A method for manufacturing an electronic apparatus functioning as a component of a wireless communication system includes providing a lower part formed with a first concave portion, a second concave portion spaced away from the first concave portion, and a third concave portion which couples the first concave portion and the second concave portion, providing an upper part for sealing the first concave portion, the second concave portion, and the third concave portion formed in the lower part, providing a module unit including a sensor which detects a physical quantity, and a radio communication unit which transmits data based on an output signal from the sensor, providing a battery for supplying power to the module unit, coupling the module unit and the battery by a wiring, and after the coupling the module unit and the battery, arranging the module unit in the first concave portion of the lower part.

A disease management method and apparatuses performing the disease management method are disclosed. The disease management method may include receiving bioinformation of a cow from a biosensor capsule provided in a stomach of the cow, determining a health state of the cow by analyzing the received bioinformation, and transmitting information associated with the determined health state to a user who manages the cow, in which the health state may include at least one of a breeding-related state associated with estrus and delivery of the cow, a disease state of the cow, a methane gas generation state of the cow, or a rumen activity state of the cow.

An electronic apparatus is provided which, even when the electronic apparatus configuring a node is implanted in the body of an object animal, makes the object animal hard to feel stress and can acquire effective data about the natural behavior and state of the object animal. As shown in FIG. 12, a module unit and a battery are arranged separated from each other. That is, an electronic apparatus according to the present embodiment 1 adopts a case including a first capacity part and a second capacity part both arranged separated from each other to thereby accommodate the module unit in an internal space of the first capacity part and accommodate the battery in an internal space of the second capacity part.

A bovine estrus detection device includes a generally rectangular base having sides and ends, the base having a predetermined length and a predetermined width, and the width being less than the length, the base having a first side and. a second side. The first side of the base has a central region having a first color and end regions having a second color. The second color is different from the first color. An adhesive is disposed on the second side of the base for coupling the base to a female cow or heifer. A removable coating is disposed over the first side of the base. The removable coating is exposed for contact by male or female cows mounting the female cow or heifer to which the device is attached. The coating is adapted to being removed by mounting male or female cows, whereby the first and second colors become visible. Exposure of the first color in the central region is an. accurate predictor of activation and estrus.

System for determining a respective walked distance of animals in a barn during a predetermined time period. The system includes a Real-Time Location System, a database storing historical trajectories of the animals and a processing controller. The processing controller is configured to determine the walked distance of the animal by establishing a walked trajectory based on obtained data entities, and store the trajectory in the database associated with the animal; or detecting a gap of missing or incomplete data entities among the obtained data entities; and establish the trajectory by inserting replacement distance data in the gap, based on historical trajectories extracted from the database and store the established trajectory in the database.

An estrous sensor, which is implanted into a body of a domestic animal and detects estrus of the domestic animal, includes a first channel interface circuit, an output circuit, a temperature measurement circuit, and determination circuit determines whether the domestic animal is estrous based on the electrical conductivity of the body fluid of the domestic animal and the temperature within the body of the domestic animal.

A housing structure with an opening and an adhesive is combined to the bottom of the housing structure for adhering the housing structure to the skin of an animal. A pocket accessible through the opening in the housing structure for inserting and holding a warning device in direct contact with the skin of the animal through the opening. The housing structure of the adhesive patch can comprise a base layer comprising a bottom side on which the adhesive layer is attached.

Exemplary embodiments are directed to sensor apparatuses for attachment to an animal that include a housing and a sensor assembly. The housing can be attachable to the animal and includes an internal cavity formed therein. The sensor assembly can be disposed within the internal cavity of the housing. The sensor assembly includes a force sensor and an accelerometer arranged to detect force data and accelerometer data representative of a physiological state of the animal. Exemplary embodiments are also directed to method and sensor systems for detecting a physiological state of an animal.
