| 20080232209 | Method Of Controlling Power States In A Multimedia System - This invention relates to controlling the power states in a multimedia system comprising a multimedia connector box including a multimedia source interconnected to a transmitter module, and a multimedia device including a receiver module interconnected to a multimedia sink, wherein the transmitter and the vice via multimedia interfacing means. A signal detector detects the signal activity between the power sources of the multimedia system for determining the current power state of the power sources, and a power switching mechanism adapts the power states of the transmitter and receiving modules to the power states of the power sources. | 09-25-2008 |
| 20110007727 | METHOD FOR A WIRELESS PERSONAL AREA NETWORK - The present invention relates to a method for a first coordinator operating at a first channel frequency in a wireless personal area network (WPAN), the WPAN further comprising a second coordinator operating a second channel frequency, the method comprising the steps of transmitting a message at a plurality of channel frequencies including the second channel frequency, requesting the second coordinator to change from the second channel frequency to the first channel frequency, and communicating with the second coordinator using the first channel frequency. As discussed above, advantages with the present invention includes that no priority based mechanism is needed due to the fact that the coordinator that initiates (e.g. starts) communication-decides on used frequency. Furthermore, every coordinator is able to have the coordinator it wants to communicate with to change to its decided frequency. The present invention also relates to a corresponding method for a second coordinator, a first and a second coordinator, a system comprising at least a first and a second coordinator, and a corresponding computer program. | 01-13-2011 |

| 20090129451 | Data Transmission Rate Adaptation in a Wireless Communication System - A method for controlling a data transmission rate of at least one transceiver in a wireless system, the transceiver including a transmitter and a receiver, the method including the steps of: determining a signal quality characteristic corresponding to a signal received at the receiver by measuring a difference between one or more reference constellation points and one or more received constellation points, the signal quality characteristic representing an estimation of signal degradation through the wireless communication channel; and modifying a data transmission rate of the transmitter as a function of the signal quality characteristic. The step of modifying the data transmission rate of the transmitter includes: determining lower and upper threshold levels representing reference minimum and maximum signal quality characteristics, respectively, corresponding to the data transmission rate; measuring a signal quality characteristic of the received signal; determining whether the measured signal quality characteristic is within the lower and upper threshold levels; maintaining the data transmission rate when the measured signal quality characteristic is between the lower and upper threshold levels; and increasing the data transmission rate when the measured signal quality characteristic is less than one or more lower threshold levels associated with one or more corresponding higher data rates. | 05-21-2009 |

| 20110015919 | Displaying Original Text In A User Interface With Translated Text - Methods, systems, and apparatus, including computer program products, for user interaction with machine translation. A user interface for receiving requests to translate text and/or documents from a first language text to a second language text. The translated text and/or document is displayed such that the first language text corresponding to a selected portion of the second language text can be accessed and displayed in the same user interface. | 01-20-2011 |
