Biosensor
The biometric monitoring arrangement discussed herein can use one, some or all of with lower sensor to obtain physiological data, including but not limited to the physiological data summarized in following table.All combinations of biosensor and/or physiological data and arrange set falling within the scope of the present invention.Biometric monitoring arrangement can including but not limited to following appointment for obtaining one of corresponding physiological data, the type of some or all of transducer; In fact, also can or alternatively use the transducer of other type to obtain corresponding physiological data, and the transducer of this other type a little is also set falls within the scope of the present invention.In addition, biometric monitoring arrangement can export statistical conversion physiological data from respective sensor, but is not limited to number or the type of the physiological data that it can be derived from described transducer.
In an example embodiment, biometric monitoring arrangement can comprise optical pickocff to detect, sensing, sampling and/or produce can in order to determine to represent the data of the information of the anxiety (or its level) of such as user, blood pressure and/or heart rate.(see, such as Fig. 2 A to 3C and 11A to KKG).In this little embodiment, biometric monitoring arrangement can comprise optical pickocff, it has one or more light source (LED, laser, Deng) to send or to export the health of light to user, and photodetector (photodiode, optotransistor, Deng) provide to determine to represent the data of the data of the anxiety (or its level) of user, blood pressure and/or heart rate (such as, such as, by using photoelectricity volume diagram) to sample, to measure and/or to detect this light from the response of user's body or reflection.
In an example embodiment, the heart rate measurement of user can be triggered by the criterion determined by one or more transducer (or being connected to its treatment circuit).For example, when the data from motion sensor indicate static or cycle that is that have few motion, biometric monitoring arrangement can trigger, obtains and/or obtain heart rate measurement or data.(see, such as Fig. 9,12A and 12B).
Figure 12 A illustrates the example of the portable biometric metering monitoring arrangement of the telecommunication circuit having heart rate or PPG transducer, motion sensor, display, vibrating motor and be connected to processor.Figure 12 B illustrates the example of the portable biometric metering monitoring arrangement of the telecommunication circuit having heart rate or PPG transducer, motion sensor, display, vibrating motor, position transducer, altitude sensor, skin electric conductivity/humidity sensor and be connected to processor.
In one embodiment, when motion sensor indicating user is movable or move (such as, for triggering, obtain and/or obtain required heart rate measurement or data (such as, in order to determine the data of the resting heart rate of user) improper or and the motion of non-optimal) time, can be placed in order to the biometric monitoring arrangement and/or transducer obtaining and/or obtain required heart rate measurement or data or be held in low power state.Because the heart rate measurement during movement carried out may be not too reliable and may passive movement illusion destroy, thus when biometric monitoring arrangement at the volley time, the frequency (thus reducing power use) reducing to collect heart rate data sample may be needed.
In another embodiment, biometric monitoring arrangement can use the data of indicating user activity or motion (such as, from one or more motion sensor) adjust or revise triggering, obtain and/or obtain the characteristic (such as, to improve the robustness to motion artifact) of required heart rate measurement or data.For example, if biometric monitoring arrangement receives the data that indicating user is movable or move, so biometric monitoring arrangement adjustable or amendment are in order to obtain the sampling rate of transducer of heart rate data and/or resolution model (such as, when user movement amount exceedes a certain threshold value, biometric monitoring arrangement can increase sampling rate and/or increase the sampling resolution pattern of the transducer in order to obtain heart rate measurement or data).In addition, biometric monitoring arrangement can at the sampling rate of period in this little cycle (such as, user movement amount exceedes the cycle of a certain threshold value) adjustment of User Activity or motion or amendment motion sensor and/or resolution model.In this way, when biometric monitoring arrangement is determined or this User Activity or motion detected, motion sensor can be placed in higher sampling rate and/or higher sampling resolution pattern such as to realize the adaptive-filtering more accurately of heart rate signal by biometric monitoring arrangement.(see, such as, Fig. 9).
Fig. 9 illustrates the mobile degree that experiences based on biometric monitoring arrangement and changes the example of portable biometric metering monitoring arrangement that it detects the mode of user's heart rate.When motion (such as, via use accelerometer) being detected wherein, user can be thought in " activity " by biometric monitoring arrangement, and the motion artifact that reduces in heart rate measurement can occur high sampling rate heart rate detection.Can preserve and/or show this data.When biometric monitoring arrangement determine that user does not move (or sitting relatively), low sampling rate heart rate detection (it does not consume so much power) can be suitable for measuring heart rate and thus can be used.
It should be noted that, when biometric monitoring arrangement uses optical technology to come such as by using photoelectricity volume diagram to obtain heart rate measurement or data, motor message can be used determine or set up ad hoc approach or the technology of being carried out data acquisition or measurement (such as, synchronous detection instead of non-amplitude modulation method) and/or its analysis by heart rate sensor.(see, such as Figure 11 E).In this way, the data of indicating user motion or activity can cause biometric monitoring arrangement to be set up or adjust type or the technology of data acquisition or the measurement used by one or more optics heart rate sensor.
For example, in one embodiment, when motion detector circuit detect or determine the motion of biometric monitoring arrangement wearer lower than during threshold value (such as, if user's sitting or sleeping determined by biometric monitoring arrangement), biometric monitoring arrangement (or heart rate measurement technology adjustable as herein disclosed and/or reduce the sampling rate of optics heart rate sampling.(see, such as, Fig. 9).In this way, biometric monitoring arrangement can control its power consumption.For example, biometric monitoring arrangement by reducing sensor sampling rate and reduce power consumption, such as, biometric monitoring arrangement can every 10 minutes once or every 1 minute 10 seconds Di heart rate is sampled (via heart rate sensor).It should be noted that additionally or alternati, biometric monitoring arrangement can control power consumption via according to the treatment circuit analysis of motion detection control data and/or data analysis technique.Thus, the motion of user may affect heart rate data get parms and/or data analysis or its process.
