Patent CA-2692407-A1 (CA)
Inventor: BAHRE WOLF-FRIEDRICH
IPC: A61B17/12
Filed: 2007-07-03
Abstract: The invention relates to a medical implant capable of being softened by developing internal heat. In a preferred embodiment, the medical implant comprises at least in part, a polymer which is compatible with the body and which is in itself electrically conductive and has a specific electrical resistivity .rho., with the property that it is capable of warming up and softening upon a flow of current through the polymer. The hazards in employing the medical implant according to the invention are reduced because the actual evolution of heat (to soften the polymer) is concentrated inside the implant. In addition, the risk of damaging the tissue through excessive heat is reduced, especially in comparison to the state of the art, which uses an en external heat source.

Abstract: A terminal random access method for cellular radio communications system and method for generating group identifier are provided. The terminal random access method for cellular radio communications system includes steps of: transmitting random access preamble message by a terminal to a base station on a random access time slot within a radio frame; combining location information of the random access time slot within the radio frame and in frequency domain to generate group identifier and sending to the terminal a random access response message after adding the group identifier and individual identifier that corresponds to the random access preamble message to the random access response message by the base station; judging whether the random access response message that corresponds to the sent random access preamble message is received, by judging whether the group identifier and the individual identifier within the received random access response message are all desired value. This invention provides fast and accurately accessing to the cellular radio communications system for the terminal and allows doing simple and easy operation to set group identifier by the same way whether configuration of the random access time slot changes or not.

Abstract: A wind or water turbine mounted atop a support tower or tethered underwater drives a hydro-pumping system. The turbine converts wind or water energy into a driving torque applied to the hydro-pump.  The hydro-pump forces water through a pipe transmission system to an onshore facility. On shore, the resultant pressurized fluid-flow propels a hydroelectric generating system to produce electricity or may first be used in a Reverse Osmosis desalinization process and the byproduct in part used to propel a hydroelectric generating system to produce electricity. The cold-water discharge from the hydroelectric generating system and/or from the desalinization process is used for onshore district or power plant cooling purposes.

Title: Moving image playback apparatus
Inventor: DACHIKU KENSHI
IPC: H04N19/44
Filed: 2008-11-10
Abstract: A moving image playback apparatus capable of starting within a short time to play back reverse direction moving images is provided. The apparatus includes two decoders and one output buffer. In standby, using I-picture in a specified GOP as a reference, a controller causes a storage device to sequentially read first coded image data of the pictures in a first GOP  preceding a specified GOP and the pictures up to I-picture in the specified GOP, and causes a first decoder to decode the first coded image data. Moreover, during the decoding of the first decoder, the controller causes the storage device to sequentially read second coded image data of the pictures in the specified GOP and the pictures up to I-picture in a second GOP following the specified GOP, and causes a second decoder to decode the second coded image data. Thereafter, the controller causes the outputs from the first and second decoders to be written to the output buffer. Thereby, the decoded image data are outputted from the output buffer immediately upon start of reverse playback, and moving images are played back.

Patent CA-2710296-A1 (CA)
Inventor: RESCH KEVIN
IPC: G01N21/41
Filed: 2008-12-19
Abstract: The device is based on a cross-correlator which measures the signal between a pair of oppositely chirped laser pulses. Two laser pulses, one with a positive chirp and one with a negative chirp, are mixed on a beamsplitter. The two resulting beams pass through a reference or a sample arm and are subsequently mixed on a non-lmear crystal. The signal from the interferometer is the sum frequency generation produced in that crystal. The reference arm contains a moveable delay which is used to change the relative timing of the two beams in the interferometer. The sum frequency generation in the narrow band of frequencies is the signal from the device and is measured as a function of the delay. Alternatively, a pure dispersive phase shift could be used in place of the two laser pulses.

Abstract: Methods and apparatus for tracking objects in conduits, especially for tracking the movement of a pig in a pipeline, are disclosed. Distributed acoustic sensing is used to obtain signal returns from a plurality of discrete longitudinal sensing portions of a fibre optic cable which is laid along the length of the conduit. The method involves detecting an acoustic signature corresponding to the object moving in the conduit. The acoustic signature may comprise a series of pressure pulses caused by the object traversing joints etc. in the conduit. Preferably the method involves detecting pressure waves caused by the object as it moves through the conduit. Detecting the characteristic pressure wave signal provides discrimination of the object from other acoustic disturbances. In pipeline applications a pig can be tracked in real time, if the pig stops moving an alert can be generated and the location of the pig will be known.
