    APPARATUS AND METHOD OF DANE DETECTION PRODUCED BY THE MIOPATIA OF THE DEEP PECTORAL IN BIRDS
    OBJECT OF THE INVENTION
    The present invention aims to address a problem that occurs frequently in birds for human consumption, especially those raised on farms, specifically the problem of the myopathy of the deep pectoral (DPM).
    The object of the present invention relates to an apparatus and method for detecting damage caused by myopaths in the breastplate, or commonly called breast, of birds slaughtered for human consumption.
    BACKGROUND OF THE INVENTION
    Currently, bird production has continued in its upward trend in recent years. This increase in the production of the poultry sector has been possible through strong technification, professionalization and intensification of the sector, as well! as an increase in genetic selection to achieve a higher growth rate.
    However, this intensification of the poultry sector has led to an increase in the myopathy of the deep pectoral, mainly in chickens and turkeys with hypertrophic musculature. In the case of these birds, a multitude of causes have been described that can cause myopathy of the deep pectoral, from respiratory diseases on farms, to phenomena caused by stress of the animal, such as the moments before slaughter.
    The myopathy of the deep pectoral, commonly known as green muscle disease, or Oregon disease, mainly affects the internal pectoral muscles, close to the heart of the bird, found for the first time in adult turkeys, later in adult broilers, and finally in young broilers.

    More specifically, myopathy in a rupture of muscle tissue accompanied by internal bleeding that can lead to necrosis or muscular infarction at its most critical levels. Because it is an interaction between the heart and the adjacent muscle, the affected meat belongs mainly to the tenderloins of the bird, that is, of the supracoracoid or pectoralis minor muscles (internal pectoral muscle).
    Recently a change in the pattern of consumption has been detected, and more and more whole chickens are demanded, or in large pieces, and it is in this case that the problem is rarely detected. Therefore, it is only visually detectable by specialized personnel present in the slaughterhouses, during the pectoral extraction. Consequently, with the current detection system, if the breastplate is removed, its low quality and its poor visual appearance cannot be appreciated, with the consequent complaints of the consumer, and the bad image that this gives to the producers.
    DESCRIPTION OF THE INVENTION
    The present invention allows detecting, from the permittivity, the structural and biochemical alterations caused by myopathy of the deep pectoral in birds and selecting the birds, or parts thereof, suitable for human consumption.
    It should be noted that permittivity is the physical property that describes the interactions of an electric field on the medium in which it propagates.
    In the present invention the permittivity in the range between 100 Hz and 1 MHz has been obtained, a range that shows two dispersions or interactions of the photons with the medium (alpha and beta). Each of these two dispersions refers to different chemical species. Both alpha and beta dispersion allow the identification and quantification of chemical species involved in hemorrhage and / or ischemic processes, using this information in the detection of myopathy damage through algorithms and decision trees implemented by the invention.
    More specifically, the alpha dispersion, also called counterion, is induced by
    5
    10
    fifteen
    twenty
    25
    30
    the orientation of mobile charges in the dielectric medium. While the beta dispersion describes the interactions with fixed or low mobility loads found in the dielectric medium.
    Specifically, the present invention consists of an apparatus comprising a control unit linked to a conditioning device, which through a multiple transducer sensor applies a voltage difference between transducers inducing an electric field between them, through the medium dielectric, in a variable frequency range and at different levels of penetration, on the pectoral of the bird to obtain the permittivity of the pectoral.
    Said multiple transducer sensor comprises a base, of substantially curved or flat configuration, with a plurality of transducers that allow the electrical signal to be applied to the bird's breastplate and to receive the response signal from the bird's breastplate.
    This multiple transducer sensor is linked to the conditioning device that comprises mechanisms for adapting both signals, that is the generated electrical signal and the response signal. This conditioning device also comprises a signal generator, which generates said electrical signal which is a signal of the sine type with an instantaneous frequency comprised between 100 Hz and 1 MHz that varies linearly with time, this scanning time being less than 100 ms . As for the response signal, it is obtained from the multiple transducer sensor and is transferred to the control unit for processing and from the electric field generated between the transducers and with the known geometry and separation, the permittivity is obtained.
    On the other hand, the control unit comprises a microprocessor integrated in a programmable device linked to a data acquisition system and with said device the permittivity is obtained as a function of the frequency.
    More specifically, the control unit allows starting from the permittivity as a function of the frequency, and by means of a logistic algorithm obtaining the alpha and / or beta dispersions of the permittivity. From the dispersions obtained from the pectoral of the bird at two levels

