摘要:
An optoelectronic device for emitting electromagnetic radiation with a controllable emission intensity comprises, at least one optoelectronic component (100) which is adapted for generating, in operation, electromagnetic radiation (90), a first electronic element (200) and a second electronic element (300). The first electronic element (200) is adapted for controlling the emission intensity of the electromagnetic radiation (90), generated by the optoelectronic component (100), within a first intensity range, and the second electronic element (300) is adapted for controlling the emission intensity of the electromagnetic radiation (90), generated by the optoelectronic component (100), within a second intensity range.

A shunt system includes a first catheter and a second catheter, each having a proximal end and a distal end, and at least one opening adjacent to its distal end. A proximal end of a drainage catheter is in fluid communication with the proximal end of the first catheter and the proximal end of the second catheter. A first one-way valve is disposed in fluid communication with the first catheter between its proximal end and its at least one opening. The first one-way valve effectively blocks fluid flow from the proximal end to the at least one opening. A second one-way valve is disposed in fluid communication with the second catheter between its proximal end and its at least one opening. The second one-way valve effectively blocks fluid flow from the proximal end to the at least one opening.

摘要:
A light beam is deflected by refraction and total internal reflection through a first prism, and projected through a first lens onto a scene that is to be scanned. The prism rotates, which varies the deflection angle and scans the beam across the scene along a scan line. Preferably, the successive side surfaces of the prism have different tilt angles relative to the rotation axis, so as to respectively deflect the beam in different deflection planes which cause successive scan lines of the beam across the scene. The emitted beam gives rise to a reflected beam from the scene, which is received through a second lens and deflected onto a photodetector through a second prism congruent to and rotating synchronously with the first prism. This apparatus is suitable as a laser scanning device for an object recognition system or a spacing distance regulation system of a motor vehicle.
