Abstract

Abstract The silent alarm comprises a wrist band housing which can be attached to the wrist of a person. A signal receiving device is mounted in the wrist band housing for receiving a signal from a clock controlled transmitter. Vibratory means are also mounted in the housing and are connected to the signal receiving device. A battery is mounted in the wrist band to energize the vibratory means when the signal receiving device receives a signal in order to quietly awaken a sleeping person wearing the wrist band.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 265 words
An electrical alarm clock in combination with a wrist band housing containing a silent waking, device, said alarm clock comprising an alarm clock housing with an electrical alarm clock circuit mounted therein, said housing having a top surface, adapted to support said wrist band, the electrical alarm cluck circuit mounted inside said alarm clock housing and including an ac charging coil mounted in said alarm clock housing close enough to said top surface of the alarm clock housing to influence electrical components on said top surface, said wrist band housing having a wrist band electric circuit mounted therein, said wrist band circuit including an induction coil, said wrist band containing a receiving circuit, a battery, rectifying means connected together along with a charging circuit for charging said battery, and a silent signaling device, said induction coil positioned so the ac voltage and current induced in it from said charging coil when said wrist band is resting on said top surface, generates an ac voltage and current in said induction coil for charging said battery, a silent signaling device in said wrist band housing connected to said battery and said wrist band circuit, a transmitting antenna mounted on said alarm clock housing and connected to said alarm clock circuit in such a way that when the alarm in the alarm clock is triggered, said transmitting antenna transmits a radio wave, said wrist band having a receiver mounted therein and connected to said silent signaling device in such a way that when said receiver receives a signal from said transmitting antenna, it actuates said silent signaling device.
Claim 2
Dependent Claim 265 words
An electrical alarm clock in combination with a wrist band housing containing a silent waking, device, said alarm clock comprising an alarm clock housing with an electrical alarm clock circuit mounted therein, said housing having a top surface, adapted to support said wrist band, the electrical alarm cluck circuit mounted inside said alarm clock housing and including an ac charging coil mounted in said alarm clock housing close enough to said top surface of the alarm clock housing to influence electrical components on said top surface, said wrist band housing having a wrist band electric circuit mounted therein, said wrist band circuit including an induction coil, said wrist band containing a receiving circuit, a battery, rectifying means connected together along with a charging circuit for charging said battery, and a silent signaling device, said induction coil positioned so the ac voltage and current induced in it from said charging coil when said wrist band is resting on said top surface, generates an ac voltage and current in said induction coil for charging said battery, a silent signaling device in said wrist band housing connected to said battery and said wrist band circuit, a transmitting antenna mounted on said alarm clock housing and connected to said alarm clock circuit in such a way that when the alarm in the alarm clock is triggered, said transmitting antenna transmits a radio wave, said wrist band having a receiver mounted therein and connected to said silent signaling device in such a way that when said receiver receives a signal from said transmitting antenna, it actuates said silent signaling device.
Claim 3
Dependent Claim 53 words
The electrical alarm clock and body embracing band housing described in claim 1 wherein said silent signaling device is a vibrator positioned close enough to the skin of the person wearing the said band housing so that the person wearing the said band housing is awakened by the vibration of the band housing.
Claim 4
Dependent Claim 48 words
The electrical alarm clock described in claim 2 wherein a band receiving groove is formed in said top surface of said alarm clock housing so that the battery in the body embracing band housing can be charged when the band housing is laid in said band receiving groove.
