Abstract: The present disclosure discloses a method for manufacturing a color Micro LED display chip module, comprising preparing a Micro LED chip on a substrate, grinding and cutting the chip and then flip-bonding same on a driving basal plate, and peeling the substrate from the chip. Through fabricating a quantum dot hole site corresponding to a sub-pixel unit position of a chip on a transparent basal plate and filling a quantum dot light-color converter in the quantum dot hole site and depositing a quantum dot protective layer, a conversion device is fabricated independently on the transparent basal plate. Compared with processing a conversion layer on a substrate layer in the prior art, inverting a full-color quantum dot conversion device and then aligning and bonding same with the integrated monochrome Micro LED module base can improve the fabrication efficiency, eliminate the crosstalk between light and color in full-color Micro LED display.

Abstract: The present disclosure provides a float valve motion detection device, a pot cover assembly and a pressure cooking appliance, the float valve motion detection device comprising: a float valve, a hollow inductance coil and a detection circuit. A valve core of the float valve is made of materials having permeability unequal to that of air. When the valve core is pushed by the pressure in a pot from a first position to a second position, the volume of the valve core in the hollow inductance coil changes, which changes the inductance of the hollow inductance coil. A detection circuit determines the position of the valve core by means of detecting the change in the inductance of the hollow inductance coil so as to determine whether it is safe to uncover at the current time.

Abstract: Techniques related to improving the error floor performance of a bit flipping (BF) decoder are described. In some examples, error floor performance is improved through determining a set of unreliable check nodes (CNs) and using information about the set of unreliable CNs to compute the flipping energies of variable nodes (VNs). In this manner, the flipping energies can be computed more accurately, thereby lowering the error floor. The set of unreliable CNs can be built through applying various criteria, such as criteria relating to the path length to an unsatisfied CN, the degree of a VN in a path to an unsatisfied CN, and/or checksum value. Path length and VN degree can be applied as selection criteria to determine which CNs qualify as members of the set of unreliable CNs. Checksum value can be applied as a trigger condition for building and/or using the set of unreliable CNs.
