Portable computer with a power control function
First Claim
1. A portable computer with a power control function comprising:
- a hinge having a first part and a second part pivotally coupled to the first part;
a first body affixed to the first part of the hinge;
a second body affixed to the second part of the hinge and rotatable with the second part of the hinge relative to the first body;
an optical sensor mounted on the first body, the optical sensor having transmitter means and receiver means, the transmitter means being adapted to emit a beam to the receiver means;
an optical grating connected to the second part of the hinge and rotatable with the second part of the hinge relative to the first part, the optical grating having a plurality of openings and a plurality of blocking zones, the optical grating having at least one part located between the transmitter means and the receiver means such that the optical sensor generates a first sensing voltage when one of the blocking zones blocks the beam from the receiver means, the optical sensor generating a second sensing voltage when the beam passes through one of the openings to the receiver means; and
a control circuit electrically connected to the optical sensor and adapted to generate a plurality of control signals including a first control signal for controlling the operation of an electronic component being electrically connected to the control circuit subject to the first sensing voltage and second sensing voltage provided by the optical sensor.

Abstract
A portable computer with a power control function is disclosed to include a first body, a hinge, a second body coupled to the first body through the hinge, an optical sensor having a transmitter and a receiver and mounted on the first body, an optical grating connected to the hinge and having a part located between the transmitter and the receiver, a control circuit, and an electronic component. When the second body is turned relative to the first body, the optical sensor generates a first sensing voltage and a second sensing voltage subject to the turning action of the optical grating so that the control circuit controls the power of the electronic component based on the first sensing voltage and the second sensing voltage provided by the optical sensor.
