Methods and systems for application procedure management are provided.
The system for application procedure management 100 comprises a sensor 110, a storage unit 120, a display unit 130, a speaker unit 140, and a processing unit 150. The sensor 110 can detect a presence of at least one object. That is, the sensor 110 can detect whether the object is close to the electronic device. For example, when the electronic device is placed in a pocket or a bag, the sensor 110 can detect the presence of the object. In some embodiments, the sensor 110 may be an infrared proximity sensor set nearby the earphone (not shown) of the electronic device. The storage unit 120 can store a normal procedure 121 and a specific procedure 122 for a respective event, as shown in
In step S310, an event is received. As described, the event may be pressing at least one physical button of the electronic device, and/or a reception of an event, such as an incoming call or a notification requesting to activate the display unit 130. In step S320, in response to the event, the sensor 110 is activated (turned on) to detect a presence of at least one object. If the presence of the object is not detected by the sensor 110 (No in step S330), in step S340, the normal procedure for the event is performed. If the presence of the object is detected by the sensor 110 (Yes in step S330), in step S350, the specific procedure for the event is performed. As described, the normal procedure can define execution steps needed to be performed when the corresponding event is received, wherein each step can comprise at least one operation, the hardware required for the operation, and others. The specific procedure may be a subset of the normal procedure. In some embodiments, the performed specific procedure is inactivating the display unit 130, and/or ignoring of the event. Note that, in some embodiments, after the specific procedure is performed, the sensor 110 can be turned off.
In step S410, an event is received. Similarly, the event may be pressing at least one physical button of the electronic device, and/or a reception of an event, such as an incoming call or a notification requesting to activate the display unit 130. In step S420, in response to the event, the sensor 110 is activated to detect a presence of at least one object. If the presence of the object is not detected by the sensor 110 (No in step S430), in step S440, the normal procedure for the event is performed. If the presence of the object is detected by the sensor 110 (Yes in step S430), in step S450, the display unit 130 is inactivated, and/or the event is ignored. Note that, in some embodiments, inactivating the display unit 130 means inactivating a backlight of the display unit 130. It is understood that, in some embodiments, the normal procedure for the event may comprise a step of activation of the display unit 130. When the sensor detects the presence of the object, the execution of at least one operation defined in the normal procedure can be canceled. In other words, the step of activation of the display unit 130 in the normal procedure can be canceled. Note that, in some embodiments, when the sensor detects the presence of the object, in addition to inactivating the display unit 130, and/or ignoring of the event, other steps, such as generation of voices via the speaker unit 140 for the event can be also performed.
In step S510, a physical button of the electronic device is pressed, and in step S520, in response to the press of the physical button, the sensor 110 is activated to detect a presence of at least one object. If the presence of the object is not detected by the sensor 110 (No in step S530), in step S540, a keystroke corresponding to the physical button is transmitted to an OS (Operating System) of the electronic device. Then, in step S560, the sensor 110 is turned off. If the presence of the object is detected by the sensor 110 (Yes in step S530), in step S550, the keystroke corresponding to the physical button is not transmitted to the OS of the electronic device. Then, in step S560, the sensor 110 is turned off. Note that, since the OS does not receive the keystroke corresponding to the physical button, the display unit 130 is not activated.
In step S610, an event, such as an incoming call or a notification requesting to activate the display unit 130 of the electronic device is received. In step S620, in response to the reception of the event, the sensor 110 is activated to detect a presence of at least one object. If the presence of the object is not detected by the sensor 110 (No in step S630), in step S640, the display unit 130 is activated, and in step S660, a voice is generated via the speaker unit 140. If the presence of the object is detected by the sensor 110 (Yes in step S630), in step S650, the display unit 130 is inactivated, and in step S660, a voice is generated via the speaker unit 140. In some embodiments, a crescendo voice can be generated via the speaker unit 140. Note that, in some embodiments, although the display unit is not activated, the speaker unit 140 can be activated according to the operation defined in the normal procedure. In step S670, it is determined whether a predefined period has been passed. It is understood that, in some embodiments, the predefined period may be a display time of the backlight defined by the display unit. If the predefined period has not been passed (No in step S670), the procedure returns to step S630. It is understood that, once the presence of the object is not detected by the sensor 110, the display unit 130 can be activated. If the predefined period has been passed (Yes in step S670), in step S680, the sensor 110 is turned off. It is understood that, in some embodiments, when the event, such as an incoming call or a notification requesting to activate the display unit 130 of the electronic device is terminated, the sensor 110 can be directly turned off.
Note that, in some embodiments, the electronic device may be set into a silent mode and/or a vibrate mode. When the sensor 110 detects the presence of the object, and the electronic device is not in the silent mode, the electronic device will vibrate to notify users of the reception of the event. Additionally, in some embodiments, when the sensor 110 detects the presence of the object, and the electronic device is not in the silent mode and is not placed at a stable horizontal surface, the electronic device will vibrate to notify users of the reception of the event. Note that, in some embodiments, even if the electronic device is set to not vibrate, the electronic device can still vibrate to notify users the reception of the event. Further, when the sensor 110 detects the presence of the object, and the electronic device is not in the silent mode or the vibrate mode and is not placed at a stable horizontal surface, a crescendo voice can be generated via the speaker unit 140 to notify users the reception of the event. Note that, in some embodiments, when the sensor 110 does not detect the presence of the object or when the event, such as an incoming call or a notification requesting to activate the display unit 130 of the electronic device is terminated, the electronic device will stop the generation of the crescendo voice.
Therefore, the methods and systems can perform power management by managing application procedures. When the sensor of the electronic device detects a presence of an object, the display unit can be inactivated, thus saving power consumption for the electronic device.
Methods and systems for application procedure management, or certain aspects or portions thereof, may take the form of a program code (i.e., executable instructions) embodied in tangible media, such as floppy diskettes, CD-ROMS, hard drives, or any other machine-readable storage medium, wherein, when the program code is loaded into and executed by a machine, such as a computer, the machine thereby becomes an apparatus for practicing the methods. The methods may also be embodied in the form of a program code transmitted over some transmission medium, such as electrical wiring or cabling, through fiber optics, or via any other form of transmission, wherein, when the program code is received and loaded into and executed by a machine, such as a computer, the machine becomes an apparatus for practicing the disclosed methods. When implemented on a general-purpose processor, the program code combines with the processor to provide a unique apparatus that operates analogously to application specific logic circuits.
While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. Those who are skilled in this technology can still make various alterations and modifications without departing from the scope and spirit of this invention. Therefore, the scope of the present invention shall be defined and protected by the following claims and their equivalents.
