Abstract:
1. A plate having a plurality of pressure sensors at spaced locations therein to measure pressure exerted against a substantially smooth measuring surface of the plate at the locations of the pressure sensors, comprising: a plate having a substantially smooth measuring surface against which a liquid can act; a plurality of cavities in the plate under the measuring surface; deformable portions of the measuring surface of the plate extending over each of the plurality of cavities and resiliently deformable into the cavities in response to pressure applied to the deformable portions of the measuring surface; and a single sensor in each of the plurality of cavities, each sensor cooperable with the deformable portion of the measuring surface extending over that cavity to sense the deformation of such deformable portion and provide a signal indicative of a single deformation sensed, the deformation of the deformable portions being indicative of the pressure applied to such deformable portions.
