Abstract: To establish an initial/resting position of a permanent magnet rotor, all motor stator windings are stimulated (voltage applied thereto) in sequence, the time it takes for current in the stimulated stator winding to rise to a specific current value is measured for each stator winding and these time measurement results processed. From the measured time results rotor position to within 60 degrees is determined and the position sector is known prior to starting/rotating the motor. Once the rotor position is known, the next commutation point in a six step sequence is known before actually starting/rotating the motor. Position measurement winding stimulation may be interleaved with commutation pulses, or the unexcited stator winding may be stimulated between commutation pulses to the other two excited stator, wherein one of the two stator windings remains connected to the power and provides a current return path to the unexcited but stimulated stator winding.

Abstract: Efficiency of a switch mode power supply (SMPS) is optimized by operating the SMPS in an asynchronous mode when current being supplied therefrom is less than a certain current value and operating the SMPS in a synchronous mode when the current being supplied therefrom is equal to or greater than the certain current value. When the SMPS is operating in the synchronous mode high-side and low-side power transistors alternately turn on and off. When the SMPS is operating in the asynchronous mode only the high-side power transistor turns on and off and the low-side power transistor remains off. When charging a battery with the SMPS discharge of the battery is eliminated when operating in the asynchronous mode at a low current output.

Abstract: Power supply modules have outputs coupled in parallel and convey load share balancing information over a single wire load share bus. Pulse width modulation (PWM) signals represent output loading of each of the power supply modules over the single wire load share bus. The PWM load share signal width (time asserted) of the PWM signal represents the output loading of the respective power supply module. Each of the power supply modules detect the assertion of the PWM signal on the load share bus and then each of them simultaneously drive the load share bus with a PWM signal representing their respective output loading. The power supply module having the greatest percent loading will assert its PWM load share signal longest, and the other power supply modules will thereafter adjust their outputs to more evenly supply power outputs to the load.

Abstract: Power consumption of a device having a resistive touch screen may be reduced if the resistive touch screen is not scanned unless a touch thereto is imminent, especially if the device can remain in a low power sleep mode during no-touch inactivity. Furthermore, detecting a potential touch earlier then an actual first touch may improve initial touch response time. The resistive touch screen may comprise top and bottom Indium Tin Oxide (ITO) coated planes. The top ITO coated plane may be used as a capacitive proximity detector and the bottom ITO coated plane may be used as a guard shield for the top ITO coated plane to significantly reduce parasitic capacitance thereof and enhance the sensitivity of capacitive proximity detection. The device may also remain in a low power sleep mode until a potential touch is detected thereby further saving device power consumption.

Abstract: Extending pulse width modulation phase offset when generating phase shifted groups of pulse width modulation (PWM) signals is accomplished with a separate phase counter that is independent of the time-base counters used in traditional PWM generation circuits and that is prevented from being re triggered until an existing duty cycle has completed. This is accomplished with a phase offset counter, a phase comparator and a circuit that is triggered via a master time base for overall synchronization of the multi-phase PWM signal generation.

Abstract: A voltage regulator has a regulated output voltage that is maintained up to a current limit, Ilimit, then as the load continues to decrease in resistance (impedance) the current does not increase past the current limit, Ilimit, but rather the output voltage decreases forcing the output current to also decrease to satisfy Ohm's Law: lout = Vout/ZLoad- When the output voltage starts dropping below the regulated voltage value because of current limiting the voltage regulator shifts from a current limit mode to a current foldback mode wherein the output current decreases with the decrease in output voltage until the output current reaches a current foldback minimum, Ifoldback, at an output voltage of substantially zero volts. As the load resistance (impedance) begins to increase so will the output voltage and thus output current until the output voltage is back at substantially the regulation voltage value, and the output current is less than or equal to the current limit, Ilimit.
