Harold Dean Kesling (April 8, 1901 – 1979) was an American orthodontist who is known for developing the tooth positioning appliance called "Positioner". This appliance is used in orthodontics at the end of treatment to allow teeth to settle in occlusion. [1]
The second type of positioner is an analog I/P positioner. Most modern processing units use a 4 to 20 mA DC signal to modulate the control valves. This introduces electronics into the positioner design and requires that the positioner convert the electronic current signal into a pneumatic pressure signal (current-to-pneumatic or I/P).
VBox Communication was established in 2001 and received strategic investment from Optibase (now part of Vitec [1]). [2] [3]On Jan 9, 2002 VBox Communications acquired from BroadLogic (now part of Broadcom [4]) its Satellite Express and DTV product lines, adding DVB core functionality to VBox's IP.

Within the penalty area is another smaller rectangular area called the goal area (colloquially the "six-yard box"), which is delimited by two lines starting on the goal-line 6 yd (5.5 m) from the goalposts and extending 6 yd (5.5 m) into the pitch from the goal-line, and the line joining these. Goal kicks and any free kick by the defending team ...
The fan maintains a constant static pressure in the discharge duct regardless of the position of the VAV box. Therefore, as the box closes, the fan slows down or restricts the amount of air going into the supply duct. As the box opens, the fan speeds up and allows more air flow into the duct, maintaining a constant static pressure. [11]
Some engines, such as GM's Premium V family, use crank position sensors which read a reluctor ring integral to the harmonic balancer. This is a much more accurate method of determining the position of the crankshaft and allows the computer to determine, within a few degrees, the exact position of the crankshaft (and thereby all connected ...
VirtualBox supports both Intel's VT-x and AMD's AMD-V hardware-assisted virtualization. Making use of these facilities, VirtualBox can run each guest VM in its own separate address-space; the guest OS ring 0 code runs on the host at ring 0 in VMX non-root mode rather than in ring 1.
