  • Patent number: 6435672
    Abstract: A method of increasing the reliability of an inkjet printer containing at least one pressure chamber provided with a nozzle for jetting ink drops therefrom and wherein when a disturbance in the pressure chamber is detected, the jetting of the ink drops is interrupted for a predetermined period of time. During this “waiting time” no active restoration operations are carried out, but rather the pressure chamber is left on its own to re-establish its normal operating condition prior to resuming the jetting of the ink drops from the nozzle.

  • Patent number: 6369344
    Abstract: A method of facing a substrate comprises applying a plurality of facing bodies to a carrier in a pattern corresponding to the desired pattern of the bodies on the faced substrate. The carrier has holes positioned centrally with respect to each body. Each body has, on a contact face to be fixed to the substrate, spaced raised weld elements which serve to locate the contact face parallel to and spaced from the substrate. The carrier is applied to the substrate with the contact faces of the bodies facing the substrate and then each body is electrically welded to the substrate by applying a welding tip to the body through each hole. A gap remains between the contact face and the substrate. Finally, the bodies are brazed to the substrate and brazing material flows between the bodies and the substrate. A facing kit comprises a carrier strip with facing bodies adhered thereto, each having raised weld elements in the form of dimples or lines.

  • Patent number: 6292762
    Abstract: A method determines a random permutation of input lines that produced a permuted set of bits in a bitstream. In a source design, the method replaces a logic element whose input lines are permutable with a test function. The source design is processed by a design tool to generate the bitstream including the permuted set of bits. The test function is probed with test values, and the probe results are compared with the permuted set of bits to discover the permutation of the set of bits. The test values can include a message.

  • Patent number: 6265092
    Abstract: A method of operating a H2—O2 fuel cell fueled by hydrogen-rich fuel stream containing CO. The CO content is reduced to acceptable levels by injecting oxygen into the fuel gas stream. The amount of oxygen injected is controlled in relation to the CO content of the fuel gas, by a control strategy that involves (a) determining the CO content of the fuel stream at a first injection rate, (b) increasing the O2 injection rate, (c) determining the CO content of the stream at the higher injection rate, (d) further increasing the O2 injection rate if the second measured CO content is lower than the first measured CO content or reducing the O2 injection rate if the second measured CO content is greater than the first measured CO content, and (e) repeating steps a-d as needed to optimize CO consumption and minimize H2 consumption.

  • Patent number: 6266002
    Abstract: A multi-bit DAC (109) is provided as part of a digital-to-analog data converter (DAC). The multi-bit DAC is comprised of a plurality of single-bit DACs (503) which have the values thereof selected through a digital encoder (505). The digital encoder (505) performs dynamic element matching (DEM) on an input data value. The sequence of selection is performed such that the element mismatch noise response of the DAC (109) is shaped. The outputs are summed at a summing junction (507) and then filtered with a low pass filter (113). In the noise shaping response, a cyclical second order response is provided with a Data Weighted Averaging (DWA) technique wherein the outputs of the DACs are restricted to one of two states. To achieve this, select ones of the output values are changed in order to comply with this restriction, thus deviating from a uniform element selection algorithm. This provides a constrained second order response which accounts for mismatching of the DAC elements (503).

  • Patent number: 6206188
    Abstract: A receptacle for the safe storage and disposal of used cutting blades, the receptacle being configured as a closed receptacle having an insert slot at opposite ends for the insertion of the used cutting blades into the receptacle. Each insert slot includes an angled guide for guiding the used cutting blade toward the insert slot. Interiorly, the angled guides act as detents inside the closed receptacle to inhibit the inadvertent dislodgement of the used cutting blade outwardly through the adjacent insert slot. The top wall of the receptacle is angled inwardly into the receptacle to serve as a deflector to prevent a used cutting blade from passing directly from one insert slot to the other insert slot. The receptacle is configured to be belt mounted or to be releasably secured to a toolbox, wall, or the like. The receptacle is also configured to be readily disposable when filled with used cutting blades.

  • Patent number: 6168718
    Abstract: A method for purifying conventionally treated blood plasma to remove substantially all residual leukocytes while maintaining useful flow rates for medically useful amounts of plasma utilizes a disposable, heat-sterilizable filter employing one or more depth-type prefilters and at least one intermediate hydrophilic microporous membrane followed by at least one final hydrophilic microporous membrane having a smaller pore size than the intermediate membrane within a common housing. The purified plasma is preferably subjected to chemical treatment to destroy infectious agents such as hepatitis and HIV.

  • Patent number: 6108734
    Abstract: In a relaxed bus protocol for transferring bursts of data from a slow device to another device, a predictor generates an advance signal. The advance signal is used to load next data into an output register of the slow device, the next data can then be transferred to the other device. A validator/corrector receiving a ready signal from the second device, the validator/corrector determines that the advance signal is correctly generated by the predictor. Heuristics and a higher level protocol adjust the size and frequency of the bursts of data to achieve optimal performance, and maintain correctness of transmitted data.

  • Patent number: 6080710
    Abstract: A process for making a coated bleach component which may be incorporated into a detergent composition comprising hydrogen peroxide solution. The process includes the steps of dispersing the bleach component in a continuous liquid phase to form discrete islands of dispersed phase and subsequently forming a polymeric coating at the interface between the dispersed phase and the continuous phase. The coating formed is resistant to hydrogen peroxide solution and is removable when the liquid continuous phase is diluted with aqueous wash liquor. In this way particulate material which reacts with hydrogen peroxide can be incorporated into an aqueous detergent liquid which contains dissolved hydrogen peroxide, whilst maintaining stability.

  • Patent number: 6063516
    Abstract: The CO concentration in the H.sub.2 feed stream to a PEM fuel cell stack is monitored by measuring current and/or voltage behavior patterns from a PEM-probe communicating with the reformate feed stream. Pattern recognition software may be used to compare the current and voltage patterns from the PEM-probe to current and voltage telltale outputs determined from a reference cell similar to the PEM-probe and operated under controlled conditions over a wide range of CO concentrations in the H.sub.2 fuel stream. The PEM-probe is intermittently purged of any CO build-up on the anode catalyst (e.g., by (1) flushing the anode with air, (2) short circuiting the PEM-probe, or (3) reverse biasing the PEM-probe) to keep the PEM-probe at peak performance levels.
