IPC: H04N1/41
Filed: 1991-08-28
Abstract: Adaptive Buffer/Quantizer Control for Transform Video Coders Abstract A buffer/quantizer controller in a video coder utilizes the average quantization step size employed for the previous frame, the average number of bits produced per pel by the video coder for the image contained in the previous frame and the current frame buffer fullness level to obtain an indication of image complexity. A target current frame quantization step size be employed by the video coder in encoding a current frame is based on the indication of image complexity. Optionally, the target frame quantization step size is adjusted by amapping procedure, at predetermined intervals within each frame period, to account for the current buffer fullness. The map employed by the mapping procedure is adjusted in accordance with the target frame quantization step size [FIG. 3].

Patent CA-2054496-A1 (CA)
Inventor: SVENSSON THOMAS
IPC: A61B17/56
Filed: 1991-12-31
Abstract: The invention relates to a spacing member arranged between a securing element (fixture) implanted in the facial bone (the cranium) and an extraoral prosthesis, in particular a facial prosthesis. The spacing member comprises a base portion (1) intended to cooperate with the upper portion of the securing element, and an extension part (8, 8') which forms an attachment point for the prosthesis. The extension part (8, 8') is designed in such a way that it permits attachment of~the prosthesis in a direction (attachment direction] which forms essentially a right angle to the longitudinal direction of the extension part. The spacing member combines the two conflicting requirements which exist particularly in the case of an orbital prosthesis, namely secure anchoring in the bone (radial,attachment of the securing elements) and a more favourable attachment direction (axial) for the prosthetic work.

Abstract: A well tool includes a whipstock in conjunction with an inflatable packer for use in the open hole.  A pivotal joint between the whipstock and packer allows the whipstock to pivot relative to the packer and springs bias the whipstock into an angled relation relative to the packer.  A setting tool connects the whipstock and packer in a rigid straight line position while the tool is being run into the hole. Drilling fluid can be circulated through the tool.  When the packer is set and the setting tool is removed, the whipstock pivots relative to the packer against the side of the open hole.  This allows the hole to be sidetracked from the low side of the hole.
