Silver whiskers growing out of surface-mount resistors Metal whiskering is a phenomenon that occurs in electrical devices when metals form long whisker-like projections over time. Tin whiskers were noticed and documented in the vacuum tube era of electronics early in the 20th century in equipment that used pure, or almost pure, tin solder in ...
This word usage is a metaphor derived from the idea of a dog (animal) biting and holding on, the "dog" name derived from the basic idea of how a dog jaw locks on, by the movement of the jaw, or by the presence of many teeth. In engineering the "dog" device has some special engineering work when making it – it is not a simple part to make as ...
Animals that do not whisk, but have motile whiskers, presumably also gain some advantage from the investment in musculature. Dorothy Souza, in her book Look What Whiskers Can Do [35] reports some whisker movement during prey capture (in cats, in this case): Whiskers bend forward as the cat pounces. Teeth grasp the mouse tightly around its neck.
Tin whiskers, on the other hand, grow from surfaces coated with tin alloys - including many solders, and (as noted in the article) alloys used for component pins. Solder-coated traces on printed circuit boards _are_ close enough together for whiskers grown in-situ to cause shorts.
This sweet pooch has been to hell and back, but has finally found the loving family he deserves. Anubis was found living under cars in Cairo after his muzzle had been cruelly cut off, leaving him ...
The occiput in dog terms is the bump or protuberance clearly seen at the back of the skull in some breeds like the English Setter and Bloodhound. However, in other breeds it is barely perceptible. Myths in dog folklore believed that size of the occipital protuberance was somehow a measure of the dog's sense of smell.
The actress said the metal dog collar she had to wear in 2003's 'Dogville' was "so heavy and hard to get off" Nicole Kidman Will 'Never Forget' Choking on “Dogville” Set with a Metal Dog ...
Dogs have ear mobility that allows them to rapidly pinpoint the exact location of a sound. Eighteen or more muscles can tilt, rotate, raise, or lower a dog's ear. A dog can identify a sound's location much faster than a human can, as well as hear sounds at four times the distance. [41] Dogs can lose their hearing from age or an ear infection. [42]
