Title: Facsimile data transmission over a low data rate network with fill bit removal and reinsertion
Inventor: GROB MATTHEW S
IPC: H04M11/00
Filed: 1994-11-15
Abstract: System and method for minimizing data bottlenecks in Low Data Rate Networks (LDRNs) that communicate facsimile transmissions. An LDRN is a facsimile network having a transmission data rate less than the data rate of the FAX machines serviced by the network. The system and method can be implemented in any type of LDRN, including analog and digital wired LDRNs, as well as analog and digital wireless (e. g., cellular) LDRNs. The system and method involve processing the facsimile transmissions in order to make the data rates of the LDRN and the FAX machines compatible, thereby minimizing any potential facsimile data bottlenecks that may occur in the LDRN due to its slower data rate.

Abstract: A process for preparing boratabenzene derivatives is provided. The process includes the hydrogenation of a compound containing a boranaphthalene functional group to form a boratabenzene-containing compound. Depending on the compound containing a boranaphthalene functional group, the resulting boratabenzene compound may be converted into a catalyst suitable for olefin polymerization. A process for forming a boratabenzene derivative from a halo-dioxaborolane is also provided. In this process, a halo-dioxaborolane is reacted with a piperylide salt for form a pentadienyl dioxaborolane. The pentadienyl-dioxaborolane is reacted with a strong base to form an intermediate boratacyclohexanediene salt. The intermediate boratacyclohexanediene salt is then reacted with a trialkylaluminum compound to form an alkylboratabenzene salt.

Title: Rotor blade for a wind power installation
Inventor: WOBBEN ALOYS
IPC: F03D11/00
Filed: 2001-12-20
Abstract: The present invention concerns a rotor blade for a wind power installation and a wind power installation comprising at least one rotor blade according to the invention.   The smaller the surface area on which the wind acts, that is to say in particular the rotor blade area, the correspondingly lower is the load level for which the installation has to be designed and the correspondingly more easily can the rotor blade be transported. On the other hand the size of the wind power installation entails minimum dimensions which are unavoidable for operation and below which the installation dimensions may not fall.   In order to provide a rotor blade which on the one hand has the aerodynamically required surface area but which on the other hand is so designed that the surface area of the rotor blade and therewith the depth thereof can be reduced in predetermined situations a part of the surface of the rotor blade is deformable or movable.

Title: Method and apparatus for correcting crosstalk and spatial resolution for multichannel imaging
Inventor: FROST KEITH
IPC: G06T5/00
Filed: 2002-04-24
Abstract: A multichannel imaging system generates an ensemble of images for each field of view of an object (401). Each image in the ensemble is intended to contai n information from only one source among a plurality of sources for the object . However, due to crosstalk, at least a portion of the signal from a first source appears in a channel intended for a second source (404). Because the accuracy of the correction will be degraded if the images in an ensemble are spatially misaligned with respect to one another, the spatial offset between images is determined (408) and a correction is applied to substantially eliminate the offset. Then, a correction to the signals is determined to substantially reduce the contributions to the signal in a channel from the signals in other channels. The signal processing can be employed to process the output signals for each of a plurality of different disclosed imaging systems (409).

Patent CA-2460768-A1 (CA)
Inventor: HOILE CEFN RICHARD
IPC: H04L12/721
Filed: 2002-10-11
Abstract: In a communications network environment, nodes, such as personal computers, are assigned co-ordinates in a co-ordinate space (200) which is independent of network address and physical location. Each node (100) maintains links to a limited set of other nodes by storing the network addresses for those selected nodes. Each stored network address represents a link (205) in co-ordinate space (200). It becomes possible for any node to obtain the network address for a target node by initiating a query message to a node it has the network address for, which query message is propagated through the network between nodes which have the network address for a next node across co-ordinate space.  When a receiving node finds it is the target node, or is as close in co-ordinate space as it is possible to forward the query message, it returns its own network address to the initiating node. Embodiments of the invention can also be used to retrieve information other than network addresses - such as objects.
