    摘要: A mobile telescopic crane has a telescopic jib with at least four part-jibs. Each of the part-jibs is constructed from at least two part-jib portions so as to be telescopic in a longitudinal direction. Part-jib portions arranged at a spacing from one another transverse to the longitudinal direction each form a jib portion with at least one flexurally rigid connecting element. A construction of this type of the jib means that an increase in the bearing load is easily achieved by increasing the area moment of inertia of the jib.

    摘要: Actual values of a load variable are detected by a sensor during active model trimming under different valve pressure conditions, and a model of estimated values is created. Trimming values of a model parameter are determined depending on detected and modeled values such that when the model parameter is trimmed, the modeled values approximate the detected values. A function is determined depending on the different pressure conditions and approximated to the trimming values. At different pressure conditions first lambda control values are detected. A first controller value fitted function is determined depending on the pressure conditions and approximated. When the model trimming mode is not active, second lambda control values are detected at different pressure conditions. A second controller value fitted function is determined depending on the pressure conditions and is approximated. An error of the intake system is detected depending on the fitted functions.

    摘要: The plasmon resonance sensor (1) comprises a chip (2) of transparent plastic with a gold layer (3) made up of narrow part surfaces (4), arranged in a row, on the inner side of which light from a planar light source (12) is convergently guided. A Fourier lens (24) integrated in the chip (2) forms the reflected angular spectrum on the detector (23), arranged at a focal separation (F) from the integrated Fourier lens (24) for temporal determination of the incident angle with a resonant intensity minimum of reflected light. An incident lens (13) brings about imaging of the planar light source (12) in the form of lines of light on the part surfaces (4), which are further imaged in the form of lines of light on the detector (23).

    摘要: Systems for controlling the motion of multiple articulated elements connected by one or more joints in an artificial appendage system. Four different embodiments are disclosed and include a controller that reduces the dimension of joint state space by utilizing biomechanically inspired motion primitives; a quadratic proportional-derivative (PD) controller which employs a two-stage linearization method, applies constraints to variables for dynamic stability, and employs a corrective “sliding control” mechanism to account for errors in the linear model used; a non-prioritized balance control approach that employs enforced linear dynamics in which all control variables are truncated to linear terms in joint jerks; and a biomimetic motion and balance controller based on center of mass (CM) energetic and biomimetic zero moment conditions.

    摘要: A circuit configuration having a filter, for example a bandpass filter, and a method for its operation are specified, which the circuit configuration allows for compensation of a frequency error, for example between an actual mid-frequency and a nominal frequency. A first mixer, upstream of the filter and a second mixer downstream from the filter are provided. A signal and a respective oscillation frequency are each supplied to respective inputs of the first and second mixers. The oscillation frequencies are mixed as a function of the frequency error in frequency generators such that the signal at the intermediate frequency is matched to the filter characteristics of the filter which is subject to tolerances. In consequence, filters that satisfy the stringent requirements for WCDMA mobile radio applications, but by virtue of the manufacturing technique, have an excessive mid-frequency error, can be used, for example, in heterodyne receivers.
