  • Publication number: 20190247192
    Abstract: A prosthetic mitral annuloplasty ring includes a wire, an adjustment member for changing a length of the wire and a jacketing annulus for adjusting a radial dimension of the mitral valve annuloplasty ring. The jacketing annulus is sleeved over the wire and forms, together with the adjustment member, a shape matching that of a native mitral valve annulus. After the prosthetic mitral annuloplasty ring is implanted by suturing in a conventional surgical procedure and the patient's heart starts to beat again, the adjustment member can be connected to the delivery device and the wire length therein can be adjusted by a rotating operation of the delivery device so that the mitral valve annuloplasty ring will be expanded or contracted until the prosthetic mitral annuloplasty ring perfectly fits the native mitral valve annulus in shape, effectively avoiding the problem of incomplete mitral leaflet coaptation.

  • Patent number: 10383122
    Abstract: The techniques described herein relate to methods, apparatus, and computer readable media configured to decode modulated data. A modulated signal is received. A format of the modulated signal is determined, wherein the format can include a first format comprising a first type of modulated signal, or a second format comprising the first type of modulated signal and a second type of modulated signal that is different than the first type. The modulated signal is decoded by determining a frequency shift amount based on the format of the modulated signal, shifting a frequency band of the first type of modulated signal from an original position to a shifted position, thereby shifting a center frequency of the first type of modulated signal by the frequency shift amount, and filtering, based on the format of the modulated signal, signals outside of the frequency band of the shifted first type of modulated signal.

  • Publication number: 20190243781
    Abstract: Examples herein describe techniques for providing a customizable direct memory access (DMA) interface which can permit user logic to change or control how DMA read and writes are performed. In one example, a DMA engine may be hardened (e.g., include circuitry formed from a semiconductor material) which prevents the DMA engine from being reconfigured like programmable logic. Instead of changing the DMA engine, the user logic can change or customize the DMA interface between the user logic and the DMA engine. In this way, the manner in which the DMA engine performs DMA write and reads can be changed by the user logic. In one example, the DMA engine includes a bypass mode of operation where descriptors associated with DMA queues are passed through the DMA engine and to the user logic.

  • Patent number: 10352873
    Abstract: An industrial visual stethoscope system and a detecting method are provided. The system has a base, a workpiece support, a single-color lighting device, a camera module, a rotating device, and an analyzing device. When the single-color light irradiates the workpiece, if the single-color light irradiates into the crack which is relatively deep and narrow, the single-color light is rarely to be reflected out of the crack. But if the single-color light irradiates into the scar, the single-color light is reflected out of the scar due to the specular reflection. During the relative rotation, when the reflected light enters the camera module in parallel, the energy of the light is concentrated, causing overexposure and forming obvious white light. Thus, the analyzing device can identify the recess is a scar formed by hit rather than a crack formed by heat.

  • Patent number: 10351888
    Abstract: The invention discloses a high-efficiency synthesis method of difructose anhydride III. The method comprises the following steps: firstly converting sucrose into inulin by using inulosucrase without separating polysaccharide, and then converting inulin by using inulin fructotransferase to synthesize the functional disaccharide difructose anhydride III. The method has the advantages of simple process and high efficiency, and a conversion rate of synthesizing inulin into difructose anhydride III can reach 40%-54%. In order to obtain purer difructose anhydride III, yeast is utilized to remove small molecule monosaccharides in a reaction solution, and the finally obtained purer difructose anhydride III can be easily separated and purified. Thus, the method has broad market application prospects.
