Abstract: A system for early detection of water leaks at particular locations in any water-dependent appliance and apparatus used in multi-dwelling facilities. A central control apparatus electrically interconnected with a plurality of circuits that enable water leaks to be accurately detected in a diversity of devices including air conditioners, compressor coils, hot water appliances, and pipes, and for communicating the severity of the water-related problem. A plurality of water sensors are incorporated into specially designed probes of the preferred embodiment of the present invention wherein water leaks may be accurately and reliably detected in a diversity of water-dependent appliances and devices. A specially designed fiber glass cloth functions as a probe for sensing water leaks via its built-in plurality of sensors constructed from a corresponding plurality of conductive wires enables the location and extent of a water leak to be ascertained.

Abstract: Program schedules together with other periodically updated information is displayed to subscribers through a cable television system. The information is derived from optical image recordings and electronically generated from digital circuitry for display in synchronized relation to audio and color signals. The optically derived and digitally generated video signals together with color control signals are combined in a video mixer to modulate the output of a cable television transmitter operating on any desired channel.

Abstract: Program schedule information recorded on film is converted into video signals by two video record players for transmission with audio signals through a selected channel to cable television subscribers. The film is incrementally advanced in reverse directions for alternate display of different information recorded on separate frames of the film under control of a sequence controller operating through relays to effect synchronized operation of the video and audio tape players.

Abstract: Television programs schedules and visual time information are displayed by projection of composite images from the frames of a film strip and slides respectively displaced in synchronism on a cyclic basis and unidirectionally advanced at the end of each regular program period under control of a timer. During film frame movement, other visual material may be projected from intermediate slides in synchronism with audio message signals.
