Contactless Area Measurement (Contactless Planimeter)

Radioengineering, 2008
The paper describes the designed hardware and software systems (so-called planimeters) for contactless measurement of areas (eventually geometric distances between two selected points) of planar projections of various objects. These systems operate on the principle of processing the video signal scanned by a digital camera (or TV camera).

A Quantitative Printability Framework for Programmable Assembly of Pre‐Vascular Patterns via Laser‐Induced Forward Transfer

Advanced Healthcare Materials, EarlyView.
Laser‐Induced Forward Transfer (LIFT) is presented as a powerful micropatterning tool. An objective printability framework is developed to assess optimal printing parameter combinations. The technology is further explored for its ability to deterministically deposit microdroplets at predefined locations following CAD designs, enabling the patterning of

Design and Experimental Study of Down Hole Contactless Power Transmission Device

Shiyou jixie, 2020
The push-the-bit rotary steerable drilling system needs to transmit the rotating electrical energy to the non-rotating jacket downhole. The traditional contact power transmission form is difficult to adapt to the harsh downhole working environment.
