  • PROCESSING METHOD FOR PREVENTING ELECTROMAGNETIC INDUCTION WHEN MAIN SYSTEM AND STANDBY SYSTEM OF SAFETY DRIVE UNIT CO-DRIVE RELAY
    Publication number: 20240177953
    Abstract: A processing method for preventing electromagnetic induction when a main system and a standby system of a safety drive unit co-drive a relay. The method includes the following steps: periodically acquiring and detecting a drive command; detecting a port state of an output port of a safety drive unit when the drive command changes; performing a corresponding processing operation according to the port state of the output port; and repeating the foregoing steps.

  • Quantum-dot-in-perovskite solids
    Patent number: 10181538
    Abstract: The present disclosure provides a composite material of a pre-formed crystalline or polycrystalline semiconductor particles embedded in a crystalline or polycrystalline perovskite matrix material. The pre-formed crystalline or polycrystalline semiconductor particles and and crystalline or polycrystalline perovskite being selected so that any lattice mismatch between the two lattices does not exceed about 10%. The pre-formed crystalline or polycrystalline semiconductor particles and said crystalline or polycrystalline perovskite matrix material have lattice planes that are substantially aligned.
