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.

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 accurately 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 other sports and physical activities.

Swimming goggles are developed to allow a swimmer to see the end of the pool without moving their head while swimming in backstroke. Using a light reflector, a swimmer can see through a backstroke viewing window, allowing them to see along the direction that they are moving when swimming backstroke. Using a motion sensor and electric control circuits, a swimming goggle can provide optimum views for the swimmer wearing the swimming goggle. Using a sound speaker, a swimming goggle can play music and provide voice reports to the swimmer. The electronic controller for a swimming goggle can either be embedded as part of a swimming goggle, or can be detachable to support more than one swimming goggle.

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. To improve water resistance, magnetic switches are utilized as selection switches. The wearable electronic device can also support similar functions for other sports and physical activities.

Using a sound speaker, a swimming goggle can play music and provide voice reports to the swimmer. Flow meters and inclinometers can be used provide measurements with better accuracy. The electronic controller for a swimming goggle can either be embedded as part of a swimming goggle, or can be detachable to support more than one swimming goggle. Besides swimming goggles, the electronic devices also can be attached onto athletic headgears such as eye goggles, sweat bands, hats, or helmets.

A mobile phone is constructed with methods that use either one or a plurality of microphones to provide warnings for the user of dangerous incoming vehicles. These warnings are displayed on the screen of the mobile phone, and such warnings indicate the direction of a vehicle, the level of danger that each vehicle poses to the individual, and the type of vehicle that is approaching. These methods are all determined by the Short Time Interval Fourier Transform (STIFT) method, wherein said STIFT method consumes minimal computing power relative to mobile phones.

Distress signal transmitters of the present invention are designed to maximize the chance for a victim to survive an accident, and minimize the time for a rescue party to find a victim. The preferred embodiments of the distress signal transmitters of the present invention are to be self-powered, self-activated, and to remain fully functional when dropped into salt water. This will allow the Radio Frequency (RF) distress signals to be sent over a long distance, even if the user is unconscious or severely injured. Furthermore, a set of coordinates determined by a Global Positioning System will be transmitted with the S.O.S message in order for search parties to quickly and efficiently pinpoint the location of the victim(s).

Swimming goggles allow a swimmer to see the end of the pool without moving their head while swimming in backstroke. Using a light reflector, a swimmer can view through a backstroke viewing window to view along the backstroke moving direction. Swimmers wearing the goggles can therefore reduce the chance for injury while helping backstroke swimming efficiency.
