Title: Television system & encoding station and decoding station for it
Inventor: BORGERS STEPHANUS MARIA CHRIST
IPC: H04N7/30
Filed: 1988-03-10
Granted: 1997-01-08
Abstract: In a television system a digital picture signal is subjected to a transform coding for the purpose of bit rate reduction. In order to detect motion effects between the two fields of a picture, these fields are also examined in a motion detector 8310. If no motion is detected, intraframe transform is employed and if motion is detected intrafield transform is employed. Small motion effects can be eliminated by subjecting the picture signal to a median filtering before subjecting it to an intraframe transform.

Abstract: Determination of the effectiveness of endothelial cell seeding upon a vascular graft surface within the operating room environment would be desirable to maintain quality control in any clinical trial. In this study, five fluorescent stains, mithramycin, Hoechst 33342, sulfofluorescein diacetate, Nile red, and rhodamine 123 were evaluated for their ability to fluorescently label endothelial cells on graft material and subsequently allow determination of seeded cell number and cell spreading. Of these agents, rhodamine 123 produced the most desirable characteristics. It allowed excellent cell visualization after a 30 minute incubation. Unlike the other four stains, using rhodamine 123 caused the cellular cytoplasm to fluoresce bright orange at a 510 nm excitation wavelength while the underlying dacron or expanded polytetrafluoroethylene demonstrated minimal autofluorescence. No inhibitory effect on cell attachment to plastic or subsequent cell growth in culture was observed. This technique can be utilized in the operating room to visualize part or all of an endothelial cell-seeded graft and to permit a quantitative as well as qualitative evaluation of the seeding process.

Abstract: A pipe coupling having an elastomer sealing sleeve which is approximately C-shaped in cross-section has a cylindrical housing which is split in the longitudinal direction, and which defines inwardly bent end walls and can be constricted like a pipe clip by means of a closure having tensioning screws, in which arrangement the sleeve, which is enclosed at the end faces and at the circumference by the housing and by a metal insert sheet bridging the housing gap and is approximately C-shaped in cross-section, is compressed in the circumferential direction and is brought to bear against the pipes to be coupled. Sliding rings, which are compressible in the circumferential direction, are located between the end faces of the sleeve and the end walls of the housing. Upon assembly of the coupling, these sliding rings are brought to bear against the outer walls of the pipes and form a sliding seat with the latter. This leads to increased insensitivity to changes with regard to the relative position of the sealing parts and the parts to be sealed, as well as to further increases in the existing adaptability of the coupling to irregular pipes.

Abstract: The method includes the steps of forming a conductive layer 3 on a first insulating layer 2 to be contacted with a substrate 1 through a contact hole 10, forming a second insulating layer 4 on the conductive layer to a predetermined thickness, coating a SOG in a groove formed on the second insulating layer caused by the contact hole, hardening the SOG, forming a third insulating layer 5 on the SOG layer and exposed the second insulating layer to a predetermined thickness, flowing third insulating layer at the high temperature to be planarized, and forming a metal line 7 on third insulating layer, thereby increasing the tolerance to electromigration.
