The ring receptacle is positionable adjacent to the housing receptacle for defining a pin hole therebetween. The seal pin is loosely positionable in the pin hole whereby movement about the seal ring is accommodated while preventing rotation thereof.

Abstract: A miniature mass spectrometer that may be coupled to an atmospheric pressure ionisation source is described. Ions pass through a small orifice from a region at atmospheric pressure or low vacuum, and undergo efficient collisional cooling as they transit a very short, differentially pumped ion guide. A narrow beam of low energy ions is passed through a small aperture and into a separate chamber containing the mass analyser.

Abstract: A catheter includes a fluid network for cooling the ablation electrode, surrounding blood and tissue. The fluid network comprises a circumferential channel having an annular shape and fluidly coupled to at least one proximal longitudinal channel configured to conduct fluid along a proximal length of the catheter.

Abstract: Data from live events is incorporated into virtual simulations and games. The data may be obtained from various sensors and transferred over a network. However, should one of the participants be a threat, then portions of the virtual simulations and games may be disabled to protect the other participants.

Abstract: A microengineered multipole ion guide for use in miniature mass spectrometer systems is described. Exemplary methods of mounting rods in hexapole, octupole, and other multipole geometries are described. The rods forming the ion guide are supported by etched silicon structures provided on first and second substrates.

Abstract: Peer-to-peer networks may be established by considering various characteristics of the peers when clustering the peers within the network. The characteristics may include operational criteria such as the cost of data transfer by each peer, the type and status of power being supplied to each peer, and the bandwidth available to each peer. The peer-to-peer networks may be established by requiring credentials to gain access to the peer-to-peer network, where those credentials may be a network access identifier that has previously been used to gain access to an underlying data network of the peer-to-peer network. The operational criteria used to select peers for clustering may be stored and accessed through association to the credentials used to gain access to the peer-to-peer network.

Abstract: Methods, systems, and products are disclosed for enforcing a rate limit for data traffic. One method identifies a unidirectional stream of data packets flowing through a server to a downstream end user. The unidirectional stream is classified according to a rate class, with each rate class having an associated rate limit. Each rate limit specifies a maximum bit rate at which the unidirectional stream may flow. When the actual bit rate of the unidirectional stream exceeds the maximum bit rate permitted for the associated rate class, packets of data are discarded to reduce the bit rate.

Abstract: Methods and assays for identifying a compound that modulates a protein-protein interaction between a first and a second protein. The methods and assays require a protease that is attached to the second protein and a split and rearranged reporter activating protein that is attached to the first protein, wherein the reporter activating protein comprises a cleavage site for the protease that is interposed between two portions of the reporter activating protein and wherein the two portions of the reporter activating protein are in a rearranged order.

Abstract: A method of mounting rods in quadrupole, hexapole, octupole, and other multipole geometries is described. First and second dies are used to hold the rods in the required configuration with the plurality of rods extending through each of the two dies. A coupling arrangement is used to separate the first and second dies, and also prevents motion in the plane of the dies. The rods are seated and retained against individual supports and arranged circumferentially about an intended ion beam axis. The supports are desirably fabricated from silicon bonded to a glass substrate, a support for a first rod being electrically isolated from a support for a second adjacent rod.
