Granted: 1996-12-24
Abstract: Solenoid control circuitry can be used with either a first solenoid requiring a relatively large holding current or a second solenoid requiring a relatively small holding current.  A solenoid connected with the solenoid control circuitry is initially energized to effect operation of the solenoid from an unactuated condition to an actuated condition.  A detector detects whether a characteristic of the initial energization of the solenoid corresponds to a characteristic of the first solenoid or the second solenoid.  The solenoid control circuitry varies the amount of holding current supplied to the solenoid as a function of whether the detector detects the first solenoid requiring the relatively large holding current or the second solenoid requiring a relatively small holding current.  A fault detection circuit is provided to interrupt energization of the solenoid in the event of an excessive flow of current.

Abstract: In a method for preparing coffee drinks with the help of a plu-rality of coffee powder portions arranged along a transporting tape, a single coffee powder portion is removed from a storage container by pulling out the transporting tape to such an extent that the following coffee powder portions remain in the container.          Then, the tape is cut behind the first coffee powder portion, and the new initial portion of the transporting tape is fixed in the region of the outlet opening of the container. In this way, the unused coffee powder portions remain fresh and keep their full flavor, even during an extended storage period.   The coffee machine suitable for performing this method com-prises a two part brewing chamber. One portion of the brewing chamber is not only movable to and fro the other portion, but also rotatable and furthermore equipped with a catch member for grasp-ing the initial portion of the transporting tape.

Abstract: A distributed feedback semiconductor laser selectively performs one of two oscillations in different polarization modes having different polarization planes.  The laser includes a subtrate, a light waveguide formed on the substrate, which at least partially includes an active layer, a a diffraction grating formed around the waveguide, and an injecting unit for injecting a modulation current into a portion of the waveguide.  The waveguide and the grating are constructed such that oscillation wavelengths of the polarization modes are different from each other and minimum values of threshold gain in the polarization modes near the Bragg wavelength are approximately equal to each other. The semiconductor laser can be driven by a minute modulation current and prevents degradation of response characteristics due to dynamic wavelength fluctuation in a high-frequency range when used in optical communication systems in which the switching of polarization mode is performed.

Abstract: The radial pneumatic tire of this invention has a reduced bead mass and improved rolling resistance. This is accomplished with less than a 5 percent reduction in the ability of the tire to sustain nominal loads and maintain tire endurance. The bead area has a profiled bead filler that extends radially outward from the apex portion with an essentially constant thickness portion and a tapered portion.      An outer filler strip extends from a point radially inward of the rim flange near the bead core radially outward to a position near the mid height of the tire. The end result is a tire with smaller standard architectural components but very efficient load supporting and endurance capabilities. In one embodiment the outer filler strip extends radially outward beyond the radial extent of the bead filler. In an equally effective embodiment the bead filler extends radially outward beyond the radial extent of the outer filler strip. The total bead mass is reduced by as much as 15 percent and rolling resistance is reduced by as much as 5 percent for the reduced bead mass tire of this invention.

Abstract: Dans la zone de l'interface utilisateur de systèmes informatiques, les volumes de données à traiter sont importants. Le processeur central se trouve de ce fait sans cesse surchargé, ce qui réduit fortement la capacité de calcul à disposition pour l'application effective et fait que la capacité de calcul ne peut être prédite sans limiter les demandes des utilisateurs. La nouvelle architecture informatique doit permettre d'obtenir des capacités plus élevées et pouvant être prédites de façon plus précise. Afin de supprimer les dépendances du reste du système vis-à-vis de l'interface utilisateur, l'ordinateur est subdivisé de manière à ce que la partie 1 se charge des tâches de l'interface utilisateur en termes d'affichage et de fonction, que la partie 2 assume la prise en charge des programmes d'application sans leurs surfaces utilisateur et que la partie 3 se charge des autres unités fonctionnelles. Toutes les parties possèdent leurs propres chemins de données internes. Une interface située entre la partie 1 et la partie 2 assiste l'échange d'information et de données, sans altérer le déroulement indépendant des processus dans les différentes parties. La partie 1 et la partie 2 possèdent leur propre chemin d'accès à des dispositifs communs situés dans la partie 3.

Title: Data security scheme for point-to-point communication sessions
Inventor: KAUFFMAN MARC W
IPC: H04N7/16
Filed: 1996-04-01
Granted: 2002-12-24
Abstract: Secure point-to-point communication of information to specific terminals is provided via a shared network. Far in advance of the establishment of an information session with a particular one of a plurality of terminals, a unique session identifier is securely delivered to the terminal by a highly secure entity. Information to be provided to the terminal is subsequently encrypted under the session identifier of that terminal by an insecure connection manager. The encrypted information is inserted into designated locations in a signal multiplex. The signal multiplex is transmitted over a portion of the network serving the terminal that is to receive the information. The terminal is informed of the designated locations of the encrypted information in the signal multiplex and of a transmission frequency at which the signal multiplex is carried on the network portion. The terminal tunes to the transmission frequency to locate the signal multiplex, recovers the encrypted information from the designated locations in the multiplex, and then decrypts the information using the terminal's unique session identifier.

Granted: 2006-11-28
Abstract: Une barre oscillante est décrite qui est destinée à être utilisée pour relier ensemble des extrémités adjacentes de segments d'une courroie sans fin. La barre oscillante a une aiguille constituée par au moins un filament ayant un diamètre externe sensiblement identique au diamètre de l'ouverture tubulaire formée par les boucles entrelacées utilisées en tant que couture aux extrémités adjacentes des segments devant être reliés. Celle-ci a également un tuyau de descente réalisé en un matériau rigide ou semi-rigide. Ce tuyau de descente a un diamètre externe inférieur au diamètre externe de l'ouverture tubulaire. Celui-ci agit en tant que guide pour faciliter l'insertion de l'aiguille à travers l'ouverture tubulaire formée par les boucles. Un redresse-tube relie ensemble l'aiguille et le tuyau de descente. Ce redresse-tube est constitué par une canalisation ayant une partie avant et une partie arrière dans laquelle l'extrémité arrière du tuyau de descente et l'extrémité avant de l'aiguille sont respectivement redressées. L'extrémité avant de l'aiguille a une cavité périphérique dimensionnée et conformée pour recevoir la partie arrière du redresse-tube et empêcher ainsi ce redresse-tube d'avoir un diamètre externe dépassant le diamètre externe de l'aiguille. Cette caractéristique rend l'insertion de la barre oscillante bien plus facile à effectuer. La partie avant du redresse-tube a également un bord avant qui est biseauté vers le bas vers l'avant. Cette caractéristique réduit le risque d'endommagement des boucles.
