Method And System For Location Of Objects Within A Specified Geographic Area
US Patent:
2007018, Aug 9, 2007
Filed:
Jan 12, 2007
Appl. No.:
11/652779
Inventors:
David Johnson - Escondido CA, US
Thomas La Rovere - Santa Barbara CA, US
Larry Weaver - Santa Barbara CA, US
Bruce Bivans - Goleta CA, US

Larry Weaver - Santa Barbara CA, US
Bruce Bivans - Goleta CA, US
International Classification:
H04Q 7/20
US Classification:
455456100
Abstract:
A method and system for determining the location of objects within a geographic area is disclosed. In one embodiment, the system includes a plurality of portable transceiver devices each coupled to a respective object located within the geographic area; a plurality of stationary transceiver devices fixed at predetermined locations within the geographic area, wherein the plurality of stationary transceiver devices are each configured to determine received signal strength (RSSI) values of signals transmitted by the plurality of portable transceiver devices; and a base station, comprising a base station transceiver device and a computer coupled to the base station transceiver device, wherein the base station is configured to receive RSSI values from at least one of the plurality of stationary transceiver devices and calculate a location of at least one portable transceiver device based on the received RSSI values.

Elastomeric Article With Fine Colloidal Silica Surface Treatment, And Its Preparation
US Patent:
7582343, Sep 1, 2009
Filed:
Jun 15, 1999
Appl. No.:
09/334054
Inventors:
David W. Johnson - Escondido CA, US
International Classification:
B28B 23/00
US Classification:
428 364, 428 357, 428145, 428149, 2167, 2168, 21617
Abstract:
A surface-modified article is formed of an elastomeric matrix, such as a glove shape, and a plurality of fine silica particles affixed to at least a portion of the surface of the matrix, the outside surface in the case of the glove. The fine silica particles increase the coefficient of friction of the article surface. The fine silica particles may also be made electrically conductive, so that static charge at the surface of the article is dissipated. The silica particles are applied by mixing them into a coating composition, applying the coating composition to the surface of a mold, and solidifying a flowable elastomeric composition against the coated surface. The coating composition may include a coagulant or a parting agent.

International Classification:
B32B001/02
US Classification:
428/035700
Abstract:
Disclosed is an elastomeric article, such as a glove, that includes a lubricant composition provided on an interior, wearer-contacting surface of the article, where the lubricant composition includes a wettable additive, such as a quaternary ammonium compound that includes an alkyl chain of at least 20 carbon atoms, and a silicone.
Unattended Replacement Of Plotter Pens
Unattended Replacement Of Plotter Pens
US Patent:
4920357, Apr 24, 1990
Filed:
Jun 29, 1989
Appl. No.:
7/373415
Inventors:
David A. Johnson - Escondido CA
Assignee:
Hewlett-Packard Company - Palo Alto CA
International Classification:
G01D 930
US Classification:
346 49
Abstract:
A computer driven plotter pen includes a turret from which a any one of plurality of different types of pens may be selected. When the plotter determines that a pen has become spent, the spent pen is automatically removed by a pen transfer carriage from the pen turret and discarded. The transfer carriage then removes a fresh replacement pen of like type to the spent discarded pen from a magazine thereof, and installs the replacement pen in the turret which in turn installs it in the plotter pen carriage. No operator involvement is required.
