`ABSTRACT
`
`For the purpose of realizing a display method for a portable
`electronic measuring device that allows the user to know his
`condition more easily and in greater detail by making it easy
`for him to read the display of measured results even if the
`display device is limited in size due to its portability. a bar
`graph is displayed in dot display area (134) of liquid crystal
`display device (13) of the portable pulse measuring device
`which extends up at each time interval according to the
`absolute value of the pulse rate after the measurement of
`time is started and until the pulse rate reaches a prescribed
`range. and after the pulse rate reaches the prescribed range,
`a bar graph is displayed that extends in the positive direction
`or the negative direction at each time interval according to
`the difference from the prescribed reference pulse rate.
`When temporal changes in the pitch during running are
`displayed in dot display area (134). they are displayed in a
`segmented graph.

`DISPLAY METHOD USED IN PORTABLE
`PULSE MEASURING DEVICE
`
`BACKGROUND OF THE INVENTION
`
`2
`method that continuously displays information on the
`selected mode as in the conventional device. battery life is
`that much shorter.
`H the temporal changes in the pulse rate are to be
`5 displayed in this type of portable pulse measuring device
`while running. normally data measured over a period of time
`exceeding 2 hours must be displayed on a display device of
`limited size. Therefore. measured results are displayed
`sequentially on a time base set with a sufficient margin.
`However. in this kind of display method. if used in a
`situation wherein the measurement time is short. then only
`a small amount of data will be displayed in a small area of
`the display device, thus making it difficult to use.
`
`10
`
`1. Field of the Invention
`The present invention relates generally to a display
`method for data. in a portable pulse measuring device that
`displays the pulse rate. among other data. In particular. the
`present invention is directed to displaying data on a wrist(cid:173)
`worn portable pulse measuring device.
`2. Description of the Related Art
`When a portable pulse measuring device capable of
`measuring pulse rate and other pulse information while
`being worn on a wrist has a built-in watch function as well, 15
`it can be used as a portable pulse measuring device that
`measures and displays both the pulse rate and lap time while
`running. In configuring this kind of portable pulse measur(cid:173)
`ing device. generally the current pulse rate and the time
`elapsed from the start time are displayed in segments on a 20
`liquid crystal display device.
`However. in this kind of portable pulse measuring device.
`since a marathon runner can only occasionally view the
`display when running in a marathon. it is difficult to see any
`trend and the runner cannot fully grasp his physical condi- 25
`tion because only the current pulse rate is displayed using
`segments.
`H measurement of the pulse rate is started without noting
`that warm-up or preparation is not complete in the internal
`circuitry when measuring the pulse rate while running using
`this type of portable pulse measuring device. a user may fail
`to measure the pulse rate. This kind of failure is critical in
`that measurement of the pulse rate during a marathon cannot
`be redone. Therefore. a method can be considered that
`displays the pulse rate from before starting as long as
`preparation of the electronic circuitry, etc., is complete.
`However, in this method. a user cannot confirm the
`reliability of measurement results before starting. That is,
`since the pulse rate is obtained from the frequency of the 40
`alternating current component of the pulse signal. even if the
`pulse detection unit is poorly attached, if there is an alter(cid:173)
`nating current component in the pulse signal. a value is
`obtained as the pulse rate. Therefore. the state of the pulse
`detection unit cannot be confirmed to be good or bad merely
`by the display of the pulse rate.
`In this type of portable pulse measuring device. the more
`functions that are provided, the more often mode selection
`will be performed, and each time information on the selected
`mode must be displayed in the display device. This mode so
`information is continually displayed in the display device in
`conventional electronic devices so that the user can confirm
`at any time which mode is set.
`However. in multifunction portable pulse measuring
`devices, even if there is much information that must be 55
`displayed, if a display area dedicated to displaying mode
`information is provided and the information is continually
`displayed there. then the area for displaying other informa(cid:173)
`tion becomes unavoidably small. Since the area for infor(cid:173)
`mation display must also be made small, it is difficult to read 60
`the displayed information. But if the display areas for both
`are expanded. a large display device would have to be used.
`thus detracting from the portability. Further, in a multifunc(cid:173)
`tion portable pulse measuring device. the more functions
`there are. the more power that is consumed as compared to 65
`a regular watch. but the power supply cannot be made larger
`because portability must be maintained. Therefore. in a
`
`OBJECTS OF THE INVENI10N
`
`Therefore. it is an object of the present invention to
`overcome the aforementioned problems.
`It is an additional object of the present invention to
`provide a portable electronic measuring device that allows
`the user to know his condition more easily and in greater
`detail by making it easy for him to read the display of
`measured results even if the display device is limited in size
`due to its portability.
