Abstract: Interference from other wireless technology co-resident on a Bluetooth-capable device may render one or more Bluetooth frequencies unusable for a Bluetooth introduction sequence. In this case, one or more usable frequencies may be substituted for the one or more unusable frequencies to permit the introduction sequence to proceed. The one or more usable frequencies may be selected from a known set of usable frequencies in the current Bluetooth frequency train. Alternatively, a frequency re-mapping process may be used to select the one or more usable frequencies from the current Bluetooth frequency train.

Abstract: The methods and devices enable displaying image portions generated on a first computing device on a second computing device. A master helper app on the first device receives user content selections and computes bounding boxes on each. The master helper app may expand the system frame buffer to hold the selected content and cause the windows manager to direct applications to draw contents into the expanded frame buffer. The master helper app may invoke a slave helper app on the second device to receive the frame buffer contents. The slave helper app stores the received display data in a frame buffer so the image is displayed. Resizing, blending and partitioning processing of display content can be accomplished on either the first or second devices or on a third proxy device. Keystrokes on the second device can be translated into commands executed on the first device.

Abstract: A reduced complexity short range wireless communication system and method are described providing a very low complexity, low cost, and low power version of Bluetooth Wireless Technology. In one embodiment, the low complexity version relies upon mechanisms and procedures already present in existing standards, such as Version 1.2 of the Bluetooth Specification. In this embodiment, the inventive method and apparatus take advantage of essential mechanisms and procedures already present in the Bluetooth Specification, while eliminating the need for the parts of the Bluetooth Specification that are not required by very low complexity devices.

Abstract: A sensor is configured to determine at least one operating condition of a device and a selector is configured to select an audio coding process for the device, based on the operating condition. The operating condition may include remaining battery life of the device and/or ambient noise level. The selected audio coding process may consume less power than another possible audio coding process during audio processing. The audio may include voice and/or audio playback, e.g., music playback.

Abstract: An executable is downloaded to an audio output device over a communications link. The executable may configure the audio output device to decode audio encoded in a specified format. The executable may also or alternatively include other audio processing software. The audio may include voice and/or audio playback, e.g., music playback. The ability to download an audio executable allows dynamic provisioning of various decoding and/or audio process capabilities to an audio output device. This may eliminate the need to transcode digitized audio for playback at the audio output device, and may also allow the audio output device to decode multiple audio formats without having multiple audio decoders permanently residing within the audio output device.

Abstract: A system and method for classifying channels in a frequency hopping wireless communication system is provided. A data collection engine operates to obtain channel metrics indicating the level of interference for each channel used by the wireless communication system. A data analysis engine operates to provide a channel map for adaptive frequency hopping (AFH) and/or a channel map for channel avoidance. More specifically, the data analysis engine first operates to filter the channel metrics to remove channel metrics indicative of frequency hopping interference. Next, the channels are divided into a number of channel blocks each including at least two adjacent channels. For each channel block, the channel metrics of the channels within the channel block are combined to provide a metric sum. The data analysis engine then operates to classify each channel as usable or unusable based on the metric sums for each of the channel blocks.

Abstract: An authentication scheme is provided for securely establishing an association with a second device over a wireless communication link. A cryptographic key exchange is performed between a first device and a second device, wherein cryptographic information for the first and second device is obtained. The first and second devices may independently generate a confirmation value based on the cryptographic information. Each device may obtain a confirmation image based on their respective confirmation values. A confirmation image is uniquely associated with a confirmation value so that no two confirmation values can be associated with the same confirmation image. The images for both the first and second devices are provided to an operator for authentication. If the confirmation images are identical, an association between the first and second devices may be confirmed by the operator. Comparing confirmation images may increase the reliability of operator authentication and is more efficient than comparing values.
