Embodiment Construction

[0044] As mentioned in the background, optical HRM is adversely affected by changes in the distance between wearable sensors (including illumination sources and light detectors) and the skin, as well as in the orientation and shape of the skin surface. Many solutions have been proposed before to deal with this problem.

[0045] One option is to securely strap the sensor to the wearer's body to maintain a constant distance between the sensor and the skin. However, this can cause discomfort to the wearer and prevent long-lasting use of the device. Another solution involves monitoring the sensor-skin distance and / or the motion of the wearer's body, and using this information to compensate for any measurement errors. Disadvantages of this approach include the need for additional computing power, dedicated logic units, and digital-to-analog converters, which increase the sensor's complexity, cost, size, and power consumption. Additionally, the distance and motion information obta...

Abstract

A wearable apparatus including a waveguide configured to act as a conduit for light emitted from an illumination source to a photodetector via an interaction portion of the waveguide, the interaction portion configured to channel the light out of the waveguide to enable interaction of the light with a wearer's body and back into the waveguide to enable detection of the interacted light by the photodetector.

Description

technical field [0001] The present disclosure relates to the field of health and fitness monitors, related methods and apparatus, and in particular, to waveguides comprising photodiodes for directing light from an illumination source through the wearer's body. Certain disclosed exemplary aspects / embodiments relate to portable electronic devices, in particular, so-called hand-portable electronic devices, which are carried in the hand (although they may be placed in a cradle during use) superior). Such hand-portable electronic devices include so-called Personal Digital Assistants (PDAs) and desktop PCs. [0002] Portable electronic devices / apparatus according to one or more disclosed exemplary aspects / embodiments may provide one or more audio / text / video communication functions (such as telecommunications, video communication, and / or text transmission), short message service ( SMS) / Multimedia Messaging Service (MMS) / email functionality, interactive / non-interactive viewing funct...
