  • DIRECT CURRENT (DC) TRANSFORMER ERROR DETECTION APPARATUS FOR PULSATING HARMONIC SIGNAL
    Publication number: 20240103097
    Abstract: The present disclosure provides a direct current (DC) transformer error detection apparatus for a pulsating harmonic signal, including a DC and pulsating harmonic current output module and an external detected input module, where the DC and pulsating harmonic current output module outputs a DC and a DC superimposed pulsating harmonic current to an internal sampling circuit and a self-calibrated standard resistor array; and the internal sampling circuit converts the input DC and the input DC superimposed pulsating harmonic current into a voltage signal, and sends the voltage signal to an analog-to-digital (AD) sampling and measurement component through a front-end conditioning circuit and a detected input channel. The DC transformer error detection apparatus can complete self-calibration for measurement of the DC and the pulsating harmonic signal on a test site.

  • Fluorine-containing triazolopyridine, and manufacturing method, pharmaceutical composition, and application thereof
    Patent number: 10800776
    Abstract: A fluorine-containing triazolopyridine represented by formula (I) and a racemate, R-stereoisomer, S-stereoisomer, pharmaceutically acceptable salt, or mixture thereof are described. The triazolopyridine can be used as a positive allosteric modulator of an mGluR2, and is highly selective in activating the mGluR2, exerting no activation or very limited activation of other homologous metabotropic glutamate receptor. The triazolopyridine can thus be used to prepare a product for treating an mGluR2-related disease, such as a central nervous system disease or neurological disease.
