  • Patent number: 9620976
    Abstract: A modular system of devices, in which a (master) device can be combined with one or more of other (slave) devices to transform to functional electronic devices having expanded functionalities and features in different form factors and/or platforms. The master device is docked to the slave device via a data/electrical interface, to transform the master device to the larger form factor of the slave device, with the master device maintaining control of the slave device, substantially based on the operating system installed in the master device, with access to the data, application programs, functionalities and features embodied in the master device. An intermediate removable physical interface adaptor (or docking adaptor) is provided to facilitate docking compatibility of the master device to the slave device. An enhanced charging and power management scheme is provided to optimize power management for the master device and the slave device.

  • Patent number: 9185339
    Abstract: Embodiments of the present invention provide an efficient and cost-effective implementation of a method and system for increasing the frame-display rate of a video display device. Video data is often input to a video-display device in a compressed form that includes encoded and compressed motion vectors. The motion vectors provide information about portions of successive video frames which change in relative position. The motion vectors are decompressed and decoded along with the frames. In certain embodiments of the present invention, a first frame and an accompanying motion-vector table are transmitted from a processing component to a timing-controller component of a video-display device, using which the timing-controller component can generate a second frame that is displayed following display of the first frame.

  • Patent number: 9047050
    Abstract: A modular system of devices, in which a (master) device can be combined with one or more of the other (slave) devices in the system to form a functional electronic device (e.g., handheld cellular phone, tablet computing device), having different functionalities and features in different form factors across various platforms. The master device provides control and/or stored data to operate the slave devices, to reduce redundancy between devices of various form factors and/or platforms, in a manner that provides additional or different functions and features in an optimized and/or enhanced manner as the form factor and/or platform changes from one to another. The master device is not functional independent without attachment to a slave device. The master device requires at least a peripheral component (e.g., a display module) provided by the slave device to become an overall functional unit.

  • Publication number: 20130016046
    Abstract: A control method and system of a touch panel are provided. In the present method, at least one active area on the touch panel is selected first, and the remaining area of the touch panel is defined as an inactive area of the touch panel. Then, the inactive area is disabled. Thereafter, a corresponding action is executed on an electronic device according to a touch operation performed on the at least one active area. As a result, the power consumption can be reduced by disabling the inactive area while the electronic device is controlled by the at least one active area of the touch panel.

  • Publication number: 20120170771
    Abstract: A system with an input amplifier to receive and amplify a first audio signal, an output amplifier to output an audio signal which includes at least one of the amplified first audio signal and a second audio signal, a controller to adjust the input amplifier to a first input amp gain and the output amplifier to a first output amp gain to provide an output signal including the first audio signal at a first output signal level. The controller is to adjust the output amplifier to a second output amp gain to provide an audio output including the second audio signal at a second output signal level and determine an output amp ratio by dividing the first output amp gain with the second output amp gain. The controller is to determine a target input amp gain by multiplying the first input amp gain by the output amp ratio and adjust the first input amp gain to the target input amp gain to provide an audio output including the first audio signal at a third output signal level.
