The signal coming from the meter's pulse transmitter
is scaled to U.
The External Pulse Transmitter
(EPT), worn outside the body, sends electrical signals through the skin to the implanted lead.
The millimeter-band pulse transmitter
carries energy in a short pulse across an extremely wide band, which must be able to extract only that band needed for transmission.
The key incorporates an electronic pulse transmitter
sending a signal to a proximity sensor in the door, where the signal received is checked and verified.
About 10 pulse transmitters
