45 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.

People old and young
enjoy waxing nostalgic about and learning some of the history of early electronics. Electronics World was published
from May 1959 through December 1971.

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 the room.
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 inches/sec.
