Firearms protected from unauthorized use are disclosed. A disclosed firearm comprises a housing having a handle; a safety located in the housing to selectively prevent firing; and a module removably attachable to the handle and containing an electronic identification device to identify an authorized user. The electronic identification device controls the safety to prevent firing by unauthorized persons and to permit firing by the authorized user.

What is claimed is: 1. A firearm comprising: a housing defining a shaft to releasably receive a magazine; an electronic component located in the housing; an accumulator to temporarily store energy; and a generator at least partially contained within the housing to supply current to the accumulator

What is claimed is: 1. A firearm comprising: a housing defining a shaft to releasably receive a magazine; an electronic component located in the housing; an accumulator to temporarily store energy; and a generator at least partially contained within the housing to supply current to the accumulator in response to movement of a magnet mounted to the magazine, wherein the generator comprises a coil positioned along a periphery of the shaft to generate current in response to insertion or removal of the magnet carried by the magazine into or out of the shaft. 2. A firearm as defined in claim 1, wherein the housing includes a handle, and wherein the magazine is stored in the handle. 3. A firearm as defined in claim 1, wherein the generator further comprises a piezoelectric element positioned such that recoil stress caused by firing of a shot causes the piezoelectric element to generate current. 4. A firearm as defined in claim 1, further comprising: a safety located in the housing to selectively prevent firing; and a module attachable to the housing and containing an electronic identification device to identify an authorized user, the electronic identification device controlling the safety to prevent firing by unauthorized persons and to permit firing by the authorized user. 5. A firearm as defined in claim 4, further comprising a memory associated with the electronic identification device. 6. A firearm as defined in claim 4, wherein the electronic identification device is powered by the current generated by movement of the magnet of the magazine. 7. A firearm as defined in claim 1, wherein the housing includes a handle, and the magazine is stored in the handle. 8. A firearm as defined in claim 4, further comprising a piezoelectric element positioned in at least one of the housing and the module such that recoil stress caused by firing of a shot causes the piezoelectric element to generate current to at least partially power the electronic identification device. 9. A firearm as defined in claim 8 wherein the recoil stress is a result of movement of a recoil spring, a breech, or a powder-gas driven device. 10. A firearm as defined in claim 4, wherein the magazine further comprises an identification code which is read and recorded by the electronic identification device. 11. A firearm as defined in claim 10 wherein the electronic identification device evaluates the identification code associated with the magazine to identify the authorized user. 12. A firearm as defined in claim 4, further comprising a microphone coupled to the electronic identification device. 13. A firearm as defined in claim 12, wherein the electronic identification device comprises a voice recognition device or a word recognition device. 14. A firearm as defined in claim 13, wherein the voice recognition device is structured to recognize a normal voice, a whisper and a hoarse voice of the authorized user. 15. A firearm as defined in claim 13, wherein the word recognition device is structured to recognize a word spoken in a normal voice, a whisper and a hoarse voice of the authorized user. 16. A firearm as defined in claim 13, wherein the microphone is connected with a memory which records data indicative of spoken commands from the authorized user. 17. A firearm as defined in claim 16, further comprising a timer or time signal receiver, and wherein the data indicative of the spoken commands comprises a firing time. 18. A firearm as defined in claim 12, wherein the microphone is connected with a memory which records data reflecting firing of shots. 19. A firearm as defined in claim 18, further comprising a timer or time signal receiver, and wherein the data reflecting firing of shots comprises a firing time. 20. A firearm as defined in claim 18, wherein more than one user is the authorized user, and the data reflecting firing of shots comprises an identification of the user responsible for the shots. 21. A firearm as defined in claim 5, wherein the memory stores an event indicative of a maintenance requirement of the firearm. 22. A firearm as defined in claim 4, wherein the electronic identification device comprises a sensor for iris recognition, the sensor being directed toward an expected location of an aiming eye of a user attempting to fire the firearm. 23. A firearm as defined in claim 4, wherein the safety prevents firing when the module is removed from the housing. 24. A firearm as defined in claim 4, further comprising a blank module for installation in place of the module. 25. A firearm as defined in claim 24, wherein the blank module is incapable of releasing the safety. 26. A firearm as defined in claim 24, wherein the blank module releases the safety. 27. A firearm as defined in claim 4, further comprising a contact sensor to activate the safety. 28. A firearm as defined in claim 5, wherein the firearm has a firearm identification number and the firearm identification number is written to the memory to record an attachment of the module to the firearm.
