Title: Method for making secure an electronic entity with encrypted access
Inventor: GIRAUD CHRISTOPHE
IPC: H04L9/10
Filed: 2003-04-02
Granted: 2012-10-30
Abstract: The invention concerns a method for protecting an electronic entity with encrypted access, against DFA (Differential Fault Analysis) attacks which consists in: storing the result of a selected step (R¿m?, K¿n?) of an iterative process forming part of the cryptographic algorithm and in performing once more at least part of the steps of said iterative process up to a new computation of a result corresponding to the one which has been stored, comparing the two results and denying distribution of an encrypted message (MC) if they are different.

Abstract: A network communication card is provided for facilitating ultra high frequency (UHF) radio communication between a terminal and a base station, the network communication card being in communication with an antenna and comprising a double-sided multilayer printed circuit board (PCB). The PCB comprises a digital interface, a receiver and a transmitter. The digital interface provides communication between the PCB and the terminal. The receiver receives incoming radio signals from the base station and processes the received signals for communication to the terminal via the digital interface. The transmitter transmits outgoing radio signals from the terminal via the digital interface to the base station and includes the following components. A digital synthesizer provides a highly accurate modulated carrier signal. An upconversion circuit increases the frequency of the carrier signal. A filter filters spurious content from the carrier signal. A phase locked loop (PLL) comprising a synthesizer and a voltage controlled oscillator (VCO) generates a transmission signal from the filtered carrier signal. A transmission circuit transmits the transmission signal via the antenna.

Abstract: Un Appareil à base rotative destiné à être utilisé avec un boîtier enrouleur. La base comprend une partie supérieure et une partie inférieure. Un roulement est situé entre les parties supérieure et inférieure et permet aux parties de pivoter l'une par rapport à l'autre. Le roulement peut comporter des boulets montés dans des cavités dans la partie de base inférieure qui roulent sur une voie dans la portion de base supérieure. Des clips sont prévus sur la partie de base supérieure pour y fixer le boîtier enrouleur. Cette disposition permet à l'utilisateur de retirer le tuyau de l'enrouleur dans n'importe quelle direction sans risquer de faire basculer le boîtier enrouleur. Le boîtier enrouleur pivotera dans la direction dans laquelle le tuyau est retiré. Il permet également au boîtier enrouleur de pivoter dans la direction dans laquelle le tuyau est enroulé sur l'enrouleur. Cela empêche le tuyau d'être enroulé de façon inégale sur l'enrouleur, par exemple en s'empilant sur un côté de l'enrouleur.

Title: Item with an optical effect
Inventor: LUETHI MARKUS
IPC: G02B27/60
Filed: 2006-09-18
Granted: 2013-01-08
Abstract: An item with a surface area creating an optical effect to increase protection against forgery is such that the surface area with the optical effect exhibits at least two images (12, 14) spaced a distance (d) apart. A first image (12) is situated on the surface (11) of a layer of material (10) and the second image (14) is virtual and, by holographic coding, appears to lie a distance (d) from the first image (12). By changing the angle of viewing, the optical perception of the whole image formed by the overlapping of the images (12, 14) changes, whereby the images (12, 14) are matched with respect to each other such that they demonstrate Moiré interference effects. A preferred application for the item is packaging, packaging material, packaging aids, bonds or entry tickets with forgery-proof and / or optically demanding surface area.

Abstract: A singulating disc (20), carried by a housing, has a plurality of openings (28) around its periphery. The disc (20) rotates vertically through a pickup chamber of a hopper (12) carried by the housing. A vacuum is pulled through the openings (28) by a pump which is connected to the disc (20). Items are placed in the hopper (12) and, via gravity, fall to the bottom of the hopper (12) where they contact the periphery of the rotating disc (20). The vacuum at the openings attaches an item and holds it while the disc (20) rotates. At the top of the disc's rotation, a diverter (26) directs the item into a path depending on the results of a fragment detection and/or counting mechanism.  Items that are allowed to pass by the diverter (26) are scraped off the disc into another path by a scraper (15). Negative pressure is used to singulate and count a multitude of sizes and shapes of items with no calibration.  Retractable paddles (62), a vacuum management system, and RFID tags may be incorporated. The paddles (62) aid in the pickup and agitation of the items while the vacuum management system conserves the vacuum capacity necessary to pickup and singulate items. The RFID tags may contain information such as the number of items left in the hopper, a par level for that item, an expiration date, among others. Because of the rules governing abstracts, this abstract should not be used to construe the claims.