`It is a further object of the present invention to provide a
`portable pulse measuring device that makes it possible to
`confirm whether or not measurement preparation. i.e ..
`attached condition of the pulse detection unit. is sufficient
`before starting measurement of the pulse rate.
`It is also an object of the present invention to provide a
`portable pulse measuring device that displays information so
`that it is easy to read even without making the display device
`larger and that makes it possible to reduce the power
`consumed in displaying mode information.
`It is still an object of the present invention to provide a
`portable pulse measuring device capable of correctly dis(cid:173)
`playing the temporal progress of measurement results
`regardless of the length of the measurement time and
`without having to make the display device larger.
`
`SUMMARY OF THE INVENI10N
`
`30
`
`35
`
`To achieve the above. this invention implements the
`display method in a portable pulse measuring device as
`45 described below.
`According to a first aspect of the present invention. to
`allow the user to easily know his condition in detail by
`facilitating reading of displayed measured results the present
`invention accomplishes this by switching the graphic dis(cid:173)
`play mode between a first measurement period until the
`measured pulse rate reaches a prescribed value after graphic
`display of the pulse rate has started and a second measure(cid:173)
`ment period after the pulse rate has reached the prescribed
`value in a portable pulse measuring device capable of
`measuring the pulse rate while being worn as well as
`graphically displaying temporal changes in the measured
`pulse rate on the display device.
`When the portable pulse measuring device of this inven(cid:173)
`tion is used to monitor a runner's pulse rate during a
`marathon or while jogging. for example. the runner can
`easily know at what level his pulse rate is according to the
`display mode by merely glancing at the display device
`occasionally. Moreover. since the temporal changes in the
`pulse rate are displayed graphically, the runner can know his
`condition in detail. Further. even though the pulse rate will
`change quickly immediately after the start of a marathon. the
`display mode will still change automatically according to the
`
`23 of 38
`
`

`
`5.795.301
`
`3
`level. and therefore an easy-to-read display can be per(cid:173)
`formed according to the level of the pulse rate in a display
`area of limited size.
`For example. a bar graph is displayed in a first measure(cid:173)
`ment period that extends according to the absolute value of 5
`the measured pulse rate. and in a second measurement
`period. a bar graph that extends in the positive direction or
`the negative direction is displayed at each time interval
`according to the difference between the measured pulse rate
`and the prescribed reference pulse rate. By means of this 10
`configuration. even though the display area may be small. a
`detailed comparison with the pulse rate (physical condition)
`during training can be easily performed.
`In accordance with a second aspect of the present
`invention, even after performing an external operation that
`stops the measurement of time that was performed together
`with the measurement of the pulse rate. it is desirable to
`graphically display temporal changes in the measured pulse
`in a mode different from the second measurement period
`while continuing to measure the pulse rate for a prescribed
`period. By means of this configuration. recovery of the pulse
`rate during marathon training. etc.. can be known. In this
`case. as well. display of the recovery and display during time
`measurement use different display modes. and therefore it is
`easy to distinguish the pulse rate of which period is being 25
`displayed.
`In accordance with a third aspect of the present invention.
`it is desirable to display the pulse rate immediately after or
`immediately before the external operation that stops the
`measurement of time is performed at the same time the
`current pulse rate is displayed for the prescribed time period.
`In this way. the pulse rate immediately after or immediately
`before the measurement of time is stopped can be easily
`compared to the subsequent pulse rate. thus making it easy
`to confirm recovery of the pulse rate.
`In accordance with a fourth aspect of the present
`invention. the portable pulse measuring device may also be
`configured such that the contents of the graphic display can
`be switched between display of the temporal change in the
`pulse rate and display of the temporal change in the pitch
`sought based on the measured results of the acceleration
`sensor. In this case. it is desirable to make the graphic
`display mode for temporal changes in the pulse rate in the
`first and second measurement periods different from the
`graphic display mode for temporal changes in the pitch. For
`example, temporal changes in the pitch can be displayed in
`a segmented graph plotted at each time period corresponding
`to the absolute value of the pitch. By means of this
`configuration. the runner can easily distinguish what is
`currently being displayed by merely observing the display
`mode. Also, the runner can easily determine his physical
`condition in detail from the temporal changes in the pitch.
`Next. for the purpose of making it possible to reliably
`confirm whether or not measurement preparation. i.e .•
`attached condition of the pulse detection unit. is sufficient
`before starting measurement of the pulse rate. it is desirable
`that the pulse signal be graphically displayed in the display
`device from when the mode is switched to the pulse rate
`measurement mode based on an external operation until an
`external operation is performed that starts time measurement
`and that the pulse rate be graphically displayed in the display
`device after an external operation is performed that starts
`time measurement.
