20140295931 | THREE-DIMENSIONAL GESTURE RECOGNITION SYSTEM, CIRCUIT, AND METHOD FOR A TOUCH SCREEN - A touch controller is coupled to a touch screen and detects a first gesture at a first point on the touch screen. The first gesture includes physical contact of the touch screen by a user device at the first point. The touch controller detects a second gesture that is associated with movement of the user device from the first point to a second point on the touch screen. The second gesture includes detecting movement of the user device within a sensing range from the first point to the second point. The sensing range corresponds to an orthogonal distance from a surface of the touch screen. The touch controller detects a third gesture at the second touch point. The third gesture includes physical contact of the touch screen at the second touch point. Upon detecting the first, second and third gestures the touch controller performs a corresponding action. | 10-02-2014 |

20110025435 | COMPACT RF ISOLATION NETWORK FOR MULTI-PIN PACKAGED INTEGRATED CIRCUITS - Pins on an RFIC package carry RF signals between the package and a PCB. A first capacitor is coupled between a selected pin of the RFIC package near the pins carrying the RF signals and a radio-frequency ground on the PCB. A coupling between the RFIC package and the PCB is modeled, and includes modeling of the pins of interest and at least one parasitic element of the coupling. A capacitance of the first capacitor is selected based on the modeling to obtain desired performance at selected operational frequencies. A second capacitor may be coupled between the selected pin a radio frequency ground of the RFIC package. An inductor may be coupled in parallel across the first capacitor. | 02-03-2011 |
20100329321 | ELECTRONIC DEVICE FOR RECEIVING A RADIO-FREQUENCY SIGNAL - An electronic device includes an analog-to-digital converter adapted to receive a radio-frequency signal and adapted to provide therefrom a digital signal, wherein the radio-frequency signal may include an interference signal. The electronic device has a controller adapted to perform a digital measure on the digital signal and adapted to generate therefrom a selection signal having a first value indicating a non-interference condition in the radio-frequency signal and having a second value indicating an interference-condition in the radio-frequency signal. A selector is adapted to transmit the digital signal in case the selection signal has the first value and to transmit a signal replacing the digital signal in case the selection signal has the second value. | 12-30-2010 |
20100284408 | SYSTEM FOR RECEIVING TRANSPORT STREAMS - A system comprising first input means for receiving a transport stream from an external source, second input means for receiving an input from a memory, means for connecting the first and second input means to an interface which is arranged to provide an output stream to a decoder.

20100245367 | METHODS AND DEVICE FOR DISPLAY DEVICE IN-SYSTEM PROGRAMMING THROUGH DISPLAYABLE SIGNALS - Methods and device for in-system firmware update in an information output device are provided. In one aspect, a method of firmware update in a display device receives a set of data in an image format through a video signal input channel of an input port of the display device. The set of data is converted from the image format to an instruction set format that is different from the image format. A first set of instructions that is used to operate the display device is updated with the set of data in the instruction set format. | 09-30-2010 |
20090253384 | Dual Mode Radio Frequency Front End Circuit - A dual mode radio frequency (RF) front end circuit includes a first transformer for conversion between a balanced and an unbalanced RF signal and a second transformer for conversion between a balanced and an unbalanced RF signal. A first switch is configured to selectively electrically connect to one of the first transformer, the second transformer and an RF transmit port. A second switch is configured to selectively electrically connect the first switch and a filter to one of the input and the output port of an amplifier. The first switch is connected to the input port of the amplifier when the filter is connected to the output port of the amplifier, and the first switch is connected to the output port of the amplifier when the filter is connected to the input Port of the amplifier. The first and the second switch cooperatively selectively connect one of the first transformer, the second transformer and the RF transmit port to the amplifier and the filter. | 10-08-2009 |
20090251221 | Radio Frequency Front-End Circuit - A radio frequency (RF) front end circuit includes a transformer coupled to a switch. The transformer converts a balanced transmit signal to an unbalanced transmit signal and converts an unbalanced receive signal to a balanced receive signal. The switch is configured to operate in first and second states. In the first state, the switch receives the unbalanced transmit signal from the transformer and transfers the unbalanced transmit signal to an amplifier and receives an amplified transmit signal from the amplifier and transfers the amplified transmit signal to a band pass filter. In the second state, the switch receives a filtered receive signal from the band pass filter and transfers the filtered receive signal to the transformer. | 10-08-2009 |
