A dental lighting system () for selectively illuminating a treatment site () on a patient sitting on a treatment chair (). The system includes at least one monitoring device (') configured to determine characteristics of a treatment site () on a patient and at least one lighting unit () configured to generate an illuminated area () onto the treatment site () by emitting a first light beam () in an upright state in which the treatment chair () is in an upright position and by emitting a second light beam () in a lying state in which the treatment chair () is in a lying position. The at least one lighting unit () is configured to set a shape of the illuminated area () based on the characteristics of the treatment site ().

In a method for determining the elongation of segments of a chain of a chain drive during operation, a plurality of measured values is determined at different positions of the chain. A plurality of length values is determined from the plurality of measured values and a position of the segments of the chain is determined. The length values are assigned to the segments of the chain, with the length of the segments of the chain being smaller than the length of the chain.

Apparatus and method for determining the wear condition of a chain

In a method for determining the elongation of segments of a chain of a chain drive during operation, a plurality of measured values is determined at different positions of the chain. A plurality of length values is determined from the plurality of measured values and the length values are assigned to the segments of the chain, with the length of the segments of the chain being smaller than the length of the chain.

An actuator includes first and second structural units arranged independently of one another. An engagement means is arranged in the first structural unit. A drive motor is in driving relationship to the engagement means and arranged in the first structural unit. An anti-backbend chain is in engagement with the engagement means, and a chain depot is arranged in the second structural unit.

Actuator comprising anti-backbend chain

The invention relates to an actuator with an anti-backbend chain, a drive motor, and a worm which can be driven by the drive motor and which comprises a helical groove. The anti-backbend chain has engagement means and is guided along the worm, and the chain is in engagement with the worm by means of the engagement means and the helical groove to drive the anti-backbend chain. Such an actuator should have a more compact design and should optionally exhibit less wear. For this purpose, the core diameter of the worm is larger than twice the distance from the motor axis to the motor exterior along which the anti-backbend chain is guided, and the anti-backbend chain is guided at least partly along the drive motor by means of the engagement means.

Actuator with an anti-backbend chain

A chain sensor includes a first magnetic circuit, a device for measuring the magnetic flux density in the first magnetic circuit, and a coil. The magnetic circuit is substantially formed by a magnetically conductive yoke body. The yoke body has a lateral leg, the end of which is disposable in the proximity of a chain. The device for measuring the magnetic flux density is connected to an analysis unit. To determine the elongation of the chain during operation, a partially closed magnetic circuit is formed, a voltage is applied to a coil disposed in the magnetic circuit, an alternating magnetic flux density is generated in the magnetic circuit by the movement of the chain through the partially closed magnetic circuit, the alternating magnetic flux density in the magnetic circuit is detected as a plurality of measured values, and a length value of the chain from the measured values is determined.

A control method for generating a manipulated variable for controlling a hydraulic drive. In this case, account is taken of at least a desired value for the speed of the hydraulic drive, a first parameter, which simulates the response characteristic of the hydraulic drive, and a second parameter, which simulates the internal resistance which the technical process, opposes to the hydraulic drive. It is advantageous that nonlinear dependencies of the hydraulic drive can be taken into account for generating the manipulated variable driving the hydraulic drive. A technically complicated sensor system may be dispensed with. The control method may serve, in particular, the nonlinear control of a plastics injection molding machine.

A modulatable laser diode for high frequencies, such as a tuneable turn guide distributed feedback laser diode, that has a central layer provided for a separate current supply located between a tuning layer and an active layer. The tuning layer has a quantum well structure. A ridge waveguide is provided for the laser diode and the layer sequence is limited to a strip-shaped mesa on the substrate in order to reduce the parasitic capacitances.

A clamping device is used for clamping a pressure plate which is supported on elastic cable holders inside a frame, which clamping device has two wedges whose respective hypotenuses rest on one another, which wedges can move relative to one another and can be pushed between the parts to be spread, and which clamping device has a piston-cylinder unit for moving the wedges. Overall, the clamping device has two piston-cylinder units, arranged side-by-side and parallel, on a support, with wedges which can be moved onto one another.

A laser diode array includes ridges formed in a cover layer forming an upper layer of a semiconductor body, the ridges being provided with separate contacts to produce laser active stripes in an active layer situated between a substrate and the cover layer. The thickness of the cover layer between the ridges is such that lateral coupling is achieved, while the thickness of the cover layer in the region adjoining the outside edges of the outer ridges is small enough so that lateral emission losses are low as the result of quasi-index guidance based on the metal clad ridge waveguide principle. A second embodiment provides wave guidance at the outside edges of the outer ridges by a buried heterostructure principle.
