Electronic_Stethoscope

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?
