Filed:

Dec 7, 2000

Appl. No.:

09/730534

Inventors:

Wayne A. Pittman - Milpitas CA
David P. Swartz - San Jose CA

Assignee:

Sensotec, Inc. - Columbus OH

International Classification:

H02H 300

US Classification:

361 42, 361 20, 361 23, 361 44

Abstract:

The new Ground Fault Detection and Diode Fault Detection (GFD/DFD) Systems have rotating and stationary component assemblies. The rotating assembly has four interface modules, which are normally encapsulated, in a specially configured support ring. The GFD/DFD Systems support ring assembly is bolted to the brushless exciter. The brushless exciter is attached to a generator or motor. The GFD/DFD System support ring is provided power by an induction loop antenna attached to a stationary Induction Power Supply (IPS). A Receiver Control Unit provides power to the IPS and receives and conditions the RF (radio frequencies) data transmitted from the GFD/DFD System support ring assembly. These units together provide the means to detect ground faults, to detect diode faults, and to activate alarm lights and electrical control signals for normal and faulty operating conditions.

Abstract:

A camera system includes a processor, a camera coupled to the processor, a display coupled to the processor, and a memory storing instructions that, when executed by the processor, cause the processor to store a first image in the memory, modify the first image to generate a modified first image, the modified first image corresponding to the first image at a reduced opacity, control the camera to capture a real-time preview, overlay the modified first image on the real-time preview to generate a combined preview, output the combined preview to the display, capture a second image using the camera, and store the second image in the memory.
