Abstract: A conveyor system for processing items on which radio frequency identification tags are disposed has a conveyor that conveys items through a path of travel, and an antenna disposed proximate the path of travel. Circuitry in communication with the antenna may associate RFID tag data with a package on the conveyor based on a difference signal from elements in the antenna.

Abstract: An antenna for use in a conveyor system in which items on which radio frequency identification tags are disposed are moved on a conveyor along a path of travel, includes a ground plane, a substrate having a bottom surface received adjacent the ground plane, at least one patch element disposed on a top surface of the substrate, a cover received adjacent the top surface of the substrate, and a front static conductive strip disposed along a front edge of the cover. The antenna is disposed beneath the conveyor and a front edge of the antenna is transverse to the path of travel. The front static conductive strip is electrically connected to the ground plane such that an electrostatic discharge event adjacent the front static conductive strip is discharged to the ground plane.

Abstract: A demodulator and demodulating system for use with a frequency shift key signal, and method of operation thereof. In one embodiment, the demodulator includes a receptor that is conf igured to receive a frequency shift key signal, and a discriminator coupled to the receptor that is conf igured to demodulate the frequency shift key signal by employing a Teager operator.
