Methods, systems, and devices for menstrual cycle onset prediction are described. The method may include receiving physiological data associated with a user from a wearable device, the physiological data including at least temperature data. The method may include fitting the received temperature data to a trigonometric or polynomial function including a plurality of features and calculating a duration between the plurality of features and a corresponding plurality of menstrual cycle onset days. The method may include estimating a future menstrual cycle onset day that the user experiences a first day of a menstrual cycle based on applying the duration to a most recent feature of the trigonometric or polynomial function. In some cases, the method may include causing a graphical user interface of a user device to display an indication of the estimated future menstrual cycle onset day.

Physiological parameters such as respiratory rate and/or heart rate variability can be measured over time for a user and correlated to physiological and/or hormonal cycles such as the menstrual cycle. By determining the phase of such a cycle in this manner, an automatic coach for the user can recommend phase-specific adjustments to activities such as sleep and exercise.

A hearable comprises a wearable structure including a speaker, a sensor, and a temperature compensating circuit which measures temperature in an environment of the sensor. A portion of the wearable structure, which includes the sensor and temperature compensating circuit, is disposed within a user’s ear when in use. A sensor processing unit which is communicatively coupled with the temperature compensating circuit: acquires temperature data from the temperature compensating circuit while the portion of the wearable structure is disposed within the ear of the user; builds a baseline model of normal temperature for the user; and compares a temperature measurement acquired from the temperature compensating circuit to the baseline model. In response to the comparison showing a deviation beyond a preset threshold from the baseline model, the sensor processing unit generates a health indicator for the user which is used to monitor an aspect of health of the user.

An apparatus and methods for detection of estrus and optimal time for embryo transfer or artificial insemination in animals. An arched polycarbonate housing is attached to an animal. A circuit board is disposed within the housing. A rechargeable battery mounted on the circuit board provides power to the apparatus. A switch mounted on the circuit board is actuated when a breeding behavior occurs. A controller mounted on the circuit board detects actuations of the switch to generate data indicative of breeding behavior. A transmitter transmits data indicative of breeding behavior to a remote receiver.

A sensing assembly having: a sensing device having first and second opposing major surfaces, a first sensor located in the device and positioned for preferentially sensing a parameter at the first major surface and a second sensor located in the device and positioned for preferentially sensing the parameter at the second major surface; and a wearable carrier for embracing a part of the human or animal body, the carrier having a hole extending fully therethrough; the sensing device and the carrier being cooperatively configured so that the sensing device can be releasably lodged in the hole in the carrier so that when the carrier is embracing the body part the sensing device can be held against the body part by the carrier with one major surface of the sensing device facing the body part and with no part of the carrier between the sensing device and the body.

Embodiments of a vaginal temperature sensing apparatus, a visually sense-able battery power-on indicator (16), manufacturing with cure temperatures that protect a battery, substantially error-free, user-initiated device activation componentry (30) to start battery power, and a timer to automatically terminate flow of battery power. Data can, by an automatic data transform recalculator (138) with body temperature dips in transformed and recalculated diurnal high body temperatures, predict an ovulation event and provide an indication through a zenith based ovulation indicator (106). Systems can include neural network based artificial intelligence to automatically self-improve by using historical or even other, multi user data and user input and improve its indication result.

Embodiments are directed to systems and techniques for tracking menstrual cycles, which can include receiving temperature measurements from an array of temperature sensors positioned on a bed. A use period for the array can be determined when temperature measurements from at least one temperature sensor of the one or more temperature sensors exceed a first temperature threshold. In some embodiments, for each use period in a set of two or more use periods, a temperature of the user using the set of temperatures from the respective use period can be determined. After determining the temperature of the user for each use period in the set of two or more use periods, at least one change in the temperature of the user between different use periods can be identified. An ovulation day of the user based on the at least one change in the temperature of the user can be estimated.

An object is to prevent of display of display of candidates unlikely to be selected. An information processing device a target date associated with an input value to be input. The information processing device displays candidates for an input value on a screen. At this time, the information processing device displays a first number of candidates when the target date is included in a first period during which the information changes in a first range. The information processing device displays a second number of candidates that is smaller than the first number when the target date is included in a second period during which the information changes in a second range that is narrower than the first range. The first period and the second period is included in a cycle in which the information changes.

Heath care system has a server providing service for caring for the health state of each user, and a terminal of the user. The server registers and manages health information including examination results, body temperature and menstruation data of each user based on operation from the user terminal, determines the health state of each user, including a tendency of variation of values of an examination item, based on comparison of time series values of the examination item of the examination result data and based on comparison result between the values of the examination item of the examination result data and a numerical range of reference information corresponding to the examination item, and outputs, to the user terminal, information including a graph of the examination result data, a graph of the body temperature and menstruation data, and a message appropriate for the health state of each user.

A measuring device for measuring a body temperature of a living being includes a measuring unit for measuring the body temperature. The measuring device includes a first adhesive layer for fastening the measuring device on the body of the living being. The first adhesive layer is arranged at a side of the measuring device intended to face the body when the measuring device is in use. The measuring device includes a skin-compatible protective layer, which is arranged between the first adhesive layer and the measuring unit.
