20080316777 | Method for thermal protection of frequency converter and a frequency converter - A method for thermal protection of a frequency converter and a frequency converter that comprises means for controlling the output current of the frequency converter. The method comprises the steps of determining beforehand two or more data points which define a thermal current limit for a semiconductor component of the frequency converter at specific temperatures at two or more switching frequencies, determining beforehand two or more data points which define a thermal current limit for the semiconductor component at specific temperatures at a zero converter output frequency, measuring the temperature of the semiconductor component, determining the switching frequency of the frequency converter, determining the output frequency of the frequency converter, determining the highest allowable thermal current as a function of measured temperature, determined switching frequency and determined output frequency on the basis of the defined data points, and limiting the output current of the frequency converter to the determined highest allowable thermal current. | 12-25-2008 |

20100290408 | Method, apparatus and computer program for user equipment access channel procedures - Access to a wireless network is attempted by sending on a random access channel RACH at a first transmit power a first preamble comprising a signature sequence that is randomly selected from a set of signature sequences. After the access attempt from sending the first preamble is determined unsuccessful, access to the wireless network is re-attempted by sending on the RACH at a second transmit power a second preamble comprising a signature sequence, in which the second transmit power is no greater than the first transmit power. Embodiments variously combine different options: the signature sequences of the first and second preambles are each randomly selected separately, or the signature sequence of the first preamble is re-used in the second preamble; the first and second transmit powers are each equal to an initial transmit power, or the second transmit power is the initial power and less than the first transmit power. | 11-18-2010 |

20090106366 | SYSTEM AND METHOD FOR VISUALIZING THREADED COMMUNICATION ACROSS MULTIPLE COMMUNICATION CHANNELS USING A MOBILE WEB SERVER - A system, apparatus and method for visualizing threaded communication across multiple communication channels using a Mobile Web Server. A Mobile Web Server enables access to the messages received on a wireless communication device from the Internet using any web browser. Messages belonging to the same conversation, even if received on multiple communication channels (SMS, MMS, email, IM, Bluetooth, etc.), may be displayed in a threaded fashion. Once displayed on the web browser, a user may then view, create, edit, send, receive and filter the messages according to sender, receiver, time ranges, keyword/content, etc. A user does not have to be in physical possession of his or her wireless communication device to access received messages. Rather, one advantage of the invention is to allow a user to access messages on the wireless communication device where the user has forgotten the wireless communication device or spends most of his or her time in front of a personal computer in a location remote from the wireless communication device. | 04-23-2009 |

20100293182 | METHOD AND APPARATUS FOR VIEWING DOCUMENTS IN A DATABASE - An approach is provided for determining documents to display and includes extracting, from metadata in a first document, data that indicates a function and a filter for determining which documents in a database may be viewed to perform the function. It is determined whether the function is to be performed. If it is determined that the function is to be performed, then display of an icon representing a second document from the database is initiated based on the filter. In some embodiments, a document is transmitted, which includes metadata that comprises data that indicates a function and a filter for determining which documents in a database may be viewed to perform the function. A message is also transmitted comprising data that indicates a recipient has permission to perform the function. | 11-18-2010 |

20090234950 | Service discovery - The invention can be used for enabling service discovery. Service discovery can be enabled by requesting, by a first apparatus from a gateway entity, information on apparatuses capable of providing a predetermined service and being located in proximity of the first apparatus, receiving, by the first apparatus from the gateway entity, a predetermined resource identifier associated with a second apparatus capable of providing the predetermined service and being located in proximity of the first apparatus, the predetermined resource identifier being received as a response to the request, and sending, by the first apparatus, a resource request to the second apparatus using the predetermined resource identifier associated with the second apparatus. Service discovery can also be enabled by receiving, by a first apparatus, a resource request sent by a second apparatus using a predetermined resource identifier associated with a wireless service of the first apparatus, wherein the second apparatus is located in proximity of the first apparatus, determining whether the wireless service of the first apparatus is to be made available to the second apparatus, initiating the wireless service at the first apparatus in case it is determined, that the wireless service is to be made available to the second apparatus, creating a response to the resource request, inserting into the response a parameter required for establishing a connection to the wireless service of the first apparatus, and sending the response to the second apparatus. | 09-17-2009 |
