Denver door opener Heavy pry bars connected with a hinge, one with an adjustable foot, used for prying open doors. Denver tool (also called TNT tool): A combination axe, sledgehammer, pry tool, ram, and D-handle pull tool used to gain forcible entry to buildings, automobiles, etc. during emergency situations. Detection system See Alarm system.
Wall-mounted electromagnetic door holder securing a door in the open position. An electromagnetic door holder (electromagnetic door holder and release or hold-open device, sometimes informally called a mag hold open or electric doorstop) is a simple electromechanical mechanism which can be used to hold a fire door or security door open until given a signal to release.
A probe tip is an instrument used in scanning probe microscopes (SPMs) to scan the surface of a sample and make nano-scale images of surfaces and structures. The probe tip is mounted on the end of a cantilever and can be as sharp as a single atom .
In 1959, while at a picnic with friends and family, Fraze discovered he had left his "church key" can opener at home, forcing him to use a car bumper to open cans of beer. Fraze decided to create an improved beverage opening method that would eliminate the need for a separate device, leading to his creation of the pull-tab opener.
It consists of a length of tube of around 4 mm to 6 mm in diameter, often made of coiled steel springs, with a push-button on one end.Three metal wires protrude from the other end, each sprung to bend outwards, away from the tube's axis, but with their tips bent inwards to form teeth.
Probe stations have evolved to better manage both wafer level and device testing. An example of this is the VERSA probe system by Micromanipulator. Systems like the VERSA can visualize and probe all size wafers from 50mm, 100mm, 150mm, 200mm, 300mm, and even 450mm. systems like the VERSA can also manage testing individual chips or die as well ...
The matched impedances provide better high-frequency performance than an unmatched passive probe can achieve, but at the expense of the low 500-ohm load offered by the probe tip to the DUT. Parasitic capacitance at the probe tip is very low so, for very high-frequency signals, the Z 0 probe can offer lower loading than any hi-Z probe and even ...
A Luggin capillary (also Luggin probe, Luggin tip, or Luggin-Haber capillary) is a small tube that is used in electrochemistry. The capillary defines a clear sensing point for the reference electrode near the working electrode. [1] [2] This is in contrast to the poorly defined, large reference electrode. [clarification needed]
