The term "Rube Goldberg" was being used in print to describe elaborate contraptions by 1928, [2] and appeared in the Random House Dictionary of the English Language in 1966 meaning "having a fantastically complicated improvised appearance", or "deviously complex and impractical". [3]
An image trigger initiates the capture of single or multiple frames of a digital camera by analysing the signals of its sensor. For capturing and analysing of fast moving objects (e.g. as in quality control of production lines) modern high speed cameras are frequently used. Typically the initiation of an image-series starts as soon as the ...
This allows for an increased rate of fire. However, the shooter must still manually pull the trigger each time it resets for any subsequent shot to be fired. An image of a forced reset trigger from ATF’s Ammunition Technology Division: Technical Bulletin 22-01. Forced reset triggers are installed through replacement of the trigger control group.
The ratio of the trigger rate to the event rate is referred to as the selectivity of the trigger. For example, the Large Hadron Collider (LHC) has an event rate of 40 MHz (4·10 7 Hz), and the Higgs boson is expected to be produced there at a rate of roughly 1 Hz. The LHC detectors can manage to permanently store about one thousand events per ...
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.
Template matching [1] is a technique in digital image processing for finding small parts of an image which match a template image. It can be used for quality control in manufacturing, [2] navigation of mobile robots, [3] or edge detection in images.
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.
To change this template's initial visibility, the |state= parameter may be used: {{Extreme Makeover: Home Edition | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Extreme Makeover: Home Edition | state = expanded}} will show the template expanded, i.e. fully visible.
