Abstract: A method and apparatus for sharing product information amongst users of a computer network using productmarks. A productmark for a product is created by a user of the network and includes a product identifier, an annotation containing user comments, a username that identifies the creator of the productmark, and a categorization tag that identifies the user's level of interest in purchasing the product. Productmarks are stored in a database that may be queried using a product identifier, a username, a categorization tag or any combination of these to retrieve productmarks. A user network device provides access to the database and includes modules for creating and uploading productmarks to the database a module for querying and downloading productmarks from the database. A peer-to-peer communication session may be formed relating to a particular product and/or geographical location.

Abstract: There is disclosed a mobile device, and a method thereof, for creating media bookmarks. The mobile device comprises a user interface, a timing circuit, a processor, and a wireless transceiver. The user interface detects first and second user inputs associated with a media clip, in which the first user input precedes the second user input. The timing circuit provides a time stamp at a given time. The processor determines an end time associated with the media clip corresponding to a time stamp when the first user input is detected, and a start time associated with a media clip based on the second user input. The processor also identifies a broadcast channel associated with the media clip. The wireless transceiver transmits clip information based on the start and end times to a remote server via a wireless communication link.

Abstract: Various embodiments are described to address the need for reduced handoff delays associated with inter-AN (access network) HRPD (High Rate Packet Data)/1XEV-DO handoffs. The disclosed approach enables an AT (101) with an active packet data session to perform a hard handoff from a source AN (121, 221) to a target AN (122, 222) without having to force the data session dormant. Unlike known hard handoff approaches that involve coordination by a mobile switching center (MSC), the disclosed approach uses peer-to-peer signaling with no MSC involvement, such as that between source and target ANs or PCFs (131, 132, 231, 232). For example, data session information at the source side is transferred via new A13 messaging to the source entity's target-side peer to otherwise reduce signaling between the source and target equipment.

Abstract: Disclosed are methods and devices for controlling the state of a fan of an electronic device during audio output based in whole or in part on loudness data of a digital audio file. An audio data file is sampled so that loudness data is determined from the sample audio data. The loudness data may indicate at least one portion of the audio data file that has a predetermined loudness level. For example, when the loudness data indicates that the audio output is low, the fan can be deactivated or slowed. In this way the noise of the fan does not impair the user's audio experience. Alternatively, when the loudness data indicates that the audio output is high, the fan can be activated or its speed may be increased. The predetermined loudness level of the audio output may have a value that is sufficiently high to mask fan noise.

Abstract: A method for updating wireless application protocol (WAP) data at an electronic communication device during a mobile internet protocol (MIP) registration process includes processing at an authentication, authorization, and accounting (AAA) server a first access request message that identifies the electronic device (step 805). It is then determined that the electronic device requires updated WAP provisioning (step 810). The AAA server is then changed to a WAP provisioning ongoing state (step 815). An access reject message including updated WAP provisioning data is then transmitted from the AAA server (step 820). A second access request message, including the updated WAP provisioning data is then verified at the AAA server (step 830). The AAA server is then changed to a WAP provisioning valid state (step 835). Finally, an access accept message is transmitted from the AAA server (step 840).

Abstract: A mobile device estimates a data symbol from a received signal by using one or more interference cancellation algorithms. For one interference cancellation algorithm, the mobile device calculates a correction factor by estimating a Doppler speed and a time difference between a first time interval like a preamble symbol and a second time interval like any symbol of interest in an assigned data allocation in the data zone. Using the correction factor, the mobile device updates outdated interference information. The mobile device cancels interference in the received signal distorted by co-channel interference by using the updated interference information. Also, the mobile device is configured to combine results of multiple interference cancellation algorithms based on the applicability of the individual interference cancellation algorithms in particular scenarios.
