Abstract
Abstract An automatic switching circuit controls operation of a light. The circuit includes a voice recognizer and a manual switch. The switching circuit turns the illuminator on instantly in response to an "ON" command input via the manual switch or via the voice recognizer. The switching circuit turns the illuminator off a predetermined period of time after detecting an "OFF" command input via said manual switch or via the voice recognizer.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
85 words
An automatic illuminator switching circuit comprising: a voice recognizer for detecting a spoken command to turn the illuminator on and a spoken command to turn the illuminator off; an illuminator switch for turning an illuminator on and off; wherein said voice recognizer is connected to control said illuminator switch to turn the illuminator on instantly in response to the command to turn the illuminator on, and to turn the illuminator off a predetermined period of time after detecting the command to turn the illuminator off.
Claim 2
Dependent Claim
85 words
An automatic illuminator switching circuit comprising: a voice recognizer for detecting a spoken command to turn the illuminator on and a spoken command to turn the illuminator off; an illuminator switch for turning an illuminator on and off; wherein said voice recognizer is connected to control said illuminator switch to turn the illuminator on instantly in response to the command to turn the illuminator on, and to turn the illuminator off a predetermined period of time after detecting the command to turn the illuminator off.
Claim 3
Dependent Claim
24 words
An automatic illuminator switching circuit as in claim 1 further comprising: means to sustain an on state of said illuminator switch despite external noises.
Claim 4
Dependent Claim
77 words
An automatic illuminator switching circuit as in claim 2 wherein said means to sustain an on state of said illuminator switch comprises a flip-flop connected between said voice recognizer and said illuminator switch wherein said flip-flop is set by an output of the voice recognizer indicating detection of a spoken command to turn the illuminator on and is reset only at the predetermined time period after the voice recognizer detects a command to turn the illuminator off.
Claim 5
Dependent Claim
37 words
An automatic illuminator switching circuit as in claim 1 further comprising: a preventing device preventing failure to turn off the illuminator after the predetermined period due to noises detected by the voice recognizer during the predetermined period.
Claim 6
Dependent Claim
47 words
An automatic illuminator switching circuit according to claim 4 wherein said preventing device comprises a flip-flop connected between the voice recognizer and the illuminator switch wherein said flip-flop is set by a signal from said voice recognizer indicating detection of a command to turn said illuminator off.
Claim 7
Dependent Claim
110 words
