Mr. Zaidi will be talking about the basics of System On Chip(SOC), Embedded Systems Technology and its Applications. Later he would talk about his company namely PalmChip, USA and finally the prospects of Pakistani youth in this emerging field.
MRI (Magnetic Resonance Imaging) is a very useful medical procedure to get high quality images inside the body. Felix Bloch and Edward Purcell discovered the magnetic resonance phenomenon independently in 1946. They were awarded the Nobel Prize in 1952. The use of MRI is increasing every day and has become a very useful tool for diagnosis. However, patients with artificial implants, e.g. heart pace makers, DBS (Deep Brain Stimulation) systems, which are used for Parkinson’s disease, IPG (Implantable Pulse Generator), used for generating pulses for DBS, are in severe danger for MRI testing.
Wireless communications for mobile telephone and data transmission is currently undergoing very rapid development. The emerging wireless systems will incorporate considerable signal processing intelligence in order to provide advanced services such as multimedia transmission. In order to make optimum use of available bandwidth, many wireless systems operate as multiple access systems, e.g. Direct Sequence Code Division Multiple Access (DS-CDMA), in which the users are multiplexed by distinct code waveforms. Two major factors that limit the performance of DS-CDMA systems are multiple access interference and multipath channel distortion. Many advanced signal processing techniques have been proposed to combat these factors. Among these techniques, one of the more promising is the use of Smart or Adaptive antennas.
Electronic devices have seen tremendous improvement since the discovery of electron. A brief history of the progress in microelectronics industry will be presented with emphasis on memory devices and information technology (IT). The limiting factors in the future progress will be discussed, and need for new concepts and devices will be established. Results of memories and logic circuits based on silicon nano-wires as single electron tunneling transistors (SETTs) will also be presented. Microelectronics research at Cavendish laboratory has resulted in a new device named PLEDM.
