Title: Methods and compositions for the modulation of host immune response to allergens
Inventor: BALDWIN ROBERT W
IPC: A61K39/00
Filed: 1993-03-10
Abstract: The present invention provides novel compositions and methods useful in the modulation or selective suppression of host immune responses to an immunogen of interest, particularly to immunogens which are exogenous antigens or allergens. Subject compositions include antibody, antibody derived, and antibody-like molecules of primary antigen reactivity with respect to the immunogen of interest. Antibodies or antibody-like or antibody-derived molecules include antibody fragments such as Fab, and complementarily determining region peptides (CDRs) which may be grafted into a framework region of any species, particularly human. They also include human antibodies, derived from sensitized human lymphocytes produced by cell fusion with heterohybridomas, or by DNA cloning and expression. Other compositions include T cell receptor (TCR) molecules, obtained either from T cell clones or hybridomas or as purified TCR preparations. Immunoreactive peptides corresponding to some or all of the complementarily determining regions or hypervariable regions of the TCR are also employed.
Patent CA-2132605-A1 (CA)
Inventor: BELL DOUGLAS W
IPC: F16N19/00
Filed: 1994-09-21
Abstract: A clutch assembly for a vehicle with selective front wheel drive includes an automatic oil level control system. The clutch assembly includes a housing which encloses a hydraulic clutch. The hydraulic clutch, when engaged, connects a front wheel drive shaft to a main vehicle drive shaft. Since the hydraulic clutch has a tendency to leak fluid into the housing, the fluid level within the housing is controlled by pressurizing the housing via compressed air from a turbocharger or the like. A pair of blow back tubes extend into the housing from opposite sides of the housing, and are interconnected and then connected to an unpressurized reservoir, such as the crankcase or transmission case, via an excess oil evacuation line. The blow back tubes have open ports which are positioned such that, when oil simultaneously covers the ports in both blow back tubes, excess oil is evacuated to the connected reservoir. The blow back tube ports are positioned such that excess oil is detected and evacuated when the clutch and drive shaft are static or dynamically rotating.

Abstract: Afin de réduire l'effet des parasites lors de la réduction des données d'un signal audio dont les données sont déjà réduites ou bien lors d'une toute première réduction des données d'un signal audio, en tenant compte des violations de code, il est suggéré, en cas de surcharge de codes, de sélectionner un code permettant d'obtenir la meilleure répartition de l'effet des parasites quant à la qualité de restitution. Le signal audio peut être modifié notamment avant le codage dans son comportement dans le temps et/ou dans sa répartition spectrale, selon un modèle d'adaptation choisi, sans altérer pour autant de manière subjectivement perceptible le signal après décodage.
Patent CA-2135240-A1 (CA)
Title: Automated license plate locator and reader
Inventor: ALVES JAMES F
IPC: G06V10/32
Filed: 1994-11-07
Abstract: An automated license plate locator and reader (10) which provides novel methods for 1) correcting for perspective distortion (16), 2)  locating the license plate (20), 3) reading the license plate (22) and 4) improving the confidence rating of the output signal (228).  The novel method for accommodating a wide range of viewing geometries involves warping the image to eliminate perspective distortion of the plate resulting from roadside camera placement.  The novel method for locating plates involves correlating an "idealized" edge template of a license plate with an edge-enhanced version of the image.  Edge enhancement and shadow reduction is achieved by applying a Laplacian operator over the input image.  Performance is further improved by filtering out distracting edges within the resulting correlation surface and then locating the highest peaks within this filtered correlation surface.  The location of the highest peaks provides the location of the plate.  The novel method for reading the license plates involves performing a modified binary correlation of an image of the plate with reference characters to provide output signals indicative of the symbols on the plate.  This output is correlated with valid license plate signals to improve the confidence rating thereof.

Title: Output buffered packet switch with a flexible buffer management scheme
Inventor: WIDJAJA INDRA
IPC: H04L12/56
Filed: 1993-05-21
Abstract: An output-buffered packet switch with priority packet transmission and a flexible buffer management scheme is disclosed. The switch consists of a sorting network at the input, a nonblocking routing network at the output, and multiple modules of co-lumn-fill networks together with the storage elements connected in series to provide a novel buffer management scheme. Each module provides one dedicated buffer for each output port, except the last module where the storage is shared by all the outputs. The combination of dedicated and shared buffering gives high performance for a wide range of traffic conditions. The switch is expandable in the sense that its performance can be enhanced by simply adding more modules. The switch design is distributed and has self-routing capabilities, so it can operate at very high data rates. The output-buffered packet switch can be used to imple-ment a centralized control for another packet switch of higher speed but same functionality.

Title: Moveable manhole cover
Inventor: PETTESCH MARTIN C
IPC: E02D29/14
Filed: 1995-10-10
Abstract: A manhole includes a carriage mounted on the underside of the cover that cooperates with a supporting guide channel located across the mouth of the manhole. the guide channel can be rotated to an incline so that the carriage can easily roll onto and from the supporting guide member. The free end of the guide channel is raised and lowered by a standard ratchet wrench inserted through the cover so that the operator need not lift any part of the cover manually. Once raised to the ready position, the operator simply pulls laterally on the cover handle to roll the cover slightly upward and laterally from the manhole opening. Once the cover clears the manhole, the guide channel can be rotated up and outward to provide access to the entire manhole area , if desired. To replace the cover, the guide channel is rotated to again extend across the manhole, the cover/carriage assembly is rolled laterally on to the guide channel until the cover edge contacts the ring edge. The channel is then lowered with use of the tool to seat the cover on to the manhole ring. The operator at no time manually lifts the cover. The guide channel precisely orients the cover when moved to the closed position.
