Abstract

The mechanical and electrical design of the connec- tion of the battery to the radio could be altered so that the radio battery can be changed without loss of power to the radio. This will prevent volatile data in the radio from being lost and having to be reentered by the radio operator or m-acquired from information transmitted to the radio after battery change.

RADIO BATTERY CHANGE WITHOUT POWER LOSS

by Patrick Conduit

  The mechanical and electrical design of the connec- tion of the battery to the radio could be altered so that the radio battery can be changed without loss of power to the radio. This will prevent volatile data in the radio from being lost and having to be reentered by the radio operator or m-acquired from information transmitted to the radio after battery change.

  In addition, the connection of the battery to the radio could be made so that it is very diicult/impossible to remove the battery which is currently powering the radio without inserting a new battery in its place. Combined with a disabled power On/Off switch this design would make it very difficult to stop radio emergency type operation.

  Electronic circuitry will be required in the radio to prevent current flow between the two batteries whilst they arc both connected to the radio.

  Drawings describe design for portable radio which has battery mounted on back of radio. Ideas could also be applied to radios which have battery mounted on bottom of radio.

  An alternative to prevent loss of power to radio is to have a large back up capacitor in radio which can power radio for a short time whilst battery is changed. Disad- vantages ofthis are:

* Capacitor takes up space. * Does not prevent the battery being removed with- out another being replaced leading to eventual loss of power.
