摘要:
A method for a quantitative detection of a linear movement or rotary movement. The method includes the steps of emitting radiation from at least two light emitters in a pulsed mode at a same clock frequency or different clock frequencies and detecting the radiation from the two light emitters by a detection device. It furthermore includes the steps of increasingly shadowing the radiations by a movable grid device or separating signals originating from different light emitters by an evaluation circuit coupled to said detection device.
摘要:
An optical device for quantitative detection of linear or rotary movements, in which light beams from two light emitters pass through a grid disk which images the movement and has translucent areas and opaque areas. A single photo receiver is also provided in which the transmitted light strikes the photo receiver. The light emitters are actuated in a pulsed mode. The pulses are separated from one another in an evaluation circuit that is coupled to the photo receiver.

A radiation emitter component, in particular an infrared emitter component with a conventional light-emitting diode housing, includes two electrode connections, one of which has a well-shaped reflector. The housing has an optically transparent, electrically non-conducting encapsulation material. A semiconductor laser chip is fastened in a well-shaped reflector of the light-emitting diode housing. The semiconductor laser chip has a quantum well structure, in particular with a strained layer structure, for example MOVPE epitaxial layers with a layer sequence GaAlAs-InGaAs-GaAlAs. A diffusor material can be inserted into the optically transparent, electrically non-conducting material of the light-emitting diode housing. The diffusor material is constructed or inserted with regard to type and concentration in such a way that in connection with the semiconductor laser chip encapsulated in the light-emitting diode housing, a radiation characteristic curve or an increase of an effective emission surface is produced that is comparable to that of a conventional infrared light-emitting diode.

In order to accommodate the ammunition (7) in an ammunition magazine (1) in a space- and mass-saving manner without an external drive, and to subsequently remove the ammunition quickly from the magazine, the individual ammunition bodies (7) are disposed, with the aid of holders (10), on the chain links (8, 9) of a rigid-backed chain (6) (ammunition chain) seated to be displaced in two rails (3, 4). In such an arrangement, the ammunition (7) can be removed quickly from the magazine (1) through the withdrawal of the chain (6) and the pivoting of the individual chain links (8, 9) toward the rear side (15) of the chain (6), and stowed again when the chain (6) is pushed back into the magazine frame.

A motor vehicle headlight element is specified which has at least one light-emitting diode and at least one control apparatus. The control apparatus is suitable for processing a signal which is dependent on a measurement variable and for applying a current, corresponding to the signal, to the light-emitting diode. The control apparatus and the light-emitting diode are arranged on a common mount.

The optoelectronic semiconductor component has an optoelectronic semiconductor chip disposed on a chip carrier with an approximately planar chip carrier surface. The semiconductor chip is fastened with predetermined alignment of its optical axis. A plastic base part supports the chip carrier. The semiconductor chip is electrically conductively connected to at least two electrode terminals routed through the base part, and a lens is disposed above the semiconductor chip on top of the base part. The lens is formed with an independently configured cap produced from plastic material. The cap is mechanically form-locked to a support of the base part. When the cap is placed onto the base part, a holder of the cap and the support engage with one another. The holder and the support are configured such that when the cap is placed onto the base part, the two parts are automatically positioned with respect to one another in such a way that the optical axes of the lens and of the semiconductor chip coincide.

A carrier vehicle (1) for a tube weapon (2) having a resiliently arranged undercarriage (3) and a support arrangement (5) which in the combat-ready position is arranged between the vehicle (1) and the ground (4), with the support arrangement comprising at least one support (6). To avoid manual readjustment of the support arrangements (5), even when firing from a position with a soft underground, the supports (6), which are disposed at the tail of the vehicle (1), are arranged so as to be slidable in the direction of their longitudinal axes (7) via a positioning motor (15). The positioning motor (15) is connected to an electronic control device (16) which actuates the positioning motor (15) in a manner such that the support (6) is pressed against the ground (4) with a definable force before a shot is fired and compensation is provided for the gap (18) which occurs between the support (6) and the ground (4) after a shot has been fired because of the resilient yielding and rebounding of the undercarriage (3).
