Abstract: A method for determining the absolute value of a rotational angle includes imaging a continuous segment of a code track of a code carrier on a sensor array such that the sensor array generates a corresponding output signal. The code track includes a code provided over an angular range of 360°. The code contains a plurality of code words with each code word respectively corresponding to an angular value in the angular range. The output signal is correlated with a reference signal in a correlation filter to produce a correlation function signal. The reference signal is indicative of the code and the angular values corresponding to the code words. The correlation function signal is processed to determine the code word of the imaged segment of the code track as a function of the angular value where the output signal best coincides with the reference signal.

Abstract: A method for determining the absolute value of a rotational angle includes imaging a continuous segment of a code track of a code carrier on a sensor array such that the sensor array generates a corresponding output signal. The code track has a light and dark transition pattern over an angular range of 360°. The sensor array output signal is subjected to a convolution operation with a reference signal in a first correlation filter to reconstruct the light and dark transition pattern of the imaged segment of the code track as a first correlation function signal. The first correlation function signal is processed to determine a code word and a predetermined angle corresponding to the code word.

This invention has the goal of further developing such a process to make it possible to determine the influences due to mechanical tolerances, in particular for the purpose of subsequent compensation, and to do so without additional hardware expenditure.

Abstract: The invention relates to a process for determining the absolute value of a rotational angle, in particular the angular position of a motor vehicle steering wheel, by means of a transceiver comprising a light source and a sensor array having a multiplicity of optoelectronic transducers, and a code carrier arranged so that it can rotate with respect to it that has a unique, single-track encoding of the angular values, a continuous segment of the encoding being imaged on the sensor array, and the sensor array's output signal being evaluated to determine a code word corresponding to the current angular value. This invention has the goal of further developing such a process so as to achieve clearly increased insensitivity to outside influences, especially those caused by dirt or spurious electromagnetic pulses. This is achieved in a first correlation filter by subjecting the sensor array's output signal to a convolution operation with a reference signal to reconstruct the imaged segment of the code track.

Abstract: A new musical instrument comprises a thin solid or semi-hollow body and a triangular or trapezoidal frame across which a plurality of strings are disposed in the manner of harps. The instrument has frets, which allows the player a unique form of expression not available on harps. The instrument is small and light enough to be carried or held with a shoulder strap while being played, offering the player greater mobility. The instrument may additionally have built-in special effects that may be controlled by an expression control device or lever, offering the player even greater expression and mobility. The instrument also may have a special built-in hum and noise canceling preamplifier to improve the quality of the output signal. Certain additional design improvements and conveniences are provided for better playability and practicality.

Abstract: One embodiment of the present invention provides a system that facilitates cache coherence with adaptive write updates. During operation, a cache is initialized to operate using a write-invalidate protocol. During program execution, the system monitors the dynamic behavior of the cache. If the dynamic behavior indicates that better performance can be achieved using a write-broadcast protocol, the system switches the cache to operate using the write-broadcast protocol.

Abstract: The invention relates to a device for detecting the angle position of the steering wheel of a motor vehicle. The aim of the invention is to provide a device of this kind in which the technical problem of determining the absolute angle position of the steering wheel in a measuring range greater than 360° is solved without the need for mechanical reduction gears and such like. This is achieved by means of a measurement system comprising at least one coil system which cooperates with an electrically conductive structure configured on/in a flexible flat cable (6). The flexible flat cable (6) is wound in a winding gap situated between the outer lateral surface (3) of an inner cylindrical rotor (1) joined to the steering gear shaft and the inner lateral surface (4) of an outer cylindrical stator (2) joined to the steering column, in such a way that its one end is fixed to the rotor (1) and its other to the stator (2).
