Abstract
Systems, apparatus, and methods measure a signal provided by a capacitance sensor, the signal indicative of a presence of an object proximate to the capacitance sensor. Responsive to measuring the signal, embodiments access control information in a memory to determine whether the signal is associated with a first qualifying event of the control information. Responsive to determining that the signal is associated with the first qualifying event, embodiments control a power consumption of a communication device.
