In this work, an innovative method for controlling the current distribution of radiating patch by adjusting input phase is investigated to achieve both pattern and polarization reconfigurable characteristics multifunction. A compact low-profile antenna with four fed ports designed implement proposed method, which can operate linear, right-hand circular (RHCP) left-hand (LHCP) different beam dir...

Modular approach and microcontroller technology reduce costs and increase reliability in the Electric aesthetic applications

A complete, working document storage and retrieval system is described. Designed to help users solve the problem of lost documents, this system illustrates the concepts of automatic document capture and easy retrieval. Every document a user copies or prints is automatically indexed and saved for later retrieval. A prototype implementation of such a system was constructed and used daily by appro...

Intuitive myoelectric prosthesis control is difficult to achieve due to the absence of proprioceptive feedback, which forces the user to monitor grip pressure by visual information. Existing myoelectric hand prostheses form a single degree of freedom pincer motion that inhibits the stable prehension of a range of objects. Multi-axis hands may address this lack of functionality, but as with mult...
