摘要： A pixel for detecting incident radiation (In) over a large area with high sensitivity and low power consumption. The pixel comprises a semiconductor substrate (1), covered by a thin insulating layer (2), on top of which a dendritic or arborescent gate structure (3) is arranged. The dendritic gate (3) is electrically connected at two or more contacts (C1, C2) with voltage sources, leading to the flow of a current and a position-dependent potential distribution in the gate (3). Due to the use of arborescent structures and various materials (31, 32), the pixel can be optimized for a certain application, in particular in terms of the electric field distribution, the RC time constant, the power consumption and the spectral sensitivity. Due to its compact size, the photo sensor can be arranged in linear or two-dimensional manner for the realization of line and area sensors.

摘要： The present invention refers, inter alia, to pixel circuits. The pixel circuit according to embodiments of the invention may include a photo-sensitive device having charge storage capability connected to a sense node. The pixel circuit may further include an inverting amplifier which is able to amplify a voltage from the sense node to a voltage on an output node of the amplifier, when being operated in open-loop configuration; and a reset switch being able to connect the input and output nodes of the inverting amplifier and thus to reset the inverting amplifier to an operating point providing high open loop gain by temporarily establishing negative feedback. Moreover, the pixel circuit may include a low-pass filter at the output node of the inverting amplifier for limiting the signal frequencies passing to the readout node to those frequencies that contain useful signal information. Additional and alternative embodiments are specified and claimed.

摘要： A compressor includes a casing defining a generally cylindrical flow passage, a rotor carrying at least one set of rotor blades, at least one set of stator blades, and anti-stall casing treatment. The casing treatment includes an annular recess in the casing for removing low momentum flow adjacent the tips of the rotor blades, and returning the flow to the generally cylindrical flow passage upstream of the point of removal. A plurality of curved guide vanes are located within the annular recess so as to define an annular inlet downstream of the vanes and/or an annular outlet upstream of the vanes. Each guide vane projects radially inwardly from the casing towards a free end which is exposed at or near the mouth of the recess to define a series of curved channels within the recess adjacent the annular inlet and/or the annular outlet.

摘要： The pixel for use in an image sensor comprises a low-doped semiconductor substrate (A). On the substrate (A), an arrangement of a plurality of floating areas e.g., floating gates (FG2-FG6), is provided. Neighboring floating gates are electrically isolated from each other yet capacitively coupled to each other. By applying a voltage (V2-V1) to two contact areas (FG1, FG7), a lateral steplike electric field is generated. Photogenerated charge carriers move along the electric-field lines to the point of highest potential energy, where a floating diffusion (D) accumulate the photocharges. The charges accumulated in the various pixels are sequentially read out with a suitable circuit known from image-sensor literature, such as a source follower or a charge amplifier with row and column select mechanisms. The pixel of offers at the same time a large sensing area, a high photocharge-detection sensitivity and a high response speed without any static current consumption.

摘要： A device and method for spatially resolved photodetection and demodulation of temporally modulated electromagnetic waves makes it possible to measure phase, amplitude and offset of a temporally modulated, spatially coded radiation field. A micro-optical element (41) spatially averages a portion (30) of the scene and equally distributes the averaged intensity on two photo sites (51.1.51.2) close to each other. Adjacent to each of these photo sites (51.1) are two storage areas (54.1, 54.2) into which charge from the photo site can be moved quickly (with a speed of several MHz to several tens or even hundreds of MHz) and accumulated essentially free of noise. This is possible by employing the charge-coupled device (CCD) principle. The device combines a high optical fill factor, insensitivity to offset errors, high sensitivity even with little light, simultaneous data acquisition, small pixel size, and maximum efficiency in use of available signal photons for sinusoidal as well as pulsed radiation signals. The device and method may be used in a time-of-flight (TOF) range imaging system without moving parts, offering 2D or 3D range data.

摘要： In the imaging pyrometer, at least three types of pixels (L, S, V) for sensing electromagnetic radiation in at least three different spectral ranges are arranged in a mosaic pattern. In a neighborhood, there are two types of pixels with relatively narrow spectral sensitivity ranges in the infrared (IR), a first one (L) for sensing longer IR wavelengths and the other one (S) for shorter IR wavelengths. Additionally, there is a third pixel type (V) present for receiving electromagnetic radiation in a broader band such as the visible part of the electromagnetic spectrum. This is preferably realized by placing a mosaic filter pattern directly on pixels of an appropriate optoelectronic image sensor, for example by evaporation and photolithographic definition. The pyrometer makes it possible to measure two images of a scene simultaneously and in perfect geometric registration: a reliable temperature map, based on the two-wavelength pyrometric measurement technique, and a high-resolution picture of the scene, for example in the visible spectral range. The dynamic range for the temperature map measurement and the simultaneous picture acquisition are be increased compared to the prior art, so that both images are acquired under favorable signal-to-noise conditions, and the measurable temperature range between about 350° C. and several 1000° C. is accessible without additional neutral density filters or aperture stops.
