A hell-fire trigger is a device that allows a semi-automatic firearm to fire at an increased rate. The hell-fire clamps to the trigger guard behind the trigger and presses a "finger" against the back of the trigger to increase the force that returns the trigger to its forward position, effectively decreasing the time required for the trigger to reset, allowing for a faster follow-up shot.
The preinstalled trigger of a particular firearm is replaced by the forced reset trigger's assembly. Typically, only one shot is fired per single function of the trigger. However, in the U.S., the ATF considers some forced reset triggers to be machineguns under the National Firearms Act . [ 1 ]
A binary trigger (or pull and release trigger) is a type of device that allows a semi-automatic firearm to fire at an increased rate. A binary trigger works by firing one shot upon pulling the trigger and then firing a subsequent shot upon release of the trigger. Binary triggers are installed through modification of the fire-control group.
The original tripod-mounted rubber band rotary gun, patented by Surefire Products, was featured on the Gadget Show on UK television in March 2007 and January 2010. A twelve-barrel rotary gun using twelve-shot repeater mechanisms can fire 144 rubber bands automatically. It is fired by manually rotating a crank handle and pulling a firing trigger.
In robotics, a manipulator is a device used to manipulate materials without direct physical contact by the operator. The applications were originally for dealing with radioactive or biohazardous materials, using robotic arms , or they were used in inaccessible places.
Mexico has been preparing possible retaliatory tariffs on imports from the U.S., ranging from 5% to 20%, on pork, cheese, fresh produce, manufactured steel and aluminum, according to sources ...
Serial manipulators are the most common industrial robots and they are designed as a series of links connected by motor-actuated joints that extend from a base to an end-effector. Often they have an anthropomorphic arm structure described as having a "shoulder", an "elbow", and a "wrist".
A manipulator can move an object with up to 6 degrees of freedom (DoF), determined by 3 translation 3T and 3 rotation 3R coordinates for full 3T3R mobility. However, when a manipulation task requires less than 6 DoF, the use of lower mobility manipulators, with fewer than 6 DoF, may bring advantages in terms of simpler architecture, easier control, faster motion and lower cost.
