Optometric digital photo pedometer for recording e.g. footprint of human, has transducers mounted on optical drive unit by charge-coupled device reading units, and optical drive unit defining sensing zone

摘要

The pedometer has multiple transducers (10, 11) attached with a transparent layer (18) and translucent layers (19, 20, 24). The transducers are mounted on an optical drive unit (3) by charge-coupled device (CCD) reading units (4, 5). The optical drive unit defines a sensing zone. A guiding unit (12) is attached with the transducers.
