Title: Improved gauge instrument for use in a motor vehicle
Inventor: BLOSSOM THOMAS
IPC: B60K35/00
Filed: 1998-11-03
Abstract: An eyes-up instrument (10) having a transparent display (16, 54, 60) is disclosed which is mountable on or above the dashboard (55) of a vehicle to allow the instrument to be read by a vehicle operator without lowering his eyes (85) to the vehicle instrument panel. The display of the instrument is transparent and therefore does not interfere substantially with the view of the operator. The compact design of the instrument and use of a miniature crossed coil gauge (24, 52, 68, 70, 72, 74, 84) supported in the display itself allow it to be mounted unobtrusively on a dashboard even in applications where transparency is not required.

Patent CA-2313169-A1 (CA)
Inventor: ABOODY KAREN
IPC: A61K35/12
Filed: 1999-09-17
Abstract: One of the impediments to the treatment of some human brain tumors (e.g., gliomas) has been the degree to which they expand, migrate widely, and infiltrate normal tissue. We demonstrate that a clone of multipotent neural progenitor stem cells, when implanted into an experimental glioma, will migrate along with and distribute themselves throughout the tumor in juxtaposition to widely expanding and aggressively advancing tumor cells, while continuing to express a foreign reporter gene. Furthermore, drawn somewhat by the degenerative environment created just beyond the infiltrating tumor edge, the neural progenitor cells migrate slightly beyond and surround the invading tumor border. When implanted at a distant site from the tumor bed (e.g., into normal tissue, into the contralateral hemisphere, into the lateral ventricles) the donor neural progenitor/stem cells will migrate through normal tissue and specifically target the tumor cells. These results suggest the adjunctive use of neural progenitor/stem cells as a novel, effective delivery vehicle for helping to target therapeutic genes and vectors to invasive brain tumors that have been refractory to treatment.
Patent CA-2314275-A1 (CA)
Title: Forward performance monitoring cell generation in atm oam processing
Inventor: NORTHCOTT PHILIP LYON
IPC: H04L12/56
Filed: 2000-07-19
Abstract: The invention facilitates insertion of forward performance monitoring cells into a processing queue coupled to an access controller.      A plurality of ATM cell input sources are coupled to the access control-ler. Each input source supports a plurality of ATM connections. The access controller controllably admits cells from the input sources into the processing queue. The cells are output from the processing queue on one of a plurality of output queues. Each forward performance monitoring cell contains statistics, including a count of the cells which correspond to one of the ATM connections and which are output through the processing queue. The processing queue is monitored to detect and maintain, for each ATM connection, a count of the total number of cells which pass through the processing queue and which correspond to that ATM connection. In accordance with the invention, before a forward performance monitoring cell corresponding to a particular ATM connection is inserted into the processing queue, an interim cell corresponding to that ATM connection is first transmitted to the access controller, which controllably admits the interim cell into the processing queue. The processing queue is monitored to detect the presence of the interim cell in the processing queue, without interrupting maintenance of the aforementioned counts for the respective ATM connections. Then, while the interim cell remains within the processing queue, the count for the ATM connection corresponding to that interim cell is stored in the interim cell, thereby converting the interim cell into the desired forward performance monitoring cell.

Title: Adjustment of a pickup reel of a crop harvesting header
Inventor: FOX THOMAS RUSSELL
IPC: A01D57/04
Filed: 2000-09-22
Abstract: ABSTRACT OF THE DISCLOSURE        A crop harvesting header includes a reel mounted on a pair of forwardly and downwardly extending arms carried on a header frame above a table and cutting knife. The reel is rotatable about a longitudinal axis and includes angularly bats. The arms can be raised and lowered by hydraulic cylinders to raise and lower the reel. A linkage including a cable and bell crank is provided which is responsive to the forward and downward sliding movement of the main elongate beam along the support arms for simultaneously and automatically causing a raising movement of the reel support arms. The cable is slack over a rearward part of the movement so that no lifting occurs. The linkage is arranged relative to a forward and downward slope of the arms such that, over the forward part of the movement, the beam moves substantially horizontally to cause the reel to move forwardly of the knife without moving downwardly into engagement with the ground, for operating with the knife at ground level. The linkage is arranged to be readily dis-engageable by disconnecting the cable such that, when disengaged, the reel support arms are not raised as the beam undergoes the forward sliding movement for operating where the knife is raised above the ground.

Title: Gain control and shaping of edfas via dual cavity gain control
Inventor: KROL MARK F
IPC: H04B10/572
Filed: 1999-09-16
Abstract: The present invention relates to an optical amplifier system in which multip le laser cavities are utilized to control the gain of an erbium doped fiber amplifier (EDFA). More specifically, the present invention is directed to an  optical amplifier comprising a gain medium such as an erbium doped optical fiber which provides gain for an optical signal propagating therein. The gai n medium also provides gain for a plurality of laser cavities (e.g. first and second laser cavities) which simultaneously oscillate at individual (e.g. first and second) wavelengths. The inventive optical amplifier results in reduced variation in gain spectrum as a function of input signal power, as a  function of wavelength, and as a function of time. By varying the optical attenuation in one or more of the individual laser cavities it is possible t o vary the gain spectrum of the gain medium at the corresponding individual wavelength and this controls the shape of the gain spectrum of the gain medi um.
