Movement monitor
First Claim
1. A movement monitor comprising:
- a rigid base member for supporting a moving object in which movement is being monitored,a transducer located between said moving object and said base member for detecting movement of said moving object, said transducer providing an output signal in response to forces applied thereto,a reaction means secured to the base member and arranged to extend over, and be held in contact with, the moving object such that upward movement by the moving object is restricted by said reaction means and movement by the moving object against said reaction means causes force to be applied to the transducer, andcircuit means for monitoring said output signal from the transducer, said circuit means arranged to provide an alarm when said output from the transducer corresponds to no movement from the object.

Abstract
This invention relates to a movement monitor that is suitable for detecting movement, and also provides an alarm should movement that is being monitored cease. The movement monitor is particularly suitable for use with humans or other living organisms where breathing movement is being monitored. In considering the use of the movement monitor on human infants, it is particularly useful for preventing death from Sudden Infant Death Syndrome. The movement monitor comprises a rigid base member for supporting the moving object which is being monitored, and is provided with a reaction means which is secured to the base member and arranged to extend over and be held in contact with the moving object. A transducer is placed between the rigid base member and the moving object such that when movement occurs, the reaction means causes force to be applied to the transducer. The use of the reaction means provides a more positive application of movement force to the transducer thereby providing a greater deal of reliability in detecting movement. The output from the transducer is connected to a circuit means which is arranged to provide an alarm should the output from the transducer sense no movement from the moving object.
