Classification: CPC G | IPC G

Claim 0:
1. A touch sensor device (TSD) comprising:
a first electrode implemented in a first object;
a second electrode implemented in a second object that is different than the first object;
a drive-sense circuit (DSC) operably coupled via a single line to a coupling of the first electrode and the second electrode, wherein, when enabled, the DSC configured to:
generate a signal based on a reference signal;
provide the signal via the single line to the coupling of the first electrode and the second electrode and simultaneously to sense the signal via the single line, wherein sensing of the signal includes detection of at least one of a first electrical characteristic of the first electrode or a second electrical characteristic of the second electrode; and
generate a digital signal representative of the at least one of the first electrical characteristic of the first electrode or the second electrical characteristic of the second electrode.
