to monitor the voltage, present, power, and so on., of any load connected to any of the switched or unswitched receptacles. In some embodiments, a commercially obtainable meter chip could also be used along with a present sense transformer and voltage sense leads to provide a low-price answer which may be easily built-in into the power strip. The person interface 126 may include any type of inputs and/or outputs to enable a person to configure and/or management the power strip, enter parameters, verify the standing or performance historical past of the ability strip, and many others., from the facility strip itself. The user interface could embody one or more input units comparable to a potentiometer or different analog enter, digital switches of any kind including DIP switches, toggle switches, rotary switches, and many others. The person interface could embrace one or more output devices similar to lights, LEDs, numeric shows, alphanumeric displays, dot-matrix shows, etc. The consumer interface may be configured to enable a consumer to set one or more time delays that control the operation of the switching circuit as described under, as well as communication protocols, and/or additional time delay, and/or any other parameters. The communications with the workstation may be just one-manner to regulate a number of sets of switched receptacles, or bi-directional to allow reporting of power monitoring knowledge to the workstation. In some embodiments, the controller 124 in the power strip may be configured to turn each sets of switched receptacles one hundred twenty and 122 on or off at the same time as quickly as it receives a command from the workstation. In different embodiments, the controller could delay turning considered one of the two sets on or off to avoid energy fluctuations, surges, etc. Alternatively, the completely different units of switched receptacles one hundred twenty and 122 could also be managed by totally different commands from the workstation which can include logic for staggering load flip-on and turn off, or for controlling the 2 units of receptacles in another way in response to totally different occupancy situations at the workstation. For example, totally different hundreds may be turned on or off in response to completely different occupancy sensors in a multi-sensor association as described beneath. FIG. 10 is a perspective view of an instance embodiment of an occupancy sensor in accordance with some inventive rules of this patent disclosure. The embodiment of FIG. 10 could also be used, for example, to implement embodiment of FIG. 8. The occupancy sensor of FIG. 10 includes a compact housing 132 to facilitate simple mounting on a workstation show. The entrance of the housing contains two ultrasonic transducers 134 and 138 that are mounted on a convex floor to provide a defined coverage pattern (area of "view") for ultrasonic occupancy sensing. A mini USB port 140 enables using a standard USB cable to connect the occupancy sensor to a USB port on the workstation. A removable panel 142 conceals customary management dials for sensitivity and time-out delay settings. A pushbutton 144 could also be used to implement the "wake now" feature described above. In some embodiments, the coverage pattern of the occupancy sensor could also be adjusted by disabling one of many transducers, or by providing completely different weighting to the outputs from the transducers to implement a beam forming approach. The occupancy sensor of FIG. 10 could also be mounted in any appropriate location utilizing any suitable technique comparable to clips, magnets, two-sided tape, hook-and-loop fasteners reminiscent of Velcro, and many others. In some embodiments, a dedicated communication cable for connecting to a workstation could also be completely connected to the housing utilizing a pressure relief. Alternatively, or along with a USB port or everlasting cable, a wireless interface utilizing radio frequency (RF) or infrared (IR) know-how may be included for communication with the workstation. An Infrared Data Association (IrDA) suitable interface 148 is proven in FIG. 10 to implement IR communications. RF communication may be accomplished with an antenna that's inside to the housing if the housing is made from plastic. FIG. Eleven is a perspective view of an example embodiment of a energy strip according to some inventive rules of this patent disclosure. The embodiment of FIG. Eleven could also be used, for instance, to implement the embodiment of FIG. 9. The power strip of FIG. Eleven includes a housing 150, a plug-and-cord meeting 152, a predominant energy switch 154, an IrDA receiver 158, and a type-B USB port 156 for connecting the ability strip to a computer or different tools. Two sets of receptacles 160 and 162 are de-energized when the primary power switch 154 is within the OFF position. FIGS. 12 and 13 illustrate a aspect elevation view and a top plan view, respectively, of an example of the protection sample 164 that could be achieved with the occupancy sensor of FIG. 10. The occupancy sensor 131 is mounted to the top of a workstation display 166 that's situated on a desk 168. In this instance, the workstation CPU is included in the show 166 and is controlled by keyboard 170. As seen in FIGS. 12 and 13, the protection sample 164 includes the person's chair 172 and other areas associated with the workstation that the consumer is likely to occupy while actively working at the workstation. These areas embrace a printer 174, a task lamp 176 and a space heater 178. The protection pattern is typical of the pattern which may be achieved with a two-transducer ultrasound system. This sample may be altered by turning off or weighting the outputs from one or more of the transducers as described above, or by using other occupancy sensing applied sciences. FIG. 14 is a top plan view of a workspace associated with another embodiment of a workstation occupancy sensing system based on some inventive principles of this patent disclosure. The workspace of FIG. 14 is an office having a door 180, a desk 182, a chair 184 for the office's fundamental occupant, customer chairs 186, and a whiteboard 187. A workstation show 188 has two occupancy sensors 190 and 192 that are mounted on prime of the display and related to the workstation through USB cables or different varieties of connections as described above. The first occupancy sensor 190 has a coverage sample 194 that is generally supposed to incorporate