An electronic device and a method are adapted to identify window control commands in a multi-window system. The electronic device displays multiple windows each respectively having a title bar on a touch interface. The electronic device executes the method to identify a window control command according to a touch gesture from a movement of a touch point detected on the title bar of one of the windows. The user can easily touch the title bar to operate a certain window.

A method and a device of starting applications installed on a mobile operating system (OS) is performed by a mobile device for the mobile OS to flag any application installed on the mobile OS as a windowed application and display the application under a multi-window mode when the application is started. When multiple applications are simultaneously started, the mobile OS sequentially determines if each application is a windowed application. If positive, the application is displayed under the multi-window mode, and the size and location of the displayed window frame with the application running thereon are adjustable, rendering higher operational efficiency and convenience of software applications installed on a mobile OS.
摘要:
A device of promptly starting windowed applications installed on a mobile operating system (OS) provides a starting button on a mobile device running the mobile OS installed thereon to promptly start a windowed application menu. The windowed application menu can be used to add or remove applications installed on the mobile OS to be started under a windowed mode thereto or therefrom. When users press the starting button to open the windowed application menu and execute any application in the application menu, the selected application is displayed in the windowed mode. The windowed application menu includes, but is not limited to, default applications installed on the mobile OS. Execution of any third-party application under the windowed mode can be supported by the windowed application menu. Accordingly, the operational efficiency and convenience of the mobile OS can be enhanced.

A firmware-based mechanism for protecting against physical attacks on ROM areas holding Authenticated Variables. A first hash of contents of at least one Authenticated Variable is created by a computing device's UEFI-compliant firmware and stored in a non-volatile storage location. Subsequently a second hash of contents of the at least one Authenticated Variable is created by the firmware and compared by the firmware to the stored hash to identify unauthorized modifications of the at least one Authenticated Variable occurring after the creation of the first hash.

A scalable method of determining in a firmware environment if the rate of occurrence of a detectable specified type of system event that occurs to a system component or discrete functional unit, has met a criteria with respect to a pre-selected threshold. When the meeting of the threshold criteria is detected, a previously defined action associated with the threshold criteria for the particular event can be invoked by the firmware. Embodiments may establish a sliding time-window that includes a currently detected type of system event and extends back a set duration in the past. Any occurrences of the specified event taking place earlier than the established time-window may be discarded while occurrences of the events during the specified time-window are added together with the newly detected event and compared to a threshold value to see if the threshold criteria has been met.

A remote control system using a handheld electronic device to remotely control electrical appliances includes a handheld electronic device and a command conversion device. The handheld electronic device uses a command input device to generate operation information. A command recognizing module receives the operation information, and identifies the corresponding home appliance remote control code. A wireless emission module emits a home appliance remote control code, which is received by the command conversion device. The command conversion device determines the infrared execution command corresponding to the home appliance remote control code. The infrared execution command is emitted by the infrared emission module to remotely control home appliances with the infrared remote control function. The handheld electronic device is enabled to provide a variety of different operating modes without significantly increasing the cost of the entire system.
摘要:
A mechanism for making increased amounts of firmware available to a computer pre-boot is discussed. To increase the amount of firmware available pre-boot, a design decision is made during the build process as to which segments of the firmware need to be placed on the ROM part and which segments of the firmware can be located elsewhere. The segments of the firmware that are stored remotely from the ROM are referred to as “virtual ROM modules”. Each of the virtual ROM modules is assigned a generated unique identifier, and a “message digest” is constructed for each module using an algorithm such as MD5 or SHA-1. In the software build of the ROM image, the message digest-unique identifier pair created for each Virtual ROM module is used as a logical pointer for the virtual module. Additionally, a search path variable is placed into the ROM image in non-volatile storage. The search path provides for one or more locations in which to look for the Virtual ROM modules, and may be updated at a later point in time.

A mechanism for creating secure storage for firmware for a computing device. A designated secure storage area holding firmware that is executable prior to a loading of an operating system for the computing device is created during a build of a ROM image. The creating marks one or more files as requiring encrypted storage and the one or marked files are combined during the build into the designated secure storage area. The designated secure storage area is located outside the ROM image and includes, during the build of the ROM image, a reference to the designated secure storage area in a build of firmware placed in the ROM image. The reference includes a flag indicating a current encrypted status of the designated secure storage area.

A method for updating a keyboard controller in a notebook computer is introduced. The notebook computer has a keyboard controller which further includes a random access memory (RAM) and a read only memory (ROM). Firstly, the updating method has the keyboard controller receive a command for updating the firmware. Then, a keyboard status and a command byte of the keyboard controller are stored into the RAM. The method has the keyboard controller enter into an idle status and/oror proceed to update the ROM. Further, the method determines whether or not the ROM has been completely updated. If the ROM has not been completely updated, the method will wait until the ROM is completely updated. Otherwise, a shutdown identifier is set and the keyboard controller is reset. Thereby, the notebook computer system will not be shut down and the associated keyboard and mouse can still function after the firmware for the keyboard controller is updated under the Windows environment.
摘要:
Systems and methods for performing flash updates during runtime are discussed. More particularly, the amount of secure memory required to prevent tampering during the update process is limited by storing hashes of logical blocks of the update image in secure memory after initial validation while storing the update image in non-secure RAM or another non-secure memory location. Additionally, disruptions to the computing platform are limited by dividing the logical blocks into smaller progress units to minimize the amount of time spent in the secure operating environment performing the update.
