First Embodiment
A medical image processing apparatus according to a first embodiment will be described with reference to the block diagram of FIG.
1 includes a processing circuit 10, a memory 11, an input interface 12, a communication interface 13, and a display 14. The processing circuit 10, the memory 11, the input interface 12, the communication interface 13, and the display 14 are communicatively connected to each other via a bus, for example.

The processing circuit 10 is a processor that functions as the core of the medical information processing device 1. The processing circuit 10 is, for example, a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). The processing circuit 10 includes an acquisition function 101, a specification function 102, an update function 103, and a display control function 104.

The acquisition function 101 acquires an input signal related to at least one of a treatment and an examination for a subject. The input signal may be, for example, a voice signal or a keyboard input.

The identification function 102 identifies the procedure or test that has been performed and the next procedure or test to be performed based on the input signal.

The update function 103 updates the remaining time or elapsed time displayed on the display screen.

The display control function 104 causes the remaining time for the next procedure or examination to be performed and the type of procedure or examination that has been performed to be displayed, for example, on the display 14. The display control function 104 also causes the display 14 to display a timeline showing the status of the procedure or examination, including the time at which the procedure or examination was performed.

The memory 11 is a storage device such as a ROM (Read Only Memory), a RAM (Random Access Memory), a HDD (Hard Disk Drive), a SSD (Solid State Drive), or an integrated circuit storage device that stores various information such as a patient's biological information and guidelines regarding the treatment or examination of a subject. The memory 11 may also be a drive device that reads and writes various information to and from a portable storage medium such as a CD-ROM drive, a DVD drive, or a flash memory. The memory 11 does not necessarily have to be realized by a single storage device. For example, the memory 11 may be realized by multiple storage devices. The memory 11 may also be in another computer connected to the medical information processing device 1 via a network.

The memory 11 stores a program for executing the processing according to this embodiment. Note that this program may be stored in advance in the memory 11, for example. Also, for example, the program may be stored in a non-transient storage medium and distributed, and may be read from the non-transient storage medium and installed in the memory 11.

The input interface 12 accepts various input operations from a user, converts the accepted input operations into electrical signals, and outputs the electrical signals to the processing circuit 10. The input interface 12 according to this embodiment is connected to input devices such as a mouse, keyboard, trackball, switch, button, joystick, touchpad, and touch panel whose operation surface is touched to input instructions. The input devices connected to the input interface 12 may also be input devices provided in another computer connected via a network or the like.

The communication interface 13 performs data communication between the medical information processing device 1 and the outside. For example, data communication is performed with a hospital information system, a radiology department information system, etc., which are not shown. The communication interface 13 performs communication in accordance with a known standard that is set in advance, such as HL7 (Health Level 7) or DICOM (Digital Imaging and Communications in Medicine).

Next, the operation of the medical information processing device 1 according to the first embodiment will be described with reference to the flowchart in FIG. 2. In the following, processing in cardiac arrest mode (hereinafter referred to as CPA mode) is assumed, and it is assumed that the display screen for emergency mode has been set in advance. On the display screen for emergency mode, for example, time-series data of vital signs is displayed.

In step SA1, the processing circuit 10 acquires a mode change input from the user by the acquisition function 101. For example, when the user utters "cardiac arrest mode" or "CPA (cardiopulmonary arrest) mode," the input for changing the mode is accepted as an input for changing the mode. Note that the input is not limited to an input from the user, and a signal from another device may be used as the trigger for switching. Specifically, for example, when the heart rate measured by an electrocardiograph becomes zero, a trigger signal for switching to the CPA mode is transmitted, and the acquisition function 101 determines that an input for changing the mode has been made and switches from the emergency mode to the CPA mode.

In step SA2, the display control function 104 causes the processing circuit 10 to switch the screen display from the emergency mode screen to the CPA mode screen, and on the CPA mode display screen, a timer that counts up the elapsed time since the mode change or various events, and a timer that counts down the remaining time until various events are displayed. An event indicates a treatment or examination for the patient.

In step SA3, the display control function 104 causes the processing circuit 10 to count up the elapsed time using a timer, or to count down the remaining time using a timer, depending on the event type.

