Abstract: A ranging system includes at least one beacon and a control module. The at least one beacon is configured to scan each segment in a plurality of segments of an arc with a narrow radio frequency (RF) beam and receive a response signal from an end user node in at least one segment. Each segment of the arc is scanned at a specified time interval. The control module is configured to communicate with the at least one beacon. The control module is further configured to calculate at least one of an angle-of-arrival (AOA) and a time-of-flight (TOF) of a response signal from the end user node to the beacon and generate an end user node location relative to a beacon location.

Abstract: An apparatus which facilitates the pocketing of documents in a pocket in a business machine like a sorter. As a document is to be pocketed, it is moved along a rib structure (located on a pusher plate) which has a decelerating portion thereon to decelerate the document and to move the document against a side member in the pocket as it approaches a stop member within the pocket to thereby minimize the noise created by the first few documents entering the pocket. A second rib structure positioned near the top edge of the pusher plate engages the leading edge of a document to direct the document against a side wall in the pocket to also minimize the noise mentioned.
