  • Patent number: 10984695
    Abstract: A display driving device is disclosed. The display driving device includes: a data signal end for providing a data signal, a source line, and a switching circuit. The source line can transmit the data signal to a first pixel circuit and a second pixel circuit. Along a direction of the source line, a distance between the second pixel circuit and the data signal end is larger than a distance between the first pixel circuit and the data signal end. The switching circuit is between the data signal end and the source line, and can be turned on in response to a first control signal, and can be turned on in response to a second control signal. A turned-on time period of the switching circuit in response to the second control signal is longer than a turned-on time period of the switching circuit in response to the first control signal.

  • Publication number: 20200213486
    Abstract: A system for capturing and processing an image in a camera system for a vehicle includes a camera module with a lens and a sensor, an image signal processor, a control unit, and an infrared elimination mechanism. The system may include at least one infrared illuminator. In normal light conditions, the infrared portion of the light is not used. The system may include an IR-cut filter disposed within the camera module that is moveable between a filtered position where infrared light is blocked before reaching an RGB sensor in normal light conditions and an unfiltered position where all of the light reaches the RGB sensor in low light conditions. The system may include an RGB-IR sensor without a filter, and the infrared portion captured at the sensor is ignored in normal light conditions and, in low light conditions, the infrared portion is used.

  • Patent number: 9355111
    Abstract: Computer-readable media, systems, and methods for hierarchical index based compression are described. In embodiments, a hierarchical data log or key-value pair based data log, such as a JSON log, is received and a tree-structured index (index tree) is recursively constructed. In one embodiment, the log comprises search-engine user interaction information. Structural information of the log is preserved by the index tree structure; for example, each node of the log has a corresponding index-tree node. Frequently repeating keys, values, and correlated key-value pairs may be stored in the index-tree node, which may be indexed using multiple levels of detail including a raw-string level for raw string representations of the node, a first level for indexing keys and common values, and a second level for indexing correlated key-value pairs. The index tree may be used to compress rows of the data log and also used to decompress and restore the log.

  • Publication number: 20150326880
    Abstract: The techniques of this disclosure generally relate to using motion information for a corresponding block from a texture view component that corresponds with a block in a depth view component in coding the block in the depth view component. In some examples, for coding purposes, the techniques may use motion information when the spatial resolution of the texture view component is different than the spatial resolution of the depth view component. Among the various IMVP techniques described in this disclosure, this disclosure describes IVMP techniques for use in coding scenarios where a partition of a depth view macroblock (MB) corresponds to a texture view MB that is either intra coded or partitioned into four partitions.

  • Patent number: 6327030
    Abstract: The subject invention relates to a strain-sensitive coating, a strain measurement system, and a method to determine strains on substrate materials. In a preferred embodiment of the subject invention, the system includes a luminescent strain-sensitive coating and a strain field mapping system which can be used to create a strain map of the mechanical strain on a substrate material. The luminescent strain-sensitive coating of the subject invention is preferably a polymer-based coating, and can incorporate one or more luminescent compounds. The subject coating can be applied to produce a thin film on a substrate material, such as aluminum, steel, polymer, or composite. One or more characteristics of the luminescence emanating from the coating can then vary in relation to the strain on the substrate material.
