  • Signaling method and apparatus with a host and human input device
    Patent number: 6668180
    Abstract: In the exemplary system, a “software” handshake is employed to signal from the keyboard when it is desired to “wake up” the host. After the handshake is completed, a key scan code is communicated to the host. Thereafter the host may revert to “sleep” mode until another keystroke (press or release) occurs. This helps to conserve power and increase battery life.
