  • Patent number: 9933807
    Abstract: An in-rush current controller to turn-on a semiconductor output switch is described. The output switch is arranged in series with an output capacitor. The switch comprises a switch control port for controlling an output current and an output voltage. The controller comprises an amplifier to source or sink a switch control current to or from the switch control port, wherein the switch control current is dependent on an amplifier control current at an amplifier control port. The controller comprises a reference current source to provide a reference current at the amplifier control port, subject to a control signal indicating that the output switch is to be turned on. Furthermore, the controller comprises a feedback capacitor to provide a feedback current at the amplifier control port in dependence of a variation of the output voltage.

  • Publication number: 20060130754
    Abstract: A bowling lane conditioning machine is disclosed with circuitry that is operative to perform one or more of the following: dynamically updating a graphical representation of a lane dressing fluid pattern and/or zone, displaying confirmation that a selected component completed a desired function, displaying a log of activity, changing a language of text displayed on a display device, and displaying a graphical user interface with different menu options displayed differently. Also disclosed is a bowling lane conditioning machine with a display device located on a housing and an input device located on a handle, and/or with a first input device located on a handle and a second input device located on a housing. Further disclosed is bowling lane conditioning machine with two processors that operate independently from one another: one that controls a lane dressing fluid application system, and the other that provides a graphic user interface.
