Abstract: A system for locating players on a field includes first and second directional scanning antennas located adjacent the field. A transponder carried by the players detects the radiation from each antenna and transmits timing signals. The timing signals are received at a central station and compared to reference timing signals synchronized with the scanning of the antennas to provide an indication of the angular position of each player from the scanning antenna locations. The actual field position of the players can then be computed. The system can also locate the position of a playing object, such as a ball.

Abstract: A system is provided with a directional antenna having first and second antenna patterns oriented around an antenna boresight direction. The antenna boresight is oriented in a direction corresponding to a play determinative line on a playing field. Signals are emitted firm a playing object, used as a ball and detect using the two antenna patterns. Comparison of the detected signals provides an output indication when the playing object crosses the play determinative line.

Abstract: A poker tournament is displayed to an audience using a tournament table having stations for receiving and scanning the image of each players down cards. The display can identify the down cards of the players to the audience without revealing the information to the other players so that the audience can fully observe the strategy of each player.

Abstract: A toy doll includes a doll body and an animating mechanism in the doll body. The doll body includes a head portion including a resiliently flexible mouth section, a longitudinally expandable and contractible torso portion, and right and left arms and legs. The animating mechanism is operative by manually depressing the mouth section to actuate the animating mechanism to reciprocally move the mouth section inwardly and outwardly to simulate a chewing activity, and it is thereafter operative by manipulating one of the arms to actuate the animating mechanism to longitudinally expand the torso portion to simulate a growing activity.

Abstract: Appendage operated toys in which a moveable appendage of a toy figure energizes a power train that extends through the figure for engagement with an accessory that is operable by the power train. The power train may be used to store energy by virtue of the movement of the appendage, with the energy being released by operation of another appendage.
