  • Publication number: 20240394944
    Abstract: A data generation system and method for generating sensor-realistic sensor data. The data generation computer system includes: at least one processor, and memory storing computer instructions. The data generation system is, upon execution of the computer instructions by the at least one processor. The method includes: obtaining background sensor data from sensor data of a sensor; augmenting the sensor background data with one or more objects to generate an augmented background sensor output, wherein the augmenting the background sensor data includes determining a two-dimensional (2D) representation of each of the one or more objects based on a pose of the sensor; and generating sensor-realistic augmented sensor data based on the augmented background sensor output through use of a domain transfer network that takes, as input, the augmented background sensor output and generates, as output, the sensor-realistic augmented sensor data.

  • Patent number: 10973391
    Abstract: A system for virtual reality/mixed reality viewing of a surgical procedure includes an endoscope having an elongated flexible or rigid main body with a proximal end and a distal end. A spherical element is coupled to the distal end. A plurality of wide field-of-view cameras or optical collections lenses are aligned about the spherical element to provide 360 degree omnidirectional stereoscopic visualization. A fiber optic illumination strip is positioned around the periphery of the spherical element adjacent each camera. A central processing unit is in communication with the plurality of cameras/lenses configured to receive real-time video from each of the plurality of cameras or lenses. A partial field-of-view virtual reality headset or a mixed reality headset is electronically coupled to the central processing unit. The headset displays real-time video from a select portion of the plurality of cameras or lenses, which provides 360 degree omnidirectional visualization based upon a position of the headset.

    Abstract: The present invention relates to a messaging technique, and more specifically, relates to a method and system for messaging using information of predetermined message recipients. According to one aspect of the present invention, there is provided a method for messaging, comprising: obtaining message recipients designated by a to-be-sent message; obtaining predetermined message recipients corresponding to the to-be-sent message; and in response to inconsistency between the designated message recipients and the predetermined message recipients, unifying the designated message recipients and the predetermined message recipients. According to the method and system for messaging provided by the present invention, message recipients may be efficiently controlled and uniformed so as to avoid missing of recipients or to promptly update message recipient information. Further, the messaged content can be efficiently controlled and unified.

  • Patent number: 8462786
    Abstract: A method is provided for constructing a packet classifier for a computer network system. The method includes: receiving a set of rules for packet classification, where a rule sets forth values for fields in a data packet and a decision for data packets having matching field values; representing the set of rules as a directed graph; partitioning the graph into at least two partitions; generating at least one lookup table for each partition of the graph; and instantiating the lookup tables from one partition on a first content-addressable memory and the lookup tables from the other partition on a second content-addressable memory device.

  • Patent number: 8445383
    Abstract: A heterojunction between thin films of NCD and 4H—SiC was developed. Undoped and B-doped NCDs were deposited on both n? and p? SiC epilayers. I-V measurements on p+ NCD/n? SiC indicated Schottky rectifying behavior with a turn-on voltage of around 0.2 V. The current increased over eight orders of magnitude with an ideality factor of 1.17 at 30° C. Ideal energy-band diagrams suggested a possible conduction mechanism for electron transport from the SiC conduction band to either the valence band or acceptor level of the NCD film.
