  • Publication number: 20190079302
    Abstract: A wearable device for augmented media content experiences can be formed with a mountable physical structure that has removably mountable positions and component devices that are removably mounted through the removably mountable positions. The component devices can be specifically selected based on a specific type of content consumption environment in which the wearable device is to operate. The mountable physical structure may be subject to a device washing process to which the component devices are not subject to, after the wearable device including the mountable physical structure and the component devices is used by a viewer in a content consumption session in the specific type of content consumption environment, so long as the component devices are subsequently removed from the mountable physical structure.

  • Publication number: 20180295352
    Abstract: A spatial direction of a wearable device that represents an actual viewing direction of the wearable device is determined. The spatial direction of the wearable device is used to select, from a multi-view image comprising single-view images, a set of single-view images. A display image is caused to be rendered on a device display of the wearable device. The display image represents a single-view image as viewed from the actual viewing direction of the wearable device. The display image is constructed based on the spatial direction of the wearable device and the set of single-view images.

  • Publication number: 20180295351
    Abstract: A wearable device comprises a left view optical stack for a viewer to view left view cinema display images rendered on a cinema display and a right view optical stack for the viewer to view right view cinema display images rendered on the cinema display. The left view cinema display images and the right view cinema display images form stereoscopic cinema images. The wearable device further comprises a left view imager that renders left view device display images, to the viewer, on a device display, and a right view imager that renders right view device display images, to the viewer, on the device display. The left view device display images and the right view device display images form stereoscopic device images complementary to the stereoscopic cinema images.

  • Publication number: 20180293752
    Abstract: At a first time point, a first light capturing device at a first spatial location in a three-dimensional (3D) space captures first light rays from light sources located at designated spatial locations on a viewer device in the 3D space. At the first time point, a second light capturing device at a second spatial location in the 3D space captures second light rays from the light sources located at the designated spatial locations on the viewer device in the 3D space. Based on the first light rays captured by the first light capturing device and the second light rays captured by the second light capturing device, at least one of a spatial position and a spatial direction, at the first time point, of the viewer device is determined.

  • Patent number: 9035975
    Abstract: Techniques for using variable flower assemblies to control light leakage between designated portions of light-emitting elements are provided. In some embodiments, a variable flower assembly comprises a plurality of light-transmissive segments each may be electronically set to a different light-transparency level. The variable flower assembly substantially forms a tube around a light-emitting element mounted on a first plane. A first edge of each of the light-transmissive segments collectively surrounds the light-emitting element on a second plane substantially parallel to the first plane. A second opposing edge of each of the light-transmissive segments collectively forms an opening of the tube. In some embodiments, a reflective assembly which reflectance level is electronically controllable may surround the variable flower assembly.

  • Publication number: 20140307011
    Abstract: Techniques are provided to provide various pulse width modulation (PWM) schemes to embodiments of dual modulator display systems that may comprise a backlight of individually addressable and controllable light emitters. The backlight provides illumination to a light modulator for further conditioning of the light to be presented to a viewer. The backlight may be striped and each stripe is assigned a PWM scheme that effectively increases the bit depth of the controller for each stripe. The display system may allow a better matching of PWM periods to LCD frame rates to reduce visual artifacts. In another embodiment, the display system may detect a small bright feature to be rendered in the image data and, with a pre-assignment of light emitters to different partitions, the backlight controller may drive a subset of the light emitters according to the partitions.

  • Patent number: 8836736
    Abstract: Techniques for using variable flower assemblies to control light leakage between designated portions of light-emitting elements are provided. In some embodiments, a variable flower assembly (100) comprises a plurality of light-transmissive segments (102-1, 102-2, . . . , 102-6) each may be electronically set to a different light-transparency level. The variable flower assembly substantially forms a tube around a light-emitting element (104) mounted on a first plane. A first edge of each of the light-transmissive segments collectively surrounds the light-emitting element on a second plane substantially parallel to the first plane. A second opposing edge of each of the light-transmissive segments collectively forms an opening of the tube. In some embodiments, a reflective assembly (120) which reflectance level is electronically controllable may surround the variable flower assembly.

  • Patent number: 7339943
    Abstract: An apparatus is described that includes a plurality of queuing paths. Each of the queuing paths further comprises an input queue, an intermediate queue and an output queue. The input queue has an output coupled to an input of the intermediate queue and the input of the output queue. The intermediate queue has an output coupled to the input of the output queue. The intermediate queue receives data units from the input queue if a state of the input queue has reached a threshold. The output queue receives data units from the intermediate queue if the intermediate queue has data units. The output queue receives data units from the input queue if the intermediate queue does not have data units.

  • Patent number: 7206857
    Abstract: A method is described that involves recognizing that an input queue state has reached a buffer's worth of information. The method also involves generating a first request to read a buffer's worth of information from an input RAM that implements the input queue. The method further involves recognizing that an output queue has room to receive information and that an intermediate queue that provides information to the output queue does not have information waiting to be forwarded to the output queue. The method also involves generating a second request to read information from the input RAM so that at least a portion of the room can be filled. The method also involves granting one of the first and second requests.

  • Patent number: 6983403
    Abstract: Error codes output from a serializer/deserializer in a node of a communications network are detected by error decode logic that assumes that each new error occurrence reflects a one bit error in the word giving rise to the error code. Each error occurrence is then counted. When the error count reaches a predetermined limit (e.g., 250 errors), the total bit count required to accumulate the 250 errors is then determined. The total bits can be determined based on a clock count (time). The BER is then calculated based upon the fixed error limit and the total bit count. This BER is then reported and used to determine the health of the network.
