1. An apparatus, comprising:
- a fine sensor array comprising an array of fine pressure sensors and a coarse sensor array comprising an array of coarse pressure sensors wherein the fine sensor array and the coarse sensor array are positioned to overlap, the fine and coarse pressure sensors operable to produce respective pressure signals in response to pressure applied thereto, at least some of the pressure signals quantifying the pressure with greater than single-bit resolution, the coarse sensor array having a different spatial resolution than the fine sensor array; and
a processor operable in response to the pressure signals to generate an information signal representing a spatial distribution of pressure applied to at least one of the fine sensor array and the coarse sensor array.

Abstract
A spatial pressure distribution sensor comprises a sensor array and a processor. The sensor array comprises an array of pressure sensors. Each of the pressure sensors is operable to generate a respective pressure signal in response to pressure applied to it. The pressure signal quantifies the pressure with greater than single-bit resolution. The processor is operable in response to the pressure signals to generate an information signal representing the spatial distribution of pressure applied to the sensor array.
