Title: Fiber optic pressure sensitive optical switch and apparatus incorporating same
Inventor: HUMPHREY ASHLEY C
IPC: G01F23/16
Filed: 1999-03-17
Abstract: An optical switch operatively sensitive to a fluid pressure differential includes a housing having an open end, a fiber optic input line, a fiber optic output line, and a fluid-proof diaphragm sealingly engaged with the housing. The diaphragm is formed from a thin elastic material resiliently stretchable between first and second switching states and supports an optical barrier within the housing for blocking the propagation of an optical signal between the fiber optic lines when the diaphragm is in one switching state and for permitting the propagation of the signal between the fiber optic lines when the diaphragm is in the other one of the switching states. For a given housing and a given diaphragm, different optical barriers may be employed to achieve different switching thresholds. As well differing optical barriers may be used to make the switch either a normally "on" switch or a normally "off" switch. Apparatus for monitoring the level of a liquid may include a plurality of such switches.

Inventor: DELMAIN GREGORY J
IPC: A61F2/82
Filed: 1997-12-12
Abstract: La présente invention concerne un procédé permettant d'améliorer la biocompatibilité de dispositifs, en particulier de dispositifs médicaux qui sont placés, de façon invasive, dans le corps d'un patient. L'invention concerne également un tel dispositif médical amélioré. La présente invention permet en particulier de réduire la thrombogénicité de matériaux du type polyuréthanne en contact avec le sang d'un patient vivant. Le procédé consiste à se munir du dispositif médical biocompatible recouvert de composants polymères en polyuréthanne, à exposer les composants en polyuréthanne de ce dispositif médical à des solvants polaires destinés à de tels composants polymères, tandis que ces solvants polaires sont en phase vapeur, et à faire en sorte que ladite exposition aux solvants polaires en phase vapeur continue pendant un temps suffisant pour réduire au moins certaines parties irrégulières ou pointues de la surface du composant polymère. L'invention concerne un procédé permettant d'améliorer un dispositif médical pourvu au moins d'un composant polymère, ce procédé consistant à produire une phase vapeur comprenant un solvant destiné auxdits composants polymères et à exposer celui-ci à cette phase vapeur. Selon le procédé, on prend un composant en polyuréthanne dont la surface présente un certain relief (par exemple rugosité, rainures, ondulations, arêtes vives, écarts par rapport à la planéité, etc.), et on expose ce composant en polyuréthanne à ladite phase vapeur pour augmenter sa planéité. Cette opération se fait sans réaction chimique avec le composant polymère et, grâce à la régulation de la quantité de solvant pouvant entrer en contact avec le polymère, le risque d'endommagement du composant polymère est réduit. En particulier, le traitement par phase vapeur permet de réduire la taille de marques d'extrusion se trouvant sur la surface extérieure du polyuréthanne avec un risque minimum d'endommagement de la structure du polyuréthanne, cela même lorsque le polyuréthanne se présente sous la forme de parois minces (par exemple d'une épaisseur inférieure à 0,0762 mm).

Title: Wireless communications system and method of operation for reducing fraud
Inventor: MORGAN JOSEPH LAMANCE
IPC: H04W12/12
Filed: 1998-01-30
Abstract: The wireless communications system includes a home carrier and HLR memory means, associated with the home carrier, for storing a number of Home Locator Records defining the level of service to be provided to the individual subscribers of the home carrier. The Home Locator Record is at least initially configured to prohibit call termination of the respective subscriber outside of the predetermined service area of the home carrier. However, the wireless communications system also includes reconfiguring means for at least temporarily reconfiguring the Home Locator Record of a respective subscriber in response to a request for communications service involving the subscriber who has roamed outside of the predetermined service area of the home carrier if the subscriber has prepaid for the requested services. Once reconfigured, the wireless communications system can provide the Home Locator Record of the respective subscriber to a serving carried via IS-41 (Rev. A) messaging. The reconfigured Home Locator Record serves as the roaming subscriber's Visitor Locator Record which, in turn, authorizes the requestd wireless communications service. Once the requested service has been ended, either upon completion of the call or exhaustion of the prepaid services, the reconfiguring means resets the Home Locator Record of the respective subscriber such that the Home Locator Record again prohibits call termination with the subscriber outside of the service area of the home carrier in order to further protect the wirelsss communications system from fraud.
Patent CA-2285166-A1 (CA)
Title: Secure method for generating cryptographic function outputs
Inventor: BERENZWEIG ADAM L
IPC: G09C1/00
Filed: 1999-10-07
Abstract: Data that indicates the use of a pseudorandom function output is used to modify at least one value used to produce the pseudorandom function output. In one embodiment, the output control signals provided to a User Identity Module (UIM) device are used as inputs to a pseudorandom function processor. As a result, the output provided by the processor differs based on whether the output from the processor is going to be stored in a key storage area or exported for use outside the UIM. This technique solves the problem of the prior art by insuring that values that are exported or presented at the output of UIM module, are different than the values that are stored within the UIM module as key values. As a result, an attacker would receive values at the output of the UIM that are different than the values stored in the key storage unit and therefore, would not be able to impersonate the mobile terminal or compromise the privacy of the terminal's communications.

Title: Proof that contraction of the calf cannot increase pressure on the pedal and mechanisms for exploiting this basic discovery
Inventor: JACQUES ANDRE
IPC: B62M1/36
Filed: 1999-10-25
Abstract: In order to understand the invention, it is necessary to BEGIN by understanding IN DEPTH the following DISCOVERY which relates to the calf during pedaling;  the entire world is misled by two OPTICAL ILLUSIONS (figs. 21 and 22 symbolize a lower member pressing down upon a pedal, 6 is the thigh, 11 the leg, A+B the foot and 1 is the ankle). The first ILLUSION (fig 21) is to believe that the calf (M) INCREASES the pressure on the pedal. The second ILLUSION (fig 22) is to FAIL to  see that the force M is CANCELLED OUT by the force M'. The total amount of pressure on the pedal is derived from the THIGH EXCLUSIVELY, whereby the contraction of the CALF is a loss of energy. The aim of the invention is to REPLACE the pedal by a mechanism which AVOIDS THE USE OF THE CALF, thereby enabling performance to be MULTIPLIED BY TWO WITHOUT incurring A LOSS OF POWER!

Title: Rotational molding
Inventor: ZWART GERRIT
IPC: B29C41/04
Filed: 2000-01-19
Abstract: The present invention provides a new and improved method of using a volatile liquid color system to prepare colorant-coated polymeric resin powders for use in rotational molding. The method according to the present invention includes simultaneously feeding polymeric resin pellets or granules and a volatile liquid color system into a grinding mill to produce a colorant-coated polymeric resin powder for use in rotational molding. During grinding, the volatile liquid color system coats the surface of the freshly ground polymeric resin powder and dries, leaving no residues that will volatilize during rotational molding or exude from the surface of rotationally molded parts during molding. The method of the present invention eliminates the need for additional processing steps after resin grinding, such as distributive mixing and drying. Rotational molded articles produced according to the present invention exhibit excellent color uniformity.
