<p>Methods and systems for implementing an improved mouse optical sampling scheme are disclosed. At least one counter state machine (320, 324) is used to control at least one PTR state machine (328). At least one PTR state machine is used at a sample rate in order to determine the appropriate output for the mouse. The sample rate is adjusted to minimize the system sensitivity to poor duty cycle regulation. In addition, response time Tmin value(s) are adjusted in order to optimize the duty cycle for each PTR state machine. The mouse output is then provided to the computer. Consequently, by optimizing the duty cycle for each PTR state machine and minimizing its sensitivity to poor duty cycle regulation, a greater dynamic range of optical components can be employed in the mouse. <IMAGE></p> |
