摘要： A reproduction apparatus has an endless web with perforations or other indicia triggering image formation and receiving sheet presentation. To correct for error in perforation location the distance between perforations is measured and a delay after sensing one or both perforations is adjusted accordingly. Preferably, the distance between perforations is measured by an encoder temporarily connected to the apparatus when a new web is installed by a serviceperson.

摘要： Image frame length control apparatus and methods are disclosed which have particular utility in a printing or reproduction apparatus that writes one or more images on a transported photosensitive media such as a photoconducting drum or continuous-loop web. When an electronic writing system or optical exposure system is used to expose a driven media on a line-by-line basis, a variation in media thickness causes the latent image frame to be written with an inaccurate frame length. Consequently, a degraded print is produced.The latent image frame length is corrected during exposure, by adding or omitting one or more lines in the image frame. Alternatively, the exposure of an image is offet by an interval corresponding to one-half of the total length discrepancy between the uncorrected image frame length and the image frame length that would be written if the media surface speed was at a median level. The overall image length error is thereby reduced by half and distributed to the upper and lower extremities of the image frame. In another embodiment, the rotation rate of the media is increased or decreased when a respectively thin or thick portion of the media passes over the driving apparatus.The corrected image fames are written with greater fidelity to the original and, after development and transfer to a receiver, are particularly well-suited for use in forming an accurate multicolor reproduction.

摘要： A health monitoring system for a fuel cell stack using current fuel cell architecture to enable the electronic control unit (ECU) to continue to monitor the health of the fuel cell stack despite a component failure. The system uses an embedded measurement module (EMM) connected to a group of fuel cells in the fuel cell stack to monitor the health of that group of fuel cells. The EMM produces a pulse width modulation signal that is sent to the ECU. A total voltage value for the group of fuel cells is embedded into the calibration signal or end of frame sequence. The ECU uses an algorithm to determine a missing voltage of at least one fuel cell in the event of the component failure of that fuel cell by adding up the cumulative value for each fuel cell reporting their voltage and subtracting that value from the total voltage value found in the end of frame sequence.

摘要： A method for providing calibration and synchronization pulses in a pulse width modulation (PWM) signal including cell voltage measurement pulses, where the calibration pulses are four calibration pulses having a pattern of a narrow width high voltage pulse followed by a wide width low voltage pulse followed by a narrow width high voltage pulse followed by a wide width low voltage pulse that has a very low probability of occurring in a practical fuel cell system. The method modulates a combined sequence of the voltage measurement signals and the calibration pulses using an inverted saw tooth wave to provide the PWM signal, where a width of the pulses representing the voltage signals are proportional to a width of the pulses representing the calibration pulses.

摘要： A tool for breaking a shaft includes two aligned tubular elements (20, 22), each having an end portion for receiving a contiguous length of the same shaft (2). Means are provided for locking each end portion against rotation relative to the shaft length received therein, and the elements are adapted for rotation relative to one another with the end portions so locked, to relatively twist the shaft lengths and shear the lengths at the interface between them. The element end portions will normally have juxtaposed faces, and it is preferred that the faces are moved towards each other during the relative rotation and as the shaft lengths are twisted relative to each other. This assists in achieving a substantially planar face at the fracture plane. A compressible washer may be disposed between the juxtaposed faces. This can stabilize the moving parts as the shaft is broken, although normally screw threads on the tubular elements will effect the movement of the element. towards each other, and this in itself may provide sufficient stability.

摘要： A coplanar die to substrate bond method wherein a plurality of die are aligned on a silicon wafer substrate in a predetermined relationship and a slurry of glass is applied to bond them together. This occurs while either on a flat or a grooved plate. When the silicon wafer substrate and the plurality of die are ready for firing, they are placed on a grooved plate so that grooves are below the glass thereby decreasing the capillary force which commonly causes overflow. With reduced overflow, the bonding can be done at a higher temperature to reduce underflow. Because there is no underflow or overflow using this process, a greater degree of coplanarity is achieved thereby making future processing steps, such as the processing of interconnect lines, much easier to perform.

The method includes providing a sequence of voltage signals representative of the voltage of the fuel cells in a fuel cell group, where the sequence of voltage signals are provided in the order of the position of the fuel cells in the group. The method also includes providing a sequence of calibration pulses and combining the sequence of voltage signals and the sequence of calibration pulses so that the calibration pulses are provided before a voltage signal of a first cell in the group.
