Chest Piece Bottom
All electronic stethoscopes manufactured by Rudolf Riester have the same basic
structure.
The stethoscope consists of two elements:
1. Chest piece
2. Cable with plug (USB plug with straight cable or 3.5mm stereo plug with spiral
cable)
3. Operation and Function
3.1 Introduction
The ri-sonic PCP-USB / ri-sonic PCP-1 chestpiece can be used with a general
PC.
The device / PC that supplies power must comply with IEC 60950.
ri-sonic PCP-USB
The ri-sonic PCP-USB stethoscope is intended for use with a standard PC, mobi-
le devices (with USB port) and appropriate app or software, which is not included.
The ri-sonic provides sound data as specified. The user must check whether the
line data of the sensor matches the requirements of the PC, mobile device, app
or software.
The ri-sonic PCP-USB Stethoscope consists of a hardware element, the PCP-
Chest Piece. The PCP-USB Chest Piece contains an embedded piezo sensor,
audio amplifier Analog to Digital Converter (ADC) and Encoder to create a di-
gitized stream, plus a USB interface to send that data to the PC. The ri-sonic
PCP-USB Chest Piece derives its operating voltage from the 5v lead of the USB
interface to the PC.
