Optical Displacement Sensor Utilizing Optical Diffusion
US Patent:
5376785, Dec 27, 1994
Filed:
Oct 2, 1992
Appl. No.:
7/955932
Inventors:
Philip K. Chin - Metairie LA
P. Michael Lynch - New Orleans LA
P. Michael Lynch - New Orleans LA
International Classification:
H01J 314
US Classification:
250214PR
Abstract:
An optical displacement sensor is disclosed for use in robotic applications. The sensor can be used to examine the shape and surface texture of an object. In the embodiment which includes a compressible means of known spring constant, the sensor can be used to measure contract force. The position sensor uses an electro-optical displacement transducer to convert a displacement into an electrical output. The sensor utilizes a phototransistor to measure light emitted by an infrared light emitting diode. The amount of light received from by the phototransistor is varied by the displacement of the contact probe, or shadow rod.
Method Of Displaying Data In A Table
US Patent:
2006011, Jun 1, 2006
Filed:
Nov 21, 2005
Appl. No.:
11/284942
Inventors:
Philip Chin - Metairie LA, US
International Classification:
G06F 7/00
US Classification:
707101000
Abstract:
A method and computer-executable program code for displaying data in a table having columns, rows and a plurality of cells defined by the columns and rows. The method involves the steps of creating a first and a second sub-tables positioned one above another or side-by-side. The top sub-table defines a non-scrollable, fixed header, while the bottom table defines a scrollable data table. The top table has a visible part and a hidden part, which contains records copied from a maximum width cell in the top or bottom table corresponding to each individual column. To form a fixed sidebar, the code computer-executable program code adjusts the height of the rows based on the parameters of a maximum height cell in the row.

Reflection Shadow Sensor With Light Directing Diffusive Surface
US Patent:
5532473, Jul 2, 1996
Filed:
Oct 20, 1994
Appl. No.:
8/326652
Inventors:
Philip K. Chin - Metairie LA
International Classification:
H01J 314
US Classification:
250214PR
Abstract:
A reflective shadow sensor is disclosed for use in detecting the position of a moving object by directing a flow of light towards that object and detecting the amount of light reflected by a surface of the moving object.
Optical Displacement Sensor Utilizing Optical Diffusion And Reflection
US Patent:
5389777, Feb 14, 1995
Filed:
Jul 30, 1993
Appl. No.:
8/100488
Inventors:
Philip K. Chin - Metairie LA
International Classification:
H01J 4014
US Classification:
250214PR
Abstract:
The invention relates to optical devices, particularly to an optical displacement transducer for detecting a light flow received by a light sensor and subsequent determination of the amount of force applied to an object within which the optical displacement transducer is mounted. The transducer utilizes a light source which is mounted within a housing having a translucent face, and a light sensor mounted in a body having a corresponding translucent face. The light flow which travels between the translucent faces is intermittently blocked by a shadow rod moving between the light source and the light sensor in response to an external force applied to the shadow rod.