In step SA4, the processing circuit 10 uses the identification function 102 to identify whether there is an input related to a treatment or examination for the patient based on an input signal from the user. For example, if a medical professional speaks about a specific treatment or examination, it determines that there is an input. If there is an input, proceed to step SA5, and if there is no input, wait until there is an input. As in step SA1, it may be possible to identify whether there is an input related to treatment and examination for the patient based on the presence or absence of a signal from another device. For example, in a situation where an ECMO (extracorporeal membrane oxygenation) is attached to the patient, an ECMO activation signal is transmitted to the medical information processing device 1. The processing circuit 10 uses the identification function 102 to identify that the activation signal has started ECMO treatment for the patient and that an input for treatment for the patient has been received.

In step SA5, the display control function 104 causes the processing circuit 10 to display an icon indicating the procedure or examination that was performed on the display screen.

In step SA6, the display control function 104 causes the processing circuit 10 to reset the timer for the corresponding treatment or examination and restart the count. If the same treatment or examination as the timer displaying the remaining time until the next treatment or examination is performed again, the display control function 104 causes the processing circuit 10 to update the remaining time on the timer.

In step SA7, the processing circuit 10 uses the identification function 102 to identify whether or not treatment of the subject has been completed. For example, when a specific input signal is acquired from a medical professional, it is determined that treatment of the subject has been completed. Specifically, when the heartbeat has resumed and the medical professional utters the words "restart of heartbeat," it is determined that cardiac arrest treatment of the patient has been completed. If the event has ended, the process proceeds to step SA9, and if treatment has not ended, the process proceeds to step SA8.

In step SA8, the processing circuit 10 uses the identification function 102 to identify the procedure or examination that has been performed and the procedure or examination that will be performed next based on the input signal. The display control function 104 causes the processing circuit 10 to display the remaining time until the next procedure or examination as if it were being counted by a timer.

In step SA9, the display control function 104 causes the processing circuit 10 to switch the screen display from CPA mode to emergency mode.

Next, a display example of the emergency mode according to the first embodiment will be described with reference to FIG.
3 is an example of a display screen, and is a display example of a first display area 31 and a second display area 32. The first display area 31 displays time series data 33 of vital signs (blood pressure, pulse rate, etc.), and the second display area 32 displays time series data of specific biological information.

The most recent measured value of vital data and biological information is displayed at the right end of the display area, and the time series data is updated from right to left. In the example of Fig. 3, biological information of " _pO2 (a,T)/ _FO2 " and "cTHb" are displayed in the second display area 32.

Next, a first display example of the CPA mode according to the first embodiment will be described with reference to FIG.
On the display screen 40 in the CPA mode, a timeline is displayed at the top and a number of timers are displayed at the bottom.

An icon 42 is displayed on the timeline, indicating that the CPA mode has started. As in FIG. 3, the most recent measurement value is at the right end of the display area, and the time series data is updated from right to left, with the icon moving from right to left each time the data is updated. The timeline displays an icon display area for each event 41. In the example of FIG. 4, four events 41 are displayed: "Rhythm," "Defibrillation," "Adrenaline," and "Treatment."

Timer 43 counts up the time that has elapsed since the start of treatment or the time that has elapsed since the implementation of an event. Timer 44 counts down the remaining time after the implementation of an event. In the example of FIG. 4, timer 43 counts up the time that has elapsed since the start of CPA and the time that has elapsed since the event "intubation", and timer 44 counts down the remaining time until the next events related to "rhythm check" and "adrenaline administration" are implemented. In addition, an event 41 on the timeline and the timer for that event 41 may be associated with each other and colored the same, and each event 41 may be colored in a different color.

Note that timer 43 and timer 44 are shown as an example displayed in card format with a set of information indicating whether the time has elapsed or the time remaining, the type of event 41, and time information, but the number of times event 41 has been performed and biological information of the subject related to the event may also be displayed. Furthermore, this information may be displayed in a table format, not limited to a card format. In other words, any display format may be used as long as it is possible to know which event the timer relates to.

In addition, the arrangement of the timeline and timers 43, 44 is not limited to the example in FIG. 4, and the timers 43, 44 may be arranged vertically, for example.

Next, a second display example in the CPA mode according to the first embodiment will be described with reference to FIG.
In the example of Fig. 5, when a medical professional utters a rhythm check-related utterance such as "Rhythm,""Synthesis,""Asis,""V-T,""Myaku-A-V-T," or "Myaku-Nashi-V-T," the processing circuit 10 uses the identification function 102 to identify the event that has been performed from the utterance. Here, the utterance is identified as being related to a rhythm check, and the processing circuit 10 uses the display control function 104 to display an icon 51 indicating that a rhythm check has been performed on the timeline for "Rhythm." Note that the shape of the icon shown in Fig. 6 and subsequent figures is not limited to the example of the icon 51, and may be any shape that can be distinguished from other events.

