Energy Generator / Energy Bow
Converts the motion of the energy bow into electrical energy. This is the main energy
source for the PTM Modules.
Energy Converter
Converts the energy of the power generator into a stable DC supply voltage for the device
electronics.
Energy Managemetn
Secures energy supply of the module for the required period. The generator provides an
burst of energy which needs to be conserved for the much longer period than the burst
lasts.
Microcontroller
Determines the status of the contact nipples and the energy bow, encodes this status into a
EnOcean Data telegram, if required it encrypts this data and computes the CMAC,
generates the proper radio telegram structure and sends it to the radio transmitter.
RF transmitter
Transmits the data in the form of a series of short EnOcean radio telegrams.
Contact Nipples
Via the 4 nibbles rockers or other custom plastics can code specific information into the ra-
dio telegram triggering different functions at the receiver.
NFC Interface
