  • System and method for data communications using an adaptive pulse width modulation protocol
    Publication number: 20040174933
    Abstract: A system and method for pulse-width-modulation (PWM) communications using an adaptive pulse-duration threshold. In this embodiment, a PWM device will analyze a data string from a PWM transmission from a second device, and adaptively determine an appropriate pulse-duration threshold for that communication. After doing so, the PWM device can then receive and transmit data as needed with the second device. This adaptive PWM protocol can enable effective communications with multiple devices with different configurations.
