Patent Images
1. An interface module comprising:
- a host-computer connector for physically and electrically connecting to a host computer;
an external-device connector for electrical communication with an external device;
interface circuitry to manage communications between said host computer and said external device via said connectors;
a power sensor for providing digital data indicating power consumed by said interface module; and
a power tracker for time stamping and storing said digital data.

Abstract
An interface module for interfacing an external device with a host computer is physically and electrically connected to the host computer. The module monitors its own power consumption and reports its power consumption to the host computer. This information can be used to determine the total power consumed by multiple modules, to indicate a problem with the interface module, or to detect a leakage current associated with the external device when main power is off.

6. A method comprising:
-
generating digital data representing power consumption by an interface module for interfacing an external device with a host computer;
time-stamping said digital data to yield time-stamped data; and
transferring said time-stamped data to said host computer. - View Dependent Claims (7, 8, 10, 13)

15. A method comprising:
-
supplying main power to an interface module of a computer;
monitoring power consumption by said interface module after said main power is withheld from said interface module to determine whether or not a leakage current is present;
in the event said leakage current is not detected, performing a hot swap of said interface module; and
in the event said leakage current is detected, performing a cold swap of said interface module. - View Dependent Claims (16, 17)
