Title: Multiplex wiring system
Inventor: VOLK JACK R
IPC: H04L1/22
Filed: 1988-06-15
Granted: 1991-11-05
Abstract: Abstract of the Disclosure A multiplex wiring system having a plurality of communication modules which are interconnected on a pair of buses.  Data is transmitted from any one of the modules on one of the buses while redundant or complementary data is transmitted on the other bus.  Each module includes three receiving channels, one channel for receiving data, one channel for receiving complementary data, and a differential channel for differentially combining the data and complementary data thereby reducing received noise.  A predetermined data sequence is detected on each of the three channels such that specific types of system faults are indicated.  In response to the fault indication, the most suitable of the three channels is selected to receive data.

Title: System integrated fault-tree analysis methods (siftan)
Inventor: RUTENBERG MARK R
IPC: G06F11/00
Filed: 1988-09-30
Granted: 1992-07-28
Abstract: Abstract of the Disclosure The subject invention employs a system integrated fault-tree  analysis  (SIFTAN)  which  has  the  unique  ability  to detect all  latent hardware and software design defects that could cause unanticipated critical failure of a complex software controlled electronic system.  This new approach modifies and then integrates   two   existing   system   analysis   techniques-namely, hardware  fault-tree  analysis  (HFTA)  and  software  fault-tree analysis (SFTA).  The resultant integrated technique is identified as SIFTAN for system integrated fault tree analysis.  Through its integrated hardware/software scope and its critical failure focus, SIFTAN  has  unique  potential  to  solve  the  essential  analytical limitation  behind the  software reliability problem.   The  system exceeds the scope of all  current  system  analysis  techniques by providing a system free from all potential critical specification hardware or software design errors.  The system accomplishes the above-noted objects by performing fault tree analysis with respect to the contents of a dynamic "stack of contradiction parameters" and then  superimposing the modified hardware  and software fault trees onto each other.  The super position is accomplished by automatically branching  from the  software  to  a  specified  fault tree hardware whenever hardware could result in a critical system output.   It  is  important  to  indicate that  the SIFTAN system is applied with great advantages to early conceptual levels of system design in addition to its certification of the final design implementation.

Title: Architecture and organization of a high performance metropolitan area telecommunications packet network
Inventor: HEMMADY JAYANT G
IPC: H04L12/56
Filed: 1988-11-16
Granted: 1992-12-01
Abstract: ARCHITECTURE AND ORGANIZATION OF A HIGH PERFORMANCE METROPOLITAN AREA TELECOMMUNICATIONS PACKET NETWORK Abstract A high capacity metropolitan area network (MAN) is described. Data traffic from users is connected to data concentrators at the edge of the network, and is transmitted over fiber optic data links to a hub where the data is switched. The hub includes a plurality of data switching modules, each having a control means, and each connected to a distributed control space division switch. Advantageously, the data switching modules, whose inputs are connected to the concentrators, perform all checking and routing functions, while the 1024x1024 maximum size space division switch, whose outputs are connected to the concentrators, provides a large fan-out distribution network for reaching many concentrators from each data switching module. Distributed control of the space division switch permits several million connection and disconnection actions to be performed each second, while the pipelined and parallel operation within the control means permits each of the 256 switching modules to process at least 50,000 transactions per second. The data switching modules chain groups of incoming packets destined for a common outlet of the space division switch so that only one connection in that switch is required for transmitting each group of chained packets from a data switching module to a concentrator. MAN provides security features including a port identification supplied by the data concentrators, and a check that each packet is from an authorized source user, transmitting on a port associated with that user, to an authorized destination user that is in the same group (virtual network) as the source user.

Granted: 1993-10-12
Abstract: ABSTRACT     A rotary pump mechanism is disclosed which comprises a coupling section that couples an impeller and means for driving said coupling section and, in turn, said impeller. The coupling section incorporates most of the components of the pump that wear out and are expensive. As a result, the impeller can be disposed of without disposing of other components. The coupling section can also be changed for continuous operation of a single impeller. Although the preferred application of the invention is in the area of pumping blood and other biological fluids, the disclosed invention has utility in any application where It is desirable to turn an "impeller-like" element.

Abstract: TITLE Pipe Joints ABSTRACT A pipe joint consists of a sleeve (2) surrounding a socket chamber  (3)  for  receiving  a spigot  (5).   A gland  (9) extends  into  the  socket  chamber  (3)  against  a  heel portion (12) of a sealing ring (7).  Axial movement of the gland (9) forces the sealing ring (7) and causes a leading nose portion (14) of the sealing ring (7) to be deflected radially inwardly by the internal profile of the sleeve (2) against the external surface of the spigot or pipe end (5), thereby forming a seal.  The heel portion (12) of the seal ring (7) maintains substantially the same radial position in the socket (3).

Abstract: An improved vector which upon introduction into a suitable host containing the thermolabile repressor CI renders the host capable of effecting expression of a desired gene. The vector is a double-stranded DNA molecule which includes in 5' to 3' order the following:  the promoter and operator P L O L from lambda bacteriophage; the N utilization site; a first restriction enzyme site which follows thereafter; a ribosomal binding site; an ATG initiation codon or DNA which is converted into an ATG initiation codon upon insertion of the desired gene into the vector; a second restriction enzme site for inserting the gene in phase with the ATG initiation codon; an origin of replication and either a gene associated with a selectable or identifiable phenotypic trait manifested when the vector is present in the host or a fragment designated cI434 which includes the gene for the cI434 repressor protein and its associated promoter and operator.  The distance between the 3' end of P L O L and the 5' end of the N utilization site is less than about 80 base pairs. The distance between the 3' end of the N utilization site and the 5' end of the ribosomal binding site is less than about 300 base pairs.  Vectors of the invention may also include a T1T2 rRNA transcription termination sequence located 3' of the second restriction enzyme site.  The inventive vectors may have origin of replications capable of autonomous production in the host of at least 400 constitutive copies.  Plasmids have been constructed from the vectors and used to produce bovine, chicken, porcine and human growth hormones, human apolipoprotein E and human superoxide dismutase and analogs thereof in host cells.
