Patent CA-2244624-A1 (CA)
Inventor: OSTERMANN JOERN
IPC: G10L21/06

Abstract: According to MPEG-4's TTS architecture, facial animation can be driven by two streams simultaneously - text, and Facial Animation Parameters. In this architecture, text input is sent to a Text-To-Speech converter at a decoder that drives the mouth shapes of the face. Facial Animation Parameters are sent from an encoder to the face over the communication channel. The present invention includes codes(known as bookmarks) in the text string transmitted to the Text-to-Speech converter, which bookmarks are placed between words as well as inside them. According to the present invention, the bookmarks carry an encoder time stamp. Due to the nature of text-to-speech conversion, the encoder time stamp does not relate to real-world time, and should be interpreted as a counter. In addition, the Facial Animation Parameter stream carries the same encoder time stamp found in the bookmark of the text. The system of the present invention reads the bookmark and provides the encoder time stamp as well as a real-time time stamp to the facial animation system. Finally, the facial animation system associates the correct facial animation parameter with the real-time time stamp using the encoder time stamp of the bookmark as a reference.

Title: Skin vibration method for topical targeted delivery of beneficial agents into hair follicles
Inventor: LI LINGNA
IPC: A61B17/20
Filed: 1997-11-10
Abstract: The present invention provides methods and apparatuses for use in providing rapid, selective and effective targeted delivery of beneficial substances into hair follicles by use of a vibrator (1) for vibrating a chamber with a substance (2) to be delivered to the skin (3). The invention relies on the use of a vibrational method of delivery of substances of different size from small molecules up to particles compatible with the diameter of hair strand into the hair bulb. The skin is subjected to the vibration of about 1 Hz to about 100 Hz frequency, and 0.1 mm to about 10 mm amplitude, an amount which is sufficient to cause mechanical shifts in different directions of skin structure without damage. This results in follicle effective uptake of the tested substances such as carbon particles of different size as well as melanin. The methods and apparatuses of the present invention are particularly useful in conjunction with photosensitizing agents and electromagnetic irradiation. Such a combination is used to target the delivery ofagent within hair follicles and then subsequently activate the agent.

Patent CA-2275914-A1 (CA)
Inventor: MAILAENDER LAURENCE EUGENE
IPC: H04B1/7107
Filed: 1999-06-22
Abstract: A method and apparatus for increasing system capacity in a mixed-rate wireless communication are disclosed. Improvements are obtained using multiuser detection or antenna array processing techniques or both to explicitly cancel or attenuate only the high power users. Multiuser detection may be combined with antenna array processing to recover capacity appropriated by the high-power users. By mitigating the interference effects of only the high-powered users, the computational burden is manageable. An antenna array algorithm or a multiuser detection algorithm or both, are applied only to n high rate users (n < k total users). In an antenna array processing implementation, fewer antennas may be employed (one for each high-rate user).  In a multiuser detection implementation, fewer cancellation stages may be employed (one for each high-rate user).

Patent CA-2282929-A1 (CA)
Inventor: VAUGHAN BRIAN J N
IPC: H04L12/56
Filed: 1999-09-21
Abstract: A method and apparatus for reduction of call setup rate in an ATM network are described. The method and apparatus are particularly useful in ATM networks used for the transfer of bearer traffic between telephone switching offices. The method involves caching a number of switched virtual circuits (SVCs) between edge interfaces to the ATM network. A cache connection is an emulated circuit between two edge interfaces that is available and idle. The apparatus provides a central policy manager which computes and distributes cache policies to cache managers located in the edge interfaces. The cache managers manage pools of cached SVCs established between two edge interfaces. The method and apparatus reduces the number of connection setup requests sent to the ATM switches. The advantage is the ability to use ATM switches which have slow connection setup rates to provide commercially acceptable telephone services in an efficient manner. The method can also be used with fast ATM switches when they become available to balance the use of bandwidth and switch resources to reduce overall cost.
