| 20100015956 | RATING OF MESSAGE CONTENT FOR CONTENT CONTROL IN WIRELESS DEVICES - Systems, methodologies, and devices are described that facilitate filtering content sent to a mobile device(s) by a content provider via a core network. A content provider can determine a content rating for content, and/or the core network and/or mobile device can determine or infer a content rating for unrated content from a content provider, based in part on predefined content rating criteria. A mobile device user can specify a desired content rating preference for the mobile device. A filter(s) respectively associated with the core network and/or mobile device can filter the content based in part on the content rating of the content and the content rating preference of the mobile device to which the content is being sent. Content that does not meet a content rating threshold can be filtered out and stored in a secure content folder accessible using a security code or discarded. | 01-21-2010 |

| 20110305345 | METHOD AND SYSTEM FOR A MULTI-MICROPHONE NOISE REDUCTION - A method for a multi microphone noise reduction in a complex noisy environment is proposed. A left and a right noise power spectral density for a left and a right noise input frame is estimated for computing a diffuse noise gain. A target speech power spectral density is extracted from the noise input frame. A directional noise gain is calculated from the target speech power spectral density and the noise power spectral density. The noisy input frame is filtered by Kalman filtering method. A Kalman based gain is generated from the Kalman filtered noisy frame and the noise power spectral density. A spectral enhancement gain is computed by combining the diffuse noise gain, the directional noise gain, and the Kalman based gain. The method reduces different combinations of diverse background noise and increases speech intelligibility, while guaranteeing to preserve the interaural cues of the target speech and directional background noises. | 12-15-2011 |

| 20100273443 | CONTEXT-BASED MESSAGING FOR WIRELESS COMMUNICATION - This disclosure describes techniques for providing a wireless communication device with context-based voicemail messaging. In reply to a call, a wireless communication device may select a message based on a context. As an example, a wireless communication system may detect a call directed to a wireless communication device from a caller, generate one of a plurality of reply messages for the caller based on a context of the wireless communication device derived from input information received by at least one input of the wireless communication device, and transmit the generated reply message to the caller. In some cases, the message may be selected based on both context and caller identity. In addition, the message may be selected based at least in part on analysis of a pattern of usage or user activity with respect to the wireless communication device. | 10-28-2010 |

| 20110081026 | SUPPRESSING NOISE IN AN AUDIO SIGNAL - An electronic device for suppressing noise in an audio signal is described. The electronic device includes a processor and instructions stored in memory. The electronic device receives an input audio signal and computes an overall noise estimate based on a stationary noise estimate, a non-stationary noise estimate and an excess noise estimate. The electronic device also computes an adaptive factor based on an input Signal-to-Noise Ratio (SNR) and one or more SNR limits. A set of gains is also computed using a spectral expansion gain function. The spectral expansion gain function is based on the overall noise estimate and the adaptive factor. The electronic device also applies the set of gains to the input audio signal to produce a noise-suppressed audio signal and provides the noise-suppressed audio signal. | 04-07-2011 |

| 20100147677 | DRUM DESIGN FOR WEB PROCESSING - A roll to roll system for depositing a material on a workpiece is provided. In one embodiment, the system includes a drum, which rotates about an axis that is transverse to a process direction, and a number of PVD deposition units. The drum further includes a peripheral surface that includes a groove having a recessed workpiece contact surface that is parallel to the axis and disposed between a first side wall and a second side wall. A portion of the recessed workpiece contact surface supports a section of the workpiece and the first and second side walls maintain the section of the workpiece on the portion of the recessed workpiece contact surface as the workpiece is moved along the process direction. The PVD deposition units are disposed across from some of the portion of the peripheral surface and continuously deposit the material across a width of some of the section of the workpiece. | 06-17-2010 |

| 20110261709 | METHOD AND APPARATUS FOR THE USE OF MULTIPLE-INPUT, MUTLIPLE OUTPUT (MIMO) SYSTEMS FOR MULTI-PACKET RECEPTION (MPR) - A method for multipacket communication in an asynchronous wireless system includes the steps of transmitting at least two packets of 2M digital signals from a plurality of transmitters without other transmission taking place within a predetermined number of symbol durations from each side of each packet. Each transmitter generates digital signals denoted as at least two super-symbols according to an Alamouti coding scheme corresponding to M symbols of first set of super-symbols in a first transmission interval and a second set of super-symbols in a second transmission interval. The received packets include inter-symbol interference of the super-symbols when imperfectly synchronized which expands the time interval of the received packets. A symmetric Alamouti structure for the received packets is generated by folding the expanded received signal on itself, multiplying by a factor of −1, and decoding using the Alamouti structure for the received packets at each antenna of the receiver. | 10-27-2011 |
