Title: Diagnostic layer and methods for detecting structural integrity of composite and metallic materials
Inventor: LIN MARK
IPC: G01M99/00
Filed: 2000-11-02
Granted: 2010-01-05
Abstract: A diagnostic layer having a network of actuators and sensors may be incorporated into or on the surface of composite, metallic, and laminated materials for monitoring the structural health of th e material. The diagnostic layer is adapted for detecting and measuring changes in the condition of the material, e.g., the site and extent of damage in the material. In a preferred embodiment, piezoelectric devices are embedded in the diagnostic layer in a network, and serve as actuators and sensors. Signals emitted from the sensors in response to physical deformation, either by an impact or as a result of stress waves generated by the actuators, are diagnostic of the current condition of the diagnostic layer. The diagnostic layer is also adapted to monitor the curing process of a composite material and accurately determine when curing is complete. Methods for monitoring changes in conditions of a material are also disclosed.

Granted: 2004-04-27
Abstract: L'invention se rapporte à des dispositifs de distribution de matières volatiles telles que des insecticides. Des éléments de support de type table fournissent un compartiment pour la matière volatile. Une ou plusieurs structures de type pied de table font saillie vers le bas à partir du plateau de table de manière à maintenir une cavité présente dans le plateau de table au dessus d'un élément brûleur. Ceci se traduit par un chauffage plus modéré et uniforme qui permet une libération efficace de la matière volatile sur un laps de temps plus important. Dans certaines réalisations de l'invention, les structures de type pied de table et le plateau de table se présentent sous la forme de pièces distinctes qui permettent de mettre en oeuvre des processus de ventilation juxtaposés sous la matière volatile.

Abstract: A method and subscriber unit (SU) for using Maintenance Power Control (MPC) for wireless communication with a base station in a wireless communication system. The SU includes a transmitter, a receiver and associated MPC circuitry. When in an awake phase, the transmitter transmits signals to the base station. When in a sleep phase, the transmitter is configured to become periodically active to transmit a status signal to the base station. The receiver and associated MPC circuitry are configured to adjust a selected initial power lever downwardly when a reply signal is received, and upwardly when no reply signal is received within a predetermined time period of the transmission of the status signal. Thus, the selected initial power level is maintained at a level for efficient system communications.

Title: Genes of il-12p40 subunit mutated for improving the activity of il-12 and use thereof for dna vaccine adjuvant
Inventor: SUNG YOUNG CHUL
IPC: C12N15/09
Filed: 2001-03-15
Granted: 2012-08-07
Abstract: The present invention relates to the IL-12p40 subunit mutant gene which can produce IL-12 (interleukin 12) of human and mouse origin with high activity, the expression vector including above mutant gene and the use of them to DNA vaccine adjuvant. Particularly, it relates to IL-12p40 mutant gene which inhibits the secretion of IL-12p40 but normally secretes active IL-12p70 by making mutation at Asn-222 (human) or Asn-220 (mouse) amino acid of IL-12p40, which acts competitive inhibitor of active form of IL-12, IL-12p70. Therefore, the IL-12p40 mutant gene of the present invention can be useful for DNA vaccination and gene therapy to various diseases, for example, AIDS, hepatitis C or hepatitis B, cancer, influenza, tuberculosis and malaria, which essentially require cellular immune responses for thier therapy.

Abstract: A first embodiment of a drive arrangement for a large rectangular baler includes hydraulic pump and motor sets, and second and third embodiments include only gear and shaft arrangements, for driving the plunger for compressing the crop being baled, and for driving all of the auxiliary functions. In all embodiments, power delivered by a main shaft is divided between an auxiliary function drive shaft and a plunger drive shaft. In the first and second embodiments, a flywheel is located for smoothing the power flow to the plunger drive arrangement, and in the third embodiment the flywheel is located for smoothing power flow to both the plunger drive arrangement and the auxiliary function drive arrangement. In all embodiments, the rotation of the shaft carrying the flywheel due to the inertia of the flywheel is ineffective for driving the plunger and auxiliary function drive arrangements when power to the main drive shaft is cut off.

Title: Box for domestic animals, particularly sows
Inventor: RASMUSSEN HENRIK
IPC: A01K1/02
Filed: 2001-10-17
Granted: 2010-01-12
Abstract: A box for domestic animals, preferably sows, e.g. for individual feeding of the animals. The box (1) accommodates one animal and comprises a feed trough at the front end of the box, a front gate (5) hinged about a vertical axis and a rear gate (3) hinged about a horizontal axis (14) in order to be pivoted to open position at a level above the back of the animal. The front gate (5) may block the access to the feed trough when the rear gate (3) is open, while the rear gate (3) in the closed position prevents access to the inner of the box (1) while the front gate (5) is open. A connecting means (12) interconnects front and rear gates (5; 3) so that opening one of the gates causes closing of the other. The suspension of the rear gate (3) with horizontal axis of pivot enables lifting the gate (3) up above the reach of the animals, thus preventing an animal outside the box (1) from accidentally closing the rear gate when in open position.

Abstract: The present invention provides a method of treating a wellbore penetrating a subterranean formation with a treatment fluid whereby fine particulate flowback is reduced or prevented. The method includes the steps of providing a fluid suspension including a mixture of a particulate coated with a tackifying compound, pumping the suspension into a subterranean formation and depositing the mixture within the formation whereby the tackifying compound retards movement of at least a portion of any fine particulate within the formation upon flow of fluids from the subterranean formation through the wellbore. Alternatively, the tackifying compound may be introduced into a subterranean formation in a diluent containing solution to deposit upon previously introduced particulates to retard movement of such particulates and any fines subject to flow with production of fluids from the subterranean formation.

Title: Character table implemented data compression method and apparatus

IPC: G06F17/30
Filed: 2002-04-15
Granted: 2010-04-06
Abstract: A new LZW compressor implementation architecture utilizes a plurality of character tables corresponding to the respective characters of the alphabet. A string is stored by storing the code associated with the string in the character table corresponding to the extension character of the string at a character table location corresponding to the code of the string prefix. A search for the longest matching string is performed by determining if the character table location is empty corresponding to the code of the currently matched string in the character table associated with the currently matched string in the character table associated with the currently fetched character. If the location is not empty, it is storing the code of the string comprising the currently matched string extended by the currently fetched character. This string code is used as the next match with which to continue the search with the next fetched character. When the location is empty, the longest match has been determined to be the currently matched string. The stored strings are updated by storing the next available string code in the empty location.
