Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus identifies load and store operations in program code that access an array of structures. The apparatus assigns metadata to each of the identified load and store operations. The metadata associated with each operation represents a structure of the array. The apparatus generates oracle conditions for the program code based on the metadata to facilitate register promotion. One or more indices of the array accessed by the load and store operations are not known at compile time.

Abstract: The present invention provides a touch electronic device and a touch link method. The touch electronic device includes a touch panel and a touch connection module. The touch connection module includes a sensing module and a connection module. The sensing module is utilized to detect a physical adjacency between the touch electronic device and a plurality of first touch electronic devices. The connection module is utilized to develop a touch link between the touch electronic device and the plurality of first touch electronic devices through the touch panel when the sensing module detects the physical adjacency. The touch electronic device and the touch link method of the preset invention could be utilized to easily develop the touch link among at least two electronic devices for data transmission.

Abstract: A system for changing the display direction of a screen includes a gravity sensor, a control key unit, a display control unit, and a control mode choice unit. The gravity sensor is adapted to generate gravity-sensing signals according to the orientation of the screen. The control key unit is adapted to generate a control instruction. The control mode choice unit is connected to the gravity sensor and the control key unit. The control mode choice unit is adapted to send either the gravity sensed signal from the gravity sensor or the control instruction from the control key unit to the display control unit. The display control unit is adapted to control the display direction of the screen according to either the gravity sensed signal or the control instruction.

Abstract: A system for generating click input signal for optical finger navigation, includes a touch sensor, a timing unit, and a control unit. The touch sensor is adapted to sense whether a finger presses thereon. The timing unit is adapted to time a duration time of the finger pressing on the touch sensor when the finger presses on the touch sensor. The control unit is adapted to generate a first click signal when the duration time is greater than a threshold value and generate a second click signal when the duration time is smaller than a threshold value.

Abstract: A system for managing power supply of a mobile device, includes a random access memory, a storage device, and a battery. The random access memory will not store information therein without power. The storage device can store information therein regardless of power supplied to the storage device. The storage device is connected to the random access memory. The storage device includes an image area. The battery is connected to the random access memory and the storage device. The mobile device is configured to work between a normal mode and a first power-saving mode. In the normal mode, the battery supplies power to the random access memory. In the first power-saving mode, information stored in the random access memory is copied into the image area, and the battery stops providing power to the random access memory.

Abstract: A power supply system includes an adapter adapted to covert AC power into DC power, a power supply chipset connected to the adapter, a main battery, a slave battery, and a control chipset connected to the power supply chipset, the main battery, and the slave battery. The power supply chipset is adapted to receive DC power provided by the adapter. The control chipset is configured to monitor whether the power supply chipset receives DC power. The power supply chipset can provide DC power to the electronic device system and charge the main battery and the slave battery when the power supply chipset receives DC power. The power supply chipset also can control the main battery and the slave battery providing power to the electronic device system when the power supply chipset does not receive DC power.

Abstract: An electronic device includes a storing module, an accelerometer, a first audio output module, and a control module. The storing module is configured to store a reference angle. The accelerometer is configured to sense acceleration of the electronic device along three axes X, Y, Z, wherein the X, Y, Z axes are all perpendicular to each other. The first audio output module is configured to output audio signals. The control module is configured to obtain an angle of rotation of the electronic device according to the values, and turn the first audio output module on after determining the angle is greater than the reference angle.
