Abstract: A photoplethysmographic (PPG) device is disclosed. The PPG device can include one or more light emitters and one or more light sensors to generate the multiple light paths for measuring a PPG signal and perfusion indices of a user. The multiple light paths between each pair of light emitters and light detectors can include different separation distances to generate both an accurate PPG signal and a perfusion index value to accommodate a variety of users and usage conditions. In some examples, the multiple light paths can include the same separation distances for noise cancellation due to artifacts resulting from, for example, tilt and/or pull of the device, a user's hair, a user's skin pigmentation, and/or motion. The PPG device can further include one or more lenses and/or reflectors to increase the signal strength and/or and to obscure the optical components and associated wiring from being visible to a user's eye.

Abstract: Elektrische Felder, die zur Korrosion von Kontakten führen können, können durch Ausführungsformen der vorliegenden Erfindung kompensiert werden. Beispielsweise können Spannungswellenformen an den Kontakten so gestaltet werden, dass sie einen Mittelwert von null Volt aufweisen und somit insgesamt kein elektrisches Feld erzeugen. Galvanische Spannungen, die durch die von einem Kontakt und einem Gehäuse verwendeten unterschiedlichen Metalle erzeugt werden, können ein elektrisches Feld erzeugen, und durch das galvanische elektrische Feld verursachte Ströme können durch kapazitive Kopplung der Kontakte an ihre entsprechenden Schaltungen blockiert werden.

Abstract: A PPG signal may be obtained from a pulse oximeter, which employs a light emitter and a light sensor to measure the perfusion of blood to the skin of a user. However, the signal may be compromised by noise due to motion artifacts. To address the presence of motion artifacts, examples of the present disclosure can receive light information from each of two light guides, one in contact with the tissue of the user and one not in contact with the tissue of the user. First light information can be obtained from the first light guide, and second light information can be obtained from the second light guide. A heart rate signal can then be computed from the first and second light information, for example, by using blind source separation and/or cross-correlation.

Abstract translation: PPG信号可以从采用光发射器和光传感器的脉搏血氧计获得，以测量血液对使用者皮肤的灌注。 然而，由于运动伪影，该信号可能被噪声所损害。 为了解决运动伪影的存在，本公开的示例可以从两个光导中的每一个接收光信息，一个与用户的组织接触，而不与用户的组织接触。 可以从第一光导获得第一光信息，并且可以从第二光导获得第二光信息。 然后可以例如通过使用盲源分离和/或互相关从第一和第二光信息计算心率信号。
