Biosensor
Biometric monitoring arrangement discussed herein can be used one, some or all of obtain physiology with lower sensor Data, including but not limited to the physiological data summarized in following table.All combinations and arrangement of biosensor and/or physiological data It is set to fall within the scope of the present invention.Biometric monitoring arrangement may include, but are not limited to identified below for obtaining corresponding physiology One of data, the type of some or all of sensors;In fact, can also or alternatively be obtained using other types of sensor Corresponding physiological data is taken, and these other types of sensors are also set falls within the scope of the present invention.In addition, biometric is supervised View apparatus can export physiological data from respective sensor output data, can be given birth to derived from the sensor including but not limited to it Manage the number or type of data.
In an example embodiment, biometric monitoring arrangement may include optical sensor to detect, sense, sample And/or it generates and can be used to determine the anxiety (or it is horizontal) for indicating such as user, the data of the information of blood pressure and/or heart rate. (see, such as Fig. 2A to 3C and 11A to KKG).In these embodiments, biometric monitoring arrangement may include optical sensor, Its there is one or more light sources (LED, laser, etc.) with send out or output light to user body and photodetector (photoelectricity two Pole pipe, optotransistor, etc.) with sampling, measurement and/or detect this light from the response or reflection of user's body and provide to determination Indicate the anxiety (or it is horizontal) of user, the number of the data of blood pressure and/or heart rate (for example, for example by using photoelectricity volume diagram) According to.
In an example embodiment, the heart rate measurement of user can be by (or being connected to its by one or more sensors Processing circuit) determine criterion and trigger.For example, when the data instruction from motion sensor is static or is transported with few When the dynamic period, biometric monitoring arrangement can trigger, obtain and/or obtain heart rate measurement or data.(see, such as Fig. 9,12A And 12B).
Figure 12 A explanation is with heart rate or PPG sensors, motion sensor, display, vibrating motor and is connected to processor Telecommunication circuit portable biometric metering monitoring arrangement example.
Figure 12 B explanations have heart rate or PPG sensors, motion sensor, display, vibrating motor, position sensor, sea Pull out height sensor, skin electric conductivity/humidity sensor and be connected to processor telecommunication circuit portable biometric metering prison The example of view apparatus.
In one embodiment, when motion sensor indicate User Activity or movement (for example, for triggering, obtain and/or Heart rate measurement or data needed for obtaining (for example, data of the resting heart rate to determine user) improper or simultaneously non-optimal fortune It is dynamic) when, biometric monitoring arrangement and/or sensor to obtain and/or obtain required heart rate measurement or data can be placed in Or it is held in low power state.Because the heart rate measurement carried out during movement may be less reliable and may be by motion artifact Destroy, thus when biometric monitoring arrangement during exercise when, it may be necessary to reduce collect heart rate data sample frequency (thus Reduce power use).
In another embodiment, biometric monitoring arrangement can be used instruction User Activity or the data of movement (for example, coming From one or more motion sensors) it adjusts or changes triggering, obtain and/or the characteristic of heart rate measurement or data needed for obtaining (for example, to improve the robustness to motion artifact).For example, if biometric monitoring arrangement receives instruction user and lives Dynamic or movement data, then biometric monitoring arrangement is adjustable or changes the sampling of the sensor to obtain heart rate data (for example, in the case where user movement amount is more than a certain threshold value, biometric monitoring arrangement can increase for rate and/or resolution model Big sampling rate and/or the sampling resolution pattern for increasing the sensor to obtain heart rate measurement or data).In addition, biometer Measuring monitoring arrangement can be during these of User Activity or the movement period (for example, user movement amount is more than the period of a certain threshold value) The sampling rate and/or resolution model of adjustment or modification motion sensor.By this method, when biometric monitoring arrangement is determining or Detect this User Activity or movement when, biometric monitoring arrangement motion sensor can be placed in higher sampling rate and/or compared with High sampling resolution pattern is for example to realize the more accurate adaptive-filtering of heart rate signal.(see for example, Fig. 9).
Fig. 9 illustrates that changing it based on the mobile degree that biometric monitoring arrangement is undergone detects the mode of user's heart rate Portable biometric metering monitoring arrangement example.The case where detecting movement (for example, via accelerometer is used) wherein Under, user can be considered by biometric monitoring arrangement in " activity ", and high sampling rate heart rate detection can occur to reduce heart rate Motion artifact in measurement.It can save and/or show this data.Determine that user does not move (or phase in biometric monitoring arrangement To sitting) in the case of, low sampling rate heart rate detection (it does not consume so much power) for measure heart rate can be it is appropriate and It can thus be used.
