Abstract

A movement detector situated within a portable housing is coupled to an access to an entity. The movement detector generates a movement signal upon the vibration or moving of the movement detector. A transmitter transmits a remote motion detection signal via free space upon the receipt of the movement signal. The movement detector is powered by a battery situated within the portable housing thereof. Controller circuitry having an input terminal is coupled to a movement detector receiver which generates an alarm activation signal at an output thereof upon the receipt via free space of the remote motion detection signal. The controller circuitry further has an output terminal for transmitting an alarm activation signal upon receipt of the alarm activation signal at the input terminal thereof. Also included is a transmitter coupled to the output terminal of the controller circuitry for transmitting an alarm signal to a remote location through space upon receipt of the alarm activation signal. Finally, a portable user component is included comprising a receiver for transmitting an alarm activation signal upon receipt of the alarm signal from the transmitter. Alarm means are coupled to the receiver for transmitting an alarm upon receipt of the alarm activation signal.

Claims

1. An alarm system for preventing unauthorized access to an entity comprising, in combination:

a keypad-controlled security mechanism coupled to a conventional door bell, the keypad-controlled security mechanism having a keypad adapted to emit an alarm disarm signal upon the depression of a predetermined sequenced set of keys and further the subsequent depression of the door bell, wherein the keypad has a matrix of keys with numbers and letters printed thereon out of order;

a movement detector situated within a portable housing having a magnet formed thereon for allowing the coupling thereof to an access to an entity, the movement detector having a movement detection means adapted to generate a movement signal upon the movement of the movement detector and a movement detection transmitter connected to the movement detection means for transmitting a remote motion detection signal via free space upon the receipt of the movement signal, wherein the movement detector is powered by a battery situated within the portable housing thereof;

controller circuitry situated within a housing having a first input terminal coupled to the keypad-controlled security mechanism, a second input terminal coupled to a movement detector receiver also situated within the housing which is adapted to generate a first alarm activation signal at an output thereof upon the receipt via free space of the remote motion detection signal, and an output terminal having one mode for transmitting a second alarm activation signal upon receipt of the first alarm activation signal without the receipt of the alarm disarm signal and another mode for precluding the transmission of the second alarm activation signal upon the receipt of the alarm disarm signal;

an alarm with an associated speaker coupled to the output terminal of the controller circuitry for transmitting an audible high frequency alarm signal upon receipt of the second alarm activation signal;

a user-component transmitter located within the housing and coupled to the output terminal of the controller circuitry for transmitting an alarm signal to a remote location through space upon receipt of the second alarm activation signal;

a power source located within the housing and coupled to the keypad-controlled security mechanism, the controller circuitry, the movement detector receiver, and the user-component transmitter for supplying electrical energy thereto, wherein the power source is formed of a main battery and a back-up battery;

a power cable having an interior terminal end and an exterior terminal end with the exterior terminal end coupleable to an external power source for receiving electrical energy therefrom;

a power switch located within the housing and coupled between the internal power source and interior terminal of the power cable with the power switch having a first orientation for allowing electrical energy to be supplied from the main battery of the power source, a second orientation for allowing electrical energy to be supplied from the back-up battery of the power source, and a third orientation for allowing electrical energy to be supplied through the power cable; and

a user component comprising a flexible strap having securement means on one end and securable means on the other end with the securable means coupleable with the securement means in a closed loop configuration about a wrist of a user;

a rigid box-shaped container having a bottom wall coupled to the strap between the ends thereof, a top wall, and a periphery of four side walls interconnecting the top wall with the bottom wall to define a hollow interior;

a receiver disposed within the container for transmitting a third alarm activation signal upon receipt of the alarm signal from the user-component transmitter;

a speaker disposed within the container, coupled to the receiver, and extended through the top wall of the container for transmitting an audible high-frequency alarm upon receipt of the third alarm activation signal;

a battery disposed within the container for supplying electrical energy; and

a power switch coupled between the battery and receiver and extended through the top wall of the container and with the power switch having one orientation for allowing electrical energy to be delivered to the receiver and another orientation for preventing such delivery.

2. An alarm system for preventing unauthorized access to an entity comprising:

a movement detector situated within a portable housing coupled to an access to an entity, the movement detector having a movement detection means adapted to generate a movement signal upon the movement of the movement detector, a movement detection transmitter connected to the movement detection means for transmitting a remote motion detection signal via free space upon the receipt of the movement signal, wherein the movement detector is powered by a battery situated within the portable housing thereof;

controller circuitry having an input terminal coupled to a movement detector receiver which is adapted to generate a first alarm activation signal at an output thereof upon the receipt via free space of the remote motion detection signal and an output terminal for transmitting a second alarm activation signal upon receipt of the first alarm activation signal at the input terminal thereof;

a user-component transmitter coupled to the output terminal of the controller circuitry for transmitting an alarm signal to a remote location through space upon receipt of the alarm activation signal;

a power source coupled to the controller circuitry, the movement detection receiver, and the user-component transmitter for supplying electrical energy thereto;

a user component comprising a receiver for transmitting a third alarm activation signal upon receipt of the alarm signal from the user-component transmitter;

alarm means coupled to the receiver for transmitting an alarm upon receipt of the third alarm activation signal; and

power source means for energizing the receiver; and

a keypad-controlled security mechanism having a keypad adapted to emit an alarm disarm signal upon the depression of a predetermined sequenced set of keys, wherein the controller circuitry is adapted to transmit the second alarm activation signal at the output terminal thereof only upon receipt of the motion detection signal without the receipt of the alarm disable signal and further precludes the transmission of the second alarm activation signal upon the receipt of the alarm disable signal;

wherein the keypad has a matrix of keys with numbers and letters placed out of order.

3. An alarm system for preventing unauthorized access to an entity comprising:
