| 20090275302 | Lower power wake-up device - A circuit for producing a wake-up signal to control powering up an electronic system, has a frequency selective radio frequency (RF) amplifier circuit that amplifies signals within a predetermined frequency range and produces an amplified RF output signal. An RF detector detects the presence of amplified RF output at the output of the amplifier circuit and produces a signal W indicative of the instantaneous presence of the RF output signal. A threshold detector circuit determines if the amplified output signal has reached a predetermined threshold and produces an output signal T. A clock generates a clock signal having clock period in response to the threshold detector output signal T. A data decoder logic circuit turns off the clock in the absence of an RF output signal for a prescribed time period and decodes the RF detector output signal W into a stream of output signals. A serial comparator circuit compares a most recent stream of N output data signals from the data decoder logic circuit with a stored reference pattern, wherein when the most recent stream of N output logic signals from the data decoder logic circuit matches the stored synchronization pattern the serial comparator circuit generates a wake-up signal that enables power to the electronic system. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract. | 11-05-2009 |
| 20100005484 | Point of Deployment Module to Retrofit Upstream Transmission Capability to an Audiovisual Device - A point of deployment module includes a HOST-POD interface for connecting the point of deployment module to a digital audiovisual receiver. A first connector on the point of deployment module may receive a downstream signal from a service provider. A second connector on the point of deployment module may provide a signal to a tuner of the digital audiovisual receiver. An out of band transmitter in the point of deployment module provides an upstream signal to the service provider. A combiner may be coupled to the first connector, the second connector, and the out of band transmitter. The combiner may transfer the downstream signal from the first connector to the second connector and may transfer the upstream signal from the out of band transmitter to the first connector. The point of deployment module may include a receptacle for a second point of deployment module connected to the HOST-POD interface. | 01-07-2010 |

In one embodiment, the antenna comprises a film comprised of translucent material, wherein the film overlays at least a portion of a viewing area of the display device. The antenna may further include a conductive element for receiving one or more wireless signals, the conductive element embedded in the film within the viewing area of the display device, and a terminal configured to couple the conductive element to one or more terminals of the display device. | 03-18-2010 |
| 20100110011 | ELECTRONIC BOOK WITH ENHANCED FEATURES - An electronic book can transfer book files to other cooperating electronic books using peer-to-peer principles and/or using wireless broadcast transfer principles. The electronic book can also automatically reformat a book file into a native format used by the book without user interaction. Additional electronic book features are also disclosed. | 05-06-2010 |
| 20100129782 | ELECTRONIC BOOK WITH ENHANCED FEATURES - An electronic book with opposed displays facing each other on a foldable housing can present book text on each page in portrait mode. Upon receipt of a mode change signal caused by, for example, the user rotating the book 90°, the lower display can display an image of a keyboard and/or text in landscape mode while the upper display can present text in landscape mode. The keyboard image may be for a user-selected language. | 05-27-2010 |
| 20100178883 | System and Method for Power Control in MIMO Systems - The return channel in a multiple-input and multiple-output (MIMO) communication system is used to provide signal information on an individual-channel basis. In one embodiment, in a controlled factory environment, this information may be used to incrementing up or down the variable gain amplifier and/or the power amplifier of a MIMO transmitter and/or receiver so as to generate a default signal power offset to be used during normal operation. Thereafter, such signal information may similarly be provided via the return channel and used to further adjust the transmit parameters to account for location-specific signal conditions. | 07-15-2010 |
| 20100194985 | METHOD AND SYSTEM FOR DISPLAYING A WIRELESS CHANNEL SPACE ON A DISPLAY DEVICE - Embodiments of the present invention are directed to provide a method and system for the generation and display of a channel space state for a band of frequencies in a wireless display device. One novel method enables the display of a channel space state by continuously or repeatedly scanning, in a remote wireless transceiver, a channel space to determine a channel space state. The channel space state is communicated to the wireless display device. When interference for the channel used to transmit content to the wireless display device is detected during a scan, a graphical representation of the channel space state is displayed in the wireless display. | 08-05-2010 |
