blink A signal sent by a WhereTag to the RTLS system. A blink may

contain 1 to 8 sub-blinks.

coverage area The area in which a WhereTag will be pinged by a WherePort IV

signal.

dual WherePort IV Two WherePort IVs on a bracket, oriented at 90 degrees to each

other.

guaranteed WP capture area The part of the WherePort IV field where a tag will be pinged.

WP health tag A WhereTag mounted to a WherePort IV to indicate if the

WherePort IV is operating correctly.

WP field The magnetic field produced by the WherePort IV. It is not the

same as the coverage area.

guaranteed WP release area The point beyond which it is certain that a tag will not be pinged.

locked A tag may be locked by a WherePort IV. A locked tag is invisible

to the RTLS system. This tag must be paired with a WherePort IV

that unlocks the tag.

Master In a group of phased WherePort IVs, one must be set as the master.

The phase setting for the master is 0.

orientation Magnetic coils have an orientation. The relationship between the

orientation of the pick up coil in the WhereTag and the transmit coil

in the WherePort IV affects the range of the WherePort IV.

phase WherePort IV setting required when uncertainty areas of coverage

overlap between two or more WherePort IVs. The possible phase

settings are 0, 90, 180, and 270.

ping What a WherePort IV does to a WhereTag when the tag is in the

field.

sequence WherePort IVs linked together which transmit at intervals set by the

master WherePort IV in the sequence.
