...Alarm Clock. When Hunt and crew had a rat sleeping peacefully, they recorded its heartbeats on an electrocardiograph (300-350 beats per min.). Then they squirted it with a beam of silent, invisible, 250,000-volt X rays. In about 12 sec., the rat woke up, sometimes going into a violent "state of alarm." Its heartbeat would speed up too. But if the radiation continued for long, the rat would go to sleep again, like a human grown accustomed to a steady night-time sound...
...Jacobey and colleagues began by giving dogs standardized heart attacks by injecting plastic pellets into their coronaries. Five out of six dogs died. Then they hooked up six other dogs, also given heart attacks, to a small, simple pump that is timed by the electrocardiograph. When the heart contracts, the pump is relaxed and actually withdraws a little blood. When the heart relaxes, the pump gets in its "beat"' and forces blood through the aorta into the coronary arteries. After two hours on the pump, five out of these six dogs lived...
...more sophisticated model, developed in San Francisco by Dr. George A. Harkins (now in Boston) and Engineer Mogens L. Bramson, works on gas pressure and is hooked up to an electrocardiograph. It works like the Oregon machine until a faint natural heartbeat is detected. Then it automatically synchronizes itself, through the ECG, with the human pump, and works with it, never against...
First "clothes" applied were four electrocardiograph sensors glued to his chest. Then came a respirometer (to measure breathing) taped to his neck and a rectal thermometer to measure deep body temperature. Wires from all these instruments were gathered at a metal plug that would be fitted later into the space suit. After all wires and instruments were checked, Shepard donned long underwear with built-in spongy pads to aid air circulation. Then he was helped into his 30-lb. space suit made of aluminized nylon outside and rubberized nylon inside. It was a tight squeeze. Before all Zippers, straps...
...room; low-priced ship-to-shore radios, direction finders and fathometers for small boats; citizen band radios at $99 a pair; transistorized electronic organs for the home, priced from $700 to $1.500; a miniature telemetering system between doctor and patient that will broadcast the patient's electrocardiograph, brain wave or other biological signals whenever the doctor tunes in at a few miles' range...
