Abstract: A remote control device may be configured to be mounted over the toggle actuator of a light switch and to control a load control device via wireless communication. The remote control device may include a base portion and a rotating portion supported by the base portion so as to be rotatable about the base portion. The remote control device may include a control circuit and a wireless communication circuit. The control circuit may be operably coupled to the rotating portion and to the wireless communication circuit. The control circuit may be configured to translate a force applied to the rotating portion of the remote control device into a control signal and to cause the communication circuit to transmit the control signal to the load control device.

Abstract: The invention relates a system for determining a change in a room (1). The invention comprises in particular a self-teaching illuminating system which detects a presence of an individual in an illuminated area. The system comprises lighting means (2) which output light, control means (3) which control the luminous output from the lighting means (2), measuring means (4) which determine a luminous intensity, and an evaluation means (6) which evaluates the luminous intensity determined by the measuring means (4). The evaluation means (6) is designed to detect a change of an object/individual in the room (1), starting from a determined luminous intensity at at least one first time, at which the lighting means (2) outputs no light, and a luminous intensity at at least one second time, at which the lighting means (2) outputs light.

Abstract: A monitoring device includes a comparison unit and a clock control unit. The comparison unit is configured to compare a signal level of a transmission signal and a signal level of a monitoring signal that has received the transmission signal with each other at a timing synchronized with a clock signal. The clock control unit is configured to detect the signal level of the monitoring signal and synchronize the clock signal with a timing when the signal level of the monitoring signal changes.

Abstract: In order that a power supply device capable of identifying the type of a connected LED light output device and outputting voltage or current suitable therefor completely eliminates the need to provide an additional circuit for the type identification on the LED light output device side and requires only a power supply cable for the connection, in an unconnected state with the LED light output device, electrical continuity between a second terminal to be connected to the cathode of an LED and a ground is cut, and when a transition from the unconnected state to a connected state is made, the voltage of the second terminal is measured to, on the basis of the measured voltage, identify the type of the connected LED light output device with the electrical continuity between the second terminal and the ground kept cut.
