Method and device for acquisition of data from a multicontact matrix tactile sensor
First Claim
1. A data acquisition method for acquiring data from a multicontact matrix tactile sensor that has a matrix array of a plurality of cells, the method comprising:
- scanning the plurality of cells of the matrix array sequentially;
measuring an electrical characteristic of a first cell of the plurality of cells, the electrical characteristic being representative of a weight of the first cell;
comparing the weight with a predetermined significant weight value interval;
storing cell data associated with the first cell, the cell data including the weight and coordinates of said first cell in the matrix array, after said step of comparing has determined that the weight of the first cell lies within the predetermined significant weight value interval;
verifying an existence of a data record associated with neighboring cells located in a neighboring zone of said first cell; and
updating the data record associated with the neighboring cells of said first cell by storing the cell data associated with said first cell, and which includes the weight of the first cell, in the data record associated with the neighboring cells, after said step of verifying has determined the existence of the data record associated with the neighboring cells.

Abstract
A data acquisition method to acquire data from a multicontact matrix tactile sensor having a matrix array of a cells, includes scanning the cells of the matrix array sequentially, and measuring an electrical characteristic of a cell, which represents a weight of the cell. The method also includes comparing the weight with a predetermined significant weight value interval, storing cell data associated with the cell, where the cell data includes the weight and coordinates of the cell in the matrix array, after the weight is determined to lie within the predetermined significant weight value interval. The method also verifies an existence of a data record associated with neighboring cells in a neighboring zone of the cell, and updates the data record associated with the neighboring cells by storing in the data record data associated with the cell, after the existence of the data record is confirmed.
