Beam Scanning Based On Two-Dimensional Polygon Scanner For Display And Other Applications
US Patent:
2010002, Jan 28, 2010
Filed:
Jul 25, 2008
Appl. No.:
12/180114
Inventors:
Bruce Borchers - Scotts Valley CA, US
Roger A. Hajjar - San Jose CA, US
Roger A. Hajjar - San Jose CA, US
Assignee:
SPUDNIK, INC. - San Jose CA
International Classification:
G02B 26/12
US Classification:
3592161
Abstract:
Scanning beam systems based on a two-dimensional polygon scanner with different reflective polygon facets tilted at different tilt facet angles to use rotations of the polygon scanner to scan optical beams both horizontally and vertically on a surface which can be a display screen or a printing surface.
Geometric Feature Driven Flow Equalization In Fuel Cell Stack Gas Flow Separator
US Patent:
2006020, Sep 14, 2006
Filed:
Mar 9, 2005
Appl. No.:
11/076102
Inventors:
Bruce Borchers - Santa Cruz CA, US
International Classification:
H01M 8/02
US Classification:
429038000, 429013000
Abstract:
A gas flow separator for a fuel cell stack includes a plurality of gas flow channels and a gas flow restrictor located in each channel. Each gas flow restrictor may be a geometric feature which restricts gas flow in each respective channel.

US Patent:
8593711, Nov 26, 2013
Filed:
Jul 27, 2009
Appl. No.:
12/812188
Inventors:
Bruce Borchers - Scotts Valley CA, US

Roger A. Hajjar - San Jose CA, US
Assignee:
Prysm, Inc. - San Jose CA
International Classification:
G02B 26/08
US Classification:
3592192
Abstract:
Scanning beam systems based on a two-dimensional polygon scanner with different reflective polygon facets tilted at different tilt facet angles to use rotations of the polygon scanner to scan one or more optical beams both horizontally and vertically on a surface which can be a display screen or a printing surface.
Optical Beam Control Based On Flexure Actuation With Positioning Sensing And Servo Control
US Patent:
8274724, Sep 25, 2012
Filed:
Sep 23, 2011
Appl. No.:
13/243731
Inventors:
Bruce Borchers - Scotts Valley CA, US
Robert Stark - Saratoga CA, US
Robert Stark - Saratoga CA, US
Assignee:
Prysm, Inc. - San Jose CA
International Classification:
G02B 26/08
US Classification:
3592241, 3591993, 3592007
Abstract:
Implementations of actuators that use flexures to provide support to actuators and pivoting mechanisms to the actuators. Such actuators can be electromagnetically activated actuators that include a magnet stator and a coil rotor mounted on a flexure. A positioning sensor, such as a capacitor sensor, is provided to measure and monitor positioning of the actuator and is coupled to a feedback circuit which uses the measured positioning of the actuator to control the actuator.
Precision Molded Flexure Assembly For A Rotational Actuator
US Patent:
2013008, Apr 11, 2013
Filed:
Oct 11, 2011
Appl. No.:
13/271075
Inventors:
Bruce A. BORCHERS - Scotts Valley CA, US
International Classification:
H02K 11/00, B29C 45/14, F16M 13/00
US Classification:
310 38, 248560, 264261
Abstract:
A flexure assembly includes two metallic flexure arrays molded into a thermoplastic support base. The two flexure arrays are positioned in parallel in the thermoplastic support base to allow rotational movement about one axis while providing high stiffness with respect to off-axis movement. Flexible supports in the two flexure arrays may be interleaved to form a cross flexure configuration. Off-axis stiffness of the flexure assembly prevents harmonic resonance in directions that cannot be compensated for in a single-axis actuator.
Thermal Conduction Path For A Heat-Sensitive Component
US Patent:
2013004, Feb 21, 2013
Filed:
Aug 16, 2011

John M. Watson - Haverhill MA, US
International Classification:
H01S 3/04, B23K 1/20
US Classification:
372 34, 228249
Abstract:
A thermal conduction path for a heat-sensitive, heat-generating component is formed by placing a heat-generating device, such as a laser diode, in a desired orientation relative to a supporting surface. A solid-phase mass of a heat-conducting material is positioned between the heat-generating device and the supporting surface and is converted to liquid phase by heating the supporting surface. Additional heat-conducting material is then added to the liquid-phase heat-conducting material until a meniscus is formed between the heat-generating component and the supporting surface. Because the heat-conducting material has a melting point or liquidus that is less than a critical temperature of the heat-generating component, the thermal conduction path can be formed without damaging the heat-generating component.
Positioning Sensing And Position Servo Control
US Patent:
2013002, Jan 24, 2013

International Classification:
G05B 1/06
US Classification:

Abstract:
Implementations of actuators and capacitor-based position sensors for monitoring and controlling positioning of the actuators are provided, including implementations of actuators that use flexures to provide support to actuators and pivoting mechanisms to the actuators. Such actuators can be electromagnetically activated actuators that include a magnet stator and a coil rotor mounted on a flexure. A positioning sensor, such as a capacitor sensor, is provided to measure and monitor positioning of the actuator and is coupled to a feedback circuit which uses the measured positioning of the actuator to control the actuator.
