Patent CA-2294201-C (CA)
Inventor: BERNAUER CHRISTOF
IPC: H02P6/14
Filed: 1998-06-08
Granted: 2003-12-02
Abstract: The invention relates to an electronically commutated motor having a stator carrying a plurality of winding strands and a rotor in which the individual winding strands are controlled via power amplifiers in staggered periods of time, the periods being subdivided into control time and idle time. In order to reduce the power loss in the power amplifiers and consequently to increase the efficiency specifically in the range of high currents, the invention provides that the control times are subdivided into an initial time segment and a final time segment-and that at low motor currents pulsing occurs only in the initial or final time segments in pulse width modulation, while at high currents complete switching through takes place in the initial time segments and additionally in the final time segment for a more or less long period of time or in the final time segments and additionally in the initial time segments for a more or less long period of time.

Abstract: In a cellular mobile radio system, co-channel radio base stations are provid ed with a time reference signal being a synchronizing signal or a time reference from another co-channel radio base station. Each co- channel radio base station (708, 712) is also provided with a radio base station specific time offset (720, 722) differing between the c o- channel radio base stations by at least a predetermined value which prevents known sequences in desired signals and known sequences in interfering signals from overlapping in a disturbing way at reception. In each co-channel radio base station the time reference signal a nd the radio base station specific offset are used for the timing of sending bursts downlink from the co-channel radio base stations towards mobile radio stations. Each radio base station has functions receiving the time reference signal, storing the time offset and using the time reference signal and the time offset for the timing of the burst termination on the downlink (720).

Abstract: La présente invention concerne des compostions et des méthodes de transport ou de libération d'agents thérapeutiques et diagnostiques ou de métabolites ou autres analytes à partir de cellules, de compartiments cellulaires, ou à travers des couches ou des barrières cellulaires. Ces compositions contiennent un agent améliorant le transport à travers les barrières membranaires et sont généralement administrées en association avec un activateur et/ou une exposition à un stimulus, afin de provoquer une rupture ou pour modifier la perméabilité, le transport ou la libération. Dans un mode préféré de réalisation, ces compositions contiennent des composés qui provoquent la rupture des membranes endosomiques en réaction au faible pH des endosomes, mais qui sont relativement inactives face aux cellules membranaires, couplées directement ou indirectement à un agent thérapeutique ou diagnostique. On peut également utiliser d'autres agents de rupture, sensibles aux stimuli et/ou aux activateurs autres que le pH, tels que la lumière, les stimuli électrique, électromagnétique, les ultrasons, la température ou une association de ces stimuli. Par ailleurs, on peut coupler ces composés à un agent devant être administré ou à un ligand formant un complexe avec cet agent, par liaison ionique, covalente ou par liaison H. Les agents à administrer peuvent être des agents thérapeutiques et/ou diagnostiques, les traitements améliorant l'administration tels que les ultrasons, l'iontophorèse, et/ou l'électrophorèse pouvant être également utilisés avec les agents de rupture.

Title: Channel code configurations for digital audio broadcasting systems and other types of communication systems
Inventor: LANEMAN JERRY NICHOLAS
IPC: G10L19/005
Filed: 2000-12-06
Granted: 2004-08-17
Abstract: Improved channel code configurations for use in transmission of digital audio or other types of information in a digital communication system. The channel code may include an outer channel code, e.g., a cyclic redundancy code (CRC), and an inner channel code, e.g., a complementary punctured pair convolutional (CPPC) code. In accordance with the invention, multiple code words of the outer code are associated with a given packet of the digital information, in accordance with a particular outer code configuration, so as to provide partial error flagging for different portions of the given packet. An information encoder, e.g., a PAC encoder, interacts with an outer code encoder to determine a bit allocation for transmission of packets at a particular bit rate, based at least in part on the outer code configuration. The invention is particularly well-suited for use in the transmission of digital audio information in a hybrid in-band on-channel (HIBOC) digital audio broadcasting (DAB) system, but is also applicable to other types of information and other types of communication systems.

Title: Large round baler
Inventor: VIAUD JEAN
IPC: A01F15/07
Filed: 2001-02-07
Granted: 2005-07-12
Abstract: The technical problem to be solved is that of providing a non-stop, large round baler that has a weight that is less than known non-stop, large round balers. This problem is solved by a structure which includes separate upper and lower baling chamber sections, with the upper baling chamber section being designed to form a major portion of a baling chamber and being mounted to opposite baling chamber walls for moving fore-and-aft together with the walls between a rear location, wherein it cooperates with the lower baling chamber section to define a rear baling chamber, and a forward location wherein it cooperates with the lower baling chamber section to define a front baling chamber. During the time after a bale has been completed by the rear baling chamber and the upper baling chamber section is moving from the rear to the forward location, a crop feed rotor that is located at the lower baling chamber section is operated in reverse so that crop is accumulated in a zone wherein it becomes housed by the front baling chamber when the upper baling chamber section reaches its forward position. In the meantime, the formed bale may be deposited onto the ground, or wrapped with sheet or net material and then deposited onto the ground.

Abstract: A method by which immune responses to cortical bone grafts and other substrates (e.g., cement, 1PN, etc.) can be minimized and at the same time graft osteoinductive potential can be improved, and improved graft substrate materials are disclosed. The method of the invention provides new types of bone grafts that incorporate into host bone more thoroughly and more rapidly, eliminating long-term complications, such as fracture, non-union, infection, and rejection. In the method of the invention, bone grafts or other substrates are modified to have an osteoinductive surface modification that the recipient's body will accept as its own tissue type and therefore will not reject or otherwise cause to fail. The osteoinductive surface modification comprises a biopolymer matrix coating that is seeded with periosteal cells that have been previously harvested either from the graft recipient or from an allogenic or xenogenic donor source.
