  • Patent number: 12294367
    Abstract: A level shifter includes a cross-coupled transistor pair, first through third biased transistor pairs and a differential input pair sequentially coupled in series, and further includes a sub level shifter. The first biased transistor pair is controlled by a first reference voltage. The second biased transistor pair is controlled by a pair of differential control voltages. The third biased transistor pair is controlled by a second reference voltage lower than the first reference voltage. The differential input pair is controlled by a pair of differential input voltages. The sub level shifter generates the differential control voltages according to the differential input voltages and the first and second reference voltages. The differential control voltages are switched between the first and second reference voltages. The level shifter outputs a pair of differential output voltages through inverted and non-inverted output terminals coupled with the second biased transistor pair.

  • Publication number: 20250137446
    Abstract: A peristaltic pump device includes a casing, a flexible tube, and a roller module. The flexible tube is disposed within an accommodating space of the casing and has a curved tube portion. The roller module is rotatably disposed within the accommodating space and surrounded by the flexible tube and includes a holder structure movable relative to the curved tube portion, a roller mechanism rotatably mounted on the holder structure, and an actuating rod. The actuating rod is movable upward and downward relative to the curved tube portion. A protruding structure protrudes laterally from at least one of the holder structure and the actuating rod. When the actuating rod moves downward, the protruding structure interferes with another of the holder structure and the actuating rod for moving the holder structure to make the roller mechanism compress the curved tube portion by a lateral, rotational, or tilted movement of the holder structure.