Motion artifact in heart rate sensor suppresses
As discussed above, by using one or more algorithm to remove motion artifact to improve by the original signal of PPG sensor measurement.The movement of sensor measurement user (for determining motion artifact) can be used, described transducer including but not limited to accelerometer, gyroscope, proximity detector, magnetometer, etc.The target of this little algorithm uses from the movable signal of capturing as other transducer instructed to remove the component (mobile illusion) being attributable to movement of PPG signal.In one embodiment, sef-adapting filter can be used based on hybrid card Thalmann filter (Kalman filter) and least-mean-square filter or recursive least-squares filter to remove mobile illusion in PPG signal.Can then use peak counting algorithm or power spectral density algorithm for estimating from clean/extract heart rate through filtering signal.Or, Kalman filter or particle filter can be used to remove this little mobile illusion.
Can be Y=Y by heart rate signal model creation in order to calculate the other method of heart rate frequency dc+ ∑ a k* cosk θ+b k* sink θ, wherein k is the exponent number of harmonic component, and θ is the model parameter for heart rate.This model then can use extended Kalman filter or particle filter and be fitted to signal.This model utilizes following true: signal is also non-sinusoidal, therefore contains power at primary harmonic and multiple extra both harmonic waves place.
Or, can be Y=Y by signal modeling dc+ ∑ a k* sin (k*w motiont+ θ)+∑ b k* sin (k*w hRt+ φ), wherein w motiondirectly estimate from accelerometer signal (or another motion sensor signal).
Surround lighting and the colour of skin
Surround lighting and the colour of skin may make to be difficult to the heart rate from PPG signal extraction user.During by opening from PPG light source receive sensed light signal the value institute deducted when PPG light source is closed receive the value of sensed light signal and reduce the impact (assuming that two signals are the time acquisitions at close proximity each other) of surround lighting.
By the intensity changing PPG light source, the wavelength of light sent from light source and/or the impact reducing the colour of skin by using the ratio of the received signal corresponding to two different wave lengths or difference.Image etc. by use user's input (such as, user keys in its colour of skin), human face determines the colour of skin, and can then use the colour of skin to come calibration algorithm, light-source brightness, optical source wavelength and receiver gain subsequently.Also by the signal with known amplitude being sent to light source and then measuring the signal that receives from photoelectric detector to measure the colour of skin (and compactness of user's wearable device) to the impact of original PPG signal.This type of signal can send time cycle (so that via multiple expection heartbeat capture data) of reaching prolongation and then be averaging to produce the stable state data group not depending on heart rate.Can then by this amplitude compared with the class value be stored in table to determine that algorithm is calibrated, reflector amplitude and receiver gain.
The heart rate of heuristic is used to estimate to improve
After the initial estimation (such as, the peak counting estimated by power spectral density) obtaining heart rate, it can be used for applying boundary to the allowed speed of heart rate.Can for these boundaries of each user optimization, because each user will have unique heart rate overview.For example, its sitting heart rate can be estimated when each user maintains static, and lower limit when this can be used as user's walking.Similarly, as calculated from pedometer 1/2nd of walk frequency can serve as expecting the good lower limit of heart rate.
Algorithm of heart rate can for each customization, and can learn the heart rate overview of user and be suitable for the behavior of user and/or characteristic to pass better expressively in time.For example, described algorithm can based on the historical data from user to the heart rate between given body active stage or walking rate setting boundary.This can provide better result when heart rate data is destroyed by noise and/or motion artifact.
HR quality metric
In another example embodiment, the signal quality metrics of heart rate/PPG signal can in order to provide the quantification of the accuracy/accuracy of produced signal.Depend on this value of measuring, determine that the algorithm of the heart rate (or other PPG such as such as breathing derives tolerance) of user can take some action, comprise and allow user strain watchband, ignore some part of collected heart rate data (such as, there is the data segment of low quality metric), and some part of heart rate data is weighted (data such as, with better quality tolerance can give larger weight when calculating heart rate).
In one embodiment, can sending out signals quality metric as follows: draw scatter diagram, wherein x-axis is the time, and y-axis is the frequency of the peak value in the PPG signal of that given time.This strategy problem to be overcome is used to be may there is multiple and/or zero peak value at given time.Line of best fit is capture line sexual intercourse in this scatter diagram.High-quality signal should have the one group of peak value being fitted to line (in short time span) well, and bad signal will have one group of peak value that can not be described well by line.Therefore, the good measure of the quality of PPG signal self is provided to the fit quality of line.
Sitting, sleep and activity classification tolerance
In another example embodiment, when device is determined user's sitting or be sleeping, biometric monitoring arrangement can use transducer to calculate changes in heart rate.Herein, biometric monitoring arrangement can higher rate sampling mode (relative to non-sitting cycle or the User Activity cycle exceeding predetermined threshold) operation sensor to calculate changes in heart rate.Biometric monitoring arrangement (or external device (ED)) can use changes in heart rate as the designator of health of heart or anxiety.
In fact, in certain embodiments, tensional level and/or the health of heart of user can be measured when user's sitting and/or sleeping (such as, as detected by biometric monitoring arrangement and/or determining) and/or determine to biometric monitoring arrangement.Some embodiments of biometric monitoring arrangement of the present invention can use instruction changes in heart rate, skin pricktest response, skin temperature, body temperature and/or heart rate sensing data to determine the tensional level of user, health status (such as, the risk of fever or flu, outbreak, or progress), and/or health of heart.In this way, the treatment circuit of biometric monitoring arrangement can be determined and/or " baseline " tensional level of following the tracks of the user passed in time and/or the heart " health " passed in time.In another embodiment, described device can wherein user without motion, (or the motion of user is lower than predetermined threshold, such as when user be just seated, lie down, sleeping or be in sleep stage (such as, deep sleep) time) one or more cycle during measure the physiological parameter of user.These data also can by biometric monitoring arrangement be used as nervous relevant parameter, health-related parameter (such as, the risk of fever or flu or outbreak), the response of health of heart, changes in heart rate, skin pricktest, skin temperature, body temperature and/or heart rate " baseline ".
