A frequency reconfigurable circular patch antenna using PIN-diodes is proposed in this paper. This antenna consists of a circular patch with an arc-shaped slot in the ground layer. Three PIN diodes are mounted on the arc-shaped slot to achieve frequency reconfiguration. Full wave simulation and experimental testing are carried out to characterize the antenna's radiation performance. The investigate...
This paper was mainly exploring the important tool for many people who were exchanging knowledge especially proceeding power-point presentation as one auxiliary tool. The lecturer's most proper position should be between the audience and screen of power-point and this location is far away the mouse or keyboard, so if we have designed one facility with wireless control and could be controlled with...
The central monitoring system is made up of four parts. Those are nerve ache RF (radio frequency) treatment modules, physiological signal detecting modules, a communication server, and a central monitoring computer. It can not only treat nerve ache by using RF pulse, but also monitor the ECG, heart sound, temperature and impedance. Both the design circuits of nerve ache RF treatment module and detecting...
As a new pain treatment method, radio frequency (RF) ablation received rapid application and development in the treatment of pain disease in the medicine field. In this paper, we introduce the structure of hardware components and major program modules of the RF treatment system for nerve ache. In the treatment, since the RF trocar is in the body and the body is a perplexing heat exchange system, we...
A conventional 2-dimensional (2D) systolic processing element (PE) array of a chip used for implementing full aearch block matching algorithm (FSBMA) needs a large number of input pads to read sequence image data from SRAM chips. In our work, we embed SRAMs in the FSBMA chip and the PEs read the sequence image data from the embedded SRAMs quickly and directly. Three embedded SRAM arrays are used to...