In addition, when a rhythm check is performed, the processing circuit 10, via the display control function 104, resets the timer 44 related to the rhythm check and updates it so that it starts counting down from the set value until the next rhythm check. In this case, the set value of the timer 44 is two minutes, and when a rhythm check is performed by the above-mentioned utterance, the timer 44 counts down again from two minutes.

Next, a third display example in the CPA mode according to the first embodiment will be described with reference to FIG.
In the example of Fig. 6, when a medical professional utters adrenaline administration such as "adrenaline,""ade,""epinephrine,""epi," or "bosmin," the processing circuit 10 uses the identification function 102 to identify the event that was performed from the utterance. Here, the utterance is identified as being related to adrenaline administration, and the processing circuit 10 uses the display control function 104 to display an icon 52 indicating that adrenaline administration has been performed on the timeline for "adrenaline." The icon 52 also displays the number of times the administration has been performed ("1" in the example of Fig. 6).

In addition, when an adrenaline injection is performed, the processing circuit 10, via the display control function 104, resets the timer 44 related to the injection of adrenaline, as in FIG. 5, and updates it so that it starts counting down from the set value until the next injection of adrenaline.

Next, a fourth display example in the CPA mode according to the first embodiment will be described with reference to FIG.
7 shows an example in which the timer 71 relating to the rhythm check is highlighted because the remaining time until the next rhythm check shown in FIG. 5 is less than or equal to a predetermined time. Specifically, assuming that the predetermined time is set to 30 seconds, the processing circuit 10 highlights the timer 71 relating to the rhythm check by using the display control function 104 because the remaining time until the next rhythm check is less than or equal to 30 seconds. Note that the entire timer 71 may be highlighted, or the time information text may be colored red, or a voice message such as "30 seconds left until the next rhythm check" may be output to notify the medical staff. Furthermore, when the timer reaches zero, i.e., when the time to start the event is reached, a voice message such as "Rhythm check, timer is over" or "Time is up, start rhythm check" may be output.

If there are multiple timers that have reached the specified time and the timing of the read-aloud audio overlaps, the read-aloud audio of the timer that output the read-aloud audio first is given priority, and after the read-aloud audio is finished, the read-aloud audio for the other timer is output. In this way, any notification method is acceptable as long as it can notify medical personnel that the time for the next event is approaching.

Next, a fifth display example in the CPA mode according to the first embodiment will be described with reference to FIG.
The above-mentioned examples of Figures 5 to 7 show examples in which an icon is displayed when an event has been carried out, whereas the example of Figure 8 shows icons displayed on the timeline for events that are to be carried out or may occur in the future.

Specifically, a bar 81 indicating the current time is displayed on a timeline. Icons relating to past events (e.g., icons 51, 52) are displayed on the left side of the bar 81, and the right side of the bar 81 is a schedule display area 85 in which icons indicating upcoming events are displayed. Specifically, rhythm check icon 51 is displayed on the left side of the bar 81 and has already been performed. Meanwhile, rhythm check icon 53 and defibrillation icon 54 are displayed in the schedule display area 85 and are events that are scheduled to be performed in the future. By displaying in this manner, the next scheduled event can be easily identified by the icons.

For events to be performed, the processing circuit 10 uses the identification function 102 to refer to guidelines stored in the memory 11, for example, and identifies one or more events to be performed next from among events that have already been performed, in accordance with the guidelines for performing cardiopulmonary resuscitation from a state of cardiac arrest. Then, the processing circuit 10 uses the display control function 104 to display icons corresponding to the identified events on a timeline in the order of performance and the interval between performance.

The display control function 104 may cause the processing circuit 10 to update the events scheduled to be performed as appropriate, depending on the events performed by the medical staff. For example, in a guideline for performing cardiopulmonary resuscitation, the flow may branch depending on the results of the event. Therefore, the identification function 102 allows the processing circuit 10 to identify the branch destination flow of the next event to be performed from the results of the event input by the medical staff, and the display control function 104 allows the processing circuit 10 to display the events related to the branch destination flow as icons on the timeline.

