Patent number: 9235006Abstract: Described herein is an optical channel monitor (100), including a plurality of input ports in the form of optical fibers (102) disposed in a vertical “port displacement” dimension. Each fiber (102) inputs a respective optical beam (103) having a plurality of individual wavelength channels. A lens (104) collimates each beam and converges the beams in the port displacement dimension to a focal plane (105). The collimated and converged beams are incident onto a rotatable micro-electromechanical system (MEMS) mirror (106), which selectively directs each optical beam onto a wavelength dispersion element in the form of a grism (108) at a predetermined angle (denoted by ?) in a horizontal “dispersion” plane. The grism (108) spatially separates, in the dispersion plane, the wavelength channels contained within each optical beam (103) by diffraction. The angle at which each channel is diffracted is controlled by the angle ?.Type: GrantFiled: May 1, 2012Date of Patent: January 12, 2016Assignee: Finisar CorporationInventors: Steven James Frisken, Dmitri Abakoumov

Patent number: 9235045Abstract: Image projection illumination apparatus and methods are provided. A color wheel has a blue laser light reflecting region and other regions respectively coated with different color light emitting phosphors. Blue laser light of a given polarization is directed by reflection or transmission by a blue laser light polarization selective filter through a polarization changing element with changed polarization onto the color wheel. When the color wheel reflecting region is aligned with the incident light, incident light is reflected back through the polarization changing element with further changed polarization by the other of reflection or transmission by the filter for image projection. When the other regions are respectively aligned with the incident light, the different color light is emitted by the phosphors along the light path for image projection.Type: GrantFiled: January 16, 2014Date of Patent: January 12, 2016Assignee: TEXAS INSTRUMENTS INCORPORATEDInventor: Sajjad Ali Khan

Patent number: 9235046Abstract: This disclosure provides systems, methods and apparatus for providing relatively thinner and less stiff compliant beams for a shutter assembly. A protective coating is deposited and patterned over the shutter assembly before it is released from a sacrificial mold over which the shutter assembly is formed. Because some primary surfaces of the compliant beams are in contact with the sacrificial mold, these primary surfaces are not coated with the protective coating. Therefore, when the shutter assembly is finally released, the resulting compliant beams are relatively thinner and less stiff providing a reduction in an actuation voltage used to operate the shutter assembly. In some instances, the protective coating is patterned into discontinuous segments before release.Type: GrantFiled: January 30, 2013Date of Patent: January 12, 2016Assignee: Pixtronix, Inc.Inventors: Javier Villarreal, Timothy J. Brosnihan, Jasper L. Steyn, Richard S. Payne, Stephen R. Lewis

Patent number: 9235047Abstract: This disclosure provides novel latching circuits, and pixel circuits and display devices that include such latching circuits. The latches herein include a switch positioned on an inverter coupling interconnect which couples two cross-coupled inverters of the latch. The switch is configured to control a passage of a current between the first and second inverters. By switching the switch OFF at a time a data voltage is transferred to the inverters, any leak current between the inverters can be interrupted. As a result, a malfunctioning of the data latch is prevented.Type: GrantFiled: May 30, 2012Date of Patent: January 12, 2016Assignee: Pixtronix, Inc.Inventors: Mitsuhide Miyamoto, Katsumi Matsumoto, Takahide Kuranaga

Patent number: 9235049Abstract: A lens includes a depth of field (“DOF”) range and a macro range. The macro range is distinct and separate from the DOF range. The macro range is a near field relative to the DOF range. The DOF range provides a first field of view (“FOV”) while the macro range provides a second FOV that is smaller than the first FOV within the DOF range. The lens transfers sharpness from a peripheral viewing region within the macro range into a central viewing region within the macro range.Type: GrantFiled: May 19, 2015Date of Patent: January 12, 2016Assignee: Google Inc.Inventors: Xiaoyu Miao, Hayes S.

Patent number: 9235050Abstract: A light guide plate receives light emitted from the light source, and emits the light from a light emitting surface. A prism sheet reflects light at a predetermined angle among the light emitted from the light emitting surface, allows the reflected light to enter the light guide plate, and transmits light at another angle. A polarization control element is provided between a 1/4 wavelength plate and a reflection-type liquid crystal display element so as to be parallel to the light emitting surface. The polarization control element splits the light emitted from the 1/4 wavelength plate into first polarized light allowed to transmit as illumination light that enters the reflection-type liquid crystal display element and second polarized light reflected so as to enter the light guide plate, and reflects the light modulated and emitted by the reflection-type liquid crystal display element toward an imaging lens.Type: GrantFiled: August 19, 2014Date of Patent: January 12, 2016Assignee: JVC KENWOOD CORPORATIONInventor: Manabu Kobayashi

Patent number: 9235051Abstract: A see-through head mounted display apparatus includes a display and a processor. The processor determines geo-located positions of points of interest within a field of view and generates markers indicating information regarding an associated real world object is available to the user. Markers are rendered in the display relative to the geo-located position and the field of view of the user. When a user selects a marker though a user gesture, the device displays a near-field virtual object having a visual tether to the marker simultaneously with the marker. The user may interact with the marker to view, add or delete information associated with the point of interest.Type: GrantFiled: June 18, 2013Date of Patent: January 12, 2016Assignee: Microsoft Technology Licensing, LLCInventors: Tom G.
