Computer user detection apparatus |
摘要 |
A new detection apparatus is disclosed, which has particular application for detecting the new presence or absence of a computer user. The absence of a user can trigger a computer display to power down, while the detected presence of a user can trigger the display to power back up, optionally requiring a log in. The detection apparatus operates fully automatically and so provides a reliable way of saving power and ensuring security of data.
