Claim 8:
9. A system for proximity alert comprising a proximity alert apparatus comprising circuitry supporting at least one radio transceiver and one or more processors, wherein at least one processor stores program instructions to be executed by the processor, the program instructions comprising:
A) loading a configuration value from a non-volatile memory processor and setting a transmission power level for the at least one radio transceiver, based on a loaded first configuration value, to a configuration power level from among a plurality of known power levels;
B) providing a persistent and continuous radio frequency communication relationship utilizing Bluetooth Low Energy (“BLE”) pairing and bonding between the proximity alert apparatus and a protected device comprising a corresponding radio transceiver;
C) providing visual output and auditory output confirmation of successful pairing to a protected device;
D) receiving notice of disconnect of link connectivity between the proximity alert apparatus or system and the protected device from an Open Systems Interconnection (OSI) Bluetooth Low Energy (BLE) link layer;
E) performing a state machine cycle depending upon input and output for at least six proximity alert apparatus operational states comprising:
i) the system for proximity alert is near the protected device,
ii) the system for proximity alert is separated from the protected device,
iii) the system for proximity alert is connected to the protected device,
iv) the system for proximity alert is still,
v) the system for proximity alert is laid down, and
vi) the system for proximity alert is picked up;

F) adjusting the system for proximity alert transmission power level a predetermined increment up or down from the plurality of known standard power levels based upon the system for proximity alert operational state;
G) adjusting the transmission power level of the system for proximity alert at least one radio transceiver up or down by the predetermined increment;
H) saving the system for proximity alert adjusted transmission power level to either a non-volatile memory or a volatile memory dependent on operational state;
I) triggering a selectable auditory system for proximity alert alarm output in response to the protected device being more than a selected distance from the system for proximity alert;
J) triggering an auditory system for proximity alert alarm output in response to the protected device being less than a selected distance from the system for proximity alert;
K) triggering a selectable auditory proximity alert system alarm output in response to a protracted period without link connectivity and historical lack of movement, and then movement; and
L) during runtime execution of the system for proximity alert running an application comprising configuration values during operational states of user inputs in response to one or more system for proximity alert operational states relating to proximity, time, and motion alert inputs and outputs; for individual captured sequences, determining the system for proximity alert integral power savings for each captured sequence regarding one or more operational states; applying an automated response to the captured sequence based on an optimum system for proximity alert integral power savings outcome; storing the captured sequence and the optimum proximity alert integral power savings outcome in a runtime memory within the system alert processor; identifying one or more captured sequences based on the system for proximity alert processor controlled integral power savings real time status associated with the optimum proximity alert integral power savings outcome event confronting the system for proximity alert processor controlled operational state; selecting a captured sequence from the one or more captured sequences, and the control method associated with each individual sequence; and executing the selected captured sequence for the controlled operational state integral power savings method in response to the operational state confronting the proximity alert system.
