Scanner and method for detecting pressures on a member

摘要

A scanner and associated method for detecting pressures on a test member are provided. The scanner can be provided with an electronic module that includes an analog-digital (A/D) converter associated with each channel of the scanner and configured to provide digital signals representative of the pressures detected by pressure sensor elements associated with various locations on the test member. The electronic module can also include amplifiers and/or a multiplexer so that the output of the scanner provides an amplified and/or multiplexed digital output signal representative of the detected pressures. In some cases, the A/D converters and amplifiers can be provided in a single, mixed-signal chip of the scanner. The scanner can be small enough to be disposed in various locations in the test member, including small spaces that are generally incapable of accommodating conventional test equipment.
