In at least one embodiment, an apparatus is provided. The apparatus includes a measurement circuit, a trigger determination circuit, and a latch circuit. The measurement circuit is configured to receive an input signal from a transmitting source and to provide an averaged input signal based on the input signal. The trigger determination circuit is configured to receive the averaged input signal and to compare the averaged input signal to a predetermined threshold. The trigger determination circuit is further configured to provide a first output indicative of the averaged input signal exceeding the predetermined threshold. The latch circuit is configured to receive the first output and to trigger a latch condition to prevent the transmitting source from transmitting the input signal in response to the first output.

Infrared emitter checking circuit and method

A communication device performs a method for detecting presence of a jamming signal. The method includes retrieving a scan list comprising multiple radio channels within a first frequency range of operation of the communication device. The method further includes scanning at least a subset of the channels on the scan list to determine, for each scanned channel, whether energy that exceeds an energy threshold is detected on the scanned channel. Moreover, the method includes determining a first quantitative measure based on a first plurality scanned channels having energy that exceeds the energy threshold, and comparing the first quantitative measure to at least a first jamming signal detection threshold. Additionally, the method includes indicating, on the communication device, presence of a jamming signal when the first quantitative measure satisfies the at least a first jamming signal detection threshold.

A method and apparatus for choosing members of a local-area network and choosing a network coordinator among the members is provided herein. During operation a mobile node will determine presence information for nodes within its local area. These nodes will be solicited by the node to be part of a local-area network. Of all nodes that accept the request to form a local area network, a network coordinator for the local-area network will be chosen by determining which node's data budget allows for the cheapest transfer of data. The node with the best data budget is then chosen to be a network coordinator.

Link sharing within a communication system

A method and system that mitigates data session degradation over a radio link connection with an end server by allocating resources at a wireless communication device based on real-time radio frequency (RF) channel conditions. A performance tracking and resource allocation (PTRA) logic monitors radio access bearer (RAB) configuration and radio link quality for communication links between the WCD and the end server. The PTRA logic sets a maximum transmission unit (MTU) size parameter to a pre-established size associated with the measured radio link quality. In response to detecting a change in the RAB configuration, the PTRA logic performs a real-time round trip time (RTT) measurement utilizing individual RTTs associated with packet segments transmitted at a lower protocol layer. In addition, the PTRA logic modifies at least one of a transmission control protocol (TCP) receive window (RWIN) and a TCP transmit window (TWIN) using the real-time RTT measurements and RAB configuration.

Various embodiments of methods and apparatus' for compensating for a phase shift on a communication device are described herein. In an embodiment, an antenna of a communication device is tuned based on a characteristic of the communication device, thereby causing a phase shift of a signal that is to be transmitted via the antenna. A property of the signal at the antenna after the phase shift is measured. The phase shift is compensated for based on the measured property.

A method and apparatus for obtaining overhead information by a mobile is provided herein. During operation, the mobile will be communicating with a first system on an active data channel. The mobile node will be able to measure pilot PN phase and amplitude for a second system that is a potential candidate to handoff and will have that information available. The data channel of the active service is used to query a proxy server that provides overhead information for the second base station. More particularly, when PN phase and amplitude information is provided to the proxy server, the proxy server will identify the base station and provide the overhead information needed to associate with the second base station.

Disclosed is a display system and a method of a display system including a display device configured to provide visual output in a direction, and a camera associated with the display, the camera image collector being pointed in the direction of the visual output, the camera configured to collect facial data. A processor is provided to correlate facial data with content data so that the display will display specific content while the camera collects the facial data. A user's mobile communication device can detect the display system and transmit facial data to the display system. When a user is positioned so that the camera of the system can collect facial data of the user's face, the system can push specific content based upon facial recognition of the user correlated with the user's preferences or other criteria. A determination as to content to display is based upon facial recognition.

An electronic device is operable to display images on a display screen of the device's display. The images include at least one icon and at least one image to be used as a background setting for the display screen. The electronic device includes the display, at least one storage device, and a processing unit. The storage device(s) digitally stores the images and operating instructions for displaying the images. The processing device is operable in accordance with the operating instructions to: retrieve the images from the storage device, determine at least one portion of the background setting that is of higher importance than a remainder of the background setting to produce at least one high importance portion of the background setting, and instruct the display to display the background setting and the icons on the display screen such that the high importance portion(s) of the background setting is viewable.

A method and apparatus for performing the method are provided. The method includes operating a mobile device in a first network while a timer of the mobile device is running to prevent the mobile device from scanning for a second network. The method also includes determining a distance that the mobile device is from a reference location, where the reference location is associated with where the mobile device is prevented from scanning for the second network. The method further includes adjusting the timer when the determined distance from the reference signal exceeds a threshold. When the determined distance exceeds the determined distance, the mobile device can scan for the second network.
