An occupancy sensor is an indoor motion detecting device used to detect the presence of a person to automatically control lights or temperature or ventilation systems. The sensors use infrared, ultrasonic, microwave, or other technology. The term encompasses devices as different as PIR sensors, hotel room keycard locks and smart meters. Occupancy sensors are typically used to save energy, provide automatic control, and comply with building codes.
Home automation system and method
InactiveUS6912429B1Matches need and abilityImprove automationSpace heating and ventilationTemperatue controlAutomatic controlEngineering
A home automation system and method for automatic control of controlled devices throughout a home. A unique architecture of occupancy sensors includes entry / exit sensors for detecting movement through doorways that separate rooms in the home, room motion sensors for detecting room occupancy, spot sensors to detect occupancy of specific locations within the rooms, and house status sensors to detect the status of certain parameters of the home. A central controller communicates with the sensors and controlled objects over a communications network, where the sensors and controlled objects can be added to the system in a ‘plug and play’ manner. The central controller controls the controlled objects in response to the entry / exit sensors, room motion sensors, spot sensors and the house status sensors. This control is accomplished by assigning each room to one of a plurality of room occupancy states, and to one of a plurality of room modes for creating desired room atmospheres using the controlled objects, which both dictate how the controlled objects are controlled by the central controller. The room modes travel from room to room as the occupant moves throughout the home, and multiple occupants can be using different room modes as they move about the home. The controlled objects also have controlled object states, which are used by the central controller to control the controlled objects.

Radio-frequency lighting control system with occupancy sensing
ActiveUS8009042B2Electrical apparatusElectric light circuit arrangementWireless controlControl signal
A load control system controls an electrical load provided in a space and comprises a load control device and one or more occupancy sensors. The load control device controls the load in response to the wireless control signals received from the occupancy sensors. Each occupancy sensor transmits an occupied control signal to the load control device in response to detecting an occupancy condition in the space and a vacant control signal to the load control device in response to detecting a vacancy condition. The load control device turns on the load in response to receiving the occupied control signal from at least one of the occupancy sensors, and turns off the load in response to receiving vacant control signals from both of the occupancy sensors. The load control device is operable to determine that no wireless control signals have been received from the occupancy sensors for the length of a predetermined timeout period and to subsequently turn off the load.

A control system for managing a heating, ventilating and air conditioning (HVAC) system based on occupancy of an area is provided. The occupancy may be determined by anticipated programming based on time of day zoning, and / or by actual sensed occupancy. In the later, the control system includes an occupancy sensor that communicates with a programmable thermostat. The occupancy sensor is disposed in the area and senses a state of occupancy of the area. The programmable thermostat instructs the HVAC system to adjust the temperature of the area within the structure based on the state of occupancy of that particular area to enhance occupant comfort and energy efficiency. The thermostat may also include programming modes or scripts that may be run to adjust operational control when abnormal occupancy conditions are sensed. Controllable dampers may also be used by the thermostat to achieve micro zoning control of the HVAC system.

An occupancy alarm system can be integrated into a motor vehicle or can be portable. The occupancy alarm system may be programmed to communicate with a program within a logic unit of the on-board computer within the vehicle or a cellular telephone or other wireless logic device so that if the driver's door is open and the engine is turned off but there still is an occupant in the motor vehicle, an alarm is immediately triggered. The GPS coordinates of the motor vehicle or the cellular telephone or other wireless device may be communicated to a remote location service or a local emergency center as part of the alarm. The occupancy sensor may be mounted on the occupant or on the restraint system, and may interact with an ambient temperature sensor and an alarm, both of which may be integrated into a motor vehicle, to indicate that a dangerous condition exists for an occupant within the motor vehicle. The occupancy sensor, the ambient temperature monitor, and the alarm may further be integrated together for a portable alarm system or may be mounted or otherwise integrated onto a portable restraint system. The occupancy alarm system may provide an interface and an override such that when the occupant remains in a potentially hazardous environment, that state is communicated via the interface and, if monitored by a responsible adult, the alarm can be overridden.