In addition, the content of the next event to be performed and the remaining time set in the timer 44 may be changed depending on the number of events that have been performed. For example, when changing the content of the event, the processing circuit 10 may change from a simple inspection to a detailed inspection by the update function 103 if the event has been performed a predetermined number of times. When changing the remaining time in the timer 44, the processing circuit 10 may increase the setting value of the remaining time in the timer 44 by the update function 103 so as to lengthen the time interval until the next event is performed.

Next, a sixth display example in the CPA mode according to the first embodiment will be described with reference to FIG.
Here we will show an example of displaying multiple types of icons in a row, rather than using separate rows on the timeline to display icons for each event. By displaying them in a row, it is easier to understand the chronological order of events.

Next, a display example of auxiliary information in the CPA mode will be described with reference to FIG.
Fig. 10 shows an example of displaying in parallel the display screen 40 in the CPA mode as shown in Figs. 4 to 9 and a flowchart 91 showing a workflow according to a guideline. In the example of Fig. 10, the flowchart 91 shows a flowchart of a cardiac arrest algorithm according to a guideline defined by, for example, a cardiac academic society or association. By referring to the displayed flowchart 91 while performing a procedure or examination related to an event, medical personnel can easily confirm the workflow, which helps to speed up the procedure.

Furthermore, the display control function 104 may cause the processing circuit 10 to highlight on the flowchart 91 the workflow event 92 corresponding to the most recently performed event. This allows the medical staff to easily understand which event is currently being performed. The next event to be performed may also be highlighted, not limited to the current treatment or examination. Note that the display format is not limited to a flowchart format, and the guidelines or workflow may be displayed in a list format, and any display format may be used as long as the workflow can be recognized.

Next, another example of the auxiliary information in the CPA mode will be described with reference to FIG.
The timer counts the remaining time until the next event, but if the event is carried out at a time outside the allowable range based on the expected time of the next event, i.e., earlier or later than a specified time, a message 1101 is displayed to prompt the user to check whether there is a problem with the timing of the event.

11, it is assumed that a rhythm check event is performed before a predetermined time has elapsed on a timer that counts down the remaining time. In this case, the display control function 104 causes the processing circuit 10 to display on the screen a message 1101 including the content "It seems that the rhythm check was performed earlier than the standard. Is this correct?"
This will prompt medical personnel to check whether the event is being carried out correctly.

When switching from the CPA mode to the emergency mode screen display, the period during which the CPA mode was in operation may be displayed on the emergency mode screen.

An example of a display in the emergency mode that displays the implementation period of the CPA mode will be described with reference to FIG.
Fig. 12 shows an example in which the implementation period 35 of the CPA mode is displayed by diagonal lines in the first display area 31 that displays vital signs in the same manner as in Fig. 3. Of course, the implementation period 35 of the CPA mode may be displayed in a manner that allows distinction between the implementation period 35 of the CPA mode and other periods, such as by changing the background color of the implementation period 35 or by making it blink. This allows the user to easily know in which period CPA occurred just by looking at the display screen in the emergency mode.

In the above example, a display example related to cardiac arrest (CPA) was shown, but the present invention is not limited to this. The medical information processing device according to this embodiment can similarly support other medical procedures, not limited to emergency care, such as administering medication in an intensive care unit (ICU) and managing events such as checking vital signs.

The processing of the medical information processing apparatus 1 will be described with reference to FIG. 13 with respect to a display example used for treatment or examination after surgery.
13 is a display screen relating to post-operative blood glucose monitoring. The upper part of the display screen displays a timeline of events relating to blood glucose checks, insulin administration, and glucose administration. The lower part of the display screen displays a timer showing the time elapsed since surgery, the time remaining until a blood glucose check, and the time remaining until medication (e.g., insulin) are administered. An icon 55 for checking blood glucose levels and an icon 56 for administering insulin are displayed, allowing the user to know that each has been performed once. In this way, the medical information processing device 1 according to this embodiment can also be used for postoperative follow-up observation.

Next, an example in which the processing of the medical information processing apparatus 1 is used for a contrast imaging protocol will be described with reference to FIG.
FIG. 14 is an example of displaying the timing from the injection of the contrast agent to the actual imaging with a timeline and a timer. The upper part of the display screen displays a timeline of events related to the contrast agent and the actual imaging. The lower part of the display screen displays the elapsed time from the start of the examination, the elapsed time from the injection of the contrast agent, the remaining time until the early phase, and the remaining time until the late phase. In the example of FIG. 14, an icon 57 indicating the injection of the contrast agent is displayed on the timeline. Also, an icon 58 indicating the timing of the early phase and an icon 59 indicating the timing of the equilibrium phase are displayed on the timeline. In this way, a timer indicating the remaining time from the injection of the contrast agent to the actual imaging may be displayed together with a timeline indicating the progress of the imaging protocol (a list of events such as the injection of the contrast agent and imaging).