    of penetration, together with the variable post-mortem time, this being considered as the time elapsed since the bird was sacrificed, the presence of myopathy is known, or not, in the bird's breastplate.
    This represents a great advantage because the damage caused by the myopathy of the deep pectoral affects the pectoralis minor muscle (internal pectoral muscle) and to a lesser extent the pectoralis major (external pectoral muscle) of the bird. Thanks to this invention, birds can be selected and classified in different categories according to the level of damage caused. These categories are: pectoral not damaged, pectoral with hemorrhagic damage and pectoral with necrosis. It can also be indicated if the damage has reached pectoralis major and pectoralis minor or only pectoralis minor of the bird.
    In this way the birds that present pectoral with hemorrhagic damage and / or with necrosis can be destined for their bone and so on! avoid waste of some of the most valuable parts of the bird.
    Optionally, the control unit is provided with connection means intended to be coupled with an automatic device for classifying and / or eliminating birds with damage caused by myopaths. This automation increases productivity and speed in the classification.
    Additionally, said control unit is provided with communication means intended to be coupled to at least one data processing unit external to the apparatus, such as a personal computer, Tablet or Smartphone, improving the man-machine interface, and allowing for example device monitoring remotely.
    The method of detecting the damage produced by myopaths in the bird breastplate is applied to the bird's carcass, manually or automatically, and includes:
    - place the sensor of multiple transducers of known dimensions and separation on the bird housing, so that said transducers come into contact with the bird's skin,

    - generate an electrical signal, in a frequency range by means of a generator integrated in the measurement system. linked to said multiple transducer sensor,
    - adapt the electrical signal generated by means of adaptation mechanisms integrated in the conditioning device, to transfer it to the multiple transducer sensor,
    - apply, in the bird's housing, said electrical signal inducing electric fields at different levels of penetration by means of the multiple transducer sensor,
    - receiving, the response signal from the bird's pectoral by means of said multiple transducer sensor to transfer it to the conditioning device,
    - adapt the response signal by means of the adaptation mechanisms integrated in the conditioning device.
    - transfer the appropriate response signal to a control unit linked to said conditioning device,
    - process the data through the control unit,
    - calculate the permittivity based on the frequency from the signal obtained, the surface and separation of the transducers
    - obtain the dispersion values by means of a logistic algorithm
    - Apply predictive models based on dispersion values, different levels of penetration and postmortem time.
    - determine myopathic damage, based on the results of the predictive models.
    The generated electrical signal is a sine wave signal with an instantaneous frequency that varies linearly with time and is between 100 Hz and 1 MHz. The scan time between the minimum and maximum frequency will be less than 100 ms.
    More specifically, for the control unit to detect myopathic damage, it is necessary to know the post-mortem time of the bird. This post-mortem time may have been manually entered into the control unit before or during myopathic damage detection individually for each bird or more generally for a group of birds. Additionally this may be preset in the

    control unit.
    In this way the structural state of the meat and therefore the conformational changes derived from hemorrhages and necrosis can be determined. Because associated with the usual maturation processes in meat, there are also quantifiable changes in the dielectric spectrum, the inclusion of postmortem time is important, to differentiate between maturation and myopaths.

    PREFERRED EMBODIMENT OF THE INVENTION
    In a preferred embodiment of the invention, as shown in Figure 1, the apparatus (1) comprises a control unit (2) connected with a conditioning device (3), which through a multiple transducer sensor (4), applicable on the breastplate (5) of the bird, obtains the permittivity of the breastplate (5).
    Said multiple transducer sensor (4) allows to apply, through a plurality of transducers, an electrical signal on the breastplate (5) of the bird and receive a response signal (5) to transfer it to the conditioning device (3).

