Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
162 words
An electronic reminder for a usable personal article having a fixed general orientation during use thereof, said electronic reminder comprising a gravity activated position sensing switch, a battery, an electrically activated audio generator, and a compartment within said article for containing said position sensing switch, battery, and generator; which position sensing switch is for triggering the audio generator by a specified deviation of said article from said fixed general orientation; which usable personal article is a lighter; and said electronic reminder includes a switch attached to the lighter flintlock switch is triggered synchronously with the flintlock as the flintlock is cocked to light said lighter, and a shutting button; which flintlock switch is for switching the electronic reminder from an off-condition in which said position sensing switch cannot trigger said audio generator, to an on-condition in which said position sensing switch can trigger said audio generator, and which shutting button is for returning said electronic reminder from said on-condition to said off-condition.
Claim 2
Dependent Claim
162 words
An electronic reminder for a usable personal article having a fixed general orientation during use thereof, said electronic reminder comprising a gravity activated position sensing switch, a battery, an electrically activated audio generator, and a compartment within said article for containing said position sensing switch, battery, and generator; which position sensing switch is for triggering the audio generator by a specified deviation of said article from said fixed general orientation; which usable personal article is a lighter; and said electronic reminder includes a switch attached to the lighter flintlock switch is triggered synchronously with the flintlock as the flintlock is cocked to light said lighter, and a shutting button; which flintlock switch is for switching the electronic reminder from an off-condition in which said position sensing switch cannot trigger said audio generator, to an on-condition in which said position sensing switch can trigger said audio generator, and which shutting button is for returning said electronic reminder from said on-condition to said off-condition.
Claim 3
Dependent Claim
118 words
An electronic reminder for a usable personal article having a fixed general orientation during use thereof, said electronic reminder comprising a gravity activated position sensing switch, a battery, an electrically activated audio generator, and a compartment within said article for containing said position sensing switch, battery, and generator; which position sensing switch is for triggering the audio generator by a specified deviation of said article from said fixed general orientation; which usable personal article is a pen; and said electronic reminder includes a shutting button for switching said electronic reminder from an on-condition in which said position sensing switch can trigger said audio generator to an off-condition in which said position sensing switch cannot trigger said audio generator.
Claim 4
Dependent Claim
118 words
An electronic reminder for a usable personal article having a fixed general orientation during use thereof, said electronic reminder comprising a gravity activated position sensing switch, a battery, an electrically activated audio generator, and a compartment within said article for containing said position sensing switch, battery, and generator; which position sensing switch is for triggering the audio generator by a specified deviation of said article from said fixed general orientation; which usable personal article is a pen; and said electronic reminder includes a shutting button for switching said electronic reminder from an on-condition in which said position sensing switch can trigger said audio generator to an off-condition in which said position sensing switch cannot trigger said audio generator.
Claim 5
Dependent Claim
20 words
An electronic reminder in accordance with claims 1 or 2 in which said specified deviation is a substantially horizontal orientation.
Claim 6
Dependent Claim
34 words
An electronic reminder in accordance with claims 1 or 2 in which said gravity activated position sensing switch is a mercury switch, and said audio generator includes an IC oscillator and a miniature loudspeaker.
