Definitions

  • the present invention relates to an ear based fitness and lifestyle device designed to suit people with varied activity levels and lifestyles by trying to provide them information on their quality of life and further to engage and inspire them to be more wellness conscious, by consciously and gradually altering their lifestyle by aiding them where possible.
  • Heart rate is typically calculated using an ECG, pressure sensors near arteries or veins or by the use of pulse oximeters.
  • US5513642 entitled “Reflectance sensor system” disclosed a form of reflected pulse oximeter, where the sensors were placed on the same plane as the light-emitting source, improved the earlier system. This would allow for a much smaller oxygen saturation and heart rate calculating device, and would avoid the need for clips.
  • This patent formed the basis of many others that followed; including US20100113948 entitled “Heart Rate Measurement” which describes a device that calculated one's heart rate from around the ear.
  • This patent also improves upon the earlier patents by detecting dark signal which may be derived during an off phase of a duty cycle of an emitter and a photoplethysmogram system arranged to select between a plurality of detectors, which would mitigate motion artefacts, thereby making the heart rate monitor more mobile.
  • US20120078119 titled “Method and apparatus for robust heart rate sensing” discloses fitness devices, which integrates both heart rate and physical activity sensing from the ear wherein the innovators place an optical heart rate sensing module and an accelerometer within an ear cuff.
  • An ear cuff is designed by the innovators to ensure a stable hold of the device, even during much physical movement due to exercise.
  • these add-ons to the device not only increase the discomfort to the user, who has to tightly secure the device, but also increase battery consumption by adding additional sensors onto the device.
  • the device also varies the gain of the amplifiers based on the pressure applied when the cuff is clipped to the ear.

  • the innovation must also work seamlessly, whereby it must function despite the surrounding of the user.
  • This device has to be intelligent enough to use these vital sign data, to aid and inform the user, so that he may enhance his fitness and wellbeing. Therefore, there is a need not only for a fitness device, but one that alters the user's lifestyle to a more fitness oriented one.
  • the device is designed to provide greater accuracy in its heart rate and accelerometer calculation.
  • the device primarily consists of an accelerometer and a heart rate monitor within a miniature device placed over the ear thereby ensuring the discrete usage of the device. Such placement over the ear is done by the use of magnets, which would ensure minimal user interaction, and no mechanically moving elements in the design.
  • the usefulness of not using mechanical parts allows the entire device to be completely enclosed within a plastic enclosure, as the main means of charging would be through wireless induction charging, making the device completely waterproof.
  • the device is further supported by gesture control, wireless communication and has an inbuilt memory.

  • the device includes a microcontroller, a vibrator and a wireless networking module, which allows it to communicate with other devices, such as smart phones, computers, etc.
  • the invention is designed to extract heart rate using reflected photoplethysmography from behind the ear. The means of measuring this is done by the use of infrared (IR) LEDs and photodiodes. The portion of the IR light behind the LEDs, which is transferred through the skin of ear into the capillaries within it, is absorbed or reflected by oxygenated or deoxygenated blood respectively.
  • IR infrared
  • This absorption and reflection of light can be measured by the use of an IR photodiode, which is placed on the same side as IR LEDs, and hence allows the device to determine the frequency at which the heart is pumping blood to the capillaries, thereby determining the heart rate.

By applying a low-pass digital filter below 0.7 Hz, it's possible to extrapolate respiration rate.

  • Figure 5 illustrates the communication between the device and the charging dock, so that the user may understand whether the device is charged or charging.
  • Figure 1 illustrates the internal components of the ear based device which is covered by plastic shell (101,103) and creatively uses space by placing the battery (104) at a perpendicular angle to the PCB board (105).

  • the front plastic cover (101) has a cut out/marking (102), which will either be made of a transparent material or be affixed with a transparent material, so as to allow the LED and Photodiode to acquire the information from the ear.
  • Figure 2 highlights the means by which the device is affixed onto the ear (109).
  • the body contains a magnet (107), the same body is also fixed to a flexible material (111), which contains another magnet (110). The magnetic force between the magnets will ensure the device is placed on the ear.
  • the use of magnets is a novel step in the design of the innovation, as it ensures a stable and constant contact between the ear and the device; additionally as the head and hence the ear, experiences minimal reverberations during walking or running, (as compared to any other body part) due to the torso and the abdomen acting as shock absorbers, the device experiences very minimal motion artifacts, and hence ensure that the signal that is received has much lesser noise than if it's placed elsewhere.
  • the magnets placed on the ear also ensure that the device doesn't succumb to motion due to its own weight, and ensure minimal movement of the device.
  • the heart rate sensor is reflective, i.e. the sensors are placed on the same side of the ear, placing the magnet directly opposing them on the other side of the ear, also reduces the noise that may interfere due to ambient infra-red light.
  • magnets have a long life, and do not alter the functionality of the device, as well as ensure that there are no mechanical parts on the device. This combination of placing the innovation on the ear using magnets will ensure the lowest noise possible during most form of high physical activity.

  • Respiration rate or the breathing rate may be co-related to multiple health and wellness information, including Stress onset, sleep onset, Apnea, and Asthma. Respiration rate information is also useful in the determination of certain exercises, such as Yoga, which relies heavily on breathing, and ensuring that the user breathes constantly. Hence a device that measures both heart rate and breathing rate, can aid the user by informing them about their performance in such exercises.
  • Physical activity and pedometer calculations can be acquired from the accelerometer placed around the ear. This forms the most optimal position to ascertain the physical activity of the user as the ear moves in tandem with the head, and the head moves in tandem with the whole body. Placement on the ear, removes much of the body movement noise, and focuses on the force acting on the head due to normal human gait, as the body behaves as a shock absorber for the neck, the head and the ear.
  • the accelerometer placed on the ear may also determine head movement (like moving up and down and tilting sideways) which can be characterized in technical terms as pitch and roll angle rotation respectively as shown in Figure 4.
  • the information hence gathered from the pitch information may also provide information of the person's neck posture, thereby also providing information to the user to improve his/her sedentary state.
  • the device is able to determine proper posture (302), which maintains the angle of the head rotation to the normal axis (301 ), as well as poor or improper posture in terms of either concave neck and spine bend (304), which would make the ear's axis shift to the left of the normal axis (303) and poor convex posture (305) makes the ear's axis shift to the right of the normal axis (306),