It is worth noting that, for example being obtained by using photoelectricity volume diagram using optical technology in biometric monitoring arrangement In the case of taking heart rate measurement or data, motor message can be used to determine or establish, data acquisition is carried out by heart rate sensor Or measure (for example, synchronous detection is without being non-amplitude modulation method) and/or the ad hoc approach or technology of its analysis.(see, such as Figure 11 E).By this method, indicate the data of user movement or activity can cause biometric monitoring arrangement establish or adjust by The type or technology for the data acquisition or measurement that one or more optics heart rate sensors use.
For example, in one embodiment, when motion detector circuit detects or determines biometric monitoring arrangement (for example, if biometric monitoring arrangement determines user's sitting or sleeping), biometric when the movement of wearer is less than threshold value Monitoring arrangement (or heart rate measurement technology as herein disclosed) is adjustable and/or reduces the sampling rate of optics heart rate sampling. (see for example, Fig. 9).By this method, biometric monitoring arrangement can control its power consumption.For example, biometric monitors Device can reduce power consumption by reducing sensor sampling rate, for example, biometric monitoring arrangement can every 10 minutes it is primary Or every 10 seconds 1 minute Di heart rate is sampled (via heart rate sensor).It is worth noting that, additionally or alternatively, biology Metering monitoring arrangement can control power via data processing circuit analysis and/or data analysis technique is controlled according to motion detection Consumption.As a result, the movement of user may influence heart rate data get parms and/or data analysis or its processing.
Motion artifact in heart rate sensor inhibits
As discussed above, it can be surveyed by PPG sensors with removing motion artifact to improve by using one or more algorithms The original signal of amount.The movement (for determining motion artifact) of usable sensor measurement user, the sensor include But it is not limited to accelerometer, gyroscope, proximity detector, magnetometer, etc..The target of these algorithms is used from as guidance The movable signal of other sensors capture be attributable to mobile component (mobile illusion) remove PPG signals.At one In embodiment, sef-adapting filter can be used to be based on mixing Kalman filter (Kalman filter) and least means square Device or recursive least-squares filter remove the mobile illusion in PPG signals.Peak counting algorithm or power can then be used Spectrum density algorithm for estimating is from cleaning/filtered signal extraction heart rate.Alternatively, Kalman filter or particle filter can be used Remove these movement illusions.
It is Y=Y that the another method that can be used to calculate heart rate frequency, which is by heart rate signal model creation,dc+∑ak*coskθ+ bk* sin k θ, wherein k are the exponent number of harmonic component, and θ is the model parameter for heart rate.This model can then use extension Kalman filter or particle filter and be fitted to signal.This model utilizes following facts:Signal is simultaneously non-sinusoidal, therefore Contain power in both primary harmonic and multiple additional harmonic waves place.
Alternatively, can be Y=Y by signal modelingdc+∑ak*sin(k*wmotiont+θ)+∑bk*sin(k*wHRT+ φ), wherein wmotionDirectly estimate from accelerometer signal (or another motion sensor signal).
Ambient light and the colour of skin
Ambient light and the colour of skin may make it difficult to the heart rate from PPG signal extraction users.When can be by being opened from PPG light sources The value for receiving detection optical signal subtract receiving the value for detecting optical signal and reducing the shadow of ambient light when PPG light sources are closed It rings (it is assumed that two signals were obtained in the time in close proximity to each other).
Can by change the intensity of PPG light sources, the light sent out from light source wavelength and/or by using corresponding to two not The ratio or difference of the received signal of co-wavelength and the influence for reducing the colour of skin.It can be inputted by using user (for example, user keys in Its colour of skin), the image of human face etc. determines the colour of skin, and then then can come calibration algorithm, light-source brightness, light source using the colour of skin Wavelength and receiver gain.It can also be by the way that will there is the signal of known amplitude to be sent to light source and then measure from photoelectric detector The signal received measures influence of the colour of skin (and compactness of user's wearable device) to original PPG signals.Such signal can It sends to reach the extended time cycle (to capture data via multiple expected heartbeats) and be then averaging and be not dependent on generating The stable state data group of heart rate.This amplitude can be determined then to algorithm calibration, hair compared with the class value being stored in table Emitter amplitude and receiver gain.
Estimate to improve using the heart rate of heuristic
After the initial estimation (for example, the peak counting estimated by power spectral density) for obtaining heart rate, it can be used for Boundary is applied to the permissible rate of heart rate.It can be for these boundaries of each user optimization, because each user will have uniquely Heart rate overview.For example, its sitting heart rate can be estimated when each user is fixed, and when this can be used as user's walking Lower limit.Similarly, the half of the walk frequency such as calculated from pedometer may act as the good lower limit for being expected heart rate.
Algorithm of heart rate can customize for each user, and can learn user heart rate overview and suitable for user behavior and/ Or characteristic is so as to expressively more preferable over time.For example, the algorithm can be right based on historical data from the user Heart rate or walking rate during given body activity set boundary.This can be broken in heart rate data by noise and/or motion artifact Bad when, provides better result.
