A Picatinny mounted, left side charging handle system adapted for mounting on AR-15, M-4, or M-16 and similar rifles. The charging handle mounts on the foremost Picatinny mount of the upper receiver and replaces OEM charging handles provided with the rifle. Side mounting overcomes the problem of a shooter's finger being moved from the trigger and/or the shooter's cheek moving from the stock weld so that the shooter's eyes may remain on the intended target. The novel charging handle mounts on the upper receiver and readily accommodates mounting virtually any optical device in addition to the charging handle. The novel charging handle may be mounted to the rifle with no rifle modification required. Rifles may alternately be charged by pulling back a protruding rear portion of the charging handle. The apparatus may readily be transferred between rifles. The rifle equipped with novel charging handle remains fully field strippable without tools.

The present disclosure provides a digital detector apparatus for use with a sensor unit is provided wherein the sensor unit includes an emitter device and a receiver device, the receiver device having a capacitance. The digital detector apparatus comprises at least a first input port, first output port, and a second output port; and an A/D converter circuit wherein an input of the A/D converter circuit is coupled to the first input port for receiving an output of the receiver device; wherein the first output port of the digital detector apparatus is coupled for charging and discharging the capacitance of the receiver device; the second output port of the digital detector apparatus is coupled for driving the emitter device; and the A/D converter circuit derives a sensor output value from the output of the receiver device during a number of charging and discharging cycles. A digital smoke detector and a method of generating an output signal in a digital detector are also provided.

A device for cocking a weapon (11) having an axially movable actuating element (2) that can be coupled to a cocking element (11.1) on the weapon for the purpose of cocking the weapon (11) may include a control device (3) that couples the actuating element (2) to a safety locking element (11.2) on the weapon, whereby the weapon (11) is simultaneously made safe and is armed by actuation of the actuating element.
