20110125767 | System and Methods for Updating User Profiles and Providing Selected Documents to Users - The present invention provides an improved recommender system. In some embodiments, the recommender system automatically builds a user profile for a user based solely on the action or actions the user takes with respect to certain documents and the contents of the documents. That is, the profile is based on implicit ratings. In addition to maintaining a user profile for each user, each document in a set of documents will have its own document profile, which is also referred to as a document vector. Advantageously, in some embodiments, the user profile will consist of the same attributes as the document vectors. This advantageous feature enables the recommender system to compare users and documents in order to generate recommendations. | 05-26-2011 |

In this way, privacy of the user rating information is maintained because the original user rating information will be unknown to a recommender module. | 09-27-2012 |
20130046761 | Method and Apparatus for Social Tagging of Media Files - Media tagging is significantly improved by fusing subjective, user-specific tags with collaborative, community based tags. Users share multimedia metadata tags in a network of users, to improve automatic tag generation for personal multimedia collections without compromising media privacy. In one method, a combined set of annotation tags is suggested to a user, for use in annotating a given media file. The combined set includes a first set drawn from a private, user-specific repository, and a second set drawn from a public, shared repository. In each case, determining which tags are suggested involves computing similarities between an attribute vector associated with the media file being tagged and attribute vectors associated with the tags. An attribute vector is a set of values representing given types of contextual metadata. The similarity determinations may be weighted according to user-specific and shared weights, and these weightings can be adapted to reflect user and community preferences. | 02-21-2013 |

The receiver system also comprises a compensation circuit which varies the level of the output signal of the component and a control loop which monitors the component and controls at least one attenuator to be active or inactive so that the level of the signal to the component is within the input range, and controls the compensation circuit to keep the output signal of the component constant. The control of the compensation circuit and attenuators between the component and said at least one attenuator is carried out in synchronicity with the propagation of the received signal through the attenuator chain from said at least one attenuator. | 09-19-2013 |
20130288623 | RECEIVER SYSTEM COMPRISING A MAIN RECEIVER AND AU AUXILIARY RECEIVER FOR CORRECTING IMPERFECTIONS IN THE MAIN RECEIVER - A receiver circuit comprising first and second receivers for demodulating first and second parts, respectively, of a received signal. The receiver circuit also comprises an adjustment circuit for adjusting the demodulated signal from the first receiver. The output signal from the adjustment circuit is used as output signal from the receiver circuit which also comprises an adjustment value circuit for determining an adjustment value for the adjustment circuit in adjusting the output signal from the first receiver. The adjustment value circuit receives the demodulated signal from the second receiver and the output signal from the adjustment circuit and uses differences between these input signals for forming said adjustment value. The first receiver and the second receiver have different transfer functions within one and the same frequency range. | 10-31-2013 |

20110059711 | WCDMA AGC RECEIVER SNR ADJUSTMENT AND SIGNALLING - The present invention relates to a method, an Automatic Gain Control control unit and a receiver for Noise change output signalling. It also relates to an Adjustment Unit, a receiver and a base band detector for adjustment of an Automatic Gain Control output signal on the basis of the Noise change output signalling. In a first step a receiver receives a communication input signal. In a second step at least one Automatic Gain Control attenuator or amplifier in the receiver attenuates the communication input signal. In a third step the receiver produces at least one AGC output signal. In a fourth step at least one AGC control unit in the receiver initiates a changed gain setting on the receiver, when the level of an AGC control unit input signal received by the unit has been below a first threshold level or above a second threshold level during a detection interval. | 03-10-2011 |

20110070856 | AGC LOW THRESHOLD SIGNAL LEVEL DETECTION - The invention provides a receiver comprising an input end, an Rx-chain with at least one regulating means and an output end. The receiver further comprises a feedback loop in the Rx-chain, said regulating means arranged for providing a higher or lower gain setting. The feedback loop comprises an AGC Multilevel threshold detector unit, AMU. The AMU comprises at least one Low Multilevel Threshold Detector, LMTD, and said LMTD comprises at least two threshold detectors, each detector having an associated low threshold level and detection interval, the length of the detection interval being shorter the lower the low threshold level is arranged to be set. The higher gain setting being arranged to be initiated through the feedback loop when the absolute level of an AGC input signal has been below at least one of the low threshold levels during the entire detection interval associated with that low threshold level. The invention also provides a communication system comprising the receiver, an AGC Multilevel threshold detector Unit (AMU) and a method to adjust the gain in a receiver. | 03-24-2011 |
