Inventor: TANCEVSKI LJUBISA
IPC: H04B10/556
Filed: 1999-11-01
Abstract: A system and method for filling voids between optical signals during switching in an optical telecommunications system. The optical switch includes a void filling and scheduling software program resident in memory and executable by a processor. The memory also includes the wavelength, position in time, duration for each void between previously scheduled optical data packets. As a new optical data packet arrives at the optical switch, the void filling and scheduling software program will calculate the available delay for each delay line as measured from the arrival time of the new optical signal and schedule the new optical signal within a particular void if (1) one of the available delays falls within the position in time of one of the voids and (2) if the duration of the new optical signal measured from the particular available delay fits within the duration of that void. If the new optical data packet will not fit within any of the existing voids, the void filling and scheduling software program will use a conventional scheduling routing to schedule the new optical data packet on an output fiber.

Title: Meat emulsion pump control system for meat encasing machine and method of use thereof
Inventor: SIMPSON MICHAEL S
IPC: A22C11/10
Filed: 1998-05-22
Abstract: A meat encasing machine has a looper horn (12), linking chain (24) and conveyor (14) which, prior to production, have home positions which are determined. A pulsed signal is generated as the looper horn (12) rotates and is transmitted to an amplifier (36) from an encoder (34) on the servo motor (32) for the looper horn (12) and the conveyor (14). The output pulse signal is then reduced in frequency so that it can be read by a PLC (40). The PLC (40) counts the pulses in the signal and can determine the relative position of the looper horn (12) based on the count and can therefore minimize the rotation of the looper horn (12) in the home position at the beginning of each new cycle. The meat encasing machine may also be controlled such that the linking chain (24), looper (12), and conveyor (14) have no direct mechanical or electrical interaction between each other. By driving the components with separate servo motors (26, 32), each can be precisely controlled in the desired ratios with respect to each other.
