Abstract: A system, device and method for detecting an audible alarm are provided. In one embodiment, the method may include the steps of receiving an audio input, determining that the audio input has at least a threshold magnitude, determining that the audio input includes one or more a target frequencies, determining that the audio input is received for a minimum duration; and wirelessly transmitting a first notification. The transmission may be received at a second device that may transmit an alert notification to a remote device, which may be, for example, the user or remote emergency system.

Abstract: Performance testing of transmission signals to ensure quality and compliance with governmental regulations by limiting interference with intended signals, such as entertainment signals seen by viewers, while reducing the manpower required for testing and eliminating the need for communication between field units and sources of transmission in order to improve traditional performance testing, for example, in Cable Television (CTV) Systems or CATV (Community Antenna TeleVision) Systems, which testing not only has been time consuming but also has required partial disruption of service, and application of these concepts to other modes of information transmission.

Abstract: A self-calibrating measuring tool. The tool includes a housing having a base and a recess terminated by a precisely located flange with respect to the base. A linear movable member is mounted within the housing with a measurement arm attached to it. A transducer is connected to the member for providing a measurement indication.
