We report a means to detect deeply subwavelength pits in optical data-storage media by employing the recently observed giant backscattering perturbation phenomenon of the photonic jet. We conducted microwave experiments with dimensionally scaled-up pits and lands in a simulated optical data-storage device. These measurements were backed up by three-dimensional finite-difference time-domain comp...

We describe a single microfluidic device and two methods for the passive storage of aqueous drops in a continuous stream of oil without any external control but hydrodynamic flow. Advantages of this device are that it is simple to manufacture, robust under operation, and drops never come into contact with each other, making it unnecessary to stabilize drops against coalescence. In one method th...

An electronic individual descriptive record system for storing the individual's identification and descriptive data on a programmable electronic identification and data storage module carried with the individual so that the individual's identification, the individual's descriptive data and the individual itself become one. The system includes an implantable programmable electronic identificatio...

With the increasing pressure on energy and environment, vehicle brake recovery technology is increasingly focused reducing consumption effectively. Based magnetization effect of permanent magnets, this paper presents a novel type magnetic coupling flywheel storage device by combining with technology. As high-efficiency device, it has advantages low consumption, vibration, noise easy maintenance...
