Antenna pattern recording system has a discretionary signal level monitor which senses a specified minimum level occurring between sampling intervals. This enables RF power and percent coverage to be calculated more accurately.
Digital data acquisition system records steady state and dynamic data of bearing and shaft displacement. Elliptical orbits formed can be reconstructed and the data reduced automatically. System also reads pressures, temperatures, flows, and torque during any one data scan.
Recording head has standard ferrite core directly coated with a thin film of a magnetic alloy composed of aluminum, iron, and silicon. Coated head has a lifespan from five to ten times longer than that of conventional heads and shows superior inductance characteristics and frequency response.
System collects medical data directly from patients and permanently records and displays several parameters - electrocardiograph, electroencephalograph, heart rate, respiration rate, auscultatory blood pressure, leg circumference changes, body temperature, and time. Components and operation of the system are described.
