Patent number: 11947210Abstract: The present disclosure relates identifying an intended viewer and an unintended viewer of a liquid crystal display (LCD) using face recognition technology. Once identified the system may determine a face position for the unintended viewer. The system may modulate the voltage applied at a third electrode on the color filter layer of the LCD to achieve a certain off-axis contrast that may reduce the unintended viewer's visibility of the LCD without restricting the visibility of the intended viewer. Ultimately, the present disclosure provides enhanced privacy options for the intended viewer with a lightweight, inexpensive, and highly transportable system.Type: GrantFiled: May 4, 2023Date of Patent: April 2, 2024Assignee: Microsoft Technology Licensing, LLCInventors: Timothy A. Large, Neil Emerton, Sunando Sengupta

Publication number: 20210144313Abstract: Methods, systems and computer program products are provided for a logo camera. Camera thickness may be reduced using multiple lenses and sensors. A fixed or variable color icon may provide a function, notice or privacy warning, convey information, and/or serve decorative and/or other purposes. Color filters may be fixed or variable. A color icon may be created, for example, by controlling the colors of display pixels aligned with optical paths of camera lens and sensor arrays. Colors in an icon may provide color filters corresponding to an array of lenses that focus color-separated light on one or more camera sensors. Sensors may be optimized for particular colors. Color-separated images may be combined into a single image. Lens and camera sensor arrays may be compatible with multiple logos or other icon images. Cameras behind fixed or variable color icons may be concealed, for example, using shutters or semi-reflective layers.Type: ApplicationFiled: November 9, 2019Publication date: May 13, 2021Inventors: Timothy A.

Patent number: 10585230Abstract: Examples are disclosed that relate to backlit electronic displays that may help to avoid apparent non-uniform image brightness across a displayed image. One example provides an electronic display comprising a light guide, an image-forming layer, and a light-steering layer. The light guide is configured to release light over a display area. The image-forming layer is configured to form a display image by modulating the light released by the light guide. The light-steering layer is configured to steer together the light released from a peripheral region of the light guide and the light released from a central region of the light guide.Type: GrantFiled: March 23, 2016Date of Patent: March 10, 2020Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventor: Timothy A.

Publication number: 20170139500Abstract: A touch screen panel comprises an outer surface that defines a touch sensitive surface with a touch sensitive area. The outer surface comprises friction features distributed throughout at least a portion of the touch sensitive area according to one or more predetermined spacings. The friction features are configured to have predetermined friction characteristics that impart a desired tactile effect, e.g., a paper-like feel, to the touch sensitive surface when contacted by a user's finger or a stylus. Methods of forming a touch screen panel with predetermined friction features are also described.Type: ApplicationFiled: November 16, 2015Publication date: May 18, 2017Applicant: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Timothy A.

Patent number: 8031408Abstract: A fluid displacement mechanism is disclosed. In an embodiment, first and second cavities are separated by a flexible membrane. The first cavity contains a non-conductive fluid and the second cavity contains a conductive fluid. First and second electrodes are positioned in the first and second cavities respectively such that the application of a voltage between the electrodes causes movement of the membrane by the build up of an electrostatic charge between the membrane and first electrode.Type: GrantFiled: April 7, 2008Date of Patent: October 4, 2011Assignee: Microsoft CorporationInventor: Timothy A.

Publication number: 20100053771Abstract: A flat panel lens system as a tapered light guide that has minimal or no margin for fan out. The tapered light guide includes a thin end, and a thick end of which is a bevelled mirror or an optical equivalent. Light is injected into the thin end and the mirror is such that rays injected through a point at the thin end emerge collimated from one of the light guide surfaces, and that collimated rays injected at an appropriate angle through one of the light guide surfaces emerge from a point at the thin end. Bragg gratings can be utilized for color implementations as well. The tapered light guide can be fabricated as a single piece, by extrusion, injection molding, or the combination/variation of extrusion and injection molding, as well as other commonly known techniques.Type: ApplicationFiled: September 3, 2008Publication date: March 4, 2010Applicant: Microsoft CorporationInventors: Adrian Travis, Timothy A.

Patent number: 6373621Abstract: A method of operating Raman amplification pump lasers, especially in telecommunication systems, is described and claimed, in which the Raman pump laser output powers are modulated in characteristic fashions. Parameters of these characteristic modulations may be detected at remote locations (i.e. locations along the communications fibres) even in the presence of large amounts of noise. Thus, by detecting losses of signals indicative of the characteristic modulations, breaks in the communication fibres can be detected more reliably. The disappearance of these signals can then be used to shut down the typically high power Raman pump lasers, thereby reducing the possibility of high laser powers escaping from the broken fibres. The specification also described an improved method of detecting the disappearance of a data signal at an amplifier unit, using a periodic filter to split the incoming signal into two streams, the first stream comprising data and noise, and the second comprising noise only.Type: GrantFiled: January 18, 2001Date of Patent: April 16, 2002Assignee: Nortel Networks LimitedInventors: Timothy A.

Patent number: 5170275Abstract: A transmitted (TX) signal received from the remote location is mixed in a polarization resolving beam splitter (10) with a local oscillator (LO) signal from a laser (15). The LO and TX signal components emerging from the beam splitter (10) are orthogonally polarized, but their polarization states are brought into alignment by passage through two birefringent elements (19, 20) before falling on two photodetectors (17, 18). Adjustment of a polarization controller (16) ensures that approximately equal LO power falls on each photodetector.Type: GrantFiled: June 14, 1991Date of Patent: December 8, 1992Assignee: Northern Telecom LimitedInventor: Timothy A.

Patent number: 5115480Abstract: A planar coil of single mode fiber has opposed ends twisted into orthogonal planes to form a non-planar coil 20 exhibiting circular birefringence. The amount of birefringence exhibited is modulated by means of an electromechanical transducer 34 which controls the distance separating two diametrically opposed portions of the coil. Two or more such controllers may be formed in tandem with intervening additional coils 50 providing quarter-wave linear birefringence.Type: GrantFiled: March 19, 1991Date of Patent: May 19, 1992Assignee: Northern Telecom Europe LimitedInventor: Timothy A.
