  • Patent number: 7548433
    Abstract: An information handing system having apparatus for setting adequate drive strength based upon direct current (DC) trace resistance uses a resistance detection traces for each signal layer of a printed circuit board. These resistance detection traces are coupled to pull-up resistors and routed with a length and cross-sectional geometry that is substantially equal to the worst case routing of a net on a bus that is to be free of receiver mask violations (inadequate received signal strengths). Reference voltage levels may be determined for each bus so as to be representative of the minimum voltage acceptable to guarantee that the worst-case DC trace resistance will not cause the bus waveforms to fail signal integrity. A voltage comparator circuit may be used to compare the determined reference voltage levels with the voltage levels of the resistance detection traces of each of the printed circuit board layers.

In one embodiment the plate is curved and modeled to match the curved surface of a heat generating structure within the predetermined temperature range. In another embodiment the plate is a multi-layer conductive structure that is configured to undergo the same warpage under a thermal load as the heat generating structure.

    Abstract: A solar cell or solar module is measured during a short pulse of light in such a way that the resulting data for current and voltage at each light intensity is the same as would be measured under steady-state illumination conditions and therefore predictive of the actual performance of the solar cell or solar module in sunlight. A varying voltage is applied to the terminals of the solar cell during a light pulse so that the instantaneous current at a given voltage and light intensity during the light pulse is the same as would be measured under constant illumination at that same given intensity. A constant voltage is modified by a small signal correction that is proportional to the terminal current. Or, the small signal correction is proportional to the light intensity. An analog feedback circuit is constructed using the terminal current or light intensity for feedback in order to provide the requisite varying voltage. The varying voltage may also be supplied by digital synthesis.

    Abstract: A single cell oxygen sensor apparatus and method are disclosed. An yttrium-based stabilized layer having electrical terminals connected to the yttrium-based stabilized layer can be provided on a substrate, wherein the yttrium-based stabilized layer is excitable by a constant current applied to the electrical terminals. A plurality of electrodes are located on a side of the yttrium-based stabilized layer and a plurality of heater elements located on said substrate opposite said yttrium-based stabilized layer. The heater elements can maintain the yttrium-based stabilized layer at a particular temperature. A cavity is formed and located between the yttrium-based stabilized layer and the heater elements. The partial pressure of oxygen can be measured by comparing the partial pressure of oxygen within the cavity with respect to the partial pressure of oxygen in the atmosphere external to the single cell oxygen sensor apparatus.

  • Publication number: 20080189931
    Abstract: The present invention uses a frame with one or more axial ribs extending from a spine onto which two or more discrete two-terminal electronic components, such as capacitors, resistors, or inductors, can be attached. The function of the frame is to align and space the electronic components in a single device or array that allows the two-terminals of each component to be separately contacted or soldered to a PC board during final assembly into a circuit. The frame may use friction or a bonding agent to hold the components to the frame. Additionally, the base of the frame forms a single surface for the pick and place equipment used in circuit board assembly. The frame and any bonding agent must be capable of sustaining high temperature soldering operations to form electrical contacts in the circuit assembly operation.

    Abstract: Embodiments of the present invention provide a process that monitors a magnetic playback signal while gradually increasing an electricity supply amount for a heater to thereby determine contact between a magnetic head slider and a magnetic disk medium. According to one embodiment, after components for configuring a magnetic recording/playback portion are assembled into a housing, magnetic information is played back on a specific track of a magnetic disk medium by using a playback element while gradually increasing an electricity supply amount for a heater of a magnetic head slider. An amplitude of a playback signal is measured at a plurality of portions along a circumferential direction of the track. Contact between the magnetic head slider and the magnetic disk medium is detected in accordance with an increase in variation in the measured amplitude.

  • Publication number: 20080171141
    Abstract: Methods for fabricating light-emitting diode (LED) array structures comprising multiple vertical LED stacks coupled to a single metal substrate is provided. The LED array structure may comprise two, three, four, or more LED stacks arranged in any configuration. Each of the LED stacks may have an individual external connection to make a common anode array since the p-doped regions of the LED stacks are all coupled to the metal substrate, or some to all of the n-doped regions of the LED stacks may be electrically connected to create a parallel LED array. Such LED arrays may offer better heat conduction and improved matching of LED characteristics (e.g., forward voltage and emission wavelength) between the individual LED stacks compared to conventional LED arrays.
