Appl. No.:

10/071604

International Classification:

G06F011/00

US Classification:

714/704000

Abstract:

A method and apparatus for improving communication throughout a network is disclosed. The network includes a module capable of transmitting messages in response to a change of state. Bit errors transmitted within network are detected and a detected bit error rate is calculated. A residual, i.e., undetected, error probability is determined in response to the detected bit error rate. Corrective action towards reducing the effects of the residual errors is taken, e.g., retransmission of messages, in response to the residual error probability exceeding a predetermined threshold.

International Classification:

G06F017/60

US Classification:

705/028000

Abstract:

An inventory control and communication system provides automated real-time control of stock levels and ordering in a timely manner so that optimal stock levels are maintained. An inventory sensor that includes a storage unit, or bin, for each stock item or inventory object. One or more transducers are associated with each storage unit to produce a mass/weight signal indicative of the weight of the stock items stored in or at the corresponding storage unit. The signals are transmitted to a computer associated with the inventory sensor, which determines the weight and the number of the inventory objects present in the bin and provides this data as part of the inventory data associated with the inventory object. The inventory data is provided to a host computer that maintains information about the inventory sensor location and the corresponding stock item, such as item weight and supplier information. Threshold values for the minimum and maximum quantity of each stock item are also maintained by the host computer. When the quantity of a stock item reaches the minimum threshold, the host comptuer is operative to send an order to the supplier to restore the stock item to the maximum quantity threshold, or otherwise indicates that a reorder is needed.

International Classification:

H01M 8/04
H01M 8/00

US Classification:

429023000, 429012000

Abstract:

A control circuit controls power generation by a power cell in a presence of fuel and oxidant through electrical control. The control circuit may be extended to an array of power cells or array of banks of power cells to configure the cells or banks in series-row and column combinations to generate power in a selectable manner. The controller may include basic power maintenance and control of the array of power cells, and high level control modules may provide unique power generation control to cause the array to cold start, output time-varying waveforms, output multiple DC voltages from a single source of energy, regulate voltage or current, and so forth. Because the power cells may be configured in vast arrays, power cells may be connected to a group of other power cells in the array and driven with a time-varying voltage or pulse to self-clean catalyst of contaminants.

International Classification:

G01M 1500

US Classification:

731172

Abstract:

A method of testing compression capabilities of multi-cylinder engines wh are cranked with electrically-energized starter motors. The cylinders are prevented from firing, and the engine is cranked by the starter motor. During the cranking period measurements are taken of the starter motor current. A comparison of the peak current and average current provides an indication of the compression capability of the engine.

US Classification:

375 40

Abstract:

Messages are transmitted on pairs of frequencies that are orthogonal, that is the frequencies have no least common denominator (are prime to each other). A message is transmitted on the first of the pair of frequencies and, simultaneously, its complement is transmitted on the second of said pair of frequencies. The message is then retransmitted on another pair of orthogonal frequencies. In the second transmission, the message is remapped, such that, adjacent bits in the first transmission are not adjacent in the second transmission and the same bit in the first transmission and the second transmission are not spaced 1/120th of a second apart. Information is collected on the data error rates at each receiver. This information is periodically transmitted to a central frequency controller which collects this error information and determines the error rates on the frequencies being used. A hill-climbing technique is used to choose pairs of frequencies having the lowest current data error rates.

International Classification:

US Classification:

364900

Abstract:

An improved programmable controller having the ability to use two different data bases while presenting to the outside world a uniform word size. The programmable controller includes pipeline processing and hardware solution of a user control program in a network node format. A memory management scheme is provided allowing for the direct addressability of one-half million words by utilization of a page register. The programmable controller can be incorporated into a network containing other programmable controllers. The programmable controller also incorporates a multi-task interrupt so that the processor can handle more than one job at any particular time. Input/output tasks are handled logically in the scan solving the user networks rather than being based upon a particular physical area of the controller memory.
