In the United States , a destructive device is a firearm or explosive device regulated by the National Firearms Act of 1934. Examples of destructive devices include grenade s, and firearms with a bore over one half of an inch, including some semi automatic shotgun s. While current federal laws allow destructive devices, some states have banned them from transfer to civilians. In states where banned, only law enforcement officers and military personnel are allowed to possess them. All National Firearms Act firearms including destructive devices, must be registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives , who then closely monitor use, transport, and storage of the items. The definition of a destructive device is found in UnitedStatesCode 26 5845 f . The definition reads as follows 1 any explosive , Incendiary device incendiary , or poison gas, A bomb , B grenade , C rocket having a propellant charge of more than 4 ounces, D missile having an explosive charge of more than 1 4 ounce, E Land mine mine or F similar device. 2 Any weapon by whatever name known which will, or which may be readily converted to, expel a projectile by the action of an explosive or other propellant, the barrel or barrels of which have a bore of more than one half inch in diameter .50 inches or 12.7mm , except a shotgun or shotgun shell which the Secretary finds is generally recognized as particularly ... for use in converting any device into a destructive device as defined in subparagraphs 1 and 2 and from which a destructive device may be readily assembled.

Orphan date February 2009 Device Bay was a standard jointly developed by Compaq , Intel and Microsoft in 1997, as a simple way to add, remove, and share hardware devices. Originally intended to be introduced in the second half of 1998, Device Bay was never finalized and has long since been abandoned. The official website disappeared in mid 2001. Making use of new technologies at the time, such as USB and Firewire, Device Bay was intended to make adding and removing devices from the PC easier, through the use of plug n play. It allowed peripherals such as hard drives, CD DVD ROM drives, audio devices, and modems, to be added to the PC without having to open the case or even turn the PC off. Devices could also be removed from the PC while it was still turned on this could also be done through software in the operating system. Another advantage of Device Bay was that it allowed certain devices to be swapped between a desktop and laptop computer.

File Brannock uspat1725334 fig1.png thumb right Brannock Device from US Patent,1 724,244 The Brannock Device is a measuring instrument invented by Charles F. Brannock for measuring a person s shoe size . The son of a shoe industry entrepreneur, Brannock attended Syracuse University , New York , United States U.S.A. where he became a member of the Delta Kappa Epsilon Fraternity. Brannock spent two years developing a simple means of measuring the length, width and arc length of the human foot . He eventually improved on the wooden RITZ Stick, the industry standard of the day, and patented his first prototype in 1926. The device has both left and right heel cups and is rotated through 180 degrees to measure the second foot. Brannock later formed the Brannock Device Company to manufacture and sell the product, and headed the company until 1992 when he died at age 89. Today, the Brannock Device is an international standard of the footwear industry, and the Smithsonian Institution houses samples of some of the first Brannock Devices. The Brannock Device Company was headquartered in Syracuse, New York , until shortly after Charles Brannock s death. Salvatore Leonardi purchased the company from the Brannock Estate in 1993, and moved manufacturing to a small factory in Liverpool, New York . The company continues to manufacture several models of the device for determining the shoe sizes of men, women, and children they also produce specialized models for fitting other types of footwear.

In computing , specifically Unix like operating systems, a raw device is a special kind of block device file that allows accessing a storage device such as a hard drive directly, bypassing the operating system s caches and buffers although the hardware caches might still be used . Applications like a Database management system can use raw devices directly, enabling them to manage how data is cached, rather than deferring this task to the operating system. On FreeBSD, all block devices are in fact raw devices. Support for non raw devices was removed in FreeBSD 4.0 in order to simplify buffer management and increase scalability and performance. On Linux raw devices were deprecated and scheduled for removal at one point, because the O DIRECT flag can be used instead ref http lkml.org lkml 2007 2 16 431 ref . However, later the decision was made to keep raw devices support since some software cannot use the O DIRECT flag ref http lkml.org lkml 2007 5 13 92 ref . Raw devices simply open block devices as if the O DIRECT flag would have been specified. Raw devices are character devices major number 162 .
