  • Patent number: 11935950
    Abstract: A device includes a first buried layer over a substrate, a second buried layer over the first buried layer, a first well over the first buried layer and the second buried layer, a first high voltage well, a second high voltage well and a third high voltage well extending through the first well, wherein the second high voltage well is between the first high voltage well and the third high voltage well, a first drain/source region in the first high voltage well, a first gate electrode over the first well, a second drain/source region in the second high voltage well and a first isolation region in the second high voltage well, and between the second drain/source region and the first gate electrode, wherein a bottom of the first isolation region is lower than a bottom of the second drain/source region.

  • Publication number: 20120000453
    Abstract: A firing device of a side-handle baton includes first and second shaft portions, a magazine portion, a trigger housing, a gas chamber portion, and a nozzle portion. Pressure from a CO2 cartridge in the second shaft portion enters and accumulates in the gas chamber portion to push a nozzle. Once a pushbutton of the magazine portion is pressed, ball-shaped bullets in the magazine portion fall into a bore of the first shaft portion, and the magazine portion pushes a trigger in the trigger housing, thus driving a sear to release the nozzle. When a piston rod in the nozzle is freed, the pressure in the gas chamber portion is discharged to fire the bullets. A recoil spring then pushes the nozzle portion back to re-seal the gas chamber portion, allowing pressure to accumulate again in the gas chamber portion, and the sear to retain the nozzle until the next shot.
