  • CIRCUIT FOR GENERATING A VOLTAGE WAVEFORM
    Publication number: 20160322960
    Abstract: A circuit for generating a voltage waveform at an output node. The circuit includes a voltage rail connected to the output node via a voltage rail switch; an anchor node connected to the output node via an inductor and a bidirectional switch, wherein the bidirectional switch includes two or more transistors connected in series; and a control unit configured to change the voltage at the output node by controlling the voltage rail switch and the bidirectional switch so that, if a load capacitance is connected to the output node, a resonant circuit is established between the inductor and the load capacitance. The circuit may be included in an apparatus for use in processing charged particles, e.g. for use in performing mass spectrometry or ion mobility spectrometry.

  • Safety Alert Device for Electric Stoves
    Publication number: 20160281995
    Abstract: A safety alert system that monitors the presence of electric current flowing into an electric cooking stove as to provide an alert or reminder to anyone in the vicinity that the stove is powered on. The alert system is composed of a stove power sensor that connects to the stove's power terminals and an alert device that plugs into a wall receptacle and has audible or visual alerts, the wherein the two are connected through radio frequency. When stove current is detected, the power sensor transmits a coded radio frequency signal to the alert device. The alert device produces an alert to indicate to anyone in the vicinity that the stove is on by an indicator. The alert device may indicate if the room light is turned off at night while the stove remains on and/or if the stove has been on for a long period of time.
