Abstract: A method and a device for detecting the phase of a four-stroke gasoline engine, a gasoline direct injection engine in particular. For reliable phase detection involving relatively little expense during a starting phase, a crankshaft is turned together with at least one piston; ignition is triggered via an ignition coil in at least two successive top dead centers of the piston without a supply of fuel. A primary current or a secondary current, or a primary voltage or a secondary voltage are measured in a measuring period which extends at least over a spark duration after the ignition. From the comparison of the measuring signals of successive ignitions, a conclusion is drawn as to which of the successive top dead centers is an ignition top dead center and which is a charge cycle top dead center.

Abstract: A sensor system includes a sensor which is connected to an analyzer, which powers the sensor and analyzes a measuring signal generated by the sensor using an analyzer circuit. To simplify the interconnection of sensor and analyzer and make different ground-side connection variants possible, the analyzer circuit is situated on the power supply side of the sensor.

Abstract: An injector for implanting a folded intraocular lens with which a folded lens can be inserted into the capsula of the lens of the eye through an opening incision of about 3 mm in the eye. The injector consists of three parts, namely a one-piece body, a pivoting flap which is provided with a folding rib and by which the lens is held in an unfolded state in a first position above the transporting channel and is slid folded into the transporting channel by radial pressure, and a third component, the slider through which the folded lens can be slid forwards in the longitudinal direction and out of the injector into the eye.

Abstract: An intraocular artificial lens for placement in an eye having an interior chamber and a posterior chamber, the intraocular artificial lens having a planar lens body configured to be arrangeable in the posterior chamber of the eye and at least one spirally shaped haptic fastener fixed to the lens body. The haptic fastener includes a posterior chamber portion with a first end connected to the lens body and being configured to extend spirally from a peripheral edge of the lens body so that the posterior chamber portion forms a support segment that is elastically supportable in a posterior chamber angle of the eye, a penetration portion arranged at a second end of the posterior chamber portion so as to curve out of the plane of the lens body so as to be passable through an iridectomy, and an anterior chamber portion connected to the penetration portion so as to be parallel to the plane of the lens body.

Abstract: A signal lamp is disclosed for use in automotive vehicles. The lamp includes a housing, a reflector for producing parallel rays, a lens closing the housing in the direction of light exit and diaphragms mounted behind the lens. The outside of the lens is provided with non-reflecting or weakly reflecting transverse stripes to avoid undesired reflections. In one advantageous embodiment, the diaphragms are positioned only in an upper portion of the lamp.
