Thermal management apparatus based on a power supply output
First Claim
1. A thermal management apparatus, comprising:
- a detection circuit adapted to generate a first signal indicating an amount of power transferred to a device; and
a control circuit, coupled to the detection circuit, adapted to generate at least one control signal to indicate a thermal condition of the device and to effect a power management action based on the first signal.

Abstract
A power management apparatus includes a power source, a detection circuit to generate a first signal indicating the power transferred to a portion of a computer system from the power source, and a control circuit to generate at least one control signal to effect a power management action based on the first signal. A program storage device (readable by a programmable control device) includes instructions to manage power in a computer system. The program storage device includes instructions to receive a power signal from a power source (the power signal furnishing power to a portion of the computer system), generate a first signal indicating the power transferred from the power source to the portion of the computer system, and generate a second signal to effect a power management action based on the first signal.

20. A thermal management apparatus, comprising:
-
a power source to produce a power signal, wherein the power signal is a pulse width modulated signal indicating an amount of power furnished to a portion of a computer system; and
a control circuit to effect a power management action, wherein the control circuit receives a representation of a duty cycle of the pulse width modulated signal and generates a second signal based on a state of the representation. - View Dependent Claims (21, 22, 23, 24)
