The system consists of a very thin piece of filter glass placed in front of the image sensor; the area between the filter and the sensor is sealed, so no dust can enter. Whenever the camera is turned on, a piezoelectric driver induces a vibration in the filter glass, shaking dust off. A piece of adhesive located inside the camera traps removed ...
If the mouse attempts to take the bait, the coin is displaced and the glass traps the mouse. [14] Another method of live trapping, the bucket trap , is to make a half-oval shaped tunnel with a toilet paper roll, put bait on one end of the roll, place the roll on a counter or table with the baited end sticking out over the edge, and put a deep ...
James Henry Atkinson (c. 1849–1942) was a British ironmonger from Leeds, Yorkshire who is best known for his 1899 patent of the Little Nipper mousetrap. [1] He is cited by some as the inventor of the classic spring-loaded mousetrap, [2] [3] but this basic style of mousetrap was patented a few years earlier in the United States by William Chauncey Hooker in 1894.
Image of a guillotine-style mousetrap seller in the mid-19th century. In February 1855, Emerson wrote in his journal, under the heading "Common Fame": If a man has good corn or wood, or boards, or pigs, to sell, or can make better chairs or knives, crucibles or church organs, than anybody else, you will find a broad hard-beaten road to his house, though it be in the woods.
More sophisticated versions are electronic i.e. feature a break-wire sensor which detects a drop in voltage. Either way, pulling on the hidden wire triggers detonation. Anti-lifting fuzes — these are frequently screwed into an auxiliary fuze pocket located underneath anti-tank landmines. The act of lifting or shifting the mine releases a ...
The gun-powered mouse trap proved inferior to spring-powered mousetraps descending from William C. Hooker's 1894 patent. However, the 1882 patent has continued to draw interest–including efforts to reconstruct a version of it–due to its unconventional design. [4]
The trap-forming hologram also can specify the mode structure of each trap individually, thereby creating arrays of optical vortices, optical tweezers, and holographic line traps, for example. [55] When implemented with a spatial light modulator , such holographic optical traps also can move objects in three dimensions. [ 56 ]
A camera trap with a passive infrared (PIR) sensor. A camera trap is a camera that is automatically triggered by motion in its vicinity, like the presence of an animal or a human being. It is typically equipped with a motion sensor—usually a passive infrared (PIR) sensor or an active infrared (AIR) sensor using an infrared light beam. [1]
