20100233246 | ADHESIVE TISSUE REPAIR PATCH AND COLLAGEN SHEETS - The present invention relates generally to synthetic polymer compositions that form interpenetrating polymer networks. In a preferred embodiment, the compositions comprise two multifunctionally activated synthetic polymers, along with a tensile strength enhancer. Such compositions form matrices that exhibit superior cohesive strength and in many instances can serve as adequate replacements for surgical means of attaching tissues, such as sutures, sponges and medical staples. | 09-16-2010 |
20110159075 | COMPOSITIONS AND SYSTEMS FOR FORMING CROSSLINKED BIOMATERIALS AND METHODS OF PREPARATION AND USE - Crosslinkable compositions are provided that readily crosslink in situ to provide biocompatible, nonimmunogenic crosslinked materials that may be used as adhesive compositions. The compositions comprise collagen and a plurality of crosslinkable components having reactive functional groups thereon, with the functional groups selected so as to enable inter-reaction between the components, i.e., crosslinking. Methods for preparing and using the compositions are also provided. Exemplary uses include tissue augmentation, biologically active agent delivery, bioadhesion, prevention of adhesions following surgery or injury, and coating of surgically acceptable patches and solid implants, the latter including sutures. | 06-30-2011 |

20110196673 | CONCEALING LOST PACKETS IN A SUB-BAND CODING DECODER - An electronic device for reconstructing a lost packet in a Sub-Band Coding (SBC) decoder is described. The electronic device includes a processor and instructions stored in memory. The electronic device detects a lost packet, obtains a zero-input response of a synthesis filter bank and obtains a coarse pitch estimate. The electronic device also obtains a fine pitch estimate based on the zero-input response and the coarse pitch estimate. The electronic device selects a last pitch period based on the fine pitch estimate and uses samples from the last pitch period for the lost packet. | 08-11-2011 |
20110293103 | SYSTEMS, METHODS, DEVICES, APPARATUS, AND COMPUTER PROGRAM PRODUCTS FOR AUDIO EQUALIZATION - Methods and apparatus for generating an anti-noise signal and equalizing a reproduced audio signal (e.g., a far-end telephone signal) are described, wherein the generating and the equalizing are both based on information from an acoustic error signal. | 12-01-2011 |
20110294501 | CODEC DEPLOYMENT USING IN-BAND SIGNALS - After a call is established between two stations using a codec that has been negotiated during call setup, in-band signaling may be used between the two stations to change the codec that is to be used. The in-band signals are indicative that the station that is transmitting the in-band signals can operate with a second codec and are used to probe whether the receiving station can also operate with that second codec. If the receiving station detects and reacts to the in-band signals, then both stations change to communicate with the second codec. The second codec has compatible packet sizes of the deployed (originally negotiated) codec without any need of infrastructure upgrade and/or quality compromise to legacy phone users (i.e., stations that cannot operate with the second codec). | 12-01-2011 |
20120263317 | SYSTEMS, METHODS, APPARATUS, AND COMPUTER READABLE MEDIA FOR EQUALIZATION - Enhancement of audio quality (e.g., speech intelligibility) in a noisy environment, based on subband gain control using information from a noise reference, is described. | 10-18-2012 |
20130035105 | APPLICATION NOTIFICATION AND SERVICE SELECTION USING IN-BAND SIGNALS - In-band signaling may be used between two stations to determine the capabilities of the stations and/or send actionable information between the stations participating in the call. The in-band signals are indicative that the station that is transmitting the in-band signals can use in-band signals as a conduit to send and/or receive various types of information and are used to probe whether the receiving station can operate similarly. If the receiving station detects and reacts to the in-band signals, then both stations can pass control information and data as well as enhancements between each other, without any need of infrastructure upgrade and/or quality compromise to legacy phone users. Additionally or alternatively, out of band interfaces and watermarking may also be used. | 02-07-2013 |
