摘要:
A target plate (Z) according to the invention for positioning components, in particular pipes (R1, R2), has a holographic optical element as a holographic diffusor. By means of the diffusor, radiation striking the target plate (Z) in the form of a reference beam (RS) can be guided very accurately and virtually without loss into a defined solid angle region (dΩ). Furthermore, the diffusor may have stochastically distributed structures and thus illuminate the solid angle region (dΩ) homogeneously. By means of the target plate (Z), the visibility of the incident reference beam (RS) is increased, and the reference beam (RS) can also be detected independently of position.

A method of protecting a microcomputer system against manipulation of data stored in a storage assembly of the microcomputer system, in particular a control program stored there. Checking mechanisms are executed at preselectable points in times to check for manipulation of the data. To achieve the most complete test coverage within an acceptable period of time in checking data stored in a storage assembly of a microcomputer system, the storage assembly is subdivided into multiple logic blocks, at least one of the blocks is selected and the checking mechanisms are executed only for the or each selected block of the storage assembly.

A method is provided for controlling a microcontroller in a control unit in a motor vehicle, having a processor core, at least one read-only memory area and at least one rewritable memory area, at least one control program which is intended to be processed by the processor core being stored in the rewritable memory area. In order to provide a method for controlling a microcontroller in a control unit that better protects the verification of memories of the microcontroller against unauthorized intervention, a verification program is stored in a write-once memory area of the rewritable memory area and a service program is stored in the read-only memory area. The verification program is called by the control program via the service program at regular intervals and verifies at least part of the rewritable memory area. In addition, the service program resets a counter. A RESET of the control unit is triggered by the verification program when manipulation of the verified memory area is detected or by the counter in the event of counter overflow.

The invention relates to an electronic display and control device for a geodesic measuring device containing capturing means and representation means for detecting and reproducing a measuring range together with input means for controlling the measuring processes. The radiation beam necessary for said measuring processes is emitted by a radiation source and is influenced in the direction of emission thereof by orientating means such that it can be orientated onto a selected target within the measuring range without the capturing means being displaced. Determining the target and initiating the measuring process occurs by displacing a position mark on a screen. A suitable operating module con be produced by suitably combining the representation means with means for inputting data. Said module can also be used independently from and separately from a measuring device which is connected thereto by communication means. The use of said module together with a plurality of measuring devices as sensor components, enables the formation of remote-controlled geodesic measuring systems.

摘要:
The invention pertains to a process and a device for determining the composition and concentration of elements in material samples using laser-based plasma emission spectroscopy. The process comprises the following steps: a) transformation of a portion of the material sample (20) to be analysed to a plasma-like state (46) by means of a pulsed high-power laser (12) focussed on the material sample (20); b) spectral analysis of the radiation emitted by the plasma (46) using a spectrometer (26); c) measurement of the total emission spectrum (44) of the plasma (46) changing per laser pulse in one or more spectral ranges typical of the element, using a detector (40); and d) calculation of the composition and concentration of the elements based on the entire spectrum (44) of measured emissions, i.e. the sum of a number of measured individual spectra (42). The claimed device (10) comprises a high-power laser (12), a spectrometer (26) and at least one measuring head (14) with integrated radiation optics (22). The high-power laser (12) and the spectrometer (26) are geometrically and stereoscopically decoupled from the measuring head and are connected to each other via at least one waveguide.

摘要:
Systems and techniques for information centric network (ICN) heterogeneous wireless switching are described herein. A handover event, that includes an indication for a device to switch from a first wireless link to a second wireless link, may be detected. A forwarding interest base (FIB) table may be modified to route interest packets to the second wireless link. Although the device has switched to route new out-going interest packet to the second wireless link, the device accepts data packets on both the first wireless link and the second wireless link.
