Title: Space truss dome
Inventor: RICHTER DONALD L
IPC: E04C3/00
Filed: 1993-09-09
Abstract: The basic shape of a large span dome (10) is defined by a primary network (20) of structural struts (15) which are so arranged between their junctions (16) that they fully triangulate the surface (13) of the dome. The struts throughout network have substantially uniform cross-sectional dimensions which are defined with reference to strut loads encountered at and near the perimeter (37) of the dome. The central portion of the network is strengthenedto withstand snap-through of the dome by a truss system (30) comprised of a secondary network (35) of truss members (33) which lie in a secondary surface (31) which is inside the dome and is spaced from the dome's triangulated surface. The primary (20) and secondary (35) networks are tied together by tie members (36) which extend between connections (34) of the truss members and the strut junctions (16) and which lie in the planes of webs (25) of respective struts. The assembly of the tie members to the strut junctions can be achieved by use of the same fasteners (26) which connect the struts to their junctions.

Abstract: An efficient packet transport system for mixed traffic in which a packet fragmentation protocol allows traffic of different classes to occupy a single physical link. In one embodiment, packet fragmentation gives delay sensitive traffic priority over non-sensitive traffic. This allows both traffic types to coexist on a single data link. The protocol eliminates software overheads associated with misordered packets and efficiently transports both cell and frame formatted data using encapsulation.

Filed: 1996-04-10
Abstract: A television  viewer  is  automatically  connected over  a telephone network  to  an  information  service associated with or related to the television program being  viewed.    A  control  unit  produces  a  control signal in response to a viewer actuated button.   Data encoded in a non-visual part of the television signal is  recovered  by  a  decoder.    An  automatic  dialer connects to the network and dials a telephone number in  response  to  the  viewer actuated  button  being pressed.     A  communication  control  system  relays information between the information service connected to over the telephone network and the viewer.   The communication between the information service and the viewer may be voice and/or data communication,  with text data being displayed on the viewer's TV screen and the viewer's command inputs being entered from the control unit.

Title: Method of forming molecularly oriented containers
Inventor: GITTNER FRANZ
IPC: B29C45/00
Filed: 1994-10-26
Abstract: The invention relates to a method and apparatus for forming molecularly oriented plastic containers from generally cylindrical, hollow preforms (10) with one open end (18) formed by injection molding from a partially crystalline, molecularly orientable plastic for subsequent stretch blow molding. Melted material is injected into a preform mold at a predetermined fill rate controlled to minimize molecular flow orientation and further controlled to minimize residual stress which both are otherwise developed during injection. The preform (10) is then reheated below the crystal melting point by radiant heat source to a temperature that intercrystalline structures are melted without melting the crystal neclei. To avoid so-called edge effects resulting from the geometry of the heating zone, the preform decreases in thickness at both (18,12) ends. The preform is then repidly transferred to the mold in which it is streched axially with a rod engaging its closed end and then rapidly quenched against a polished mold surface.

Title: Method and apparatus for encoding and decoding digital signals
Inventor: LEIB HARRY
IPC: H04L1/00
Filed: 1996-09-18
Abstract: A method of encoding a digital signal comprising a sequence of digital words, each comprising a first portion and a second portion, comprises the steps of successively encoding respective first portions using a trellis code to produce a corresponding sequence of trellis-encoded words, using each of the trellis-coded words to select one of a plurality of subcodes of a block code, and using the selected subcode to encode the corresponding second portion of the digital word corresponding sequentially to the trellis-coded word used to select the subcode, thereby providing a sequence of codewords corresponding to the sequence of digital words. After transmission and/or storage, a sequence of codeword vectors comprising the codewords and noise may be decoded by operating upon each of the sequence of codeword vectors using a decoder for each of the subcodes to produce, for each subcode, an estimated decoded second portion and ametric representing the likelihood that the estimated decoded second portion is correct, given that the assumed subcode is correct; using a trellis decoder, operating upon the sequence of likelihood metrics and the associated estimated second portions to provide a sequence of estimated first portions; and associating with each of the estimated first portions the corresponding estimated second portion, thereby providing a sequence of output digital words corresponding to the sequence of digital words originally encoded. The block code may comprise a Kerdock code, the subcodes being cosets of the Reed-Muller code. The decoder may then comprise a Fast Hadamard Transform unit and a Viterbi algorithm decoder.

Filed: 1995-09-14
Abstract: La présente invention concerne une lumière réalisée par serpentin (10) et destinée à un instrument chirurgical. Elle est fabriquée à partir d'un filament à enroulement hélicoïdal résultant d'un boudinage réalisé en appliquant différentes tensions de précontrainte en différents points (10a, 10b, 10c) du serpentin (10). Si la tension de précontrainte appliquée au filament pendant l'opération de boudinage est relativement élevée, le serpentin est relativement rigide. Si la tension de précontrainte appliquée pendant l'opération de boudinage est relativement basse, le serpentin est relativement souple. En jouant sur la tension de précontrainte appliquée au filament pendant l'opération de boudinage, on confère au serpentin des différences de rigidité et de souplesse se répartissant par zones. La variation de tension de précontrainte peut être progressive ou brutale, ces variations pouvant intervenir plusieurs fois le long du serpentin. L'invention concerne également des instruments chirurgicaux incorporant ce serpentin. Le serpentin est fait de préférence avec un fil d'acier inoxydable de type 304 d'un calibre approximatif de 0,021 pouces, le boudinage étant réalisé en utilisant des tensions de précontrainte allant de zéro à plusieurs livres.
