It consists of three or four cam s mounted on a common axle or two adjacent axles, so that pulling on the axle forces the cams to spread farther apart. The SLCD is used by pulling on the trigger a small handle so the cams move together, then inserting it into a crack or pocket in the rock and releasing the trigger to allow the cams to expand. At this point the climbing rope can be attached to a sling climbing equipment sling and carabiner at the end of the stem. A pull on the rope, such as that generated by a climber falling, will cause a properly placed SLCD to convert the pulling force along the stem of the unit into outwards pressure on the rock, generating massive amounts of friction and preventing the removal of the unit from the rock. Because of the large forces which are exerted on the rock when an SLCD is fallen on, it is very important that SLCDs are only placed in solid, strong rock. ref name freedom cite book edition 7 editor Cox, Steven M. and Kris Fulsaas, ed. title Mountaineering The Freedom of the Hills publisher The Mountaineers isbn ... that a load produces a rotational force, the logarithmic cam shape allowed for a single device to fit ....

nofootnotes date January 2011 A relocking device RLD a.k.a. external relocker is an auxiliary locking device intended to be activated during an attempted burglary of a safe or vault. Such a device will keep a safe or vault locked even if the primary lock is defeated. This independent mechanism is designed to maintain the locked state of a safe even if the lock itself is destroyed. This auxiliary locking device usually consists of a spring loaded bolt of some type, held in check by a bracket or cable that is rigged to release the mechanism in a burglary attempt. The device will either block the main boltwork from retracting or block the door from opening. Thermal relocking devices Designed as a defense against torch attacks, these are simply relocking devices equipped with a fusible link designed to melt and release the relocking device if the temperature inside the door exceeds a certain temperature usually 65 C , as would happen in a torch attack. Glass relocking devices A glass relocking device is a piece of glass, usually tempered, placed where it might be expected to break in a burglary attack. It is attached, usually with wires, to one or more spring loaded bolts, which are often randomly located. A drill or torch may break the glass, releasing the bolts.

A PASS device Personal Alert Safety System also known as an ADSU Automatic Distress Signal Unit , is a personal safety device used primarily by firefighter s entering a hazardous Immediately Dangerous to Life and Health IDLH environment such as a burning building, which sounds a loud audible alert to notify others in the area that the firefighter is in distress . The PASS device will automatically activate if the device does not detect motion for a certain short period of time, typically 15 30 seconds, so that the alert will sound if the firefighter is seriously injured or otherwise incapacitated. Some devices use a ball bearing on a track to sense firefighter movement and others utilize an infrared beam against a mirror mounted on a spring. When activating for a lack of motion, the PASS device will typically emit a few seconds of a muted warning that activation is about to occur, so that a firefighter who has simply been motionless for a time but is otherwise safe will be able to move slightly and thus reset the activation timer before a false activation occurs. The PASS device can also be activated manually in an emergency, such as when a firefighter is lost or trapped. While older models of PASS devices required manual arming by firefighters prior to entering a dangerous environment, the current application integrates the PASS device into the self contained breathing apparatus self contained breathing apparatus SCBA worn by firefighters so that it automatically arms when the SCBA air supply is engaged or when the SCBA is removed from its mounting bracket.

A classic example is the centrifugal governor , also known as the James Watt Watt or fly ball governor, which uses weights mounted on spring loaded arms to determine how fast a shaft is spinning, and then uses proportional control to regulate the shaft speed. History Image Gibbs governor.jpg 150px right thumb The Gibbs Governor Centrifugal governor s were used to regulate the distance and pressure between millstone s in windmill s since the 17th century. Early steam engine s employed a purely reciprocating motion, and were used for pumping water an application that could tolerate variations in the working speed. It was not until the Scottish engineer James Watt introduced the rotative steam engine, for driving factory machinery, that a constant operating speed became necessary. Between the years 1775 and 1800, Watt, in partnership with industrialist Matthew Boulton , produced some 500 rotative beam engine s. At the heart of these engines was Watt s self designed conical pendulum governor a set of revolving steel balls attached to a vertical spindle by link arms, where the controlling force consists of the weight of the balls. Building on Watt s design was American engineer Willard Gibbs who in 1872 theoretically analyzed Watt s conical pendulum governor from a mathematical energy balance perspective. During his Graduate school years at Yale University , Gibbs observed that the operation of the device in practice was beset with the disadvantages of sluggishness and a tendency to overcorrect for the changes in speed it was supposed ... back against the spring, partially closing the throttle.
