Patent CA-2516241-A1 (CA)
Title: Ski clamp
Inventor: MOLLER WOLFGANG
IPC: A63C11/02
Filed: 2003-05-02
Abstract: The invention relates to a ski clip, which is used to fasten ski poles (6a, 6b) to skis (7). In general the simultaneous transport of a pair of skis (7) and a pair of ski poles (6a, 6b) poses problems as the use of both hands is required. It is therefore difficult to simultaneously hold the skis (7), ski poles (6a, 6b) and other objects or to hold onto retaining bars in buses and gondolas when transporting skis (7). The disadvantage of attachments for solving said problem in prior art is that the ski pole holders have to be stored separately when not in use and in addition are inconvenient to use. The invention solves said problem by the permanent attachment of a fixing device (1a, 1b) to the ski pole (6a, 6b), whereby a forked clamping piece (5a, 5b) that can be folded out is fastened to said fixing device and a pair of skis (7) can be clamped between the limbs (9) of said piece. By attaching a forked clamping piece (5a, 5b) to each side of a pair of skis (7), not only are the ski poles (6a, 6b) fastened to the skis (7), but the skis (7) are also held together. This permits the skis (7) and ski poles (6a, 6b) to be transported in one hand.

Patent CA-2527716-A1 (CA)
Inventor: LIU LINA
IPC: G02B1/04
Filed: 2004-05-28
Abstract: Composite interpenetrating network (IPN) of PDMS and PNIPAAM was formed to generate polymers with oxygen and glucose permeability as well as improved wettability compared to PDMS homopolymers and greater mechanical strength than PNIPAAM homopolymers. Transparent vinyl and hydroxyl terminated PDMS / PNIPAAM  IPNs (PDMS-V and PDMS-OH IPNs respectively) were successfully synthesized.  Transmission electron microscopy images verified the structure of the IPNs.  Surface analysis suggested that PNIPAAM was present on the surface as well as in the bulk material. PDMS-OH IPNs generated from a PDMS-OH matrix cured in the presence of solvent had the highest glucose permeability at 10-7 cm2/s, comparable to that of the native cornea. The LCST phenomenon remained in these materials, although changes were not as abrupt as with pure PNIPAAM. These results suggest that these materials may be further developed as ophthalmic biomaterials or for controlled drug release applications.

Abstract: The invention relates to a system and method for gathering data for use in a spoken dialog system. An aspect of the invention is generally referred to as an automated hidden human that performs data collection automatically at the beginning of a conversation with a user in a spoken dialog system. The method comprises presenting an initial prompt to a user, recognizing a received user utterance using an automatic speech recognition engine and classifying the recognized user utterance using a spoken language understanding module. If the recognized user utterance is not understood or classifiable to a predetermined acceptance threshold, then the method re-prompts the user.  If the recognized user utterance is not classifiable to a predetermined rejection threshold, then the method transfers the user to a human as this may imply a task-specific utterance. The received and classified user utterance is then used for training the spoken dialog system.
