Appl. No.:

11/515338

International Classification:

A61F 6/06

US Classification:

128830000

Abstract:

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.

Abstract:

A filter limits the bandwidth of a caption video signal in a video disc player to minimize color beats when the caption signal is displayed along with a picture video signal on a television receiver. The filter delay, which would otherwise cause offset between the caption and an associated background signal used to enhance visibility of the caption, is compensated for by extending the time duration of each occurrence of the background signal by a multiple of the filter delay.

Abstract:

There is disclosed a digital conference bridge for a delta modulated switching system having information transmitted by delta modulation bits in M channels of a time division multiplex frame, where M is an integer greater than three. N conferees, where N is an integer greater than two but less than M, are interconnected by a time switch to enable a conference to take place among the conferees. N three stage shift registers are provided, one for the delta modulation bits of each of the conferees. N sequence detectors are coupled to an associated one of the shift registers to produce a binary 1 output when bits stored in the shift register are all binary 1 or all binary 0. N counters each have their count increased by the binary 1 output of an associated one of the sequence detectors. A count comparator is coupled in common to all the counters and produces a control signal indicating a new speaker for the counter having the largest count. A selection matrix is coupled to each shift register and responds to the control signal to couple the delta modulation data of the new speaker through a one stage memory to the time switch for distribution to all of the conferees.
