Definitions
- reproductive outcomes significantly impact a producer's profitability.
- Negative reproductive outcomes in a breeding program impose both actual costs, such as the cost tied up in semen and veterinary technicians, and opportunity costs, such as the unavailability of inseminated animals.
- Numerous practices and products developed over the years aim to improve these reproductive outcomes.
- One particular practice focuses on identifying animal behavior corresponding to the animal's ovulation cycle. Correlating certain animal behavior to its ovulation cycle allows the producer to perform artificial insemination in a window with higher conception rates and thus better reproductive outcomes.
- Mounting behaviors present one such reliable correlation between an observable, quantifiable activity and an animal's ovulation cycle.
- monitoring the timing and frequency of mounting attempts reliably permits the determination of heat or estrus in bovids.
- artificial insemination can then be performed in a specified time frame following thereafter to improve the likelihood of conception.
- artificial insemination occurs a specified number of hours after a peak frequency of mounting attempts.
- Producers cannot always be present to monitor and quantify such behaviors.
- a significant limitation for this practice therefore, resides in its reliance on observation.
- Several developments in the field allow producers to make such problematic observations less frequently and still obtain a general idea of when the animal ovulated. However, much room for improvement remains.
- Products in the form of electronic devices are available with appropriate sensors and communication means for pinpointing the exact timing of a mounting event and relaying that information to the producer in near real time.
- Such devices require numerous electrical components to facilitate the storage, processing, and transmission of relevant data. Simply attaching such an device with all its necessary electrical components may be cost prohibitive, as the prior devices are suitable for a single use.
- Various embodiments of the present disclosure overcome certain deficiencies of the prior devices by providing a system having disposable components and reusable components.
- the disposable components are secured with the reusable components in an interlocking fashion during use. Thereafter, the components may be disengaged and a new set of disposable components can be associated with the reusable components for a subsequent use.
- certain embodiments of the present invention provide a reusable system for detection of heat or estrus.
- One embodiment provides a reusable estrus detection system having disposable components suitable for a single use and reusable components suitable for one or more uses.
- the disposable components can include an adhesive layer having a first side for attachment to a mammal and a second side and a housing mount secured to the second side of the adhesive layer.
- the reusable components can include a housing assembly releasably mounted to the housing mount and a sensor apparatus contained within the housing assembly.
- the sensor apparatus may include a power source coupled to a contact sensor for detecting contact and a transmitter for transmitting contact information.
- the contact sensor and transmitter of the reusable estrus detection system are connected through a printed board circuit assembly.
- the housing assembly includes at least one tab.
- the mounting bracket may include at least one slot that interlocks with the tab of the housing assembly to releasably secure the housing assembly to the mounting bracket.
- the housing assembly is secured to the mounting bracket with one or more clasps, hooks, or magnets.
- the contact sensor can be a switch, a pressure sensor, or a capacitance sensor.
- the housing assembly is constructed to have an angled or beveled housing side. Such embodiments eliminate corners or other surfaces that may be prone to lifting.
- a flexible material is provided in communication with the sensor apparatus.
- the flexible material may be mounted in a window formed in the housing assembly.
- the housing mount includes one or more clips for securing at least a portion of the assembly housing.
- the clip can include a movable element configured for securely receiving at least a portion of the cover.
- the sensor apparatus is configured to detect mounting attempts.
- the sensor apparatus further can include an accelerometer.
- data generated from the accelerometer can be used to verify mounting attempts detected by the contact sensor.
- the housing mount comprises a semi-rigid material that allows for bending or deflection.
- the housing assembly may be dimensioned such that the housing mount is bent or deflected to secure the housing assembly to the housing mount.
- the housing assembly can be a modular and sealed housing assembly.
- Some embodiments of the present disclosure relate to a method of detecting estrus in one or more mammals. Such methods may begin by securing a reusable estrus detection system to a mammal.
