  • Patent number: 7750584
    Abstract: A motor driver comprises a first power supply, a second power supply, a multiplexer, and an output power module. The first power supply provides a first power signal after a first period. The second power supply provides a second power signal after a second period, where the second period is longer than the first period. The multiplexer initially selects the first power signal and then selects the second power signal. An output power module controls a motor and receives power from an output of the multiplexer.

  • Patent number: 7647326
    Abstract: An exemplary method and system for evaluating media-playing sets evaluates the likelihood of a selected performance condition occurring in a subject set including based on source data automatically collected from a sample group of the sets, systematic analysis of this data to form a decision tree model revealing prescribed values for characteristic input parameters that are determined to best relate to the condition, and automated comparison of the respective parameter values of the subject set to these prescribed values in order to screen each subject set for the likelihood of the condition occurring within a specified timeframe, which screening can be repeated for different conditions and timeframes using different decision tree models.

  • Patent number: 7560883
    Abstract: A circuit system and process utilizes back electromotive force (BEMF) voltage to assist in safe power down of devices, such as the read/write head in from low factor disk drives or similar devices. The BEMF voltage from a motor device, such as a spindle motor utilized in a circuit using negative voltage to drive some switches, such as positive channel metal oxide semiconductor (“PMOS”) driver transistors, to reduce and/or effectively minimize the on-resistance of the switches while delivering the current from BEMF voltage of the motor to another device, such as a motor that retracts controls a read/write head.

  • Publication number: 20080046916
    Abstract: A system and corresponding method for providing personalized assistance to users with setup of their respective media-playing sets provides a computing device remote from each set hosting a web page interface for prompting each user to create an individual account and to submit personal setup information for entry into this account; a script generator generates a personalized script for each set based on the personal setup information entered into the individual account of the corresponding user; this personalized script, by being activated, configures the corresponding set including by automatically making personalized setup selections from a plurality of preexisting setup alternatives supported by the corresponding set. These preexisting setup alternatives, for example, typically are described in a user manual accompanying or available for the set and, absent the present system and method, typically require difficult manual configuration to implement.