Sleep watchdog

Fig. 7 describes the side that user presses portable biometric metering monitoring arrangement and carries out heart rate measurement with installing type optics heart rate detection transducer from the side.The display of biometric monitoring arrangement can show heart rate heart rate and/or display user whether being detected.
It should be noted that the data of a little optical pickocff since then can represent physiological data and/or environmental data.In fact, in one embodiment, optical pickocff provides, obtain and/or detect the information of the multiple sides from biometric monitoring arrangement, and whether tube sensor is not placed on one or many person in described multiple side.For example, optical pickocff can obtain the data relevant with the environment light condition of environment.
When optical pickocff is settled or be arranged in the skin side of biometric monitoring arrangement, in operation, light source in biometric monitoring arrangement can be luminous on the skin of user, and responsively, the photodetector sampling in biometric monitoring arrangement, acquisition and/or the correspondence reflection detected from skin (and from body interior) and/or the light that sends.One or more light source and photodetector can by strengthening or optimize signal to noise ratio and/or in order to reduce or to minimize the array of power consumption of described light source and photodetector or pattern is arranged.These optical pickocff samplings, acquisition and/or detection physiological data, described physiological data can then treated or analyze (such as, by resident treatment circuit) with obtain represent such as user heart rate, breathing, changes in heart rate, oxygen saturation (SpO 2), the data of blood volume, blood sugar, skin moisture and/or cutaneous pigmentation level.
Light source can send the light of one or more wavelength of the type specific to or be directed to physiological data to be collected.Similarly, fluorescence detector sampling, measurement and/or detect also specific to or be directed to the type of physiological data to be collected and/or one or more wavelength of (user's) physiological parameter that is to be assessed or that determine.For example, in one embodiment, send the light source (such as, sending the LED of the light of the wavelength had corresponding to green light spectrum) of the light of the wavelength had in green light spectrum and can provide with sampling, the photodiode of measuring and/or detect light is corresponding therewith response or reflection through location can in order to determine or to detect the data of heart rate.By contrast, send the light source of the light of the wavelength had in red spectral (such as, send the LED of the light of the wavelength had corresponding to red spectral) and send the wavelength had in infrared spectrum light light source (such as, sending the LED of the light of the wavelength had corresponding to IR spectrum) and can provide with sampling, the photodiode of response or reflection of measuring and/or detect this light through location can in order to determine or to detect SpO 2data.
In fact, in certain embodiments, color or the wavelength of the light sent by light source (such as LED (or one group of LED)) can correct, adjustment and/or controls according to the predefined type of obtained physiological data or operating condition.Herein, the wavelength of light that sent by light source of adjustable and/or control is to optimize and/or to strengthen " quality " of the physiological data being obtained by detector and/or sample.For example, when the skin temperature of user or ambient temperature lower time, the color of the light sent by LED can be switched to green from infrared ray to strengthen the signal corresponding to cardiomotility.(see, such as Figure 11 D).
In certain embodiments, biometric monitoring arrangement can comprise in shell window (such as, in order to temporarily examine, opaque window) to promote that the light between optical pickocff and user is launched.Herein, described window can be permitted on skin that light (such as, having selected wavelength) is issued to user by such as one or more LED and to be permitted the response of light or reflection via described window to back through to be undertaken sampling, measure and/or detecting by such as one or more photodiode.In one embodiment, the circuit relevant with sending and receive light can be placed in crust of the device inside and plastics or glassy layer (such as, being coated with infrared ray ink) or infrared lenses or filter (its permit infrared light by but the light disapproved in people's vision spectrum pass through) below or rear.In this way, the Transmission light of described window can not by human eye finding.
Biometric monitoring arrangement can use light pipe or other translucent construction to promote that light is transmitted into health and the skin of user from light source.(see, such as, Fig. 4 A is to 5).Thus, in certain embodiments, light can through a little light pipe thus or other translucent construction skin from light source oriented users.Scattered light from user's body can via identical or similar structures to the optical circuit returned in guiding biometric monitoring arrangement.In fact, the material that described translucent construction can use promotion low light to lose and/or optical design are (such as, translucent construction can comprise the lens promoting that light is collected, and the part usable reflectance material of translucent construction is coated with or is adjacent to reflecting material to promote the internal reflection of light in translucent construction), improve the signal to noise ratio of photodetector thus and/or promote to reduce the power consumption of light source and/or photodetector.In certain embodiments, light pipe or other translucent construction can comprise the material optionally launching the light (emission effciency is higher than the emission effciency of the light with other wavelength) with one or more specific or predetermined wavelength, serve as band pass filter thus.This quasi-belt ventilating filter can through tuning with the signal improving specific physiological data type.For example, in one embodiment, in-mold label or " IML " translucent construction can be implemented, wherein said translucent construction uses the material with predetermined or required optical characteristics to create specific bandpass characteristic, so that such as make infrared light by efficiency higher than the light (such as, there is the light of the wavelength in people's visible spectrum) with other wavelength.In another embodiment, biometric monitoring arrangement can use the translucent construction with optics opaque section (comprising some optical characteristics) and optical clear part (comprising the optical characteristics being different from optics opaque section).This type of translucent construction can provide via double injection or two step molding process, wherein optics opaque material and optically transparent material is injected into individually in mould.The biometric monitoring arrangement implementing this type of translucent construction can be depending on through the light direct of travel of translucent construction and comprises different optical transmission characteristics for different wave length.For example, in one embodiment, optics opaque material can reflect particular range of wavelengths more efficiently light is got back to photodetector (it can have the different wave length of the wavelength relative to sent light) from the health transmitting of user.
