Fig. 3 is worn on when (indicating with Reference numeral 10 usually among the figure) on the wrist when device, and the wrist strap in Fig. 2 is the cross-sectional view strength of this portable unit longitudinally.Different with the embodiment of Fig. 1, when wearing, this portable unit for good and all contacts with the organic organization of user with its optical device 5.Light by light source 51 emissions penetrates the enough degree of depth of organic organization, thereby modulates by the blood perfusion of irradiated organic organization.After the photoreceptors 52 to 54 of optical device is reacted, just can detect the emission of modulated light.
Fig. 4 is a block diagram, the main building block of the portable unit in showing according to one embodiment of present invention.As shown in the figure, this portable unit comprises light source 61 (for example light emitting diode (LED) or any other suitable equipment), and it is connected to control circuit 71, and its operation is controlled by CPU 70, for example microprocessor or microcontroller.This central location 70 also is connected in display device 73 (simulation and/or numeric type), memory element 74 (random-access memory (ram)s, read only memory (ROM), electronics erasable programmable read-only memory (EEPROM), flash memory (FLASH) or analog) and clock system 75, this clock system is determined the suitable function timing of central location 70 and peripheral assembly thereof.This clock system 75 also can be realized the time clock feature of traditional clock and watch.
The method that nobody can measure being used to here physiological parameter further enlarges, and its reason is that this problem does not directly relate to theme of the present invention.Moreover, exist the different solutions of carrying out this measurement.Just a kind of especially effectively solution that is used to measure heart rate has been done detailed description in the document EP of mentioning in front 1297784, this piece document is incorporated herein by reference.
In the embodiment of Fig. 4, in order and/or to accept data by its optical device transmission, this portable unit also comprises, on the one hand, modulation element 81, it is connected between the control circuit 71 and central location 70 of light source, and on the other hand, restitution element 82, it is connected between the amplifier element 63 and central location 70 that is connected with photoreceptors 62.
The purpose that is appreciated that modulation element 81 is to control control circuit 71, so that produce synthetic optical signalling by the light source 61 that connects.Equally, be appreciated that the purpose of restitution element 82 is on the contrary, the modulated light signal that is obtained by the photoreceptors 62 that connects is decoded.Any modulation type can both be used for the transmission and the reception of data.Can be traditional amplitude, phase place, frequency or code modulated.Whether in addition, also adopt transmission and reception that special modulation is used for data, be radiatively to inject or send out outward so that clearly identify.Under any situation, the modulation of optical signalling all is based on the data that will transmit.
In Fig. 4, it should be noted that this portable unit can comprise a more than light source and/or a more than photoreceptors.Especially, shown in the dotted line among Fig. 4, second photoreceptors 64 and connected amplifier element 65 all are connected on the detector 72, and the latter needn't be connected with decode element 82.Equally, the 3rd photoreceptors 66 and connected amplifier element 67 all are connected on the decode element 82, rather than are connected on the detector 72.The 3rd photoreceptors does not participate in the detection of the physiological parameter of expectation then, only is used for data and receives.
Usually, within the scope of the invention, it should be noted that, also be fine if at least one light source of the measurement that is generally used for the expected physiological parameter of optical device or photoreceptors also are respectively applied for the transmission or the reception of data.In fact, people more wish only to reduce the function of producing originally living and simplified structure by using a light source or photoreceptors to realize, thus the acquisition advantage.It is also to be noted that, preferred use special photoreceptors to measure physiological parameter separately, and other photoreceptors is used to receive data, above-mentionedly be proved the restriction that is subjected to sensitivity.
Within the scope of the invention, it also is favourable that the device with detecting element is provided, and this checkout gear is used for automatically, optionally starting the physiological parameter measurement function of optical device, perhaps data emission/receiving function.
By first embodiment, this portable unit can comprise first detecting element, when the latter is an optical device when contacting with organic organization, is used for automatically starting the physiological parameter measurement function of optical device.One preferably solution can comprise based on by the detected photoemissive intensity of at least one photoreceptors, come detection optical equipment whether to contact with organic organization.
In a second embodiment, this portable unit also can comprise two detecting elements, is used for automatically starting the transmission and/or the receiving function of the data of optical device when this portable unit sends data.One preferably solution also comprise based on by the detected photoemissive intensity of at least one photoreceptors, detect data and whether send to portable unit.
Refer again to Fig. 4, it also is favourable that portable unit also has element 90, and this element is used for the light emission intensity level by one or more photoreceptors Detection and Extraction.In fact, it is contemplated that at portable unit when measurement pattern is worked, optical signalling that can difference is sent by external unit from optical signalling or the signal that is particularly extracted by same photoreceptors, the optical signal intensity that is produced by external unit can be adjusted to than the higher intensity of average level of measuring the optical signalling during the physiological parameter.
Fig. 5 is with illustrate this probability of chart by changing along with the time, increased a line of representing the optics heart rate measurement and representative line by the modulation signal of external unit transmission in this time block diagram, the corresponding strength of selecting these signals is a different value.By strengthening detection threshold Vth as shown in the figure, therefore just this signal of two types can be differentiated, and portable unit switches to appropriate mode.
From this principle, just can realize optionally start-up detector 72 or decoder 82 by element 90.Decoder 82 also can be used to decode and detect the predetermined optics control signal that is transmitted by external unit.Therefore, the first optics control signal of encoding according to the known array of portable unit can transmit by external unit, thereby portable unit is given a warning: data (for example structured data) will transmit thereto.Similarly, the second optics control signal of encoding according to another known codes sequence of portable unit is sent to external unit, thereby the order portable unit sends data (physiological parameter that for example is stored in the measurement in the memory element 74 as time passes and the data that change).
If be not enough to and distinguish between the optical signalling based on the signal intensity of gathering merely, element 90 can optionally be used for the particular modulation characteristic according to the optical signalling of external unit transmission, thereby signal is distinguished, for example according to the frequency analysis of the signal that receives.Also can expect adopting other similar elements.
Be appreciated that at last for a person skilled in the art, to embodiment of the present invention to make amendment and/or improve be conspicuous, and can not exceed the scope of invention that limits by incidental claims.Especially, the present invention not only uses with the form of wrist-watch, and can use with the form of other any portable units, and no matter whether it is worn on the wrist.
