Abstract: A network management apparatus and method for determining the topology of a network 1 is described. The present invention uses data relating to discovered devices on the network 1, typically network management address table data, to build a network tree. Due to the presence of unsupported or unmanaged connecting network devices, some branches of the resulting tree may not be resolved. In order to address this, for each unresolved branch of the network tree, the present invention attempts to determine the type of each of the discovered network devices on the branch, and if the type of every discovered network device on the branch is determined to be an endstation type, the present invention determines that an undiscovered connecting device is present on the branch.

Abstract: Embodiments of the present invention relates to an integrated mixer. A problem with producing low power consumption mixers is that they require a relatively high operating voltage due to the number of layers of transistor between the power rails.

Abstract: A process is described for the production of propane-1,3-diol. The process comprises subjecting a vaporous feed mixture comprising a hydrogen-containing gas and a feedstock selected from 3-hydroxypropanal, ?-propiolactone, oligomers of ?-propiolactone, esters of 3-hydroxypropanoic acid, and mixtures of two or more thereof to hydrogenation conditions in a hydrogenation zone in the presence of a heterogeneous hydrogenation catalyst, and recovering a reaction product comprising propane-1,3-diol.

Abstract: A technique for discovering the topology of a computer network and which relies on initially resolving the positions of end stations on the network and subsequently resolving the topology of remaining devices. This technique specifically involves querying a port of a managed device for a first address of any packet which it received; querying the same port for a second address of any other packet which the device received; if there is no such second packet, then returning data to a manager and determining if there is another port on the device; if there is such a second address, determining if there is another port on the device; repeating the preceding steps for the other port of the device; and if no such other port exists, repeating all the preceding steps for another managed device on the network.

Abstract: In a computer network, a process for discovering devices in the network, including network phones, and constructing a topological map of the network; and associated apparatus for retrieving an icon relating to the phones and displaying the map including the phones therein.

Abstract: An inspection system including a radio frequency (RF) subsystem and a quadrupole resonance (QR) tube array coil. The RF subsystem may include a variable frequency RF source to provide RF excitation signals at a frequency generally corresponding to predetermined, characteristic QR frequencies of a specimen. The QR tube array coil may be implemented using a plurality of conductive tubes defining a cavity of predetermined volume. Typically, the plurality of conductive tubes are spaced at a distance relative to one another to form at least two non-conductive gaps between tubes in the array. After RF excitation signals are applied to the specimen within the cavity, the QR tube array coil may generate a QR output signal responsive to QR signals generated by the specimen.

The oscillator uses a plurality of MOS varactors to, firstly, select the centre frequency of oscillation of the modulator and, secondly, to control the degree of modulation of that frequency.

Abstract: The present invention relates to a process for recovery of homogeneous metal hydride catalyst from a reactor stream as catalyst suitable for recycle to a reactor comprising the steps of: removing a stream from a reactor, said stream comprising the homogeneous metal hydride catalyst; contacting the stream with a solid acidic absorbent under process conditions which allow at least some of the metal to become bound to the absorbent; subjecting the metal bound to the absorbent, under process conditions which allow desorption of the metal, to a fluid stripping medium comprising hydrogen and solvent; and recovering the active metal hydride catalyst.

Abstract: The present invention relates generally to a method for the in vitro or in vivo production, by a eukaryotic host cell, of a protein from a negative sense single stranded RNA virus and, more particularly, to a method for the in vitro or in vivo production by a eukaryotic host cell of a protein from a virus of the family Paramyxoviradae and agents identified thereby. Still more particularly, said protein is the F, N, P or SH protein, the encoding nucleic acid molecule of which has been optimised for expression in a eukaryotic host cell. In yet another aspect, the present invention relates to a method for modulating the functional activity of an F protein. More particularly, said modulation is predicated on modulation of the functioning of a novel intrasequence cleavage event.

Abstract: In a computer network, a method to graphically distinguish on a network map a path between two points on a network. This is particularly useful in diagnosing problems, by tracing a path between two devices. While path tracing may be a relatively simple matter where there are relatively few devices, in a complex network, the paths between two devices will not be immediately obvious and indeed it is desirable to be able to ascertain whether there is more than one such path. There is disclosed a method for selecting a path or paths between two selected points in a network, said network comprising a plurality of points interconnected by links, comprising the steps of deleting from the method all points other than the selected two points having a single link to the remainder of the network to produce a reduced network, and repeating the deletion step until there are no points, other than the two selected points, which are connected to the remaining network by a single link.

Abstract: An object detection portal wherein a video image is obtained of a volume or area being scanned, and location of a threat object is determined and displayed in real time as an indicator overlay on the video image. An individual subject being scanned may be continuously monitored by an operator during an object divesting process, and an operator may view the threat object moving from or remaining with the subject. Object location information is supplied to a video driver to superimpose the overlay on a real time image of a subject. The scanning portal may interact with an exit barrier. The exit barrier may be activated automatically in response to sensing of a threat.
