摘要： The invention relates to a device for measuring current which traverses a light-emitting structure, the current passage thus causing emission of light. It is characterized in that the emitted light signal is adapted to be supplied to two photo-detectors having different sensitivity spectra and/or with at least one photo-detector being provided with an optical filter. The output signals of the photo-detectors are adapted to be supplied to a quotient forming member and/or a calculating member for obtaining a signal which is compensated for temperature variations in the light-emitting structure and other sources of error.

摘要： A fiber optical measuring device for measuring a magnetic or electric field comprises an optical modulator influenced by the field. The optical properties of the modulator are dependent on the magnetic or electric field acting on the modulator. The optical property which is made use of is the field dependence of at least one absorption edge of the radiation absorption spectrum of the modulator material. Optical fibers may be used for feeding light into the modulator and for leading away light that has passed through the modulator.

摘要： A robot having a force sensor and a tool fixture for operating on a workpiece that may have a complex surface contour is programmed by an operator first teaching the robot by a suitable technique such as lead through teaching a few gross points of the contour. These points, known as guiding points, are used to generate a program to be followed by the robot under the control of the robot controller and using force control during which the robot finalizes the guiding points and teaches one or more points on the contour intermediate adjacent guiding points. The controller or other computing device uses the points so taught to generate the path the robot tool fixture will follow when the tool is to operate on the workpiece.

摘要： An industrial robot that uses a simulated force vector to allow a work piece held by the robot end effector to be mated with a work piece whose location and orientation is not precisely known to the robot. When the end effector makes contact with the location and orientation in which the other work piece is held the robot provides a velocity command to minimize the force of the contact and also provides a search pattern in all directions and orientations to cause the end effector to bring the work piece it is holding in contact with the other work piece. The search pattern and the velocity command are continued until the two work pieces mate.

摘要： A sensor element adaptable for measurement of a physical parameter formed of a crystalline material and emitting luminescent spectra upon excitation by light spectra and the influence of said physical parameter. A first layer emitting luminescent spectra is formed of a semiconductor material containing dopant providing shallow energy levels and recombination centers with a concentration between 10.sup.15 to 10.sup.18 cm.sup.-3, and sandwiched between second and third layers of semiconductor material having low absorption for light excitation of the first layer, and the respective lattice constants of the second and third layers being substantially coincidental with the lattice constant of the first layer. The sensor element is formed of GaAs for the substrate and AlGaAs for the semiconductor layers, with appropriate variation in the concentration Al, Ga, and As for the various layers. Generally, the energy band gap of the layers sandwiching the luminescent emitting layer are higher than that of the emitting layer. In a modified embodiment, GaAs is used as the luminescence emitting layer with covering semiconductor layers of AlGaAs, with appropriate variation in the concentration of Al, Ga and As. In a further modification an additional semiconductor layer of AlGaAs is sandwiched between the active semiconductor layer and a non-active semiconductor layer to reduce or eliminate a shift in the wavelength emission of the sensor element.
