Patent number: 8300374Abstract: A semiconductor component that includes a current limit circuit and a method for limiting current in the semiconductor component. An input/output pin is connected to the gate of a transistor and a control resistor is connected between the gate of the transistor and its source. One terminal of the control resistor is connected to the input/output pin and the other terminal is connected to another input/output pin. A current source is connected to the input/output pin. A reference voltage is generated between the two input/output pins and compared with a drain-source voltage that is between one of the two input/output pins and another input/output pin. A control voltage is set in accordance with the comparison. The control voltage then controls the voltage on another of the pins that is not common to the reference voltage and to the drain-source voltage.Type: GrantFiled: November 12, 2008Date of Patent: October 30, 2012Assignee: Semiconductor Components Industries, LLCInventors: Thomas William Ciccone, Thomas Duffy, Bryan McCoy, Timothy Kaske, John Ciccone

Patent number: 4311310Abstract: The present invention provides an electronic maze game wherein the player attempts to direct a playing piece through a maze to a goal within the maze. The goal is suitably indicated by a flashing LED on the game board. The position of the goal within the maze changes in a pseudo-random manner. In the preferred embodiment, the object of the game is to score as many goals in the shortest possible time, without passing through any forbidden zone in the maze. The forbidden zone is indicated by a flashing LED of a different color than the goal LED, and periodically changes position within the maze in a pseudo-random manner.Type: GrantFiled: November 19, 1979Date of Patent: January 19, 1982Inventors: Scott Dankman, Richard C.
