Abstract: A portable electronic device is disclosed comprising data processing means and a data repository containing: data records representative of locations relevant to or within a digital map; and data representative of an index associating words contained in the data records with the records in which those words appear. The device further comprises means for, in relation to a received search query including a search string, processing the search string to provide one or more search words; querying the index to identify data records containing the or each search word; and generating a rank for each of the one or more identified data records indicative of the relevance of each identified data record to the search query.

Abstract: A portable electronic device is disclosed comprising: data processing means; data repository containing data representative of a digital map; and display means. The device further comprises means for, in relation to data representative of a plurality locations relevant to the digital map, providing, on a representation of the digital map displayed on the display, for each of the locations, one of a plurality of different graphical user interface (GUI) elements characterised by different prominence levels to indicate the locations, wherein the prominence level of the GUI element used for each location is dependent on the level of detail at which the digital map is displayed and a deemed relevance of that location to a user query.

Abstract: A portable electronic device is disclosed comprising: data processing means; data repository containing data records representative of locations relevant to or within a digital map; and display means. The device further comprises means for monitoring a free text search string as it is input by a user of the device; querying the data repository for matching records and generating suggestions selectable by a user to adjust the search, based on the search string as it is input; displaying at least some of any matching records and suggestions on the display; and, in response to receipt of user input indicating a selection of a matching suggestion, adjusting the search accordingly.

Abstract: The invention provides real time dynamic resource management to improve end-to-end QoS by mobile devices regularly updating a resource availability server (RAS) with resource update information. Examples of resource update information are device battery status, available memory, session bandwidth, delay, packet loss, and jitter, network element storage capacity, network element processing power. This information is made available by the RAS. In addition, the RAS generates and maintains predictive models and makes available predictive data from these models. Network elements and devices retrieve this information in the form of notifications from the RAS or by way of querying the RAS. The network elements and devices, based on these predictions, act to negotiate sessions to optimise QoS. In one embodiment the RAS is updated by only mobile devices subscribed to the operator which hosts the RAS. The update information is addressed to the RAS as a stand-alone entity.

Abstract: When a device is switched off, all messages for that device are stored in different distributed service centers. For example, the message from user A may be stored in SMSC A and a message from user B in SMSC B where both subscribers and respective SMSCs can even belong to different networks. When the device is switched on again it notifies its presence to the network (performed by the MSC indicating this to the HLR). As a result of this alert, different service centers that have messages pending for that device will be notified that the device has come on-line again (performed by the HLR notifying SMSC A and SMSC B). Instead of directly sending out all messages, as in the prior art, each service center instead schedules the messages in an internal queue for delivery according to a local control scheme, which achieves synchronized delivery from multiple distributed SMSCs even though there is no centralised control.

Abstract: Devices (1) comprising magneto resistive systems (2) for detecting incoming magnetic fields and comprising first/second branches with first/second magneto resistive elements (21-22) having first/second resistance values depending on the incoming magnetic fields according to first/second response curves are provided with shifting means for shifting the first/second response curves of the first/second branches into first/second directions to get an adapted linear behavior. The shifting means comprise first/second structures of the first/second branches resulting in a first/second local fields at the first/second branches such that the first/second response curves of the first/second branches are shifted into the first/second directions.
