摘要:
A projector having at least one laser diode which is designed to emit light, having a laser control device which is designed to control the at least one laser diode, having a first controllable resonant mirror which is designed to reflect the light that is emitted by the laser diode, and having a control device which is designed to control the orientation of the first controllable resonant mirror. The control device is further designed to reduce the power supply to the laser diode and to the laser control device in a first configuration of a power-saving mode of the projector, and to further control the orientation of the first controllable resonant mirror at a resonant frequency of the first controllable resonant mirror. Moreover, a corresponding method is described.

A method for ascertaining a gesture performed in the light cone of a projected image which has a plurality of pixels includes: detecting all pixels of the projected image and one or multiple parameter values of the individual pixels; comparing the one or the multiple detected parameter values of the individual pixels with a parameter comparison value; assigning a subset of the pixels to a pixel set as a function of the results of the comparison; and ascertaining a gesture performed in the light cone of the projected image based on the assigned pixel set.

A laser projection device is described for projecting laser beams onto a projection plane, including a controllable multibeam laser diode unit; including a controllable optical deflection unit, which is designed in such a way that laser beams generated by the multibeam laser diode unit are deflected with the aid of the deflection unit; and including a control unit, which is designed in such a way that it controls the deflection unit to move laser beams deflected by the deflection unit onto a projection plane along a scanning line in such a way that different deflected laser beams run in the projection plane on the same scanning line.

A telecommunication device has: a projection unit for projecting image information on a projection surface situated outside the telecommunications device, the image information being projected onto the projection surface (i) with the aid of at least one optical element in a projection beam path for sequentially constructing an image, and (ii) for momentarily spatially limiting the projection relative to the total area of the image information on the projection surface; and a detection unit. During projection a movement of the projection surface, e.g., a displacement or a rotation, takes place relative to the projection unit. The detection unit detects the movement of the projection surface with the aid of a reflection signal passing along a detection beam path, the projection beam path and the detection beam path coinciding at least in the area of the at least one optical element.

A component has at least one MEMS element and at least one cap made of a semiconductor material. The cap, in addition to its mechanical function as a terminus of a cavity and protection of the micromechanical structure, is provided with an electrical functionality. The micromechanical structure of the MEMS element of the component is situated in a cavity between a carrier and the cap, and includes at least one structural element which is deflectable out of the component plane within the cavity. The cap includes at least one section extending over the entire thickness of the cap, which is electrically insulated from the adjoining semiconductor material in such a way that it may be electrically contacted independently from the remaining sections of the cap.

A slide transfer mechanism for a laser scanner device (1) is proposed. The laser scanner device (1) is configured for imaging and/or measuring fluorescent samples which are located in a sample plane (49) on sample slides (8). The laser scanner device (1) comprises a motor-drivable sample table (2) for holding a sample slide (8); a first optical system (53) for providing at least one laser beam (54); a scanner apparatus (72) for deflecting the laser beam (54) toward the sample, wherein the scanner head (50) is configured to be moveable back and forth in a direction of a scanning axis or X axis of a coordinate system. The laser scanner device (1) also comprises at least one detector (61) for detecting an emission beam bundle (59) coming from the sample and a second optical system (58) for forwarding the emission beam bundle (59) to the at least one detector (61). The slide transfer mechanism of the laser scanner device (1) is characterized in that it comprises a motorized transport device (3) that is configured for transferring a sample slide (8) from a storage unit (4) of the laser scanner device (1) to the sample table (2) and back, and in that the sample table (2), for the purpose of transferring sample slides (8), is configured so as to be able to move to immediately before the storage unit (4) for the sample slides (8) or before a loading opening (100) of an additional housing (29).
