Abstract: A repeater system for wireless communications applications is, in one aspect, programmable and controllable in a manner that enables multi-user, multiband, and multi-protocol operation. The repeater system includes a repeater coupled to an inside antenna system and to an outside antenna system, either or both of which may be adaptive. Inside cellular phones are coupled via links (that may be cellular or non-cellular) to the repeater and to a control unit, which is itself connected by a link to the repeater. The repeater includes a repeater core coupled to a control component. The core is constructed from a number of modules, the selection of which determines the operation and functionality of the repeater core. Core modules, selectively enabled by a user, establish one or more of the following modes of operation: passive, single-frequency active (SFA), Up/Down Converter (UDC), Remote Wireless Modem (RWM), and Shared-Identity repeater operation.

Abstract: An electronic control circuit is provided for controlling the operation of pinball machine flippers. Each flipper is operated in response to the energization of a single solenoid coil in which the same winding is energized to place the flipper in an actuated position and to hold the flipper in the actuated position. When a flipper switch is activated, a full wave rectified voltage is applied to the solenoid coil to place the flipper in an actuated position. When the flipper has been sensed to be in the actuated position, only a partial phase controlled voltage is applied to the solenoid coil to hold the flipper in the actuated position until the flipper switch is deactivated.
