Abstract: Effectiveness and safety of external cardiac resuscitation is increased by the use of a small inflatable "pillow" which has a pressure gauge calibrated to read out the downward force or pressure applied to the victim's chest. The device is placed on the victim's chest and force is applied onto the device allowing the user to observe and control the force or pressure being applied to the victim.

Abstract: An ingestible drug delivery device is designed so that direct contact by undissolved drug with the stomach lining is avoided.

Abstract: A method and apparatus for testing the condition of an antenna monitoring system are provided whereby a sampling loop and coaxial cable assembly may be provided for each antenna element and wherein each such assembly is normally terminated with a first impedance. The magnitude of current flowing through the normally terminated assembly or monitoring system is measured at a time when the antenna system and the monitoring system are known to be operating in a desired condition. An additional impedance is then placed in circuit with the first impedance and the new magnitude or offset value of current flowing through the assembly is measured. If the ratio or the difference between the normally terminated value of current and the offset value of current changes from the originally established base value, there is a strong liklihood that there is an abnormality in the sampling loop and cable assembly and probably not in the antenna system itself.
