V38-1   Boulitte Electrocardiograph [Boulitte]

The Boulitte Electrocardiograph is an instrument to observe the electrical activity of the human heart. The instrument consists of a projector on the right side, a film camera on the left and a telescopic projection tunnel in between. In the tunnel an electrically conductive string is mounted vertically, between two magnetic coils placed around the tunnel. The projector lamp sends a light beam through the tunnel. This beam will pass the vertical string fed by electrical signals from the human heart. The string will fibrate due to a varying heart signal in the magnetic field. This construction – developed by fysiologist Willem Einthoven in 1901 in Leiden - is called a string galvanometer as it measures electrical currents. While the string moves it will draw a shadow within the beam. The light beam is projected through a small horizontal slit of the camera. The shadow region in the light projection is captured on a running film. As a result just an ECG on film is delivered.

Data Aquisitiion/Control Unit [3421A] [Hewlett Packard]

The 3421A was an HP-IL interfaced data acquisition/control unit. It was developed for connection to HP-41 handheld calculator (and later to the HP-71B). The 3421A also offered an optional HP-IB interface for connection to HP computers, usually the HP-85. The 3421A also offered an optional battery for remote operation. The 3421A scanned up to 30 channels measuring DC and AC voltage. Three options were available including: 10-channel multiplexer ($290), breadboard assembly and 8-bit digital I/O assembly. bron https://hpmuseum.net/display_item.php?hw=1109
