Title: Methods of treating type i hypersensitivity using monophosphoryl lipid a
Inventor: MARSHALL JEAN S
IPC: A61K39/00
Filed: 1997-05-08
Abstract: Methods and compositions for treating type I immunoglobin E (IgE)-dependent hypersensitivity by the administration of monophosphoryl lipid A(MLA) or 3-deacylated monophosphoryl lipid A (3D-MLA) are disclosed. MLA or 3D-MLA administered alone or in combination with an allergen to a patient suffering from type I  hypersensitivity reduces levels of total or allergen specific IgE and increases levels of IgG antibody in that patient. MLA and 3D-MLA can be administered as part of a desensitization regimen or as a component of a prophylactic vaccine to prevent a type I hypersensitivity reaction.

Abstract: Known laryngeal mask assemblies have an inflatable cuff mounted at the patient end of a tube. In the present invention the cuff has a region on its anterior surface and a region on its posterior surface that expand preferentially when gas pressure is increased. The cuff is inflated for insertion at low pressure such that the cuff takes one shape and is then further inflated when positioned correctly such that the region on the anterior surface expands and engages the epiglottis and such that the region on the posterior surface expands and engages the adjacent tissue, pushing the anterior surface forwardly.

Title: Dynamic echo canceller and parameter selection in telephony systems
Inventor: ORTOLANIS PETROS
IPC: H04B3/23
Filed: 1998-01-15
Abstract: An echo canceller pool configuration (110) is provided that allows a user (102) to predetermine and individualize the echo cancellation parameter settings (Fig. 8) for any echo canceller in the pool, based on prior knowledge of the echo path characteristics of the specific transmission route to be used for an ensuing call. The echo canceller with the individualized parameter settings is then switched into that route for the duration of the call. For example, at call setup, once a trunk route has been identified that will be used to complete the call, a "flag" is retrieved that is associated with that specific route. That "flag"  identifies specific echo canceller parameter settings to be used for that route. Those parameter settings are downloaded to the echo canceller device selected from the pool (110), and that device is then switched into the specific trunk involved.

Title: Downhole packer
Inventor: ARIZMENDI NAPOLEON
IPC: E21B33/128
Filed: 1998-02-03
Abstract: A packer for sealing a space downhole in a well. The packer comprises a deformable sheath (16) having a body (22) and first and second ends (18, 20) for defining an interior volume (24) proximate a tool surface (12). A material located within the interior volume (24) is deformable, when the sheath second end (20) is moved toward the sheath first end (18), to move the deformable sheath (16) into the downhole space. The sheath (16) can function as a sealing element or a backup element, and can be applied to different structures and tool configurations downhole in a wellbore (32). For example, the packer can be applied to plugs, to through tubing mandrels, and to other well tools in open hole or cased wellbore configurations. The packer resists damage to the seal elements (48), provides confirmation of the packer setting force (F1), an d is less expensive than conventional packer designs.

Title: Window regulator mechanism
Inventor: SMITH PETER J
IPC: E05F1/16
Filed: 1998-05-06
Abstract: The present invention is a window regulator mechanism for vertically moving a window panel mounted within a motor vehicle door. The mechanism comprises an elongated guide rail member (18) mounted within the vehicle door and having a base portion (66) with a pair of side flange portions (56, 62). A first of the pair of side flange portions (56, 62) has a nose portion (60) extending laterally outwardly therefrom. A second of the pair of side flange portions (56, 62) has a convex exterior surface (84). A window moving structure (17) engages the window panel and has a base member and a pair of side leg portions (48) extending from opposing sides thereof. One of the side leg portions has a nose-receiving groove (58) formed in an inwardly facing surface thereof. The window moving structure is slidably mounted on the guide rail member. A  manually operable actuating mechanism is constructed to slidably move the window moving structure vertically along the guide rail member. The nose portion (60) of the guide rail member is received within the nose-receiving groove (58) of the window moving structure and the convex exterior surface (84) of the guide rail member (18) is slidably engaged with an inwardly facing surface (54) of another of the side leg portions (48) of the window moving structure (17) opposite the nose-receiving groove such that: a) relative pivotal movement between the guide rail member (18) and the window moving structure (17) about a fixed pivot axis (P) extending longitudinally through the nose-portion (60) is permitted and b) relative movement between the guide rail member (18) and the window moving structure (17) in a radial direction with respect to the fixed pivot axis (P) is substantially restricted to thereby reduce vibrations which occur as a result of forcibly moving the vehicle door into closing engagement with a motor vehicle body.

Title: System for programming field programmable devices
Inventor: SMILEY DAVID A
IPC: G06F17/50
Filed: 2000-03-27
Abstract: A system for programming field programmable devices (FPDs) of different types across different boards. An in-system programmable master (ISPM) communicates over a bus to in-system programmable slaves (ISPSs) on one or more boards. FPDs on each board are connected into chains of like type, and each chain is connected to an ISPS located on the board. The ISPM uses a packet protocol to communicate with all ISPSs in a system. Each packet comprises an ISPS address field, a chain select field, and a command field. Each ISPS reads packets addressed to it, and decodes and transmits the commands to the selected FPD chain in a protocol appropriate to the chain.
