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.

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.

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.

The present invention comprises a lens with variable refraction power as well as an optical system for the use as, preferably accommodating, visual aid. The lens is designed as an intraocular lens or as a contact lens. The general idea of the invention is to determine the accommodation requirement from the position of the eyes relative to one another. This is possible, since the accommodation requirement and the eyes' motor activity are closely related. According to a first embodiment, the present invention claims a lens with variable refraction power, which possesses the following components: means for adaptation of the refraction power, especially by a change of the lens' curvature as a reaction to a control signal; at least one position locator; means for detection of the relative position of the position locator to at least another position locator arranged on another lens; means for generation of the control signal for adaptation of the refraction power of the lens to the detected relative position and at least one device for power supply for at least parts of the components of the lens.
摘要:
A circuit arrangement, having a circuit and a computer unit is provided, in which the circuit and the computer unit are connected to one another via multiple lines for transmitting a number of signals which are embodied as information signals. The circuit has a multiplexer for combining signals, the multiplexer being connected to the computer unit via an additional line.
摘要:
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.

The disclosure relates to a self-accommodating lens, which is formed in particular as a contact lens. The lens includes a lens body configured to be placed onto or into an eye of a patient. A plurality of actuators are arranged in a star-shaped manner on the front side of the lens body. The angle to an adjacent lens is determined by detection of a directional radio signal.
