摘要:
Some embodiments provide methods for use in providing information. These methods comprise: capturing, with one or more cameras of a display device, video along a first direction; detecting an object of interest that is captured in the video; obtaining additional information corresponding to the object of interest; determining an orientation of a user relative to a display of the display device, where the display is oriented opposite to the first direction; determining portions of each of the video images to be displayed based on the determined orientation of the user such that the portions of the video images are configured to appear to the user as though the display device were not positioned between the user and the object of interest; and displaying the portions of video images as they are captured and simultaneously displaying the additional information in cooperation with the object of interest.

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.
摘要:
The frequency of a digital data signal, such as a digital video signal, is intentionally varied or hopped before being sent over a network. This frequency hopping may be performed in accordance with a frequency hopping pattern shared with only intended receivers. The digital data signal may be further intentionally pre-distorted in accordance with a pre-distortion pattern which is also shared with only intended receivers. The frequency hopping and/or the pre-distortion patterns may be used to vary the frequency and modulation, respectively, on a periodic basis, such as a symbol-by-symbol or packet-by-packet basis.

A circuit producing a wake-up signal with a frequency selective RF amplifier that produces an amplified RF output. An RF detector detects the RF output and produces a signal W indicative of the the RF output signal's presence. A threshold detector determines if the amplified output signal has reached a predetermined threshold and produces an output T. A clock signal is generated 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 time period and decodes the RF detector output W into a stream of output signals. A serial comparator compares a most recent stream of N output data from the data decoder logic with a stored reference to generate a wake-up signal that enables power to an electronic system. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

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.
摘要:
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.

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.
