  • Patent number: 9876390
    Abstract: When the preferred voltage source for a static transfer switch is a UPS, there can be a brief interruption in the voltage received from the UPS while the UPS is switching from economy mode to normal mode. Operation of the static transfer switch can be improved during such voltage disturbances. Specifically, the static transfer switch may be in data communication with the UPS and thereby made aware that the voltage disturbance is temporary. As a result, the static transfer switch can avoid an unnecessary transfer to an alternate voltage source.

  • Patent number: 9871298
    Abstract: A radio frequency (RF) energy harvesting device (rectenna) includes an antenna structure configured to resonate at RF frequencies, and a rectifying circuit that facilitates harvesting multiband RF signals having low energy levels (i.e., tens of mW and below) by utilizing two Zero Bias Schottky diodes having different forward voltage and peak inverse voltage values. Positive voltage pulses from a captured RF signal generated on a first antenna end point are passed by the first diode to a first internal node where they are summed with a second RF signal generated on the second antenna end point (i.e., after being passed through a capacitor), thereby producing a first intermediate voltage having a substantially higher voltage level. Positive voltage pulses are then passed from the first internal node through the second diode to an output control circuit for conversion into a usable DC output voltage.

  • Patent number: 9848477
    Abstract: The invention discloses a method for controlling the time sharing starting of electronic ballasts and a delayed-started electronic ballast. According to the method, the electronic ballasts are delayed-started after being energized, and delay time for the delayed starting of the electronic ballasts is a random number acquired based on the temperature of the ballasts. The delayed-started electronic ballast includes an electronic ballast body and a delay switch. After the adoption of the technical scheme of the invention, a delayer with the delay time set by virtue of random numbers corresponding to different environmental temperature is additionally arranged in the ballast, and multiple ballasts connected in parallel in a circuit can be started at different time points after different delay time under the control of the same control switch, which remarkably reduces current impact on a power grid and reduces a voltage drop condition.
