Apparatus for object information detection and methods of using same

摘要

A system for determining information regarding at least one object, comprising: a sensor sensitive to capacitive coupling; at least one object adapted to create a capacitive coupling with the sensor when at least one signal is input to the sensor; a detector adapted to measure at least one output signal of said sensor associated with the at least one object, wherein the output signal associated with the at least one object is an object information code.

1. An apparatus capable of obtaining information regarding an object interacting with a capacitive based sensor of the apparatus, the apparatus comprising:
(a) a sensor section comprising:
a capacitive based sensor including a first and second set of electrodes that extend over a sensing surface and are capacitively coupled; andcircuitry configured to repeatedly scan at least a portion of the first set of electrodes and sample corresponding output from at least a portion of the second set of electrodes at a defined report rate during an active mode of the sensor section; (b) a host section configured to process information received from the sensor section for determining information regarding an object interacting with the sensor and to provide output of the processed information to a user operating the apparatus; and (c) a controller section providing an interface between the sensor section and the host section and configured to control operation of the sensor section; wherein the controller section is configured to switch operation of the sensor section from the active mode to a hibernation mode responsive to determining that no object is interacting with the capacitive based sensor.
