  • Patent number: 11939625
    Abstract: A method and a sensor for detecting L-cystine are disclosed. The method is implemented by assembling a sodium 3,3?-dithiodipropane sulfonate (SPS) membrane on a surface of Au membrane layer of an Au electrode and using an extended gate of field effect transistor (FET) and in-situ signal amplification of the FET to detect L-cystine sensitively. The polyanion of the SPS membrane adsorbs and binds a positively charged target L-cystine through electrostatic interaction, thus forming an electric double layer structure to generate a membrane potential identifying a monovalent organic ammonium ion. The sensor includes the FET, wherein a gate-extended gold electrode is arranged on the FET, and the SPS membrane is assembled on the surface of the Au membrane layer of the gate-extended gold electrode. The sensor has an excellent Nernst response to L-cystine.

  • Publication number: 20240097483
    Abstract: Carrier signal generators are provided. The carrier signal generator includes a master processing module and a plurality of slave processing modules. Each slave processing module is used to control a corresponding one of universal power units of the UPS. The slave processing modules output, according to a synchronously received reference signal, control signals to control the universal power units to receive power from the mains or a rechargeable battery. When the mains is normal, each slave processing module synchronously generates a three-phase rectification control signal to rectify and output power from the mains. When the mains is abnormal, each slave processing module generates a first DC-DC control signal independently of the reference signal output by the master processing module, so as to convert and output power from the rechargeable battery. The carrier signal generator has improved compatibility and improved current conversion quality and is low cost.