only the house that is prone to be occupied by the principle occupant of the workplace while working alone. Both of the occupancy sensors 190 and 192 may be related to the workstation and configured and operated as described within the context of systems having a single occupancy sensor as described above, however with separate settings and actions defined for every occupancy sensor. For instance, room lighting or area heating in the workplace possibly turned on in response to either of the 2 occupancy sensors detecting an occupied situation, whereas the show, and any task lighting, printer, or different peripherals situated on the desk 182 might solely be controlled in response to the occupancy sensor 190 having the coverage sample 194 that includes the desk area. FIG. 15 illustrates one other embodiment of an occupancy sensing system in accordance with some inventive ideas of this patent disclosure. The embodiment of FIG. 15 consists of multiple workstations 200, each workstation having an occupancy sensor 202 related to the workstation using any of the techniques described above. Every workstation additionally has a minimum of one constructing light fixture 204 that illuminates the space associated with the corresponding workstation. The circulate of power to the constructing lights is managed by a load management machine 206 in response to commands acquired from a building automation server, workstation, or different controller 208. The load management machine 206 and building automation or lighting system controller 208 and workstations 200 are connected to a constructing community 210 by means of community adapters 212, 214 and 216, respectively, in addition to their very own particular person network interface playing cards. The building network 210 may be applied with Ethernet, CAN or other type of community appropriate for constructing automation, vitality management, and many others. The load control system could also be applied with a relay cabinet, dimmer rack, distributed relay/dimmer system, and so on., or another community connected load management device. The building automation controller 208 provides the overall operational logic for the system. When the controller 208 receives a message from one of many workstations indicating that the related occupancy sensor has detected an unoccupied situation for the associated space, it issues a command to the relay cabinet instructing it to turn off the light for the space related to that workstation. Upon receiving an indication from a workstation that the associated house is once once more occupied, the controller alerts the relay cabinet to revive power to the sunshine for that space. A possible benefit of the system illustrated in FIG. 15 is that it may enable lighting and other building automation programs to better accommodate occupants in cubicles or other comparatively small areas. Traditional lighting control techniques and other building automation methods usually employ ceiling or wall mounted occupancy sensors. Cubical spacing requires more densely placed sensors with correct alignment sophisticated by the situation of overhead lighting fixtures, heating ventilation and air conditioning (HVAC) tools, sprinklers, and so forth. Furthermore, the frequent rearrangement that's frequent with cubical areas presents a further challenge to proper alignment of occupancy sensors. The inventive rules relating to workstation-based occupancy sensor systems described in this patent disclosure, nonetheless, may scale back or get rid of these problems because the occupancy sensor for every workstation and its related workspace could also be positioned very easily in a close location that reliably displays the area most prone to be occupied by the workstation consumer. Moreover, the inventive principles may reduce the fee and uncertainty related to mounting numerous occupancy sensors on ceilings or partitions of buildings. In embodiments through which a workstation is networked to a lighting management system or other constructing automation system, the appliance software program may implement a blink warning override feature. For instance, the lighting management system could also be configured to turn off the lights in a constructing house in response to a timer-based vitality conservation schedule. In such a configuration, the lighting management system typically turns the lights off briefly (a "blink warning") prior to really turning off the lights to notify occupants of the impending automated turn-off. After the blink warning, the lights are held on long sufficient to allow occupants to leave the realm or input a request to the lighting control system to keep the lights on. Inputting a request usually requires the occupant to find a control station for the lighting management system. The closest control station may be a considerable distance from the occupant's workstation. Based on some inventive principles of this patent disclosure, the application software program could mechanically notify the lighting control system that the area associated with the workstation is occupied, and due to this fact, robotically override the blink warning for the light or lights that illuminate the space associated with the workstation. Alternatively, or in addition, the appliance software program may obtain a message from the lighting management system when a blink warning is imminent, and present a pop-up message or dialog field to the occupant advising the occupant of the impending blink warning. This may simply notify the occupant of the blink warning occasion, or the occupant could then be allowed to elect by the workstation to override the blink warning, or to permit the blink warning to proceed as normal. In embodiments in which a workstation is networked to a lighting control system or different building automation system, the appliance software may provide other override features. For example, if the lighting management system is configured to show off the lights in a building area in response to a timer-based mostly vitality conservation schedule, the applying software program may request that the lighting management system maintain the lighting within the space related to the workstation, no matter any blink warn functionality. The maintained lighting could embody not only the house related to the workstation, but in addition any associated areas to permit for egress from the space. The appliance software may also be configured to allow or override