Eric Peeters, Decai Sun, G A Neville Connell, Ross D Bringans, Raj B Apte, Thomas L Paoli, Patrick Y Maeda, David K Fork, Joel A Kubby, Philip D Floyd: Monolithic scanning light emitting devices using micromachining. Xerox Corporation, David E Henn, January 30, 2001: US06180428 (194 worldwide citation)

A micro-machined movable light emitting assembly is formed on or from an undoped or pure III-V substrate or formed on or from a doped III-V substrate. The movable light emitting assemblies are to be actuated using force generators, to generate the various mechanical degrees of freedom depending on t ...

Seamed belts having puzzle-cut seam with edges that are themselves puzzle-cut: puzzle-cut on puzzle-cut seamed belts. Such belts beneficially may take the form of imageable seam intermediate transfer belts such as those used in marking machines. Belts are formed from a substrate having a puzzle-cut ...

Jingkuang Chen, Joel A Kubby, Decai Sun: Micro-opto-electro-mechanical system (MOEMS). Xerox Corporation, David E Henn, June 17, 2003: US06580858 (39 worldwide citation)

A MEMS-based adjustable mirror module allows faster, lower cost, and easier alignment of optical fibers in substrates. Movable mirrors formed on the substrate allow adjustment of the light path after the optical fiber is attached, after which the mirrors are affixed in place to prevent misalignment.

Jingkuang Chen, Joel A Kubby: Monolithic spectrophotometer. Xerox Corporation, Robert A Burtzlaff, David E Henn, June 19, 2001: US06249346 (36 worldwide citation)

A micro spectrophotometer is monolithically constructed on a silicon substrate. The spectrophotometer includes a concave grating, which is used for dispersing optical waves as well as focusing reflected light onto a photodiode array sited on a silicon bridge. The silicon bridge is bent 90° from the ...

Mark H Yim: Fault tolerant connection system for transiently connectable modular elements. Xerox Corporation, Robert A Burtalaff, David E Henn, May 15, 2001: US06233502 (35 worldwide citation)

A system and method for transiently connecting modular elements of a self movable robot. The self movable robot is known as metamorphosing robots, polymorphic robots, shape changing robots, or morphable structures. The modular elements can act together to build a structure to perform a given task. E ...

Jerry F Adams: Printer fuser heater controller with power factor correction. Xerox Corporation, John M Kelly, David E Henn, November 13, 2001: US06317571 (13 worldwide citation)

Power factor control in an AC powered machine having multiple input electrical power requirements. AC input power is continuously applied to a low input power load and selectively to a high input power load. The AC power to the high input power load is pulse modulated to have an input power that dep ...