HR quality metrics
In another example embodiment, the signal quality metrics of heart rate/PPG signals can be used to provide the standard of produced signal The quantization of exactness/accuracy.Depending on this measurement value, determine user heart rate (or such as breathing other PPG export degree Amount) algorithm can take certain actions, including allow user tense watchband, ignore collected heart rate data certain parts (for example, Data segment with low quality metric), and certain parts of heart rate data are weighted (for example, with better quality measurement Data can give bigger weight when calculating heart rate).
It in one embodiment, can following sending out signals quality metric:Scatter diagram is drawn, wherein x-axis is time, and y-axis For the frequency of the peak value in the PPG signals of that given time.Being using this strategy problem to be overcome can in given time There can be multiple and/or zero peak value.Line of best fit captures linear relationship in this scatter diagram.High-quality signal should have good It is fitted to one group of peak value of line (in short time span) well, and bad signal will be with cannot well be described by line one Group peak value.Therefore, the good measure of the quality of the fit quality offer PPG signals itself of line is provided.

Swimming tracking
In some embodiments of biometric tracks of device, biometric tracking may include algorithm of swimming, available From one or more motion sensors, altitude sensor (for example, barometric pressure sensor), orientation sensor (for example, magnetic Power meter), the data of location-based service sensor (for example, GPS, radio triangulation) and/or temperature sensor.The sensor can In Qian Ru An Installed to the single device of such as wrist.In other embodiments, additional sensors device could attach to swimmer's Forehead, the rear portion of head, goggles, the back of the body, hip, shoulder, thigh, leg and/or foot.
Three potential function components of swimming exercise analysis are as follows:
● stroke count detection --- the stroke per one way is provided and is counted, wherein one way is defined as from the one end in pond to opposite The unidirectional of end passes through.
● stroke classification of type --- the stroke type of description user is (for example, crawling, breaststroke, backstroke, butterfly stroke, breathing arm, stepping on Water (kicking without stroke) directly draws (body streamline), etc.), and can be any one of the following Or combination:
A. the classification for each stroke that user uses
B. the classification of the main stroke type of each complete single trip use.
C. the stroke that each score one way (such as the freestyle swimming of half one way, breaststroke of half one way) uses The classification of type
● one way counts --- the one way that user passes through counted.Determine that a method of one way is used by detecting When family is turned round in pond.
Turn round the 180 degree change for being defined as direction of advance.Detect turn round when, the beginning and end of deducibility one way. Some place (usually at one end or other places) before starting again at swimming in pond suspends (without fortune within the sometime period It is dynamic) it is considered as turning round, as long as subsequent direction of advance is opposite with the direction of advance before pause.
In some embodiments, these function components can be combined in a manner of numerous.
Algorithm structure
Swimming exercise analysis can be executed successively, parallel or to mix order (combinations of some sequential blocks and some parallel frames) Three function components.
Sequential grammar (see Figure 15 A)
In one embodiment, can original and/or pretreated sensor be analyzed by stroke detector algorithm first Signal.The time peak value in motion sensor (for example, accelerometer, gyroscope) can be used in stroke detector algorithm, and (part is most Big value and/or local minimum) as the instruction for having taken stroke.Then, can also it apply one or more heuristic rules to move Except the peak value for being not offered as stroke.For example, the magnitude of peak value, the time gap of two neighbouring peak values, peak value shake to peak value The morphological character (for example, clarity) of width and/or peak value may indicate that certain peak values are not offered as stroke.When sensor offer is one-dimensional When above data (such as 3 axis accelerometers or 3 axis movement sensors+altimeter (amounting to 4 number of axle evidences)), it is contemplated that all Whether the sequential and sizes related of the peak value on axis are to be generated by stroke with the peak value on one or more of described axis of determination.
If observing the single peak value for indicating stroke or a group peak value from the multiple data axis for indicating stroke, It can be from detecting previous peak and detecting that the data segments that the time between present peak value obtains extract feature.Feature includes But it is not limited to the maximum and ripple number in minimum value, section, the power that is measured in various measurements is (for example, L1 power and L2 Power, standard deviation, average), etc..The feature extracted can be then subjected to machine learning system, wherein off-line calculation system Number (supervised learning) or the adaption systems coefficient (unsupervised learning) when user uses biometric monitoring arrangement.Machine learning system System can return to stroke classification then for each stroke detected.
Turn round detector algorithm can by calculating derivative, (sensor includes to sensor for rolling average and/or use But be not limited in the present invention those of listed sensor) the high-pass filtering of signal carry out suddenly change in searching moving.May be used also And/or Principal Component Analysis (PCA) alternatively is executed to signal.If a main component, can be true different from next Surely generation is turned round.Such as the coefficient all or in part of the transformation such as Fast Fourier Transform (FFT) also is used as feature.Also it can be used Such as self returns the parameter models such as (AR) model.Can then use linear prediction analysis (LPA), least means square (LMS), Recursive least-squares filter (RLS) and/or Kalman Filter Estimation time-varying model parameter.Then compare the model parameter of estimation with It determines and whether there is suddenly change in its value.
