Abstract: A method for attaching a first surface to a second surface with a fastening device. The fastening device has a female component having a female opening featuring a broader female width at a first depth and a narrower female width at a second depth. The female component also has a female attachment surface with an interior slope rising away from the female opening. The fastening device also has a male component with a male attachment member that at least partially conforms to the interior slope of the female attachment surface. The male attachment member also has a broader male width larger than the narrower female width. The method comprises mounting the female component to the first surface, mounting the male component to the second surface, aligning the male component to the interior slope on the female component and applying pressure to couple the male component and the female component.

Abstract: A display device is provided comprising a housing, a communication means within the housing configured to receive content from a local content source device external to the housing and to transmit messages to the local content source device, wherein the content comprises a static screen image, a storage means configured to store the content having been received from the content source device, wherein the storage means stores no more than a single static screen image and a display configured to display the content. A method for use with the display device is further provided.

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.

Abstract: Methods for effecting transmitter and receiver synchronization are disclosed. A method includes reading an authentication key value that is calculated by a receiver that is to receive protected content from a transmitter, determining if there has been a change in the authentication key value calculated by the receiver since it was last read and determining if a counter associated with the transmitter has a zero value. A re-authentication of the receiver is initiated if the counter associated with the transmitter has a non zero value and the authentication key value that is calculated from the receiver has changed.

Abstract: Methods and apparatus for optical wireless communication. In one embodiment, a wireless optical video system in which video content (e.g., DVI or HDMI) is transmitted wirelessly between a digital video source and a display device. This wireless optical communication is accomplished using a laser, encoded with the digital video data, directed from an optical transmitter to an optical receiver. In another embodiment, the data to be communicated includes high-definition video content.

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.

Abstract: A quantized channel rate and corresponding rate multiplier is determined on a transmitter-side of a communication system based on a measured minimum required bandwidth. In certain embodiments, the quantized data rate may be an integer multiple of the system's reference clock. The determined rate multiplier is then transmitted to the receiver-side at a default data rate prior to or near the beginning of a data transmission session, such as upon initialization. Prior to transmission, the data stream may be padded with some determined amount of null data such that the actual transmitted data rate is approximately equal to the quantized channel rate, and the receiver-side can readily recover the data clock using its known reference clock and the previously-provided rate multiplier.

Abstract: A method and structure that supports the formation of co-linear device pairs and mitigation of undesired interference in a digital multi-media communication environment. Compass orientation information of co-located devices within range of one another in a wireless communication environment is used to determine whether sufficiently co-linear device pairing opportunities exist and may also be used to identify and/or mitigate undesired interference conditions. Various remedial actions may be performed to enhance co-linear device pairing and mitigation action may be taken to mitigation interference between substantially co-linear and co-located devices in the environment.
