Abstract: A laser for generating pulsed laser radiation. An element is arranged in the resonator to generate laser radiation having the first wavelength by frequency conversion of the primary radiation. The resonator is switchable into a first state in which it is open to the primary radiation, and a second state in which it is closed to the primary radiation, and is open to laser radiation of the first wavelength in both states. A control unit switches the resonator from the first to the second state so that the primary radiation begins to oscillate and the pulse generation by frequency conversion begins, switches the resonator from the second to the first state, whereby primary radiation is coupled out from the resonator. It is possible to set the duration between both steps and/or the coupling-out behavior of the resonator to adjust the pulse duration via the control unit.

Abstract: In a method or device for transport of liquid developer to an image carrier element for electrophoretic digital printing, a developer unit is arranged adjacent to the image carrier element, the developer unit directing a liquid developer having toner particles to the image carrier element, the toner particles crossing over to the image carrier element corresponding to previously-generated potential images. A raster unit is arranged adjacent to the developer unit. The raster unit transports the liquid developer to the developer unit by use of a raster. An electrical voltage is applied between the raster unit and the developer unit in order to exert a targeted field effect on the toner particles in a direction towards the developer unit. A chamber scraper having a dosing scraper is arranged adjacent to the raster unit and having liquid developer having the toner particles which are already charged. From the chamber scraper the raster unit accepts the liquid developer via the dosing scraper.

Abstract: In a method for suppressing interferences while detecting objects in a target area, a transmitter transmits a sequence of pulses into the target area, and a receiver detects the resulting reflection signal of the pulses reflected from the objects, within successive time windows that are referenced to the moment of transmitting an individual pulse and thus represent distance gates. The time spacing between the successive individual pulses is variable and randomized according to the pseudo-noise principle within predetermined limits, and the time windows are adapted accordingly. The received reflection signal may be sampled, digitized, digitally pre-processed and digitally filtered in the individual distance gates. A non-linear digital filter, preferably a sliding median filter, is used for the filtering to suppress transient disturbances. The median is determined from an odd number of consecutive sampled values of a reflection signal detected within a distance gate.

Abstract: A transfer apparatus has a drive disk rotatable at a transfer station about a central axis and defining an eccentric axis offset from the central axis. An inner drive shaft centered on the eccentric axis is rotatably journaled in the drive disk at the eccentric axis. An inner arm is fixed to and extends angularly from the inner drive shaft. An outer arm is pivoted at the inner-arm outer end, and a grab is pivoted on the outer-arm outer end. A drive rotates the drive disk about the central axis and thereby orbits the inner arm, the outer arm, and the grab about the central axis. An inner controller changes an inner angle formed between the inner arm and the outer arm, and an outer controller changes an outer angle formed between the grab and the outer arm.

Abstract: Computer systems with multiple users will typically store various versions of the same software; different versions being required for different platforms and to maintain compatibility with other software applications. These computer files are generally organized in a hierarchical structure to make their location and access easier, but this still results in a very complicated and inefficient system. The invention provides a custom file system which allows each user, node or system, to identify and manage only the files that are pertinent to it. This custom filesystem provides a custom hierarchical structure of files and folders, and links back to the real file locations in the main file system. The custom file system has priority over the main file system, in that a process manager will attempt to address requests on the custom filesystem before trying to place them on the main filesystem.

A control device for controlling the first and the second incident illumination device and the at least one image sensing device is furthermore provided.

Abstract: A system for meeting demanding boot time requirements, such as those timing requirement mandated by vehicle telematics systems, is described. Current computer systems use expensive hardware like coprocessors to service requests, such as input/output requests, that have timing requirements which are less than the time required to load the operating system into memory. Instead, a mini-driver may be initialized early in the boot process before the operating system is loaded, to service these requests. For example, the mini-driver may buffer incoming data, and/or reply to incoming messages. After the operating system has loaded, a second device driver may be initialized, and the mini-driver may be transitioned to the second driver.

Abstract: This invention provides a system for speech recognition comparing speech against stored character strings in memory. Speech is transformed into spoken character strings. To accelerate the identification, a small group of characters from the stored character strings and the spoken character string are compared and the probabilities for identification may be calculated from those results. Those stored patterns, where the probability for identifying the speech exceeds a predetermined value, may be selected for further processing. The selected strings may have the remaining characters added to the group of characters for the next comparison. Alternatively, the number of characters for comparison may be incremented by a predetermined number in a step-by-step fashion, reducing the number of comparisons in subsequent steps as the probabilities for identification rise.
