摘要： First events corresponding to detecting a reflection off a reference object are detected. Second events corresponding to detecting a reflection off a remote object are also detected. A histogram having a first peak corresponding to the first events and a second peak corresponding to the plurality of second events is generated. A distance between the remote object and the reference object is determined in dependence on a time between the first peak and the second peak of the histogram.

摘要： An optical sensor includes an infra red LED, a photodetector and a lock in charge amplifier. The photodetector passes charge to a feedback capacitor of the charge amplifier following an illumination cycle during which the LED is emitting and also following an illumination cycle during which the LED does not emit. An amplifier presents an output indicative of the difference between the charge generated at the photodetector during the illuminated and non-illuminated cycles.

摘要： A camera module with a fixed near field focus is configured to capture a single image. That single image is segmented by an image divider a number of regions. A focus metric determiner then determines a focus metric for each of the regions. A depth map generator maps the focus metric into a depth value for each of the regions and combines the depth values to generate a depth map.

摘要： Systems and methods for generating a CDMA signal s(t) comprising N components involves assigning to each of the N components one unique spreading sequence an selected from a set of M spreading sequences with M≧N, modulating the symbols dn of each component on the assigned unique spreading sequence an, and combining the N symbols dn each being spread with its own unique spreading sequence an to a CDMA signal s(t). The assigned spreading sequences an are selected such that all selected pairs within the set of N spreading sequences are orthogonal or very close to be orthogonal so that cross-correlation components between all spreading sequences an are close to zero or zero.
