Hand pressure level threshold sensor
First Claim
1. A hand pressure sensor for use with a hand held implement useful for performing a task other than hand gripping pressure measurement, said sensor comprising:
- a hand held implement; and
a hand pressure sensor for outputting a first signal representative of the hand gripping pressure applied to said sensor, said sensor including first means for initiating said first signal when said hand gripping pressure applied to said sensor exceeds a first selected pressure level;
said sensor being coupled to said implement to be grasped as a person uses said implement.

Abstract
A hand pressure threshold sensor generates a signal representative of the application of excessive force to a hand held instrument to which the sensor is coupled. By using the sensor, a person having impaired tactile sensibilities, such that he is unaware of the degree of force he is applying, an instrument may be alerted that he is applying excess force. By reducing the force being applied to the implement, the person will avoid harming his hand or the implement as a result of his unknowing application of excessive force. The sensor may be provided with a threshold which outputs a signal representative of inadequate grasping force as well. A dedicated sensor may be incorporated directly within an implement, for example a fountain pen. A portable sensor may be utilized with a variety of hand held implements.
