Inventor: KOSTKA GUENTHER
IPC: A61B6/14
Filed: 1997-10-23
Abstract: The inventive device for digital dental radiography has a source of X-radiation, a detector device, a correcting device and a temperature control device. Said detector device consists of a CCD array on which a scintillator layer is arranged and the radiation geometry of the detector device is constant in relation to the source of X-radiation. The correcting device corrects the electrical signals generated by the CCD array by compensating fluctuations in the electrical signals of the individual elements of the CCD  array caused by a dark current of said array elements, by the array elements having different degrees of conversion efficiency and by the inhomogeneity of the scintillator layer. The temperature control device ensures that the detector device remains at a constant temperature during the detection of reference signals and image signals.

Title: Method to control data reception buffers for packetized voice channels
Inventor: WOOD ROBERT GEOFFREY
IPC: G06F5/06
Filed: 2000-05-17
Abstract: A method is provided for avoiding data loss in a data packet switch which utilizes a circular data buffer. If the data is received at a faster rate than it is read out of the buffer the data read-out pointer is adjusted by incrementing it to skip, or drop, the next sample. If the data is received at a slower rate than it is read out of the buffer, then the read-out pointer is adjusted by decrementing it to repeat the previous sample. The method of controlling the buffer read-out pointer according to the present invention, is implemented in hardware thereby reducing system complexity and improving speed relative to prior art software solutions.

Abstract: La présente invention exploite les principes de l'évolution, responsables du développement du système de détection d'odeur général à large spectre, pour créer un système basé sur un récepteur couplé de protéine G (GPCR) apte à détecter et à discriminer des milliers de substances chimiques. Les moyens utilisés consistent à soumettre un ensemble défini de récepteurs, tels que des récepteurs couplés de protéine G, des récepteurs tyrosine kinase, et/ou des canaux ioniques, aux forces évolutives du type de celles qui ont créé la matrice d'environ 1000 récepteurs naturels utilisés par le système olfactif des animaux supérieurs. Cet objectif de création d'un capteur est accompli par "évolution dirigée dans un tube test" en imposant des taux de mutations élevés et des critères de sélection extrêmement stricts. Le nouveau capteur est choisi à l'aide d'un biotest fonctionnel basé sur un mélanophore sensible. La stimulation du capteur lors d'interaction avec des signatures chimiques, provenant d'ordonnances, libère un flux d'ion calcium rapidement détecté par un signal fluorescent.

Abstract: A method and apparatus for insuring authenticity for consumer goods as well as products transferred to another party. In one embodiment, a record of authenticity is provided with a good at the point of manufacture. The record of authenticity includes an item code and a registration number unique to the good. An Internet database stores the authenticity data. Once an article or good is purchased, the owner of the article accesses the database and is forwarded a second registration number which is different from the initial registration number provided at the point of manufacture. The owner may register as a legitimate owner of authentic goods by entering the new registration number and item code as well as other information. This information is stored in the Internet database for the good in issue. The system also provides for insuring that any good transferred in title to a second party is an authentic article and also lists information for this party relative to the article.
