Abstract
A person or object is infused with a signal. The infused signal has a phase relationship with the signals that are transmitted from and used by a touch sensor, controller or wearable. The phase relationship of the infused signal is used in order to increase the ability of receivers at or on the touch sensor, controller or wearable to measure and determine touch events, such as hover.
Claims20
A phase relationship system, comprising:
- a first plurality of antennas operably connected to a signal generator, wherein the signal generator is adapted to generate a plurality of signals, wherein at least one of the plurality of signals is generated having a first phase;
- a second plurality of antennas operably connected to a receiver, wherein the second plurality of antennas is adapted to receive at least one of the plurality of signals;
- an infusion electrode operably connected to the signal generator, wherein the infusion electrode is adapted to transmit a signal having a second phase that is in a predetermined phase relationship with respect to the at least one of the plurality of signals having a first phase, wherein the first phase and the second phase are different;
- and
- a signal processor adapted to process and determine measurements of received signals.

A method for determining touch events, comprising:
- generating a plurality of signals on a first plurality of antennas operably connected to a signal generator, wherein at least one of the plurality of signals is generated having a first phase;
- receiving at least one of the plurality of signals on at least one of a second plurality of antennas operably connected to a receiver, transmitting an infusion signal via an infusion electrode operably connected to the signal generator, wherein the infusion signal has a second phase that is in a predetermined phase relationship with respect to the at least one of the plurality of signals generated having a first phase, wherein the first phase and the second phase are different;
- and
- processing and determining measurements of received signals in order to determine a touch event.
