  • Patent number: 10484629
    Abstract: A method and device for improving the accuracy of depth information derived from a structured-light image for a regular image are disclosed. In one example, an additional structured-light image is captured before a first structured-light image or after a regular image. The depth information for the regular image can be derived from the first structured-light image and corrected by incorporating depth information from the additional structured-light image. A model for depth information can be used to predict or interpolate depth information for the regular image. In another example, two regular sub-images may be captured with a structured-light image in between. If substantial frame differences or substantial global motion vector/block motion vectors are detected, the two regular sub-images will not be combined in order to avoid possible motion smear. Instead, one of the two sub-images will be selected and scaled as the output regular image.

  • Patent number: 10438753
    Abstract: This invention described the preparation of a series of compounds that can be used as co-solvents, solutes or additives in non-aqueous electrolytes and their test results in various electrochemical devices. The inclusion of these novel compounds in electrolyte systems can enable rechargeable chemistries at high voltages that are otherwise impossible with state-of-the-art electrolyte technologies. These compounds are so chosen because of their beneficial effect on the interphasial chemistries formed at high potentials, such as 5.0 V class cathodes for new Li ion chemistries. The potential application of these compounds goes beyond Li ion battery technology and covers any electrochemical device that employs non-aqueous electrolytes for the benefit of high energy density resultant from high operating voltages.

  • Patent number: 10402992
    Abstract: A method and apparatus for capturing images of a scene using a capsule device including a camera are disclosed. An image sequence is captured using the camera when the capsule device travels through a human gastrointestinal tract. Also, structured-light images are captured using the camera by projecting structured light to one or more objects in a field of view of the camera when the capsule device travels through the human gastrointestinal tract. The structured-light images are interleaved with regular images in the image sequence. The distance information with respect to the capsule camera associated with objects of the selected image is derived. Both the image sequence and the distance information are outputted. A method of determining the size of an object of interest utilizing the distance information is also disclosed. In another method, the distance information is used to scale object or adjust intensities.

  • Publication number: 20190250944
    Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for an availability oriented durability technique for distributed server systems. A server that is an entry point for a message processing stream receives a message from a client device, and in response, generating a unique identifier for the message, and adds an entry in a transaction log that including the message and the unique identifier for the message. The server appends the unique identifier to the message, and transmits the message to a second server positioned downstream from the server in the message processing stream. If the server determines that the message has not been processed through the message processing stream, the server accesses the message from the transaction log, appends the unique identifier to the first message, and re-transmitting the message to the second server positioned downstream from the server in the message processing stream.

  • Patent number: 10356941
    Abstract: An air-cooling heat dissipation device includes a base, a swirling-airflow heatsink, an air pump and a passage connector. The base is located beside an electronic component while the air pump is fixed on the base. The swirling-airflow heatsink is attached on the electronic component and includes a swirling passage defined by a conductive line and a thermal conduction plate collaboratively. An airflow-guiding chamber is defined by the air pump and the base collaboratively, and the airflow-guiding chamber is in communication with the swirling passage by the passage connector. When the air pump is enabled, an ambient air is introduced into the airflow-guiding chamber of the base and transferred to the swirling passage of the swirling-airflow heatsink through a discharge opening of the base and the passage connector. Consequently, a fast swirling air flow is produced to cool the electronic component.
