The Universal Power Strip is the similar to a standard power strip but features multiple country plugs and two power cables which will be plugged into two different power outlets instead of one. By this method the Universal Power Strip will increase the electricity from 110-120V to 220-240V and power the 220-240V devices. Notably, residences in North America are pre-wired with a 220-240V circuit, and this device will allow full usage of the system.

  • Patent number: 9257828
    Abstract: An electronic appliance powered by a power supply unit connected to a mains type electricity network, and for connection to a transmission line having two conductor elements and to a terminal in order to transfer data between the line and the terminal. The appliance has a front-end component connected to the line via an isolating transformer. Also, various additional components are connected to an electrical ground of the appliance. A discharge component is connected to the conductor elements of the line and becomes conductive in the event of a voltage surge due to a lightning strike. This eliminates the surge by establishing a flow of current from the line to electrical ground. A capacitive and/or resistive type divider component is interposed between the discharge component and electrical ground in order to co-operate with the power supply unit and/or one or more additional components to constitute a divider bridge.

  • Patent number: 9094112
    Abstract: A signal generator generates an electrical signal that is sent to an amplifier, which increases the power of the signal using power from a power source. The amplified signal is fed to a sender transducer to generate ultrasonic waves that can be focused and sent to a receiver. The receiver transducer converts the ultrasonic waves back into electrical energy and stores it in an energy storage device, such as a battery, or uses the electrical energy to power a device. In this way, a device can be remotely charged or powered without having to be tethered to an electrical outlet.
