    摘要: In a radial minute gap between a substantially columnar shaft and an inner peripheral face of a substantially cylindrical sleeve, oil is retained and a radial dynamic pressure bearing is formed. A plurality of recessed portions are arranged in a circumferential direction on at least one of an outer peripheral face of the shaft and the inner peripheral face of the sleeve and a first hill portion is provided to an axial end portion of each the recessed portion. Thus, it is possible to achieve a dynamic pressure bearing with which sufficient radial shaft support can be obtained in spite of a short axial length.

    摘要: The present invention discloses a method and system for implementing a three-dimension positioning. The method comprises: receiving, by an optical sensor, infrared rays emitted from an infrared reference light source; and determining a position of the optical sensor with respect to the infrared reference light source based on attributes of the infrared reference light source in images obtained by the optical sensor, so as to implement a three-dimension relative positioning of the optical sensor. The method and system determine the position of the optical sensor with respect to the infrared reference light source by means of the attributes of the infrared reference light source in the images, which are simple in implementation, of a relatively low cost and can provide an excellent positioning function for application contexts of relative positioning (such as immersive video), which greatly improves the experience of a user.

    摘要: The present invention provides a SIP-based network video surveillance system and method, which relates to the application field of network video surveillance. The network video surveillance method comprises the steps of: receiving a request message from a client by a call control server (CCS), the request message comprising an ID of a Premises Unit (PU) and a channel ID; forwarding the request message to a center management server (CMS) by the CCS for access authentication; transmitting the request message to the PU by the CCS after the request message passes the access authentication; responding by the PU an acknowledgement message containing video codec information to the CMS via the CCS; forwarding the acknowledgement message containing the video codec information and an access path to the client by the CMS, then establishing, by the client, a video stream connection with a network element directed by the access path on the basis of the acknowledge message. The present invention uses SIP in conjunction with other protocols to build a complete video surveillance architecture, improving the extensibility of a platform and makes the whole system more stable and reliable.

    摘要: A bearing assembly for use in an electric motor minimizes the generation of a negative pressure. In the bearing assembly, gaps are formed between a shaft provided with a flange portion, a ring member mounted on the shaft, and a sleeve member with a through hole formed therein are continuously filled with lubrication oil. When a rotor rotates, the rotor is supported by a fluid dynamic pressure. In the bearing assembly, herringbone grooves are formed in an upper surface of the flange portion of the shaft fixed to a base plate. When the sleeve member rotates with respect to the shaft, ends of all of the herringbone grooves and the through hole are superposed on each other sequentially. Thus, the lubrication oil can be efficiently supplied to an outer peripheral region in the thrust dynamic pressure bearing mechanism in which the negative pressure is most prone to be generated, and generation of the negative pressure can be efficiently minimized.