- the reusable estrus detection system having disposable components suitable for a single use and reusable components suitable for one or more uses.
- the disposable components can include an adhesive layer having a first side for attachment to a mammal and a second side and a housing mount secured to the second side of the adhesive layer.
- the reusable components can include a housing assembly releasably mounted to the housing mount and a sensor apparatus contained within the housing assembly.
- the sensor apparatus may include a power source coupled to a contact sensor for detecting contact and a transmitter for transmitting contact information.
- the reusable estrus detection system may then be operated to detect estrus in the mammal and then the reusable estrus detection system may be removed from the animal. Either following removal or prior to removal from the mammal the housing assembly may be released from the housing mount.
- the disposable components may be replaced with new disposable components including a new adhesive layer having a first side for attachment to a mammal and a second side, and a new housing mount secured to the second side of the new adhesive layer.
- the housing assembly may be releasably mounted to the new housing mount and the reusable estrus detection system may be secured to the same mammal or a different mammal with the new adhesive layer.
- the estrus detection device can be removed following the detection of estrus or insemination.

- FIG. 1 illustrates an embodiment of a reusable estrus detection system 100 mounted with a mammal 102.
- Reusable components 114 interlock with disposable components 104 secured to a bovid.
- the reusable estrus detection system 100 may be used with other mammalian species in which there is a desire to track mounting behaviors for the purpose of detecting estrus or timing artificial insemination. While the reusable estrus detection system 100 is placed near the tail, those of skill in the art will understand the device can be placed on other similar suitable locations for detecting mounting events.
- the disposable components 104 include those components suitable for a single use, or otherwise for relatively limited use. Relative to the reusable components 114, the disposable components 104 will be low cost to manufacture and easy to replace.
- the disposable components 104 include those mechanical components in direct, or nearly direct, contact with the mammal as well as with a strong adhesive for securing the entire system to the mammal.
- the reusable components 114 include those electrical components, sensors and a housing that are more expensive and which have useful lifespans greater than the time required for a single estrus detection in a mammal.
- the reusable components 114 may be contained within a modular housing for easily disengaging from an interlocking relationship with a first set of disposable components and reengaging in an interlocking relationship with a second set of disposable components. In this way the reusable components can be easily reused, thus greatly improving the utility of the device and reducing the cost per use of the overall reusable estrus detection system 100.
- FIG. 2 depicts reusable components 114 including a housing assembly 116 having at least one tab 130 extending outwardly.
- the depicted embodiment includes a first tab 103a extending outward from one side of the assembly housing 116 and a second tab 130b extending outward from the opposite side of the assembly housing.
- the disposable components 104 include an adhesive layer 106 having a first side 108 and a second side 110.
- the first side 108 is configured for firmly affixing the adhesive layer 106 to the mammal.
- a housing mount 112 is firmly affixed to the adhesive layer 106.
- the adhesive layer 106 may comprise a substrate having adhesive material, such as a glue, an epoxy, or another bonding agent, which may be applied just prior to application on a mammal 102.
- the adhesive layer 106 may comprise a one sided or two-sided tape.
- two-sided tape masking material may be applied to the second side 110 of the adhesive layer 106 in order to eliminate any undesirable adhesive surface.
- the adhesive layer 106 may be contained entirely within the boundary of the housing mount 112.
- the housing mount 112 may be affixed to the second side 110 of the adhesive layer 106 through adhesion or by other means. In another embodiment, the housing mount 112 may reside beneath the adhesive layer 106 and may extend through slots formed in the adhesive layer 106.
- the housing mount 112 depicted in FIG. 2 includes a horizontal spacing element and two vertical elements, each having a slot 132 formed thereon. The horizontal spacing element establishes a set distance between the vertical elements. This set distance corresponds to the width of the housing assembly to facilitate a force fit, or a complimentary fit between the body of the housing assembly 116 and the housing mount 112.
