Abstract: This invention comprises an image and audio data processing device that comprises a transceiver to send and receive image and audio data over a network, a camera module which captures and processes image and/or audio data individually or in combination when a user activates the camera module, a camera module sensor which identifies a use operation of capturing the image and audio data, and an indicator unit which includes a light emitting module. When the camera module is capturing and processing the image and audio data and the transceiver sends and receives said data over the network, the camera module sensor identifies the use operation and activates the indicator unit thereby illuminating the light emitting module.

Abstract: An apparatus for preventing freezing of interior water pipes. A thermal switch is attached to a hot and/or cold water supply pipe in a remote location that is prone to freezing in cold weather. The thermal switch electrically communicates with a power source and with a solenoid-actuated valve. The solenoid-actuated valve is located in a conduit communicating the outlet of the water pipe adjacent a water usage station with the water outlet of a fixture located at the water usage station. This conduit is separate from the existing supply line communicating the outlet of the water pipe with the fixture and does not, therefore, interfere with the normal operation of the fixture.
