Abstract: A system for controlling a power input to a load includes a gate action monitor configured to transmit a door activation signal corresponding to an opening or closing of an access way to an enclosed space, a double signal sensor configured to transmit an occupancy signal corresponding to a detected occupancy of the enclosed space and a temperature signal corresponding to a detected temperature of the enclosed space, and a controlled load switch configured to detect one or more of the door activation signal, occupancy signal and temperature signal, and enable or disable the power input to the load.

Abstract: A sensor switch includes an infrared sensor, and a control unit coupled to the infrared sensor and configured to receive a signal corresponding to an object detected by the infrared sensor, wherein the control unit is configured to enable an ON state of a device under control of the sensor switch for a period of time depending on a duration and a strength of the signal from the infrared sensor.

Abstract: A safety door for use with a rotatable power supply socket having a mounting base with plugging holes therein. The safety door includes first, second and third sliding parts, and an elastic assembly. The safety door includes three rectangular plugging holes, a left-hand, middle and right-hand plugging hole, and two ground plugging holes, upper and lower. While sliding in a rail slot of the mounting base, the first sliding part can block the left-hand plugging hole while sliding along the left-right direction, the second sliding part can block the right-hand plugging hole while sliding along the left-right direction; the third sliding part can block or expose the middle plugging hole while sliding along the left-right direction. The elastic assembly includes a first elastic part for providing returning elastic force to the first sliding part and a second elastic part for providing returning elastic force to the second sliding part.

Abstract: The disclosed embodiments are directed to a protective shutter assembly that includes a registration member having longitudinal and lateral axes, first and second shutter members slidably mounted in the registration member, each shutter member including a ramp member and a receptacle blocking member, the ramp member being configured to lie in a path of a first receptacle opening and the receptacle blocking member being configured to lie in a path of a second receptacle opening, spring members connected between the registration member and respective ones of the first and second shutter members, the spring members being configured to bias the first and second shutter members so that the ramp members lie in a path of a respective receptacle opening, and wherein the first and second shutter members are independently movable such that when an object exerts a force on only one ramp member, a respective shutter member moves relative to the other shutter member such that the one ramp member is longitudinally displace

Abstract: A weatherproof outlet enclosure is provided for connections between a number of electrical outlets and various electric loads comprising: at least one rectangular slider plate for replacing existing receptacle face plate in a gentle sliding way; a base plate for mating with a predetermined number of the slider plates which lock into place by a single click stop, and a cover having a hinged attachment to one of the side walls of the base plate and a latching connection with an opposite location of the side walls from the hinged attachment, the cover in its a lower latched position enclosing the electrical outlets leaving passages for up to four cords leading from the electric loads connected.

Abstract: A safety door for a rotatable power supply socketincludes a mounting base with composite plugging holes, first, second and third sliding parts, and an elastic assembly. The composite plugging holes include a left-hand, middle and right-hand plugging hole, and an upper and lower ground plugging hole. While sliding in a rail slot of the mounting base, the first sliding part can block the left-hand plugging hole while sliding along the left-right direction, the second sliding part can block the right-hand plugging hole while sliding along the left-right direction; the third sliding part can block or expose the middle plugging hole while sliding along the left-right direction. The elastic assembly includes a first elastic part for providing returning elastic force to the first sliding part and a second elastic part for providing returning elastic force to the second sliding part.
