- A61M2230/04—Heartbeat characteristics, e.g. ECG, blood pressure modulation
- A61M2230/06—Heartbeat rate only
Definitions
- the one or more characteristics are preferably obtained in the time domain of the signal from the user’s heart. This reduces computational cost and processing time of the signal.
- the one or more characteristics comprise features of an electrocardiogram obtained in the frequency domain of the signal from the user’s heart.
- Figure 4 is a graph showing an electrocardiogram signal
- Figure 5 shows an arrangement of electrodes on a vaping device
- a heart rate sensor 204 is integrated into the activation switch 104 such that when the user touches or presses the switch 104 to turn on the vaping device 100 the sensor 204 measures the heart rate of the user by skin contact, as will be described in detail later.
- two electrodes A and B are brought into contact with the skin of a user during use of the vaping device 100.
- the two electrodes A, B measure an ECG of the user and compare the ECG measurements to ECG measurements stored within a user profile. If the ECG measurements match the user profile, the user is an authorised user and the vaping device 100 is unlocked. If the ECG measurements do not match the user profile, the user is not an authorised user and the vaping device 100 is locked.
- the data measured by the heart rate sensor 204 represents a voltage fluctuation over a period time in seconds.
- the measured data is first processed in order to identify the specific number of heartbeats that were detected and measured, using techniques well known in the art for examples by counting R-peaks within data signal.
- the data is normalised for both time and amplitude.
- each individual heartbeat within the measured data can be identified and then averaged in order to provide an average heartbeat of the user in question.
- the identification and averaging steps are carried out using standard techniques that are well known in the field of electrocardiography. Once an individual heartbeat has been identified, the three main components of the ECG are then extracted from the data.
- the construction of the heart rate sensor and electrodes could take a number of different configurations. Some of these configurations will be described in further detail below.
- the heart rate sensor position and arrangements of electrodes on the vaping device 100 varies depending on the particular form of the overall vaping device 100 to which the heart rate sensor 204 is being applied. The following description will provide details about the arrangements of the heart rate sensor electrodes A, B on different forms of vaping device 100.
- both electrodes A and B are substantially circumferential, extending around substantially the entire circumference of the vaping device 100.
- at least one of the electrodes extends fully around the entire circumference of the vaping device 100 such that the at least one electrode takes the form of a ring on an outer surface of the vaping device 100.
- the distance between the two electrodes A and B is as large as possible, to ensure better measurements being taken from each electrode.
- a greater distance between electrodes A and B means that more skin can be measured, resulting in more consistent results than would be achieved over a shorter measuring distance.
- the voltage drop over a larger distance is higher than over shorter distances (which have a smaller voltage drop) which gives a better measuring accuracy.
- the only requirement is that the two electrodes A, B are positioned such that a typical grip of the vaping device 100 by a user results in the user making skin contact with both electrodes.
- optional reference electrode R can be located between the two electrodes A and B.
- the two electrodes A, B extend around at least a portion of perimeter of the vaping device.
- perimeter is used to mean the side walls of the box-like structure rather than top and bottom/base faces.
- at least one of the electrodes may partially extend over a part of the base of the vaping device, as well over a part of a side wall of the vaping device 100.
- the electrode A can be thought of as being at least partially wrapped around an edge of the vaping device 100, for example a lower body edge when the vaping device 100 is held in its operative configuration.
- the activation element may comprise a first electrode, for example electrode A, as shown in Figure 1.
- the electrodes A and B may comprise a multi-electrode surface.
- each electrode of the multi-electrode surface must be electrically connected within the vaping device.
- electrode A may comprise a plurality of sub electrodes (for example electrodes A1 , A2, and A3) and these sub-electrodes are electrically connected together, and operate together, to form electrode A.
