Title: Athletic eyeglasses system and method

Description:
BACKGROUND OF THE INVENTION 
     This invention provides an athletic eyeglasses system and method for monitoring and displaying to an athlete relevant information such as elapsed time and heart rate, in real time. 
     In many athletic activities the element of time is very important, and it is desirable and useful to see the elapsed time during performance of the activity. Looking at a timekeeping device such as a wristwatch or stopwatch, however, requires at least momentarily diverting attention and focus away from the athletes view of what is ahead. In some activities even momentary diversion of attention can be dangerous or otherwise disadvantageous. And intermittent glances at a watch only provide intermittent information about time. In some activities, the disposition of the arms and hands is limited by considerations of balance or of propulsion, making any device held in the hand or mounted on the wrist or arm even less useful. 
     Also important in many athletic activities, such as distance or endurance running, riding, or rowing, it is beneficial to be able to monitor, in real time, the measure of one or more physiological conditions, such as heart rate or pulse rate, in order to make better-informed expenditures of energy. Again, the necessity of at least momentarily diverting attention and focus to look at a device can be dangerous or disadvantageous, and only provides intermittent information. 
     What is needed is a system and method for determining and displaying the relevant information about time and physiological condition, in real time, in a way that can be seen and comprehended by the athlete without any diversion of attention or focus and without any extraneous movement of the hands or arms.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to  FIG. 1 , the athletic eyeglasses system  10  and method monitors and reports data regarding time and physiological condition to an athlete such as a runner, in real time, in a way which does not require looking away from the normal view forward ahead of the athlete. For a running athlete, the relevant time data is likely to be the time elapsed since a starting signal such as a starter&#39;s gun, and the relevant physiological data is likely to be heart rate or pulse rate. The availability of this data in real time and without diverting attention from the conditions ahead can be beneficial to an athlete, especially during an event requiring controlled use of physical resources, such as distance or endurance running, riding, or rowing. 
     An eyeglasses frame  1  and two frame arms  2  are provided, as shown, and form a glasses frame for the athlete to wear in the usual way. Two display glass units  3  are mounted in the eyeglasses frame  1 . Each display glass unit  3  provides one or more data displays  4 , as shown, which display data within the athlete&#39;s field of vision such that the athlete does not need to look away from what would normally be looked at during his or her athletic activity. The data displays  4  can be implemented using technology known in the art, such as liquid crystal display technology. 
     Power for the data displays  4  and other functioning of the athletic eyeglasses  10  is provided by a battery  5  mounted within one of the frame arms  2 . One or more input buttons  6  are provided on one or both frame arms  2 . The input buttons  6  can be used, for example, for activation and deactivation of the system, for adjusting the intensity or size of the data displays  4 , for switching between modes such as a day mode and night mode, or for adjusting exactly what data is displayed and exactly how it is displayed. 
     A controller unit  7  mounted within one of the frame arms  2  is provided, which controls the display of data by the data displays  4 , including the obtaining of data from sensors  13 ,  14 , as disclosed below, and the keeping of time to be displayed. 
     A timer starter  8  is provided to trigger the measurement and display of elapsed time through the controller unit  7 . The timer starter  8  can be implemented as a button, which might be appropriate in some circumstances such as self-directed training. Reaching to press a button at the start of an athletic event is likely not an advantageous nor accurate way to start the timer in most circumstances. In an embodiment of the athletic eyeglasses  10 , the timer starter  8  can be implemented as a sound-activated trigger which reacts to a loud sharp noise such as a starter&#39;s gun, or a horn, or a buzzer. In another embodiment of the athletic eyeglasses  10 , the timer starter  8  can be implemented as an accelerometer which reacts to the initial acceleration at the start of an event. Yet another embodiment can provide multiple implementations of the timer starter  8  function, with a provision for choosing among the implementations. 
     A port  11  having a port cover  12  is provided on one of the frame arms  2 . The port  11  provides for charging the battery  7  by accepting the power to do so. The controller unit  7  can control the charging process to prevent overcharging. In an embodiment of the athletic eyeglasses  10 , the port  11  can also be used for transfer of data into and out of the controller unit  7 . The port  11  can be a USB port operating under the applicable USB standards. 
     A sensor  13  mounted to a frame arm  2  is provided for the purpose of sensing one or more physiological measurements, such as heart rate or pulse rate. A sensor measuring pressure, sound, temperature, electrical properties, or other indicators might be used. More than one sensor can be provided and might be necessary when measuring some types of physiological conditions. The sensor  13  or sensors can be placed along one or both frame arms  2  in order to best sense the physiological condition. A measurement of heart rate or pulse rate is likely to be an important measurement for display for most uses of the athletic eyeglasses  10 . 
     Referring to  FIG. 2 , in an embodiment of the athletic eyeglasses  10  the sensor, or one of the sensors, can be a tethered sensor  14 , as shown. 
     Peripheral oxygen saturation (SpO2) is an estimate of the percentage of oxygenated hemoglobin in the blood. Peripheral oxygen saturation is measured by pulse oximetry, where a device shines light through a peripheral part of the body, usually a finger or an earlobe, and measures the absorption of light. Real-time availability of SpO2 data can be beneficial to an athlete, especially in distance or endurance events. Determining peripheral oxygen saturation (SpO2) might best be done using a tethered sensor  14  which clips to the earlobe. Heart rate or pulse rate can also be determined when using pulse oximetry, and both the peripheral oxygen saturation and the pulse rate might be displayed on the data display  4  of the athletic eyeglasses  10 . 
     Referring to  FIG. 3  and  FIG. 4 , the port  11  located on a frame arm  2 , which is used for charging the battery  5  and optionally used for input and output of data to and from the controller unit  7 , is covered by a port cover  12 , for protection against intrusion of water, dust, or sweat during use or during storage. The port cover  12  can be moved out of the way for charging or data transfer. 
     Referring to  FIG. 5 , in another embodiment of the athletic eyeglasses  10 , the eyeglasses frame  1  has a different configuration but the same function. The data displays  4  can show symbols such as numerals, alphabetic characters, and graphic symbols, such as the heart symbol  15  shown, which can be made to flash or pulse in a rhythm tracking the heart rate, or can be made to appear, flash, or change color when a defined value of data is detected. 
     Many other changes and modifications can be made in the system and method of the present invention without departing from the spirit thereof. I therefore pray that my rights to the present invention be limited only by the scope of the appended claims.
