  • Patent number: 8280074
    Abstract: An audio signal processing apparatus for outputting an input digital audio signal as a positive phase PWM signal and a negative phase PWM signal. The resolution of the input digital audio signal is converted to a low resolution and noise shaping is performed to generate a positive phase digital signal (REF_P) and a negative phase digital signal (REF_N). Both signal patterns are compared at a buffer and pattern comparator section when muting. If the signal patterns match, a selector outputs a set value having 50% duty instead of the digital signals to optimize timing for switching to 50% duty when muting.

  • Publication number: 20120074856
    Abstract: Short circuit failures and open circuit failures of light-emitting elements used for the backlight in an LCD panel can be reliably and easily detected. The voltage at the node between each series-connected light-emitting element array and a drive circuit is detected as a monitored voltage. A maximum detector detects the highest and a minimum detector detects the lowest of these monitored voltages. Short circuit or open circuit failure of a light-emitting element is detected by comparing the voltage difference between the maximum detector output and the minimum detector output with a specific reference voltage.

  • Patent number: 8030877
    Abstract: In a back electromotive force phase detecting device, a timing generating unit generates a timing signal indicating a start timing, an intermediate timing and an end timing of a 180-degree electrical angle period in a detection target phase, from an excitation pulse signal. A difference calculating unit receives the timing signal, and calculates a difference between a total PWM control period of the detection target phase during a first-half 90-degree period, and a total PWM control period of the detection target phase during a second-half 90-degree period. In an excitation control device, a control unit changes the capability of driving a motor based on an output of the back electromotive force phase detecting device.

  • Patent number: 7925928
    Abstract: After power activation, a transferer 14 detects a bootstrap program 111 having a first error check code 114 assigned thereto and being stored in a first storage device 11, subjects the bootstrap program 111 to an error detection/correction process, and transfers the bootstrap program 111 to the second storage device 12. If the transfer is properly completed, by executing the bootstrap program 111 on the second storage device 12, the CPU 10 performs an error detection/correction process for a main program 112 having a second error check code 115 assigned thereto, and transfers the main program 112 to a third storage device 13, after which the CPU's control branches out to the main program 112 on the third storage device 13. As a result, system boot can be performed without employing a NOR type flash memory.

  • Patent number: 7768226
    Abstract: Problems with accuracy reading position detection signal peaks and minute phase differences in the detection current make motor drive control easily susceptible to differences in motor characteristics. The rotor position is determined based on whether or not a terminal difference voltage, which is the difference voltage between the motor terminal voltage and the pseudo-neutral-point voltage when the motor phases are selectively energized, exceeds a specific threshold value. The phase energized to start the motor is determined based on this determination and the motor is energized accordingly to start. Instead of switching directly from the search step at the initial rotor position to the back-EMF voltage mode, a search and start mode that creates initial rotor speed sufficient to start the motor is executed before entering the back-EMF voltage mode.