- the housing mount 112 provides a means for releasably securing the housing assembly 116 to the adhesive layer 106 and to the mammal 102.
- housing assembly 116 and the housing mount 112 may interlock through a force fit, complementary contact surfaces, magnets, buckles, clips, clasps or through other known means of engaging elements.
- the depicted housing assembly 116 includes at least one tab 130 for mating with at least one slot 132 of the housing mount 112.
- a first tab 130a is positioned for interlocking with a first slot 132a and a second tab 130b is positioned to interlock with a second slot 132b of the housing mount 112.
- the housing assembly 116 interlocks with the housing mount 112 when the two depicted tabs 130 are inserted through each respective corresponding slot 132. Once interlocked, the housing assembly 116 is securely engaged to the housing mount 112 and the adhesive layer 106.
- each of the tabs and slots may have varying configurations and shapes so long as they provide an interlocking means for securing the system.
- the tabs 130 and slots 132 can be dimensioned or positioned for interlocking the system in a specified orientation.
- the dimensions of one of the tabs 130 n may exceed the dimensions of all but one slot 132n, so that only the specified tab 130n can interlock with a specified slot 132n.
- the housing mount 112 could comprise at least one inward facing tab for mating with at least one slot formed in the housing assembly 116.
- FIG. 3 illustrates an exploded top view of the housing assembly 116.
- a sensor apparatus 118 in the form of a printed circuit board assembly 128 resides between a housing top 160 and a housing bottom 162.
- a first tab 130a extends from the housing bottom 162 on a first side in a first direction and a second tab 130b extends in the opposite direction.
- tabs 130, or other securing means may be formed on the housing top 160.
- the depicted housing assembly 116 together with the sensor apparatus 118 contained therein serves as the functional unit for detecting and transmitting information indicative of mounting behaviors.
- the printed circuit board assembly (“PCBA”) 128 consists of a printed circuit board (“PCB”) 186 assembled with additional electrical components that together perform the functions of the sensor apparatus 118.
- a contact sensor 122 located on the PCBA 128 provides the primary means for detecting forces representative of a mounting behavior.
- Exemplary contact sensors 122 can include switches, pressure sensors, capacitance sensors, hall effect sensors, and the like.
- the contact sensor 122 can also be a bend sensor, deflection sensor or a stain gauge properly configured with the housing assembly 116.
- a microcontroller 164 may store executable instructions for operation of the reusable estrus detection system 100, as well as information from the contact sensor 122.
- a power source 120 such as a battery, may be located on the PCBA 128 to supply power to the microcontroller 164, the contact sensor 122 as well as to other electrical components on the PCBA 128.
- a radio circuit 166 may transmit information for real time, or near real time, monitoring of animal mounting behaviors. In this way, information may be transmitted through a network and monitored or processed remotely by algorithms to determine whether a mammal is in estrus. Such algorithms and external monitoring programs may then proceed to designate a time or window for artificial insemination
- FIG. 3 depicts angled or beveled 142 housing sides 168. As but a non-limiting example the housing sides 168 may have an angle Q between 15 to 45 degrees.
- the angle or bevel 142 of the housing sides 168 reduces or even eliminates edges at the top surface of the housing assembly 116 that can be caught and lifted by the mass of second mammal such as during mounting behavior or even incidental contact between large animals.
- the angle or bevel 142 further tends to distribute forces from such mounting behaviors and incidental contact downward and horizontally. In this way forces detrimental to the secure placement and positioning of the device may be redirected into less problematic vectors. In particular, upward and horizontal forces may have a greater tendency to overcome the adhesive resulting in the displacement or removal of an estrus detection system.
- the angle or bevel 142 tends to translate forces into a downward component, which is less prone to dislodge the reusable estrus detection system 100 from a mammal 102.
- housing assembly 116 can have rounded sides or may have an overall rounded dome shape on the top and sides.
- Contact sensor 122 aligns beneath a window 146 formed in the housing top 160.
