  • Patent number: 6405714
    Abstract: A method for calibrating an electronic control unit for an internal combustion engine. The electronic control unit may have multiple channels with each channel being adapted to provide an input drive signal to a fuel delivery apparatus. A first channel is selected for calibration. A reference signal of desired and known parameters is also defined. The reference signal is defined such that it is indicative of the cyclical performance of a fuel delivery apparatus such as a fuel injection device. A command signal is generated and passed through the circuitry of the selected channel. The channel circuitry generates a drive signal in response to the command signal. A desired parameter of the drive signal is measured for comparison with the known parameter of the reference signal. If necessary, the command signal is then adjusted so as to produce a modified drive signal which has a parameter with reduced variation from the known reference parameter.

  • Patent number: 6402373
    Abstract: A method is provided for determining source-to-image distance (SID) setpoints in a digital radiographic imaging system. SID setpoints are determined during a setup and calibration procedure which includes generating x-ray beams while varying certain system parameters, such as the x-ray source position or the size of the collimator opening, and detecting and determining the size of the x-ray beams that impact on the digital detector. SID values and a separation gain constant can then be determined based on the calculated sizes of the detected x-ray beams and the feedback signals which are representative of the various system parameters that were varied (e.g., source position, collimator blade position, etc.) during the setup and calibration procedure. The separation gain constant and the calculated, empirical SID values can then be used to position the x-ray source at any user-selected SID based on position sensor feedback signals.

  • Patent number: 6401696
    Abstract: A fuel injection device works based on the principle of storage of energy in a solid body and is designed as a reciprocating piston pump with a feeding piston (35, 24) that stores kinetic energy during an almost resistance-free acceleration phase. The stored kinetic energy is abruptly transmitted to the fuel contained in a compression chamber (66), generating a pressure wave for injecting fuel through an injection nozzle. The means that interrupt the resistance-free acceleration phase are designed as a valve with a valve body (50a) and a valve seat (57) shaped on the feeding piston (35, 24). To generate the pressure wave, the valve closes the compression chamber (66) so that the kinetic energy of the feeding piston (35, 24) is transmitted to the fuel enclosed in the compression chamber (66). The valve seat (57) and the valve body (50a) lie at the front end of the feeding piston (35, 24), seen in the direction of injection, and separate the compression chamber (66) from the feeding piston (35, 24).

  • Patent number: 6398511
    Abstract: A reciprocating pump includes a drive section and a pump section. The drive section has a reciprocating coil assembly to which alternating polarity control signals are applied by a reciprocating circuit during operation. A permanent magnet structure of the drive section creates a magnetic flux field which interacts with an electromagnetic field produced during application of the control signals to the coil. Depending upon the polarity of the control signals applied to the coil, the coil is driven in one of two directions of movement. The reciprocating circuit employs a storage capacitor and several switches to capture the energy of the reciprocating coil as the pump is driven downwardly. The charge is recycled as the capacitor dissipates, thereby reversing the polarity of the current through the coil and driving the coil assembly upwardly to its initial position.

  • Patent number: 6388199
    Abstract: A method of selectively adjusting surface tension of a soldermask material. Specifically, a method of selectively adjusting the surface tension of a soldermask material to promote adhesion of a molding compound in a ball grid array package while maintaining a low surface tension on the ball attach area to prevent bridging between the solder balls. Solder balls require a low surface tension soldermask to minimize bridging, while the molding compound requires a high surface tension to provide adequate adhesion to the surface of the soldermask. By exposing selected portions of the soldermask to an activation method, such as ultra-violet radiation, the surface tension of the soldermask can be varied such that different areas of the package exhibit different surface tensions.

  • Patent number: 6389555
    Abstract: A system and method for maintaining a communications within a computer system after a data transport failure across a first link. Fail-over capability is attained by re-establishing communications across a secondary link using different transport mechanisms. Between two Input/Output Processors (IOPs) within a computer system, such as a server, a series of data transactions therebetween are queued until transaction completion. Upon detection of a failure condition between the IOPs across the first link, the IOPs engage fail-over mechanisms to preserve uncompleted data transactions until communications are re-established across the secondary link.

  • Patent number: 6384655
    Abstract: A comparison circuit may be fabricated along with a primary circuit on a semiconductor substrate. The propagation delay of a comparison signal across a first path of circuit elements is compared to propagation delays of the comparison signal across a second path of delay elements. As a semiconductor fabrication process varies, the relative propagation delays across the first and second paths will vary in a manner correlative to the process variations. By monitoring the relative propagation delays, the fabrication process may be controlled to ensure that the process does not vary to an undesirable extent. Also, various programmable delay elements may be fabricated into the primary circuit, and these programmable delay elements may be activated and/or deactivated in response to the relative propagation delays of the comparison circuit.
