November 2007MICS as an Enabling Technology for Wireless Medical Technology
ECN

 

The evolution of wireless healthcare has been significantly influenced by the designation of the 402-405 MHz medical implant communications service (MICS) band. This band is dedicated to radio frequency (RF) communication systems, linking implanted electronic medical devices and control or monitoring equipment.




 
June 2007From Fiction to Fact - Ultra Low-Power Design for Medical Devices
Semiconductor Applications

 

One of the recent announcements from network executives introducing new fall television viewing was the return of The Bionic Woman. When this TV show first aired, a lot of these "bionic" capabilities were for the most part the work of creative, possibly very forward-thinking, television writers. Today, however, with the Bionic Woman set to return to the small screen, many of these once fictional technologies are a reality.




 
June 2007In-Body Communications
RF Design

Targeting implantable applications like pacemakers, nerve stimulators, drug pumps, and other such medical devices, an ultralow-power RF transceiver chip has been developed that delivers high data rates, low power consumption and unique wake-up circuitry. This article discusses the design of an in-body communication system.



 
April 2007Body Implant Communication - Is It a Reality?
IET

 

RF links between implanted medical devices and external monitoring and programming equipment is becoming more common. However, as new RF applications are introduced the battery operating life of the implanted medical device is a concern. This paper describes a technique to prolong battery life.




 
April 2007In-Body Wireless Communication Made Real
IEEE Body Sensor Network 2007

 

This paper take the principle of wireless communication with body implants to the implementation and testing stage. This paper describes a module that can fit into an implant case and results of testing a wireless link with a body model




 
January 2007The Future of Timing: The Transition to Packet Networks
EEPW

 

While the "all-IP" world will eventually be a reality, for an extended period of time synchronization will need to support a hybrid of both the older circuit-switched and the newer packet-based timing interconnections. This article discusses the transition of timing and line card synchronization to support hybrid circuit and packet networks, focusing on the board and chassis level and demonstrating how synchronization may be received from the network and how clocks can be routed internally to the system




 
January 2007Voice Processing for Home Automation Systems
Network systems Design Line

Home networking has evolved from linked personal computers to more complex systems that encompass advanced security and automation applications. Interactive applications operated by voice recognition, for example door security systems and the ability to control home appliances, are key features of home automation networks. This article introduces some of the voice quality performance issues and design challenges unique to home automation systems.
