1. A device for identifying an individual comprising:
- a non-uniplanar member; and
sensing means for sensing the pressure exerted at preselected locations on said non-uniplanar member when said non-uniplanar member is grasped by the individual'"'"'s hand.

Abstract
A system for identifying an individual includes a graspable member and a plurality of pressure sensors at preselected locations on the graspable member for developing a uniquely identifying signal or print indicative of the pressures exerted by an individual'"'"'s hand in grasping the graspable member. Additional structure is provided for storing a plurality of such pressure indicative signals and for comparing the stored signals against later acquired signals in order to verify the identity of an individual.

6. A system for verifying the identity of an individual, comprising:
-
a non-uniplanar member; an array of pressure sensing elements disposed at preselected locations on said non-uniplanar member and operable to sense the magnitude of pressures externally applied to said graspable member at said preselected locations; signal means coupled to said sensing elements for developing a signal indicative of the magnitudes and locations of the pressures exerted on said non-uniplanar member when said non-uniplanar member is grasped by the individual'"'"'s hand; storage means for storing a previously acquired signal indicative of the magnitude and location of pressures exerted by an individual'"'"'s hand in grasping a member similar or identical to said non-uniplanar member; and comparator means for comparing said signal against said previously acquired signal so as to provide a control effect when said signal and said previously acquired signal are substantially similar. - View Dependent Claims (7, 8, 9, 10, 11)

12. A method of identifying an individual comprising the steps of:
-

14. A system for identifying an individual comprising:
-
a graspable member; sensing means for sensing the pressures exerted at preselected locations on said graspable member when said graspable member is grasped by the individual'"'"'s hand, said sensing means being operable to develop a signal indicative of the magnitude and relative location of the pressures exerted at said preselected locations when said graspable member is grasped by the individual'"'"'s hand; storage means for storing said signal and for retrieving said signal for use subsequent to development of said signal by said sensing means; comparator means for retrieving said stored signal from said storage means, comparing said stored signal against a subsequently acquired signal developed by said sensing means, and for developing a control effect when said subsequently acquired signal substantially matches said stored signal; and user input means for receiving a prearranged input code uniquely associated with a particular individual and for retrieving from said storage means a particular one of said stored signals for comparison by said comparator means against a currently developed signal developed by said sensing means such that said control effect is developed if said currently developed signal matches said particular signal associated with the particular individual. - View Dependent Claims (15, 16, 17, 18, 19)

20. A method of identifying an individual comprising the steps of:
-
providing a graspable member; sensing the magnitudes and relative locations of pressures exerted on said graspable member by the individual'"'"'s hand when said graspable member is grasped by the individual; comparing said sensed magnitudes and relative locations of pressures exerted on said graspable member by the individual'"'"'s hand against a previously acquired reference; and providing a control effect when said sensed magnitudes and relative locations substantially match said previously acquired reference.
