Abstract: Designs and methods are provided for an adjustable rifle stand. In one embodiment the rifle stand includes a three legged support with a moveable head for holding the rifle at a first support location on the rifle forward of the trigger such that the rifle can pivot about the first support location. The rifle stand also includes a rear brace with two extendable legs and a head that holds the rifle at a second support location on the rifle behind the trigger, wherein the lower ends of the legs of the rear brace are pivotally connected to two of the legs of the three legged support. The legs of the rear brace may be extended or contracted by unlocking a leg extension lock in each leg.

Abstract: A pistol has a disconnector for disconnecting a trigger bar from a sear to allow the sear to reset and engage and hold a hammer in a cocked position. Motion of a slide causes rotation of the disconnector through interaction between a cam surface on the slide and a cam follower on the disconnector. A contact surface on the disconnector engages the trigger bar upon rotation of the disconnector and moves the trigger bar out of engagement with the sear. A biasing spring resets the sear into engagement with the hammer which is rotated into the cocked position by motion of the slide.

Abstract: A multi-group transmission of a vehicle having a motor connected to an input shaft of the transmission, via a starting element, and the transmission comprises a splitter group, a main group and a main transmission shaft, on the drive output side. A powershift unit can couple the input shaft to the main transmission shaft for engaging an intermediate gear during a gearshift. The powershift unit and a shifting device for engaging gear constants of the splitter group are an integrated unit. During operating the transmission, with the starting element at least partly engaged during intermediate gear engagement, the powershift unit operates in a slipping mode and supports torque of the motor at the main transmission shaft while rotation of the motor is synchronized with a target gear. After which, an original gear is disengaged while free from load, the target gear is engaged when synchronized, and the intermediate gear is again disengaged.

Rotation of the wheel member moves the sight housing laterally between the opposed sides of the base.

Abstract: A combined flashlight and munition deploying device in which light sources are arranged around a munition-loadable crown of the device so that illumination is emitted in the same direction that the munition is deployed. The flashlight may be operated in a strobe mode. A common trigger is used to first operate the strobe and then to fire the munition. A toggle mechanism serves to cock the firing pin as the crown is being opened for loading a cartridge. An extendable battery compartment may be included, which also serves as an extendable handle. The device may be configured for many different types of less-than-lethal munitions.

Abstract: A sight system is provided which may be selectively used in a variety of different ways. In one example, the sight system may be positioned on a rifle to provide a rifle sight system. In this example, the sight system may be positioned on the rifle barrel a substantial distance away from a user's eye. Advantageously, such an implementation may permit a user to effectively sight the rifle without compromising situational awareness. In another example, the sight system may be used to provide a telescopic sight with a reticle (e.g., a dot, crosshair, mark, or other appropriate shape) superimposed on an image (e.g., a zoomed or non-zoomed image) displayed from a camera. In another example, the sight system may be used to provide an occluded sight in which a camera and/or display of the sight system is disabled. As a result, a reticle may be displayed over an opaque background.
