Heart pulse rate monitor
First Claim
1. A heartbeat monitoring device comprising:
- at least one sensor package mountable over a pulse location of a user, wherein each sensor package includes;
a first sensor configured to sense at least one signal at the pulse location and to provide a first output signal comprising a heartbeat signal and a first set of noise artefacts;
(ii) a layer of isolating material located above the first sensor; and
(iii) a second sensor located above the first sensor and configured to sense at least one signal at the pulse location and to provide a second output signal comprising a second set of noise artefacts; and
processing circuitry connected to each of the at least one sensor package, the processing circuitry being configured to extract the heartbeat signal from the first output signal based on at least the first output signal and the second output signal.

Abstract
Disclosed herein are methods and devices for monitoring a heartbeat. In one embodiment, the device may comprise a sensor package mountable over a pulse location of a user. The sensor package may include a first sensor element configured to sense at least one signal at the pulse location and to provide a first output signal comprising a heart pulse signal and a first set of noise artifacts, a second sensor element configured to sense at least one signal at the pulse location and to provide a second output signal indicative of a second set of noise artifacts, and a mechanically isolating material located between the first sensor element and the second sensor element. The device may further comprise processing circuitry connected to the sensor package and configured to extract the heart pulse signal from the first output signal based on the first output signal and the second output signal.

18. A heartbeat monitoring device, comprising:
-
a first packaging layer adjacent to skin of a user; a first sensor above the first packaging layer, the first sensor being configured to sense a primary set of signals comprising at least a heartbeat signal and a first set of noise artefacts; a second sensor above the first sensor, the second sensor being configured to sense a reference set of signals comprising at least a second set of noise artefacts, wherein the first sensor and the second sensor are arranged in a vertical stack over a horizontal plane defined by the skin; a second packaging layer between first sensor and the second sensor; a third packaging layer above the second sensor; and a strap for attaching the device to the user, the strap being adjacent to the third packaging layer. - View Dependent Claims (19, 20, 21, 22)

23. A method for detecting a heartbeat signal, comprising:
-
using a primary sensor to sense a first set of signals comprising at least a heartbeat signal and a first set of noise artefacts, wherein the primary sensor is positioned over a pulse location; using a reference sensor to sense a second set of signals comprising at least a second set of noise artefacts, wherein the reference sensor is positioned substantially over the primary sensor; based on the second set of noise artefacts, removing the first set of noise artefacts from the first set of signals so as to isolate the heartbeat signal; and transmitting the heartbeat signal to a remote device.
