Pulse-width modulation amplifier and suppression of clipping therefor
ActiveUS20060008095A1Avoid excessive currentPower use efficiency decreaseAmplifier modifications to reduce noise influenceGain controlLeading edgeAudio power amplifier
A pulse-width modulation (PWM) amplifier is adapted to a class-D amplifier in which an analog input signal is subjected to integration, pulse-width modulation, and switched amplification, wherein a glitch elimination circuit eliminates noise from a pulse-width modulated signal, from which a high pulse signal and a low pulse signal are isolated such that each pulse is delayed by a dead time at the leading-edge timing thereof. When both of them are simultaneously set to a high level, one of them is reduced in level. In response to the occurrence of clipping, an integration constant applied to an operational amplifier is automatically changed from a primary integration constant to a secondary integration constant. When the clipped state is sustained for a prescribed time, an inversion pulse is compulsorily introduced into the pulse-width modulated signal.

ActiveUS20110228104A1Save processing timeNoise is causedProjectorsColor television detailsCamera imageGrating
A first Gray code technique and a second raster calibration technique can be combined to create a precise mapping between pixel locations of the camera and pixel locations of the projector(s). In one aspect the technique of using the raster calibration images is eliminated by interpolating the projector coordinate information decoded from the Gray code images. In another aspect camera images are processed to reduce errors caused by noise so that text can be displayed without any noticeable misalignment between projectors. In a third aspect, a scale factor is calculated based on the relative height / width of projector regions in the captured calibration images. Calibration images are recalculated using the scale factor to provide greater correspondence between the mapping of a low resolution camera to the high-resolution projectors.