In one embodiment, the skill level of swimmer and/or swimming pattern (for example, speed) can be from sensing datas Inferred, and is then used to turn round detection.For example, advanced swimmer is usually with stronger stroke (that is, big adds Speedometer peak magnitudes), and an one way is completed using less stroke.Therefore, estimate the skill level or characteristic of swimmer Measurement can be used for turning round detection algorithm.These measurements may include, but are not limited to mean motion signal or integrated in motor message Motor message, it is manifestly that, arm movement, estimation forward speed and the detection pattern of advanced swimmer.It can also be inputted via user Come the skill level for determining swimmer or other characteristics.For example, user can input it and swim for advanced, intermediate or beginner Person.
One from these analyses or many (combination) features can be used to detection data-oriented sample and/or adjacent data Whether sample, which has, is turned round characteristic.To obtain the optimal combination of feature and decision boundary, machine learning techniques can be utilized, such as Logistic regression, decision tree, nerve net, etc..
In some embodiments, it is turned round if detected, swimming data increase naturally from it can summarize and previously turn round, Such as stroke number, for each stroke and for the stroke type of one way, split time, etc..It is turned round if be not detected, So renewable stroke counter and type.Except non-user stops swimming, otherwise algorithm can return to stroke count detection.
Parallel method (see Figure 15 B)
In parallel method, some or all of three functional units can be performed in parallel.It for example, can be jointly It executes stroke type detection and turns round detection, and operate independently from stroke count detection.
In these embodiments, two functional groups of implementation in stroke type and the single algorithm turned round can be detected at the same time Part:Stroke type and turn round detection.For example, stroke type is (for example, detect the movement of freestyle swimming, breaststroke, backstroke, butterfly stroke Analysis) and turn round type (for example, flip turn (tumble turn), flip crawl turn (flip turn), two hands touch) Grader can return to detected stroke type or detected turn round type.During detection, can extract the time and Spectrum signature.Moving window can be initially applied to multiple data axis.The statistic of this window section can then be calculated, that is, maximum And the number of the ripple in minimum value, section, the power that is measured in various measurements are (for example, L1 power and L2 power, standard deviation Difference, average).Independent component analysis (ICA) and/or Principal Component Analysis (PCA) can equally be applied to find preferably to indicate Turn round any hiding signal of type and stroke similar properties.It then (potentially can improve) signal from this to indicate to calculate the time Feature.It, can be using various nonparametric filters solutions, low-pass filtering, bandpass filtering, high-pass filtering to enhance for temporal characteristics Need characteristics of signals.
Also the spectrum analysis such as FFT, wavelet transformation, Hilbert (Hilbert) transformation can be applied to this through windowing Section.Transformation coefficient may be selected to be feature all or in part.Such as AR, rolling average (MA) or ARMA can be used, and (self is returned And rolling average) model parameter model, and can be via auto-correlation and/or partial auto correlation or LPA, LMS, RLS or Kalman Filter finds the parameter of this class model.The all or part of estimated coefficient can be used as feature.
The rolling average window of different length can be run parallel, and provide feature listed above, and can also be by the feature All or part be used as feature.
Can machine acquistion coefficient (supervised learning) be then applied to these extracted features.It can train and then use one Or multiple machine learning techniques, i.e. multiple layers (for example, logistic regression) of binomial linear discriminant analysis, multinomial logic are returned Return, nerve net, decision tree/forest or support vector machines.
As window of interest moves, feature is can extract, and the feature of these new extractions will be returned via machine learning system It returns stroke type or what is detected turns round.
Stroke detector algorithm can independently of stroke type and turn round detection and run parallel.It can be examined by heuristic rules Survey and select the time peak value of original or prefiltered sensor signal.
Algorithm the summary stage (in the stage, it may be determined that, display and/or store measurement about swimming), can After-treatment applications in the sequence stroke type and are turned round into detection.It, can be together with if turned round with the confirmation of a certain confidence level Detected stroke, which counts, summarizes from the swimming metric data previously turned round.If unconfirmed turn round, rolling average Window can proceed with.Until user stops swimming, algorithm can continue to update the swimming measurement of the exercise about user, including but not The stroke being limited in the sum turned round, the sum of one way, the average stroke number total, per one way of stroke, the last one one way The change of number, every one way stroke number, etc..
Mixed method (see Figure 15 C and 15D)
In mixed method, stroke type and stroke count detection can be concurrently run, is followed by and turns round detection.
Stroke type detection can return to stroke type via the coefficient of machine learning.The desirable sensing of first movement window The segment of device signal.Then it can extract the entire feature of feature moving window feature listed herein either Subset.Then machine learning coefficient, training can be applied to the feature to determine which stroke type generates sensing offline The given segment of device signal.
