Abstract: A limit value detection device for multiple detection of a limit value event has a catch mechanism manufactured using microstructuring technology, having a first and a second catch element, each having a plurality of catches, a pawl configured to engage in a catch intermediate space between two adjacent catches of the first catch element, the first catch element being movable relative to the pawl in a freewheeling direction and movement thereof relative to the pawl in a blocking direction being blockable by the pawl, and an actuating device configured to move the first catch element and the pawl relative to each other in a catch-by-catch manner in the freewheeling direction. The first and second catch elements together form a counting unit in which the counter status for indicating the detected limit value events is determined based on the position of the two catch elements relative to each other.

Abstract: A MEMS actuator comprising a frame structure and at least one actuator arm. The actuator arm is connected at a first end to the frame structure and at a second end to an actuator body. The MEMS actuator is characterized in that the at least one actuator arm has a meander structure comprising two or more actuator sections. The two or more actuator sections are oriented substantially perpendicular to the longitudinal axis of the actuator arm. Furthermore, the two or more actuator sections comprise at least one layer of an actuator material, wherein a movement of the actuator body can be effected by actuating the two or more actuator sections. Further disclosed is a method for producing the MEMS actuator.

Abstract: A system for transmitting at least one upgrade package for at least one control device of a motor vehicle is provided.

Abstract: The invention relates to a leak detector comprising a first sensor for detecting a gas component (helium) in a gas taken in. Because the sensor is susceptible to saturation or contamination, a second sensor is provided. The sensor is a thermal conductivity sensor. The thermal conductivity sensor has a lower detection sensitivity, yet, at a high concentration of the gas component, it does not risk being contaminated. The two sensors together allow for a large detection range, from extremely sensitive measurements to instances with high concentrations of the gas components as those which can occur with gross leaks.

Abstract: A procedure for registering damage to a material including a metallic matrix and ceramic particles embedded in it. A volume-increasing phase change of the particles is suppressed by the pressure exerted on them by the metallic matrix. However, if a crack appears in the material, there is a phase change of the particles to a volume-increased phase which is detected by determining a measurement representing the proportion of the volume-increased phase.

Abstract: In a method for outputting data relating to user selectable information regarding a motor vehicle, a plurality of user selectable options relating to the information are represented, and data relating to the selected option is output. At least one context-dependent profile is defined, and a set of options determined by the profile is generated. Data are output as a function of the profiles and options.

Abstract: The present invention relates to a method for the selected chemical activation of photo-activatable cross-linker molecules around ligand binding pockets and fluorescent groups in macromolecules, especially biological macromolecules, by using fluorescent ligands of the macromolecule and by selecting photo-activatable cross-linker molecules having specific activation energies so that a radiationless energy transfer (Förster transfer) from the fluorescent ligands to the cross-linker molecules, which become activated thereby, takes place.

Abstract: Process for qualitative and quantitative detection of an analyte present in a biological sample and in molecular form, in which process a sensor is provided with a substrate binding the analyte and in which in a first process step the sensor is loaded with the analyte and, in a subsequent process step, the total analyte mass bound by the sensor is measured, before in a further step the molecular weight of the analyte forming the total mass is measured.

Abstract: A system and method for operating a remote control having a portable remote control unit which can control at least one function unit. The remote control unit and the function unit are connected with one another by way of a bidirectional data communication link, by which data can be transmitted by means of a symmetrical coding method. The remote control unit sends a learn mode reporting signal in a secret coding information learn mode to the controllable function unit which, in the learn mode, in turn, sends back an acknowledgment signal. Upon receipt of the acknowledgment signal, the remote control unit generates new secret coding information by means of the coding algorithm, as a function of basis secret coding information and of the previous secret coding information, and sends the new secret coding information to the function unit.