In another embodiment, catoptric arrangement can be placed in the visual field of optical transmitting set and/or photodetector.For example, the side with the skin that light is directed to user from optical transmitting set and/or the hole (or via perform this by way of the translucent construction of advancing) being directed to photodetector from the skin of user can cover in reflecting material (such as, chromium plating) to promote Transmission light.Reflecting material can increase then gets back to the efficiency of detector by light from light sources transmit to skin from skin transport.Available optical epoxy resin or other transparent material are filled reflectivity coating hole and are still allowed with low transmission loss transmitted light to prevent liquid access to plant main body simultaneously.
At enforcement translucent construction (such as, via IML create or formed structure) another embodiment in, this a little translucent construction can comprise the mask be made up of opaque material, and described opaque material limits one, the aperture of some or all of light source and/or detector.In this way, translucent construction optionally " defines " preferred volume of the user's body being transmitted into light or detecting from it light.It should be noted that and can use in conjunction with the concept described herein and/or illustrate or implement other mask configuration; Set falling within the scope of the present invention is configured in order to such as to improve photoelectricity volume diagram signal and to cover in conjunction with all this that concept that is described herein and/or that illustrate is implemented.

In certain embodiments, biometric monitoring arrangement can comprise concave surface or convex shape (such as lens) in the skin side of device, focuses on to make light and increases efficiency light being collected photoelectric detector from described point towards the designated volume at the certain depth place in skin.(see, such as, Fig. 4 A is to 5).When this type of biometric monitoring arrangement also uses light pipe with optionally and controllably route light, carry out moulding to the end of light-guiding pillar and make it have cylindricity to a certain degree (such as, nominally the end of light-guiding pillar can be the cylindrical surface (or its part) defined by the cylinder axis being parallel to skin side) can be favourable (such as, substituting the lens using axially symmetry).For example, in Wrist belt-type biometric monitoring arrangement, nominally this type of cylindrical lens can make cylinder axis be parallel to the forearm of wearer through orientation, this measure can have restriction and to enter the amount of this lens-like light from the direction of the forearm being parallel to people and increase the effect of the amount entering this lens-like light from the direction of the forearm perpendicular to people, because with the direction of being covered by bandage (namely, forearm perpendicular to user) compare, surround lighting more never may be arrived transducer surveyed area by the direction (namely along the forearm axis of user) that the bandage of biometric monitoring arrangement covers, light is reduced from the reflector efficiency be sent to user's skin or wherein " spuious " light that to be detected by photoelectric detector or collect simultaneously by increasing and improves signal to noise ratio by this type of configuration.In this way, the signal being sampled by photoelectric detector, measure and/or detect is made up of less stray light and more user's skin/health response (representing the signal to light emitted response or data) light emitted to this.
In another embodiment, light transmitting epoxy resin can be molded as concave surface or convex shape so that also for transducer provides useful optical characteristics.For example, during coating light transmitting epoxy resin, translucent construction more effectively can be coupled to through being shaped as concave surface to make light in the top of the translucent construction formed by described epoxy resin.

Swimming is followed the tracks of
In some embodiments of biometric tracking means, biometric is followed the tracks of can comprise swimming algorithm, it can utilize from one or more motion sensor, altitude sensor (such as, barometric pressure sensor), orientation sensor (such as, magnetometer), the data of location-based service transducer (such as, GPS, radio triangulation) and/or temperature sensor.Described transducer can embed in the single assembly being installed to such as wrist.In other embodiments, additional sensor apparatus can be attached to the forehead of swimmer, the rear portion of head, goggles, the back of the body, hip, shoulder, thigh, leg and/or pin.
Three potential function components that swimming exercise is analyzed are as follows:
Paddling count detection---provide the paddling of every one way to count, wherein one way is defined as and passes through to the unidirectional of end opposite from the one end in pond.
Paddling classification of type---the stroke type of user is described (such as, crawl, breaststroke, backstroke, butterfly stroke, breathing arm, tread (kicking without stroke), straight draw (body streamline), Deng), and any one or the combination that can be in following each:
A. the classification of each paddling of user's employing
B. the classification of the main paddling type of each complete one way use.
C. the classification of paddling type that uses of each mark one way (freestyle swimming of such as 1/2nd one way, the breaststroke of 1/2nd one way)
One way counts---the one way that user passes counted.Determine a method of one way when is turned round in pond by detecting user.
Turn round the 180 degree of changes being defined as direction of advance.Detect turn round time, the beginning of deducibility one way and end.Some place before again starting to swim in pond (usually at one end or other place) suspends (without motion within the cycle sometime) and also thinks to turn round, as long as direction of advance is subsequently contrary with the direction of advance before time-out.
In certain embodiments, numerous mode these function components can be combined.
Algorithm structure
Can successively, parallel or mix described three function components that order (combinations of some sequential block and some parallel frames) performs swimming exercise analysis.
Sequential grammar (see Figure 15 A)
In one embodiment, first original and/or pretreated sensor signal can be analyzed by paddling detector algorithm.Paddling detector algorithm can use time peak value (local maximum and/or local minimum) in motion sensor (such as, accelerometer, gyroscope) as the instruction taking paddling.Then, one or more heuristic rules can also be applied to remove the peak value not representing paddling.For example, the value of peak value, the time gap of two contiguous peak values, peak value can indicate some peak value not represent paddling to the morphological character (such as, definition) of peak amplitude and/or peak value.When transducer provides data (such as 3 axis accelerometers of more than one dimension, or 3 axis movement sensors+altimeter (amounting to 4 number of axle certificates)) time, can consider that the sequential of the peak value on all axles and sizes related are to determine whether the peak value on one or many person in described axle is produced by paddling.
