  • Publication number: 20200338564
    Abstract: A nucleic acid loading device, including a housing, a carrying module, a motion module, a liquid circuit module and a control module. The motion module includes a support platform, first and second driving mechanisms, and a carrying member. The liquid circuit module is configured to control a reagent to flow into and out of a reactor. The control module is connected with the motion module and the liquid circuit module, and the control module is configured to control the first and second driving mechanisms, the liquid circuit module and the temperature control unit. A first face of a semiconductor cooler heats or refrigerates during operation, providing heat for an accommodating seat through a heat conducting body such that the reactor can be at different ambient temperatures. The cooperation between the motion and liquid circuit modules may achieve automation and industrialization of loading a sample into the reactor.

  • Patent number: 10467749
    Abstract: The present disclosure provides a method and a system for processing an image. The method includes: an image pre-processing step, including analyzing an image input to be processed so as to obtain a first image; and a spot detecting step, including analyzing the first image so as to compute a spot determining threshold; analyzing the first image so as to acquire a candidate pixel spot, and judging whether the candidate pixel spot is the spot according to the spot determining threshold; computing a sub-pixel center coordinate of the spot and an intensity value of the sub-pixel center coordinate if yes; and discarding the candidate pixel spot if no. According to the method, the image is denoised in the image pre-processing step, such that a calculation in the spot detecting step may be reduced. In addition, the accuracy of determining the image spot may be improved.

  • Publication number: 20150012668
    Abstract: A method of extending a network utilizing the Digital Living Network Alliance (DLNA) protocol includes providing a first DLNA network being a local area network (LAN) conforming to the DLNA protocol and a second DLNA network being a LAN conforming to the DLNA protocol. Communication is established between the first DLNA network and the second DLNA network, the first DLNA network and the second DLNA network communicating with each other over a wide area network (WAN). Multimedia content is then output from a digital media server (DMS) of the first DLNA network to a digital media renderer (DMR) or a digital media player (DMP) of the second DLNA network.
