  • Publication number: 20230263402
    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.

  • Publication number: 20230218268
    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.

  • Patent number: 7631457
    Abstract: A plant potting includes a base, a magnet mounted in the base and connected to an electric cord, a damper mounted on the magnet, a vibration absorber mounted in the base and located above the damper, a vibrator protruding outwardly from the base and connected to the vibration absorber, a vibration receiver having a lower end connected to the vibrator, a pin holder mounted on an upper end of the vibration receiver, and a plant mounted on the pin holder. Thus, the stems, the flowers and the leaves of the plant function as a medium to transmit the sound wave from the sound so as to output a sound wave in a different sound transmitting way, thereby enhancing the sounding effect of the sound.

  • Publication number: 20060208364
    Abstract: The present invention provides an LED device with a flip chip structure. The LED device comprises an insulating substrate, an LED flip chip, a molding compound, a first conductive element, and a second conductive element. The LED flip chip is electrically connected to the connection pads on the insulating substrate via the two conductive elements. The P-type and N-type electrodes are connected to the P-type and N-type electrodes layers, respectively. The invention need not require a conventional wire bonding process. It not only increases the yield rate of the product but also makes the product more compact.

  • Patent number: 7034763
    Abstract: A slot antenna includes a substrate with a metal ground plate on one side thereof and a plurality of rectangular slots are etched in an inner periphery of the ground plate. An opening is defined in one side of the ground plate and a metal feedline is located on the substrate and located close to the opening. The feedline includes a plurality of sub-sections extending within the slot and at least two matching stubs are formed on the feedline and a sub-ground plate is connected to the ground plate and located in the slot. A plurality of metal floating stubs are attached to the rear side of the substrate. When viewing from the front side of the substrate, the floating stubs are connected across the ground plate and at least one of the matching stubs. The antenna is miniaturized and includes dual-frequency operation.
