1. A chip, comprising:
- one or more transmit circuits to provide a unique signal to a group of transmit sense lines embedded in a textile; and
one or more receiver circuits to identify one or more unique signals provided to one or more receive sense lines embedded in the textile to detect an object on the textile, wherein the transmit and receive lines cross over each other to form cross-over points and wherein the location of the object may be determined based on its position relative to one or more of the cross-over points.

Abstract
Some embodiments disclosed herein provide novel approaches for rapidly sensing sense line cross-point interaction in a textile such as a carpet or rug. A textile may comprise transmit and receive sense lines configured so that when an object contacts the textile and depresses one or more transmit lines against one or more receive lines, the object may be detected by monitoring unique signals produced by the transmit sense lines into the receive sense lines to detect the object.

7. A method, comprising:
-
applying a uniquely identifiable signal to each transmit sense line in a group of transmit sense lines embedded in a textile; and monitoring one or more receive sense lines embedded in the textile to determine if one or more of the transmit sense lines is in contact with the one or more receive sense lines, wherein said monitoring includes looking for the uniquely identifiable signals. - View Dependent Claims (8, 9, 10, 11)
