| 20080284549 | FAULT TOLERANT SOLID STATE PUSH BUTTON CONTROL SYSTEM WITH BUILT IN DIAGNOSTIC - A contactless switch module, which is actuatable between a closed circuit position and an open circuit position, a plurality of magnetic field sensing sensors, and a plurality of magnets. The switch also includes a multi-channel switch controller. Each one of the plurality of magnetic field sensing sensors is communicatively coupled to an input channel of the multi-channel switch controller. The multi-channel switch controller is configured to determine a switch state based at least upon the respective states of its input channels. | 11-20-2008 |
| 20080265865 | SYSTEM AND METHOD FOR ADAPTIVELY DETERMINING THE TRANSITION RATE OF A QUANTIZED SIGNAL - An adaptive measurement system measures a transition rate associated with an output of a device. An input signal that is characteristic of the output of the device is received by an input signal-to-frequency converter, which changes state based upon a characteristic of the input signal. The input signal-to-frequency converter provides a second signal, which reflects the state changes of the input signal-to-frequency converter. The second signal is sampled over a sample period and an instance of average transition rate is determined. A control subsystem may use the instance of average transition rate for regulating the device. | 10-30-2008 |
| 20080265793 | APPARATUS AND METHOD TO PROVIDE A HYBRID LINEAR/SWITCHING CURRENT SOURCE, SUCH AS FOR HIGH-EFFICIENCY, WIDE DIMMING RANGE LIGHT EMITTING DIODE (LED) BACKLIGHTING - A hybrid power supply provides powers to a load, such as a light emitting diode (LED) backlight display, using pulse wave modulation (PWM) enable signal to control activation of a linear power supply and a switching power supply. During an initial part of an active portion of a duty cycle of the PWM enable signal, the linear power supply is activated to supply the load with constant current. During the remainder of the active portion of the duty cycle of the PWM enable signal, the linear power supply is deactivated and the switching power supply is activated to provide current to the load. A bias current and voltage may be provided to the LED during an inactive portion of the duty cycle of the PWM enable signal. The hybrid power supply combines the high efficiency of the switching power supply with smooth dimming control at low luminance of the linear power supply. | 10-30-2008 |
