A new transducer has been developed that will measure pressure over a wide range by sensing the damping of a vibrating diaphragm immersed in the gas whose pressure is being measured. It is capable of measuring pressures from approximately 10−5 to 2

A new diode‐quad transducer bridge circuit has been developed which features: (1) a high output that is independent of excitation frequency and waveform; (2) a fractional capacitance (ΔC/Co) resolution of 4.4 × 10−8 at a bandwidth of 10–30 Hz

The transverse motion of a tensioned string driven parametrically by a moving end support is examined both analytically and experimentally. The conditions required to linearize the equations of motion for vibrations over a large‐amplitude range at

A simple model of communications capability projected for the mid-1970s is formulated. The spectral dependence of the future state of the art is examined in terms of antennas, noise, diffraction effects, etc. The model suggests that the frequency spe

The results of space experiments designed to determine the intensity and energy distribution of the solar plasma have been somewhat ambiguous because of the inability to provide separate measurements for the H+ and He++ components of the plasma strea

Respiratory failure for as little as 2 min can cause permanent brain damage or death by suffocation. Infants, small children or comatose adults who have had tracheal tubes surgically implanted are vulnerable to this problem, and therefore require con
