This invention relates to the design of sensors for detecting vibrations in collapsed structures. The sensor comprises a cube-shaped housing and a transducer attached internally between two opposite corners of the housing. The response of the sensor is fairly independent of which side of the housing is coupled to the collapsed structure and the sensor can also detect vibrations which occur in any signal axis of the structure.

Vibration sensing device

A Pole Alarm System including an electromagnetic field sensor and collision sensors for detecting overhead power lines and physical obstructions within the intended path of a telescoping mast or utility boom device is disclosed. The present alarm system includes a mast-mounted housing containing the sensors and a microprocessor-based control unit which interprets the output signals of the sensors and provides both audible and control feedback to a safety control module in the vehicle to alert the operator of impending contact and to automatically stop the movement of the mast. The alarm housing also features a light source which provides illumination in the direction of movement of the mast to assist in positioning thereof. The light source also functions as a heating element to prevent the accumulation of ice on the housing which would detrimentally affect the performance of the system. The alarm housing also includes a plurality of Tilt sensors which monitor the orientation of the mast to prevent mast extension if the device deviates from an acceptable range of operation. A system integrated safety control module mounted in the vehicle provides self-test functions and an error code display to alert the operator to the cause of an alarm signal.
