A microcontroller based multifunctional electronic switch using a detection circuit design to convert external control signal into message carrying sensing signal readable to the microcontroller. Based on a time length of sensing signal and a format of the sensing signal received in a preset instant period of time the microcontroller through the operation of its software program codes is able to recognize working modes chosen by the external control signal generated by user, and thereby selecting appropriate loops of subroutine for execution. The system and method of the present invention may simultaneously be applicable to detection circuit design using infrared ray sensor, electrostatic induction sensor, conduction based touch sensor or push button sensor for performing multifunctions such as controlling on/off switch performance, diming or speed control and delay timer management within the capacity of a single lighting load or an electrical appliance.

Various systems and method related to home automation systems are presented. A service robot system may be present that includes a service robot that autonomously moves within a structure to perform a household task. The service robot system may include a wireless communication interface, wherein the service robot system is configured to transmit, via the wireless communication interface, an indication of robot activity indicative of the service robot moving within the structure. Such a home automation system may also include a home security system that includes one or more motion sensors that detect motion within a structure. The home security system may be configured to distinguish intrusion activity (e.g., a burglar) from robot activity based at least in part on the indication of robot activity.

A faceplate remote control device may be attached to a wall-mounted mechanical light switch that has a toggle actuator. The faceplate remote control device may include a toggle indicator that detects operation of the toggle actuator of the mechanical switch. The toggle indicator may cause the generation of an indication of detected operation of the toggle actuator. The toggle indicator may comprise a sliding member that is configured to move with the toggle actuator. The toggle indicator may comprise an obstruction detection device that includes an infrared (IR) transmitter and an IR receiver. The faceplate remote control device may include a control circuit and a wireless communication circuit. The control circuit may be configured to cause the wireless communication circuit to transmit one or more messages in response to detecting operation of the toggle actuator of the mechanical switch.

An occupancy detection apparatus has a switch, a first antenna, a second antenna, a transmitter, and a motion detection circuit. The occupancy detection apparatus monitors for a first motion in a first region using the first antenna using a first motion detection parameter. When no first motion is sensed by the monitoring using the first antenna, the occupancy detection apparatus monitors for a second motion in a second region using the second antenna using a second motion detection parameter. When no second motion is sensed by monitoring using the second antenna, the occupancy detection apparatus designates a space, which encompasses the second region, as unoccupied. The first region and the second region overlap one another, and the first motion detection parameter is different from the second motion detection parameter.
