Abstract
A power feed system includes: an information device; a terminal device that is connected the information processing device, and that has a power source; and a selection unit that selects, as power utilized by the terminal device, at least one of first power from the power source of the terminal device and second power supplied from the information processing device according to an operating state of the terminal device.
Claims15
A power feed system comprising:
- an information processing device;
- a terminal device that is connected to the information processing device, and that has a power source;
- a selection unit that selects, as power utilized by the terminal device, at least one of first power from the power source of the terminal device and second power supplied from the information processing device according to an operating state of the terminal device;
- and
- a control section, wherein
- the control section determines whether or not the second power supplied from the information processing device to the terminal device exceeds a predetermined level, and
- if the control section determines that the second power exceeds the predetermined level, the control section causes the selection unit to select at least the first power,
- wherein when a predetermined time is exceeded, the power source switches to the second power supplied by the information processing device.
A terminal device comprising:
- a power source section;
- a selection section that selects, as power to be utilized, third power supplied from another connected device, fourth power from the power source section, or both of the third and fourth power;
- and
- a control section, wherein
- the control section determines whether or not the third power supplied from said another connected device to the terminal device exceeds a predetermined level, and
- if the control section determines that the third power exceeds the predetermined level, the control section causes the selection unit to select at least the fourth power,
- wherein when a predetermined time is exceeded, the power source switches to the third power supplied by the another connected device.
A terminal device comprising:
- a power source section;
- a power feed section that supplies power to a first device to be connected;
- and
- a selection section that selects, as power supplied from the power feed section to the first device, fifth power supplied from a second device to be connected, sixth power from the power source section, or both of the fifth and sixth power;
- and
- a control section, wherein
- the control section determines whether or not the fifth power supplied from the second device to the terminal device exceeds a predetermined level, and
- if the control section determines that the fifth power exceeds the predetermined level, the control section causes the selection unit to select at least the sixth power,
- wherein when a predetermined time is exceeded, the power source switches to the fifth power supplied by the second device.
A power feeding method comprising:
- determining whether or not seventh power supplied to a terminal device having a power source section from another terminal device connected to the terminal device through a power line exceeds a predetermined level;
- if it is determined that the seventh power exceeds the predetermined level, selecting, as power to be used by the terminal device at least eighth power from the power source section of the terminal device;
- and
- switching the power to be used by the terminal device to the seventh power source when a predetermined amount of time is exceeded.
A non-transitory computer readable medium storing a program causing a computer, which is provided in a terminal device being connected to another terminal device through a power line and having a power source section, to execute a process for supplying electric power to the terminal device according to a required amount, the process comprising:
- determining whether or not ninth power supplied to a terminal device having a power source section from another terminal device connected to the terminal device through a power line exceeds a predetermined level;
- selecting, as power to be used by the terminal device, at least tenth power from the power source section of the terminal device;
- and
- switching the power to be used by the terminal device to the ninth power source when a predetermined amount of time is exceeded.
