Electrical conductor array
First Claim
1. A pressure pad comprising first and second arrays of substantially parallel electrical conductors which are superposed and biased towards a spaced apart position with the conductors of said first array transverse to the conductors of said second array, wherein at least one of said arrays is responsive to applied pressure on said array to deflect against said bias towards the other array, wherein at least said first array comprises a number of blocks of substantially parallel first conductors, a number of first and second common conductors, said first conductors of each block being electrically connected to respective first common conductors and, between pairs of said first conductors of each block, a respective second conductor, corresponding second conductors from each block being electrically connected to a respective second common conductor, and wherein said conductors of said arrays are adapted to be connected to processing means to enable the position of applied pressure to be determined.

Abstract
An electrical conductor array particularly for use in a pressure pad is described. The pressure pad comprises two electrical conductors arrays (3,5) of substantially parallel electrical conductors which are superposed and biased towards a spaced apart position with the conductors of one array transverse to the conductors of the other. One of the arrays (5) is responsive to applied pressure on the array to deflect against the bias towards the other array (3). At least one of the arrays (3,5) comprises a number of blocks of substantially parallel first conductors (12), the first conductors of each block being electrically connected to respective first common conductors (13); and, between pairs of first conductors (12) of each block, a respective second conductor (14), corresponding second conductors (14) from each block being electrically connected to a respective second common conductor (15).
