Abstract: An occupancy sensing system and/or an occupancy sensor including a transmitter arranged and configured to provide a verbal (i.e., audio) notification before changing a state of a load such as, for example, turning OFF a load (e.g., lights, etc.) coupled thereto. In some embodiments, at a predetermined period of time prior to changing the state of the load, the occupancy sensor emits a verbal notification to elicit feedback from any occupant who may be present in the monitored space. In response, the occupant may respond with a verbal confirmation and/or by moving. In some embodiments, the transmitter may be a speaker for transmitting a verbal notification. Alternatively, the transmitter may be a wireless transmitter for communicating with a remote device for relaying the verbal notification.

Abstract: A circuit interrupter device for selectively connecting a source of AC power from a line side to a load side of the circuit interrupter device includes a controller powered from a source of AC power from a line side. The controller initializes a self-test and determines whether the self-test was successful. The controller outputs a self-test result signal. An electrically-held relay of the device, which is in communication with the controller and is powered from the line side, stays in an OFF state until the self-test result signal indicates the self-test was successful, and enters an ON state if the self-test was successful. When in the OFF state, a load side of the circuit interrupter device is not in electrical communication with the source of AC power, and when in the ON state, the load side is in electrical communication with the source of AC power.

Abstract: Techniques for securely controlling multiple lighting devices simultaneously with a lighting control device are disclosed. Command messages may be transmitted from the lighting control device to multiple lighting devices over a computer network without routing through a remote cloud service. The messages may be encrypted and may include an incremented sequence number. Lighting devices that receive a command message may compare the incremented sequence number to a previously stored sequence number corresponding to the lighting control device. If the incremented sequence number is greater than the stored sequence number, then a lighting device may determine the message was transmitted by an authorized lighting control device and may implement any command instruction included therein. If the incremented sequence number is equal to or less than the stored sequence number, then the lighting device may determine the command message was transmitted by a malicious source and may ignore the command message.
