JP 2005-324709 A

Incidentally, in recent years, an increasing number of bicycle display devices are equipped with a GPS display device and a large color display screen with map data. This makes it possible for the user to view the current position linked to the map. However, with such a large display screen, the power consumption increases accordingly. Therefore, there is a demand for a technology that can suppress power consumption while having a large display screen with large power consumption. As a technique for suppressing power consumption, for example, also in Patent Document 1, when the battery is exhausted, the main display unit 10A is not displayed and only the sub display unit 10B is displayed to suppress power consumption. The technique of doing is disclosed. However, the technique of Patent Document 1 is merely an emergency means for not stopping the display function when the battery is exhausted, and does not suppress power consumption in a normal display mode. Moreover, traveling information that cannot be displayed by such means is generated.
Therefore, even if the battery (concept including a rechargeable secondary battery and a primary battery such as a dry battery) has a sufficient amount of electricity, it suppresses power consumption as much as possible, and it is large in size that consumes a large amount of power. There has been a demand for a bicycle display device that can display all the travel information that can be displayed including a display mode in which map data is developed on a display screen.
The present invention has been made to solve the above problems, and its purpose is to suppress the power consumption of the display screen while always having a display screen with a large power consumption, and always display necessary traveling information. It is to provide a bicycle display device and a bicycle display device program.

In order to achieve the above object, according to the first aspect of the present invention, there is provided a display device that displays information that changes with traveling (hereinafter referred to as traveling information) during traveling by a bicycle so that the user can see it. A first display screen, a second display screen that consumes relatively less power than the first display screen, and a control means for performing display control on the first and second display screens, The control means displays, on the second display screen, second traveling information that changes during traveling and that can be grasped by the user while traveling, and the second traveling information and In comparison, during the traveling, control is performed to display the first traveling information, which is relatively difficult for the user to grasp the traveling information displayed on the display screen, on the first display screen. Always displays the second driving information That one, and its gist to carry out control to power saving mode by said first display screen a predetermined condition.
With such a configuration, for example, the second display information is always displayed on the second display screen during the travel, while the first display screen displaying the first travel information is under a predetermined condition. The power consumption suppression mode is set. Accordingly, for example, the second traveling information is always displayed on the second display screen, and the first display screen side is set to the power consumption suppression mode, so that the second display screen cannot be seen as clearly as the second display screen, for example. Display control in such a low luminance or off state can be performed, and the power consumption of the first display screen, which consumes a large amount of power, can be suppressed. In other words, in the normal driving state, the second display screen, which originally consumes less power than the first display screen, is mainly viewed, and the display of driving information with large power consumption is secured on the first display screen. The idea is to reduce power consumption.

Here, as the second traveling information, the traveling information changes during traveling and can be grasped by the user while changing, and is displayed on the display screen during traveling as compared with the second traveling information. What is relatively difficult for the user to grasp the travel information is the first travel information.
The travel information may be information on the state of the bicycle itself, the state of the environment around the bicycle, the state of the driver driving the bicycle, and the like. Specifically, for example, travel speed, current position, average speed, distance to the destination, lap measurement to the destination, direction of the destination, crank rotation speed (cadence), heart rate state during travel (heart rate) , Altitude, barometric pressure, bearing, road gradient, time, date, etc. Among these, what can become the second traveling information is “information that changes during traveling and can be grasped by the user while changing”. On the other hand, the first travel information is travel information that is relatively difficult for the user to grasp the travel information displayed on the display screen during travel compared to the second travel information. For example, the second driving information is changed during driving, and the information that can be displayed by a numerical value or a graph is assumed to be grasped by the user while changing, while the first driving information is changed to the second driving information. Compared to the map, it is assumed that the travel information displayed on the display screen during travel is a map that is relatively difficult for the user to grasp the travel information. As in this example, the first traveling information may be information that needs to read the entire arrangement relationship, while the second traveling information may be information that does not need to read the entire arrangement relationship. The first traveling information may be information that needs to be interpreted, while the second traveling information may be information that does not require interpretation.
The control means may comprise a control unit such as a single microcomputer that controls both the first display screen and the second display screen, and the first microcomputer such as the first microcomputer that controls the first display screen. You may make it comprise from one control part and several control parts, such as 2nd control parts, such as a 2nd microcomputer which controls a 2nd display screen.
The bicycle display device can be attached integrally with the bicycle or indirectly (secondarily) by attachment means such as an adapter.

