An information processing apparatus includes: a main control unit that executes processing based on an operating system (OS) and that changes to a low power consumption mode to stop some functions including a display unit while making a predetermined function work; a setting information storage unit that stores a usage status mode based on usage status and setting information in association with one another, where the setting information indicates whether to stop the predetermined function implemented by a device driver added to the OS in the low power consumption mode; a mode control unit that changes the main control unit to the low power consumption mode; and a change processing unit that changes a stopped state of the predetermined function.

A method, a computer-readable medium, and an apparatus for power management are provided. The apparatus may determine an activation distance based on operator behavior in relation to operating the apparatus. The apparatus may detect the presence of an approaching operator at the activation distance. The apparatus may wake up from a low-power state in response to the detecting of the presence of the approaching operator at the activation distance. The apparatus may determine a deactivation distance based on the operator behavior. The apparatus may detect the presence of a departing operator of the apparatus at the deactivation distance. The apparatus may enter into the low-power state in response to the detecting of the presence of the departing operator at the deactivation distance.

Systems and methods are disclosed for a mechanical switch that may include receiving an input from a user of a smart keyboard causing the mechanical switch to be in a closed position causing a microcontroller unit to be in an on state and the smart keyboard to be electrically enabled for use; monitoring the smart keyboard for additional input from the user; determining if a first threshold period has occurred in which the additional input from the user has ended; causing the microcontroller unit to be in an idle state; determining if a second threshold period has occurred in which the first threshold period has ended; causing the mechanical switch of the smart keyboard to be in an open position causing the microcontroller unit to be in an off state and the smart keyboard to be electrically disabled for use.

A remote control device according to an embodiment includes an operation button, a generator, an electrical storage part, electronic paper, and a controller. The operation button is for remotely operating a wet-area device. The generator generates electrical power by utilizing energy when the operation button is pressed. The electrical storage part stores the electrical power. The electronic paper displays a setting state of the wet-area device. The controller controls a refresh and a display-switching of the electronic paper by utilizing the electrical power stored in the electrical storage part. The controller starts the refresh in a first state by performing a first determination determining whether or not the electrical power stored in the electrical storage part is in the first state. The electrical power stored in the electrical storage part in the first state is larger than electrical power necessary to complete the refresh.
