摘要:
The present invention aims at avoiding fragmentation during transmission of a structured document (10). This is achieved by a method of progressive transmission for a structured document (10). the structured document (10) comprising sub-documents (12, 14, 16, . . . ) with related relevance weightings. In particular, a fragmentation measure is determined according to the transmission sequence in an automatic manner using a formal expression of fragmentation. After comparison the fragmentation measure with a predetermined threshold value the transmission sequence is modified to reduce fragmentation when the fragmentation measure exceeds the threshold value.

In one embodiment, a system for providing electrical energy to a traveling spark ignitor operating in an internal combustion engine is disclosed. The system may include a conventional ignition system connected to the ignitor and a follow-on current producer which produces a follow-on current that travels between electrodes of the ignitor after an initial discharge of the conventional ignition system through the ignitor. The system may also include a disabling element that prevents the follow-on current from being transmitted to the ignitor. The disabling element may prevent the follow-on current from being transmitted to the ignitor based upon current operating conditions of the engine. When the disabling element prevents the follow-on current from being transmitted to the ignitor the system operates in a conventional manner. When the disabling element allows the follow-on current to be transmitted to the ignitor the system operates in a in manner that creates a traveling spark between the electrodes of the ignitor.

The invention is directed to a method and an arrangement for the response analysis of semiconductor materials with optical excitation. The object of the invention, to find a new type of response analysis of semiconductor materials with optical excitation which also allows a sufficiently precise detection of the charge carrier wave with a higher excitation output and a shorter charge carrier lifetime, is met according to the invention in that an exciting laser beam is intensity-modulated with two discrete modulation frequencies (.OMEGA..sub.1 ; .OMEGA..sub.2), the luminescent light exiting from the object is measured on the difference frequency (.OMEGA..sub.1 -.OMEGA..sub.2), and the luminescent light is analyzed as a function of the arithmetic mean (.OMEGA.) of the modulation frequencies (.OMEGA..sub.1 ; .OMEGA..sub.2). The invention is applied in the semiconductor industry for determining different electrical parameters of semiconductor materials.

A process and arrangements for photothermal spectroscopy (thermal wave analysis) by the single-beam method with double modulation technique. A single-beam method is developed making use of the advantages of double modulation technique in detecting the photothermally generated difference frequency without requiring partial beams and while achieving extensive absence of intermodulation, the intensity of the laser beam is modulated before striking the object in such a way that the modulation spectrum substantially contains a carrier frequency (f.sub.1) and two sideband frequencies (f.sub.1 .+-.F.sub.2), wherein f.sub.2 is the base clock frequency of the modulation, a regulating detector and a control loop intervening in the modulation process suppress that component of the base clock frequency (f.sub.2) in the same phase with the mixed frequency of the carrier frequency and sideband frequencies. After interaction with the object the optical response of the object is measured by means of a measurement detector and frequency-selective and phase-selective device as the amplitude of that component of the base clock frequency (f.sub.2) which, as the photothermal mixed product, has the same phase as the mixed frequency of the carrier frequency (f.sub.1) and sideband frequency (f.sub.1 .+-.f.sub.2). Use for nondestructive and noncontact analysis of the material parameters of areas of solid bodies close to the surface is described.

The invention concerns a method for the authentication of users of a hybrid terminal with a first registration step. The first registration step comprises entry of user identification data, request to enter a personal identification number, forwarding of the personal identification number to a registration server of an authentication apparatus, forwarding of the user identification data, validation of the user identification data, generation of a registration code, and in the event that entry of the personal identification number has not taken place, generation of the personal identification number, forwarding of the registration code to the internet-capable terminal and in the event that entry of the personal identification number has not taken place, forwarding of the personal identification number via a separate connection to the user. The method also comprises an authentication step comprising checking whether a profile file is present on the hybrid terminal, carrying out an authentication in order to establish whether the user is authorized to receive user data from the service provider and/or to send user data to the service provider, or otherwise carrying out an initial authentication and, if necessary, generation and transfer of the profile file. Furthermore, the invention concerns a corresponding apparatus for carrying out the method.

This disclosure concerns a cytometry system including a handling system that enables presentation of single cells to at least one laser source. The laser source is configured to deliver light to a cell within the cells in order to induce bond vibrations in the cellular DNA. The system further includes a detection facility that detects the signature of the bond vibrations, wherein the bond vibration signature is used to calculate a DNA content carried by the cell.
摘要:
An imaging device has a thermal sensor to remotely measure respective temperatures of regions within an imaging field and to generate temperature information signals. A motion tracking system tracks motion of the thermal sensor and generates position information signals representing positions of the thermal sensor during the temperature measurements. An image construction processor uses the position and temperature information signals to generate a two-dimensional image representative of the imaging field including respective temperature indications at different locations within the two-dimensional image, and stores the two-dimensional image within a memory. The two-dimensional image may be used as an output image for display to a user.
摘要:
A system for a Fischer-Tropsch synthesis using a three-phase reactor in which a primary filter removes coarse catalyst particles from the product and in which catalyst fines are removed in a secondary filter. Some or all portion of the product wax from the secondary filter can be recycled back to the reactor, either as a back flush medium for the primary filter or directly to the slurry in the reactor, whereby removal of catalyst fines is rendered independent of the rate of wax production.
