Abstract: The invention relates to compressed data transmission in wireless data communication. Disclosed are methods and apparatuses for transporting residue of vehicle position data via a wireless network. A disclosed method for transporting residue of vehicle position data via a wireless network, includes the steps of: receiving data for updating residue encoding schema from a monitoring server; constructing a residue encoding schema based on the data, thereby producing a constructed residue encoding schema; and storing the constructed residue encoding schema such that the constructed residue encoding schema will become the current residue encoding schema; where: the constructed residue encoding schema is constructed such that each residue of the constructed residue encoding schema corresponds to a code; and the constructed residue encoding schema is constructed such that a residue having a relatively high probability of occurrence corresponds to a code of relatively short length.

Abstract: The present invention provides a radio frequency identification tag gripper device, the technical scheme including: a first gripper portion; a second gripper portion, which generates a gripping force together with the first gripper portion; a radio frequency identification tag, a circuit portion of which is divided into at least a first section and a second section, an upper surface of the first section and a lower surface of the second section being coated with strong glue, wherein the upper surface of the first section is used to bond with a grip surface of the first gripper portion when gripped tightly, and the lower surface of the second section is used to produce a coupling force with a surface of the gripped object when gripped tightly. Utilizing the technical solution of the present invention, it is possible to further improve the security of monitoring of the radio frequency identification tag.

Abstract: A switch monitoring method and a switch monitoring system, a railway line management method and a railway line management system are provided. Electric signal of a switch motor during pulling of the switch can effectively reflect status of the switch, when the switch is in a stable state, electric signal of its motor is very steady during pulling of a switch of the switch; however, when the switch is in an unstable state, there will be different degrees of fluctuation in electric signal of its motor during pulling of the switch. Thus, the invention may be used to identify state of a switch by monitoring electric signal of a switch motor (201,203,205), and further take different measures based on different states of the switch (401,403,405). With these measures, accidents due to switch failure may be effectively reduced, and train delay time may also be reduced through proper line management.

Abstract: The present invention relates to multi-user analytical system and corresponding device and method. The device includes an interception module configured to intercept a user's request for a first core object, wherein the first core object belongs to core object; a transformation module configured to create, in response to the request being a creation request, the first core object specific to the user; a mapping module configured to interpret, in response to the request being a non-creation request, the request as a request for the first core object specific to the user. The present invention also includes an isolation method for the multi-user analytical system. The technical solutions provided in the present invention can effectively enable multiple users to share physical resources in the analytical system, and the users are isolated from each other in a substantially transparent way.

Abstract: A method of querying spatial events in a vehicle network includes receiving, by a processing device, a query condition of a user; in response to reception of the query condition of the user, determining context information of a position where the user locates; and according to the query condition of the user and the context information of the position where the user locates, querying an index table recording correspondence between terminal nodes of roads in a road map and spatial events to obtain spatial events meeting the query condition of the user.

Abstract: The present invention pertains to a multi-position cervical pillow and an adjustable pillow set thereof to support a user's head and neck. In a preferred embodiment, the multi-position cervical pillow comprises a rectangular memory foam pad, the transversal cross section of which is bone-shaped with two lobes protruded towards two opposite lateral ends and a shallow trough in between forming a concave head support portion on each of the two support surfaces; said two lobes are different in size and asymmetrical in shape. By inverting and reversing the pillow pad it provides four unique positions. An adjustable pillow set comprises a main multi-position cervical pillow and an unattached ancillary pillow, the upper surface of the latter has a transversally convex, asymmetrical curvature for the main pillow to stack and slide on top of it, forming four stacking configurations, with each providing two unique positions.

Abstract: The present invention pertains to an automotive recliner seat support device to provide a dynamic support for a driver's foot-leg-hip axis at its lower pelvic end to ease the driver's muscle stress from lower limbs to upper back when the driver is using his/her lower limbs to push the clutch and/or brake pedals in performing normal and emergency driving operations of a vehicle. Two preferred embodiments of the invention are disclosed. The first one is an attachable device intended to retrofit to the existing vehicle seats; whereas the second one is integrated into the seat structure, and is intended to be built into future vehicles.
