Patent CA-2322404-A1 (CA)
Title: Automatic resynchronization of crypto-sync information
Inventor: SOLER MILTON A
IPC: H04L9/12
Filed: 2000-10-05
Abstract: An apparatus and method for transmitting and receiving cryptographic information which provide a mechanism for resynchronization between a transmitter and receiver of the cryptographic information. A cryptographic synchronization counter at the transmitter generates a transmitter signature tag. A corresponding cryptographic synchronization counter at the receiver generates a receiver signature tag.  Information is ciphered and the transmitter signature tag is appended to the ciphered information. The ciphered information is received. The transmitter signature tag is compared to the receiver signature tag and the cipher text is decipher into plain text if the tags are equal. If the tags are not equal, the receiver crypto-sync counter is incremented and a new receiver signature tag is calculated to determine if the receiver is resynchronized (i.e., tags are equal) to the transmitter. If after a certain number of increments, resynchronization does not occur, a resynchronization procedure is initiated.

Patent CA-2327785-A1 (CA)
Title: Method and apparatus for fine frequency synchronization in multi-carrier demodulation systems
Inventor: BUCHHOLZ STEPHAN
IPC: H04L27/26
Filed: 1998-04-14
Abstract: A method and an apparatus relate to a fine frequency syn-chronization compensating for a carrier frequency deviation from an oscillator frequency in a multi-carrier demodulation system of the type capable of carrying out a differential phase decoding of multi-carrier modulated signals, the sig-nals comprising a plurality of symbols, each symbol being defined by phase differences between simultaneous carriers having different frequencies. A phase difference between phases of the same carrier in different symbols is deter-mined. Thereafter, a frequency offset is determined by eliminating phase shift uncertainties related to the trans-mitted information from the phase difference making use of a M-PSK decision device. Finally, a feedback correction of the carrier frequency deviation is performed based on the deter-mined frequency offset. Alternatively, an averaged frequency offset can be determined by averaging determined frequency offsets of a plurality of carriers. Then, the feedback correction of the frequency deviation is performed based on the averaged frequency offset.

Title: Alarm cable
Inventor: FOSEIDE KNUT
IPC: G08B13/14
Filed: 1999-04-06
Abstract: Alarm cable II, wherein a siren is triggered when there is a loss of mains voltage, characterised in that a switch function (SW) in the connector (3) also registers that the alarm is not disconnected from the appliance that is to be secured. In the connector (3) there is also a fastening device (14, 15) which is connected to a circuit (8) which registers whether the fastener is released, and then triggers the alarm. In the plug (2) to the mains supply there is a microswitch (SW) which makes it possible to distinguish between attempted theft and regular power failure. A varistor and a gas discharger connected in parallel relation across the mains phase protect against lightening or surge voltage. There may be input terminals for telephone lines which allow pager or mobile phone signalling.

Patent CA-2342618-A1 (CA)
Inventor: MURRAY JAMES R
IPC: H04Q3/00
Filed: 1999-09-07
Abstract: L'invention concerne un système et un procédé utiles dans un réseau de radiotélécommunications pour fournir de manière interactive à un appelant (11) un choix d'options de traitement d'appel quand une station mobile (SM) (13) est occupée ou inactive. Quand un appel (31) est reçu pour la SM appelée dans le réseau, un registre des positions des stations de rattachement (HLR) (15) détermine l'état de la SM (13) appelée (c.-à-d. si celle-ci est disponible, inactive ou occupée). Si la SM appelée est inactive ou occupée, l'état est envoyé à un point de commande de services (PCS) (16) qui produit plusieurs options de traitement d'appel en fonction de l'état déterminé de la SM appelée. Les options de traitement d'appel sont présentées à l'appelant (11) dans un procédé d'invite interactif pouvant prendre la forme d'un affichage de menu ou d'une invite vocale. L'appelant sélectionne ensuite une option de traitement d'appel qui est envoyée au PCS (16). L'appelant peut faire en sorte que le réseau établisse automatiquement un appel avec la SM appelée si celle-ci est réactivée au cours d'une durée spécifiée. Le PCS détermine les actions (41) nécessaires pour exécuter l'option de traitement d'appel sélectionnée, et exécute les actions déterminées. L'établissement (50) d'un appel entre l'appelant et la SM appelée se déclenche quand la SM appelée se rattache (45) au réseau. Si la durée s'est écoulée sans que la SM ne se rattache au réseau, l'appelant en est informé et peut prolonger cette durée ou enregistrer un message vocal.
