Auto-iris - the capability of the Autopilot system to hold a constant beam size regardless of the location of the performer. Also known as Auto-size.
Auto-run - the capability of the system to start tracking upon power up.
Beltpack - the device worn by the performer containing the electronics and the battery.
Beltpack element - the transmitting device connected to the beltpack which the Autopilot system tracks.
Beltpack height offset - the ability of the Autopilot system to focus the light at the beltpack element or directly above or below it.
Controller - the rack mount enclosure containing the main hardware and software of the Autopilot II product.
Beltpack channel - the DMX channel which determines whether the light is under manual pan/tilt control or follows a specified beltpack.
Coordinate system - a means of specifying the position of an object in 3 dimensional space via X, Y and Z values. The origin is X=0, Y=0, Z=0.
Dead zone - this is an invisble sphere surrounding the beltpack element inside which the beltpack element can move without the light moving.
DMX map - a table showing which DMX channels are assigned to a light, a control channel, etc.
Fade distance - the distance over which the light will fade out as it approaches the operating boundary.
File - a PC file containing the stage setup (boundaries, light models, etc).
Light - the moving lights used with Autopilot II.
Light calibration procedure - a method of enabling the Autopilot system to determine the X, Y, and Z coordinates and orientation of each light.
Operating area - the space where the lights follow the performer.
Operating boundary - the perimeter of the operating area.
Receiver - the devices mounted above the operating area which receives the ultrasonic signal from each beltpack.
Receiver calibration procedure - a method of constructing the invisible 3 dimensional coordinate system and enabling the Autopilot system to determine the X, Y, and Z coordinates of each receiver.
Temperature sensor - the silver, cylindrical device connected to the controller which measures the air temperature which is used in calculating the speed of (ultrasonic) sound.
Zone - an area, inside the operating
area, where a specified light follows a specified beltpack.
