Patent CA-2396109-A1 (CA)
Inventor: HASHA RICHARD
IPC: G06F9/44
Filed: 2000-02-03
Abstract: A method and system for tracking access by clients to a server object of a server class. The client tracking system provides a derived client tracking server class that includes an overriding implementation of a query function of the server class. The overriding implementation instantiates a phantom server object and returns a pointer to the instantiated phantom server object. The phantom server object has functions that correspond to and override the functions of the server class. These overriding functions perfo rmed custom processing on a client-by-client basis and forward their invocation to be corresponding functions of the server object. When a client invokes the query function of the client tracking server object, a pointer to a phantom server object is returned. From then on, when that client invokes a function of the phantom server object, custom processing can be performed for that client.

Title: Compositions with enhanced oral bioavailability
Inventor: DUNCAN RUTH
IPC: A61K47/48
Filed: 2001-01-16
Abstract: The present invention describes the use of polysaccharides, surfactants, and  dendrimers as bioavailability enhancers for oral pharmaceutical compositions . These substances exhert an inhibitory action of the gastrointestinal pump efflux proteins, such as the P-glycoprotein and the MDR protein, responsible  for poor drug bioavailability and multidrug resistance. The formulations herein described comprise a medicinally active substance in association with  said polysaccharides, surfactants, and dendrimers. They are well tolerated, are not absorbed by the gastrointestinal tract, and increase the bioavailability and the activity of orally administered medicaments, like e. g. antineoplastic, antiviral, antibiotic, or antidepressant medicaments.</SDOAB >

Abstract: The present invention relates to the provision of materials intended for use in an oxidative medium at high temperatures, including the manufacture of high-temperature electric heaters, parts, sensors and tools operating at temperatures of up to 1900°C and higher. On the basis of silicides - solid solutions (Mo, W)5Si3 and (Mo, W)Si2 as well as Novotny phase (Mo,W)5Si3C containing molybdenum and tungsten, a heat-resistant material is proposed, which makes it possible to produce parts fully made therefrom and a broad range of other heat-resistant materials for the provision of protective coatings and soldered joints:  "REFSIC" composite materials, carbon, silicon carbide materials, refractory metals and their alloys. Extensive property-varying potentialities by controlling the phase composition, a large diversity of the structural features of single-layered and multilayered protective coatings make it possible to control the heat-resistance, resistance to thermal shocks and resistance to combined thermal deformations of the coating as such and of parts produced by soldering other high-temperature materials with the help of the proposed heat-resistant material. The proposed electric heaters can have working parts and current lead-in wires made from the above-mentioned high-temperature materials, having soldered joints and protective coatings prom the proposed material in different combinations of materials and heater designs.

Title: An apparatus and method for performing selective photocoagulation
Inventor: LIN CHARLES P
IPC: A61B17/00
Filed: 2001-06-01
Abstract: Selective photocoagulation of particular cells, tissue or portion of tissue can be aided by monitoring microcavitation within the material exposed to electromagnetic radiation (12). The information gained by the detection of microcavitation events can be used to modulate the intensity of the radiation (12) to prevent significant thermal energy transmission and mechanical damage to cells, tissues or portions of tissues which are not directly exposed, but prone to thermal damage by such energy transmission. Detection of microcavitation also serves as a valuable therapeutic endpoint. The methods of the invention are applicable to laser eye surgery, since the target cells of several therapeutic photocoagulation methods, the retinal pigment epithelial (RPE) cells are proximate to photoreceptor cells. The inventive methods can help prevent the formation of blind spots that can be associated with laser eye surgery. Other fields of laser surgery can also be readily adapted to the methods described herein.
