Title: Method and apparatus for automatic database encryption
Inventor: WESSMAN RICHARD
IPC: G06F17/30
Filed: 2001-10-05
Abstract: One embodiment of the present invention provides a system for managing encryption within a database system that is managed by a database administrator, and wherein a user administrator not otherwise associated with the database system, manages users of the database system. This system performs encryption automatically and transparently to a user of the database system. The system operates by receiving a request to store data in a column of the database system. If a user has designated the column as an encrypted column, the system automatically encrypts the data using an encryption function. This encryption function uses a key stored in a keyfile managed by the security administrator. After encrypting the data, the system stores the data in the database system using a storage function of the database system.

Title: Base pivotante pour chaise
Inventor: JACQUES ANDRE
IPC: A47C1/032
Filed: 2003-04-24
Abstract: Désavantages d'une chaise conventionnelle (de table etc): la pression p ar centimètre carré sur le plancher est élevée, on a tendance à tramer la chais e sur le plancher pour la déplacer en se levant partiellement (ce qui est bruyant); l e plancher devient endommagé. La base pivotante élimine ces désavantages et apporte des avantages supplémentaires. Les pattes de la chaise (1) s'insèrent dans l'extrémité des 4 pièces (9). Deux bases circulairse (3 et 4) sont reliées ensemble par un joi nt de rotation situé au centre des bases. La base du haut (3) TOURNE sur la du base du bas (4) (qui ne tourne pas) grâce à des billes de roulement (5) disposées en cercle entre le s deux bases (sur la circonférence). Cela permets à la personne assise de se tourner vers une autre personne sans risque d'endommager le plancher (2) et sans aucun bruit. La particularité de la base du bas (4) est qu'elle comporte 3 roues (6) disposées en triangle so us la base. Ces roues sont équippées de ressort à compression (7). Quand personne n'est assi s, il est facile de déplacer la chaise (sans bruit) grâce aux roues qui sont sorties. Quand l a personne s'assoie, les roues entrent dans la base du bas. La base du bas repose sur l e plancher, avec une pression par centimètre carré très faible car la surface de la base circulaire esttrès grande, contrairement à 4 pattes de chaise. Donc, aucun dommage au plancher et aucun bruit.

Title: One-step synthesis of amphiphilic diblock copolymers from bacterial poly(¬r|-3-hydroxybutyric acid)
Inventor: RAVANELLE FRANCOIS
IPC: C08G63/46
Filed: 2003-05-29
Abstract: Because hydrophobic drugs are difficult to release by diffusion through matrices of hydrophilic polysaccharides, synthesis of compatibilizers was undertaken.  Using a natural hydrophobic polyester: poly([R]-3-hydroxybutyric acid), PHB, possessing a high enthalpy of crystallization, a self assembly amphiphilic system was created.     Diblock copolymers of monomethoxy poly(ethylene glycol), mPEG and PHB were synthesized in a one-step, solvent-free, transesterification reaction. The resulting diblock copolymers were used to form colloidal suspensions of nanoparticles that are potential drug carriers and compatibilizers. Catalyzed transesterification in the melt is used to produce diblock copolymers of poly([R]-3-hydroxybutyric acid), PHB, and monomethoxy polyethylene glycol), mPEG, in a one-step process. Bacterial PHB  of high molecular weight is depolymerized by two consecutive and simultaneous reactions: pyrolysis and transesterification. The formation of diblocks is accomplished by the nucleophilic attack from the hydroxyl end-group of the mPEG catalyzed by bis-(2-ethylhexanoate) tin. The resulting diblock copolymers are amphiphilic and self assemble into sterically stabilized colloidal suspensions of PHB crystalline lamellae.

IPC: A61B17/70
Filed: 2002-04-04
Abstract: An arrangement and method of use for supporting a plurality of vertebrae in a cervical column in predetermined spatial relation and for facilitating a spinal fusion procedure. A plurality of templates (12, 14) couple to respectively associated vertebrae at anterior lateral surfaces thereof. Such coupling is effected with fasterners, such as bone screws (19). The template s are slidingly coupled to each other by a coupler assembly (22) whereby they are displaceable along a path over a limited distance that is substantially parallel to the longitudinal axis of the cervical column. The sliding displacement between the templates is limited by a pair of protruding tongue s (27) that extend through elongated apertures (29). The elongated dimension o f the apertures determines the extent of sliding travel, which extent is established to accommodate subsidence of the bone fusion and to prevent separation of the sliding elements of the coupler assembly. The coupler assembly is coupled to each template by engagement between posts (18) and po st holes (15). Additionally, locking plates and fasteners, such as threaded fasteners, are used to ensure the security of the engagement between the templates and the coupler assembly. Sequential replication of the arrangemen t enables three or more vertebrae to be supported in the determined spatial relation.

Abstract: The present invention relates to the process of selectively exposing matter to a specific wavelength of electromagnetic energy in sufficient flux density p er wavelength to cause or promote a desired effect. The process includes, but i s not limited to, destroying, disinfecting, denaturing, disinfesting, disrupting, or dehydration of one or more of the substances present. More specifically, present invention relates to subjecting matter, which may contain a mixture of substances, to electromagnetic energy, in concurrence with its spectral properties to exploit the spectral differences within the substance or within a mixture of substances. Energies are applied to cause wavelength-dependent reactions resulting from differential absorption; this additional applied energy manifests itself in changes, or quantum transition s, in the vibrational, rotational, magnetic, and electronic states of the molecules. Generally, the process utilizes wavelengths from about one light second to about ten electron volts, or wavelengths with energy levels less than that of ionization.
