Abstract: The present invention provides an eating monitoring method for judging whether chewing is performed or not by a chewing judgment algorithm on the basis of a temporal variation in a measured value of a sensor unit configured to detect a movement of a jaw while a person takes a meal, the person wearing a detection device comprising the sensor unit. The method includes the steps of: adjusting the chewing judgment algorithm on the basis of a variation in a measured value of the sensor unit, the variation corresponding to a chewing action or a mouth opening/closing action of the person wearing the detection device; and judging whether chewing is performed or not by the chewing judgment algorithm which has been adjusted, and measuring the number of chews on the basis of a temporal variation in a measured value of the sensor unit during the meal.

Abstract: Aspects of the disclosure relate to methods of conducting an intraoperative procedure including providing an electrode assembly having a pledget substrate having a surface that is hydrophilic, at least one electrode supported by and positioned within the pledget substrate, and a lead wire assembly interconnected to the at least one electrode. Methods can further include creating an incision to access bioelectric tissue of a patient and applying the pledget substrate to the tissue, such as a nerve, for example.

Abstract: Embodiments of the present invention may provide a limb motion sensor system (100) used to objectively assist detection of equine lameness and even monitor change in gait quality over time. Biosensors (102) may be attached to the pair of front and/or hind limbs. Each conformally shaped biosensor device may be placed lateral to the metacarpal/metatarsal bone (e.g., attached to the lower limb). Inertial data may be collected by the set of sensor devices and may be wirelessly transferred to a portable, perhaps wearable, mobile controller and analytics unit (104) (e.g., smart phone, tablet, or the like). A signal processor application (108) may automatically segment each stride into phases and perform analyses to quantify limb motion metrics and uniformity over time for a single limb (unilateral consistency) or between the contralateral limbs (bilateral symmetry). Three-dimensional motion metrics may be processed, displayed, stored on, and even transmitted from the mobile information system.