an attempt by a networked constructing automation system to sweep off energy receptacles in the space related to the workstation if the occupancy sensor signifies that the space is occupied. The sweep-off performance may be built-in with, or separate from the blink warning override performance. In embodiments during which a workstation is networked to a lighting control system or other constructing automation system, the application software program can also provide load monitoring data to the management or automation system if there's any load monitoring apparatus related to the workstation. This may increasingly allow the lighting management system or other building automation system to guage the effectiveness of the occupancy sensing and cargo management performance of the workstation-based occupancy sensing techniques, in addition to their interplay with other constructing automation methods. In places the place a handheld or other distant control is used for local control of lights in a lighting management system or different constructing automation system, a workstation having an occupancy sensor connected could also be further related to the distant management as a approach to interface the workstation to the management or automation system. For instance, an present handheld remote control could present on/off and dimming control of overhead lights through an IR receiver in a digital wall change or photocell machine. An extra wired or wireless connection may be created between the handheld remote and the workstation to allow the workstation to regulate the lighting in response to the occupancy sensor by the handheld distant, thereby eliminating the necessity for a network connection between the workstation and the lighting control system or constructing automation system. Alternatively, a wireless connection could also be created instantly between the workstation and the receiver that is used by the handheld distant, thereby allowing the workstation to speak instantly with the lighting management system via the existing system components and with out the need for an extra network connection. The strategies and apparatus described above allow the implementation of numerous options in line with the inventive principles of this patent disclosure. Some example implementation particulars are described beneath to illustrate the numerous options and benefits that may be realized. The inventive ideas, nevertheless, usually are not restricted to those example particulars. Though any appropriate occupancy sensing know-how, or combination thereof, could also be utilized, ultrasonic sensing may be notably well suited to the small areas and small movement that may must be detected for occupants performing office work in a cubicle. Mounting the one or more occupancy sensors on a workstation display might provide ultimate converge because workstation customers typically arrange their whole workspace across the show. Using an occupancy sensor that generates a standard occupancy signal that provides a binary occupied/unoccupied indication could simplify implementation and allow the use of current occupancy sensing circuitry which has been subjected to intensive troubleshooting, effective tuning and price reduction. Nevertheless, different varieties of occupancy sensors that provide extra uncooked output such because the unprocessed output from an ultrasound transducer or infrared pyrometer may be used, and the computing energy of the workstation may be used to process the uncooked output to make the occupied/unoccupied dedication. The occupancy sensors may embody onboard electronics which are solely sufficient to regulate the sensitivity and time-out delay primarily based on native inputs on the occupancy sensor, or the electronics could also be ready to regulate the occupancy sensor in response to adjustable parameters that are enter by a workstation consumer via a pop-up or control panel and transmitted via a USB or different wired or wireless connection. Power strips having a number of switched and unswitched power receptacles could present a super platform to change power to external workstation peripherals akin to process lighting, printers, area heaters, and many others., in response to an occupancy sensor coupled to the workstation. Nonetheless, different energy switching platforms may be used including single-receptacle plug-in modules that plug straight right into a wall outlet with out a energy cord and communicate with the workstation by a wired or wireless connection corresponding to a Bluetooth wireless interface. Other examples include building wiring devices corresponding to wall outlets which have switched receptacles and talk with the workstation by means of a wired or wireless connection. One sort of energy strip could embody a USB connection to the workstation with a mixture of switched and unswitched receptacles as shown in FIGS. 9 and 11. Another sort of receptacle may not have a connection to the workstation, but as a substitute may be linked directly to the occupancy sensor by way of a wired or wireless connection. Such an embodiment could have built in sensitivity and time-out delay functionality and may include person inputs to adjust these parameters. In embodiments during which a workstation may be positioned in a standby or hibernate mode when the house associated with the workstation is unoccupied, the facility for the USB or different connection to the occupancy sensor could also be turned off. Subsequently, the workstation operating system could must be configured to wake when it receives a sign on the USB or different connection. The inventive principles of this patent disclosure have been described above with reference to some specific instance embodiments, however these embodiments will be modified in arrangement and element without departing from the inventive concepts. For example, a number of the embodiments described above are illustrated in the context of lighting management methods, but the inventive principles may be applied to HVAC methods, security programs, and many others. As an extra instance, much of the performance within the embodiments described above is described within the context of a software implementation, but any of the functionality could also be applied with analog and/or digital hardware, software program, firmware, or any suitable combination thereof. Such modifications and modifications are thought-about to fall within the scope of the next claims.
