  • Passive proximity battery control circuit for night vision goggles
    Patent number: 4672194
    Abstract: A circuit for automatically removing battery power from a night vision goggle (10) upon its detachment from a headgear (12). A magnet (34) on the headgear (12) is magnetically coupled to a magnetic reed switch (36) fixed to the goggle (10). On detachment of the goggle (10) from the headgear (12), the reed switch (36) switches battery current to a capacitively coupled coil (52) of a bistable latching relay (K1). Relay (K1) contacts (56, 62) are disconnected thus removing power from the image intensifier tube (40). On reattachment of the goggle (10) to the headgear (12), the On-Off switch (18) is cycled to pulse latching Relay K1 coil (64), thereby establishing a current path to the tube (40).