If observe a group peak value of the single peak value of expression paddling or the multiple data axles from expression paddling, so feature can be extracted from data segments previous peak being detected and the time between present peak value that detects obtains.Feature including but not limited to the ripple number in maximum and minimum value, section, the power (such as, L1 power and L2 power, standard deviation, average) measured in various tolerance, etc.The feature extracted then can stand machine learning system, wherein calculated off-line coefficient of combination (supervised learning) or when user uses biometric monitoring arrangement adaption systems coefficient (unsupervised learning).The paddling that machine learning system can then detect for each returns paddling classification.
Turn round detector algorithm by calculating derivative, rolling average and/or using the flip-flop come the high-pass filtering of the signal of transducer (described transducer is including but not limited to those transducers listed in the present invention) in searching moving.Also and/or alternatively Principal Component Analysis (PCA) can be performed to signal.If a fundamental component is different from the next one, so can determine to turn round generation.Such as the coefficient all or in part of the conversion such as fast fourier transform (FFT) also can be used as feature.Such as oneself also can be used to return the parameter models such as (AR) model.Then linear prediction analysis (LPA), least means square (LMS), recursive least-squares filtering (RLS) and/or Kalman Filter Estimation time-varying model parameter can be used.Then the model parameter of estimation is compared to determine whether there is flip-flop in its value.
In one embodiment, the skill level of swimmer and/or swimming pattern (such as, speed) can be inferred from sensing data, and are then used in and turn round detection.For example, senior swimmer has stronger paddling (that is, large accelerometer peak magnitudes) usually, and adopts less paddling to carry out an one way.Therefore, estimate that the skill level of swimmer or the tolerance of characteristic can be used for turning round detection algorithm.These tolerance can including but not limited to mean motion signal or integrated motor message in motor message, and in particular, the arm of senior swimmer moves, estimate pace and detecting pattern.Skill level or other characteristic of swimmer also can be determined via user's input.For example, user can input it for senior, intermediate or beginner swimmer.
Can whether have and turn round characteristic in order to detect data-oriented sample and/or adjacent data sample from these of analyzing perhaps many (combination) features.For obtaining the best of breed of feature and decision boundary, can machine learning techniques be utilized, such as logistic regression, decision tree, nerve net, etc.
In certain embodiments, turn round if detected, data of so swimming naturally increase from can summarizing and previously having turned round, the number of such as paddling, for each paddling and paddling type, split time for one way, etc.If do not detect and turn round, so renewable paddling counter and type.Except non-user stops swimming, otherwise algorithm can get back to paddling count detection.
Parallel method (see Figure 15 B)
In parallel method, some or all in three functional units can be performed concurrently.For example, can jointly perform paddling type detection and turn round detection, and run paddling count detection independently.
In this little embodiment, can detect at the same time in paddling type and the single algorithm turned round and implement two functional units: paddling type and turn round detection.For example, stroke type (such as, detect freestyle swimming, breaststroke, backstroke, the mobile of butterfly stroke analyze) and the grader of turning round type (such as, flip turn (tumble turn), flip crawl turn (flip turn), two hands touch) can return detected paddling type or detected turn round type.Between detection period, can extraction time and spectrum signature.First moving window can be applied to multiple data axle.Then the statistic of this window section can be calculated, that is, the number of the ripple in maximum and minimum value, section, the power (such as, L1 power and L2 power, standard deviation, average) measured in various tolerance.Independent component analysis (ICA) and/or Principal Component Analysis (PCA) can be applied equally to find to represent better any hiding signal turning round type and paddling similar properties.Then signal indication feature computing time can from then on (be improved) potentially.For temporal characteristics, various nonparametric filters solutions, low-pass filtering, bandpass filtering, high-pass filtering can be applied to strengthen desired signal characteristic.
Also the spectrum analyses such as such as FFT, wavelet transformation, Hilbert (Hilbert) conversion can be applied to this through section of windowing.Conversion coefficient may be selected to be feature all or in part.The parameter model of such as AR, rolling average (MA) or ARMA (oneself returns and rolling average) model can be used, and the parameter of this class model can be found via auto-correlation and/or partial auto correlation or LPA, LMS, RLS or Kalman filter.Estimated all or part of of coefficient can be used as feature.
The rolling average window of different length can parallel running, and provides listed feature above, and also all or part of of described feature can be used as feature.
Then machine acquistion coefficient (supervised learning) can be applied to these and extract feature.Can train and then use one or more machine learning techniques, be i.e. multiple layers (such as, logistic regression) of binomial linear discriminant analysis, multinomial logistic regression, nerve net, decision tree/forest or SVMs.
Along with paid close attention to window moves, feature can be extracted, and the feature of these new extractions will return paddling type or turning round of detecting via machine learning system.
Paddling detector algorithm independent of paddling type and can turn round detection and parallel running.Detect by heuristic rules and select original or through the time peak value of pre-filtering sensor signal.
In the summary stage (in the described stage, can determine, show and/or store the tolerance about swimming) of algorithm, can by after-treatment applications in described sequence paddling type and turn round detection.If confirm to turn round with a certain confidence level, so can summarize from the swimming metric data previously turned round together with detected paddling counting.If turn round unconfirmed, so rolling average window can proceed.Until user stops swimming, algorithm can continue to upgrade to be measured about the swimming of the exercise of user, including but not limited to the change of the paddling number in the average paddling number of the sum of the sum of the sum turned round, one way, paddling, every one way, last one way, every one way paddling number, etc.
Mixed method (see Figure 15 C and 15D)
In mixed method, can run paddling type and paddling count detection concurrently, be turn round detection subsequently.
Paddling type detection can return paddling type via the coefficient of machine learning.The fragment of the sensor signal that the first moving window is desirable.Can feature be extracted subsequently, or the whole feature of moving window feature cited herein or subset.The off-line of machine learning coefficient, training can be applied to described feature subsequently to determine which paddling type produces the given fragment of sensor signal.
