Low pressure warning system with automatic transfer

Low pressure warning system with automatic transfer.

C. S. WARD 1 has described previous devices used to indicate failure of oxygen supply. These include the '%osun" warning device, the Wantage oxygen failure alarm, 2 the Coote warning device, a the Adler and Burn device, 4 the "fail safe" oxygen device, 5 and the ECC gas failure alarm. 6 The reader is referred to Ward's paper for descriptions. It is evident from the above list that a warning sys...

Automatic earthquake confirmation for early warning system

Earthquake early warning studies are shifting real-time seismology in earthquake science. They provide methods to rapidly assess earthquakes to predict damaging ground shaking. Preventing false alarms from these systems is key. Here we developed a simple, robust algorithm, Authorizing GRound shaking for Earthquake Early warning Systems (AGREEs), to reduce falsely issued alarms. This is a networ...

Collision Warning System using Ultrasonic Sensors and Automatic Brake System

Vehicle technology has increased rapidly in recent years, particularly in relation to braking system and sensing system. In parallel to the development of braking technologies, sensors have been developed that are capable of detecting physical obstacles, other vehicles or pedestrians around the vehicle. This development prevents accidents of vehicles using Stereo Multi-Purpose cameras, Automate...

A New System of Contactless Power Transfer with Low Voltage Stress and Parasitic Capacitors Effect

In this paper, a high frequency contactless power transfer (CPT) system is designed with ∅2 inverter drive. This system works in 30MHz frequency and 380W power with low voltage stress and considers the inductive link parasitic capacitor effect. In the design, we formulated the inverter equations first and then suggested another design for the transmitter and the receiver coils as the energy tra...
