Abstract: The system integrates a CCTV system including one or more video source units into the structured cabling system (“SCS”) of a building or the like by combining video signals, control signals and power for each video source unit over a single multipair cable made up of plural unshielded twisted pairs (“UTP”) of insulated copper conductors, so that one twisted pair of the cable carries the video signals, one pair carries the control signals and one or two pairs carry the power. The system includes combiners and distributors which can interface with the SCS cable through standard modular, multi-pin plug and jack connectors.

Abstract: A coin-operated phonograph in which certain functions are remotely controlled. A transmitter is provided for transmitting a number of modulated carrier signals, including an up volume signal and a down volume signal. The phonograph carries a multi-channel receiver that is adapted for receiving the carrier signals transmitted by the transmitter. A detector is connected to the receiver for detecting the modulated carrier signals. An amplifier with gain control is provided and is controlled in accordance with receipt of the modulated carrier signals. A manually-operable volume control switch is carried by the phonograph and may be used instead of the transmitter to control the gain of the amplifier.

Abstract: A coin-operated phonograph is provided which includes a cathode ray tube for displaying information, such as title strip data, in alphanumeric form. The phonograph includes means for storing the information to be displayed in digital form. An optical character reader is used for entering the information into storage in the storage means. Means are responsive to the storage means for controlling the presentation of the information on the cathode ray tube.

Abstract: A solid-state sound effect generating system for selectively producing any one of a plurality of predetermined sound effects has a plurality of interchangeable plug-in printed circuit boards each having mounted thereon an electronic circuit capable of being actuated to produce an electrical output signal representative of a unique one of a group of desired sound effects, without the use of any prerecorded signals or recording medium. The circuit boards are plugged into a common control chassis which interconnects them with an audio power amplifier and loudspeaker arrangement and which further provides input terminals for external triggering signals.
