Another Lockheed

creation is this multi-

purpose vehicle

that finds itself at

almost any

where-on

swamps

and

marshlands,

even in

Four rotating lenses of 3 -in. focal length

record

images of

of different

wavelengths

side by side

on 91-

green, red,

and near -infrared filters show up as black -

to the

brightness of

the filtered light.

To the

When

Calling Centers. With all these

electron-

ic aids, tomorrow's soldier

won't

need

worry

too

much about

enemy

attack. But

speeding

information

to command centers

will

call for split -second communications.

To

this end,

Litton

Industries has built

a

microminiature radio

transmitter that

weighs only four pounds,

complete

with bat-

teries. Formally named the "Digital Message

Entry Device,"

it

switch. Instantly, the

digital

message

will

burst

over

the

airwaves to

be

picked

up at a

command center by a standard

receiver.

Each of the 22 numbers

represent a pre-

arranged

message. And

hears

a responsive

he

knows his message has been decoded.

Tiny TV. Though digital messages can-

has

the

Even

The

is believed to

be the
