The present invention relates to an exercise analysis system using a sensor worn on a user's head, and more specifically, to an exercise analysis system for measuring acceleration signals according to movement of a user's head using an accelerometer worn on the head, and separately analyzing exercise postures corresponding to the movement of the head by identifying user's left and right, front and rear, or up and down direction from the measured acceleration signals.

The present invention provides materials and methods for forming an interface between an appliance and living tissue using a foamed elastomeric material which contacts the tissue or similar surfaces. The elastomeric material is in the form of a durable and washable material that, when applied to or implanted in living tissue or similar surfaces, displaces and flows in to non-conforming areas creating an air and/or water tight seal that substantially returns to an original shape when removed from the contact surface. The appliance may also include structural elements designed to optimize comfort, compliance and seal achieved through minimizing the pressure variation along the contact surface of the therapy device.

The present invention provides a lens assembly structure of swimming goggles. The lens assembly structure comprises two lenses, two retaining walls, two skirt portions, and two frame portions. Each of the lenses includes an eye side and a water side opposing to the eye side. The two retaining walls are provided on the eye sides of the lenses, respectively, and each of the retaining walls defines a visible area and a connection area. Each of the retaining walls has a configuration, and the corresponding skirt portion is disposed along the configuration. The connection area of the lens is affixed in the corresponding frame portion. The configuration of each of the retaining walls is a curve having a contour which is less complicated than a peripheral configuration of the lens.

Embodiments of the invention concerns a method of designing a sports article, including: (a) scanning at least one body part of at least a first person; (b) creating a first digital model of the body part of the first person; (c) creating a digital model of the sports article; (d) digitally arranging the digital model of the sports article on the first digital model of the body part, while allowing the digital model of the sports article to stretch digitally and (e) digitally modifying at least one property of the digital model of the sports article based on the first digital model of the body part and the digital model of the sports article.

The invention relates to spectacles, systems and methods for visibility enhancement, including by glare suppression. The spectacles, systems and methods for visibility enhancement includes spectacles and a spectacle lens having a liquid crystal cell (LC), the transmission (TR) of which may be varied by a suitable control and the liquid crystal cell (LC) designed so that the transmission (TR) of the liquid crystal cell (LC) may be switched between high and low transmission states. The liquid crystal cell (LC) includes a control for regulating the times of the state of high transmission (T.sub.on) of the liquid crystal cell (LC) such that the temporal position of the times of the high transmission state (T.sub.on) within a period of times of the high transmission state (T.sub.on) and times of the low transmission state (T.sub.off) may be altered continuously or discontinuously; and/or the duration of a period of times of the high transmission state (T.sub.on) and times of the low transmission state (T.sub.off) may be altered continuously or discontinuously. Such changes may be determined by a secret coding key.

A wearable computing device that is secured or attached to a resilient strap, the resilient strap sized to fit around at least a part of a circumference of a human head. The device has a waterproof storage volume housing a plurality of sensors. The wearable computing device may calculate a plurality of swimming metrics based at least partly on data received from the at least one sensor. The wearable computing device may include a wireless communication subsystem secured to the resilient strap within the waterproof storage volume and may transmit at least one of the calculated plurality of swimming metrics to at least one computing device via the wireless communication subsystem. The wearable computing device may include at least one user output component and may present an indication of at least one of the calculated plurality of swimming metrics at the at least one user output component for communication to the user. The indication may be audio played in an ear piece connected to the strap, or may be visually displayed on a display in an eye goggle portion of the strap.

The present disclosure provides a pair of swimming goggles comprising a glass insert in each goggle lens. Each goggle lens comprises a body constructed form a substrate material and a glass insert received within a lip extending upwardly from around the perimeter of the body. The glass insert may be installed on top of a coating on a substrate material of the goggle lens. The glass insert may comprise a glass plate having an adhesive sheet on an underside thereof.