    This conditioning device (3) comprises a signal generator (6) connected with signal adaptation mechanisms (7), which allow the conditioning device (3) to be linked with both the multiple transducer sensor (4) and to the control unit (2).
    Also, in Figure 1, it is schematically observed that the control unit (2) mainly comprises a microprocessor integrated in a programmable device (8) linked to a data acquisition system (9), which receives the data from the signal of pectoral response (5) adequate by said signal adaptation mechanisms (7).
    The data acquisition system (9) is based on an SOC (System On Chip) platform that allows communication with a data processing unit external to the apparatus (1) described in this invention, such as a personal computer (10) , through an ethernet type connection. From this computer it is possible to enter a post-mortem time of the bird or group of birds to which the myopathic damage is going to be detected. This computer also allows the monitoring of the detection process in real time and from any point with internet access.
    The programmable device (8) is of the FPGA (Field Programmable Gate Array) type. Specifically, this programmable device (8) receives the data from the pectoral response signal (5) through said data acquisition system (9). Additionally, the programmable device (8) implements a first signal processing, which allows obtaining the permittivity as a function of the frequency, a second analysis by means of a logistic algorithm to obtain the dispersions and a third predictive algorithm that allows the detection and quantification of the chemical species involved in the damage caused by myopaths.
    With the quantified value of said chemical species (lactic acid or the level of structural proteins) at different levels of depth and the postmortem time value of the bird, by means of the programmable device (8) comprising another algorithm that calculates the metabolism of maturation, maturation in hemorrhagic tissue and the process of cellular ischemia, the level of myopathy of the

    deep pectoral This level of myopathy of the deep pectoral is classified according to the categories: Cat. 0 corresponding to the pectoral (5) not damaged, Cat. 1 pectoral (5) with hemorrhages, and Cat. 2 pectoral (5) with necrosis.
    More specifically, to perform the detection of the damage in the breastplate (5), the control unit (2) obtains the permittivity value as a function of the frequency by processing the signal in reduced blocks and sequentially based on the application of the Wiener-Khinchin theorem.
    More specifically, in figures 2 and 3 the experimental permittivity data used in a non-limiting manner in the present invention is shown as a reference to know the status of the pectoral (5) of the bird. Figure 2 shows the concentration of lactic acid with respect to the dielectric constant in the alpha dispersion corresponding to each of the categories, while Figure 3 shows the concentration of myosin, collagen and sarcoplasmic proteins, as well as actin corresponding to each category with respect to the frequency of beta dispersion.
    This shows the prediction capacity of lactic acid and structural proteins by means of alpha and beta dispersions.
    More specifically regarding the multiple transducer sensor (4), its configuration can be seen in more detail in Figure 4. This presents a base, of substantially curved configuration, with a plurality of transducers (11) for injecting said electrical signal, generated by the signal generator (6), at various depths of the breastplate (5), and receiving the response signal from the pectoral (5) of the bird. Additionally, the sensor of multiple transducers (4) is capable of varying the separation between said transducers (11), as well as its geometry, managing to penetrate at different depths of the breastplate (5) of the bird.
    In this way, the myopaths can be classified in birds, for each part of the pectoral, that is, for its pectoralis major (12), and for its pectoralis minor (13), depending on its level of damage: undamaged, hemorrhagic damage and necrosis.
    In another preferred embodiment, not shown, the data processing unit is a
    tablet or smartphone
    In another preferred embodiment, not shown, the multiple transducer sensor comprises a base with a plurality of flat transducers.
    In another preferred embodiment, not shown, the programmable device is linked to an automatic bird separation device with damage caused by myopaths in the breastplate. This connection is made by means of connection of the control unit intended to be coupled with said automatic means. These automatic means 10 allow the birds to be separated with the damaged breastplate from the birds that do not have it, totally autonomous.