In the invention according to claim 2, in addition to the invention according to claim 1, the second travel information is travel information based on a signal from a detection means for detecting the movable state of the movable part of the bicycle. The gist of the first travel information is travel information based on a signal from a detection means for detecting a state where the movable portion of the bicycle is not in a movable state.
This shows an example in which the difference between the first traveling information and the second traveling information is further embodied from the first aspect. Specifically, the “detection means for detecting the movable state of the movable part of the bicycle” specifically includes, for example, a wheel rotation sensor (wheel rotation number detection means) for detecting the rotation speed of the wheel and a crank rotation sensor (for detecting the rotation speed of the crank). Crank rotation speed calculation means). Examples of information obtained by these detection means include travel speed and crank rotation speed (cadence). Further, for example, an average speed obtained secondarily based on these pieces of information, a lap measurement to the destination, a distance to the destination, and the like can be mentioned. As described above, the “running information based on the signal from the detection unit” may be, for example, information itself included in the signal from the detection unit, or information derived using information included in the signal from the detection unit. It is good. For example, the detection unit may output a plurality of signals, and the traveling information may be information derived based on the plurality of signals.

In the invention according to claim 3, in addition to the invention according to claim 1 or 2, the second traveling information is information updated more frequently during traveling than the first traveling information. This is the gist.
This shows an example in which the difference between the first and second traveling information is further embodied from the first or second aspect. The frequently updated information is information whose value changes every moment and is information that the user always wants to visually check. Therefore, this information is displayed on the second display screen which is a constant display screen. For example, the traveling speed obtained from the information of the wheel rotation sensor is frequently updated because the wheel rotates several times per second. In the case of map information, the map is displayed when a certain area is displayed on the screen. Since the information does not change abruptly compared with the traveling speed obtained from the information of the wheel rotation sensor, it is not frequently updated. The information of the crank rotation sensor is also updated more frequently than the map information.

In the invention according to claim 4, in addition to the invention according to any one of claims 1 to 3, the second traveling information is one or a plurality of information selected by a user from a plurality of traveling information. Is the gist.
As a result, it is possible to display any travel information that the user wants to see at all times on the second display screen, and to make travel information that always displays only the travel information selected by the user according to the purpose of the user. As a result, the range of traveling information to be displayed at all times is widened. For example, the selection by the user may be configured such that the input means is also received and input is selected, or the information for specifying the travel information selected is stored in the storage means, and the selection is made according to this information. You may comprise.
According to a fifth aspect of the invention, in addition to the fourth aspect of the invention, the user selects the second traveling information based on the display of the input screen displayed on the first display screen. This is the gist.
Although it is easier to input an input screen having a certain area, power consumption tends to increase as the screen becomes larger. Therefore, the second display screen that is always displayed does not set the input screen in order to suppress power consumption, and can be set to the power consumption suppression mode from the first display screen side to the second display screen side. It is assumed that the travel information 2 is set. Thus, even if the input screen of the first display screen is enlarged, the power consumption suppression mode can be set, so that power consumption is suppressed. Further, when the input screen is displayed on the first display screen in order to execute arbitrary selection of the second traveling information, the power consumption suppression mode is not set.
In the invention according to claim 6, in addition to the invention according to any one of claims 1 to 5, the same traveling information as the selected second traveling information is not displayed on the first display screen. Is the gist.
That is, the second traveling information is displayed only on the second display screen that is always displayed, and is not visible from the first display screen. As a result, it is possible to reduce the influence on the display space of the travel information other than the second travel information due to the same travel information being displayed twice in the bicycle display device which originally has a small display screen and has a small margin. it can. It also has the meaning of simply eliminating the need for double display.

The gist of the invention according to claim 7 is that, in addition to the invention according to any one of claims 1 to 6, the second traveling information is numerical information that changes over time.
This is because the travel information that can be displayed with such numerical values is representative information that can be grasped instantaneously by the user, and is appropriate as the second travel information. Examples of travel information that can be expressed as numerical information include travel speed, average speed, distance to the destination, lap measurement to the destination, crank rotation speed (cadence), heart rate during travel (heart rate), altitude , Pressure, direction, road gradient, time, date, etc.
In the invention according to claim 8, in addition to the invention according to any one of claims 1 to 7, the control means turns off the first display screen in the power consumption suppression mode. The gist.
This is a specific example of the power consumption suppression mode on the first display screen. This is because power consumption can be significantly suppressed by turning off the light at all times.
In the invention according to claim 9, in addition to the invention according to any one of claims 1 to 7, the control means attenuates the luminance of the first display screen in the power consumption suppression mode. This is the gist.
This is a specific example of the power consumption suppression mode on the first display screen. This is because, although the display state in which the first traveling information is attenuated is always attenuated by reducing the luminance, it can be visually observed and the power consumption can be suppressed.

In the invention according to claim 10, in addition to the invention according to any one of claims 1 to 9, the control means cancels the power consumption suppression mode of the first display screen by an input operation by the input means. In addition, the gist is to shift to the power consumption suppression mode again after a predetermined time.
This is a condition for canceling the power consumption suppression mode of the first display screen that is always in the power consumption suppression mode and setting the same normal display mode as the second display screen. Although the normal display mode can be set by operating the input means, the power consumption can be suppressed by shifting to the power consumption suppression mode again after a predetermined time has elapsed. The predetermined time can be changed and set.
Here, as the “input unit”, when the first display screen also serves as a touch panel, the first display screen itself is used as the input unit. In addition, an input button switch or the like provided in the bicycle display device is assumed.

The invention according to claim 11 is characterized in that, in addition to the invention according to any one of claims 1 to 10, the first display screen is a screen larger than the second display screen.
In such a configuration, since the first display screen that is in the power consumption suppression mode is larger than the second display screen, a greater power consumption suppression effect can be expected.
In the invention according to claim 12, in addition to the invention according to any one of claims 1 to 10, the first display screen is larger than the second display screen, and the first traveling The gist is that the information is displayed in a larger area than the second traveling information.
In such a configuration, since the first display screen that is in the power consumption suppression mode is larger than the second display screen, a greater power consumption suppression effect can be expected. In addition, power consumption can be suppressed by displaying information that is preferable to be displayed in a large area on the first display screen side as first traveling information.

According to a thirteenth aspect of the present invention, in addition to the invention according to any one of the first to twelfth aspects, the second display screen is arranged facing a driver's line of sight in a state where the second display screen is attached to a handlebar or a stem. In addition, the gist is that the first display screen is arranged in a different direction from the second display screen.
By adopting such a configuration, it is possible to view the running information by simply moving the line of sight to the second display screen while keeping the running posture while the user is running. It is easy to check the travel information of 2. On the other hand, by not arranging the first display screen on which the first traveling information, which is not frequently viewed as often as the second traveling information, is displayed in the direction of the user's line of sight, a screen that is not often viewed is easy to see. Thus, the second display screen is not disturbed by visual observation. The direction of the first display screen is preferably a direction displaced upward with respect to the direction of the second display screen.

The gist of the invention described in claim 14 is that, in addition to the invention described in any of claims 1 to 13, the first display screen displays map information as travel information.
This is because map information is often displayed in a large display area and color, and thus consumes a large amount of power and is preferably a target of a power consumption suppression mode.

According to a fifteenth aspect of the invention, in addition to the invention according to any one of the first to fourteenth aspects, the first display screen is composed of a display composed of a dot matrix type color liquid crystal panel. The gist.
If the first display screen is composed of such a display of a dot matrix type color liquid crystal panel, the power consumption is large, and because it is such a display, it is preferable to be the target of the power consumption suppression mode. is there.
The gist of the invention described in claim 16 is that, in addition to the invention described in any one of claims 1 to 14, the second display screen is constituted by a display composed of a monochrome liquid crystal panel.
If the second display screen is composed of such a display, the power consumption is small, and therefore it is a preferable device when displaying in a normal manner at all times.
The gist of the invention described in claim 17 is that in addition to the invention described in claim 16, the display of the second display screen is a segment display.
This is because the segment display consumes less power than the dot display and is preferable as the second display screen.
The gist of the invention described in claim 18 is that, in addition to the invention described in any one of claims 1 to 17, a secondary battery is used as a power source.
This is because it is necessary to suppress power consumption because it is a bicycle display device that consumes enough power to use a secondary battery as a power source.
The gist of the invention described in claim 19 is a program for causing a computer to function as the control means in the bicycle display device according to any one of claims 1 to 18.

  According to the present invention, even when the display screen has a large power consumption, the power consumption of the display screen can be suppressed, and the necessary traveling information can be always displayed while suppressing the power consumption. Is possible.

It is attached to the position which can detect The wheel rotation sensor 25 detects the magnetic field lines of the magnet 29 attached to the wheel 27 once for each rotation of the wheel. The crank rotation sensor 26 detects the magnetic lines of force of the magnet 31 attached to the pedal 30 once for each rotation of the pedal.

Next, the electrical configuration inside the casing 11 of the cycle computer 10 will be described based on the block diagram of FIG. In addition, about the structure which is not directly related to this invention, it abbreviate | omits.
A position detector 33, a memory card reader 34, a database 35, a sensor signal receiver 36, first and second display screens 17 and 18, the power switch 24, etc. are connected to the controller MC as a control means. .
The controller MC is composed of a known CPU, a memory such as a ROM and a RAM, a microcomputer having a timer and the like. In the ROM in the controller MC, the first traveling speed calculation program for obtaining the traveling speed based on the output from the wheel rotation sensor 25 received by the sensor signal receiver 36 is received by the sensor signal receiver 36. Crank rotation speed calculation program for obtaining the crank rotation speed converted per minute based on the output from the crank rotation sensor 26, the calculated traveling speed, the crank rotation speed, the average speed, the lap measurement to the destination, etc. Is stored as a numerical value display program or the like on the first or second display screen 17 or 18. The controller MC also changes the mode of the first display screen 17 from the normal visible display mode to the power consumption suppression mode, or the first or second display screens 17 and 18. A travel information setting program for setting travel information to be displayed on is stored.
Further, as a program related to the position detector 33, a GPS information processing program for processing GPS information received by the GPS receiver 37 of the position detector 33, and map data is received by the GPS receiver 37 of the calling position detector 33. A map display program to be displayed on the first display screen 17 in association with the received position data, the position data received by the GPS receiver 37 of the position detector 33 and the travel speed for obtaining the traveling speed from the moving distance per unit time. 2, and various programs such as a history storage program for storing a travel history (log data) received by the GPS receiver 37 in an SD card are stored.
Further, the calculated values calculated by the above calculation programs and the position information detected by the position detector 33 are temporarily stored in the RAM.

The position detector 33 as a current position acquisition means, a speed acquisition means, and a current time acquisition means includes a GPS receiver 37 as a known time acquisition means for acquiring GPS information as the core of the configuration. Speed calculation is performed based on the positional information and the movement distance acquired based on the information. The detected position information is the latitude, longitude and altitude of the vehicle. As the travel speed acquisition source, it is possible to select either the case based on the GPS receiver 37 or the case based on the wheel rotation sensor 25.
The memory card reader 34 reads data on the SD card or updates data on the SD card.
The database 35 is a nonvolatile memory (for example, EEPROM) in the controller MC or externally attached to the controller MC. In the present embodiment, object data to be displayed on the first and second display screens 17 and 18 in the database 35, master image data, and various fonts to be displayed on the first and second display screens 17 and 18 in the database 35. Data etc. are stored. These data may be stored in the ROM.
The sensor signal receiver 36 is a receiving chip comprising an integrated element group, and receives detection data transmitted from the sensor signal transmitters 38 and 39 on the wheel rotation sensor 25 and crank rotation sensor 26 side. The sensor signal receiver 36 and the transmitters 38 and 39 use ANT plus (+) for short-range wireless communication as a wireless communication protocol, but other communication protocols such as Bluetooth may be used as a communication protocol.
In addition, the controller MC detects a contact state with the first display screen 17 at a timing of 100 msec, and performs processing according to a command by GUI input.

An example of a display routine executed by the controller MC in the electrical configuration as described above will be described based on a flowchart.
First, the display main routine will be described with reference to FIG.
When the controller MC detects the power ON state in step S1, the controller MC starts the display operation on the first and second display screens 17 and 18 in step S2. Specifically, the first display screen 17 displays a master image (display areas 41 to 43 and icons 44 to 47 below) as shown in FIG. On the second display screen 18, the master image (character display area 50 shown below) as shown in FIG.
In FIG. 7, the current position P is plotted and displayed on the map display area 41 where the map is developed based on the movement distance information from the GPS receiver 37. A distance display area 42 and a speed display area 43 are displayed at the upper position of the map display area 41, and the travel distance and speed from the reset state are displayed, respectively. At the lower position of the map display area 41, a lap setting icon 44, which is a button icon for setting a lap, an erasing icon 45, which is a button icon for erasing the record of elapsed time and travel distance, elapsed time and travel A recording setting icon 46, which is a button icon for starting and stopping distance recording, is displayed. A map scale display area 47 that displays a map scale and a current location address display area 48 that displays a current location address are displayed below the icons 44 to 46.
In FIG. 8, a character display area 50 is displayed above the 7-segment display unit 49. Depending on the setting, the text display area 49 displays the content of the travel information of “speed”, “travel distance”, or “cadence”, and the 7-segment display portion 49 is a numerical value corresponding to the travel information displayed in the text display area 50. Is displayed.
In step S3, the controller MC executes a power suppression display subroutine. When the controller MC detects a power-off state in step S4, the controller MC stores the past travel distance and ends the main routine.

Next, the power suppression display subroutine will be described with reference to FIG. The power suppression display subroutine explains the processing of the controller MC for causing the first display screen 17 to take either the normal display mode in which traveling information can be visually observed or the power consumption suppression mode turned off. In this embodiment, the controller MC executes this subroutine at a timing of 100 msec after the process of step S2 of the main routine until the power is turned off in step S4.
In step S11, the controller MC determines whether or not the first display screen 17 has been touched. If the controller MC determines that the touch has been made, the process proceeds to step S12. On the other hand, if it is determined that there is no touch, the process proceeds to step S13. Here, by touching the first display screen 17, the first display screen 17 in the unlit state (power consumption suppression mode) is turned on so that normal driving data can be visually observed (normal display mode). The user touches the first display screen 17 as an input operation to the mode switching input means.
First, in step S12, it is determined whether or not the first display screen 17 is turned off. When the first display screen 17 is turned off, that is, in the power consumption suppression mode, the first display screen 17 is turned on in step S14. Set to normal display mode. This means that the first display screen 17 is returned to the lit state when it is currently turned off. Next, in step S15, the controller MC determines whether 30 seconds have elapsed since the touch. If it is determined that 30 seconds have elapsed, the flag is set to “1” in step S16, and a standby state is set until the next subroutine is executed. In this standby state, this routine is terminated in the normal display mode. On the other hand, if 30 seconds has not elapsed in step S15, the process proceeds to step S17, and it is determined whether or not the touch is performed again. If there is no touch, the process returns to step S15, and if there is a touch, the process proceeds to step S12. The processing in step S17 is intended for the case where the first display screen 17 is touched or continuously touched many times.

On the other hand, when the process proceeds to step S13, that is, when there is no touch on the first display screen 17, it is determined in step S18 whether 30 seconds have passed since the power is turned on or whether the flag is “1”. If not, the process proceeds to step S11. This is a process in which lighting is continued when 30 seconds have not yet elapsed since the first display screen 17 is turned on. On the other hand, if 30 seconds have elapsed since the power was turned on in step S18 or the flag is “1”, the light is turned off in step S19. In other words, it is a process for determining that 30 seconds have elapsed since the last touch of the first display screen 17 after the power is turned on or setting the first display screen 17 to the power consumption suppression mode. Next, when the flag is “1” in step S19, the flag is set to 0, and a standby state is set until the next subroutine is executed. In this standby state, this routine ends in the power consumption suppression mode.

