The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of said present invention, since the scope of said present invention is best defined by the appended claims. 
         [0030]    The present invention is a real time measuring device  100  according to one embodiment of the present invention is schematically shown in  FIG. 1  and  FIG. 8 , when mounted on a mother&#39;s breast for a pediatric nourishment feeding session. According to this embodiment, the device comprises a cover cap  101  that is fashioned to effectively match a woman&#39;s breast and having a cannula and nipple region  102  with a nipple tip end with a small opening  102   n  for fluid exiting. Said cannula  102  is a hollow duct chamber region that upon continuous or sporadic ejection of nourishment fluid flow is the carrier for said nourishment fluid from a mother&#39;s breast to a pediatric recipient&#39;s mouth. Said flow path for a pediatric feeding session begins from the mother&#39;s breast that has said cover cap  101  mounted. 
         [0031]      FIG. 2  shows that said cover cap  101  is in communication with embedded cylindrical electrical capacitor member means region  110  of the overall cannula, which is in communication with cannula member means region  102 . Said cylindrical electrical capacitor member means  110  is embedded in between a silicone encapsulated contiguous stratum comprising the overall enclosure composition element according to one embodiment of the present invention. In  FIG. 2  fluid entry from a mother&#39;s breast nipple enters the hole  111  of said cannula  110  and  102  and travels in a longitudinal flow through said cannula  102  on through to nipple exit hole  102   n .  FIG. 2  shows said piezo-resistive toroid member means  103  that is embedded in between a silicone encapsulated contiguous stratum comprising the overall enclosure composition element according to one embodiment of the present invention, and in communication with nipple region  102 . Said toroid piezo-resistive member means  103  and said cylindrical electrical capacitor member means  110  are electrically connected and in communication with embedded system microcontroller circuit  106  by embedded etched circuit connection wires  109 . Further, said embedded microcontroller circuit  106  is in communication with input/output port points  107 . Said input/output ports  107  in  FIG. 2  are utilized as a means of communication for data downloading and uploading. For sturdiness and long product lifetime, a strong and flexible cable support member means  105 , capable of bending is utilized as a support means for the hard wired connections of cable  108  that connects to a monitor enclosure  200  that is shown in  FIG. 8  that utilizes a connection plug  115 .

         [0033]      FIG. 4  shows a modified toroid air filled soft buffer comfort aid member means  104  with opening  104 R that slips over the cannula region  110  and is positioned between and in communication with cover cap  101  and piezo-resistive toroid member means  103 . Said modified toroid air filled soft buffer comfort aid member means  104  is a removable member means that is utilized for an infant&#39;s comfort and relaxation during a feeding session by allowing the infant to feel something soft as a mother&#39;s breast, since the actual mother&#39;s breast is out of communication with said infant. 
         [0034]      FIG. 5  shows showing a front view with six input/output ports  107  all, that are utilized for the uploading or downloading of data entry or collection for external feeding history. 
         [0035]      FIG. 6  shows the rear view as it would be applied onto a mother&#39;s breast. 
         [0036]      FIG. 7  shows comprehensive views of said flexible etched printed circuit member means comprising; microcontroller circuit  106 , connecting flat wire interconnect cable  109 , cylindrical electrical capacitor member means region  110  that forms a hollow tubular hole  111 , and piezo-resistive toroid member means is embedded in between a polyimide encapsulated contiguous stratum comprising the overall enclosure composition element according to one embodiment of the present invention. Said cylindrical electrical capacitor member means region  110  that forms a hollow tubular hole  111  is comprised of two thin copper metal bands  113  that surround the circumference of said cylinder form, and said flexible etched printed circuit member means comprising; microcontroller circuit  106 , connecting flat wire interconnect cable  109 , cylindrical electrical capacitor member means region  110  that forms a hollow tubular conduit  111 , and piezo-resistive toroid member means is encapsulated in a silicone encapsulate  112 . 
