A tool holder for holding a tool has at least one sensor for measuring an operating parameter of the tool holder or the tool during the operation thereof and generating measured value signals which are fed to a signal processing unit for evaluation. The sensor is a surface acoustic wave sensor operating according to acoustic wave principles and its measured value signals are readable in a contactless manner by means of radio waves. The surface acoustic wave sensor requires no current supply circuit but instead draws transmission energy required for transmission of the measured value signals to the signal processing unit from a high frequency interrogation signal, that is transmitted by radio waves from the signal processing unit and is received by the surface acoustic wave sensor.
摘要:
A coding scheme is specified which, compared to the prior art and with the system having a structure resolution of the same magnitude, allows an enlarged code size for the same number of code elements, and/or by which fewer code elements are required per code for a predetermined code size. The code elements are disposed with basic values in a matrix defined in a novel manner, with the matrix having a finer subdivision of the basic values than the subdivision corresponding to the structure resolution. Further development with mean-value formations are possible.

摘要:
The invention relates to the production of novel proteins exhibiting bonding activity for certain ligands, the so-called anticalins. To this end, the structure of peptides of the lipocalin family is modified by amino acid replacement in their natural ligand binding pocket using generic engineering methods. Alike immunoglobulin, the anticalin thus obtained can be used to identify or bond molecular structures.
摘要:
An electromagnetic energy transducer configured to convert mechanical energy into electrical energy comprises two magnetic elements including a permanent magnetic element and a soft-magnetic element and an electrical coil. The permanent magnetic element and the soft-magnetic element are arranged to form a magnetic circuit and one of the two magnetic elements is movable in relation to the other of the two magnetic elements. The electrical coil surrounds a part of the soft magnetic element. The movable magnetic element is held in a first position by a spring force and moved into a second position by applying an external mechanical force exceeding the spring force, and at the first position the magnetic flux within the soft magnetic element is different than the flux at the second position.
