An apparatus and method for measuring a swimmer's speed and conveying the speed to the swimmer in real time includes a plurality of ultrasonic beacons each having a transducer configured to emit ultrasonic signals in a pool or other body of water within which the swimmer is swimming. A wearable, waterproof, ultrasonic receiver worn by the swimmer, receives the ultrasonic signals and generates corresponding signal data. The receiver's microcontroller captures and uses the signal data to calculate the swimmer's position and speed in real time, and conveys this information to a wearable, waterproof, user interface device worn by the swimmer, the user interface device including a near-eye display disposed on the swimmer's googles.

The present invention is new art with a new function and is comprised of goggles or a mask that has an ornamental design on the lens component of the goggles or mask.

The present disclosure provides a heads up display (HUD) system configured for use with a pair of swimming goggles comprising first and second eye cups, a nose bridge connected to inner sides of the eye cups, and strap mounting portions on outer sides of the eye cups. The HUD system comprises an electronics and optics modules. The electronics module comprises a water tight housing and a processor, memory, power supply, sensors and a display within the water tight housing. The processor processes signals from the sensors to determine swimming performance data and controls the display to generate an image containing the swimming performance data. The optics module is mounted on one of the eye cups and is coupled to the electronics module for receiving the image from the display. The optics module extends from the electronics module and has one or more light directing features for redirecting the image toward an eye of a user to generate a redirected image.

Wearable electronic devices that are designed to be worn on the head of a user while the user is swimming can determine swimming strokes and swimming performances of the user using motion sensors. Using a sound speaker, the wearable electronic device can play music and provide audio feedback to the swimmer. By comparing the swimming performance of the swimmer wearing the device with previously recorded swimming data, the wearable electronic device can provide audio comparison results to the swimmer while the swimmer is swimming in water. The wearable electronic device can also support similar functions for jumping actions.

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.

The present application relates to a method of identifying data for producing user-customised goggles, which contacts the face of the user defined by a contacting surface on said face, when the user uses said goggles, the method comprising the steps of receiving an input of 3D-data defining the contour of the face of the user and defining the dimension of the face of the user at least in an area around the eyes of the user, identifying contact areas on the contacting surface, and providing structure-data based on said input of 3D-data and said contact areas, where the structure-data is used for designing at least the part of said goggles, which is adapted to contact the face of the user. The application further relates to a system for producing a pair of user-customised goggles, a pair of user-customised goggles, and a user contacting structure of a pair of user-customised goggles.

A heads-up display for an item of eyewear includes a mounting means configured to mount the heads-up display to the item of eyewear; at least one sensor configured to obtain performance data; a processing unit operatively connected to the at least one sensor, and configured to process said performance data and to generate an image from said performance data; a micro display unit operatively connected to the processing unit, and configured to display the image under the control of the processing unit; and, an optical wave guide in optical communication with the micro display unit, and configured to route the image from the micro display into a field of view of a wearer of the item of eyewear. The heads-up display is configured to overlay the image into the line of sight of the wearer, such that the wearer can view their surrounding environment at the same time as the image, and therefore view their performance data real-time.
