Portable reverse alarm system

摘要

A portable alarm system for notifying a user of theft or movement of an object when the user is at a distance from the object. The portable alarm system may generally comprise a sensor unit and a remote unit. The sensor unit may be placed on or embedded within an object to be protected and have one or more sensors for detecting vibration and/or motion of the sensor unit and thereby the object. The sensor unit is activated when vibration or movement input exceeds a predetermined trigger level value. When the trigger level value is exceeded, an alarm signal is transmitted to the remote unit. The remote unit receives the alarm signal and may generate one or more alarms to indicate object vibration or movement. The one or more alarms may include but are not limited to an audible buzzer, light indicators, and remote unit vibration.

1. An alarm system comprising:
a portable sensor unit comprising at least one sensor in electrical communication with at least one sensor unit transceiver, said at least one sensor having a sensor trigger level and wherein said at least one sensor unit transceiver is adapted to transmit an alarm signal when said sensor trigger level is exceeded; a portable remote unit comprising at least one remote unit transceiver and at least one alarm in electrical communication with said remote unit transceiver; wherein said remote unit transceiver is adapted to receive said alarm signal from said at least one sensor unit transceiver, and wherein said at least one remote alarm is adapted to produce an alarm indication when said at least one remote unit transceiver receives said alarm signal; wherein said at least one sensor is further comprised of a plurality of sensors selected from the group consisting of vibration sensors, noise sensors, and motion sensors; wherein said at least one sensor unit transceiver and said at least one remote unit transceiver are further defined as radio frequency transceivers; wherein said at least one sensor unit is further comprised of a sensor unit microcontroller in electrical communication with said at plurality of sensors; and
said sensor unit microcontroller is in electrical communication with said at least one transceiver; andsaid at least one sensor unit is further comprised of a sensor unit microcontroller readable memory containing instructions for determining that a predefined sensor trigger level has been exceeded and causing said sensor unit transceiver to transmit said alarm signal to said remote unit; and wherein said sensor unit is further comprised of a switch in electrical communication with said sensor unit microcontroller wherein said switch is adapted to turn said sensor unit off, and wherein said sensor unit microcontroller readable memory is further comprised of instructions to cause said sensor unit transceiver to transmit a signal to said remote unit transceiver indicating that said sensor unit is off.
