Abstract

In an embodiment, an apparatus includes a processor including logic to determine from data received from one or more sensors, whether the apparatus is in physical contact with a user. The logic is further to set a power management policy of the apparatus based on a processor context, where the processor context is determined based at least in part on whether the apparatus is in physical contact with the user, and where the power management policy is used by the logic to determine a level of power consumption at which to operate the processor. Other embodiments are described and claimed.

First claim

What is claimed is:

1. A wearable device comprising:
a touch sensitive screen;
one or more sensors to detect, over a period of time, a change in an orientation of the wearable device from a first orientation to a second orientation; and
a processor to cause to:
alter a display on the touch sensitive screen, in response to detection by the one or more sensors the change in the orientation of the wearable device; and
change a power management policy, in response to the detection by the one or more sensors the change in the orientation of the wearable device,
wherein:
the one or more sensors are to detect, over the period of time, that the wearable device is in physical contact with a user;
the one or more sensors include a specific absorption rate sensor to indicate whether an object that is in close proximity to the one or more sensors is human skin, word, or air; and
the power management policy is reactive in that the power management policy reacts to:
context change of the wearable device;
thermal state of the wearable device; and
power state of one or more components of the wearable device, wherein the power state includes wake state and sleep state.

2. The wearable device of claim 1 , wherein the processor is to:
change a state of the device, in response to the detection of the one or more sensors the change in the orientation of the wearable device.

3. The wearable device of claim 1 , wherein to cause to alter the display on the screen, the processor is to:
cause to display a visual indicator on the screen.

4. The wearable device of claim 1 , wherein to cause to alter the display on the screen, the processor is to:
cause to display a user interface on the screen.

5. The wearable device of claim 1 , wherein the one or more sensors comprises an accelerometer.

6. The wearable device of claim 1 , wherein the one or more sensors comprises a gyroscope.

7. The wearable device of claim 1 , further comprising:
a Global Positioning System (GPS) receiver.

8. A system comprising:
a memory to store instructions;
a processor coupled to the memory;
a screen; and
a wireless interface to allow the processor to communicate with another system,
wherein the processor is to:
access measurements from one or more sensors indicative, over a period of time, a change in an orientation of the system from a first orientation to a second orientation,
cause to display a user interface on the screen, in response to the access of the measurements; and
change a power management policy, in response to the detection by the one or more sensors the change in the orientation of the system;
wherein:
the one or more sensors are to detect, over the period of time, that the system is in physical contact with a user;
the one or more sensors include a specific absorption rate sensor to indicate whether an object that is in close proximity to the one or more sensors is human skin, word, or air; and
the power management policy is reactive in that the power management policy reacts to:
context change of the system;
thermal state of the system; and
power state of one or more components of the system, wherein the power state includes wake state and sleep state.

9. The system of claim 8 , further comprising:
the one or more sensors.

10. The system of claim 9 , wherein the one or more sensors comprises:
at least one of an accelerometer or a gyroscope.

11. The system of claim 9 , wherein the screen is a touch sensitive screen.

12. The system of claim 9 , wherein the first orientation is a vertical orientation, and the second orientation is a horizontal orientation.

13. The system of claim 9 , wherein the system is a wearable device.

14. The system of claim 9 , wherein the processor is to access further measurements of the system being in physical contact with a user over the period of time.

15. An apparatus comprising:
a touch sensitive screen;
one or more sensors to detect that:
the apparatus is in physical contact with a user and at a first orientation during a first time, and
the apparatus is in physical contact with the user and at a second orientation during a second time, the second orientation being different from the first orientation, wherein the one or more sensors include a specific absorption rate sensor to indicate whether an object that is in close proximity to the one or more sensors is human skin, word, or air; and

a processor to:
display a visual indicator on the screen, in response to the detections by the one or more sensors; and
change a power management policy, in response to the detection by the one or more sensors the change in the orientation of the apparatus, wherein the power management policy is reactive in that the power management policy reacts to:
context change of the system;
thermal state of the system; and
power state of one or more components of the system, wherein the power state includes wake state and sleep state.

16. The apparatus of claim 15 , wherein the one or more sensors comprises:
at least one of an accelerometer or a gyroscope.

17. Non-transitory computer-readable storage medium to store instructions that, when executed by a processor within a computing device, cause the processor to perform one or more operations comprising:
access first measurements from first one or more sensors indicating, over a first period of time, that a wearable device is in physical contact with a user, wherein the first one or more sensors include a specific absorption rate sensor to indicate whether an object that is in close proximity to the one or more sensors is human skin, word, or air;
change first power management parameters, based at least in part on access of the first measurements;
access second measurements from second one or more sensors indicating, over a second period of time, a change in an orientation of the wearable device from a first orientation to a second orientation; and
change second power management parameters, based at least in part on access of the second measurements,
wherein the first and second power management parameters are part of a power management policy which is reactive in that the power management policy reacts to:
context change of the wearable device;
thermal state of the wearable device; and
power state of one or more components of the system, wherein the power state includes wake state and sleep state.

18. The non-transitory computer-readable storage medium of claim 17 , wherein to change second the power management parameters, the instructions further cause the processor to perform one or more operations comprising:
display, on a display screen, a user interface to provide information to the user and to receive instructions from the user.

19. The non-transitory computer-readable storage medium of claim 18 , wherein to access second measurements from the second one or more sensors, the instructions further cause the processor to perform one or more operations comprising:
access a series of measurements from the second one or more sensors indicating, in a serial fashion, the change in the orientation of the wearable device from the first orientation to the second orientation.