Stroke count detection can simultaneously be run together with stroke type detection.
Once detecting stroke type and counting, inspection can be turned round to execute with the subset of cited entire feature or feature It surveys.
It is turned round if detected, the swimming that the completion of a circle can be recorded in user is summarized in measurement.Mistake after can inciting somebody to action Journey is applied to the stroke type detected to determine the stroke type most outstanding of completed circle.Subsequent algorithm, which can be moved into, to be drawn Dynamic type and count detection stage, except non-user stops swimming.It is turned round if be not detected, the algorithm can continue to update When the stroke type of front ring and counting, until being turned round until detecting.

Using user, there are the savings of the screen power of sensor
Portable biometric, which measures monitoring arrangement, to have one or more displays to present information to user.In a reality It applies in example, the sensor on biometric monitoring arrangement can determine that user is just using biometric monitoring arrangement and/or wearing life Object measures monitoring arrangement to determine the state of display.For example, the biometric monitoring arrangement with PPG sensors can make Use PPG sensors as proximity sensor to determine when user wears biometric monitoring arrangement.If user adorns oneself with Biometric monitoring arrangement, then the typicalness that can turn off from it of the state (for example, color LCD screen) of screen change to " on " or " for use ".
Power relative to satellite-based position determination system is saved
In some embodiments, the certain systems being included in biometric monitoring arrangement may be monitored with biometric Other systems in device are compared to the relatively large amount of power of consumption.It is attributed to the small space of many biometric monitoring arrangements about Beam, this can seriously affect the overall cell charge life of biometric monitoring arrangement.For example, it is monitored in some biometrics In device, it may include satellite-based position determination system.GPS is come from whenever being used using satellite-based position determination system When the data of satellite group obtain positioning, the power drawn from biometric monitoring arrangement battery is used.Biometric monitors Device can be configured to change satellite-based position determination system based on one or more biographies from biometric monitoring arrangement The data of sensor obtain the frequency of positioning.This adaptive location frequency functionalities can help power saving while still allow satellite-based Position determination system provides positioning with useful interval (in due course).
For example, if biometric monitoring arrangement has ambient light sensor, it can be used and passed from ambient light The data of sensor determine whether illumination condition indicates that biometric monitoring arrangement may be indoors rather than in outdoor.If Interior, then biometric monitoring arrangement can cause location frequency to be set to seems instruction biometric less than in illumination condition The level of monitoring arrangement workable location frequency at outdoor.There is the when of reducing biometric monitoring arrangement indoors to be tasted for this The effect of the positioning number of examination, and be therefore less likely to obtain good location using satellite-based position determination system.
In another example, if the pendant of the motion sensor instruction biometric monitoring arrangement of biometric monitoring arrangement Wearer is substantially fixed, such as sleeps or do not move substantially more than several feet per minute, then satellite-based position is true Wearer's (example during exercise that biometric monitoring arrangement is indicated than motion sensor can be set to by determining the location frequency of system Such as, from a position walking or running to another location, for example, mobile be more than several feet) the case where low level.
In a further example, actually whether biometric monitoring arrangement can be configured to determine biometric monitoring arrangement It is worn by people, if it is not, so location frequency can be set to than biometric monitoring arrangement reality by biometric monitoring arrangement The low level of the case where being worn on border.It can be for example in the exercise data collected from the motion sensor of biometric monitoring arrangement Indicate that biometric monitoring arrangement is substantially fixed (for example, even in the when biometer for showing wearer's sleep or sitting Amount monitoring arrangement undergo it is small mobile when it is also not fixed) when or for example from heart rate sensor data instruction do not detect To these determinations for carrying out whether being worn about biometric monitoring arrangement when heart rate.For optics heart rate sensor, if Light source switches and exist in the light quantity that light detecting sensors detects when turning off it is few change, then this may indicate that following thing It is real:Heart rate sensor does not compress the skin of people, and infers that biometric monitoring arrangement is not worn.This is adaptive satellite-based Position determination system location frequency concept is discussed in more detail No. 61/955,045 U.S. filed in 18 days March in 2014 and faces When patent application case in, the U.S. provisional patent application cases are previously to draw in " to the cross reference of related application " part Mode is incorporated herein and is saved hereby about the power in the context of satellite-based position determination system again Content that place points out and be herein incorporated by reference.
It should be understood that other than the feature comprising discussed in further detail below, biometric monitoring arrangement also may include above One or more feature or functions discussed or discussed in the various application cases being incorporated by reference above in discussing.These Embodiment is interpreted as within the scope of the invention.
Although discussed above concentrated on a variety of different systems that may include in biometric monitoring arrangement and functionality, But discussion subsequently below concentrates on some specific embodiments in more detail (some of them may also be discussed above).
