Filed: 1994-08-16
Granted: 2005-03-29
Abstract: A digital signature method based on the discrete logarithm problem is provided that allows message recovery. The message x is transformed according to the rule a = x g -r mod p, where r is a secret value generated by the signer. A value y is then calculated according to the rule y = r + s e mod q, where y is the signer's secret key. The signature of x consists of the pair (e,y). The verifier recovers the message x according to the rule x a g y k e mod p, where k is the signer's public key. The validation of x can be based on some redundancy contained in x. Alternatively, a conventional verification equation can be constructed by using the signature method together with a hash function H. In addition, a key agreement method based on the signature method is provided which establishes with a single transmission pass a shared secret key K between two parties A and B in an authenticated fashion.

Abstract: A carrier frequency based system employs a capacitive probe which is located at a predetermined desired fluid detection level in a fluid containing vessel. The probe forms one plate of a capacitor where the other plate is formed by the fluid in which the probe is immersed. A carrier frequency is injected into the fluid by means of a suitable oscillator and at a frequency which is close to the system resonant frequency. When the probe is immersed in fluid, the probe will receive a predetermined carrier frequency of an amplitude determined by the system. The output of the probe is coupled to suitable sensing circuits which monitor the amplitude of the signal frequency coupled to the probe. When the fluid level recedes and therefore a portion of the probe or the total probe is out of fluid, the capacitance of the system changes. A different signal from the injected carrier frequency is now applied to the probe indicating to the sensing circuit that the probe is not immersed and therefore indicating an alarm condition. The output of the sensing circuit is monitored by control circuitry which can operate an alarm indicating to the user that the probe is not fluid immersed and that preventive measures should be taken. The fluid sensing probe utilizing the carrier injected frequency can discriminate between fluid and foam, "probe fouling" and probe shorting and is relatively fail proof as compared to prior art systems.

Abstract: Ce systeme et ce procédé permettent de détecter automatiquement des zones définies par un utilisateur dans une image d'un document tel qu'un formulaire, en compensant l'inclinaison et le déplacement de cette image par rapport à une image originale du formulaire. Ce système comprend un mécanisme d'introduction d'images dans un document tel qu'un formulaire, un scanneur par exemple. Ce système traite l'image pour en réduire la résolution et en supprimer une inclinaison significative. L'image est présentée à l'utilisateur qui y définit des zones, à savoir des endroits dont il souhaite extraire, par reconnaissance optique de caractères, des données significatives telles que noms, dates, adresses et articles indiqués sur une facture. Ce système traite aussi l'image pour en supprimer les lignes horizontales et verticales et pour créer un certain nombre de blocs représentant des données d'image ou de texte. Ces lignes sont supprimées et les blocs sont formés par lissage de longueur de passe avec différents paramètres. Ils constituent des ensembles de pixels reliés et sont étiquetés de façon que tout jeu de blocs reliés partage une valeur d'identification unique. Des données supplémentaires sont collectées sur ces blocs à étiquetage commun, ce qui permet de choisir ceux des blocs utiles pour définir un gabarit qui est constitué d'un ensemble de vecteurs placés entre les centres de gravité de chacun des blocs choisis. On obtient une deuxième image de document, qui est traitée de la même manière pour en réduire la résolution et la redresser, et pour qu'y soient identifiés des blocs et des vecteurs. Les vecteurs de cette deuxième image de document sont comparés à ceux d'un gabarit sélectionné par l'utilisateur, ce qui permet de déterminer dans cette image l'emplacement de zones définies par l'utilisateur.