Paddling count detection side by side can be run together with paddling type detection.
Once paddling type and counting be detected, can perform by the subset of cited whole feature or feature and turn round detection.
If detect and turn round, the swimming being recorded in user that completes so can enclosed one is summed up in tolerance.Rear process can be applied to the paddling type that detects to determine the most outstanding paddling type of completed circle.Algorithm is movable to paddling type and count detection stage subsequently, except non-user stops swimming.If do not detect and turn round, so described algorithm can continue the paddling type and the counting that upgrade current circle, until detect and turn round.

In some embodiments, user can such as by mutual with equipment or by indicating them to sleep to set " sleep watchdog " pattern to equipment alternately with remote-control device (such as, smart phone).For example, in Fitbit Ultra and One, (can use after user wakes up same action indicating user no longer sleeping) indicates them to sleep to user by pressing single user interface button on this little device about 2 seconds.In some these type of embodiments, in order to indicating user, the same action (such as, pressing user interface buttons) of sleep also can be performed specific activities in order to indicating user, such as, will go jogging or by bike, namely stay up.In this little situation that the intentional user with equipment can indicate " sleep " or " activity " alternately, equipment is distinguished between " sleep " and " activity " by depending on the aid marks such as such as acceleration information.For example, if user and equipment are alternately to indicate " sleep " or " activity " and equipment detects subsequently and walks, runs or the mobile consistent acceleration of other " initiatively ", so equipment can determine wearer not in sleep.Compare, if user and equipment are alternately to indicate " sleep " or " activity " and equipment detects the acceleration with fixed position consistency subsequently, so equipment can determine that wearer falls asleep.
In some embodiments, about wearer whether the determination of sleeping can based on or when to be based in part on day.For example, at normal " sleep " time durations, such as afternoon, 9:00 was to 6:00 in the morning, and equipment can determine that wearer falls asleep.This determines to guide additionally by other data, and the acceleration such as measured by device sensor can be as discussed above sleeping consistent with the wearer of equipment.In some these type of embodiments, the intentional user mutual (such as, pressing user interface buttons as mentioned above) of wearer and equipment can be interpreted as when normal " sleep " time durations occurs to indicate " sleep " and can be interpreted as when normal " waking up " time durations occurs and indicate " activity ".Can be set as default standard with the time range of normal " sleep " time and normal " waking up " time correlation, such as afternoon, 9:00 was to 6:00 local zone time in the morning, or can adjust based on the pattern of wearer.For example, wearer can specify its normally sleeping time (people be on night shift can such as to equipment indicate its normally from the morning 8:00 to 4:00 sleep in afternoon) or equipment can to determine the normal sleep pattern (this determines also can remotely such as be made by the server from equipment receiving data a bit, and is provided to equipment subsequently) of wearer from historical data along with the time.Can use together to provide additional accuracy as some or all in the above the technology whether wearer of the equipment of biometric monitoring arrangement is sleeping for determining.
If select BR/EDR agreement in frame 2406, so described technology can proceed to frame 2408, and can use BR/EDR agreement transmitting data.If select BLE agreement in frame 2406, so described technology can proceed to frame 2410, and can use BLE agreement transmitting data between equipment and remote-control device.After data launch generation, the Bluetooth communication protocol selected in 2406 can be used further to excessive data, such as the second data, the 3rd data etc.Or, can make about whether utilizing BR/EDR agreement or BLE agreement to launch the independent decision-making of excessive data, that is, can for excessive data repeat block 2406.
The sleep state of the wearer of equipment can provide the data between equipment and remote-control device to launch the useful designator of the environment occurred within it.For example, if the wearer of equipment falls asleep, can be reasonably so hypothesis equipment by keep static reach certain time and therefore comparatively can not be in lose excessive risk that bluetooth connects and can use more slowly and more not the BLE agreement of power-intensive (if wearer wakes, so exist equipment will be in motion higher may and therefore bluetooth connect the high risk that can lose or interrupt, this may need transmitting data again and the electric power more than required situation may be caused to draw-can use in some cases higher bandwidth, higher-wattage BR/EDR agreement).

Technology 2500 starts in frame 2502, wherein has BR/EDR and BLE both equipment functional and can set up BR/EDR between self with another remote-control device and be connected.In frame 2504, equipment can be set up BLE and be connected between self with remote-control device, and therefore equipment can have and utilizes BR/EDR to connect or BLE connects as the selection of the potential data transmission path between equipment and remote-control device.Should be appreciated that, frame 2502 and 2504 can shown in order, with reversed sequence or also can completely or partially perform simultaneously.
As in technology 1800, at certain point, may wish such as from equipment to remote-control device, from remote-control device to equipment or both, transmitting data between equipment and remote-control device, such as the first data.Can make in frame 2506 about whether utilizing BR/EDR agreement or BLE agreement to carry out the decision-making of transmitting data.Whether the decision-making in frame 2506 can will be transmitted into remote-control device (contrary with from remote-control device to equipment) from equipment based on data is made.If data are sent to remote-control device from equipment, the decision-making using BLE agreement so can be made in frame 2506.If data are sent to equipment from remote-control device, the decision-making using BR/EDR agreement so can be made in frame 2506.
If select BR/EDR agreement in frame 2506, so described technology can proceed to frame 2508, and can use BR/EDR agreement transmitting data.If select BLE agreement in frame 2506, so described technology can proceed to frame 2510, and can use BLE agreement transmitting data between equipment and remote-control device.After data launch generation, the Bluetooth communication protocol selected in 2506 can be used further to excessive data, such as the second data, the 3rd data etc.Or, can make about whether utilizing BR/EDR agreement or BLE agreement to launch the independent decision-making of excessive data, that is, can for excessive data repeat block 2506.
