Jog dial

A jog dial, jog wheel, shuttle dial, or shuttle wheel is a type of knob, ring, wheel, or dial which allows the user to shuttle or jog through audio or video media. It is commonly found on models of CD players which are made for disc jockeys, and on professional video equipment such as video tape recorders. More recently, they are found on handheld PDAs, and as the scroll wheel on computer mice. "Jog" refers to going at a very slow speed, whereas "shuttle" refers to a very fast speed.

There are two basic types of wheels. One type has no stops and can be spun the entire way around, because it is a relative rotary encoder. This type depends on tracking the actual motion of the dial: the faster it spins forward or back, the faster it fast-forwards or rewinds. Once the dial stops moving, the media continues playing or remains paused at that point. Another type has stops on either side, and often has three or so speeds which depend on how far it is turned. Once the wheel is released, it springs back to the middle position and the media pauses or begins playing again.

Dial (band)

Dial is a progressive rock band based in the Netherlands.

History

Dial was founded in late 2003 by Liselotte Hegt, Rommert van der Meer and Kristoffer Gildenlöw. Early on, the band was pure a hobby but after Kristoffer's departure from Swedish prog metal band Pain of Salvation in early 2006, the band headed towards a more serious destiny.

In summer 2006, the band went to Austria to record their debut album Synchronized together with producer Devon Graves (of Deadsoul Tribe and Psychotic Waltz). This album was released in May 2007 through Prog Rock Records (US).

Rotary dial

A rotary dial is a component of a telephone or a telephone switchboard that implements a signaling technology in telecommunications known as pulse dialing. It is used when initiating a telephone call to transmit the destination telephone number to a telephone exchange.

On the rotary dial, the digits are arranged in a circular layout so that a finger wheel may be rotated with one finger from the position of each digit to a fixed stop position, implemented by the finger stop, which is a mechanical barrier to prevent further rotation. When released at the finger stop, the wheel returns to its home position by spring action at a speed regulated by a governor device. During this return rotation, the dial interrupts the direct electrical current of the telephone line (local loop) a specific number of times for each digit and thereby generates electrical pulses which the telephone exchange decodes into each dialed digit. Each of the ten digits are encoded in sequences of up to ten pulses. For this reason, the method is sometimes called decadic dialling.

Jog (dislocations)

Jog describes the turns of a dislocation line inside a crystal structure. A dislocation line is rarely uniformly straight as in the figure, often containing many curves and/or steps to facilitate movement through the crystal in incremental amounts, rather than shifting the entire line at once. One of these step types is a jog, the other is a kink. However, both are typically referred to as jogs, which can be a source of confusion.

Segments of dislocation line that have a component of their sense vector normal to the glide plane are termed jogs. See image for the definitions of the sense vector and the glide plane. Segments of dislocation line that do not leave the original glide plane are termed kinks.

Jogs are often very immobile compared to kinks, and require diffusion of crystallographic defects like vacancies or interstitial atoms to climb. They are not capable of glide (movement in the glide plane) because the direction of motion is in the plane normal direction, not on the plane itself as with kinks.

Yamaha Jog

The Jog is a scooter produced by the Yamaha Motor Company since 1983, and was introduced in North America in 1986. It continued production in North America after 3 style changes and model designations (CE50, CG50 and CY50) until 2001. The Jog has continued production elsewhere in the world and uses the current CV50 designation.

The Jog CE50

For the first generation Jog, produced from 1986 to 1987, was actually part of the Riva family and in many areas was initially known as the Riva Jog. It was powered by an air-cooled two-stroke reed valve 49 cc (3.0 cu in) vertical Minarelli single-cylinder engine producing with 4.5 hp (3.4 kW) and 4.3 lb·ft (5.8 N·m) of torque. The top speed was 35–38 mph (56–61 km/h). For 1986 it came in red or yellow, and in 1987 it was red or blue.

The Jog CG50

In 1988 the Yamaha Jog was released after being completely restyled and carried the designation CG50. It was powered by the same vertical Minarelli engine as the prior CE50 Jog but had been tuned just a bit to put the top speed in at 40 mph (64 km/h). Color combinations included white/purple, red, and black. The CG50 was sold in North America from 1988 to 1991.
