Abstract: The present disclosure is directed to a detection device that avoids using frequencies that can potentially interfere with the operation of other electronic devices. An apparatus consistent with the present disclosure may use electrical signals of different frequencies to generate sensing signals that may be electromagnetic signals in the light spectra, for example, infrared signals may be used. Operational frequencies selected may include at least one frequency that is represented as an irrational number.

Abstract: Systems and techniques are provided for high dynamic range (HDR) with time-of-flight (TOF) cameras. An example method can include obtaining, from a TOF camera, correlation samples including a first set of correlation samples with a first integration time and a second set of correlation samples with a second integration time; determining that a first correlation sample from the first set of correlation samples is saturated; based on the determining that the first correlation sample is saturated, inferring that a second correlation sample from the first set of correlation samples is also saturated; replacing the first correlation sample and the second correlation sample with one or more scaled versions of one or more correlation samples from the second set of correlation samples; and generating an HDR TOF frame based on the one or more scaled versions of the one or more correlation samples and the second set of correlation samples.
