US Patent:

20120069143, Mar 22, 2012

Filed:

Sep 20, 2010

Appl. No.:

12/886503

Inventors:

Joseph Yao Hua Chu - San Jose CA, US

International Classification:

H04N 13/00

US Classification:

348 43, 348E13001

Abstract:

A technique for tracking and highlighting an object in stereoscopic images by changing the depth of the object is disclosed. A stereoscopic image is processed using an object detection algorithm to select the pixels associated with the object in the image. The depth of the object is adjusted in the stereoscopic image by adjusting the disparity between the pixels associated with the object in the left and right stereoscopic image pair. The processed stereoscopic image is then displayed on a stereoscopic display or stored in memory. An object is tracked by highlighting the object in consecutive stereoscopic images that depict the object.

H02J 7/00

US Classification:

348372, 320114, 3482071

Abstract:

One embodiment of the present invention sets forth a digital camera configured to be powered by rechargeable nickel-metal hydride (NiMH) batteries. The digital camera includes one or more rechargeable NiMH batteries, and first internal circuitry configured to receive power from a universal serial bus (USB) port associated with an external power source and to charge the rechargeable NiMH batteries without removing the rechargeable NiMH batteries from the digital camera.

Appl. No.:

16/758639

Inventors:

- Osterville MA, US
Joseph Yoa Hua Chu - Los Gatos CA, US

International Classification:

F21S 9/02
F21V 23/04
H02J 50/05

Abstract:

The present disclosure provides intelligent lighting control systems. The lighting control system apparatuses include a light control module configured to be coupled to a luminaire electrically coupled to a light bulb comprising a capacitor. The lighting control module comprises a controller configured to temporarily close a circuit comprising a load wire configured to connect an AC power source to the capacitor through the luminaire, whereby electricity flowing through the load wire flows through the capacitor in the light bulb and charges an energy storage device in the lighting control module electrically coupled to the load wire. The controller is configured to after temporarily closing the circuit, re-open the circuit prior to the capacitor fully charging, so as to prevent a light emitting element of the light bulb electrically coupled to the capacitor from illuminating.

International Classification:

H05B 45/24
H05B 45/385
H05B 45/10
H05B 45/325

Abstract:

The present disclosure provides intelligent lighting control systems. The light control systems include light bulb apparatuses including a receiver for receiving an encoded alternating current (AC) power signal transmitted from a lighting control system to a luminaire electrically coupled to the light bulb apparatuses, a signal transformer for converting an input signal, a light emitting element coupled to the signal transformer, and a controller communicably coupled to the signal transformer.
