    摘要: An optical scanning device is provided. The optical scanning device an excitation light source that is operable to illuminate the object to be scanned. An image detector is operable to detect excited emission rays through illumination of the object to be scanned by the excitation light source and imaging optics that dictate a focal distance. The image detector detects a scan image of the emission radiation of the object to be scanned with the highest level of image sharpness if the focal distance is maintained. A control device includes a distance sensor through which a distance between an optical scanning device and the object to be scanned can be measured, wherein maintenance of the focal distance as the function of the measured distance can be checked by the control device.

    摘要: A patient monitoring and intervention system, comprises an interface for receiving data representing multiple different parameters from multiple different sensors, comprising sensors in a patient bed and attached to a patient including, a heart rate sensor, a respiration sensor and a pressure sensor indicating bed pressure points. A learning processor determines a normal range for a set of the different received patient parameters for the patient by recording the patient parameter values over a time period and analyzing the recorded parameter values to determine their range. A data processor determines if the set of different received patient parameters exceeds the determined normal range and in response to this determination and in response to the type of parameters in the set and medical record information of the patient, initiates adjustment of a patient bed and at least one of, (a) changes medication administered to a patient and (b) alerts a worker of the patient parameter change.

    摘要: A method produces a radioactively marked carboxylate, at least one precursor molecule of the carboxylate being prepared in a solvent including a conductive salt. Radioactively marked carbon dioxide is fed into the solvent. The precursor molecule is electrochemically reacted with the radioactively marked carbon dioxide to form the radioactively marked carboxylate. The radioactively marked carbon dioxide is completely dissolved in the solvent when the precursor molecule is reacted. The radioactively marked carbon dioxide is used for electrochemically synthesizing a radioactively marked carboxylate, the carbon dioxide being completely dissolved in a solvent during synthesis. A microstructure is used for electrochemically synthesizing the radioactively marked carboxylate, radioactively marked carbon dioxide being reacted.

    摘要: In a method of 3D object detection, a learning procedure is used for feature selection from a feature set based on an annotated image-volume database, generating a set of selected features. A classifier is built using a classification scheme to distinguish between an object location and a non-object location and using the set of selected features. The classifier is applied at a candidate volume to determine whether the candidate volume contains an object of interest.
