US Patent:

7432991, Oct 7, 2008
Filed:

Oct 1, 2003
Appl. No.:

10/677393
Inventors:

Darwin Chang - Cupertino CA, US
Hing S. Tong - Saratoga CA, US
International Classification:

H04N 5/66
US Classification:

348739, 345 81, 345 98, 345 55
Abstract:

A digital display panel accepts pixel information according to their row-column coordinates. Each pixel can be individually written and read back, much like a random access memory (RAM). A pixel array self-refreshes, and can retain and display each image frame long after the original writing, like a dynamic random access memory (DRAM). Each pixel is instrumented with a transducer to sense pressure, temperature, light, strain, etc. , and provide sensor read-out data that is addressable by row-column coordinates. Such is very useful in touchscreen applications. The transducers and their corresponding pixels each have a special relationship, the transducers can directly manipulate a visual quality of the pixel through a direct connection, without intervention or assistance by a host processor.

US Patent:

20100292861, Nov 18, 2010
Filed:

May 18, 2009
Appl. No.:

12/454374
Inventors:

Leonard Tsai - Santa Clara CA, US
Darwin Chang - Cupertino CA, US
Hing S. Tong - Saratoga CA, US
International Classification:

G06F 1/32
G06F 1/26
US Classification:

700296, 700 3
Abstract:

A method for network energy controller that can optimize total system power consumption is provided. The controller () collected device loads and report to a common device () for optimization. The controller is able to communicate both to other controllers on the same power source or to the internal device () that is connected to the controller. The common device is able to respond to power changes reported by controller and request other controller to reduce power so that the entire system power consumption can meet or optimized toward the power policy goal.

Filed:

Feb 1, 2012
Appl. No.:

13/363669
Inventors:

Darwin Chang - Cupertino CA, US
Hing S. Tong - Saratoga CA, US
International Classification:

F24C 15/00
US Classification:

126 21 A
Abstract:

A high temperature convection fan device that improves the operation of an oven is provided. Each oven convection fan device component is designed to withstand the harsh environment and elevated temperatures common to an oven. Sources of energy include but are not limited to wind-up springs and/or drawing electric power from the oven lamp socket. Other solutions provide additional features including but not limited to lighting, sensors, control systems and/or displays.

Filed:

Nov 3, 1995
Appl. No.:

8/552803
Inventors:

Philip K. Siu - Los Altos Hills CA
Lawrence K. Lo - Los Altos Hills CA
Hing S. Tong - Saratoga CA
International Classification:

G11C 700
