TL;DR: In this paper, a method and arrangement for creating a virtual keyboard for a terminal (800) used in a cellular network is described, where the virtual keyboard is generated using an IR transceiver arrangement in which a reflection from an obstacle placed in the field of IR transmitters is registered by discrete IR receivers.
Abstract: The invention relates to a method and arrangement for creating a virtual keyboard for a terminal (800) used in a cellular network. The virtual keyboard is generated using an IR transceiver arrangement (12) in which a reflection from an obstacle (15) placed in the field of IR transmitters is registered by discrete IR receivers. The received reflection data are processed in a neural network arrangement (33). The purpose of the data processing is to find out the virtual key position/function that the received reflection data corresponds to.

TL;DR: In this paper, a method and system for transmitting a transmission signal from an antenna array to a receiving means of a wireless communication system, wherein a signal quality measurement is performed at the receiving means (20) for predetermined antennas or beams of said antenna array (19) are selected.
Abstract: The present invention relates to a method and system for transmitting a transmission signal from an antenna array (19) to a receiving means (20) of a wireless communication system, wherein a signal quality measurement is performed at the receiving means (20) for predetermined antennas or beams of said antenna array (19). Based on a feedback information derived from the signal quality measurement, at least two of the predetermined antennas or beams of the antenna array (19) are selected. The selected antennas or beams are used for transmitting said transmission signal according to a transmit diversity or beamforming scheme. Thus, spectral efficiency and diversity gain can be enhanced by using only selected ones of the predetermined antennas or beams.

TL;DR: In this article, a method and apparatus for controlling access to stored personal data of a user is presented, where a user indicates which portions of personal data stored in a personal data repository are releasable to a second party.
Abstract: A method and apparatus are provided for controlling access to stored personal data of a user. A user indicates which portions of personal data of the user stored in a personal data repository are releasable to a second party. The user and the second party reach an agreement regarding use, by the second party, of any portions of the personal data in the personal data repository. The portions of the stored personal data in the personal data repository are released to the second party according to the agreement. The agreement includes what items within the personal data repository can be used by the second party. Only those items which, according to the agreement, can be used by the second party are released to the second party. In another embodiment of the invention, a method and apparatus are provided for selectively sending information. A trusted party device receives a request to send information. A user device is selected to receive the vendor information based on a willingness to receive the vendor information indicated within the stored personal data about the user. The vendor information is sent to the selected user device. Other aspects of the invention include a machine readable medium including instructions for a processor in a device to perform the methods described above.

TL;DR: The various evolution scenarios from the present 2G networks to 3G networks are discussed, and the UMTS QoS architecture and its requirements are presented, followed by a discussion on QoS in 3G air interfaces, radio access network, and core network.
Abstract: The third generation networks and services present opportunities to offer multimedia applications and services that meet end-to-end quality of service requirements. The key parts of the standards are already in place, and limited 3G services have already been turned on. While the evolution to 3G occurs, many operators will implement 2.5G interim solutions for a good period of time. We discuss the various evolution scenarios from the present 2G networks to 3G networks. Then we present the UMTS QoS architecture and its requirements, followed by a discussion on QoS in 3G air interfaces, radio access network, and core network.

TL;DR: E-SmallTalker is a distributed mobile communications system that facilitates social networking in physical proximity that automatically discovers and suggests topics such as common interests for more significant conversations and proposes a novel iterative Bloom filter protocol that encodes topics to fit in SDP attributes and achieves a low false positive rate.
Abstract: Small talk is an important social lubricant that helps people, especially strangers, initiate conversations and make friends with each other in physical proximity. However, due to difficulties in quickly identifying significant topics of common interest, real-world small talk tends to be superficial. The mass popularity of mobile phones can help improve the effectiveness of small talk. In this paper, we present E-SmallTalker, a distributed mobile communications system that facilitates social networking in physical proximity. It automatically discovers and suggests topics such as common interests for more significant conversations. We build on Bluetooth Service Discovery Protocol (SDP) to exchange potential topics by customizing service attributes to publish nonservice-related information without establishing a connection. We propose a novel iterative Bloom filter (IBF) protocol that encodes topics to fit in SDP attributes and achieves a low false positive rate. We have implemented the system in Java ME for ease of deployment. Our experiments on real-world phones show that it is efficient enough at the system level to facilitate social interactions among strangers in physical proximity. To the best of our knowledge, E-SmallTalker is the first distributed mobile system to achieve the same purpose.
