Abstract: An electronic game apparatus having a central body from which rigid arms extend to remote switches. The arms are pivotally connected to the central body and the remote switches to allow the apparatus to be folded for storage in an upright, free-standing position. Each arm has as member a sequence of numbers by which the players can keep score.

Abstract: A board game which comprises a board on which objects can be placed by participating players. An electrically powered sensor/indicator device is mounted to the board, the device incorporating electronic logic circuitry and indicator elements connected to the logic circuitry. A plurality of triggering devices are electrically connected to the logic circuitry. The triggering devices are operable by players of the game and the logic circuitry is actuatable by the triggering devices to electrically operate the indicator elements to signify a player who has first operated one of the triggering devices.

Abstract: A suppressed carrier radio signaling system is described in which there is a servo loop utilizing balanced circuit techniques and using the carrier as the reference, in which a phase detector (or coherent demodulator) constantly senses the phase difference between the carrier source and the carrier component in the output signal to derive an error signal which is used to vary the amount of the carrier component toward zero.

Abstract: 1. A receiver for use in a PSK signal translation system comprising a voltage tunable local oscillator for continuously generating a reference frequency signal from which the suppressed carrier can be reconstructed, input signal means for an incoming PSK signal, means for adding said reference frequency signal to produce a synthesized carrier which is amplitude modulated by said incoming PSK signal, diode switch means for demodulating synthesized PSK amplitude modulated carrier for causing synchronous phase shifts of the PSK signal components of modulated synthetic carrier in response to the demodulated signals, to thereby provide a continuous unmodulated signal synthesizing the suppressed carrier of the incoming PSK signals; a servo loop, including said oscillator, said signal adding means and said phase shifting means, for locking said oscillator onto said synthesized carrier.
