摘要:
A phase locked loop has a controlled oscillator for outputting an oscillator signal depending on a control signal. A comparator generates a comparison result from a comparison between a reference frequency signal and a feedback signal derived from the oscillator signal. The phase locked loop also has a filter block for filtering the comparison result and for deriving the control signal from the comparison result, where the filter block has a loop filter and a rejection filter for the frequency-selective attenuation of at least one first interference frequency in the comparison result.

A feedback loop is used to determine phase distortion created in a signal by directly extracting the phase distortion information from a feedback signal using original frequency modulation information.

A method serves for the determination of the 3D coordinates of an object. An improved method of this kind is characterized in that the object is surrounded by a plurality of reference probes having coded reference marks; and in that a plurality of shots are taken of the object such that a part of the object and a part of a reference probe is in each case included thereon.

A structure for providing an optical effect includes first and second substrates hot stamped together by an adhesive. The adhesive includes an energy activated binder having a plurality of particles distributed therein or thereon for providing the optical effect detectable through the first substrate. The particles may be optically variable flakes, thin film light interference flakes, diffractive flakes, and reflective flakes.

A circuit for a micromechanical structure-borne sound sensor and a method for operating this sensor, a voltage generator being used to apply voltages to at least one micromechanical element for recording the structure-borne sound, so that a change in the micromechanical element occurs. In addition, an evaluation circuit is provided, which records the at least one electrically recordable parameter of micromechanical element at a sampling rate and analyzes the same. This at least one parameter changes in response to the change. A clock-pulse generator is also provided for generating the sampling rate and for generating the clock pulse. A frequency generator is used for generating the clock pulse at least intermittently for the test operation, the frequency generator producing the clock pulse as a multiple or as a submultiple of the sampling rate.

An oscillating circuit includes an analog oscillation element. The oscillating circuit includes at least one analog-to-digital conversion device. A method is for operating an oscillating circuit, in which a mechanical oscillator oscillates at a natural frequency. The oscillation amplitude is measured and digitized. A digital control signal is generated from this with the aid of a digital amplitude controller. A driving signal is generated, in turn, from the digital control signal, the driving signal driving the mechanical oscillator with the aid of a drive unit. This control loop stabilizes the oscillation amplitude.

Methods and systems for managing order document data are provided. The order document data may be represented as an object, the object being configurable so as to comprise a predetermined number of core components, the core components being configurable in their content, and being hierarchically ordered in a corresponding number of levels. The object may comprise a number of extensions. The core components may comprise a header, at least one item, and/or schedule line. The header may comprise central information about an order.
