摘要:
An arrangement for determining the position of a surgical microscope uses signal transmitters and signal receivers. Light emitting diodes that emit coded light signals and light receptors for receiving the coded light signals are arranged in various locations in space. Reflectors having narrow-bond reflection characteristics are arranged on the microscope so that the light reflected can be identified.
摘要:
The invention is directed to a surgical microscope in which, to determine the distance between the microscope (8, 13) and the object (22), the travel time of a beam of light (57c) emanating from the microscope and reflected by the object is determined. The travel time is determined by phase measurement or by interference matching. In the case of direct phase measurement, modulated light is used. In the case of interference matching, partly coherent light is used. In order to ensure high accuracy over wide measurement range, the two measurement methods are preferably used in combination.

Recording media for recording information "bits" in response to activation of a laser beam, the media including a recording layer adjacent a "soft pad" layer above and/or below (e.g., a vacuum-evaporated reconstituted fluoropolymer), especially as a "soft pad overcoat". A "hard cap" is overlaid on such a "soft pad" overcoat (e.g., a radiation-cured acrylic) as an outer protective sealing coat. The soft pad may be rendered under the recording layer as a spacer layer.

An optical data storage system is contemplated, one employing a data-modulated writing laser beam and a nonerasing reading laser beam of predetermined wavelength.Improved optical media for such systems are described, these characterized by multiple layers whose optical characteristics and thickness are chosen to accommodate a prescribed writing and reading energy and wavelength and so provide an "anti-friction" condition for unrecorded portions of the medium and a relatively higher reflectivity for recorded portions. A preferred optical medium includes a highly reflective aluminum layer, a relatively transparent polymer spacer layer overlying the reflective layer, and an optical absorber (recording) layer overlying the spacer layer.Overcoating structure is specified in some detail; e.g., as a "soft pad" layer (e.g., fluoropolymer) on the absorber, with a "Hard" layer (e.g., radiation-cured acrylic) laid over the "soft pad" as an outer protective overcoat. Also, the "spacer" may be rendered as such a "soft pad".

One embodiment covers an apparatus for generating a transmission signal. The apparatus may include a signal generator that generates a first signal with a first frequency spectrum comprising a carrier frequency; a power control unit that provides a power information signal which represents a signal level of the transmission signal residing at the carrier frequency; a first signal shaper for noise-shaping the first signal based on the power information signal to form a second signal which has a noise component in at least one frequency range remote from the carrier frequency, the noise component of the second signal being from one or more signal components associated with the carrier frequency; and a signal output that provides the second signal in the form of a transmission signal.

One embodiment of the present invention relates to a modulation system having a phase locked loop and an adaptive control. The phased lock loop is configured to receive an input signal and an adaptive signal. The input signal is an unmodulated signal, such as a phase component or phase signal. The phase locked loop is also configured to provide an error signal and an output signal. The error signal indicates one or more modulation errors. The output signal is a modulated version of the input signal that has been corrected using the adaptive signal to mitigate the one or more modulation errors.
摘要:
A novel type of dye systems comprises a selection of 10H-indolo[1,2-a]indole compounds (henceforth abbreviated as IO compounds) and (5H,7H)-indolo[1,2-a]quinoline compounds (henceforth abbreviated as IQ compounds) showing a solvatochromic effect and exhibiting strong fluorescence in a variety of materials such as polypropylene, polyethylene, oils, various solvents, emulsions. Also disclosed are various methods how the IO/IQ compounds can be administered, especially how they can be produced and administered in situ from a precursor, responding to external stimuli such as enzyme activity, temperature and so forth. The response of a precursor to external stimuli can also be used to determine the presence or absence of such stimuli.

A micromechanical component, in particular a micromechanical sensor having a carrier substrate and having a cap substrate, and a manufacturing method are provided. The carrier substrate and the cap substrate are joined together with the aid of a eutectic bond connection or by a metallic solder connection or a glass solder connection (e.g., glass frit), in an edge area of the carrier substrate and the cap substrate. The connection of the carrier substrate and the cap substrate is established with the aid of connecting areas, and a stop trench or a stop protrusion or both a stop trench and a stop protrusion are situated within the edge areas in the bordering areas.
摘要:
A method is described for manufacturing a micromechanical component. The method includes providing a first substrate, forming a first connecting structure on the first substrate, and forming a microstructure on the first substrate after forming the first connecting structure. The microstructure has at least one movable functional element. The method further includes providing a second substrate having a second connecting structure, and joining the first and second substrates by carrying out a bonding process, the first and second connecting structures being joined to form a common connecting structure, and a sealed cavity being formed in the region of the microstructure. The method provides that the first connecting structure takes the form of a buried connecting structure extending up to an upper surface of the first substrate. Also described is a related micromechanical component.
