Patent CA-2356734-A1 (CA)
Inventor: HUGHES JAMES P
IPC: G06F12/14
Filed: 2001-09-05
Abstract: Information that must remain secure is often stored on untrusted storage devices. To increase security, this information is encrypted by an encryption value prior to storing on the untrusted storage device. The encryption value itself is then encrypted. The encryption value is decrypted by correctly solving an access formula describing a function of groups. Each group includes a list of at least one consumer client. A requesting consumer client is granted access to the information if the requesting consumer client is a member of at least one group which correctly solves the access formula.

Title: Low frequency electromagnetic analysis of prestressed concrete tensioning strands
Inventor: MCINTYRE JOHN
IPC: G01N27/82
Filed: 2001-11-13
Abstract: Discloses apparatus and methods of operation of the apparatus for performing magnetic testing of pre-stressing elements in a pre-stressed concrete cylinder, such as a pipe or water reservoir. The apparatus includes magnetic flux production means disposed proximal to a surface of the cylinder under test and detector means disposed proximal to a surface of the cylinder in a plane in common with the magnetic flux production means that is orthogonal to an axis of the cylinder. The apparatus operates over a range of low frequency periodic signals, for example, between 20 and 300 hertz.      Output of the inspection apparatus includes analysis providing a multi-frequency plot showing the results of testing a cylinder using two or more frequencies. In accordance with another method of analysis, a single frequency is plotted along with a transformation plot, the transformation plot produced by transforming either the in-phase or quadrature components of the received signal in relation to the periodic driving signal by an angle alpha.

Title: Photonic band gap materials based on spiral posts in a lattice
Inventor: TOADER OVIDIU
IPC: G02B6/122
Filed: 2001-11-16
Abstract: The present invention relates to photonic band gap (PBG) materials and more specifically, it describes a new type of photonic crystal structure which exhibits a large and complete three-dimensional PBG. This PBG is highly robust to the effects of disorder. The photonic crystal has a tetragonal or hexagonal lattice symmetry and is comprised of a lattice of polygonal spiral posts of a high refractive index material in a low index background. The corresponding inverse structure comprises a lattice of low refractive index posts in a high refractive index background also has a very large PBG. These new photonic crystals exhibit very large (up to 23.6% when made of silicon and nearly 29% when made of germanium) complete 3D photonic band gaps. The posts exhibit a spiral profile and all the spiral posts wind in phase with each other. The identity of the winding phase from one post to the next makes the present invention amenable to micro-fabrication using the Glancing Angle Deposition (GLAD). The present invention provides a blueprint whereby the GLAD technique can be adapted to synthesize these new types of PBG materials. These materials have applications in lightwave technologies.

Title: Materials and processes for controlled release of thioamide moiety-containing therapeutic agents by linking to thiol-containing polymers
Inventor: STEIN STANLEY
IPC: A61K47/48
Filed: 2000-07-24
Abstract: This invention pertains to disulfide-linked conjugates of therapeutic agents  containing at least one thioamide group with polymer comprising at least one  thiol group, so as to provide a controlled release pharmaceutical compositio n for administration to animals for the prophylaxis or treatment of various conditions or diseases. The therapeutic agent conjugate may comprise an inactive or weakly active prodrug form which may be converted into the original therapeutic compound by the natural action of reducing agents in vivo. The composition may comprise a mixture of polymers each with a differe nt thioamide-containing agent attached, or a polymer conjugated with a mixture of thioamide-containing agents. Modified properties of the therapeutic compound  potentially provided by the polymer itself, as well as by other compounds al so appended to the polymer, include but are not limited to greater water solubility, longer in vivo half-life (due to larger size of the conjugate), slower release from a sustained-release depot (due to larger size of the conjugate), better oral bioavailability and tissue-specific targeting.</SDOA B>