- the window 146 provides an opening covered with a flexible material 144.
- the flexible material 144 deforms under contact between mammals, such as during a mounting behavior.
- the contact sensor 122 not only aligns with the window 146, but also retains a depth positionally appropriate for contact with the flexible membrane 144.
- the contact sensor 122 may reside near the window 146 without touching the window 146, such that any deflection of the flexible membrane 144 triggers a contact event by the contact sensor 122.
- the flexible material 144 comprises a material that is transparent or semitransparent.
- An LED 180 may optionally be placed near the contact sensor 122 or in another location visible from the window 146. The LED 180 may indicate activation of the contact sensor 122 has been activated. The LED 180 may also indicate the system has been initialized, battery life status, or may otherwise convey information about the system to a user.
- FIG 4 illustrates an exploded bottom view of the housing assembly 116 comprising the housing bottom 162 a sealant 170 or boding agent the PCBA 128 and the housing top 160. From the depicted view four mounting elements 172 are visible in the housing top 160.
- the mounting elements 172 can be formed in the housing top 160, but the mounting elements 172 can also be affixed to the housing top 160 through fasteners, bonding agents, or other means. As but one example, the mounting elements 172 may comprise fasteners themselves inserted through the exterior of the housing top 160.
- Mounting holes 174 formed on the PCBA 128 are spaced and dimensioned to receive the mounting elements 172 connected to the mounting top 160.
- a plastic face may be incorporated in order to limit the upward movement of the PCBA 128 within the housing.
- the mounting elements 172 mate with mounting holes 174 to hold the PCBA 128 in a fixed location relative to the housing top 160. This position will, for example, align the contact sensor 122 with the flexible material 144.
- Those of skill in the art will appreciate numerous forms that may be molded in the housing top 160 as mounting elements 172, or which may be added by welding, fasting or other means for the purpose of enclosing a housing.
- the configuration of the mounting elements 172 and the mounting holes 174 may also position the PCBA 128 and the contact sensor 122 at an appropriate depth relative to the flexible material so that the contact sensor 122 is triggered when a second animal attempts to mount the first animal.
- the contact sensor 122 may be positioned directly in contact with the flexible material 144.
- the contact sensor 122 may be located some set distance from the flexible material 144. In such embodiments establishing a set distance, or depth, may reduce false positive signals which may be produced in response to incidental or glancing contact that is not indicative of a mounting behavior.
- Those of skill in the art can determine suitable distances by balancing reducing false positives caused by non-mounting contact of the flexible membrane with the desire not to miss events likely to be caused if mounting activity
- the housing bottom 162 may be affixed to the housing top 160 with a sealant 170 to ensure that the housing assembly 112 remains water resistant.
- the housing bottom 162 may be bonded to the housing top 160 with a glue, a bonding agent, epoxy, or through sonic welding.
- the housing top 160 and the housing bottom 162 may be secured together with fasteners.
- Such an embodiment may also include a gasket or seal to ensure that the housing assembly 116 remains water resistant.
- it is desirable that the electronics are protected from moisture, such as condensation, precipitation and perhaps even splashing or licking by other animals.
- FIG. 5 depicts a side view of the reusable estrus detection system 100.
- the disposable components 104 are aligned with, but not interlocked with, the reusable components 114.
- a housing bottom 162 includes two tabs 130a, b for interlocking with the slots 132a, b of the housing mount 112.
- the contact sensor 122 and power source 120 are mounted to the PCB 186 in the housing assembly 116.
- a small gap exists between the contact sensor 122 and the flexible material 144 so that any deformation activates the contact sensor 122.
- an intermediate material may be placed between the flexible barrier and the contact sensor 122.
- Those of skill in the art can appreciate other sensors may be used to detect deflection of the flexible material 144.
- the contact sensor 122 can be replaced with a deflection sensor, a bend sensor, a pressure sensor, a capacitance sensor, a stain gage, a time of flight sensor, or an appropriately configured hall effect sensor.
