Under increasing time-to-market pressures in the electric drives industries, the development time of new algorithms and new control systems including their debugging time must be minimized. This requirement can be satisfied only by using a well-defined system-level design methodology and by reducing the migration time between the algorithm development language and the hardware specification lan...

This TechNote introduces a novel interaction technique for small screen devices such as palmtop computers or hand-held electric devices, including pagers and cellular phones. Our proposed method uses the tilt of the device itself as input. Using both tilt and buttons, it is possible to build several interaction techniques ranging from menus and scroll bars, to more complicated examples such as ...

It is well known that electro-hydrodynamical effects in freely suspended liquid films can flow the liquid. Here we report a purely electrically driven rotation in water and some other liquid suspended films with full control on the velocity and the chirality of the rotating vortices. The device, which is called “film motor”, consists of a quasi two-dimensional electrolysis cell in an external i...

A nonlinear microwave phase shifter based on ferrite-ferroelectric composite material has been studied for the first time. The ferrite-ferroelectric composite is fabricated in the form of bilayer consisted of yttrium iron garnet and barium strontium titanate. A principle of operation of the device is based on the linear and nonlinear control of the phase shift of the hybrid spinelectromagnetic ...

The control for the processing of precursor liquids determines whether the properties and functions of the final material product can be engineered. An inherent challenge of processing viscous liquids arises from their large resistance to deform. Here, we report on the discovery of an electric approach that can significantly contribute to address this challenge. The applied electric force can i...

This paper discusses the Dynamic voltage restorer (DVR) operation and control for Voltage sags compensation. DVR is a series connected power electronic based device that can quickly mitigate the voltage sags in the system and restore the load voltage to the pre-fault value. Voltage sag associated with faults in transmission and distribution systems, energizing of transformers, and starting of l...

The programmable logic controller (PLC) is an industrial control computer; it is the new automatic device inherited computer, automatic control technology and communication technology. System temperature signal detected by the temperature sensor. The temperature transmitter will be the temperature value converted into a voltage signal of 0-10V into PLC. PLC voltage signal setting compared to th...

In previous research, we used the corresponding theory of micro-chip as the base to develop an Electric-type Keyboard, Mouse and Monitor Switcher (EtKMMS). The proposed EtKMMS device has circumvented the problem of the traditional mechanic switcher and we have obtained some successful results in the simulation tests. In this paper, we implement the proposed EtKMMS in the industrial proceeding c...

Legacy transformers are passive, bulky, becoming expensive, and take longer time to deliver. They cannot provide the power quality or control which today’s loads demand for proper functioning and the electric system needs for its survivability. Solid-state transformers have been promising technologies in recent years. EPRI is pursuing development of an innovative solution – the IUTTM (Intellige...

Ionic crystals play a crucial role in many well‐established technologies as well as highly exotic, cutting‐edge research materials. In ionic crystals, bonding between the (inter)metallic atoms and ions, such as oxygen or nitrogen, gives rise to interactions which then manifest new and interesting behaviours and control the fundamental properties of materials. Control over the ion distribution t...
