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.

Control system with occupancy sensing

In one aspect, a portable electronic device is provided for accessing a secured area to deliver a package therein. The portable electronic device includes a sensor configured to detect an indicium of the package and communication circuitry configured to communicate a message to a server computer associated with the package upon the sensor detecting the indicium. The communication circuitry is further configured to receive delivery information from the server computer, the delivery information including at least a location of the secured area. The portable electronic device further includes a processor operatively coupled to the sensor and the communication circuitry. The processor is configured to cause, via the communication circuitry, the movable barrier operator to open a movable barrier associated with the secured area.

System and method for facilitating access to a secured area

In one aspect, a remote server computer is provided for facilitating operation of movable barrier operator systems having imminent motion notification apparatuses. The remote server computer includes a processor, a memory, and a network interface for communicating state change commands to the movable barrier operator systems via a network. The remote server computer is configured to receive a confirmation indicating that a sensor check has been performed to test sensors of those systems. Upon receiving a state change request from a remote control associated with a movable barrier operator system, the processor may determine whether the confirmation has been received for that system, and if so, causes communication of an attended command signal that inhibits operation of an imminent motion notification apparatus of the movable barrier operator system. Otherwise, the remote server computer may communicate an unattended command signal.

A load control system comprises a load control device and a battery-powered occupancy sensor, which transmits a first wireless signal to the load control device in response to detecting the presence of an occupant in a space. The load control system further comprises a visual indicator for providing a visual indication when the magnitude of a battery voltage of a battery of the occupancy sensor has dropped below a predetermined low-battery voltage threshold. The occupancy sensor may comprise the visual indicator, such that the visual indicator is illuminated when the occupancy detects the presence of the occupant in the space and the magnitude of the battery voltage is less than the predetermined threshold. Alternatively, the load control device may comprise the visual indicator, such that the visual indicator is illuminated in response to receiving a second wireless signal, which is transmitting by the occupancy sensor when the magnitude of the battery voltage is less than the predetermined threshold.

Radio-frequency lighting control system with occupancy sensing

A load control system controls an electrical load provided in a space and comprises a load control device and a first occupancy sensor mounted to a movable structure (e.g., a door) and a second occupancy sensor mounted to a fixed surface (e.g., a wall or a ceiling). The load control device controls the load in response to the wireless control signals received from the occupancy sensors. The first occupancy sensor transmits an occupied wireless control signal to the load control device in response to detecting the movement of the movable structure. The second occupancy sensor transmits an occupied wireless control signal to the load control device in response to detecting the occupancy condition. The load control device turns on the load in response to receiving the occupied control signal from the first occupancy sensor, and turns off the load in response to receiving vacant control signals from both of 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 adjusts the intensity of the load to a first intensity in response to receiving the occupied control signal from at least one of the occupancy sensors, and adjusts the intensity of the load to a second intensity less than the first intensity (e.g., a non-off intensity) in response to receiving vacant control signals from both of the occupancy sensors.

A motor is configured to operate in one of at least two modes in response to determining that a power provided by a power supply for the motor crosses certain thresholds. For example, first and second windings apply a rotating force to a rotating armature of a single motor. The first and second windings are electrically coupled to first and second commutators, respectively, which transmit power to the first and second windings from a first and second power source, respectively. In other aspects, different power sources power the motor, and the motor operates at different speeds depending on the power source applied. For example, the change in power sources is effected in response to detecting a change in applied power past a threshold, thus effecting the motor's operation in a second, different speed. So configured, a single motor can reduce deployment of bulky and expensive add-on equipment.
