Abstract: A child-resistant compact or tablet case of one-piece molded plastic construction made up of a generally flat rectangular base and a cover top interconnected by an integral "living" hinge. A pair of mating lip flanges extend one each along the front edges of the base and top, i.e., the edges remote from the hinge. Each flange has an arcuate recess, and these recesses are mutually offset from each other laterally of the case when it is closed with the flanges lying against one another. By placing a thumb in one recess, and the tip of the forefinger in the other recess, a pry-open force may be applied to thus readily open the case. Since only one recess is visible when viewing the case from the top or the bottom, this manner of opening the case is not readily apparent to an infant or young child, but is very easy for an infirm or elderly adult to comprehend and use for opening the compact case merely by forger feel. In addition, the base has a pair of latch spring fingers disposed one on each of the laterally opposed sides near the front edge of the base and that protrude upwardly from the base bottom wall in cantilever fashion. The top has a cooperating pair of pockets that receive the free latch-tang ends of the spring fingers to render there exterior-accessible in the closed condition of the case. The outer edges of these pockets form the strike portion of the latch system.  To open the case, squeeze pressure must be applied with one hand simultaneously to both of the spring finger tang ends to move them to unlatched condition, and then to hold them in this condition while, also simultaneously, with the other hand pry-open pressure is applied to the two front lip flanges at the aforementioned offset recesses. This two-handed operation further resists opening by a child because of its complex dual-hand-manipulative coordination requirement.

Abstract: Procédé et dispositif améliorés permettant de protéger les logiques de clés publiques, sur la base de l'exponentiation modulaire (RSA et Diffie-Hellman notamment), contre les techniques crypto-analytiques indirectes, telles que les attaques basées sur la séquence des opérations et les fautes. Typiquement, les procédés connus permettant d'implémenter des logiques théoriques de nombres qui résistent à ces attaques doublent le temps d'exécution, tandis que les nouveaux procédés et dispositifs décrits dans ce brevet n'ajoutent qu'une surcharge système négligeable. Cette amélioration est particulièrement significative pour les cartes à puce et les implémentations reposant sur un logiciel, dans lesquelles l'opération d'exponentation modulaire est assez lente et où le doublement de leur durée risque d'être une solution inacceptable.

Abstract: A system and a method for coating two sides of a laminate material is disclosed in which one side of the laminate material is coated with one substance and the second side is coated with a similar or different substance. Reverse roll coating may be used to coat the two surfaces of the sheet of laminate material. The method described is particularly suited for applying a substance providing balancing characteristics desirable in the end product to one side of the laminate material and applying a substance providing other characteristics desirable in the end product to the other side of the laminate material. For example, a balancing substance may be applied on one side of a kraft paper sheet and a substance providing structural bonding applied to the other side, thereby eliminating the need to use a discrete balancing sheet in a laminate. The kraft sheet thus coated may be used to form a laminate panel that may be applied on an exterior wall, an interior wall, siding, a roof top, a facade boarding, a counter top, a table top or a work top.

Abstract: A technique for spreading information signals in a spread spectrum communication system to provide increased signal acquisition speed. A first PN spreading code or code set is used to spread information signals along with a second PN spreading code sequence or function. The second PN code is synchronized with the first PN spreading code, but has a larger code period so that each code chip of the second PN code extends over the entire period of the first PN code. The longer period spreading code forms an outer code which helps provide unambiguous beam identification and easily acquired frame timing in the presence of dynamically changing signal path delay, improving signal acquisition.

Title: Reflective laser collimator
Inventor: COLE IRA E III
IPC: B23K26/06
Filed: 2000-07-11
Granted: 2003-03-18
Abstract: A reflective collimator for a laser, such as for use in a cutting or welding machine tool. The collimator requires no more than three minors, and can be configured with only two. The relative positions of a convex/concave mirror pair are adjusted to adjust the divergence of the output collimated beam. Adjustment is accomplished by translating two of the mirrors in linear paths along respective beam paths established in the collimator. A linkage interconnects the two translatable mirrors and includes a coupling which incorporates the triangular geometry of the beam path established by the mirrors, so that the translatable mirrors are linked to maintain alignment throughout the range of collimator adjustment. When one of the translatable mirrors is adjusted the linkage causes the second to track the first while maintaining precise alignment in the collimator.

Title: Generalized modal space drive control system for a vibrating tube process parameter sensor
Inventor: CUNNINGHAM TIMOTHY J
IPC: G01N9/00
Filed: 1999-01-13
Granted: 2004-03-23
Abstract: A drive system is taught for controlling the modal content of drive signals used to excite drives on a vibrating conduit, such as in a Coriolis mass flowmeter or a vibrating tube densimeter. Motion signals are obtained from spatially distinct feedback sensors. A modal response signal corresponds to one of the vibration modes at which the vibrating conduit is excited. Modal response signals are input to a drive channel, each having a separate processing channel. Within each channel, the respective modal response signal is compared to a desired modal response setpoint. The resulting mode error signal is amplified to produce a modal excitation signal for each mode. The modal excitation signal, representing the modal excitation applied, is transformed from the modal domain back to the physical domain and mapped to physical locations of the drives. The resulting drive signals are applied to the drives to excite the conduit.

Granted: 2005-09-20
Abstract: Unequal channel error protection is provided for a bit stream, e.g., a progressive source coded bit stream, by puncturing of a channel code. The channel code has a specified rate associated with a corresponding level of error protection, and is used to code a first portion of the bit stream. The channel code is subsequently punctured for at least a second portion of the bit stream so as to provide a rate higher than that of the designated rate. Commencement of the puncturing is deliberately delayed by an amount determined based at least in part on a memory of the channel code. Advantageously, the delay prevents propagation of errors in a channel decoder used to decode the channel coded bit stream. The progressive bit stream may be a progressive source coded video or audio bit stream, any other type of progressive information bit stream, or a partitioned source coded bit stream.

Abstract: A telecommunications system, apparatus and method is disclosed for optimizing the use of paging channels within the network by dividing location areas (LAs) into sub-location areas (sub-LAs) and providing a more efficient and flexible method of paging mobile subscribers. The amount of usage of the paging channels and the number of location updates performed by a mobile subscriber can be monitored by the network to determine either statistical data or a subscriber category, e.g., heavy-user or light-user, which can be stored within the Subscriber Identity Module (SIM) card within the mobile station (MS). The sub-LA information along with the LA information for the cell that the mobile terminal is in is broadcast and monitored by the SIM card within the MS, which can then perform location updates based upon the category or data. The Mobile Switching Center/Visitor Location Register can also use the data or category for paging purposes, e.g., either page within the entire LA or within only the sub-LA, for more focused paging.