The directivity that data are launched can be the useful designator of the data type of just launching.For example, if equipment is biometric monitoring arrangement, the most of data so from equipment to remote devices transmit may be the data of the sensor collection from equipment.This sensing data may not be time-critical, and therefore can be the candidate of lower bandwidth transmitting.This sensing data also can be continuous in essence, such as produce with little aturegularaintervals in all day, and the remote-control device receiving these data still can provide gross function, even if remote-control device not latest data, this also may show that this sensing data can be the candidate of lower bandwidth transmitting.By contrast, in some embodiments, the data being sent to equipment from remote-control device can be application data or real-time informing data, and therefore the transmitting of the higher bandwidth of data can be desirable.
For example, some equipment as biometric monitoring arrangement can take to have the form that integrated bio metering monitors the intelligent watch of transducer.This equipment can have the ability receiving " application program (apps) " from remote-control device." application program " can be non-initial and is stored in the program received from remote-control device on equipment but via bluetooth connection.Because program before can accessing from local memory the processor performed at all program files is not reliably work usually, the application program therefore downloading to equipment may be useless to the user of equipment before downloading completely.Therefore the wearer of equipment may wish to use higher bandwidth to connect by these data from remote devices transmit to equipment, because can wish to use described application program as early as possible usually after request set up applications.In some cases, notice can be transmitted into equipment by remote-control device, such as text message, Email, picture etc., and the wearer of equipment may wish to see that this notifies as early as possible, because it may be the part of talking with another person real-time (or closely real-time).
The another aspect of launching application program is that this launches the part of normally single affairs, such as " installation " application program.Once application program is through installing, then can there is the periodicity of application program and renewal infrequently that need to launch and install, but application program does not need to launch again substantially.Due to the size of application program, therefore on bluetooth connects, launch application program and can spend some times, thus (usually can take the form of the ongoing stream of little affairs with the transmitting of the data produced by the transducer on equipment, its generation can launch in little discrete packets constant of continuation mode but low-level data flow relatively) compare and introduce bluetooth and connect interrupted high risk (and increase application data will need the possibility of launching again, this consumes more electric power).If these little affairs are lost because bluetooth connects and interrupt, so due to interrupt launching the electric power wasted compared with the electric power wasted for larger transmittings such as such as application programs relatively little.
Application data discussed above and the difference between sensing data also can be relevant in the context of Figure 20 and 21, such as, when data self are through assessing to determine whether use BR/EDR or BLE to launch described data.

If select BR/EDR agreement in frame 2606, so described technology can proceed to frame 2608, and can use BR/EDR agreement transmitting data.If select BLE agreement in frame 2606, so described technology can proceed to frame 2610, and can use BLE agreement transmitting data between equipment and remote-control device.After data launch generation, the Bluetooth communication protocol selected in 2606 can be used further to excessive data, such as the second data, the 3rd data etc.Or, can make about whether utilizing BR/EDR agreement or BLE agreement to launch the independent decision-making of excessive data, that is, can for excessive data repeat block 2606.
Cell phone, smart phone and flat computer are all high mancarried device and therefore have the high likelihood carried by people, even if this people moves (situation of cell phone and smart phone is especially true).And if the bluetooth that biometric monitoring arrangement has to this little remote-control device connects, so highly likely remote-control device and biometric monitoring arrangement belong to same person.In some cases, there is the high probability that both biometric monitoring arrangement and remote-control device can be advanced together with the owner---in these cases biometric monitoring arrangement be connected with the bluetooth between remote-control device due to remote-control device to equipment continuous close close to and can not interrupt, and can bluetooth connect by maintenance complete rational expectation use BLE.

As in technology 1800, at certain point, may wish such as from equipment to remote-control device, from remote-control device to equipment or both, transmitting data between equipment and remote-control device, such as the first data.Can make in frame 2706 about whether utilizing BR/EDR agreement or BLE agreement to carry out the decision-making of transmitting data.Make in the scope of the blue-tooth device that the decision-making in frame 2706 can be installed at vehicle based on equipment.For example, many newer vehicles comprise can with the built-in speakers telephone system of the cellular telephone communication of people.If the blue-tooth device that equipment Inspection is installed to this vehicle in scope (or in some embodiments, in scope there is fully high signal strength signal intensity, the signal strength signal intensity such as matched with the signal strength signal intensity usually experienced when the inside of equipment at vehicle), so can make the determination using BLE agreement.If equipment does not detect the blue-tooth device that vehicle is installed, so equipment can use BR/EDR agreement.It should be noted that the blue-tooth device that vehicle is installed can be different from remote-control device.
If select BR/EDR agreement in frame 2706, so described technology can proceed to frame 2708, and can use BR/EDR agreement transmitting data.If select BLE agreement in frame 2706, so described technology can proceed to frame 2710, and can use BLE agreement transmitting data between equipment and remote-control device.After data launch generation, the Bluetooth communication protocol selected in 2706 can be used further to excessive data, such as the second data, the 3rd data etc.Or, can make about whether utilizing BR/EDR agreement or BLE agreement to launch the independent decision-making of excessive data, that is, can for excessive data repeat block 2706.
If in the scope of the blue-tooth device that biometric monitoring arrangement (or equipment) is installed at vehicle (or in scope and the signal strength signal intensity higher than a certain threshold value detected), the high likelihood of wearer in discussed vehicle of biometric monitoring arrangement so can be there is.If wearer is in this vehicle and exist and be connected with the bluetooth set up between remote-control device at biometric monitoring arrangement, so there is the increase possibility of remote-control device also in vehicle and therefore remote-control device will advance to the extraneous reduction possibility of biometric monitoring arrangement.In some embodiments, biometric monitoring arrangement also can determine how soon biometric monitoring arrangement advances, or whether the motion of biometric monitoring arrangement experience advances consistent with vehicle.For example, if the blue-tooth device that vehicle is installed detected and biometric monitoring arrangement detects that it is advanced with 50mph, so biometric monitoring arrangement can determine that biometric monitoring arrangement is in the vehicle that highway is advanced.Due to the limited range of bluetooth, existing bluetooth connection can not exist, unless it is to the remote-control device also in vehicle.Therefore, (except once vehicle slows to stopping, out can may being stayed in vehicle by remote-control device this wearer from vehicle simultaneously) is safe to suppose that connection can not be interrupted.

