摘要:
An improved method of analyzing target analytes in a sample is described. The method is based on creating an approximately homogeneous distribution of light in an anti-resonant guided optical waveguide to improve light-target interaction in a target-containing medium. The light-target interaction can be monitored by many different means to determine characteristics of the target analyte.

A fluidity structure includes a channel, a portion of which can contain fluid. Light can propagate in the portion, such as in response to illumination. The refractive index of material at the portion's boundary can be higher than that of the fluid, and more than approximately 10% of intensity of light propagating longitudinally occurs in the fluid, possibly approximately 90%. An IC can be positioned along the portion, with a set of cells of a photosensor array on the IC sensing photons emanating in response to the propagating light. The light can enter through a light-transmissive component along the channel's boundary, then pass obliquely through a portion of the channel that contains air before passing through a bounding component and obliquely into the portion that can contain fluid. The light can couple to an anti-resonant waveguide mode.

Photons emanating from a channel in a fluidic structure or from moving objects are sensed using a photosensor array in an integrated circuit. The array includes subrange cells that photosense within respective subranges of a photon energy range. For example, the subrange cells can receive photons in their respective subranges from a transmission structure that has laterally varying properties. The photons can be emitted in response to excitation or can be scattered in response to illumination.

A method of forming a semiconductor device includes forming a local strain-inducing structure of a first semiconductor material at a point location within a dielectric layer. The local strain-inducing structure has a prescribed geometry with a surface disposed above a surface of the dielectric layer. A second semiconductor material is formed over the dielectric layer and the local strain inducing structure, wherein formation of a first portion of the second material over the dielectric layer provides a poly crystalline structure of the second material and wherein formation of a second portion of the second material over the local strain-inducing structure provides a single crystalline structure of the second material subject to mechanical strain by the surface of the local strain-inducing structure. The single crystalline structure serves as a strained semiconductor layer of the semiconductor device.

An arrangement for modifying the local intensity of x-ray radiation includes an x-ray filter with a plurality of absorption chambers, which may be filled by a ferrofluid. The absorption chambers are stacked in the x-ray beam direction. The x-ray filter includes a plurality of storage containers in which the ferrofluid may be stored. Each of the absorption chambers is connected to a respective one of the storage containers. The absorption of the x-ray radiation is achieved as a result of individual absorption chambers being filled with the ferrofluid. By filling a different number of absorption chambers, the local intensity of the x-ray radiation may be modified easily, precisely and quickly.

In a method for monitoring the hitch of at least one trailer, which is hitchable to a tow vehicle, the tow vehicle having a steering system with which a steering angle is settable, the following steps are performed: a) detecting yaw oscillations of the tow vehicle over a certain period of time, e.g., 1 second to 3 seconds, at a constant or almost constant steering angle and above a predefinable speed of the tow vehicle without brake intervention, and b) evaluating the detected yaw oscillations for whether the amplitudes of the yaw oscillations do not fall below a predefinable amplitude threshold.
摘要:
Input light, such as from an optical sensor or stimulus-wavelength converter, includes one or more light or dark sub-bands. The input light is transmitted, such as through a transmissive layer or transmission component, to obtain effects due to transmission with lateral variation. A detector can, for example, obtain spectral information or other photon energy information about the sub-bands due to lateral variation. For each light or dark sub-band, a transmission component can, for example, provide a respective light or dark spot, and spot position can be used to obtain spectral information such as absolute wavelength or wavelength change. A photosensing component can sense or detect transmitted light or output photons, such as with a photosensor array or a position-sensitive detector. Circuitry can use photosensed quantities to obtain, e.g. a differential signal or information about time of wavelength change.
