Abstract: A method for detecting a particular syndrome based on hemodynamic analysis that includes steps of: obtaining a piece of hemodynamic data representing a hemodynamic waveform; performing moving average (MA) filtering on the hemodynamic waveform to obtain a filtered waveform; determining troughs in order to determine waveform segments of the filtered waveform; determining smoothness of the waveform segments; and determining a relation between the hemodynamic waveform and a particular syndrome based on the smoothness of the waveform segments, and generating a detection result.

Abstract: A method for detecting a location of a segment of a feeding tube is provided. The feeding tube has a proximal end, a hollow tube body and a distal end, and is placed inside the body of a patient. An audio collecting component is placed on a predetermined part of the patient. The method includes steps of pumping air into the proximal end of the feeding tube, collecting sound to obtain audio data by the audio collecting component, performing audio analysis on the audio data, and determining whether a segment of the hollow tube body is at a part inside the body of the patient that corresponds with the location of the audio collecting component based on result of the audio analysis.

Abstract: A disinfecting light fixture including a disinfecting lamp and a detection device is provided. The disinfecting lamp is disposed in an indoor space to emit disinfection light in the indoor space. The detection device is coupled to the disinfecting lamp to turn on or off the disinfecting lamp and includes an emitter, an antenna, a receiver, a signal processor and an actuator. The detection device is configured to detect the condition of the indoor space. In response to a human in the indoor space, the detection device turns off the disinfecting lamp. In response to there being no humans in the indoor space, the detection device turns on the disinfecting lamp.

Abstract: A switching regulator includes a first switch; a second switch coupled between the first switch and ground; an inductor coupled to a common node between the first and second switches; a capacitor coupled between the inductor and ground; a controller receiving a disable signal, and generating first and second control signals respectively for the first and second switches; and a crossing detector comparing an auxiliary voltage at the common node with a negative reference voltage to generate a comparison signal, and generating the disable signal based on the first control signal and the comparison signal. The second control signal switches into an inactive state upon the disable signal indicating a reference-crossing of the auxiliary voltage.
