  • Magnetic device for attracting and retaining fasteners
    Patent number: 7204177
    Abstract: A magnetic device for attracting and retaining a fastener which has a bit, a generally ring-shaped keeper having a bottom surface, at least some portion of which bottom surface is magnetized, at least one pair of magnets, each pair of magnets having two magnets with alternating poles, adjacent to the magnetic bottom surface of the keeper and arranged around the bit such that an even number of magnets with alternating poles is arranged around the bit, and a non-magnetic holder that secures the keeper and the magnets and surrounds the bit. The magnets provide magnetic flux to the keeper and the fastener. Each pair of adjacent magnets provides a closed magnetic flux path through a first magnet of the pair, the keeper, a second magnet of the pair, and the fastener. The location of the magnetic device along the bit may be adjustable or fixed.

  • Technique for determining a tuning frequency of an audio receiver
    Patent number: 7206558
    Abstract: A technique for determining a tuning frequency of an audio receiver includes interrupting a received radio frequency (RF) signal at an input of the audio receiver. Next, a modulated audio signal is injected into the input of the audio receiver. Then, it is determined whether the demodulated audio signal is present at an output of the audio receiver. If not, the frequency of the modulated audio signal is changed until the demodulated audio signal is detected at the output of the audio receiver.

  • Method of diagnosing a low range limiting malfunction of an engine coolant temperature sensor
    Patent number: 7203617
    Abstract: Low range limiting malfunctions of an engine coolant temperature (ECT) sensor are diagnosed by comparing a change in the sensed temperature during engine operation with a calibrated temperature change. If the change in sensed temperature fails to exceed the calibrated temperature change, and a diagnostic for detecting a stuck ECT signal is either inconclusive or passed, a low range limiting malfunction of the sensor is indicated. If the diagnostic for detecting a stuck ECT signal is failed, the low range limiting diagnostic concludes with no report even if the change in sensed temperature fails to exceed the calibrated temperature change.

  • Integrated self-cooling plant support module for a fuel cell system
    Patent number: 7201984
    Abstract: An integrated system for air-cooling a main air blower drive motor and electronic control module in a fuel cell plant support module (PSM) disposed in an enclosure. Process air is drawn by a main blower fan into the enclosure through a filter and then is drawn from the enclosure into the blower via a first shroud surrounding the electronics process control module (ECM) and a second shroud surrounding the blower motor. The air cools these components and is thereby desirably warmed before being directed to the fuel cell assembly via an air distribution system. Thus, the PSM is constantly cooled and purged through the downstream processes, and the incoming air is constantly warmed by recovered heat from the PSM.
