  • Publication number: 20210317316
    Abstract: The present disclosure relates to a method for preparation of a high temperature-resistant bismuth yellow pigment. The method comprises: mixing an oxide which served as a matrix and dopan with a bismuth source, a vanadium source, or a molybdenum source, and then placing the mixture into a mill for grinding to obtain a precursor; further calcining and crushing the precursor to obtain the high temperature-resistant bismuth yellow pigment powder. The bismuth yellow pigment has a bright color, a b* value greater than 90, a stable performance, and a high heat-resistance above 800° C. The method is environmentally friendly without waste, and reaction conditions are simple. Doping of BiVO4 crystal lattices by incorporation of oxides can be achieved, so that the particle size and distribution of the bismuth yellow pigment can be effectively controlled while the color performance of the bismuth yellow pigment is greatly improved.

  • Patent number: 11119547
    Abstract: An information handling system includes a voltage regulator, a device, and a controller. The voltage regulator provides an output voltage to power on the device. The controller includes a voltage enable sense line. The controller provides a signal to enable the voltage regulator on the voltage enable sense line at a first voltage associated with a first state. The controller also monitors a voltage level on the voltage enable sense line, and determines whether the voltage level of the voltage enable sense line has changed to a second voltage level associated with a second state. In response to the voltage level on the voltage enable sense line changing to the second voltage level, the controller detects that the output voltage is fully turned on and provided to the device.
