  • Patent number: 6834661
    Abstract: A control valve system includes a housing having an inlet port, a first output port, a second output port, and a valve chamber. A primary spool and a secondary spool are independently slidable in the valve chamber. The secondary spool has a first end for abutting against the primary spool and has a second end with a working surface area greater than the working surface areas at the ends of the primary spool. A solenoid valve assembly controllably connects the inlet port to the second end of the secondary spool. A biaser provides a biasing force to the primary spool. A first fluid passage through the primary spool provides fluid communication between the first output port and a second end of the primary spool for displacing the primary spool relative to the secondary spool in an energy saving mode, thereby regulating a pressure at the first output relative to the predetermined magnitude of the biasing force.

  • Patent number: 6326241
    Abstract: A solderless method for assembling a semiconductor electronic flip-chip device to an electrical interconnecting substrate including the steps of forming a plurality of raised electrical contacts and plurality of contact pads. The pads correspond in number and physical location with the electrical contacts. The pads and contact mate when brought together. A quantity of plastic material is interposed between the electrical device and substrate. The plastic material is heated so that it softens and flows. The electronic device and substrate are urged together. The urging step displaces the molten plastic material from between the contacts and pads. The contacts and pads are jointed directly without any adhesive, solder or conducive filler therebetween to electrically interconnect the electronic device and substrate. The plastic material is allowed to cool whereby the electronic device and substrate are adhesively bonded together and electrically interconnected.

  • Patent number: 6259287
    Abstract: A regulated voltage supply contains a zener diode controlled by a constant current generator to maintain the zener voltage at a constant level regardless of the swings of the voltage input to the diode. A current amplifier responds to the constant current generator to maintain the output voltage of the regulated voltage supply at the value of the zener voltage regardless of the demands of the load. A low voltage inhibit circuit responds to the magnitude of the input voltage and the magnitude of the voltage on the zener diode to generate a binary voltage signal for inhibiting the operation of a load such as a microcomputer when the voltage regulator is below the zener voltage level and the input is below the desired voltage.

  • Patent number: 6210102
    Abstract: A pump (10) has a housing containing an internal pumping chamber (30). A fluid inlet (32) and a fluid outlet (34) are spaced arcuately apart about an axis (12), and an impeller (20) within the housing rotates about the axis to pump fluid from the inlet to the outlet. The impeller has mutually parallel opposite faces (40, 42) circumferentially bounded by a vaned periphery (38). The impeller has a pattern of through-holes (46) extending between its faces and the one face that confronts a wall surface of the housing to which the inlet is proximate has, in association with each through-hole, a groove (44) that adjoins and tails circumferentially away from the respective through-hole in a sense opposite the sense in which the impeller rotates to pump fluid from the inlet to the outlet. The groove inclines and provides a reaction surface against which fluid exerts a lifting force to aid in force-balancing the impeller.

  • Patent number: 6191579
    Abstract: A rotary position sensor having redundant sensing including a base (20) upon which a plurality of radially extending magnetic sensing elements (22) are mounted to form two sets (74, 76) of sensors. Interleaved with the sensing elements (22) are a plurality of uniformly spaced magnetic concentrators (30). The sensor assembly (18) is placed in a uniform magnetic field created, for example, by a flat plate magnet (432) mounted adjacent the sensor assembly, and rotatable relative to it. The relative rotary position of the sensor assembly to the magnetic field is determined by comparing the relative values of the sensor elements (22) in the array to each other. Also, failure of the sensor assembly is determined by comparing the rotary position calculated for the first set 74 to the rotary position calculated for the second set 76.

  • Patent number: 6173166
    Abstract: An FM radio receiver predicts the onset of a multipath event based on a derivative of a noise detection signal and then further monitors the multipath event as it progresses. During multipath, an audio output pans between a normal signal path and a multipath smoothed signal path which includes a multipath smoothing filter. If multipath distortion is present long enough, the mixer pans completely over to the smoothing filter path. If the event is weak, only partial panning takes place and mixing is restored to the normal signal path.

  • Patent number: 6067007
    Abstract: A security system for an automotive vehicle including a positioning device which, in cooperation with a Global Positioning System ("GPS") satellite network provides location information regarding the vehicle's position. The security system further includes a passive operator identification device having a first security code and a theft control unit including memory storing a second security code. The passive operator identification device and the theft control unit work together to ensure the vehicle operator is authorized to operate the vehicle. An event detector communicates with the theft control unit to provide an event signal associated with the vehicle such as vehicle movement. If an event signal is received by the theft control unit, and the first and second security codes are not equal, the theft control unit communicates the vehicle position as determined by the position detector to a monitoring station.

  • Patent number: 6064865
    Abstract: A space diversity, multiple-tuner radio receiver obtains substantially noise free reception under most signal conditions. The tuner outputs are mixed in proportion with the signal quality as determined by detecting noise in each tuner output signal. Long-time-delay multipath distortion, adjacent channel interference, and co-channel interference are reduced by selecting predetermined antenna pattern combinations in response to high noise levels being present from both tuners.

  • Patent number: 6061455
    Abstract: An audio system for a vehicle comprises an audio amplifier 14 and a manually adjustable volume control 18 for setting the output level of the sound generated by a loudspeaker 20 connected to the output of the amplifier 14. The amplifier 14 includes distortion sensing means for detecting when the level of distortion of the output signal of the amplifier 14 exceeds a reference threshold and a control circuit 16 reduces the sound output level of the amplifier in response to a signal from the distortion sensing means. The reference threshold of the distortion sensing means 14 is varied in dependence upon the output level setting of the volume control 18 so that the allowable output distortion can be varied based upon user input.

  • Patent number: 6055318
    Abstract: An infinite impulse response (IIR) lowpass filter is placed in the audio path of an audio system wherein the upper cutoff frequency of the filter is adaptively controlled based on a comparison between the average audio signal entering the filter and the average audio signal leaving the filter. An adaptive LMS process is used to control the filter bandwidth so that the average output signal reaches a predefined percentage of the average input signal. An adaptation rate is selected depending on whether the filter bandwidth needs to increase or decrease. Adaptation is fastest for increasing bandwidth and slowest for decreasing filter bandwidth to prevent audible breathing and loss of high frequency information on sudden signal transients. Adaptation is disabled (at least to the extent that decreasing of the filter bandwidth is disabled) whenever low signal modulation is detected.
