摘要:
An elevation measuring device (1) comprises a measuring column (3) at which a vertically movable measuring slide (4) is supported, so it can be moved by hand and also by a drive motor (14) through a clutch device (15). The measuring slide (4) supports a scan head (8), which imparts a constant measuring force onto the measuring location at the work piece, which is generated by the drive motor (14) and the clutch device (15). A measuring system (19) detects the elevation coordinate of the scan head (8) and hands said elevation coordinate to a control device (21) for further processing and evaluation. The control device (21) comprises logic (33) for automating the measuring process. This logic automatically detects a positioning of the scan head (8) in a certain direction, which is manually performed by the operator, subsequently controls the drive motor (14) in a suitable manner in order to cause a scanning of the work piece and determines the measurement values, which are relevant for the respective measurement, from the signals of the measuring system (19). The control device (21) can be configured to fully automatically detect the intention of the operator to measure either on a plane or in a bore hole or on a shaft, in one direction or in the opposite direction, and to independently initiate the intended measuring function.

A capacitive measuring device or apparatus; in particular, a length-measuring apparatus, which incorporates a scale portion and a scanning unit which is movable relative to the former and which supports transmitting electrodes and at least one receiving electrode. Herein, a transmission circuit applies transmitting signals at a basic frequency to the transmitting electrodes, and with the receiving electrode being connected to a reception circuit, to the output side of which there is connected an evaluating circuit for the receiving signals. The transmitting signals are applied to the transmitting electrodes through a pulse width modulator and a synchronous modulator and the receiving signal is conducted through a demodulator. The synchronous modulator and demodulator operate at the same modulation frequency, which is higher than the basic or basic frequency; and when the scanning unit is at a standstill relative to the scale portion, the base frequency of the receiving signal is equal to the base frequency of the transmitting signals, and upon movement of the scanning unit relative to the scale portion the basic frequency of the receiving signals changes in conformance with the speed of movement relative to the basic frequency of the transmitting signals, whereby a change in frequency is evaluated by the evaluating circuit so as to display the length or extent of the movement.

A distance measuring system (1) is provided with a capacitive sensor (7a, 7b), designed in the form of a differential capacitor (18), for which the partial capacitors (C1, C2 have capacitances that depend on the position to be determined. The system also includes a processing device (5) for determining the desired distance that contains, for example, a sigma/delta demodulator. The partial capacitors (C1, C2) are triggered periodically with binary signals, wherein the trigger signals from the one partial capacitor (C1) are transmitted with a phase offset to the signals from the other partial capacitor (C2). The processing device (5) determines which trigger signals must be used for the evaluation. Within time windows that are synchronized with the edges of the trigger signals, a switch unit (22) allows the associated receiving signals to pass through to the processing unit (5) and blanks out all other signals. The distance measuring system (1) makes it possible to have a low number of interpolation errors with high resolution and long interpolation periods. The distance measuring system (1) can be expanded by adding two essentially independent, parallel-operating relative measuring systems to form an absolute distance measuring system, which determines the absolute position solely from the current measuring values. A nearly optional enlargement of the measuring range is possible by adding further relative measuring systems.
摘要:
The invention relates to the identification and use of gene expression profiles with clinical relevance to the treatment of cellular proliferative disorders, especially those mediated by aberrant Notch signaling using a Notch signaling inhibitor. In particular, the invention provides the identities of genes, whose individual or cumulative expression patterns may be useful in various assays. The gene expression profiles, whether embodied in nucleic acid expression, protein expression, or other expression formats, may be used to select subjects afflicted with a Notch mediated cancer who will likely respond to treatment with a gamma-secretase inhibitor or another Notch inhibiting agent. The same markers may be used in the classification of patients being treated with other Notch inhibitors. The methods may further comprise providing diagnostic, prognostic, or predictive information based on the classifying step. The methods may further comprise selecting a treatment based on the classifying step.
