    Abstract: A system and method for producing an image having high dynamic range is described. The system comprises: a light source for providing light along an optical path; a digital micromirror device for directing portions of the light to off-state and on-state light paths, thereby producing an image; and a deformable optical element disposed in the optical path between the light source and the digital micromirror device for steering at least some of the light from the off-state light path to the on-state light path to increase dynamic range of the image produced by the digital micromirror device. The deformable optical element can comprise at least one steerable segment and at least one static element.

  • Patent number: 9026596
    Abstract: Embodiments are disclosed that relate to sharing media streams capturing different perspectives of an event. For example, one embodiment provides, on a computing device, a method including storing an event definition for an event, receiving from each capture device of a plurality of capture devices a request to share a media stream provided by the capture device, receiving a media stream from each capture device of the plurality of capture devices, and associating a subset of media streams from the plurality of capture devices with the event based upon the event definition. The method further includes receiving a request for transmission of a selected media stream associated with the event, and sending the selected media stream associated with the event to the requesting capture device.

  • Patent number: 9024530
    Abstract: An electronic device may be provided that has a display. The display may produce light using a backlight unit or using an array of light-emitting display pixels. An ambient light sensor may be mounted under an active area of the display to measure ambient light that is transmitted through the display. The display may be periodically disabled to prevent the display from producing light that interferes with the ambient light sensor. Display pixels may be coupled to a common cathode switch that can be periodically opened or the backlight in a display with a backlight can be periodically turned off. Control circuitry for periodically disabling the display while enabling the ambient light sensor may be implemented using a display driver integrated circuit mounted to a display.

  • Patent number: 9024899
    Abstract: Example apparatus and methods concern automated testing of a capacitive touch interface (e.g., touch screen). One example apparatus includes probes that extend and retract from the apparatus under programmatic control. The probes produce a capacitive touch response on a capacitive touch interface. The example apparatus includes logics configured to control touch testing of the interface using the probes. A first logic may provide a closed loop vision system for controlling the position of the interface relative to the apparatus. A second logic may calibrate a co-ordinate system associated with the apparatus and a co-ordinate system associated with the interface so that the apparatus may function in the pixel space of the interface being tested. A third logic may control the probes to test the interface by producing a series of touches, multi-touches, or gestures on the interface.

  • Publication number: 20150116345
    Abstract: A substantially self-contained digital instrumentation module (30) for fixed and rotary wing aircraft provides flight and other situational information, such as attitude, altitude, airspeed, and slip information, during normal aircraft operation or during emergencies, such as a failure of the aircraft's primary instrumentation. The module (30) can be mounted in any of various possible orientations. It includes redundant memories (38,40,50,52) to preserve back-up copies of software and settings during upgrades and changes. It partitions certified software from non-certified software. It can receive software upgrades and settings changes via a common portable memory device. It can automatically calculate and synchronize barometric pressure with the aircraft's primary instrumentation. It also allows for creating a customizable dimming curve (220,222), and for creating customizable range markings (114).

  • Patent number: 9019252
    Abstract: A display device includes a display unit, a display control unit, and a control unit. The display unit includes a first and second glass plates, each formed with an electrode connected to a power supply and configured to transmit a light, and a light dispersing element sealed between the first and the second glass plates. The light dispersing element transmits the light when a voltage from the power supply is turned on, and disperses the light when the voltage is turned off. The display control unit controls a timing of turning the voltage on or off, or switching the voltage between positive and negative when the voltage is turned on. The control unit instructs the display control unit to set a display frame rate to a predetermined value during a standby mode, and set it higher than the predetermined value during an information display mode.

  • Patent number: 9019251
    Abstract: Ambient light is sensed for use in determining luminous flux. According to an example embodiment, ambient light is sensed using two light sensor arrangements that respectively respond differently to light of different relative wavelengths. The output of the sensors is nonlinearly combined to generate data indicative of the luminous flux. This luminous flux data is used to generate a control output for controlling an electronic display.

  • Patent number: 9019253
    Abstract: Systems and methods for adjusting a color space of a display. In one embodiment, the method for adjusting the color space of the display may include receiving image data to be rendered on the display and receiving an indication of an amount of ambient light impinging on the display. The method may then include rendering the image data in a first color space when the amount of ambient light is less than a threshold. Alternatively, the method may include rendering the image data in an expanded color space when the amount of ambient light is not less than the threshold. As such, the expanded color space may compensate for one or more color shifts in the image data caused by the ambient light.

  • Publication number: 20150109270
    Abstract: When a 2D display is performed, a controller causes a first selection signal to be in an active state during a given period, and causes a second selection signal to be in the active state during another given period after causing the first selection signal to be in a non-active state. When a 3D display is performed, the controller causes the first selection signal to be in the active state at a given timing point, cause the second selection signal to be in the active state during a period when the first selection signal is in the active state, and thereby cause an overlapping period to arise during a period which is part of a selection period for selecting signal lines corresponding to the first selection signal, and which is part of another selection period for selecting signal lines corresponding to the second selection signal.

  • Patent number: 9013401
    Abstract: Measuring audience size for a digital sign comprises generating a plurality of paths, one for each face detected in a first sequence of video frames captured by a camera proximate the digital sign, and generating a zone in the sequence of video frames through which passes a threshold number of the paths. Motion and direction of motion within the zone is then measured in a second sequence of video frames to calculate the audience size that passes through the zone in the second sequence of video frames.