`By means of this configuration. not only is it possible to
`reliably confirm that preparation for measurement of the
`pulse rate is complete by whether or not the pulse signal is
`
`4
`being graphically displayed. it is possible to specifically
`judge from the waveform or level of the pulse signal whether
`or not the pulse detection unit is properly attached before
`starting measurement of the pulse rate. It is also possible to
`adjust the attached condition of the pulse detection unit
`while confirming the waveform or level. Further. this func-
`tion can also be used to inspect for good and defective
`products in the production of pulse measuring devices.
`Moreover. since the waveform is displayed graphically. it is
`possible to confirm the stability of the time base.
`In accordance with a fifth embodiment of the present
`invention. from when the mode is switched to the pulse rate
`measurement mode based on an external operation until
`processing that seeks the pulse rate becomes possible. it is
`15 desirable that information indicating same be displayed in
`the display device and that the pulse signal be displayed in
`the display device from the time processing that seeks the
`pulse rate becomes possible until an external operation that
`starts time measurement is performed. By means of this
`20 configuration. it is possible to reliably confirm that prepa(cid:173)
`ration for pulse rate measurement is complete by merely
`seeing that the pulse signal is being graphically displayed.
`When the pulse rate is graphically displayed in this
`invention. it is desirable that the pulse signal be amplified
`until it is of a prescribed amplitude and that the amplitude
`level be displayed in the display device. By means of this
`configuration, the attached condition of the pulse detection
`unit can be accurately confirmed by considering the ampli(cid:173)
`fication level together with the original waveform of the
`30 pulse signal.
`When graphically displaying the pulse wave in this
`invention. it is desirable that display be switched to newly
`measured pulse signals during normal power load but that
`35 during heavy power loads, such as when the backlight is on
`in the display device or when the alarm sounds. the display
`be fixed at the pulse signal that was being displayed until the
`heavy load condition is terminated. By means of this
`configuration, even if the pulse signal cannot be accurately
`detected during a heavy power load, the currently displayed
`waveform is graphically displayed in a fixed state instead of
`the newly measured pulse signal. and therefore an irregular
`waveform need not be displayed.
`In accordance with a sixth embodiment of the present
`45 invention. for the purpose of displaying easy-to-read infor(cid:173)
`mation without having to make the display device larger and
`to reduce the power consumption required to display mode
`information. it is desirable that information on the selected
`mode be displayed in the display device when the mode is
`50 selected by an external operation and that display of the
`mode information automatically turns off after a prescribed
`time has elapsed.
`By means of this configuration. the information display
`eventually turns off, and therefore it is possible to display
`55 information that considers only ease of reading without
`having to provide a large dedicated display area for infor(cid:173)
`mation display. Also. when the display is left off after
`information display has been performed. the fact that the
`information display itself is off means that a specific mode
`60 has been selected. Also. since display is performed only for
`the minimum time required for the user to confirm the mode.
`power is conserved. For this reason. the battery life can be
`extended in a multifunction portable pulse measuring device
`that can only hold small batteries from the standpoint of
`65 portability.
`In accordance with a seventh embodiment of the present
`invention. it is desirable that the display device comprises a
`

`segment display area for displaying time information and a
`dot display area for graphically displaying various types of
`information, that information on the selected mode be dis(cid:173)
`played in the dot display area and that display of the mode
`information automatically turn off after a prescribed time 5
`has elapsed. By means of this configuration, information is
`displayed in the dot display area which is capable of
`displaying much information, and therefore the information
`is easy to read. In this case, as welL information display
`automatically turns off. and therefore power is conserved
`even if the power consumption of the dot display area is
`large.
`Of the modes wherein display of information on the
`selected mode automatically turns off in this invention, after
`display of information on the selected mode is performed 15
`while the time mode is selected, it is desirable that display
`of information in the display area remain off. Since the
`frequency of returning to the time mode is high in a portable
`pulse measuring device, power conservation can be maxi(cid:173)
`mized when returning to this time mode if the mode infor- 20
`mation method of this invention is utilized.
`Next. in this invention. for the pwpose of accurately
`displaying temporal transitions in the pulse rate regardless of
`the length of the measurement time and without making the
`display device larger, it is desirable that the portable pulse 25
`measuring device comprise a plurality of data compression
`means capable of data compression with respect to time of
`ratio or rank of two or better of the measurement results of
`the pulse rate measured at each fixed time. A plurality of
`compressed data memory means stores the compressed data 30
`obtained by the data compression means. A data compres(cid:173)
`sion control means that controls the data compression means
`such that they recompress data stored in the compressed data
`memory means at a
