Claim 17:
18. A non-transitory computer readable memory medium storing program instructions executable by processing circuitry of a proximity alert apparatus or system, the program instructions comprising the steps:
A) loading a configuration value from a non-volatile memory processor and setting a transmission power level for 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 the 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 proximity alert apparatus or system is near the protected device,
ii) the proximity alert apparatus or system is separated from the protected device,
iii) the proximity alert apparatus or system is connected to the protected device,
iv) the proximity alert apparatus or system is still,
v) the proximity alert apparatus or system is laid down, and
vi) the proximity alert apparatus or system is picked up;

F) adjusting the proximity alert apparatus or system transmission power level, a predetermined increment up or down from the plurality of known standard power levels based upon the proximity alert apparatus or system operational state;
G) adjusting the transmission power level of the proximity alert apparatus or system at least one radio transceiver up or down by the predetermined increment;
H) saving the proximity alert apparatus or system adjusted transmission power level to either a non-volatile memory or a volatile memory dependent on operational state;
I) triggering a selectable auditory proximity alert apparatus or system alarm output in response to the protected device being more than a selected distance from the proximity alert apparatus or system;
J) triggering an auditory proximity alert apparatus or system alarm output in response to the protected device being less than a selected distance from the proximity alert apparatus or system;
K) triggering a selectable auditory proximity alert apparatus or 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 proximity alert apparatus or system running an application comprising configuration values during operational states of user inputs in response to one or more proximity alert apparatus or system operational states relating to proximity, time, and motion alert inputs and outputs; for individual captured sequences, determining the proximity alert apparatus or system 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 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 proximity alert apparatus or system processor; identifying one or more captured sequences based on the proximity alert apparatus or system processor controlled integral power savings real time status associated with the optimum proximity alert integral power savings outcome event confronting the proximity alert apparatus or system 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 apparatus or system.
