Abstract: A time of flight (ToF) system includes a light source, a photosensor, a signal generator and a processor. The signal generator outputs a reference signal corresponding to a modulation function for modulated light and a modified transmitted light signal corresponding to a phase shift of the reference signal. The light source outputs the modified transmitted light signal and pixels in the photosensor receives its reflections off the scene. The reference signal is applied to the pixels and the processor determines a depth map for the scene based on values recorded by the pixels. In some examples, the phase shift is implemented using a phase locked loop controller. One or more component phases of the phase shift and an exposure time for each component phase are determined and output by the phase locked loop controller.

Abstract: Systems, apparatus, articles of manufacture, and methods are disclosed to detect a pace pulse in an electrocardiogram (ECG) signal. An example apparatus includes programmable circuitry configured to execute instructions to: identify a leading edge of a pulse in an input signal based on an amplitude change; identify a transition time of the leading edge of the pulse; validate the leading edge of the pulse based on the amplitude change and transition time; identify a trailing edge of the pulse; determine a width of the pulse between the leading edge and the trailing edge; and validate the pulse based on the width.