Automatic detection is not worn and the heart rate monitor of wearing state
Some embodiments are provided for operating the heart rate monitor of wearable body-building monitoring arrangement to measure heartbeat waveform The method of one or more characteristics." heartbeat waveform " refer to as used herein by user heartbeat drive blood flow cause or The variation for the relevant any measuring signal of blood flow that heartbeat with user drives.In some embodiments, measuring signal and the heart Dirty pump blood passes through the blood circulation caused by the circulatory system related, causes painstaking effort in capillary volume or other parameters The variation of pipe driving.In some embodiments, heartbeat waveform is measured by photoelectricity volume diagram (PPG).In these embodiments, The blood volume that heartbeat waveform reflects in capillary changes, heartbeat and pulsation (arteriopalmus as caused by heartbeat) phase with user It closes.In some embodiments, measuring signal is related with the muscle activity of heart or ECG signal.In some embodiments, the heart Dirty work is dynamic or signal can be measured by ECG to obtain heartbeat waveform.
Heartbeat waveform indicates that (it corresponds to complete since being generated to next heartbeat heartbeat one or more heartbeats cycle Heartbeat) information.The frequency of cardiac cycle is described by heart rate, is typically expressed as bounce number per minute.Heartbeat waveform usually wraps Amplitude, frequency and/or the shape of waveform in information containing the various stages about heartbeat, such as one or more heartbeats cycle. In many examples, heartbeat waveform is obtaining the heart rate of user.
In some embodiments, optics heart rate monitor can be used in wearable device, by sending out light pulse and in light With the skin of user or it is other tissue interact after detection light and implement different operation modes, thus capture can be used to acquisition user Heartbeat waveform, wearing state, user personality etc. data.
In some embodiments, the present invention is provided to monitor dress in the wearable body-building with heart rate monitor (HRM) It sets when determining described device is not worn by the user (or when being embodied as weared on wrist formula device be " outside wrist ") in low power state The method of middle operation described device.This feature of HRM is also known as " being automatically closed (automatic off) " function.In some realities It applies in example, automatic closing function is to be implemented by operating HRM in " not wearing " (or " outside wrist ") detection pattern, and close automatically It closes function and automatically turns off the heart rate monitor operation of HRM in the case where device determines that it is not worn by the user to save energy. Other benefits of automatic closing function include to provide more accurate heart rate estimation.For example, when execution is automatically closed or automatically When opening (described below), heart rhythm detection algorithms can reset.In one embodiment, algorithm stops fortune when detecting outside wrist Row, and restart when detecting on wrist.When heart rate monitor restarts, reset.
In some embodiments, the present invention is provided in the wearable body-building monitoring arrangement determination with heart rate monitor It is operated in normal power state when described device wears (or when being embodied as weared on wrist formula device be " on wrist ") by user The method of described device.This feature of HRM also known as " automatically turns on " function.In some embodiments, automatically turning on function is Implemented by operating HRM in " wearing " (or " on wrist ") detection pattern.Automatically turn on function device detect movement and Determine automatically make in the case that it is worn by user HRM exit low power state and open HRM heart rate monitor operate.
In some embodiments, do not wear (or outside wrist) and wear (or on wrist) detection can by light (for example, LED) detect Lai Implement, send out light pulse and detects signal after light pulse is interacted with the skin of user and tissue.In some embodiments, Some hardware, firmware, the software of the analysis that detection can be shared for light emitting, light detection and detected signal are not worn and worn And/or parameter.In other embodiments, two detection modes use light emitting, the light inspection that can be used for not wearing and wearing detection Different hardware, firmware, software and/or the parameter surveyed and analyzed.
In some embodiments, wearable body-building monitoring arrangement is entered into and exited from by probe light (for example, LED) and movement inspection The low power state that device is adjusted is surveyed, so that implementation is automatically closed and open function.In low power state, heart rate monitor passes through Turn off or be scaled down the operation of its LED light source and its photoelectric detector and saves power.In some embodiments, Qi Taguang Source and photodetector (for example, photodiode, photomultiplier, CCD or CMOS) can be used to implement to be automatically closed or open work( Energy.Figure 17 A show this embodiment, wherein identical spy light-measuring mechanism to determine heart rate monitor by wearing (" on wrist ") still Not by wearing (" outside wrist ").In the other embodiments being described below, two different light-measuring mechanisms of visiting can be used to determine monitor Wrist on the outer state of state and wrist.As those skilled in the art will understand, although heart rate monitor as described herein describes To be worn in the wrist of user, but other types of embodiment allows user to wear heart rate monitor in an alternative form, Such as it is worn on ankle or the chest of user.In these embodiments, wearing state is corresponded respectively to non-wearing state " state on wrist " and " outside wrist " state of hereinafter describe embodiments.
