Abstract: A computer apparatus and method for generating structures and analyzing the stability of a structure formed from multiple predefined components represents the structure as a series of bodies fixed in place by stationary joints. The joints have known properties and each joint is assigned a torque capacity corresponding to the known properties. A computer routine calculates torque exerted on each joint and compares the calculated torque with the torque capacities to determine stability of the structure. The computer routine enables remodeling of an unstable structure.

Abstract: The present invention relates to methods and to arrangements for monitoring an object which emits a rotating or oscillating beam whose angular velocity is unknown. The time points at which the beam passes a predetermined number of measuring positions are determined. An angular velocity start value is generated and a predetermined number of object position determinations (at least two independent determinations) are made on the basis of the determined time points, the measuring positions and the start value. It is determined whether or not the position determinations can be considered to be sufficiently in agreement with one another. When agreement is considered sufficient, the start value is accepted as an approximate value, this value approximating the angular velocity of the beam with an acceptable degree of accuracy. If the position determinations are not found to be sufficiently in agreement, the start value is modified and new position determinations are made.

Abstract: A device for model-based diagnosis of a technical system, wherein the device determines which parameter is to be measured as the next one, and derives further parameter values from values for specific parameters. For these values, a process often referred to as the “propagation of values” employs a library with models of the component types and a model for the design of the technical system. The purpose of its device is to efficiently store information about measures with which parameters values are determined, and to quickly evaluate the determined values. This information establishes under which prerequisites measures may be implemented, and what their implementation costs. One aspect of the invention establishes that and how this information is stored in libraries of component types so as to be re-used. The primary advantage: the cost of producing the diagnosis device is reduced significantly in comparison to the state of the technology.

Abstract: A method of detecting abnormalities including a learning phase and an inspection phase. In the learning phase, a first statistical quantity and a second statistical quantity are determined based on a first set of n-dimensional data. A second set of n-dimensional data is obtained and a bimodal distribution for a plurality of n-dimensional points in each of the second set of n-dimensional data is determined. A reference template is generated in response to the first statistical quantity, second statistical quantity and bimodal distribution. In the inspection phase, n-dimensional test data to be inspected for abnormalities is obtained and compared to the reference template to detect abnormalities.

Abstract: An arrangement for measuring the direction of the geomagnetic field {right arrow over (B)}E, in the proximity of a magnetic jamming device with a magnetic field direction variable as a function of time, which is distinguished by the fact that at least two magnetic field measuring devices are provided, each of which measures all three vector components of the total magnetic field ({right arrow over (B)}1,{right arrow over (B)}2), the magnetic field measuring devices have a position, ({right arrow over (r)}0,{right arrow over (r)}1,{right arrow over (r)}2) which is invariable as a function of time and is fixed relative to one another and relative to the jamming device, and the measured values can be called up synchronously and can be evaluated according to {right arrow over (B)}E=({right arrow over (B)}1+{right arrow over (B)}2)/2+P·({right arrow over (B)}1−{right arrow over (B)}2), P({right arrow over (r)}0,{right arrow over (r)}1,{right arrow over (r)}2) describing the geometric

Abstract: A method for determining the wheel base of steerable vehicles when cornering, in which the wheel base is determined from at least one defined track width, measured wheel circumference speeds and/or measured steering angles.

Abstract: A method of determining remote gas concentration values from remote gas sensors. The method is particularly applicable to heated metal oxide sensors; however, it is not restricted to this type of sensor. A polynomial fit is made of a sensor's gas response curve for each sensor in the system. Usually this is a third order polynomial; however, any other order can be used. The sensors response at zero concentration is a zero or root of the polynomial. This root is factored out of the polynomial reducing it one degree. It is possible to factor out more than one real root if such a root is known further reducing the order of the polynomial. The coefficients of the reduced polynomial are scaled and stored as absolute values in binary words at the remote. At least one additional word is used to store exponents and signs. These words are transmitted to a central location on demand so that the gas response curve can be recreated.
