    摘要: A bowling center system includes a plurality of lane pair control systems each including a pinsetting device for each lane, a pinsetter control unit, a game control unit, a bowler input station and a pair of overhead display monitors. The game control unit is operable under the control of a game control program stored in a memory for automatically operating the pinsetter control units during game play to selectively set a sequence of pin patterns on the lane, which patterns may comprise any array of pins. The game control unit responsive to pin fall data received from the gamesetter generates scoring information which is displayed using video graphic displays on the overhead monitors. The game control program can be any one of a plurality of different game programs which may be downloaded to the memory from a memory associated with the manager's control terminal. According to the particular game program, the number of bowling frames the game may vary as well as the number of balls and pins utilized in each frame. The manager's control system provides accounting control over the bowling center system and is operable to override operation of a selected game control unit as necessary. A plurality of remote terminals are provided associated with selected ones of said lane pair control systems. Each remote terminal system includes a keyboard and a display monitor. The remote terminal operates under the control of the game control unit to allow a user thereof to enter requests for video displays. The video displays include, for example, ball trajectory displays which illustrate the path of the ball on the bowling lane, or dynamic displays, such as for training, generated by video source devices associated with the manager's control system.

    摘要: A priority encoder for receiving input request signals at a number of input request terminals and for providing an N-bit output binary code word indicating the binary identification number of the highest-priority, currently-active input request terminal. Each output bit of the output binary code word is provided from a respective logic circuit. Whenever any one of a first group of input request terminals, which are identified as having a logical TRUE value in a particular bit position of the N-bit output binary code word, is active, all of a second group of input request terminals, having a logical FALSE value for the particular bit position, are disabled. Sequential operation of the logic circuits for each output bit is obtained by successively delaying enablement of a logic circuit until high-order logic circuits have completed operation.

    摘要: An optical data read/write apparatus is disclosed for use in reading a rotating optical disc having at least one concentric reference track and circular data tracks thereon. The apparatus includes an optical head which includes separate tracking and data beams directed onto the disc. The optical head is supported on a carriage which is movable by a linear actuator for movement radially relative to the disc. A substantially continuously operable closed loop servosystem which includes the linear actuator causes the tracking beam to follow the reference track. The data beam is movable relative to the tracking beam and is moved so as to follow a selected data track. A plurality of concentric reference tracks may be included on the disc in which case the linear actuator is supported on a second carriage movable in the same direction as the carriage that supports the optical head. A stepper motor controls the position of the second carriage for coarse positioning of the tracking beam relative to a selected reference track. Reference tracks may be recorded at a frequency outside the frequency range used for recording data tracks to allow for easy discrimination between reference and data tracks.
