Memory management method and system
Wireless headphones receive music and video from media devices via different wireless transmission methods such as using Bluetooth. However, wireless headphones suffer from limitations despite the convenience they offer to users. Some such wireless headphones allow one user to share the music experience by passing one side of the wireless headphone to a third party. The third party does not however get to experience and enjoy the full stereo experience of the music. In addition, sharing of music by transfer of media files from one storage medium to other storage medium often infringes upon third party intellectual property rights. An embodiment of the invention describes a method and a system that enable wireless sharing of audio sounds among a plurality of users. |

Value recycling facility for multithreaded computations
Solutions to a value recycling problem facilitate implementations of computer programs that may execute as multithreaded computations in multiprocessor computers, as well as implementations of related shared data structures. Some exploitations allow non-blocking, shared data structures to be implemented using standard dynamic allocation mechanisms (such as malloc and free). Some exploitations allow non-blocking, indeed even lock-free or wait-free, implementations of dynamic storage allocation for shared data structures. In some exploitations, our techniques provide a way to manage dynamically allocated memory in a non-blocking manner without depending on garbage collection. While exploitations of solutions to the value recycling problem that we propose include management of dynamic storage allocation wherein values managed and recycled tend to include values that encode pointers, they are not limited thereto. Indeed, the techniques are more generally applicable to management of values in a multithreaded computation. For example, value recycling techniques may be exploited, in some cases, apart from dynamic storage allocation, to allow a multithreaded computation to avoid the classic ABA hazard. |

Reinsurance participation plan
A reinsurance participation plan allows an insurance carrier to provide novel loss participation plans to insureds. The insurance carrier cedes a portion of the risk to a reinsurance company, such as a captive reinsurance company. The captive reinsurance carrier then enters into a contractual agreement with the insured for the participation plan, subject to the appropriate regulations for the primary line of insurance in question. The participation plan may be a non-linear participation plan, such as a curvilinear participation plan, where the non-linearities allow the plan to be offered to smaller companies than would otherwise qualify for more traditional retrospective participation plans, and to provide more advantageous plans to larger companies than they would otherwise be offered. The plans may be offered on a multi-year basis with particular diligence in informed consent for the prospective insured. Plans may be offered to small companies whose loss experience is aggregated and then divided according to relative premium amounts among the small companies such that the aggregate losses have a distribution with skewness comparable to that of a medium sized company. |

Method and apparatus for performing packet loss or frame erasure concealment
The invention concerns a method and apparatus for performing packet loss or Frame Erasure Concealment (FEC) for a speech coder that does not have a built-in or standard FEC process. A receiver with a decoder receives encoded frames of compressed speech information transmitted from an encoder. A lost frame detector at the receiver determines if an encoded frame has been lost or corrupted in transmission, or erased. If the encoded frame is not erased, the encoded frame is decoded by a decoder and a temporary memory is updated with the decoder's output. A predetermined delay period is applied and the audio frame is then output. If the lost frame detector determines that the encoded frame is erased, a FEC module applies a frame concealment process to the signal. The FEC processing produces natural sounding synthetic speech for the erased frames. |

Method and apparatus for measuring RTT in a cumulative acknowledgment transmission protocol
Round-trip time estimates may be calculated from an acknowledgement of an original packet transmission or from an acknowledgment of a retransmission without ambiguity by using different segment sizes for the same packet during transmission and retransmission. By using different segment sizes, the retransmitted segment will be acknowledged with a different acknowledgement number. In one embodiment, a TCP sender uses segment sizes that are slightly smaller than the maximum segment size for the initial transmission (e.g. MSS-4 bytes), and uses maximally sized segments during retransmission. When one of the two transmissions is explicitly acknowledged, the TCP sender can then use the different byte sequence acknowledgement numbers to discern which transmission is being acknowledged and correctly measure the round-trip time. This also allows the TCP sender to initiate the NewReno fast recovery algorithm only upon receipt of a retransmission acknowledgment. This is especially useful, for example, during periods of rapidly increasing delays caused by deteriorating network conditions or increased congestion. |

Technique for printing a color image
A technique for optimizing or enhancing color images. Embodiments are disclosed for creating an enhanced color image, including the enhancement of perceived color uniformity. In a “dot-on-dot” registration scheme for producing color images, the dots need to be precisely superimposed on each other to provide optimum or enhanced images. The dot-on-dot registration produced by a single head thermal printer is generally acceptable, but a single head machine is very slow because multiple passes (reciprocation) are required to lay down multiple colors of dots. In a much faster multi-head or tandem thermal imaging system a serious problem of dot misalignment may cause moire patterns or other visual artifacts in the color images produced by dot patterns. A solution to this problem is disclosed herein which intentionally misregisters superimposed dots in a novel and particular manner to achieve image optimization. In a particular embodiment a first thermal print head has a first number of thermal elements energized at a first rate and a second thermal print head has a second number of thermal elements energized at a second rate. The numbers of thermal elements and rates of energization are selected to cause intentional misregistration at a high spatial frequency which is unnoticeable to the naked eye of a viewer of the image, thereby masking any unintentional mechanical misalignment of the print heads while maintaining imperceptible the intentional misregistration of the solution to the problem. |
