Title: Oscillator with increased reliability start up
Inventor: LOGAN SHAWN MICHAEL
IPC: H03L3/00
Filed: 1995-09-28
Granted: 2000-01-25
Abstract: Oscillation is easily and reliably initiated in an oscillator by increasing the gain of the circuit at startup time. For example, the gain of an oscillator circuit may be increased at startup by reducing the value of a user controlled impedance until oscillation commences. Alternatively, or in combination, the input impedance of an amplifier used in the oscillator may be reduced at startup to facilitate the initiation of oscillation.
Patent CA-2165874-C (CA)
Inventor: MUELLER KURT HUGO
IPC: H04L9/08
Filed: 1995-12-21
Granted: 1999-03-23
Abstract: A symmetric procedure avoids the problems with prior art systems using modifiers with master keys and generates a secure session key from a secret master key and an additional pair of randomly selected signals. The secret master key is known to both parties: one at station A and one at station B. One randomly selected signal of the pair is generated by the party at station A while the other signal in the pair is generated by the party at station B. In one embodiment, a random number signal sent by each one of the parties to the other is encrypted before transmission and decrypted upon reception. Both encryption (at one station) and decryption (at the other station) employ symmetric key cryptographic systems which use the secret master key. The session key is then formed by a commutative combination of both random number signals.

De préférence, une amélioration est apportée à une telle enrouleuse, de sorte que l'espace (DR) délimité par les deux cylindres porteurs (TW1 et TW2) et l'enroulement (R) en cours de production soit fermé autant que possible de manière étanche à ses extrémités et à sa partie inférieure. Une surpression qui sert à alléger le poids inhérent du rouleau (R) peut être générée dans l'espace (DR). Cette combinaison de mesures permet d'éviter des poches d'air indésirables.

Granted: 2007-05-15
Abstract: The remote interrogation system has multiple tags responding simultaneously to a single query from the interrogation post. The tags are initially synchronised by a single command from the interrogation post. The synchronisation for the tags involves counting of the cycles of an alternating signal and determining the polarity of a particular half-cycle. The tag then responds on that particular half-cycle. The tags respond at a transmission frequency that is a sub-multiple of the transmission frequency from the interrogation post. The interrogation signal is emitted in sequence in different directions.
