specially developed negative-slope voltage
based charging method. After the battery is
fully charged, the Tri-Analyzer discharges
the battery. Once the battery capacity is
discharged to one volt per cell, the battery
capacity is displayed in mAh. The battery is
then recharged for use.

optical rather than mechanical techniques to
achieve image stabilization. Besides provid¬

helicopters.
Gyrozoom fits most 2A-inch
ENG/EFP cameras, replacing the standard
lens. It weighs less than eight pounds. Since
a standard lens typically weighs about four
to five pounds, the added weight is minimal.
Gyrozoom has been used by
broadcasters around the world for

news

and

sports coverage that has to be shot from
unstable

platforms such as helicopters, air¬
planes, boats, and motor vehicles.
In sports coverage and tele¬
production, Gyrozoom has meant that
events could be televised in new ways. In
ESPN's 1987 Americas Cup coverage in
Australia, for example - generally consid¬
ered the finest coverage of sailboat racing in
history - Gyrozoom was used from both
aircraft and boats to provide unique footage.
