Patent CA-2267477-A1 (CA)
Title: Packaging memory image files
Inventor: BURKA PETER WIEBE
IPC: G06F9/445
Filed: 1999-03-30
Abstract: In typical Java and other interpreted programming language environments, the code is stored in ROM in a semi-processed state, .class files containing byte codes. When the device is turned on, a virtual machine resolves references and links the .class file in RAM to permit desired applications to be run. In the invention, the .class files are further pre-processed to select the data which will not change or require updating. This data is packaged into memory image files containing internal data pre-linking this data. The memory image files are stored in ROM and are accessible from ROM by the virtual machine at runtime. Only elements that will be updated, such as the objects themselves, must be instantiated in RAM at runtime. This reduces the amount of RAM needed to run the application. In an environment with memory constraints, the reduction in RAM  requirements permits more RAM to be made available for application use.

Title: Epoxy-polysiloxane polymer composition
Inventor: ROJAS J LUIS
IPC: C08G77/38
Filed: 1997-05-06
Abstract: Epoxy-polysiloxane polymer compositions of this invention are prepared by combining a resin component with a hardener component. The resin component comprises a non-aromatic epoxy rein ingredient and a polysiloxyne ingredient. The hardener component comprises an amine and optionally an organotin catalyst. The composition can also include aggregates, pigments, and other additives depending on the particular end use. The composition is prepared using a sufficient amount of water to promote hydrolysis of the polysiloxane and the polycondensation of the silanols produced by such hydrolysis. In its cured form, the epoxy-polysiloxane composition exists as a uniformly dispersed arrangement of linear epoxy chain fragments that are cross-linked with a continuous polysiloxane polymer chain, thereby forming a non-interpenetrating polymer network chemical structure that has substantial advantages over conventional epoxy systems. Protective coatings formed from such compositions exhibit excellent weatherability in sunlight, and superior chemical and corrosion resistance after curing.

Title: Launderable, leak-proof, breathable fabric
Inventor: FILTEAU MARTIN
IPC: A41D31/02
Filed: 1999-11-10
Abstract: A launderable and reusable, leak-proof, breathable fabric and, more specifically, a composite fabric comprised of a liquid absorptive layer and a liquid impervious but vapour permeable layer. Such fabric is useful in drawing fluids, such as bodily fluids, away from a source, such as the body, and retaining them within the absorptive layer whi le evaporation thereof takes place though the vapour permeable layer. This material consist s of two juxtaposed layers. The inner layer has the characteristic of being liquid permeable so as to allow the body fluids to flow into it and be absorbed. The outer layer has t he characteristic of being liquid impermeable but air or vapour permeable, so that the liquid absorbed in the inner layer does not strike through the outer layer. Because the body fluids  can flow into the inner layer, the wearer does not experience a clammy feeling from the materi al next to the skin. The breathability of the outer layer also reduces wet feeling and will  in fact allow some evaporation of liquid collected in the inner layer. The material provid es the functions of absorbing or drawing minor quantities of bodily fluids away from the wear er yet is sufficiently thin and comfortable to be inconspicuous. In addition, the resulting fabric material is capable of being laundered, is stain resistant, and substantiall y retains its other properties after numerous cycles of use and washing. In general, the materia l comprises an absorbent acetate/nylon fabric to which is laminated or adhered a liquid imperviousness but vapour permeable microporous polyurethane film, to result in an substantiall y integral fabric material from which articles can be manufactured which can take advantage of  the material's absorbent, launderable/reusable, leak-proof and breathable nature .
