A starting device for a metal plasma source

Instruments and Experimental Techniques, 2008
An explosion of a thin self-renewable carbon film is used for initiating an arc in a vacuum-arc metal plasma source, which makes operation of the device independent of the operating mode of the plasma source and allows the circuit of the setup to be simplified, since there is no need for generating high-voltage triggering pulses.

Sailing/Coasting Enabled by Mechatronic Starting Devices

2020
Engine start quality and seamless engine start/stop are key elements of drive quality and customer acceptance in today’s electrified propulsion architectures. Two novel mechatronic devices have been created for premium engine start/stop. One concept uses a motor/generator in place of the traditional alternator, coupled to a mechatronic switching device

Device‐Associated Infections: A Macroproblem that Starts with Microadherence

Clinical Infectious Diseases, 2001
Medical devices are responsible for a large portion of nosocomial infections, particularly in critically ill patients. Device-associated infections can cause major medical and economic sequelae. Bacterial colonization of the indwelling device can be a prelude to both infection and malfunction of the device.

THE WIND RECEIVING DEVICE WITH A STARTING MODULE

Elektrotekhnologii i elektrooborudovanie v APK
Most of the territory of Russia is located in places with average periodic wind speeds of 2-5 meters per second and in such conditions high-speed wind power plants operate no more than 20 percent of the time a year, which leads to low annual production.
