摘要： A converter includes a switching stage including first and second primary transistors, a resonant stage connected to the switching stage, a transformer including a primary winding connected to the resonant stage, a rectifying stage connected to a secondary winding of the transformer and including first and second synchronous rectifiers, and a controller. The controller is configured and/or programmed to operate in a steady-state mode in which an output voltage of the converter is regulated by varying a switching frequency of the first and second primary transistors and of the first and second synchronous rectifiers and a synchronous-rectification control mode in which the output voltage is regulated when an output-voltage overshoot is detected by switching the first and second primary transistors and the first and second synchronous rectifiers at a fixed switching frequency and by varying a duty cycle of the first and second synchronous rectifiers.

摘要： A transformer part (200) including an isolation core casing for a power converter is provided. The transformer part (200) includes a primary winding (202), a secondary winding (204), a magnetic core, a cover (208) and a cup (210). The cover and cup are joined and sealed together to form core casing (212). The primary winding is wound directly on the magnetic core and the magnetic core is sealed within the core casing. The secondary winding is wound around the core casing such that the primary and secondary winding are electrically isolated from each other by a solid insulation barrier provided by the core casing. This means that there is no increase in creepage or clearance path between the two windings, which allows for miniaturization of the transformer part without compromising on safety and converter performance due to leakage inductance.

摘要： The present invention relates to a method and a system for providing temporal information on a subject. The method comprises obtaining a ballistocardiologic signal of the subject with an accelerometer and processing the ballistocardiologic signal to obtain at least a beat-to-beat time (TB2B) signal and a stroke volume (SV) signal. A filtered TB2B signal and a filtered SV signal are provided by filtering the respective signal tore move erroneous values not caused by heart beats. The method further comprises calculating a true HR signal from the filtered TB2B signal and calculating a true SV signal and a stroke volume variability (SVV) signal from the filtered SV signal. The true HR signal is filtered to detect abnormal heart beats and to separate them from normal heart beats,white the true SV and SVV signals are used as parameters to facilitate separation of the abnormal and normal heart beats. If abnormal heartbeats are detected, type of arrhythmia related to the detected abnormal heart beats is identified and temporal information on occurrence and type of the identified arrhythmia is provided to a user.

摘要： The present invention relates to an elongated rapid exchange catheter configured to measure fractional flow reserve of a patient. The catheter comprises a shaft and a distal portion coupled to a distal end of the shaft. The distal portion comprises a lumen configured for inserting a guide wire, and an entry via in a side wall of the lumen for inserting the guide wire into the lumen. The entry via is disposed closer to the proximal end of the distal portion than the distal end of the distal portion. The catheter further comprises plurality of sensing devices comprising at least one distal sensing device disposed at the distal portion and a proximal sensing device. The at least one distal sensing device and the proximal sensing device are disposed at a predefined distance from each other along the longitudinal dimension of the catheter. The proximal sensing device is disposed on the proximal side of the entry via.

摘要： An integrated resistor-capacitor (RC) structure (400) is disclosed. The integrated RC structure includes a vertical capacitor (302, 402, 306) and a resistive element (308, 310) disposed above the capacitor. The integrated RC structure uses a low ohmic substrate (302) to ensure a good ground return path for the capacitor. Further, a resistivity of the substrate is configured such that a top plate (306) of the capacitor provides a reference ground above a predefined frequency. The impedance of the resistive element (308, 310) is matched, relative to the reference ground, to a predetermined resistance. As such, the resistance of the resistive element (308, 310) can be controlled to provide an impedance controlled RC structure over a range of operating frequencies.

摘要： An apparatus includes a substrate (102) and a connector (110) mounted on or to the substrate. The connector is configured to be physically coupled to an external component. The apparatus also includes a first electrical path (108) electrically coupling one or more circuit components (104) to the connector. The apparatus further includes a second electrical path (114) electrically coupling the connector to a terminal pad (118). The second electrical path is physically separate from the first electrical path, and the second electrical path is electrically coupled to the first electrical path by the connector. The terminal pad may be configured to receive, over the second electrical path, a signal provided from the one or more circuit components to the connector over the first electrical path. A presence of the signal from the one or more circuit components at the terminal pad may be indicative of a proper electrical connection between the connector and the one or more circuit components.
