摘要： A disk drive power manager that compares energy usage with a predetermined profile to select one of several reduced-power operating modes. An energy usage register is updated at regular intervals according to the energy used during each time interval. An attenuated average energy usage value is obtained by attenuating the energy usage measures over time and integrating the results. The average energy level is compared with several predetermined energy threshold profiles to select a full- or reduced-power operating mode. Operating mode selection automatically adapts to the usage pattern to optimally balance power consumption with operational accessibility.

摘要： A circuit for concurrently producing low noise electrical output signals which are amplified representations of signals produced by a magnetoresistive (MR) element and protecting said element from electrical short circuits which can occur between said element and its environment. A first feedback loop comprises (a) an input amplifier for amplifying a signal current from the MR element and (b) a source of bias current for biasing the MR element with a bias voltage. An input amplifier is concurrently biased by said current and amplifies a signal current from the MR element for producing a circuit output signal corresponding to dRh/RhRh and in which any differential direct current (dc) output offset error is minimized. (RhRh is the square of the time-averaged resistance of the MR element and dRh is the magnetic-signal-induced change in the resistance of the MR element.) A second feedback loop, electrically in series with the first feedback loop, biases the MR element toward a preselected reference potential and concurrently prevents flow of a current sufficient to damage the MR element in the event of a short circuit occurring between the MR element and its environment (e.g. the recording surface of a magnetic recording disk).

摘要： A new and improved apparatus for tightening a chain installed on a tire that is mounted on a wheel of a motor vehicle includes a hub assembly and a plurality of tension assemblies. Each tension assembly includes a first end for connecting to the hub assembly, a tensioning element connected to the first end, and a second end connected to the tensioning element. The second end is connected to a portion of the chain, such that the hub assembly and the tension assemblies exert tension on the chain in a radial direction toward the hub assembly. More specifically, the tension assemblies are attached to the hub assembly and the chain in pairs, and the tension assemblies of each pair are arranged in opposed relation. That is, the first ends of each pair are in opposed relation with respect to the hub assembly, and the second ends of each pair are in opposed relation with respect to the chain. At least one of the tension assemblies further includes a threaded shaft movable within a sleeve. The hub assembly contains a quantity of a de-icer liquid which is dispensed through a portion of the sleeve. A metering valve connected to the threaded shaft allows the metering of the de-icer liquid to be adjusted.

摘要： A write drive logic circuit is described. The write driver logic circuit comprises a set of write drivers, with each one of the set of write drivers having an input and an output, such that each write driver is responsive to an input signal applied to the input to provide a write output signal at the output as a function of the input signal. A set of memory devices (e.g. shift registers) is provided, one for each write driver. Each one of the shift registers stores unique head identification information and includes an output to controllably output a signal representative of the unique head identification information. Furthermore, each one of a set of multiplexers includes an output, a first input coupled to a corresponding one of the outputs of the set of shift registers to receive the signal representative of the unique identification information stored in the respective shift register and a second input coupled to a common write data line that transmits a signal representative of preselected information. The output of each one of the set of multiplexers is coupled to the input of a corresponding one of the set of write drivers such that one of the first and second inputs of the multiplexer is selectively applied to the input of the corresponding write driver.
