Title: Modifying a coded bitstream
Inventor: ZOU DEKUN
IPC: G06T1/00
Filed: 2008-06-13
Abstract: Various implementations are provided for, for example, determining watermarking data, performing the watermarking, and processing watermarked data. At least one implementation watermarks AVC bitstream that uses CAVLC entropy coding. The watermarking data may be determined in a pre-processing stage and stored for later use in watermark a bitstream. One method accesses (810) variable-length encoded data including an encoding of information identifying an actual reference used to predictively encode an image. The encoding of the information has a particular value. The method determines (830) an alternative value that is different from the particular value, such that the alternative value is an encoding of alternative information that identifies a different reference from the actual reference. The alternative value is for use in watermarking the variable-length encoded data.

Patent CA-2693206-A1 (CA)
Inventor: SIEGAL TZONY
IPC: A61B17/70
Filed: 2008-08-11
Abstract: An implant for maintaining a given minimum inter-spinous-process spacing includes an implant body with a number of segments hingedly interconnected so as to assume a straightened state for delivery along a conduit and a curved deployed state. An elongated tightening element is anchored at the distal segment of the implant body and passes along a channel extending along the implant body. Tension applied to the tightening element biases the implant body from the straightened state to the curved deployed state. Preferably, when the tightening element is deflected to reach the curved deployed state, a locking arrangement locks the tightening element relative to the implant body, thereby retaining the implant in the curved deployed state. A distal portion of the implant body is preferably formed with a set of lateral projections to inhibit withdrawal of the distal portion between adjacent spinous processes after deployment.

Title: Method and apparatus for using service capability information for user plane location
Inventor: FARMER DOMINIC GERARD
IPC: H04W4/20
Filed: 2009-01-09
Abstract: Techniques for supporting location services in a user plane location architecture such as Secure User Plane Location (SUPL) are de-scribed.    In an aspect, a terminal informs a location server of service capa-bilities of the terminal. The location server uses the service capabilities to request only location services supported by the terminal and to avoid re-questing unsupported location services. The terminal generates a message containing its service capabilities and sends the message via a user plane, e.g., SUPL. The location server receives the message, obtains the service capabilities of the terminal, and stores these service capabilities for future network-initiated location sessions with the terminal. The location server determines whether a location service is supported by the terminal based on the service capabilities of the terminal. The location server communicates with the terminal via the user plane for the location service if supported by the terminal.

Abstract: Apparatus is disclosed and comprises a cap, a body and a connector. The cap has an inner surface defining a hollow. The body includes a vial having a rim and an opening bounded by the rim. The connector couples the cap and body in a manner which permits cap movement between a fully-seated position on the vial, to form a sealed specimen container; and a position apart from the opening, to permit ingress to the vial. The connector can be adapted such that, in use, when the cap is disposed at the position apart from the opening, and in the absence of external forces, the connector holds the cap at the position apart from the opening. Snap-fit intermediate positions of the cap can be provided between the position apart from the opening and the fully-seated position and the cap can be adapted to reduce evaporative losses when intermediately positioned.