As shown in figure 17 a, LED or another light sources, which are sent out, (to be also known as wearable dress by wearable body-building monitoring arrangement Set) heart rate monitor photoelectric detector detection light pulse.In general, when device is worn by user, it is light emitted will be with The skin of user and/or the interaction of other tissues, and then detected by the photoelectric detector of heart rate monitor.If device not by with Family is worn, then light emitted to be detected by photoelectric detector, or will be detected with varying strength or pattern dynamic.It is detected Light difference provide heart rate monitor can analyze with determining device whether the data worn by user.See frame 1702.It is retouched in this place In the embodiment painted, because wearable body-building monitoring arrangement determines that it is worn in wrist, therefore it is maintained at optical detection behaviour In operation mode.If cardiac monitor determines that wearable device is not worn by the user, such as detects the outer state of wrist, then heart rate Monitor is switched to low power state, and wherein it does not send out or detect light pulse, therefore saves on the electric power of wearable device.See frame 1704.Here in discribed embodiment, wearable device can be held in low power state or return to optical detection shape State, this can be adjusted by the movement of user.Here in discribed embodiment, if heart rate monitor is in low-power shape In state, then it keeps in the case where movement is not detected in such state.However, when detecting movement to indicate When user may wear wearable body-building monitoring arrangement, optical detection state is returned to.The low power state of this motor adjustment is kept away Exempt to need to adjust heart rate monitor using light source and photodetector, to realize that further power is saved.Wear detection pattern Motion detection can be implemented by being suitable for any one of motion detector of wearable device as described above.Citing For, motion detection can algorithm static by the Data Detection caused by the motion sensor or movement implement.Another example can Using the intrinsic interruption of motion sensor for waking up sensor, it can trigger and wear detection.
In Figure 17 A in discribed embodiment, heart rate monitor can execute 1702 discribed optical detection of frame at it Heart rate or other heartbeat waveform coherent signals are measured while function.1702 described optical detection mechanism determines heart rate monitor Whether should be held in optical detection pattern and continue to execute cardiac monitoring function.Same light detection agency also determines heart rate monitor Whether optical detection and heart rate monitor should be exited.As shown in Figure 17 B, individual optical detection mechanism can be used for outside wrist detecting (to move back Go out PPG heart rate monitors) and wrist on detection (with enter PPG heart rate monitors).
In some embodiments, as described in the frame 1708 of Figure 17 B, the optical detection pattern for detecting " wrist " state Can relatively low intensity send out light pulse reach certain time percentage.If the skin of light and user that light source is sent out or its It organizes interaction, then reflection or scattering light will be detected by the photoelectric detector of heart rate monitor.When this occurs, heart rate prison Visual organ enters such as 1706 discribed normal power state of frame.When this does not occur, heart rate monitor continuation optical detection reaches specific Time cycle.If the specific time period pass by and not by optical detection detect user interact, wearable device into Enter such as discribed low power state in frame 1710.
Heart rate monitor in normal power state, which executes heart rate monitor function and wears, detects both detecting functions, As shown in frame 1706.In some embodiments, in the optical detection mechanism for not wearing detection of frame 1706 and frame 1708 The optical detection mechanism of wearing detection compares can be with relatively high power operation.In some embodiments, 1708 function is at two Implement in state:State is into a fashionable function outside wrist, and from wrist state into fashionable different function.It hereafter will more in detail This embodiment carefully is described.In other embodiments, similar light pulse can be used for detecting the transformation that do not wear and for detecting To the transformation of wearing.In some embodiments, different analyses can be applied to not wear detection or wear detection.For example, not Wearing detection can be triggered by the certain strength changing pattern of detected light pulse, and wearing detection can be by the strong of detected light pulse Degree triggering.The transmitting of the light pulse for not wearing/wearing detection and the example of detection is discussed further below.
1706 optical detection mechanism can determine whether BMD is that wrist is outer (or not wearing).If it is not, so it is maintained at just Normal power rating is to execute heart signal monitoring.If detecting the outer state of wrist, stops PPG heart rate monitors, exit just Normal power mode and the optical detection pattern for being back to frame 1708.Up to spy in the optical detection pattern that wearable device has been in 1708 Fixed cycle and be not detected after wearing, wearable device enters the lower power state of frame 1710.Wearable device is not being examined It is maintained in lower power state in the case of measuring user movement.If detecting user movement, 1708 are returned to Optical detection state.
The process chart of Figure 18 A displayings according to some embodiments of the present invention, wherein wearing with heart rate monitor Body-building monitoring arrangement is worn to operate in different mode in a manner of having energy benefits.In various implementations as described further below In example, heart rate monitor by using such as light sources such as one or more LED send out light pulse and its with the skin of user or its It organizes detection light after interacting and is operated in different mode.It is described further below and sends out and detected light pulse Characteristic.
