1. A proximity detection alarm device, comprising:

  • a first unit, said first unit comprising a first Bluetooth system comprising one transceiver;

    at least one alarm;

    at least one control;

    a power input;

    an attachment mechanism,an ear piece;

    said ear piece operatively connected to the main body of said first unit so that said ear piece can fold against and unfold away from said main body of said first unit;

    wherein said device will fit into a space having a volume less than 18 cubic centimeters, wherein said device has a weight less than about 50 grams, and wherein said device consumes less than 50 mAh,wherein said first Bluetooth system can pair with a second Bluetooth system in a first range,wherein said attachment mechanism is selected from the group consisting of a key chain, a ring, a hook, a notebook security lock, an insert, a pin, a clip, a tee, a collar, Velcro fastener, a ring, a wire, a case, a badge and a sticky surface,wherein said transceiver of said first Bluetooth system is selected from the group consisting of class 1, class 2, class 3, and Wibree,wherein said first Bluetooth system is set to use a profile selected from the group consisting of HFP profile, HSP profile, HID profile, AGHFP profile, A2DP profile, and SPP profile,wherein following connection with a second Bluetooth system, said first Bluetooth system will utilize a power saving mode,wherein said at least one control comprises at least one of the group consisting of a button, a switch, and a sensor,wherein said at least one alarm is audible and when activated produces an alarm signal of at least 60 decibels,wherein upon said first Bluetooth system detecting a connection drop from a second Bluetooth system to which said first Bluetooth system has formed a pair, said first Bluetooth system will periodically attempt to reconnect to the second Bluetooth system,wherein said alarm will be activated within a predetermined time after a connection drop between said first Bluetooth system and a second Bluetooth system to which said first Bluetooth system has formed a pair,wherein when folded said proximity detection alarm device functions as a Bluetooth headset, andwhen unfolded said proximity detection alarm device activates said alarm upon a disconnection for the predetermined time.
