ANALYSIS OF STIMULUS BY RFID
The present invention is directed to a stimulus monitoring process. The process includes exposing an RFID device to an environment. The RFID has characteristics that alter based on exposure to the environment, which in turn alter a response signal emanating from the RFID device in response to an interrogation signal.
1 . A stimulus monitoring process comprising:
exposing an RFID device to an environment, wherein said RFID device comprises:
an inductor with a voltage potential;
a conductive trace having a substantially elastic connection with said inductor;
a deformable brace, positioned proximate to said inductor, constructed from a material structurally, selectively deformable in response to a predetermined external stimulus characteristically found in said environment such that upon exposure to said stimulus said inductor flexes in concert with said brace to substantially alter said voltage potential; and
an antennae complex, in electrical communication with said inductor, initially adapted to accept a predetermined, base frequency and transmit a response signal, measurably distinct from said base frequency, based on said voltage potential.
2 . The process of claim 1 further comprising altering said voltage potential by exposure of said RFID device to said environment.
3 . The process of claim 1 further comprising associating an item with said RFID device such that said item and said RFID device receive comparable exposure to said environment.
4 . The process of claim 1 further comprising transmitting an interrogation signal, the characteristics of which are informed by said predetermined base frequency, in the proximity of said item.
5 . The process of claim 4 further comprising receiving said response signal from said RFID device.
6 . The process of claim 5 further comprising comparing said response signal to said predetermined base signal to produce a deviation value.
7 . The process of claim 6 further comprising utilizing said deviation value to calculate a property of said item.
8 . The process of claim 7 further comprising adjusting a use of said item based on said property of said item.
9 . A stimulus monitoring process comprising:
exposing an RFID device to an environment, wherein said RFID device comprises:
a capacitor with a voltage potential;
a conductive trace having a substantially elastic connection with said capacitor;
a deformable brace, positioned proximate to said capacitor, constructed from a material structurally, selectively deformable in response to a predetermined, external stimulus such that upon exposure to said stimulus said capacitor flexes in concert with said brace to substantially alter said voltage potential; and
an antennae complex, in electrical communication with said capacitor, initially adapted to accept a predetermined, base frequency and transmit a response signal, measurably distinct from said base frequency, based on said voltage potential.
10 . The process of claim 9 further comprising altering said voltage potential by exposure of said RFID device to said environment.
11 . The process of claim 9 further comprising associating an item with said RFID device such that said item and said RFID device receive comparable exposure to said environment.
12 . The process of claim 9 further comprising transmitting an interrogation signal, the characteristics of which are informed by said predetermined base frequency, in the proximity of said item.
13 . The process of claim 12 further comprising receiving said response signal from said RFID device.
14 . The process of claim 13 further comprising comparing said response signal to said predetermined base signal to produce a deviation value.
15 . The process of claim 14 further comprising utilizing said deviation value to calculate a property of said item.
16 . The process of claim 15 further comprising adjusting a use of said item based on said property of said item.
17 . A stimulus monitoring process comprising:
exposing an RFID device to an environment, wherein said RFID device comprises:
a circuit comprising a series of RFID subcomponents interconnected via a conductive trace;
a deformable brace, positioned proximate to said circuit, constructed from a material structurally, selectively deformable in response to a predetermined external stimulus such that upon exposure to said stimulus said brace flexes to contort said circuit to substantially alter a voltage potential across said circuit; and
an antennae complex, in electrical communication with said circuit, initially adapted to accept a predetermined, base frequency and transmit a response signal, measurably distinct from said base frequency, based on said altered voltage potential.
18 . The process of claim 17 further comprising altering said voltage potential by exposure of said RFID device to said environment.
19 . The process of claim 17 further comprising associating an item with said RFID device such that said item and said RFID device receive comparable exposure to said environment.
20 . The process of claim 17 further comprising transmitting an interrogation signal, the characteristics of which are informed by said predetermined base frequency, in the proximity of said item.
21 . The process of claim 20 further comprising receiving said response signal from said RFID device.
22 . The process of claim 21 further comprising comparing said response signal to said predetermined base signal to produce a deviation value.
23 . The process of claim 22 further comprising utilizing said deviation value to calculate a property of said item.
24 . The process of claim 23 further comprising adjusting a use of said item based on said property of said item.
