The processor is a general-purpose processor such as a central processing unit (CPU) or a graphics processing unit (GPU), or a dedicated processor specialized for a specific process. The dedicated circuit can be, for example, a field-programmable gate array (FPGA) or an application specific integrated circuit (ASIC). The control unit 21 executes a process related to the operations of the symptom recording apparatus 20 while controlling units of the symptom recording apparatus 20.
The storage unit 22 can include at least one semiconductor memory, at least one magnetic memory, at least one optical memory, or a combination of at least two of these memories. The semiconductor memory can be, for example, a random access memory (RAM) or a read only memory (ROM). The RAM can be, for example, a static random access memory (SRAM) or a dynamic random access memory (DRAM). The ROM can be, for example, an electrically erasable programmable read only memory (EEPROM). The storage unit 22 can function as, for example, a main storage device, an auxiliary storage device, or a cache memory. Data used for the operations of the symptom recording apparatus 20 and data acquired by the operations of the symptom recording apparatus 20 are stored in the storage unit 22.
The communication unit 23 can include at least one communication interface. The communication interface can be, for example, an interface complying with a mobile communication standard such as Long Term Evolution (LTE), 4th Generation (4G), or 5th Generation (5G), an interface complying with short-range wireless communication such as Bluetooth®, or a LAN interface. The communication unit 23 receives the data used for the operations of the symptom recording apparatus 20, and transmits the data acquired by the operations of the symptom recording apparatus 20.
The input unit 24 can include at least one input interface. The input interface can be, for example, a physical key, an electrostatic capacitance key, a pointing device, and a touch screen provided integrally with a display, a camera, or a microphone. The input unit 24 receives an operation of inputting the data used for the operations of the symptom recording apparatus 20. Instead of being provided in the symptom recording apparatus 20, the input unit 24 may be connected to the symptom recording apparatus 20 as an external input device. As a connection method, any method such as universal serial bus (USB), Wi-Fi®, high-definition multimedia interface (HDMI®), or Bluetooth® can be used, for example.
The output unit 25 can include at least one output interface. The output interface ca be, for example, a display or a speaker. The display can be, for example, a liquid crystal display (LCD) or an organic electro luminescence (EL) display. The output unit 25 outputs the data acquired by the operations of the symptom recording apparatus 20. The output unit 25 may be connected to the symptom recording apparatus 20 as an external output device, instead of being provided in the symptom recording apparatus 20. As a connection method, any method such as USB, Wi-Fi®, HDMI®, or Bluetooth® can be used, for example.
Functions of the symptom recording apparatus 20 can be achieved by executing a program according to the present embodiment by a processor as the control unit 21. That is, the functions of the symptom recording apparatus 20 can be achieved by software. The program causes a computer to execute the operations of the symptom recording apparatus 20, thereby causing the computer to function as the symptom recording apparatus 20. That is, the computer functions as the symptom recording apparatus 20 by executing the operations of the symptom recording apparatus 20 according to the program.
The program may be stored in a non-transitory computer-readable medium in advance. The non-transitory computer-readable medium can be, for example, a flash memory, a magnetic recording device, an optical disc, a magneto-optical recording medium, or a ROM. Distribution of the program can be executed by, for example, selling, transferring, or lending a portable medium such as a secure digital (SD) card, a digital versatile disc (DVD) or a compact disc read only memory (CD-ROM) on which the program is stored. The program may be distributed by storing the program in a storage of a server in advance and transferring the program from the server to another computer. The program may be provided as a program product.
For example, the computer temporarily stores, in a main storage device, the program stored in the portable medium or the program transferred from the server. Then, the computer reads, by the processor, the program stored in the main storage device, and executes, by the processor, a process according to the read program. The computer may read the program directly from the portable medium and execute the process according to the program. Each time the program is transferred from the server to the computer, the computer may sequentially execute the process according to the received program. The process may be executed by a so-called application service provider (ASP) type service in which the function is implemented only by execution instruction and result acquisition without transferring the program from the server to the computer. The program includes information that is provided for a process by an electronic computer and that conforms to the program. For example, data that is not a direct command to the computer but has a property that defines a process of the computer corresponds to “information that conforms to the program”.
Some or all of the functions of the symptom recording apparatus 20 may be achieved by a dedicated circuit as the control unit 21. That is, some or all of the functions of the symptom recording apparatus 20 may be achieved by hardware.
The operations of the symptom recording apparatus 20 according to the present embodiment will be described with reference to
