Abstract
Abstract An alarm clock comprising a housing, electronic clock means including time and alarm setting means, tine indicator signal means, alarm signal generating means, and alarm off signal input means, wherein the reception of an alarm of signal disables the generation of the alarm signal, battery means connected to said electronic clock means for supplying power to said electronic clock means, a time display mounted in the face of said housing and connected to said time indicator signal means, first solid state switch means connected and responsive to said alarm signal generating means, sound generating means disposed in said housing, vibration generating means mounted to the interior of said housing, alarm mode switch means for selectively switching between alarm off and audible and vibratory alarm modes.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
331 words
An alarm clock comprising: a substantially flat, rectangular housing; electronic clock means disposed in said housing, said electronic clock means including time and alarm setting means, time indicator signal means, alarm signal generating means, and alarm off signal input means, wherein the reception of an alarm off signal disables the generation of the alarm signal; first battery means disposed in said housing and connected to said electronic clock means for supplying power to said electronic clock means; a time display mounted in the face of said housing and connected to said time indicator signal means of said electronic clock means; first solid state switch means disposed in said housing, said first solid state means being connected and responsive to said alarm signal generating means; sound generating means disposed in said housing; vibration generating means mounted to the interior of said housing; alarm mode switch means for selectively switching between alarm off and audible and vibratory alarm modes, said alarm mode switch means mounted in said housing and having user accessible means, said alarm mode switch means being connected to said first solid state switch means, said sound generating means, said vibration generating means and said alarm off signal input means, whereby when said alarm mode switch means is set to the alarm off mode, said alarm off signal is applied to said alarm off signal input means; said sound generating means being selectably connected to said first solid state switch means through said alarm mode switch means, said sound generating means generating an audible alarm when said sound generating means is connected to said first solid state switch means and said alarm signal generating means generates an alarm signal; and said vibration generating means being selectably connected to said first solid state switch means through said alarm mode switch means, said vibration generating means generating perceptible vibrations when said vibration generating means is connected to said first solid state switch means and said alarm signal generating means generates an alarm signal.
Claim 2
Dependent Claim
331 words
An alarm clock comprising: a substantially flat, rectangular housing; electronic clock means disposed in said housing, said electronic clock means including time and alarm setting means, time indicator signal means, alarm signal generating means, and alarm off signal input means, wherein the reception of an alarm off signal disables the generation of the alarm signal; first battery means disposed in said housing and connected to said electronic clock means for supplying power to said electronic clock means; a time display mounted in the face of said housing and connected to said time indicator signal means of said electronic clock means; first solid state switch means disposed in said housing, said first solid state means being connected and responsive to said alarm signal generating means; sound generating means disposed in said housing; vibration generating means mounted to the interior of said housing; alarm mode switch means for selectively switching between alarm off and audible and vibratory alarm modes, said alarm mode switch means mounted in said housing and having user accessible means, said alarm mode switch means being connected to said first solid state switch means, said sound generating means, said vibration generating means and said alarm off signal input means, whereby when said alarm mode switch means is set to the alarm off mode, said alarm off signal is applied to said alarm off signal input means; said sound generating means being selectably connected to said first solid state switch means through said alarm mode switch means, said sound generating means generating an audible alarm when said sound generating means is connected to said first solid state switch means and said alarm signal generating means generates an alarm signal; and said vibration generating means being selectably connected to said first solid state switch means through said alarm mode switch means, said vibration generating means generating perceptible vibrations when said vibration generating means is connected to said first solid state switch means and said alarm signal generating means generates an alarm signal.
Claim 3
Dependent Claim
59 words
The alarm clock of claim 1 further comprising second battery means disposed in said housing and connected to said sound generating means and said vibration generating means for supplying power to said sound generating means and said vibration generating means, wherein said first battery means does not provide power for said sound generating means and said vibration generating means.
Claim 4
Dependent Claim
24 words
The alarm clock of claim 2 wherein said vibration generating means comprises a dc motor with a weight eccentrically disposed on its drive shaft.
Claim 5
Dependent Claim
21 words
The alarm clock of claim 3 wherein said vibration generating means further comprises capacitive means disposed across said dc motor's terminals.
Claim 6
Dependent Claim
77 words
The alarm clock of claim 4 further comprising second solid state switch means disposed in said housing, said second solid state switch means being connected between said vibration generating means and said first solid state switch means through alarm mode switch means, whereby said vibration generating means is responsive to said alarm signal when said alarm mode switch means is set to selectively connect said second solid state switch means to said first solid state switch means.
Claim 7
Dependent Claim
42 words
The alarm clock of claim 5 wherein said first solid state switch means is a npn transistor with its base connected to said alarm signal generating means, its collector connected to said alarm mode switch means, and its emitter connected to ground.
Claim 8
Dependent Claim
71 words
The alarm clock of claim 6 wherein said second solid state switch means is a pnp transistor with its base connected to said alarm mode switch means, its emitter connected to the positive side of said second battery means and its collector connected to one terminal of said dc motor, with the negative side of said second battery means and the other terminal of said dc motor being connected to ground.
