years from now, state-of-the-art reports we read of today will seem
as primitive as some of these projects that appeared in the March 1967
edition of Electronics World. As compared to some of the stories from
1950s - 1960s era, these are notably closer to today's efforts because
by then the transistor and some integrated circuits were commonplace.

Recent Developments in Electronics
Landing System. An Air Force twin-jet trainer is shown
making an accurate approach over a portable ground station during technical
evaluation at Wright Patterson Air Force Base. When interrogated, the
ground unit provides range and range rate as well as conventional glide
path and localizer information to enable the pilot to remain in full
command during approach and landing. The system is being developed by
Honeywell to meet pressing military requirements for an effective all-weather
landing system in remote combat areas, The system operates on the C
band (5100 MHz) and has a range of 10 nautical miles. Four foldable
flat-plate antenna arrays are used along with an omnidirectional antenna,
control box, and optical bore-sight, all mounted on a tripod. It can
be set up and aligned by one man in five minutes. Power is supplied
by a motor generator, with standby 28-volt batteries. The present prototype
weight is 55 pounds but this can be reduced.
Computer-Generated Vocal-Tract Model. Accurate
synthetic speech is now being produced with the aid of a controllable,
computer-generated model of the vocal tract developed at Bell Labs.
The model, based on information stored in a computer, is actually a
geometric description of vocal-tract areas as they are shaped to produce
various sounds. When synthesizing speech, a researcher can see an outline
of the vocal tract displayed on an oscilloscope and at the same time,
hear the sound which corresponds to the displayed shape, By operating
switches and turning knobs at a computer console, the researcher can
change shape and sound simultaneously. Thus, synthetic speech is improved.
TV Camera. A revolutionary tubeless TV camera is being
demonstrated here by RCA Laboratories technician, prior to its delivery
to the U.S. Air Force Avionics Laboratory, sponsor of the development.
The device is described as a first step toward a new era of personal
TV communication systems, with eventual application in military, space,
medical, industrial, and home functions. The camera employs arrays of
132,000 thin-film elements deposited on four glass slides only one-inch
square to perform functions similar to those of a pickup tube and picture-processing
elements in a standard TV camera. Contained in the lower portion of
the device as shown here is a miniature transistorized transmitter that
broadcasts picture signals to a special receiver that is located across
Applications Technology Satellite. This is the
new 790-lb satellite that was launched from Cape Kennedy early in December,
This satellite, the ATS-1, is expected to bring practical benefits to
mankind from space technology. It has already been placed in a synchronous
orbit at the intersection of the Equator and the International Date
Line. From this point it has relayed conversations between a ground
flight controller in the U.S. to a number of commercial and government
aircraft flying over the Pacific and the United States. It has also
photographed weather conditions and relayed color-TV signals. Five ATS
satellites are being built by Hughes.
Radio-Range Antenna System. Resembling a giant mushroom
ring, these antennas guide jet aircraft in rugged mountains near Ruedesheim,
Germany. Previous systems were afflicted with dangerous errors due to
reflections of the radio waves from the craggy mountain peaks. The antenna
system, developed by Standard Elektrik Lorenz, ITT subsidiary, is employed
in a doppler v.h.f. omnidirectional radio range. The pattern of the
new VOR antenna is identical with that of the standard system and aircraft
equipment need not be modified.
CCTV Weather Briefing System. Weathervision-a
closed-circuit television system for briefing pilots on weather and
flight conditions-is to be used by our Strategic Air Command and Tactical
Air Command in the U.S. and Europe. The closed-circuit camera scans
information displayed on the console, then relays the picture to monitors
in briefing rooms distant from the central control point. Two-way audio
hookup permits conversation between briefing officer and pilots. Some
72 such systems are being installed at 67 bases under a $3 million contract
awarded to Canoga Electronics.
Fiber-Optic CRT Oscillograph. A new recording oscillograph
which makes use of a special fiberoptic cathode-ray tube to achieve
unprecedented direct printout writing speeds is shown here. The measured
signal, also monitored by the small scope at the upper right, is recorded
on 6-in-wide photosensitive paper that passes over the face of the tube
during operation. The instrument, introduced by Honeywell, will measure
and record high-frequency analog data at up to one million hertz, and
has a data print-out capability nearly 100 times faster than any other
direct-write system on the market. Writing speed is more than a million