- the hall effect sensor may be placed in the same location as the contact sensor 122 on the PCBA 128 and the flexible material 144 could be modified with the addition of a magnet. The distance between the magnet and the hall effect sensor would be set such that any deflection of the flexible material 144 representative of a mounting behavior places the magnetic field of the magnet within range of the hall effect sensor.
- those sensors may be bonded to the flexible material 144 such that deflection indicative of mounting behavior would register as a detected. Still other sensors may be readily employed to detect deflection of the flexible material 144 in configurations known to those of skill in the art.
- Disposable components 104 including the adhesive layer 106 and the housing mount 112 are depicted below the reusable components 114 substantially aligned for an interlocking configuration.
- a deflection range 182 for the housing mount 112 indicates an exemplary deflection range for the housing mount 112. Deflecting the housing mount 112 may facilitate a two-step interlocking engagement between the housing assembly 116 and the housing mount 112.
- the housing mount 112 may be constructed from a semi rigid material to facilitate this deflection, such as ABS, poly propylene, or a suitable thermoform plastic.
- the two-step interlocking engagement may begin with inserting first tab 130a of the housing assembly 116 into corresponding first slot 132a in the housing mount 112. Next, applying an upward force in the center of the housing mount 112 introduces a deflection 182 and the second tab 130b can be inserted into its corresponding second slot 132b. Thereafter removing the deflection 182 in the housing mount 112 causes the housing assembly 116, and specifically the housing bottom 162, to sit flush against the housing mount 112 with each tab 130 to fully engaged in each respective slot 132.
- housing mount 112 and the housing assembly 116 are securely interlocked and cannot be disengaged by a lateral motion or force, such as the forces caused by one animal sliding down off the back of the animal to which the device is affixed.
- IB may remove the housing assembly 116 by reintroducing the deflection 182 into the housing mount 112 and then removing a one tab 130 from its corresponding slot 132. Once a first tab 130 has been removed, the housing assembly 116 can slip free of the remaining slot 132. Following removal of the housing assembly 116, that housing mount 112 remains affixed to the mammal 102 and can be removed later and discarded.
- FIG. 6 illustrates the PCBA 128 in accordance with embodiments of the invention.
- the PCBA 128 serves as the sensor apparatus 118 and includes electric components mounted on a printed circuit board 186 for the purpose of generating a signal containing information indicative of mounting behaviors.

- the power source 120 provides energy for operating the other active electrical components contained within the housing assembly 116.
- the power source 120 may comprise a rechargeable power source, a photovoltaic element, a chemical battery, a super capacitor, a fuel cell, a mechanical energy harvest system, or even combinations thereof.
- microcontroller 176 includes a microprocessor and other integrated components for executing instructions and manipulating or storing data from various peripheral components.
- Exemplary peripherals contained on the printed circuit board 186 include a contact sensor 122 illustrated in the form of a switch 136, and a transmitter 124 which may be a radio circuit 184.
- an LED 180 and additional sensor 190 such as a motion sensor or an accelerometer 152, may also be mounted with the PCB 186. Data from the additional sensor 190 may be evaluated along with data from the contact sensor 122 in order to determine mounting behaviors and determine the onset of estrus.
- additional sensor 190 may incorporate one or more sensor components or subsystems to determine motion, acceleration, orientation, temperature, light, sound, location including global positioning, (ruminant) pH, chemical or biochemical status, electromagnetic signal or a combination of any of these variables. Data from such various sensors can be combined and evaluated with weighting functions or other mathematical functions and algorithms to improve the accuracy and reliability of measurements.

- the disposable components 204 may comprise those low cost and easily replaceable components primarily associated with securing the reusable components 214 to a mammal, such as a bovid 202.
