Patent CA-2377399-A1 (CA)
Inventor: CARSON JOHN KIT
IPC: B32B7/02

Abstract: La présente invention concerne un substrat fibreux (2) absorbant les liquides, ce substrat renfermant une pluralité d'alvéoles discontinues dans lesquelles est placé un second matériau. Ce second matériau est choisi parmi une large gamme de solides organiques ou inorganiques qui permettent de renforcer ledit substrat, empêchant du même coup tout instrument coupant de traverser la nouvelle structure composite ainsi obtenue. Ces matériaux de renforcement (1) sont placés de manière discontinue sous une forme alvéolaire à l'intérieur du substrat fibreux (2), ce qui ménage un passage pour les liquides destinés à être absorbés par ce substrat fibreux (2). Ces matériaux de renforcement (1), qui assurent une résistance à la pénétration d'instruments à arête vive, confèrent par ailleurs une grande souplesse au substrat, n'étant pas disposés de manière continue. Leur disposition ne forme de préférence aucune zone linéaire susceptible de tracer une ligne continue de pénétration pour des arêtes vives, et idéalement, cette disposition présente des formes entremêlées qui limitent la longueur de ces zones linéaires. Cette disposition alvéolaire de renforcement peut en outre être gaufrée au-dessus du substrat fibreux ou être sensiblement coplanaire par rapport à ce dernier. Ce substrat composite peut également être solidifié à l'aide d'une couche imperméable aux liquides (3), qui peut soit se présenter sous la forme d'une couche séparée fixée à la surface inférieure, soit être appliquée comme un revêtement. Enfin, cette couche imperméable aux liquides (3) peut être choisie avec soin en fonction de son coefficient de frottement élevée, qui lui permet de former une surface antidérapante.

Title: Food container with interchangeable lid-base seal design
Inventor: VAN HANDEL GERALD J
IPC: B65D41/18
Filed: 2002-05-22
Abstract: There is provided a container having both male and female sealing regions disposed about its periphery in a pattern making it possible to seal a container with another container having substantially identical sealing regions. The male sealing regions used in the practice of the present invention may take the form of a U-shaped ridge which is undercut along at least one leg of the U. Typically, a container will be thermoformed from lightweight thermoplastic material giving the U-shaped ridge considerable flexibility. The female sealing regions used in the practice of the invention may take the form of an undercut channel adapted to receive and match the undercut U-shaped ridges found in the male portion of the container wherein the walls and base of the channel are sufficiently flexible that the undercut portions of the U-shaped ridge are urged into engagement with the undercut portions of the channel and the crest of the ridge is urged into the channel. Preferably, both a medial portion of the crest of the U-shaped ridge and a mating medial portion of the bottom of the corresponding channel are substantially mating so that as the undercut portions of the channel and the undercut portions of the U-shaped ridge are urged into engagement, substantial surface to surface contact between the mating portions of the crest of the U-shaped ridge and the bottom of the channel will form an additional seal. In one particularly preferred mode of practicing the invention an enclosed container having identical top and bottom portions is provided with circumferential interlocks about the portions of the rim transitioning between male and female portions.

Title: Phase to sine amplitude conversion system and method
Inventor: AL-KHALILI DHAMIN
IPC: H04B1/713
Filed: 2002-08-14
Abstract: A phase-to-sinusoid-amplitude conversion system and method for use in, for example, direct digital frequency synthesizer applications. The system and method convert phase data to signal amplitude data using an approximation of the first quadrant of a sine function using a plurality of linear line segments of preferably equal length. Each segment is defined with a lower horizontal-axis bound; a lower vertical-axis bound; and a slope represented as a sum of a plurality of slope elements. Based on the approximation and for a given phase angle a set of values are evaluated, for each linear line segment, representing a product of (i) a horizontal displacement representing a difference between the prescribed phase angle and the lower horizontal-axis bound x 1 of a selected linear line segment where, for example, x 1<X<x 1+ 1 and (ii) each one of the slope elements of the selected linear line segment. The approximation of the sinusoidal amplitude is then obtained by adding one of the sets of values determined above with the lower vertical-axis bound of the selected linear line segment. With appropriate selection of the number of line segments (e.g., integer power of two) and slopes elements (e.g., expressed as a sum of desired powers of two), the operations are computationally efficient and improve spectral purity and reduces implementation costs and power consumption of resulting circuitry.

Abstract: A public policy auction system (10) for providing a monetary incentive for t he adaption of efficient public policies. The system generally comprises a seri es of hierarchical negotiations and auctions for the proprietary right to recei ve a portion of the savings generated from the efficiency of a given public policy. The method begins with a registration phase during which information  is collected on the proponents of new public policies, and shares are established for a portion of the approximate distribution of savings gained by implementation of the efficient public policy. The shares are auctioned to potential constituents during an active auction. The active auction method includes penalties to force constituents to combine and pool their bids, thereby encouraging cooperation and minimizing frivolous bids.The active auction is complemented by an innovator auction in which a predetermined number of policy innovators (11) are selected to become competing bidders, a nd a predetermined interval of time is established before additional innovators  (11) may participate. The entire system is administered over the internet (3 0) by a series of software modules:
