Title: Localized application of fine denier fibers onto a spunbonded web for optimization of leg cuff hydrophobicity in diapers and pads
Inventor: GRAY BRIAN F
IPC: A61F5/44
Filed: 1996-03-25
Granted: 2001-12-18
Abstract: A disposable absorbent article (26) that effectively prevents the leakage of  body fluids beyond its confines. The article of the present invention comprises a body (28) having a fluid-impermeable backsheet (34), an intermediate, fluid-absorbing core (32), and a fluid-permeable topsheet (30) . A pair of leg cuff assemblies (46, 46') is attached to the body. Each assemb ly comprises a cuff standing portion (48, 48') and a cuff base portion (50, 50' ). The assemblies are composed of two hydrophobic nonwoven layers. A first laye r (54, 54') is composed of a spunbonded web and a second layer (56, 56') is composed of a meltblown fiber. The first layer extends from the free, unattached end (58, 58') of the cuff standing portion (48) to the distal edg e (60, 60') of the article defining the leg opening. The second layer is provided where needed and in weights as needed to provide maximum assembly hydrophobicity with a minimum use of material. This construction allows the cuff assemblies to form fluid-impermeable dams which prevent passage of body  fluid beyond the article along its leg hole sides.

Abstract: A device which eliminates all RF ingress noise from entering the CATV network in the upstream communication path includes a shunt filter, a detector and a filter with a bandwidth equal to the bandwidth of the upstream communication path. The device monitors signals transmitted in the upstream bandwidth and detects when a valid upstream communication is being transmitted. Upon detection of this valid signal, the shunt filter is switched out of the upstream communication path to allow the valid transmission to be sent. When the end of the valid transmission is detected and a predetermined delay has lapsed, the shunt filter is switched to block all upstream transmissions in the upstream communication bandwidth.

Abstract: A method and system in a data processing system for resynchronizing a received data stream (58) with a master clock (72) having a master clock frequency, wherein the received data stream (58) is clocked with a received data clock (56) that is out of phase with the master clock (72) by an arbitrary number of degrees. The master clock (72) and the received data clock (56) are compared (120, 204) at a frequency of a resynchronization clock for a predetermined number of times to produce comparison results (208). The resynchronization clock frequency may be less than the frequency of the master clock. The comparison results are analyzed to produce a relative phase indicator (134).  In response to the relative phase indicator exceeding, or being less than, a phase shift threshold (136, 210), the received data stream is reclocked (144) at a rising (212) or falling edge (214) of the master clock (72) to produce a resynchronized data stream (88), wherein the resynchronized data stream (88) is synchronized with the master clock (72) and contains the data of the received data stream (58).

Title: Optical transceiver using common optical path for transmission and reception
Inventor: JAVITT JOEL I
IPC: H04B10/118
Filed: 1998-03-12
Granted: 2002-04-16
Abstract: An optical transceiver that is particularly adapted for free-space optical telecommunication uses the same optical path for received and transmitted light to a large extent to avoid duplication of optical elements. Received light is split so that different portions can be sent to physically spaced photodetectors, one of which is for detecting optically received information, and others of which are for detecting misalignment of the transceiver. In this way, the alignment detectors do not interfere with light reception by the information detector.

Abstract: A completely closed and reinforced box-like structure for forming a void area in a concrete formation is constructed of a flat sheet that is scored with a plurality of parallel crease lines and features a side edge reinforcing panel. The reinforcing panel has a plurality of slots thereon. A plurality of interior and end pieces are slit scored so that they may be folded to provide interior and end support units. The support units define a plurality of spaced apart partitions having a plurality of slots and flat support surfaces thereon. The structure is assembled by initially folding the side edge reinforcing panel into a position generally normal to the flat sheet to define a longitudinal rib. The support units are then attached to the longitudinal rib by registering the slots in the partitions in interlocking relationship with corresponding slots on the rib. The support units are then rolled over to fold remaining panels of the sheet along the crease lines in wrapping relation around the support units and thus, the flat support surfaces. As a result, an enclosure with an interior chamber is defined wherein each of the support partitions substantially fills the cross-sectional area of the interior chamber and the flat support surfaces abut the enclosure. A pair of end panels cover the enclosure end openings so that the box-like structure is completely closed.

Filed: 1998-02-06
Granted: 2006-08-22
Abstract: Vehicle arresting beds, for installation at the ends of aircarft runways, ar e effective to safely decelerate aircraft entering the bed. The arresting bed is assembled of a large number of blocks of cellular concrete (70) having predetermined compressive gradient strength, so that aircraft landing gear is subjected to drag forces effective to slow a variety of types of aircraft, while providing deceleration within a safe range of values. An arresting bed typically includes an entry region (5 2) of a depth increasing from 9 to 24 inches formed of blocks having a first compressive gradient strength. A second region (54), which ma y be tapered into the first region and increase in depth to 30 inches, is formed of blocks having a greater compressive gradient strengt h. An aircraft thus experiences increasing drag forces while it travels through the bed, to provide an arresting capability suitable for a variety of aircraft. A protective hardcoat layer (62) of cellular concrete of strength greater than the blocks overlays the blocks to enable service personnel to walk on the bed without damage. Arresting bed systems may be provided in alternative configurations, such as a bed formed of an aggregate including pieces of cellular concrete with or without interspersed pieces of other compressible material and covered by a hardcoat layer.

Title: High speed decoder and decoding method
Inventor: TOWNSHEND BRENT
IPC: H04Q11/00
Filed: 1995-12-04
Granted: 2002-04-02
Abstract: A new data communication system is described which enables data transmission over existing telephone lines at rates higher than possible with existing methods, including conventional modems.  By using a novel asymmetric configuration of the two communicator endpoints, the currently-accepted maximum theoretical limits on the data rate are no longer applicable.  One endpoint is connected directly to a digital telephone network, whereas the other endpoint uses a conventional telephone connection.  This reduces the transmission problem to compensation for a single telephone line interface and a single analog local loop.  Means of providing this compensation and the required clock synchronization were also created, enabling a practical implementation of the system.          The new system can achieve rates up to 64,000 bits-per-second and has broad utility in several  active areas including wide-band audio transmission, video transmission, networking, facsimile transmission,  and remote computer access.

Title: Loudspeaker array for enlarged sweet spot
Inventor: BAUCK JERALD L
IPC: H04R5/00
Filed: 1998-05-28
Granted: 2007-07-03
Abstract: The invention is a method of creating an enlarged listening sweet spot for multiloudspeaker audio reproduction. The method employs a plurality of audio drivers (52, 56) displaced generally in a horizontal dimension for a vertically oriented head of a listener (60), the drivers operating over a plurality of different passbands (42, 46). Higher frequency drivers (55, 59) are located closer to one another and displaced more towards a center line of the listening space than lower frequency drivers (53, 57), thereby causing a smaller change in acoustic ear signals for listeners (60) seated away from the designed-for listening position, but without causing increased low frequency signal capacity requirements for phantom images generally outside the array (50). Specially adapted signal processing accounting for the layout of the various drivers and their associated crossover networks (40) is employed to create desired audio images.