Next, an example in which the processing of the medical information processing device 1 is used for hospitalization management will be described with reference to FIG.
FIG. 15 shows an example of displaying the timing of various events on a timeline and a timer, taking as an example an inpatient who needs rehabilitation due to surgery for fractures or ligament damage. The upper part of the display screen displays a timeline of events related to rehabilitation and taking medicine (or medication). The lower part of the display screen displays the number of days since admission, the remaining time until rehabilitation begins, and the remaining time until medication is taken. In the example of FIG. 14, an icon 58 indicating that rehabilitation has been performed and an icon 59 indicating that medication has been taken are displayed on the timeline. Furthermore, timelines and timers for other events such as vital signs checks may also be displayed in the same way. This allows the patient to be notified of the timing of rehabilitation and medication, which should be managed by the patient himself. This makes it possible to prevent forgetting to take medicine, and to manage events that need to be performed periodically.

The event management of the medical information processing device 1, as typified by the rehabilitation and medication management described above, can be similarly applied not only to hospitalized patients but also to remote medical care such as home medical care.

In the above example, switching between emergency mode and CPA mode was described as an example, but the workflow may be switched in response to specific circumstances, such as rare cases. Specifically, the workflow may be switched when the treatment method changes due to a specific situation or change in some condition, such as when the patient falls off the bed, the patient's condition changes suddenly, or a patient is treated as having a myocardial infarction but actually has a cerebral infarction.

The display control function 104 may cause the processing circuit to switch the display screen of a timeline of a procedure or examination related to a workflow event to a display screen of a timeline of a procedure or examination related to a different workflow event when a specific situation occurs in at least one of the patient who is the subject and the situation in the room, such as an operating room, in which the patient is present.

The display screen may be switched by, for example, switching the workflow in response to a voice, or by detecting a change in the patient's condition. The patient's condition may be detected from the camera image captured by installing a camera capable of capturing images of the room. For example, the patient's condition may be detected by detecting a change in the patient's condition during surgery, or the replacement of a surgical instrument. Furthermore, the workflow may be switched by detecting a change in the situation and the patient's condition (e.g., the heart rate is zero) based on vital signs measured by a vital monitor. Specifically, if the display control function 104 causes the processing circuit 10 to detect cardiac arrest based on vital signs of the heart rate when treating a cerebral infarction, the mode may be switched to CPA mode.

Furthermore, the display control function 104 may cause the processing circuit 10 to input and display events that the system may automatically detect using the camera footage or vital signs monitor described above, such as changing an IV drip, in a manner that makes them distinguishable from user input by a medical professional, such as by displaying them in gray. In this case, the acquisition function 101 may cause the processing circuit 10 to confirm the automatically detected event by accepting a confirmation action, such as touching a specific area of the display or pressing a button, by the medical professional via the input interface 12. Furthermore, inputter information indicating who made the input may be included for all event inputs.

When switching the display screen in response to a workflow switch, the processing circuit 10 may use the update function 103 to reset the timer count or update the count display to continue counting the remaining time depending on the type of specific situation. For example, timers related to the timing of electrocardiograms and vital signs checks may be reset in response to a workflow switch, since there are no restrictions on the number of measurements or the timing of measurements. On the other hand, since there are restrictions on the administration of adrenaline, such as a specified number of times or a specified period of time, it is better to continue counting even when the workflow is switched. Therefore, the remaining time can be carried over and counting can be continued even when the workflow is switched.

A table that associates the type of specific situation with information indicating whether to reset or continue the timer for each workflow can be stored in the memory 11 or the like, and the processing circuit 10 can refer to the table by the update function 103 in response to switching of the workflow to determine whether to reset or continue the timer for the above-mentioned events. In this way, by setting the timer count for the event of the next treatment or examination to be performed according to the type of specific situation, it is possible to support time management appropriate to the situation.

According to the first embodiment described above, the performed treatment or test and the next treatment or test to be performed are identified based on an input signal related to at least one of the treatments and tests performed by a medical professional on a subject. The remaining time related to one or more treatments or tests to be performed next is displayed, and the type of the performed treatment or test is displayed.

