Title: System and method for increased sheet timing operation window for registration
Inventor: DOBBERTIN MICHAEL T
IPC: G03G15/00
Filed: 2001-10-12
Abstract: An apparatus and method for moving a receiver into a registered relationship with a moving image-bearing member in a registration mechanism. The apparatus and method account for receivers that arrive at the registration mechanism outside a normal operating time window. When a receiver arrives too late, the receiver is accelerated to a speed greater than that of the moving image-bearing member for a period of time sufficient to account for the arrival delay. The receiver is then decelerated to a speed substantially equal to that of the image-bearing member. When a receiver arrives too early, the receiver is brought to a stop for a period of time sufficient to account for the early arrival. The receiver is then accelerated to the image-bearing member speed.

Title: Object identification system with adaptive transceivers and method of operation
Inventor: PICARD PAUL A
IPC: H01Q5/35
Filed: 1999-12-01
Abstract: An object identification system (100) includes a monitor (124) and a plurality of transceivers (114) that communicate over a common medium. The monitor includes a first transmitter (2424), a first receiver (2416), and a processor (2402). Each transceiver includes a resonant circuit (204), a transmitter (210), a receiver (208), and an antenna (202) coupled to the resonant circuit. The processor performs a method for performing transceiver communication (500) that includes the steps of: (a) transmitting (604) from the first transmitter a first frequency (170) for a first duration; (b) after lapse of the first duration, receiving (608) via the first receiver a response signal ( 172) from at least one of the resonant circuits;  (c) determining (510) a second frequency from the received response signal; and (d) performing (512) transceiver communication using the second frequency. Transceivers of the type having a resonant circuit coupled to an antenna, when operating in close proximity to each other, may interfere with the response from a single transceiver by absorbing the energy intended to be received by the transceiver, absorbing the energy transmitted by the transceiver, or altering the resonant frequency of the resonant circuit. By determining the second frequency for transceiver communication, the monitor may establish communication with the single transceiver at a frequency better suited for transferring operative power (1593, 1597) to the transceiver, conducting an interrogation protocol (912, 1140, 1130) for identifying the transceiver, or for data transfer (914, 916, 918, 920).
