Abstract: A coin sorter for sorting coins of mixed diameters is set forth. The sorter includes a coin-driving member and a coin-guiding member. The lower surface of the coin-guiding member forms a plurality of exit channels for guiding coins of different diameters to different exit stations along the periphery of the coin-guiding member. The coin sorter includes a brake mechanism which permits stopping of the coin-driving member at high speeds such that an invalid coin is retained or for ensuring the correct amount of coins is sent to the coin-collecting receptacle. The coin sorter also includes an operator interface panel for easy operator inputs. Operator inputs allow the operator to adjust the movement of the coin-driving member after encountering a stop and for adjusting the amount of lubrication sent to the coin-guiding member.

Abstract: A coin wrapping system comprises (1) a coin wrapping mechanism forming loose coins into wrapped rolls of coins, (2) an operator interface panel, and (3) a controller coupling the operator interface panel to the coin wrapping mechanism. To provide the coin wrapping system with total flexibility in operation and other functions, the operator interface panel includes a display and a touch screen mounted over the display. The controller causes the display to display keys. The controller operably couples the touch screen to the displayed keys such that actuation of the touch screen at a position above one of the displayed keys causes the controller to perform a function associated with that displayed key. Preferably, the controller is operable, via the touch screen, in a plurality of modes including a basic operating mode, a memory recall mode, an adjustment for wrap quality mode, a diagnostics mode, and a programming mode. The basic operating mode preferably includes an error detection and recovery function.

Abstract: A coin sorting system comprises a coin sorter for sorting a plurality of coins, an operator interface panel, and a control unit coupling the operator interface panel to the coin sorter. The coin sorter includes a coin-driving member having a resilient surface and a stationary coin-guiding member having a coin-guiding surface opposing the resilient surface of the coin-driving member. The coin-guiding surface is positioned generally parallel to the resilient surface. The resilient surface of the coin-driving member is constructed and arranged to move the coins along the coin-guiding surface of the coin-guiding member. The coin-guiding surface forms a plurality of exit stations for selectively allowing exiting of the coins based upon their respective diameters. The operator interface panel includes a display unit and a touch screen mounted over the display unit. The display unit includes a plurality of display fields for displaying keys, coin sorter status, and sorted coin total.

Abstract: A driver alerting device plugs into a vehicle cigarette lighter and, after actuation of a reset button, triggers a flashing red warning light after a random time period. If the driver does not actuate the reset button within a predetermined time after the light begins flashing, a horn will beep.

Abstract: A luminous power supply apparatus for driving gas discharge devices and the like with relatively high frequency voltages including an output transformer having a primary winding and a secondary winding across which a device to be powered may be connected, transistorized switches connected to the primary winding for providing pulses of alternating polarity thereto when driving, a pulse width modulator for driving the switches at an RF frequency, and a controller for selecting the width of the drive pulses to control the power applied to the device to be powered. The output transformer is comprised of: a pair of U-shaped core members having their corresponding ends joined together to form a unitary core; a primary winding wound about one side of the core and overlying a first junction of the pair of core members; a secondary winding wound about an opposite side of the core and overlying a second junction of the pair of core members; and potting means having a coefficient of resistance of 3.

Abstract: An intrusion alarm system for use such as in homes including an ultrasonic motion detector having means for selectively actuating switch means for a light and a sound alarm. The circuit includes a transducer for emitting a beam of ultrasonic energy and a sensor for detecting the modulation of the ultrasonic energy by movement occurring in the beam. The sensor provides a signal in response to said modulation to turn-on an electric light, and to turn-on a sound alarm.

Abstract: A T.V. remote control system includes a wireless hand control and a control unit easily and quickly coupled to any television. The control unit contains a varactor tunable frequency converter to convert selected signals to an unused channel responsive to the application of respective tuning voltages. Channel sequencing is possible directly or by remote control in addition to skipping of unused channels.
