Automatic determination of access point content and services for short-range wireless terminals

Abstract: A method and an apparatus in a short range wireless communication stores a list of keywords and a type list of information indicative of content and services available at an Access Point. A user terminal creates and stores a similar list of keyword and types. The user requests the keyword and types from the Access Point. This list is transmitted to the user within the service discovery protocol during connection set-up. The user Keyword list and Types are matched to the Access point Keywords and Types list to determine if a session should be established or terminated. The Access point may also connect to the terminal to obtain a list of the terminal Keywords and Types to determine if content is available to push to the terminal.

Co-channel interference cancelling receiver for TDMA mobile systems

Abstract: A method for co-channel interference cancellation in TDMA mobile systems exploiting the characteristics of mobile channels is proposed. The independently fading multipath channels provide a distinct waveform coding on each of the co-channel signals, which is a basis for signal separation in receivers. This enables the use of joint detection methods in receivers provided that accurate channel estimates can be obtained for all the cochannels. A joint detection and channel estimation algorithm for multiple co-channel signals are derived. The performance of the receiver is verified by simulations with the GSM system assuming that the strongest interferer is cancelled.

The stanford mobile visual search data set

Abstract: We survey popular data sets used in computer vision literature and point out their limitations for mobile visual search applications. To overcome many of the limitations, we propose the Stanford Mobile Visual Search data set. The data set contains camera-phone images of products, CDs, books, outdoor landmarks, business cards, text documents, museum paintings and video clips. The data set has several key characteristics lacking in existing data sets: rigid objects, widely varying lighting conditions, perspective distortion, foreground and background clutter, realistic ground-truth reference data, and query data collected from heterogeneous low and high-end camera phones. We hope that the data set will help push research forward in the field of mobile visual search.

Method for compressing dictionary data

Abstract: The invention relates to pre-processing of a pronunciation dictionary for compression in a data processing device, the pronunciation dictionary comprising at least one entry, the entry comprising a sequence of character units and a sequence of phoneme units. According to one aspect of the invention the sequence of character units and the sequence of phoneme units are aligned using a statistical algorithm. The aligned sequence of character units and aligned sequence of phoneme units are interleaved by inserting each phoneme unit at a predetermined location relative to the corresponding character unit.

System, mobile station, method and computer program product for managing context-related information

Abstract: A mobile station for managing context-related information includes at least one sensor capable of measuring at least a portion of at least one condition of the mobile station. The mobile station also includes a context engine capable of storing context-related information based upon the portion of the condition(s), where the context engine is also capable of managing an exchange of the context-related information with at least one context consumer. The mobile station further includes a privacy engine, a script engine and a communication manager. The privacy engine can provide security and/or privacy to the exchange of the context-related information. The script engine can execute at least one context rule relating to at least a portion of the context-related information. And the communication manager can communicate with at least one context consumer external to the mobile station for the exchange of context-related information.
