Abstract
A power usage method is provided for using power supplied from a first device at a second device. The power usage method includes causing the second device to perform an initialization process to obtain a value of a current used when consuming the power at a voltage that is a minimum prerequisite for the second device to perform a predetermined process; and causing the second device to execute the predetermined process while consuming the power in a manner that the current does not exceed the obtained value.
Claims13
A power usage method for using power supplied from a first device at a second device, the power usage method comprising:
- causing the second device to perform an initialization process to obtain a value of a current used when consuming the power at a voltage that is a minimum prerequisite for the second device to perform a predetermined process;
- and
- causing the second device to execute the predetermined process while consuming the power in a manner that the current does not exceed the obtained value.
A slave device that receives power from a host device and performs a predetermined process, the slave device comprising:
- a current obtaining unit that performs an initialization process to obtain a value of a current used when consuming the power at a voltage that is a minimum prerequisite for performing the predetermined process;
- and
- a predetermined process executing unit that executes the predetermined process while consuming the power in a manner that the current does not exceed the obtained value.
A computer-readable recording medium storing a program that causes a device that receives power from a host device to execute a method comprising:
- performing an initialization process to obtain a value of a current used when consuming the power at a voltage that is a minimum prerequisite for performing a predetermined process;
- and
- executing the predetermined process while consuming the power in a manner that the current does not exceed the detected value.
