Abstract: A computer-assisted method for quantitative characterization and treatment of ventricular fibrillation includes preprocessing a time series of an atrial fibrillation signal obtained from a patient, segmenting the time series of the AF signal into activation segments by the computer system, obtaining local activation waveforms (LAW) from the activation segments, determining degrees of similarity between the LAWs, and identifying one or more critical regions in the patient's atria if the LAWs have degrees of similarity exceeding a first threshold value.

Abstract: A method implemented through an electronic system for processing a sequential data to identify possible peak points is disclosed. The method defines a decayed threshold function and partition the sequential data into a plurality of segments by grouping each data point with surrounding data points into one of the segments. After that, a plurality of weighted segments are derived through weighting the surrounding data points by the decayed threshold function in each of the segments, and the peak points are identified through corresponding weighted segment.

Abstract: An electronic device includes a body, a first pivot element, a second pivot element, and an image capturing module. The first pivot element is pivoted to the body and used for rotating along a first axis as a rotating axis. The second pivot element is pivoted to the first pivot element and used for rotating along a second axis as a rotating axis. The first axis is substantially perpendicular to the second axis. The image capturing module is configured in the second pivot element and electrically connected to the body for capturing an image outside the second pivot element.

Abstract: A computer casing including a main casing, a cover, a fluid cylinder and a first connecting element is provided. The main casing has a front panel. The fluid cylinder with a rod is disposed in the main casing. The rod is suitable for moving between a first position and a second position. The first connecting element has a first end, a second end and a pivoted portion. The first end connects to the rod, and the second end connects to the cover. The pivoted portion is located between the first end and the second end, and the first connecting element is pivotally connected to the main casing via the pivoted portion. When the rod locates at the first position, the cover is substantially meeting the front panel. When the rod locates at the second position, the cover is far away from the front panel.

Abstract: A non-metallic article includes a non-metallic substrate, a base coating, a metallic decorative coating, and a light-transmitting protective coating. The base coating includes a prime layer applied on the non-metallic substrate. The metallic decorative coating is deposited on the base coating, and includes a multi-color layer having a multi-color appearance. The multi-color layer is made of a cermet material produced by sputtering from a metal target using a gas mixture containing oxygen, nitrogen and hydrocarbon. The light-transmitting protective coating is applied on the metallic decorative coating.

Abstract: An intravenous injection device for detecting the position of a vein of an examinee includes a pedestal comprising a housing, a pulse ultrasound probe installed in front of the housing, and a microprocessor installed in the housing wherein the pulse ultrasound probe includes an oscillator for emitting a pulse ultrasonic signal toward the examinee along the direction of the housing and a sensor for receiving ultrasonic signals reflected by the examinee and converting the reflected signals into electric signals to output to the microprocessor, a propeller for moving the pedestal along the direction of the pulse ultrasonic signals, and a syringe connected to and conveyed by the propeller to move along the direction of the pulse ultrasonic signals.

Abstract: A system is disclosed which functions in two distinct yet interrelated modes. In a modeling mode the system provides a customized multi-body model, wherein problem specific functions are created for analysis of complex real-world machines. A preprocessor facilitates the multi-body model description and a symbolic generator then generates model specific code in FORTRAN of some other convenient computer language. The model code is portable and self contained. In a numerical simulation mode actual multi-body system data are combined with the model code, whereby the system is manageable by a user not necessarily familiar with the modeling techniques, but familiar with the multi-body system modeled. Simulation operations by the system produce outputs descriptive of the multi-body system without redundancy, which outputs may then be utilized by the user through a post processor to compute further quantities of interest and to apply visualization to interpret results.

Abstract: An apparatus for refining hot metal to steel including a converter provided in the bottom thereof with imbedded concentric double-tube injectors for introducing oxygen enveloped by a shielding gas into the interior of the steel bath to oxidize impurities, and also including in the upper side wall thereof, water-cooled lance-burners for injecting oxygen and fuel into the freeboard space (area above the bath) of the converter to burn the combustibles of the bath gas. The coolant means for the said lance-burners may be introduced through the trunnions of the converter and piped by a distribution system to each of the lances. Alternatively, an overhead water-cooled lance may be used to enter the vessel in the vertical position through the mouth opening.
