Capacitance sensing devices and methods

摘要

A system can include an input for receiving objects having a flat shape; a capacitance sensing network comprising a plurality of capacitance sensors positioned to be proximate to the received objects; an operations section coupled to the capacitance sensing network and configured to perform predetermined operations on the objects; and a processor section coupled to receive capacitance sense values from the capacitance sensors and configured to determine the presence and features of received objects, prior to the objects being forwarded to the operations section.

1. A system, comprising:
an input for receiving objects having a flat shape; a capacitance sensing network comprising a plurality of capacitance sensors positioned to be proximate to the received objects; an operations section coupled to the capacitance sensing network and configured to perform operations on the objects; and a processor section coupled to receive capacitance sense values from the capacitance sensors and configured to determine a presence and features of received objects, prior to the objects being forwarded to the operations section; wherein the input comprises an input feed path configured to convey received objects over a distance to the operations section, and alter how such objects are conveyed in response to outputs from the capacitance sensing network.
