摘要:
A pulse heating—time of flight mass spectrometric gas elements analyzer, which involves the chemical analysis field of inorganic materials, and comprises of a pulse heating electrode furnace, a sample charging system, a purification device, a time-of-flight mass spectrometer, a signal acquisition and data processing system, and an automatic control system. Said electrode furnace and sample charging system are united as one via upper/lower electrodes and pneumatic cylinders, to form a closed hearth. Said electrode furnace, purification device and time-of-flight mass spectrometer are interconnected through the gas pipelines: the purified inert carrier gas comes into the hearth from its top, carrying out the gas components released from sample fusion, and upon re-purification, comes into the time-of-flight mass spectrometer; said signal acquisition and data processing system is connected to the detector of the said mass spectrometer via signal cables, and on the basis of computation by the data processing module of the relevant computer software, outputs the mass percentages of O, N, H and Ar in the sample. The lower limit of detection can be below 0.01 ppm to 0.1 ppm, and no less than three elements can be measured simultaneously in one analysis cycle.

Systems and methods may provide for obtaining or implementing augmented reality information. A logic architecture may be employed to detect a low acceleration condition with respect to an image capture device. The logic architecture may select data from a video associated with the image capture device in response to the low acceleration condition. The logic architecture may also use the data to obtain augmented reality information for the video. Additionally, the logic architecture may modify the video with the augmented reality information, or may display the video with the augmented reality information.
摘要:
A method and system for device detection in a 2D medical image. In order to account for shape variation of a 3D object in a 2D imaging plane, a hierarchical tree-structured array of trained classifiers is used to detect a 3D object, such as a pigtail catheter in a 2D medical image, such as a fluoroscopic image. The hierarchical tree-structured array of trained classifiers increases a dimensionality of the search space with each hierarchical level, and as the search space is increased, the classification is split into object sub-classes using trained classifiers independently trained for each sub-class.
摘要:
A periodic time-varying model of a guide wire, other device, or vessel is created from higher contrast CINE acquisition. A multivariate curve regression is used for periodic, phase dependent motion modeling. This model is then used to locate or track the guide wire, other device or vessel in lower contrast fluoroscopy images during intervention.

The disclosure provides a data source searching system and a method adapted for the system. The system includes a number of cloud servers which store data. The system acquires creation time of the data in each cloud server in response to a command for searching data source of the data. A time zone of each cloud server is acquired. The system compares all creation time of the data in all cloud servers based on the time zones to determine which creation time of the data is in fact the earliest among all compared cloud servers and regards the cloud server which stores the data whose creation time is the earliest as the data source of the data.
