Abstract: Apparatus for detecting the presence of electrically conductive fluids, including urine and other body fluids such as exudate from wounds, includes a pair of spaced-apart electrodes covered by absorbent material, together with a housing containing a signaling device which produces a palpable vibration, a sound, a light, or a radio signal when fluid in the absorbent material provides a conductive path between the electrodes. Spring contacts on the housing provide reliable connections with the electrodes and also serve to attach the housing of the signaling device to structure supporting the absorbent material, and may also be used to attach the absorbent material to the housing in embodiments where the housing is otherwise supported. Disposable sensing pad material which is comfortably soft and flexible can be produced in indefinite lengths with moisture-previous outer layers and an inner layer of absorbent thermally-weldable material.

Abstract: Apparatus for detecting the presence of electrically conductive fluids, including urine and other body fluids such as exudate from wounds, includes spaced-apart electrodes (44, 46, 96, 98) covered by absorbent material (58, 106, 108, 126, 128), together with a housing (30, 86, 154) containing a signaling device (32, 152, 172, 175) which produces a palpable vibration, a sound, a light, or a radio signal when fluid in the absorbent material provides a conductive path between the electrodes. Spring contacts (50, 138, 146) on the housing provide reliable connections with the electrodes and also serve to attach the housing of the signaling device (32) to structure (12, 78) supporting the absorbent material, and may also be used to attach the absorbent material to the housing in embodiments where the housing is otherwise supported.

Abstract: Disclosed herein are two embodiments of an alarm and security system. The first is a stand alone alarm and security system which includes a control panel and at least one transceiver for sending and receiving a control signal and a base station. The control panel receives information about one or more desired conditions in one or more geographical areas and transmits the information to a base station via the transceiver. The base station receives the information from the control panel and transmits the appropriate control signals to the control panel. The second embodiment includes a communications panel including first transceiver for receiving information about one or more desired conditions in one or more geographical areas and for receiving a control signal and for transmitting the desired condition information and a control signal to a base station. Either embodiment accepts information from an existing panel via telephone line and transfers a full data message to the base station.
