摘要： A device for vaginal insertion that corrects the anatomical defect which is the cause of majority of prolapses is disclosed. Said device comprises a base member (or body), two lateral members (or opposite side arms) attached to two opposing sides of said base member, and a protruding member (or handle) attached to the mid-section of said base member. Two lateral arms re-approximate the detached endopelvic fascia to the pelvic side walls at the site of the Arcus Tendineus Levator Ani. In an embodiment, the base member is elongated or rectangularly shaped and/or is concaved toward the vaginal apex. In another embodiment, the base member reduces the prolapsed uterus. The protruding member extends outwardly from the base member to support the bladder neck, thereby improving urinary incontinence. The device is formed of a biocompatible, flexible material, e.g., medical grade silicone, so that it can be folded, for example at a mid-section for insertion.

摘要： A new hybrid audio decoder and a new hybrid audio encoder having block switching for speech signals and audio signals are provided. Currently, very low bitrate audio coding methods for speech and audio signals are proposed. These audio coding methods cause very long delays. Generally, in coding an audio signal, an algorithm delay tends to be long to achieve higher frequency resolution. In coding a speech signal, the delay needs to be reduced because the speech signal is used for telecommunication. To balance fine coding quality for speech and audio input signals with very low bitrate, a combination of a low delay filter bank like AAC-ELD and a CELP coding method is provided.
