Aspects of the present invention relate to an apparatus and a method of determining when a cow may be in oestrus (in-heat), or when the cow is about to calve. The method comprises monitoring movement of the cow using a motion sensor or sensors attached to the cow. The method further comprises determining a mathematical function of the movement pattern of the cow based on the monitored movement of the cow over a period of time, and determining when the cow is in heat or about to calve by analysing and comparing the mathematical function to threshold values which are adjustable by a machine-learning self-adjusting algorithm.

Animal transmitters are provided that can include: a transducer configured to transmit a signal; process circuitry coupled to the transducer; and an energy harvesting element coupled to the process circuitry. Animals having a transmitter coupled thereto are also provided with the transmitter including an energy harvesting element in operational alignment with the animal's musculoskeletal system. Methods for transmitting the location of an animal are also provided with the methods including: coupling a transmitter powered by an energy harvesting element to the animal; and monitoring the transmissions of the transmitter.

A durable pet tag having machine readable indicia. A multiple layer label is pre-assembled and applied and embedded into a metal substrate for durability. A two sided pet tag having machine readable indicia on a first side and human readable indicia on a second side is provided, the human readable indicia being stamped into the side of the substrate opposite the machine readable printed sheet so that a single pet tag is provided with machine readable data to allow finders of lost pets to retrieve owner information using a smart phone and the database accessible with the pet tag machine readable indicia. The pet tag also has human readable indicia to comply with legal requirements.

A pet door system is provided including a casing configured to attach the pet door system to a building and a flexible door attached to the casing. In some embodiments, the door is segmented and comprises a plurality of interlocking segments that are rotatable with respect to each other. In some embodiments, the pet door system further includes a rotating cylinder attached to the flexible door and rotatably connected to the casing and a motor comprising a gear head, where the gear head is attached to the rotating cylinder, such that when the motor is activated, the gear head is rotatable in a first direction to wind the flexible door around the rotating cylinder. In some embodiments, the pet door system may be operated by a pet-worn collar and/or may be remotely controlled via a mobile device.

A method and a system configured to differentially direct the passage of livestock animal; to signal the livestock animal; to identify an individual livestock animal and to monitor livestock activity are provided.

A system and method for identifying a service animal, include an identification device associated with the service animal. The identification device identifies the service animal. The identification device includes a storage medium that stores service animal profile data that includes information identifying the service animal. The service animal profile data is configured to be analyzed by an admission sub-system to confirm an identify of the service animal.

An apparatus for farming animals, with a trough, a distributing system, an identifying system, a database and a control unit that allows, once an animal has been identified, the time passed ‘t’ since the time T.sub.0 corresponding to the last feed of said animal to be measured, a new value of the credit feed weight MC to be computed with the formula

[00001]$\mathrm{MC}\left(t\right)=\frac{MP}{\Delta T}*\left(t-T_0\right)+M{C}_0$

and a succession of feed portions to be distributed to the trough until the animal is sated or until a zero or negative credit feed weight MC is obtained.

In one aspect, a pet access apparatus including an actuator and a pet door movable between a closed position and an open position. The pet access apparatus includes communication circuitry to receive a signal indicative of proximity of a pet to the pet door. The pet access apparatus includes an interior camera, an exterior camera, and a processor operably coupled to the actuator, the communication circuitry, the interior camera, and the exterior camera. The processor is configured to determine an attempt by the pet to operate the pet door based at least in part on the proximity of the pet to the pet door, the interior image data, and the exterior image data. The processor is further configured to facilitate movement of the pet door from the closed position toward the open position upon the determination of the attempt by the pet to operate the pet door.

Techniques and examples pertaining to a tracking method using a two-component tracking device are described. The tracking device includes two components paired with one another: a first component that is specific to a subject the tracking device is intended to track, and a second component that is generic. The second component is capable of establishing a wireless connection with a cellular network, as well as collecting location information of the second component itself. The tracking method involves receiving from the cellular network a set of requirements associated with the subject, and triggering an action based on the set of requirements and the location information collected. The tracking method enables tracking of multiple subjects without a pairing mistake. Namely, a mismatch between multiple subjects to be tracked and multiple tracking devices intended to track the subjects can be avoided.