- the reusable estrus detection system 200 may have a generally circular footprint. Such a circular footprint may be advantageous in that vertical edges and corners are eliminated that can present contact points susceptible to snagging or otherwise being easily lifted or moved from its position on the mammal. For this reason, the round shape may better help and better secure the reusable estrus detection system 200 to a larger mammal.
- the housing assembly 216 may have a beveled or curved side surface 242.
- the beveled or curved side surface 242 eliminates horizontal edges that could also be caught or snagged and displaced by the interaction of two large mammals, such as mounting behavior.
- a flexible material 244 may comprise an entire top surface of the housing assembly 216. Such an embodiment presents a greater contact surface area for detecting mounting behaviors. Further, the system 200 may be less dependent on precise location and orientation on the bovid 202 to reliably detect mounting behaviors.
- an embodiment of the reusable estrus detection system 200 includes disposable components 204 including housing mount 212 in the form of a flat disposable plate having a first tab 230 a and a second tab 230 b formed thereon.
- the housing mount 212 may be formed from a plastic, rubber, or other sufficiently rigid material for interlocking with the housing assembly 216.
- the reusable components 214 including the housing assembly 216 and the sensor apparatus 218 are depicted in relative alignment with respect to the disposable components 204.
- the housing mount 212 and the tabs 230 are constructed from a material sufficiently rigid and non-deformable to resist deformation under the weight of a bovid. At the same time, the material should be flexible enough for the tabs 230 to bend slightly as they engage with slots 23,2a, b formed in the housing assembly 216. In such an embodiment the tabs 230 may be formed as clips 248 for holding the housing assembly 216 firmly in place against the housing mount 212.
- other interlocking mechanisms such as clasps, hooks, magnets, fasteners or even a threaded engagement may serve a similar function. While FIG. 8 illustrates two such tabs and slots, those of skill in the art will appreciate 1, 3, 5, 6, or even more pairs of tabs and slots could also be used.
- the exterior of the housing assembly 216 may be formed from a plastic such as polyvinyl chloride (PVC), polyethylene (PE), nylon, or acrylonitrile butadiene styrene (ABS).
- the flexible material 244 located at the top of the housing assembly 216 may be constructed from the same or a different material as compared to the housing assembly 216.
- the contact point for the contact sensor will be higher than the top portion of the tabs 230, so that the tabs 230 do not interfere with the downward deflection of the flexible material 244 during a mounting activity.
- the contact point of the contact sensor may be lower than the top portion of the tabs 230. In such an embodiment, the tabs may serve to guard the contact sensor from being triggered by glancing or incidental contact.
- FIG. 8 partially reveals a sensor apparatus 218 comprising a printed circuit board assembly 228.
- a power source 220 such as a battery
- a microcontroller 276 sit on a printed circuit board 286.
- Other peripheral components obstructed from view include a contact sensor, a portion of which would touch or align just beneath the flexible material 244 formed in a top portion of the housing assembly 216.
- the contact sensor could be a mechanical switch, a pressure sensor, a capacitance sensor, a stain gage, a deflection or bend sensor, a time of flight sensor or an appropriately configured hall effect sensor.
- the flexible material 244 may comprise a plastic sufficiently pliable for deformation under the weight of a mounting behavior.
- suitable plastics may include: a plastic such as polyvinyl chloride (PVC), polyethylene (PE), nylon, or acrylonitrile butadiene styrene (ABS).
- PVC polyvinyl chloride
- PE polyethylene
- ABS acrylonitrile butadiene styrene
- Suitable materials can also include a rubber, metal, or other composite, so long as the material is capable of elastic deformation in a manner that triggers the contact sensor.
- FIG. 9 depicts an exploded bottom view of the reusable estrus detection system 200 having essentially the same elements illustrated in FIGS. 7 and 8.
- the adhesive layer 206 is secured to the bottom of the housing assembly 212. From the bottom view the mounting holes 274 can be seen in the printed circuit board 286 for matching with the mounting elements 272 formed in the housing assembly 212.
