1. An aberrant component detection method comprising:
- storing, in a computer memory, a reference current indicative of proper functioning of a particular component;
sensing current supplied to a group of components including the particular component;
comparing the current supplied to the group of components to the reference current; and
recording a result of comparing the current to the reference current.

Abstract
Current supplied to a group of components is selectively sensed so that the current supplied when a particular component is the only active component can be compared to a reference current indicative of proper component operation. If there is a discrepancy, an alert can be generated. Can be applied on a larger scale to allow isolation of a subsystem, then a group within the subsystem, then a component with the group, etc.

- 12. An aberrant component detection method comprising recording a result of comparing a sensed current to a reference current, the sensed current being supplied to a group of components including the particular component, the reference current being indicative of proper functioning of a particular component and being stored in a computer memory.

19. An aberrant component detection method comprising:
-
storing, in a computer memory, a reference current indicative of proper functioning of a particular component;
sensing current supplied to a group of components including the particular component while only the particular component draws current;
comparing the current supplied to the group of components to the reference current; and
recording a result of comparing the current to the reference current, wherein recording a result comprises at least one of storing the result in a computer memory, displaying an alert when there is a discrepancy between the reference current and the current supplied to the group of components, and recording the circuit to which current was supplied during sensing. - View Dependent Claims (20, 21)
