Electronic Stethoscope Reference Design Leverages Wireless Sensor Platform

Posted by Tim Gee on Oct 3, 2005 in Company Profiles, Standards & Regulatory | 0 comments

AMI Semiconductor released
a reference design
for a DSP-based electronic stethoscope today. The advantages offered
by this technology includes improved clarity, amplification, and the
ability to store and play back multiple samples. Vendors like
3M/Littmann, Welch Allyn and others may find this reference design of
interest.

After a quick scan of the
technical info
behind the reference design, we find the following features:

• DSP that supports user interface, local data
  storage/retrieval and software-based signal processing and
  analysis
• Very low power consumption with “smart”
  power management
• Platform
  connectivity for LCD and wireless (Bluetooth)
• Extended product life cycles suitable for embedded medical
  devices

Sounds like the makings of a nice wireless sensor
platform, doesn't it?
