Both figures show that the centre of the lenses (devoted to far distance) does not reach the nominal distance power of the lens (−3.0 D), being slightly more positive. A higher nominal power of the lenses implies a higher addition, however, this may impact on distance vision. Therefore, this positive over-correction (around 0.5 D) should be taken into consideration by clinicians at the moment o...

Together with the research and development of belt conveyors, diagnostic methods for their reliable operation have been developed. Our is focused on a system method sensing magnetic markers implemented directly into conveyor belt, as in this way, it possible to determine velocity which can be source information about potential malfunction drive unit, control system, or itself. The also used mar...

Introduction Nowadays, interventional cardiology brought a great success to the treatment of many cardiovascular disorders. Despite these great beneficial effects, it has side effects related to the applied techniques. Among them, inflation pressure and pattern of inflation play fundamental role in this regard. By low and very high inflation pressures, the rate of stent thrombosis and in-stent ...

This paper demonstrates a modular architecture of a non-contact actuation micropump setup. Rapid hot embossing prototyping was employed in micropump fabrication by using printed circuit board (PCB) as a mold material in polymer casting. Actuator-membrane gap separation was studied, with experimental investigation of three separation distances: 2.0 mm, 2.5 mm and 3.5 mm. To enhance the micropump...
