    Abstract: A method includes counting a first set of photons having a time-of-flight that falls within a first time range and being detected during a first time period, determining a second time range based on the first set of photons, the second time range being smaller than the first time range, counting a second set of photons having a time-of-flight that fall within the second time range and being detected during a second time period, and determining a third time range based on the second set of photons, the third time range being smaller than the second time range.

    Abstract: A system for edge enhancement includes an input unit to receive an input signal Yin, a vertical enhancement unit to perform a vertical enhancement of an edge of the input signal Yin to generate an output YEV, and a horizontal enhancement unit to perform a horizontal enhancement of the edge of the input signal Yin to generate an output YEH. The system also includes a local gradient analysis unit to generate a local gradient direction GradDir and a local gradient magnitude GradMag based at least partly upon the input signal Yin, and a mixer to generate an output Yout by mixing the output YEV with the output YEH using the local gradient direction GradDir. The system further includes an output unit to output the output Yout.

    Abstract: A method of measuring the phase of a response signal relative to a periodic excitation signal, comprises the steps of producing for each cycle of the response signal two transitions synchronized to a clock and framing a reference point of the cycle; swapping the two transitions to confront them in turns to the cycles of the response signal; measuring the offsets of the confronted transitions relative to the respective reference points of the cycles; performing a delta-sigma modulation of the swapping rate of the two transitions based on the successive offsets; and producing a phase measurement based on the duty cycle of the swapping rate.

    Abstract: A system comprises a resource, such as an interconnection, for example, of the Network-on-Chip (NoC) type, having an overall bandwidth available for allocation to a set of initiators that compete for allocation of the overall bandwidth. The system includes a communication arbiter for allocating the overall bandwidth to the initiators according to respective values of bandwidth requested (RBW) by the initiators. A control device (50) is configured to detect the deviation between the value of bandwidth allocated to the initiators and the respective value of requested bandwidth and allocate the overall bandwidth to the initiators in a dynamic way minimizing the mean value of the deviation.
