Abstract
In embodiments a circuit provides a circuit for use in detecting close proximity objects in an acoustic distance sensing system. The circuit produces a close proximity zone flag when the time after transmitting an acoustic distance sensing pulse corresponds to the defined close proximity range. The circuit can also include a time of flight counter for determining the time of flight of a received echo. The circuit can further produce a close proximity time if flight valid flag indicating that echoes are being received in close proximity time frame.
