A computing system for measuring and monitoring patient biomarkers for detecting or predicting a post-surgical hysterectomy complication may be provided. A post-surgical hysterectomy complication may be predicted or detected by comparing measured/processed patient biomarker data with a corresponding determined threshold value. The comparison of the measured/processed patient biomarker data and the corresponding threshold may be performed in association with a context. The context may be based on at least one of a hysterectomy surgery recovery timeline, at least one situational attribute, or at least one environmental attribute. A notification message associated with a predicted or detected post-surgical hysterectomy complication may be sent (e.g., sent in real time) to a patient device or a healthcare provider's device. The notification message may be supplemented by a severity level message.

An electrical stimulation apparatus includes: a cell cluster container comprising a cell cluster configured to secrete an active material; an indicator container comprising an indicator; a controller configured to apply a stimulation voltage to the cell cluster container based on a sensing signal received from the indicator container; a first entrance connected to the cell cluster container and configured to allow either one or both of the cell cluster to be retracted and a new cell cluster to be injected; and a second entrance connected to the indicator container and configured to allow either one or both of the indicator to be retracted and a new indicator to be injected.

Devices and methods for providing sensory feedback during an exercise are disclosed. An exertion target is set, for a user performing the exercise, based on a self-calibration that estimates the user's ability using signal amplitudes of surface electromyography (sEMG) data, wherein the exertion target includes a target signal amplitude of muscle contractions to be reached during the exercise. sEMG data are received from a measurement device attached to the user as the user performs the exercise. Upon processing the sEMG data, sensory feedback is generated at a computing device operated by the user, wherein the sensory feedback has an intensity proportional to the user's exertion level as the user performs the exercise, and wherein the sensory feedback changes over a course of the exercise in dependence on a duration that the user maintains a muscle contraction at or above the target signal amplitude, and the change in sensory feedback is configured to encourage the user to prolong the duration.

An elongated device and a system that at the same time allow acquisition of temperature-related data of high spatial and temporal resolution from hollow structures together with other relevant data of physical or chemical variables.

The disclosure makes it possible to evaluate thermal variations when the inner surface returns to pre-change thermal conditions. High-resolution data can be obtained with the disclosure. The disclosure further includes a system with rotators, injection pumps, a control unit and display operably coupled to one or more of the data acquisition and processing system.
