Abstract: A conductive yarn pressure sensor is proposed. The pressure sensor may include a porous fiber layer having predetermined cavities formed therein. The pressure sensor may also include a first sensing electrode made of a first conductive yarn formed on one surface of the porous fiber layer, and a second sensing electrode made of a second conductive yarn formed on the other surface of the porous fiber layer. The first sensing electrode or the second sensing electrode may be provided so as to be in contact with each other in the cavities of the porous fiber layer due to external pressure. According to an embodiment, by having conductive yarn in flexible clothing or textile material, pressure can be sensed by effectively responding to deformation due to external pressure.

Abstract: A method for controlling a buck converter is provided. The method includes monitoring an inductor current flowing through an inductor in the buck converter. The method includes controlling the buck converter to operate in a pulse frequency modulation (PFM) mode with intermittent conduction if the inductor current experiences a plurality of cross-zero periods. The method further includes adjusting a power consumption of a component in the buck converter according to the plurality of cross-zero periods of the inductor current, when the buck converter is operating in the PFM mode.

Abstract: A semi-automatic feces shoveling cat litter box, comprises a shell, a cat litter bin, and a feces shoveling component. The shell is arranged on the outer periphery of the cat litter bin, and the middle part of the shell is provided with a first opening for cats to enter into the cat litter bin. One end of the shell is provided with a second opening for the cat litter bin to pass through. Under the action of external force, the shell and the cat litter bin move relatively to each other. The end of the cat litter bin away from the second opening is provided with a waste bin. The feces shoveling component is arranged on the end of the shell near the second opening. One end of the feces shoveling component is hinged to the shell, and another end is provided with a first dentate structure.
