Abstract: Techniques are disclosed for detection and ranging systems and methods to improve range resolution, target separation, and reliability. A method includes selectively attenuating a signal representing a ranging system return or echo from targets so as to suppress side lobes or other undesirable artifacts appearing in the signal due to noise, interference, and/or distortion. A method may additionally or alternatively include rejecting interference events in ranging system returns by comparing a received return with that expected from a target illuminated by the ranging system, as determined by characteristics of its particular ranging sensor, and rejecting or attenuating returns or portions of returns that fail to match those characteristics in time or space.

Abstract: In one embodiment, a method for restructuring distorted capacitive touch data includes receiving an array of touch amplitude data associated with an electrode line of a capacitive touch sensor in response to a touch on a touch sensitive display. The method also includes detecting a distortion in the array of touch amplitude data and calculating, in response to detecting the distortion, a corrected array of touch amplitude data such that the corrected array of touch amplitude data represents the touch on the touch sensitive display.

Abstract: The invention concerns a method of signal processing which is applicable in particular to radar systems. The signal is first filtered, and then values of the filtered signal which in the time domain are below a base line level are clipped. The process is then iterated. The filter in question is of low pass type. The filter may be digital, in which case it can be implemented using a “kernel” comprising 10 or even fewer coefficients.
