COMPUTER MOUSE PRESSURE ACQUISITION MODULE

摘要

A pressure acquisition module for a computer mouse having a button. The pressure acquisition module comprises a momentary switch, a pressure sensor, a sampler and a digital processor. The pressure sensor is operative to measure a pressure applied on the button of the computer mouse and to send a raw analog sensor signal. The sampler is operative to convert the raw analog sensor signal into a digital pressure signal. The digital processor is operative to filter out a parasitic oscillation from the digital pressure signal. The parasitic oscillation may be caused by the momentary switch being activated. The digital processor is further operative to output a corrected shaped pressure signal. In a second embodiment, there is a pressure acquisition module for a computer mouse having a button. The pressure acquisition module comprises a pressure sensor, a sampler, a transducer and a digital processor. The pressure sensor is operative to measure a pressure applied on the button of the computer mouse and to send a raw analog sensor signal. The sampler is operative to convert the raw analog sensor signal into a digital pressure signal. The transducer is operative to generate a momentary facsimile switch click. The digital processor is operative to generate a transducer signal in response to a pressure for generating a click.
