Title: Processor chip
Inventor: OMURA JIMMY K
IPC: G06F7/72
Filed: 1991-04-08
Granted: 2000-09-19
Abstract: A processor chip for adding a first integer having a plurality of groups of bits to a second integer having a plurality of groups of bits modulo a fourth integer having n-bits. The first integer plus the second integer equals a third integer. The processor chip includes a first register for storing the first integer, a second register for storing the second integer, and feedback register for storing a feedback number. The feedback number is the two's complement of the fourth integer. A plurality a full adders is coupled to the first register and the second register, and adds each group of bits of the first integer to the corresponding group of bits of the second integer, to generate the third integer. The bits of each group are added asynchronously during a time period.   Sequentially, a second group of bits of the first integer are added to the corresponding second group of bits of the second integer. The processor chip also multiplies the first integer by the second integer wherein the full adders sequentially add each group of bits of the second integer to each corresponding group of bits of the third integer, in response to the least significant bit position of the first integer shifted right from the first register. The processor chip can exponentiate a first integer having n-bits by a second integer having m-bits, wherein the first integer raised to the power of the second integer equals a third integer. The exponentiation is preformed with successive applications of the multiplication operation.

A  minimum "0"-path or minimum "1"-path respectively, and the assigned overall probability parameters are formed by means of the bit sequences of all the 2n' possible "0"-paths or "1"-paths respectively, having the smallest probability parameter. The binary value which is assigned to the smaller of the two considered overall probability parameters has an estimate ~ for the bit b i-n' and reliability information P(~) for this estimate ~ is formed on the basis of the two considered overall probability parameters.

Title: Self-serve checkout system
Inventor: SCHNEIDER HOWARD
IPC: G07G1/00
Filed: 1992-01-30
Granted: 1998-12-08
Abstract: A self-serve checkout system which consists of a self-service checkout station containing a video camera unit which generally views a first scale where bar coded products are deposited and which pivots to view a second scale where products without bar coded labels are initially deposited. The video camera generates a signal received by a display in a supervisor station which allows a supervisory employee to approve non-bar coded products and to survey in general other products deposited on the first scale. A plurality of self-service checkout stations are selectively connected to a singular supervisor station by a switching unit. The self-service checkout stations contain angled or active surfaces to prevent deposition of articles for later fraudulent removal. The self-service checkout stations contain receipt printers, magnetic payment card readers and coupon acceptors to further reduce the time the supervisory employee must spend on each order.

Title: Momentum wheel platform steering system and method
Inventor: BENDER DOUGLAS J
IPC: B64G1/28
Filed: 1992-04-22
Granted: 1997-08-19
Abstract: Method and apparatus for controlling the two-axis rate and position as well as the linear elevation of a momentum wheel platform supported by three jackscrews driven by stepper motors. By tilting the momentum wheel, a control torque is produced in the plane orthogonal to the nominal wheel spin axis. When all three actuators are operational, the control transformations are made unique by constraining the sum of the actuator extensions to be zero. When one actuator has failed, the above constraint is eliminated and the failed actuator is constrained to its measured value. Momentum wheel platform rotational rate commands generated by the roll/yaw control system are first integrated to give desired gimbal angles, and then transformed into jackscrew extensions. Jackscrew step commands are computed as the difference between these desired extensions and the current positions of the jackscrews. The position of each jackscrew is maintained by accumulating the step commands. The desired extensions are also back-transformed to compute gimbal angles that are fed back to the roll-yaw state control system. In ground command stepping, the momentum wheel platform steering method operates exactly as described above, except that relative jackscrew step commands from a ground station are utilized instead of the step commands computed in the rate following configuration.