         [0037]      FIG. 8  shows the present invention  100  connected to its monitor enclosure  200 . Said monitor enclosure  200  is comprised of a front alphanumeric display member means  201 , an arrangement of a plurality of alphanumeric digital segment member means; for left breast flow monitor readout  201 LF, a left breast volume monitor readout  201 LV, a right breast flow monitor readout  201 RF, and a right breast volume monitor readout  201 RV. The left breast control button switch member means  202 L toggles between left breast flow and volume, the right breast button switch member means  202 R toggles between right breast flow and volume, and total accumulation button switch  203  is utilized for totaling a selected channel for any session feeding. The monitor  200  has an off/on button switch member means  204  on the front of said monitor enclosure. 
         [0038]      FIG. 9  is illustrative of an instance where said present invention  100  is placed over a mother&#39;s breast  300  and associated nipple  301 . Utilizing said present invention  100  shown in  FIG. 1  and  FIG. 8 , a feeding session begins with a calibration sequence, whereby a mother operated said monitor console  200  and presses either or both of said calibrate push button switches  202 L for a left breast feeding and  202 R for a right breast feeding. During this time of calibration said microcontroller member means  106  receives an initial frequency output from said hysteretic astable oscillator member means  400  as shown in  FIG. 11 . This initial reading is stored and represents a value of the dielectric constant between said plate bands  113  of passive cylindrical capacitor member means  110 , before a mother&#39;s breast is inserted in cover cap  101 . Ergo, the initial intrinsic dielectric constant is that of air. Meanwhile when a mother inserts one of her breasts, either left or right, into said cover cap member means  101  she presses said appropriate push button switch either left switch  202 L or right switch  202 R. As said breast enters, and is in place, said dielectric constant value of said cannula region member means  110 , that houses said embedded passive cylindrical plate bands, increases because the dielectric constant of human tissue and milk is much greater than air. There are three dielectric constant conditions to consider associated with said passive cylindrical capacitor member means  110  and plate band member means  113 ; (1) when no breast or milk exists in said cannula region, (2) when a mother&#39;s breast is inserted in device and no lactation begins, so that there is only air plus a breast, and (3) when lactation begins and there is a mother&#39;s breast plus a volume  304  of milk fluid that exists in said cannula regions  110  and  102 . These three different conditions result in three different dielectric constant values to be registered and used in flow and volume calculations by said microcontroller  106 . 
         [0039]    As illustrated in  FIG. 10 , when an infant begins sucking on nipple region  102  of said present invention  100 , the mother starts lactating and her breast milk flows into said cannula region which is in part capacitor region  110  and nipple reservoir  102 , where it exits at nipple orifice  102   n  and enters said infant&#39;s mouth as said infant clamps down on said nipple region  102  with its upper lip  303 U and its lower lip  303 L. All during said feeding session, where mother is lactating and milk is flowing, said capacitance value registers as a fluid presence condition in said microcontroller  106 , and as said infant continues to feed as shown in  FIG. 10  said infants lips  303 U and  303 L clamp down on a section of said cannula region  102 , where therein exists a captured small volume  306  of milk fluid  305 . Through precise and accurate programming algorithms, flow rate and volume of milk fluid consumed over time is calculated by said microcontroller  106 . 
         [0040]    For said passive cylindrical capacitor member means  110  comprised of plate band member means  113  that determines the presence of a breast and milk fluid volume, said capacitance value is mathematically determined by equation

         [0000]    Where f r     1    is the resonant frequency of flow oscillator  400  and the dielectric constant k relates to that volume of space occupied in said cannula region  110  within said capacitor plate bands  113 , and changes against a calibrated value of air when a breast is inserted, and when a breast is inserted and lactation begins and milk fluid fills said cannula region  110  within said capacitor plate bands  113 . It should be obvious to anyone steeped in the art that f r     1    is inversely proportional to dielectric constant k, and that k is determined by conditions within said cannula region  110  that contains capacitor plate bands  113 . Ergo, whenever said dielectric constant k changes due to changes from an air only condition to a breast entry only and further a breast entry plus milk fluid entry condition, the resonant frequency of said flow oscillator  400  will change, i.e. as the dielectric constant k increases when a breast and milk fluid enter said cannula region  110 , the resonant frequency of flow oscillator  400  will decrease.