This can assist with time management for each event in the workflow, i.e., when and which procedure or examination should be performed.

Second Embodiment
In the second embodiment, a process is assumed in which the event input by voice from a medical professional cannot be identified.

A medical image processing apparatus 1 according to the second embodiment will be described with reference to the block diagram of FIG.
The medical information processing device 1 according to the second embodiment includes a processing circuitry 10, a memory 11, an input interface 12, a communication interface 13, and a display 14. The processing circuitry 10 includes an acquisition function 101, a specification function 102, an update function 103, a display control function 104, an output function 105, a voice recognition function 106, a calculation function 107, and a generation function 108.

When the processing circuit 10 receives voice input from the medical staff but is unable to acquire the voice input due to, for example, an inability to recognize the voice due to ambient noise, the specific function 102 generates confirmation information for acquiring the voice input again. The confirmation information may be a message that encourages the medical staff to speak, such as "I couldn't hear you. Please speak again." Alternatively, the confirmation information may be a message that encourages the medical staff to input via another input means, such as "I couldn't hear you. Please select an event."

The output function 105 causes the processing circuit 10 to output the confirmation information generated by the specific function 102 to the outside via an output device (not shown) such as a speaker as a synthesized voice.

The speech recognition function 106 allows the processing circuit 10 to recognize the speech input of the medical professional and obtain the speech recognition results.

Using the calculation function 107, the processing circuit 10 calculates the difference between the time when the voice recognition result is obtained by the voice recognition function 106 and the expected time of the next event to be performed.

If the difference is within the threshold, the processing circuit 10 generates confirmation information by the generation function 108 as to whether the voice input is the next event to be performed. The confirmation information may be, for example, a message for confirming the specified event, such as "Are you sure you want to administer medication?".

The display control function 104 causes the processing circuit 10 to display the confirmation information on the screen. In addition, the output function 105 causes the processing circuit 10 to output a synthesized voice related to the confirmation information to the outside via an output device.

Instead of displaying the confirmation information, the event acquired as the voice recognition result may be displayed with a gray icon on the screen, since it is highly likely that the event is an event at the expected time. In this case, the acquisition function 101 may cause the processing circuit 10 to confirm the automatically detected event by receiving a confirmation action, such as touching a specified area of the display or pressing a button, by the medical staff via the input interface 12. Alternatively, if the remaining time on the timer reaches zero and no input is made even after a specified period of time has passed since the time when the event should have been input, the display control function 104 causes the processing circuit 10 to prompt the medical staff to input or retake the event.

According to the second embodiment described above, if the event input by the user's voice cannot be identified, the generation function provides feedback to the user to encourage re-input and correct input. Alternatively, the difference between the time when the voice recognition result was obtained and the next event close to that time is referenced, and if the difference is within a threshold, the event that should be entered is identified and the event is asked again. This allows accurate event input and timer counting, and supports time management in the same way as the first embodiment.

The term "processor" used in the above description means a circuit such as a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an Application Specific Integrated Circuit (ASIC), or a programmable logic device (e.g., a Simple Programmable Logic Device (SPLD), a Complex Programmable Logic Device (CPLD), and a Field Programmable Gate Array (FPGA)). When the processor is a CPU, for example, the processor realizes a function by reading and executing a program stored in a memory circuit. On the other hand, when the processor is an ASIC, for example, instead of storing the program in a memory circuit, the function is directly incorporated as a logic circuit in the circuit of the processor. Note that each processor in this embodiment is not limited to being configured as a single circuit for each processor, but may be configured as a single processor by combining multiple independent circuits to realize its function. Furthermore, multiple components in the figure may be integrated into a single processor to realize its function.

In addition, each function according to the embodiment can be realized by installing a program that executes the above-mentioned processes in a computer such as a workstation and expanding the program in memory. In this case, the program that can cause the computer to execute the above-mentioned methods can also be stored and distributed on a storage medium such as a magnetic disk (such as a hard disk), an optical disk (such as a CD-ROM or DVD), or a semiconductor memory.

At least one of the embodiments described above can assist with time management.

Although several embodiments have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, modifications, and combinations of embodiments can be made without departing from the spirit of the invention. These embodiments and their modifications are within the scope of the invention and its equivalents as set forth in the claims, as well as the scope and spirit of the invention.
