Abstract: Securing device rejoining for a mesh network of a wireless lighting control system is disclosed. A potential security weakness of a mesh network protocol is that a proprietary link key may be discovered by close, expert examination of a device, potentially facilitating the joining of a “rogue” device to the network. Requiring subsequent rejoins of any device that had previously joined the network to use a current randomly generated link key, rather than the proprietary link key, prevents rogue devices only having the proprietary link key from joining.

In an example implementation, a circuit includes at least a first flip-flop, a second flip-flop, and a level-sensitive latch connected in a signal path from the first flip-flop to the second flip-flop.

A level-sensitive latch control circuit is configured to prevent the hold time violation by providing a pulsed clock signal to a clock node of the one level-sensitive latch circuit.

Abstract: A controller included in a lighting control device causes a transmitter to transmit a dimming rate which is determined by schedule information stored in a storage when power saving is not instructed via a power saving instruction signal. When power saving is instructed via the power saving instruction signal, the controller calculates a dimming rate for causing a luminaire to emit light at a brightness lower than in the case of the dimming rate determined by the schedule information. When the calculated dimming rate is a dimming rate which causes the luminaire to emit light at a brightness lower than a predetermined dimming rate, the controller causes the transmitter to transmit the predetermined dimming rate.
