摘要:
A control unit having an oscillator for a processor is described, the control unit storing a temporary absence of oscillation of the oscillator in a first error memory, if oscillation begins again after the absence.

A hybrid vehicle has an internal combustion engine and an electric engine. A drive arrangement for the vehicle has a crankshaft-side clutch part rigidly connected to a crankshaft of the internal combustion engine, and the crankshaft-side clutch part may be coupled to a drive train shaft-side clutch part via a clutch. The clutch part on the drive train shaft side is mechanically connected to a drive train shaft via at least one element for torsional vibration isolation. The drive train shaft is configured at least partially as a rotor of the electric engine. The crankshaft-side clutch part, the clutch and the drive train shaft-side clutch part form at least one part of the primary mass of a dual-mass flywheel. The drive train shaft forms at least one part of the secondary mass of the dual-mass flywheel.

Uterine cervical cancer Computer-Aided-Diagnosis (CAD) according to this invention consists of a core processing system that automatically analyses data acquired from the uterine cervix and provides tissue and patient diagnosis, as well as adequacy of the examination. The data can include, but is not limited to, color still images or video, reflectance and fluorescence multi-spectral or hyper-spectral imagery, coherent optical tomography imagery, and impedance measurements, taken with and without the use of contrast agents like 3-5% acetic acid, Lugol's iodine, or 5-aminolevulinic acid. The core processing system is based on an open, modular, and feature-based architecture, designed for multi-data, multi-sensor, and multi-feature fusion. The core processing system can be embedded in different CAD system realizations. For example: A CAD system for cervical cancer screening could in a very simple version consist of a hand-held device that only acquires one digital RGB image of the uterine cervix after application of 3-5% acetic acid and provides automatically a patient diagnosis. A CAD system used as a colposcopy adjunct could provide all functions that are related to colposcopy and that can be provided by a computer, from automation of the clinical workflow to automated patient diagnosis and treatment recommendation.
摘要:
A method of automated image calibration that corrects for non-uniform illumination and calibrates color that is simple, fast, automated, accurate and reliable. A gray balance algorithm is applied to correct for non-uniform illumination and a color calibration algorithm is then applied to calibrate the human subject data. The system has been applied in multiple clinical sites with different instruments.
摘要:
The image registration systems and methods according to this invention register reflectance and fluorescence hyperspectral imagery and provide the spatial image transformation between the reflectance and fluorescence hyperspectral imagery. A reflectance image is embedded into the fluorescence hyperspectral imagery and thereby resolves the resemblance problem of reflectance and fluorescence hyperspectral imagery. The reflectance image is embedded into the fluorescence hyperspectral imagery using (1) light from a narrow-band source embedded in Ultraviolet (UV) excitation light, (2) second order diffracted light, and/or (3) Ultraviolet (UV) excitation light reflectance. Resembling reflectance images are calculated from the reflectance hyperspectral imagery and the embedded reflectance image in the fluorescence hyperspectral imagery. The two respective reflectance images are pre-processed to maximize the resemblance between them. Image registration algorithms use the two pre-processed reflectance images and calculate the spatial image transformation that allows to map the spatial coordinates from the reflectance to the fluorescence hyperspectral imagery (and vice versa).
摘要:
Methods for cell-based tissue analysis utilize modern trends in digital microscopy to obtain, process, calibrate, and analyze digital images of tissue sections to quantify cell-based data for improved histological analysis. Using data from multiple images of a common tissue section, or data from images of multiple tissue sections, additional degrees of freedom are realized and the resulting analysis provides added depth to histological analysis of tissue samples. With computerized analytical methods, speed and accuracy of histological analysis is greatly improved.

摘要:
An electromagnetic actuator for operating a driven component includes first and second electromagnets having respective first and second pole faces oriented toward one another and defining a space therebetween; an armature disposed between the electromagnets and movable back and forth between the first and second pole faces in a direction of motion; a driving component attached to the armature for moving therewith as a unitary structure; and a resetting spring unit attached solely to the driving component or the driven component and exerting forces opposing movements of the armature caused by electromagnetic forces generated by the electromagnets. The resetting spring unit is in a relaxed state when the armature is in a mid position between the first and second pole faces and is in an armed state upon movement of the armature from the mid position in either direction. A mechanism connects the driving component with the driven component for effecting a transmission of moving forces from the driving component to the driven component to cause displacements of the driven component as a function of displacements of the armature and the driving component.
