Light Sensing System With High Pixel Fill Factor

View page
US Patent:
6486522, Nov 26, 2002
Filed:
Sep 28, 1999
Appl. No.:
09/407741
Inventors:
Magued Bishay - Costa Mesa CA
Randall M. Chung - Laguna Niguel CA
James K. Dawson - Huntington Beach CA
David Escobar - San Juan Capistrano CA
Mike Fukatsu - La Mirada CA
Edward Andrew Jakl - Tustin CA
Richard Arthur Mann - Torrance CA
Sarit Neter - Irvine CA
Ian Olsen - Irvine CA
Gregory A. Urban - Las Flores CA
Assignee:
Pictos Technologies, Inc. - Newport Beach CA
International Classification:
H01L 3100
US Classification:
257444, 257431
Abstract:
The invention is an imaging device having a high fill factor. The high fill factor is achieved by constructing the light sensors in a vertical fashion in the imaging device. The control circuitry of the light sensor is then contained inside the integrated circuit chip, rather than taking up area that could otherwise be used for light collection. The majority of the area on the surface of the IC chip is made up of light sensing elements, since the control circuitry is embedded in the IC chip. The control circuitry is connected to the light sensing devices through vias in the IC chip. The control circuitry of the chip is mainly contained within the die, rather than on it.

The optics unit may be either electrically active or passive. When active, the optics unit is coupled to the integrated circuit with a conductor. The optics unit may also include a liquid crystal device, a beamsplitter assembly, a lensing assembly or other filters, and/or apertures. The liquid crystal device can act as a shutter or a display and the optics unit may be a single module or a plurality of modules. The integrated circuit may also include shutter drive circuitry and image processing circuitry.

Real Time Camera Exposure Control

View page
US Patent:
6677996, Jan 13, 2004
Filed:
Apr 21, 1999
Appl. No.:
09/295699
Inventors:
Randall M. Chung - Laguna Niguel CA
Paul K. Kim - Torrance CA
Wei Feng - Irvine CA
Assignee:
Pictos Technologies, Inc. - Newport Beach CA
International Classification:
H04N 314
US Classification:
348308, 348301, 348241, 2502081
Abstract:
The present invention discloses an electronic camera which processes the exposure of light by means of an imaging surface comprising a plurality of active pixel sensor circuits. Each pixel sensor circuit produces a small current inversely proportional to the amount of light that has fallen on a photodiode within the pixel sensor circuit. The individual currents produced by the active pixel sensor circuits are aggregated onto one or more current collection busses and operatively channeled to an operational amplifier assigned to a given bus. If a single operational amplifier is used, its output voltage is compared to a preset voltage level. When the voltage level decays to a preset level, a control signal is signaled. The control signal may be used to terminate further light exposure through traditional means such as triggering a âsnubberâ tube which immediately discharges the flash tube storage capacitor or turning off an IGBT high power transistor controlling the current through the flash tube, or, it may trigger an electronic shutter which prevents further photographic development of the imaging surface. Through the use of multiple operational amplifiers, different sectors of the imaging surface can be âweighted,â thereby giving greater effect to the light falling on select portions of the imaging surface.

Combined Single-Ended And Differential Signaling Interface

View page
US Patent:
6836290, Dec 28, 2004
Filed:
Apr 29, 1999
Appl. No.:
09/302090
Inventors:
Randall M. Chung - Laguna Hills CA
Ferry Gunawan - Santa Ana CA
Dino D. Trotta - Costa Mesa CA
Assignee:
Conexant Systems, Inc. - Newport Beach CA
International Classification:
H04N 314
US Classification:
348294, 326 81, 327 52, 375219, 375316
Abstract:
A data interface for CMOS imagers is disclosed that can be either a single-ended interface or a differential interface. The single-ended interface provides compatibility with many existing external devices. Further providing a differential interface allows a lower noise and a lower power interface for external devices that can support a differential signal. The combined single-ended and differential signal interface does not increase the number of pins required for a single-ended only interface. The data transfer width is set to the word width, which allows a fixed timing relationship between the clock edge and data transfer in both single-ended and differential modes. In single-ended mode, the data is transferred once per clock, but in the differential mode, the data is transferred twice per clock, once on each clock edge. This fixed timing relationship eliminates the need for and cost of explicit bit synchronization.

Infrared Communication System Utilizing Receiver With Multiple Photo-Sensors

View page
US Patent:
7039326, May 2, 2006
Filed:
Sep 29, 1999
Appl. No.:
09/408198
Inventors:
Randall M. Chung - Laguna Niguel CA, US
Assignee:
ESS Technology, Inc. - Fremont CA
International Classification:
H04B 10/06
US Classification:
398202, 2502082, 398208, 398212
Abstract:
A communication system including an infrared receiver that receives optical infrared signals. The infrared receiver utilizes an array of photo-sensors for detecting optical infrared signals within a solid angle. Each photo-sensor, however, detects optical infrared signals in only a predetermined portion of the solid angle. On detecting optical infrared signals, each photo-sensor converts and forwards a corresponding electrical signal to a filter circuit that selectively determines whether the signal meets a predetermined criteria such as a frequency threshold. The filter circuit or other processing circuitry is thereby able to identify photo-sensor(s) providing an optimal infrared communication link. The infrared receiver may include an optical system comprising a lens assembly that directs the optical infrared signals towards the array of photo-sensors. In one embodiment, the lens assembly employs a diffused lens having an imperfect focus to facilitate the detection of optical infrared signals emanating from transmitters that have a relatively small solid angle.

Splitting And Redundant Storage On Multiple Servers

View page
US Patent:
20040088380, May 6, 2004
Filed:
Sep 12, 2003
Appl. No.:
10/471849
Inventors:
Randall Chung - Laguna Niguel CA, US
Maged Bishay - Costa Mesa CA, US
Michael Zelevinsky - San Diego CA, US
Sivagnanam Parthasarathy - Carlsbad CA, US
International Classification:
G06F015/16
US Classification:
709/219000
Abstract:
One aspect of the invention involves dividing a single file (300) into multiple sub-files (310, 320, 330, 340) that are subsequently distributed and stored onto one or more servers. The sub-files (310, 320, 330, 340) may be transmitted in parallel and simultaneously from one or more servers, which increases the rate at which the data can be delivered. A second aspect of the invention involves storing at least one of the sub-files (310, 320, 330, 340) on more than one server to provide redundancy. If one server is not available, or if the transmission link is slow or not available, the sub-file can be streamed from another server. In one embodiment, each end user may receive multiple sub-files simultaneously from multiple servers. Disk input/output bandwidth is saved because only the necessary fraction of data needs to be read from each server.

Filed:
Aug 31, 2009
Appl. No.:
12/550992
Inventors:
Randall M. Chung - Laguna Niguel CA, US
International Classification:
H02K 7/18
US Classification:
290 1 R
Abstract:
A refrigeration unit or system is used to at least partially freeze water. The at least partially frozen water may then be separated into ice and water. The ice may be stored and allowed to melt, thereby providing an ice portion and a melted ice water portion. When energy release is desired, the melted ice water portion along with a hot liquid may be used to drive a thermal motor. The thermal motor may then in turn drive the electric generator, resulting in electric energy production.
