  • Patent number: 10475608
    Abstract: A slidable magnetic switch for controlling the electronic functions of an appliance on the Jewish Sabbath is disclosed herein. A housing with an integrated magnetic slider is permanently attached to the appliance surface directly adjacent to and above its embedded magnetic sensor, whereupon the magnetic force of the extended slider opens the sensor's electrical circuit and disables various auxiliary electronic functions whose operation is prohibited on the Sabbath. The slider is pushed back inside the housing after the Sabbath ends, allowing the sensor's electrical circuit to return to its regularly closed position, enabling the appliance's electronic functions for normal weekday operation. A timer alarm switch mounted within the housing provides an audible reminder to manually activate the magnetic switch each week before the Sabbath begins, or alternatively, to automatically extract the slider from the housing before the Sabbath commences, and retract the slider into the housing after the Sabbath concludes.

  • Patent number: 10461585
    Abstract: When a portable electronic appliance is provided with two systems, a wireless power-feeding system and a wireless communication system, each system requires two power-receiving devices, a coil and an antenna, leading to a problem of increased electronic appliance size and cost. Wireless power feeding employs the resonance method and uses a resonance coil using the resonance method and a power-receiving coil that receives power from the resonance coil. At least one of the resonance coil and the power-receiving coil can also be used as an antenna for wireless communication. Thus, a power-receiving device that can be used for two systems, wireless power feeding and wireless communication, can be provided.

  • Patent number: 10439392
    Abstract: A serial acquisition of multiple power sources via one or more multiplexers which is circulated in many corridors of a multi-port system with a resonant engine. A controller manages multiplexer/switches connecting a first plurality of DC power sources and an auxiliary DC power source to a circulator. A multiplexer/switch revolves each source of power to inverters for DC-AC conversion. Reciprocity of power sharing and management of signal routing between input power sources can be performed to maintain discrete operation between the input/output power sources and individual power inverters for precise load power delivery. Regenerative power from a motor load can be directed to “recharge” an input power source. The resonant engine applied to each power source provides a constant conduit of energy during off-operation/cycles.

  • Patent number: 10395865
    Abstract: A remote-controlled switch cover assembly is described for converting an existing rocker switch into a remote-controlled switch. The remote-controlled switch cover assembly receives a wireless signal to actuate the standard rocker switch and, in response, activates an electric motor that causes a gear train to turn in a first direction. This causes a wiper to engage an under-surface of a tilt plate located above the standard rocker switch and, in response, an opposing end of the tit plate depresses the standard rocker switch.
