Filed: 2002-03-07
Abstract: Selon cette invention, une surface d'un canal, d'un caniveau ou d'un tuyau est revêtue à l'aide d'un composite polyuréthanne/géotextile. Une composition polyuréthanne qui ne s'affaisse pas est appliquée sur la surface du canal, du caniveau ou du tuyau, un géotextile est mis en contact avec cette surface de manière à ce que ledit géotextile s'imprègne de la composition polyuréthanne qui ne s'affaisse pas, cette dernière durcissant pour former un composite polyuréthanne/géotextile. Le polyuréthanne qui ne s'affaisse pas est un produit de réaction d'un polyisocyanate, d'un composé polyhydroxyle à poids moléculaire élevé et d'un composé possédant au moins deux groupes amino. Un diol ou un triol à poids moléculaire faible, une charge et un catalyseur constituent des composantes éventuelles. Ces composites sont particulièrement utiles pour revêtir des surfaces anguleuses ou concaves fissurées ou brisées.

Title: Buffer circuit having reduced leakage current and method of reducing leakage current in a field programmable device
Inventor: KAVIANI ALIREZA S
IPC: H03K19/177
Filed: 2002-02-20
Abstract: A technique for reducing leakage current in static CMOS devices by adding additional transistors in series between selected inverters and ground or power. NMOS and PMOS transistors are added to selected buffers comprised of two inverters in series. The PMOS transistor (124) is connected between the first inverter (112,114) and power (Vdd) and the NMOS transistor (126) is connected between the second inverter (128) and ground. The added transistors are controlled by a memory cell (130) to be on when the buffer is being used and off when the buffer is unused. Alternatively, no PMOS transistor is added and an existing PMOS transistor of the first inverter is manufactured to sit in a Vgg well. The same tech niques are employed with selected buffer pairs.

Inventor: FORD JAMES R
IPC: A01K85/01
Filed: 2003-11-20
Abstract: A disposable, buoyant, scented fishing lure is formed of a soft, resilient, economically disposable plastic material, with a hollow chamber formed within the lure body. A fish attractant scent material and flotation element are placed within the lure body chamber. The float may be coated or otherwise treated with the scent material prior to installation within the lure, to install the scent material therein.      The chamber, with the scent material and float installed therein, is then hermetically sealed to prevent escape of the scent therefrom.      When the lure is to be used, the angler installs a fish hook therein and penetrates the scent and float chamber with the hook. This allows the scent material to be released gradually from the lure through the passages formed by the hook insertion in the lure. Once the scent material has substantially dissipated, the angler may discard the used lure for a fresh one.

Abstract: The seasoning applicator (100) applies seasoning onto snack food products (108) such as potato chips, corn chips, tortilla chips, and the like in a two-dimensional seasoning pattern. A two compartment sifting assembly (110) has a first top layer having a screen (122) where seasoning is initially deposited.  Upon vibration, the seasoning is passed through the top layer screen into a lower compartment. Therein, the seasoning is further distributed across the surface of the lower layer screen (132), which generally has a screen with smaller openings than the top layer screen. This promotes the even distribution of seasoning through the lower screen. Thereby, a two-dimensional seasoning pattern is created for depositing on a moving bed (170) of snack food products.

Abstract: A communication network system has a plurality of sub-networks interconnected to one another, at least one mobile node having a care-of address dependent on a sub-network currently connected thereto and a home address independent of the connected sub-network, and a home agent.     Upon detection of a sub-network to which the mobile node is connected, the mobile node determines a security method corresponding to the sub-network from among security methods held in a node-side security application management table as a security method used for ensuring the security for user data communicated between the mobile node and a home agent associated therewith. Then, the sub-network is notified to the home agent through a mobile node network signal. The home agent determines a security method corresponding to the sub-network from among security methods held in an agent-side security application management table as a security method used for ensuring the security for user data communicated between the home agent and the mobile node managed thereby.

Abstract: A catheter for use in neurosurgery is described. The catheter has a fine tube arranged for insertion into the brain parenchyma of a patient with an external diameter of not more than 1.0 mm, a hub and a stop surface operatively connecting the single fine tube and the hub, the stop surface allowing a distal end of the fine tube to be located at a desired target during insertion of the fine tube into the brain parenchyma. The catheter may be used in stereotactically targeting treatment of abnormalities of brain function, and for the infusion of therapeutic agents directly into the brain parenchyma. This is advantageous when a therapeutic agent would have widespread unwanted effects which could be avoided by confining the delivery to the malfunctioning or damaged brain tissue.
