Apparatus and method for measuring power usage in a wireless mobile station
First Claim
1. For use in an electronic device capable of operating in a low power mode from a removable battery module, a power monitoring device comprising:
- a module capable of being attached to said electronic device in place of said battery module, said module having first battery contacts thereon capable of interfacing with second battery contacts disposed in said electronic device;
power supply circuitry disposed in said module capable of providing to said first battery contacts a first supply voltage substantially similar to a voltage level provided by said removable battery module, wherein attachment of said module causes said electronic device to detect said first supply voltage and enables said electronic device to operate in said low power mode; and
power measurement circuitry disposed in said module capable of measuring a power level supplied by said power supply circuitry to said electronic device.

Abstract
A power monitoring device for use in an electronic device that operates in a low power mode from a removable battery module. The power monitoring device comprises a module that attaches to the electronic device in place of the battery module. The module has first battery contacts for interfacing with second battery contacts disposed in the electronic device. Attachment of the module causes the electronic device to operate in the low power mode. The power monitoring devices also comprises power supply circuitry for providing a supply voltage substantially similar to a voltage level provided by the removable battery module, and power measurement circuitry for measuring a power level supplied by the power supply circuitry.

16. A method of monitoring power consumption of an electronic device capable of operating in a low power mode from a removable battery module, the method comprising the steps of:
-
attaching a power monitor module to the electronic device in place of the battery module, wherein the power monitor module has first battery contacts thereon capable of interfacing with second battery contacts disposed in the electronic device;
in the power monitor module, providing to the first battery contacts a first supply voltage substantially similar to a voltage level provided by the removable battery module, wherein attachment of the power monitor module causes the electronic device to detect the first supply voltage and enables the electronic device to operate in the low power mode; and
in the power monitor module, measuring a power level supplied by the power supply circuitry to the electronic device. - View Dependent Claims (17, 18, 19, 20, 21, 22)
