Abstract: A sensing wheel for a device for measuring the rotational speed and/or rotational angle of a crankshaft of an internal combustion engine has a plurality of peripherally arranged teeth, which each have a front edge and a rear edge, which define the width of the respective tooth, and tooth gaps situated between the teeth. The front edges or rear edges of each of the teeth are spaced at basically the same angular interval from one another. A limited number of different tooth widths are provided over the entire periphery, the sequence of the tooth widths of at least three successive teeth over the entire periphery being unambiguous.

Abstract: A method and a device by means of which the response time of a software process is limited to a predetermined maximum response time is provided. The response time is the sum of latency time (period between triggering event and start of the process) and execution time. The software process is, for example, an interrupt service routine which is triggered by an interrupt request. According to the invention, the software process is subdivided into a number of partial processes which in each case supply a result. If the software process is terminated because the maximum response time has been reached, the result of a previously selected partial process is used as the final result of the process. This partial process is, for example, the one completely executed as the last one.

Abstract: A system and a method for managing and monitoring processor-internal memories of a process-executing unit or program unit, having a global stack memory area (1) for executing processes and sub-processes of a program sequence comprising different sub-processes, and a monitoring unit (2) for protecting and monitoring the address space of the stack memory area (1) between an upper limit (UL) and a lower limit (LL). The monitoring unit (2) has a separate, internal stack (3), which is adapted for storing a variable logical limit, e.g., the lower limit (LL), of the global stack memory (1) on each level of a nested arrangement of the program sequence in the transition between different processes. Data of a preceding process located on the other side of a stored variable logical limit, e.g., of a current process, are protected.

Abstract: A method for determining the performance of a battery for providing a vehicle power supply system voltage for a vehicle power supply system in particular in a vehicle, is provided in order to identify the serviceability of a battery in as simple and reliable a manner as possible, in which method the vehicle power supply system voltage (U) is recorded, in which process the vehicle power supply system voltage (U) and the vehicle power supply system current (I) are monitored for an operating mode which can be predetermined within a time window (Z) which can be predetermined, such that the vehicle power supply system voltage (U) at the end of the time window (Z) exceeds a limit value (G) which can be predetermined, as a function of the vehicle power supply system current (I) which is emitted during that operating mode.

Abstract: A module having an angle-sensor mechanism, an energy-transmission device and an information-transmission device comprises at least two circuit boards (1, 2). One circuit board (1) forms the stator with respect to the angle-sensor mechanism, while the other board (2) forms the rotor with respect to the mechanism. The stator includes the primary coil for the angle-sensor mechanism, as well as an exciting coil for the transmission of energy and information. The rotor includes the secondary coil of the angle-sensor mechanism, as well as a receiver coil, for the transmission of energy and information. The exciting coil and the receiver coil are disposed in circular fashion on the respective circuit board, thereby creating a coupling for the exciting coil and the receiver coil that is independent of the angle. The exciting coil and the receiver coil are used for transmitting both energy and information. The energy transmission is typically effected with a medium frequency of, for example, 25 kHz.

Abstract: An arrangement with a torque-controlled gearbox, for which the torque present on the transmission driving shaft is measured with a non-contacting torque sensor and the torque sensor supplies a measuring signal, which is fed to the gear control unit as a variable for the correct shifting moment. With a motor vehicle having an internal combustion engine, the drive output of the combustion engine is transmitted to the crankshaft, and the torque present at the crankshaft is transmitted via a clutch and an intermediate gear to the transmission drive shaft, from there to an output drive shaft, and finally via a differential gear to the drive wheels of the motor vehicle. The torque sensor detects the torque actually present at the transmission drive shaft and feeds the measuring signal proportional to this torque to a gear control unit. The arrangement advantageously permits a torque-free shifting of gears in the gearbox, which can thus be carried out comfortably.

Abstract: For reasons of flexibility, efficiency and costs, more and more processes are monitored with the aid of software-controlled electronic devices. As a rule, these are electronic devices that are controlled with the aid of microprocessors. The invention presented herein is aimed at increasing the reliability of these systems and, simultaneously, reduce the expenditure for developing these systems. A processor-monitoring unit is provided for this, which ensures a robust partitioning. This processor monitoring unit controls access to the memory and makes sure that the times for processing program segments and modules are observed.

Abstract: Each supply station has an assigned station number, and the respective carriages are positioned along both sides of an endless delivery belt for menu-component-receiving trays, and an electronic food service control is provided. Each carriage is divided into three sections with each section having three container areas therein with a respective signal lamp associated with each container area and mounted on a respective lamp arm, each lamp arm being associated with the respective section. Each section is arranged to receive either one full-size supply container, two half-size supply containers or three one-third size supply containers. A tray dispenser, responsive to a signal from the service control, delivers successive trays to the endless delivery belt. In a first step, the position of each tray is determined and stored and a menu request is read-in to the service control.
