Patent CA-2546696-A1 (CA)
Inventor: LI XINHUA
IPC: C08F20/00
Filed: 2003-11-19
Abstract: L'obésité chez l'homme est un problème de santé touchant une proportion considérable de la population américaine. De nombreuses méthodes de traitement de l'obésité ont été mises au point, mais elles représentent toutes de sérieux inconvénients. La présente invention concerne une nouvelle classe de polymères présentant soit un atome de souffre, soit un groupe de retrait d'électrons entre un squelette polymère et un groupe pendant d'aryl acide boronique. Les polymères, ayant un tel groupe de retrait d'électrons, se sont avérés être particulièrement efficaces dans l'inhibition de la lipase in vitro et in vivo. Font également l'objet de cette invention des méthodes de traitement de l'obésité et de réduction de l'absorption des graisses.

Title: Timing estimation in an ofdm receiver
Inventor: GUPTA ALOK KUMAR
IPC: H04L27/06
Filed: 2005-01-28
Abstract: A timing estimation system and methodology are provided. In particular, a first pilot is employed in conjunction with three acquisition stages. In the first stage, an attempt is made to observe the leading edge of the correlation curve associated with the first pilot symbol. In the second stage, a determination is made to confirm a leading edge was detected in the first stage by attempting to observe a trailing edge of the correlation curve.  Furthermore, during this second stage, a frequency loop is updated to account for frequency offset. The third stage is for observing the trailing edge of the curve if it was not already observed in stage two. Upon detection of receipt of the first pilot, a second pilot can subsequently be employed to acquire fine symbol timing.

Title: Data insertion techniques for expanding information capacity of existing communication systems
Inventor: LONG CHRISTOPHER
IPC: H04N7/08
Filed: 2005-04-15
Abstract: Methods and apparatus are described for inserting data in a communications system, such as in an existing analog communications system, using quadrature amplitude modulation (QAM) with in-phase analog signals and quadrature data signals. These methods can minimize the distortion to the analog signals while maximizing the data signal strength. The data signals may be sub-modulated on a subcarrier frequency (201) such that the data signals do not interfere with the analog signal detectors in the analog signal receivers, and may be processed with an abatement filter (202) to mitigate the distortion due to Nyquist mismatch in the receiver. The injection phase of data signals may be determined (206) by adaptive algorithms, using a monitor analog signal receiver (103).

Title: Roofing product possessing thermal expansion relief characteristics
Inventor: SHADWELL PETER J
IPC: E04D1/00
Filed: 2007-05-16
Abstract: A roofing member provides improved thermal expansion relief characteristics when mounted adjacent to other roofing members in laterally extending courses on a roof surface. According to one arrangement, the roofing member has a main body with top and bottom surfaces, and side regions, as well as one or more spacer tabs extending outwardly from one or more of the side regions. Each spacer tab extends outwardly from a location on one of the side regions that is adjacent to one of a set of depressions formed into the bottom surface of the main body. In this way, when thermal expansion of adjacently mounted roofing members occurs causing a compressive force to be applied against particular spacer tabs, the spacer tabs fail in a way that at least partially displaces the respective tabs into the adjacently positioned depressions, thereby reducing the stress loads that adjacent shingles apply to one another.
