Voice Lock Promises Keyless Home Entry by Speech
Dr Irving H Sher of Philadelphia has invented a voice operated door lock that unlocks only to a specific spoken command by designated persons. A Sceptron sensor analyzes speech through a light system to confirm the correct voice, and the device can be set for multiple authorized users. Patent 3,184,937 is assigned to the Institute for Scientific Information.