Can make in frame 2806 about whether utilizing BR/EDR agreement or BLE agreement to carry out the decision-making of transmitting data.Decision-making in frame 2806 can be made based on since bluetooth connects the time span of losing recently.For example, finally lose before if bluetooth is connected to more than 1 hour, so can suppose that bluetooth connects relatively stable and can select BLE, what just slow compared with BR/EDR data transmitting can not bring data transmitting to interrupt boosting chances.In other embodiments, keep recently when setting up and reach at least 5 minutes, 10 minutes, 15 minutes, 30 minutes, 60 minutes, 3 hours, 6 hours, 12 hours, 24 hours or other cycle, making the decision-making using BLE when bluetooth connects.
If select BR/EDR agreement in frame 2806, so described technology can proceed to frame 2808, and can use BR/EDR agreement transmitting data.If select BLE agreement in frame 2806, so described technology can proceed to frame 2810, and can use BLE agreement transmitting data between equipment and remote-control device.After data launch generation, the Bluetooth communication protocol selected in 2806 can be used further to excessive data, such as the second data, the 3rd data etc.Or, can make about whether utilizing BR/EDR agreement or BLE agreement to launch the independent decision-making of excessive data, that is, can for excessive data repeat block 2806.
Should be appreciated that, make to determine whether to use BR/EDR agreement or BLE agreement to be partial to single factor although each in above example concentrates on largely, this determines a bit also can based on the combination of this little factor, or the multilevel assessment of this little factor.For example, first equipment can be that application data is determined via BR/EDR agreement transmitting data based on data.But equipment can perform second based on batteries charge level subsequently and determine, if batteries charge level is extremely low, determine although BR/EDR so should be used to carry out first of transmitting data, second determines also to cause equipment utilization BLE agreement to carry out transmitting data.This determines also can simultaneously and non-coherently is made.In some embodiments, the determination of use BR/EDR based on other factors or BLE agreement can be surmounted based on the use BR/EDR of some factors or the determination of BLE agreement.For example, low batteries charge level can surpass other factors and cause use BLE agreement, and no matter other factors may indicate should use for which agreement.In this little embodiment, can construct and determine to make describedly to determine it is partly open-ended.For example, if batteries charge level is low, so this can force to use BLE agreement, and no matter what other factors may indicate.But if batteries charge level is higher, so the use of BR/EDR agreement is not compulsory, namely other factors can revise the determination about whether using BR/EDR agreement or BLE agreement.
Figure 29 describes to relate to and uses some criterions to determine whether to use bluetooth basic rate/enhancing data rate or the low-yield ability of bluetooth to carry out the flow chart of the case technology of transmitting data.Technology 2900 starts in frame 2902 (BLE and BR/EDR connects and may comparatively early set up, and as discussed relative to earlier figures, and the first data can be ready to launch between the equipment with BLE and BR/EDR ability and remote-control device).Decision-making about whether utilizing BLE agreement whether can be made lower than assign thresholds based on batteries charge level in frame 2902.If like this, so described technology can proceed to frame 2912 (optionally) and arrive frame 2914 subsequently.In frame 2912, can suspend or disconnect existing BR/EDR connection and occur (if needs) via BLE agreement with the communication of remote-control device to force.In frame 2914, can use BLE agreement between equipment and remote-control device, launch the first data.
If determine that batteries charge level is more than or equal to assign thresholds in frame 2902, so described technology can proceed to frame 2904, wherein can assess the first data to determine whether it is the part of application program or application program.If it is the part of application program or application program, so described technology can proceed to frame 2916, wherein can use BR/EDR agreement to launch the first data.If the first data are unascertained is the part of application program or application program, so described technology can proceed to frame 2906.In frame 2906, whether user or the wearer that can make equipment show as sleeping determination.If user or wearer show as sleeping, so described technology can proceed to frame 2912 or directly arrive frame 2914 when omitting frame 2912.
If do not determine that in frame 2906 user or wearer fall asleep, so technology 2900 can proceed to frame 2908, wherein can make the determination that the nearest loss connected since arbitrary bluetooth plays the time quantum of having pass by (to should be appreciated that, in this discussion selected about Bluetooth protocol and the context comparatively early discussed, " loss " is if refer to loss unintentionally---and disconnect BR/EDR wittingly and connect to force BLE to use, so this is not equal to bluetooth and connects " loss " event).In frame 2910, the time quantum having lost to have pass by can will be connected and Second Threshold compares since nearest bluetooth, if described time quantum exceedes Second Threshold, so described technology can proceed to frame 2912 (or when omitting frame 2912 directly to frame 2914) and can use BLE.If described time quantum does not exceed Second Threshold, so described technology can proceed to frame 2916, and can use BR/EDR.
Above example is only the example using multilevel method to determine to use which Bluetooth protocol based on various criterion or factor.Other embodiment can use various combination or the layout of the operation consistent with scope of the present invention.
Should also be clear that the technology of above-outlined can use together with wireless communication protocol in addition to bluetooth@, and the embodiment using this other wireless communication protocol a little also within the scope of the invention.Taking it by and large, this substitutes wireless communication protocol a bit can be characterised in that at least two agreements---one is higher bandwidth but draws more electric power (in bluetooth context, this is BR/EDR pattern), and one is lower bandwidth and draws less electric power (in bluetooth context, this is BLE pattern).Although be not strict necessary, two agreements can utilize common hardware (such as, antenna, receiver etc.) to save space, as the possible situation of bluetooth embodiment.
