发明名称 Device for assisting childbirth
摘要 A mechanical to electrical pulse power generator. Powerful rare-earth magnets (e.g., Neodymium-Iron-Boron, or Samarium-Cobalt) create strong flux fields. These flux fields are used to produce large percent change in flux through a coil of wire upon the triggering of triggering mechanisms which causes a snap action to assure creation of an electrical pulse sufficient to activate an alarm. A mechanical force in a first direction will cause a jerk action which will produce a pulse shape identifiable to the first direction force and a mechanical force in a second direction will produce a different jerk action which will produce a pulse shape identifiable to the second direction force. Low power electronics use the energy in these pulses to activate a radio frequency transmitter to transmit a signal revealing the direction of the mechanical force. A preferred embodiment codes the transmitter signal to indicate the source of the signal.
