A prototype of a one-time-implantable spinal cord stimulation (SCS) system using wireless power and data-transmission techniques is presented in this paper. The power of the implant is induced by wireless coil coupling, and duplex amplitude-shift keying-load-shift keying wireless communication is used so that digital packets can be transmitted by the same inductive link. The proposed novel ASK demodulator...
This study presents a prototype of a one-time implantable spinal cord stimulation system (SCS) using wireless power and bidirectional data transmission by an inductive link. The data can be transmitted by an inductive link, which is based on a duplex ASK-LSK technique. A fabrication chip is integrated in the bio-implant to generate stimulation waveform control signals. The chip area is 1800 × 1250...
This paper presents a bus guardian design used in an in-car network compliant with FlexRay standards. FlexRay is a new standard for data/signal communication among electronic devices installed in a vehicle. An 8051-compatible microcontroller was used to implement the system controller. Most important of all is that the bus guardian (BG) in charge of security and safty is proposed and implemented....
