First Claim
Patent Images
1. A wireless receiver configured to receive a directional signal, the receiver having a standby mode in which at least an oscillator of the receiver is deenergized and a DC detect circuit detecting an incoming directional signal, the DC detect circuit causing at least the oscillator of the receiver to be energized.

Abstract
A wireless receiver of a directional signal such as a 60 GHz signal can have a low power standby mode in which the linear oscillator (radio) portion of the receiver is deenergized. A DC detect circuit can detect the DC portion of an incoming signal, at which time the DC detect circuit energizes the remaining portions of the receiver.

10. A receiver, comprising:
-
an AC signal receiver;
means for deriving, from an incoming directional AC signal, a DC signal; and
means for causing the AC signal receiver to be energized when the DC signal satisfies a threshold. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method for conserving power in a receiver, comprising:
-
receiving a directional AC signal;
deriving a DC signal from the AC signal;
if the DC signal satisfies at least one criterion, energizing an AC signal receiver and sending the AC signal thereto, otherwise maintaining the AC signal receiver in a standby state wherein at least portions of the receiver are deenergized. - View Dependent Claims (18, 19)