Next, an input operation for setting traveling information to be always displayed on the second display screen 18 in a power-on state will be described.
a) When the access from the first display screen 17 of the user (for example, short two touches are detected) is detected, the controller MC first displays a screen 51a capable of GUI input as shown in FIG. 9A. It is displayed on the screen 17.
b) When it is detected that the user has touched “SETTING” on the screen 51a, the controller MC causes the first display screen 17 to display the screen 51b (FIG. 9B) which is a lower layer of the screen 51a.
c) Next, when it is detected that the user touches “always display information” on the screen 51b, the controller MC displays the screen 51c (FIG. 9C), which is a lower layer of the screen 51b, as the first display screen 17. To display.
c) The screen 51c is a screen that prompts the user to select one of “speed”, “travel distance”, and “cadence”. For example, by selecting “Cadence” and touching the confirmation button icon 52, the controller MC sets the traveling information to be displayed on the second display screen 18 as cadence data. Thus, for example, the display is as shown in FIG.
d) In the present embodiment, “speed”, “travel distance”, and “cadence” are options that can be displayed on the second display screen 18, and any one of them can be displayed on the second display screen 18. Then, the other two are set to be displayed on the first display screen 17, and when one is newly selected, the display is switched between the first and second display screens 17 and 18. . For example, when it is detected that “speed” is touched, the controller MC displays the second display screen 18 as shown in FIG. 11, for example, and the first display screen 17 has the speed display area 43 as shown in FIG. The cadence display area 53 is displayed instead of “Cadence” instead of “Speed”.
In the cycle computer 10 having such a configuration, any one of the travel information selected from “speed”, “travel distance”, and “cadence” is always displayed on the second display screen 18 by the controller MC in a monochrome 7-segment display. The remaining two pieces of travel information other than the travel information displayed on the second display screen 18 are displayed in color together with the map information on the first display screen 17. Then, when a certain time (30 seconds in the above embodiment) elapses from the normal display mode, the controller MC sets the first display screen 17 to the power consumption suppression mode so that the display content is not visually observed. In addition, when the controller MC detects that the first display screen 17 is touched in the power consumption suppression mode, the controller MC returns the first display screen 17 to the normal display mode and makes it visible together with the second display screen 18.

By configuring as described above, the following effects are exhibited in the present embodiment.
(1) The first display screen 17 is turned off after a certain period of time and enters the power consumption suppression mode. Therefore, the first display screen 17 is a large-screen dot-matrix color display and consumes a relatively large amount of power. Therefore, the power consumption is suppressed. Further, since the second display screen 18 that is always displayed does not consume much power, the total power consumption is greatly improved.
(2) Since any information can be selected and displayed on the second display screen 18 from the three travel information options, the travel information desired to be grasped by the user can always be prioritized and visually checked. There is no problem even if 17 is not always displayed.
(3) Even if the first display screen 17 is not lit, it can be turned on instantly by touching as necessary to enter the normal display mode. Therefore, even if the user wants to check the current position on the map, the user is frustrated. I don't feel it.
(4) By disposing the second display screen 18 in the direction of the user's line of sight, the second display screen 18 that is frequently viewed is easy to see and the stress on the user is reduced. Further, since the second display screen 18 has a narrow vertical width, it can be arranged compactly without interfering with other members on the handlebar H even if it is arranged obliquely in this way.

The present invention may be embodied in the following manner.
In the above embodiment, the time until turning off is 30 seconds, and the first display screen 17 is set so as to return from the normal display mode to the power consumption suppression mode. It is possible to set a different time by changing.
In the above embodiment, the first display screen 17 is turned off as the power consumption suppression mode. However, the luminance may be attenuated instead of turning off.
・ There are three choices for driving information that can be displayed on the second display screen 18: “speed”, “traveling distance”, and “cadence”, but these are only examples, and other driving information is selected. It may be possible.
In the above embodiment, when the travel information on the second display screen 18 is displayed, the travel information is not displayed on the first display screen 17. You may make it display on the display screens 17 and 18.

As shown in FIG. 12, the cycle computer 10 may be configured by switching the first display screen 17 and the second display screen 18 before and after. Further, it may be attached to the stem ST instead of the handle bar H as shown in FIG.
In the above description, the cycle computer 10 is described as an example having two display screens 17 and 18, but it does not exclude models of three or more display screens.
-It is also free to apply to a model provided with a button switch or the like other than the first display screen 17 (touch panel) as input means.
In the above embodiment, the first display screen 17 is a dot-matrix color display that consumes a large amount of power, but if it is relative to the second display screen 18, that is, the first display screen 17. Since the normal power consumption of the second display screen 18 only needs to be larger than that of the second display screen 18, the type and shape of the display device are not particularly limited. In this respect, the second display screen 18 does not have to be displayed in monochrome.
In the above embodiment, the cycle computer 10 is used, but it can also be implemented as a mobile phone or a portable music player.
The shape of the cycle computer 10 of the above embodiment is an example, and can be freely applied to other shapes.
-The present invention can be freely implemented in a modified form without departing from the spirit of the present invention.