         [0049]    Where f r     2    is the resonant frequency of volume oscillator  500  and R p  is the resistance value of toroid piezo-resistive member means  103 . The design operating characteristics of said FlexiForce® piezo-resistive thin film embodiment or similar flexible piezo-resistive thin film embodiment  103  is such that whenever a deformation is created from the force of an infant  302  sucking on said nipple member means  102  by upper lip  303 U and lower lip  303 L, the value of resistance R p  of said FlexiForce® piezo-resistive thin film member means or similar flexible piezo-resistive thin film member means  103  decreases. Being that the resonant frequency f r     2    of volume oscillator  500  is inversely proportional to the resistance R p    
         [0050]    As said infant  302  periodically sucks on nipple region  102 , that contains said volume of milk fluid V 2  that is continuously pulled through volume V 1 , said FlexiForce® piezo-resistive thin film member means or similar flexible piezo-resistive thin film member means  103  deforms as shown in  FIG. 10  by a distance of d v  and said deformation bends toward the lactating mother. This to and fro action and deformation movement causes the resonant frequency of volume oscillator  500  to increase and decrease in frequency respectively, thus providing data to said microcontroller  106  for constant updating of volume consumed information that is made available for reading on said monitor console  200 . 
         [0051]      FIG. 12 , shows a flow chart for one embodiment of the present invention&#39;s system operational algorithm set  600 , which is the same for either said left breast data channel embodiment and said right breast data channel embodiment. Said algorithm flow begins at start either for said left or right channel  601 , and said start point  601  is when this embodiment of the present invention  100  is fitted on a mother&#39;s breast and a host presses either said left breast channel operate button switch  202 L or right breast channel operate button switch  202 R. The next sequential logic decision making step  602  waits for said cannula  110  and  102  in  FIG. 9  to filled with breast milk fluid volume V T ; this event takes place when said infant  302  in  FIG. 10  commences to suck on said nipple region  102   n  of cannula section  102 . Said event causes breast milk fluid to cause a shift in resonant frequency of flow oscillator  400  as shown in  FIG. 11 . A coefficient (d+2πr) distance d c  is used in eq. 3 and said center resonant frequency f r  of flow oscillator  400  deviates from center frequency downward to a lower frequency when a breast enters said cannula  110  region with plate bands  113  in  FIG. 9  and  FIG. 10 ; when said breast starts lactating said cannula  110  is filled with breast milk fluid and said center resonant frequency of said flow oscillator  400  of  FIG. 11  deviates a second time further decreasing said frequency downward shift. This allows for said decision making step  602  to advance to the next logic decision making step to determine if said infant is sucking, thus causing said toroid embodiment  103  to deform and move in a direction towards said breast  300  as said infant  302  sucks and pulls on nipple region  102  to extract and consume continuously or sporadically, a small volume V 2  of breast milk fluid. If there is no deformation of toroid  103 , the microcontroller waits for said presence of deformation signals generated by toroid  103 . Upon receiving said signals form toroid, a flag signal enables a counter decision  604  to count consumption volume instantly consumed by said infant  302  and said value count is displayed, by display enable  605 , on either said left flow display region  201 LF, left display volume region  201 LV or said right flow display region  201 RF, right display volume region  201 RV. Simultaneously, system program subset calculates a total feeding session history of volume consumed  606  and if a total count is not requested by host, said volume count continues; when host presses total volume button switch  203 , that value accumulated is registered for storage and future use and displayed  607 .