Here in discribed embodiment, wearable body-building monitoring arrangement is started by the movement of detection device.Such as Movement is not detected in fruit, then device is held in motion detection mode.See frame 1802.If device detects movement, It starts the operation heart rate prison in being configured to detection device and never wearing " the wearing detection pattern " for be converted to wearing state Visual organ.Operation in second mode may include by light source (for example, LED) make light pulse and light and user skin and/ Or detection light after tissue interaction.See frame 1804.Within the defined time after entering second mode, device determines that heart rate is supervised Whether visual organ detects that device has been converted to wearing state.See frame 1806.If not provided, so device terminates to wear detection mould Formula is shown in frame 1807, and returns to the motion detection operations of frame 1802.If device detects the transformation of wearing state, It starts to operate heart rate monitor in the first mode of the heartbeat waveform or other heart coherent signals that are configured to measurement user Device.See frame 1808.
The second mode of frame 1804 corresponds to the wearing detection pattern as described in elsewhere herein.The one of Figure 18 A In a embodiment, can be configured to detect the second mode phase of the transformation of non-wearing state as shown in frame 1810 Same mode is implemented to wear detection pattern.Alternate embodiment related with Figure 18 B described below is by wearing detection pattern and not It wears detection pattern and is embodied as two different modes.
When being operated in first mode of the heart rate monitor in frame 1808, the light arteries and veins interacted with the tissue of user is detected Punching, to capture the signal intensity as caused by heartbeat related blood stream amount in the capillary of user.In some embodiments, heart rate Monitor can measure other information related with heartbeat waveform as described above.Meanwhile device is periodically and temporarily Operation heart rate monitor is converted to non-wearing state from wearing state with detection device in a second mode, while also first Operation is to detect heart rate in pattern.See frame 1810.When heart rate monitor operates in a second mode, whether device determining device It has been converted to non-wearing state, has seen frame 1812.If not, so its continuation operates in first mode and second mode the two, As described in frame 1810.If it is then device terminates to monitor the first mode of heartbeat waveform signal.See frame 1814.At this point, Device makes heart rate monitor back to being operated in the motion detection mode of frame 1802.
The process chart of Figure 18 B shows according to some embodiments of the present invention.The process of Figure 18 B is similar to Figure 18 A's Process, but emphasis is slightly different, second for detecting the first mode of heart signal and for detecting non-wearing state Operation starts while pattern.See frame 1822, can correspond to the frame 1810 of Figure 18 A.The process of Figure 18 B is for automatically turning off The detection of not wearing of heart rate monitor (see the second mode in frame 1822) (is detected with heart rate monitor is opened see the wearing in frame 1832 Pattern) wearing detection implement two different modes.In some embodiments, same mechanism can be used for the process of Figure 18 A The degree of approach of detection and user's body is to open (see the wearing detection pattern of frame 1804) and turn off heart rate monitor (see frame 1810 Second mode).
During shown in Figure 18 B, wearable device operates heart rate monitor to detect heart rate in the first mode Or other heartbeat waveform characteristics.Meanwhile heart rate monitor is operated in a second mode to detect user's degree of approach.See frame 1822. Here in discribed embodiment, implements second mode and do not worn (or outside wrist) with determining whether heart rate monitor has been converted to State.See frame 1824.If device is not yet converted to non-wearing state, device continues in the operation of frame 1822 first Heart rate monitor is operated in pattern and second mode the two.If heart rate monitor, device are not worn in second mode determination Automatically stop heart rate monitor operation in the first mode.See frame 1826.This operation contribute to by device not by with Automatically turn off heart rate monitor when wearing and save energy in family.In some embodiments, device, which enters, does not monitor heart rate or spy Survey the low-power shape of user's degree of approach (also stopping second mode operation further to save energy, do not shown in the flow chart) State.
During discribed in Figure 18 B, wearable device is held after the first mode for stopping heart signal monitoring Row motion detection, the motion detection provide the triggering for automatically opening heart rate monitor function if necessary.See frame 1828.Such as this In text mentioned by other places, motion detection can be by different hardware and software implementation.If movement is not detected, device is protected It holds in low power state.See frame 1830.If detecting movement, the possibility that instruction user interacts with device, then filling It sets beginning and is being designed to whether determining device operates in the wearing detection pattern that may be worn by user.See frame 1832.If The wearing detection pattern of heart rate monitor determines that it is not worn, then device returns to motion detection mode.However, such as core Rate monitor determining device is worn by user, then device returns to the operation of frame 1822 to operate the heart in the first mode simultaneously Rate monitor is to detect heartbeat and operate heart rate monitor in a second mode to detect user's degree of approach (to non-wearing state Transformation).See frame 1834.It is described although should be understood that the starting point and end point of device operation is presented in the description of Figure 18 A and 18B Process is sustainably implemented, and can start and terminate at any moment in disclosed flow chart.In some embodiments, when User's manual ON and when turning off device, into starting and end point.
