Abstract
A sleep timer for changing a power state of a device includes a detector, a memory, a sleep interval setting unit, a timer, and a power unit. The detector detects interactions between a user and an active device. The memory is linked to the detector and stores the historical user interaction data. Based on the historical user interaction data, the sleep interval setting unit adjusts the sleep timer's sleep interval. The timer determines a power changing point in time based on the sleep interval. At the power state changing point in time, the power unit initiates a power state change.
Claims41
A sleep timer for changing a power state of a device related to a sleep interval, comprising:
- a detector that detects user interactions with the device while the device is in an active state;
- a memory coupled to the detector unit that stores a user interaction data history;
- a sleep interval setting unit that adjusts the sleep interval based on the stored user interaction data history;
- a timer coupled to the memory and to the detector that determines a power state changing point in time based on the sleep interval;
- and
- a power unit coupled to the timer that initiates a power state change of the device.
A method for changing a power state of a device related to a sleep interval, comprising:
- detecting user interactions with the device while the device is in an active state;
- storing a user's interaction data history with the device;
- adjusting the sleep interval based on the stored user's interaction data history;
- determining a power state changing point in time based on the sleep interval;
- and
- initiating the power state change of the device at the power state changing point in time.
A signal-bearing medium having software for changing a power state of a device related to a sleep interval, comprising:
- a detector that converts user interactions into electrical signals;
- an evaluation logic that analyzes a periodicity of the electrical signals;
- a signal analysis logic that sets the sleep interval based on the results of the evaluation logic;
- and
- a power state logic that changes the power state of the device based on the signal analysis logic.
A method for changing a power state of a device related to a sleep interval, comprising:
- detecting user interactions with a device while the device is in an active state;
- storing a user's interaction data history with the device;
- and
- calculating the sleep interval based on the stored user's interaction data history.
