Abstract: A 3D vapor chamber includes a vapor chamber and at least one pipe body. The vapor chamber has an upper plate and a lower plate mated with each other. The upper plate is formed with at least one perforation. An open end of the pipe body is outward expanded to form a lip section in connection with the upper plate. A closed end of the pipe body passes through the perforation of the upper plate. The closed end and the open end together define a tubular chamber in communication with the open end and the vapor chamber. Multiple channels formed on an inner side of the tubular chamber and an inner side of the lip section are in contact and connect with a capillary structure of the inner side of the upper plate so as to increase back flowing speed of a working fluid and enhance heat dissipation performance.

Abstract: The present invention discloses a functional powder delivery device for precise locating and quantifying when delivering the functional powder to a site in need in a patient. Meanwhile, the device avoids negative pressure effect in the output catheter when airflow is switched, and thus prevents pollution or jam in the output catheter due to splash or back flow of body fluid. The device ensures tube clearance of the output catheter by maintaining continuous airflow, and a special design of airflow switch allows switching to airflow of large volume to carry the powder when required. Through continuous positive airflow in the tube system, the functional powder can be delivered to the site in need by a continuous powder flow, which overcomes drawbacks of the delivery devices in prior arts. In addition, the design of foot pedal can help endoscopist for a solo operation. The serial connecting parts can adapt for various size of bottles of various types of functional powder.

The 4D printed gripper with flexible finger joints includes: a palm unit and five finger units connected to the palm unit, where each finger unit includes two flexible finger joints and two phalanges; each flexible finger joint is divided into one upper layer and one lower layer of liquid crystal elastomer (LCE), and each LCE is used to implement a bidirectional bending movement of the finger unit. The present disclosure can precisely control the gripper with flexible finger joints.

Abstract: A vapor chamber reinforcement structure includes an upper cover and a lower plate. The upper cover is recessed to form at least one channel An opposite side of the channel is protruded to form at least one raised body. The lower plate is used to contact with a heat source and has a first capillary structure. The lower plate is correspondingly mated with the upper cover to form an airtight chamber for filling a working fluid. By means of the channel and the raised body disposed on the opposite side of the channel, the channel provides larger heat contact area for the heat conduction component (heat pipe) and more secure connection ability. Also, the raised body on the opposite side of the channel enhances the structural strength of the entire vapor chamber and enlarges the condensation contact area of the vapor chamber.

Abstract: The present invention provides a compound wick structure of a vapor chamber, which comprises a first plate and a second plate. The first plate has a first side and a second side. The second plate has a third side and a fourth side. The first plate and the second plate are assembled together to form a sealed chamber. The third side of the second plate is provided with a mesh or a fiber body; the third side has at least one heated zone having a first sintered-powder structure. The first sintered-powder structure is selected to be connected to or in contact with the mesh or the fiber body. A working liquid is disposed in the sealed chamber. By means of the arrangement of the compound wick structure, the vertical and horizontal flow-back efficiencies of the working liquid are enhanced and the efficiency of liquid-vapor cycle is increased.

Abstract: Techniques for determining exciting moments in a game video are described herein. The disclosed techniques comprise capturing a video frame in a target game video; obtaining an icon associated with a game character in the video frame; determining a corresponding health point of the game character in the video frame based on the icon; determining a health point change of the game character by comparing a plurality of health points of the game character in the plurality of video frames; and determining at least one exciting moment in the target game video based on the health point change.

Abstract: A preliminary positioning method for a TPMS uses a receiver to receive a tire pressure signal, then obtains the ID code contained in the obtained tire pressure signal, then compares the ID code with the corresponding ID codes stored in the database, and defines the ID code as a known ID code, when the ID code is found to match with one of the corresponding ID codes prestored in the database. Repeating the above steps until the ID codes of all received tire pressure signals all have been compared. If the number of the known ID codes is equal to the number of the sensors, the known ID codes are designated as specific tires according to an indication of the respective tire pressure signals, so that the positioning function can be achieved in a short period of time.

Abstract: An electronic device includes a bottom wall, a board perpendicularly connected to the bottom wall, a fan, and a frame receiving the fan. The board defines a vent and two notches above the vent. Each notch extends through a top side of the board. A power connector is mounted to the bottom wall, adjacent to the vent. A switch is mounted to a side of the frame and is electrically connected to the fan. Two fixing members are mounted to the frame to engage in the notches in a vertical direction, therefore, the switch is electrically connected to the power connector.

Abstract: A server includes an enclosure, a motherboard, and first and second switches. The enclosure includes a base and a cover. The first switch is used to manually turn on or off the motherboard. The second switch is capable of turning off the motherboard and is mounted on a sidewall of the base. A stopping piece extends down from one side of the cover to abut against the second switch. The second switch is connected to a power-on pin of the motherboard. When the cover is not covering the base, the stopping piece fails to abut against the second switch. And the second switch is turned off. The power-on pin receives a power-off signal to power off the server.
