  • Publication number: 20170227298
    Abstract: A three-dimensional heat transfer device includes a vapor chamber and at least one heat pipe. The vapor chamber has a first plate and a second plate opposite to each other, and a first capillary structure is disposed on an inner surface of the first plate. A second capillary structure is disposed in the heat pipe, the second capillary structure has a contact portion extending out of the heat pipe and exposed therefrom. The heat pipe is vertically inserted through the second plate. The contact portion extends into the vapor chamber and is connected to the first capillary structure, so that the first and second capillary structures communicate with each other. Therefore, an overall three-dimensional heat transfer effect can be achieved, and a desired optimized heat dissipation effect is obtained when the vapor chamber collaborates with the heat pipe.

  • Patent number: 9542624
    Abstract: The present invention discloses recognizing methods of flaky or blocky prohibited articles, explosives or drugs. Specifically, the method for recognizing flaky prohibited articles, explosives or drugs comprises steps of: (1) reading in tomogram data of an object to be inspected for one tomogram; (2) pre-processing the tomogram data; (3) splitting the pre-processed tomogram data into a plurality of regions that have similar physical properties; (4) analyzing whether each of the split regions is a flaky region; (5) determining whether the flaky region recognized in the current tomogram can be merged with the flaky region detected from the previous tomogram, so as to form a flaky target; (6) determining whether each detected flaky target is complete or finished; (7) repeating steps (1)-(6) and processing each tomogram data layer by layer, until all of the tomogram data have been processed.

  • Publication number: 20160359713
    Abstract: The disclosure is related to a framework that enables server-side controlling of data sampling at client devices. An application executing on a client device samples data related to various aspects of the application, generates a log file containing the sample data and transmits the log file to the server. The application samples the data based on specified criteria, e.g., specified events, specified actions of a user of the client device, at a specified sampling rate. The framework enables controlling the sampling of such data from the server. The framework can be used to configure various parameters of the sampling, including a number of users to be sampled, a set of events to be sampled, a sampling rate for the events, etc. After the configuration is determined, the server transmits a configuration file to the client device, which performs the sampling based on the configuration in the configuration file.

  • Publication number: 20160330868
    Abstract: A cooling module used in conjunction with a heating element includes a vapor chamber and a plurality of cooling fins. The vapor chamber is in contact with one side of the heating element. The vapor chamber is disposed with a direct conduction area and a vacuum block disposed on two sides of the direct conduction area respectively. Each vacuum block forms a chamber. The cooling fins protrude from and are vertically disposed on the direct conduction area and each vacuum block, respectively. Thereby, the effects of fast vertical heat transfer to the fin and fast horizontal heat transfer to the distal cooling fins are achieved.
