Abstract: A pulsed-light detection and ranging apparatus comprises an optical detector arranged to generate, when in use, time-series data in response to an optical pulse incident thereupon. A processing resource is also provided and arranged to support a pulse analyser (132). The pulse analyser (132) is arranged to identify (134) an inflection point of a pulse described by the time-series data. The pulse analyser (132) is further arranged to calculate (138) a distance based upon determined inflection point relative to a time axis associated with the time-series data.

Abstract: A toggled buffer memory apparatus comprising a first memory block (134) arranged to support the first memory function over a first time frame and to toggle to support the second memory function over a second time frame. A second memory block (136) is also arranged to support the second memory function over the first time frame and to toggle to support the first memory function over the second time frame. A data input and a self-test block are respectively operably and selectively coupled to the first and second memory blocks. A controller is arranged to control toggling of the memory blocks (134, 136) which are each arranged to toggle between the first and second memory functions in respect of time frames subsequent to the second time frame.
