摘要:
A thin film composition is made from silicon, an insulator such as alumina or silicon dioxide, and at least one additional material such as chromium, nickel, boron and/or carbon. These materials are combined to provide a thin film having a ρ of at least 0.02 Ω-cm (typically 0.02-1.0 Ω-cm), and a TCR of less than ±1000 ppm/° C. (typically less than ±300 ppm/° C.). A sheet resistance of at least 20 kΩ/□ may also be obtained. The resulting thin film is preferably at least 200 thick, to reduce surface scattering conduction currents.

摘要:
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.

A method for traffic engineering of connectionless virtual private network (VPN) services that includes receiving physical connectivity data for a connectionless VPN. The data includes service nodes and links between the service nodes. One or more of the service nodes are also edge nodes. Logical connectivity data for the edge nodes is received. A restricted topology is created in response to the physical connectivity data and to the logical connectivity data. The restricted topology includes a single path between each pair of the edge nodes and each path includes a plurality of the service nodes and one or more of the links. A bandwidth requirement for each link in the restricted topology is calculated. The bandwidth requirement is reserved on each link in the restricted topology. The method further comprises directing routing software to force a packet received from an edge node through one of the paths in the restricted topology.

Bandwidth of a subscriber line, such as a Digital Subscriber Line (DSL), that carries Voice over Internet Protocol (VoIP) telephone calls and Internet Protocol Television (IPTV) transmissions is allocated. A message is sent from a VoIP call processor that is associated with the subscriber line and a video server that is associated with the subscriber line, so as to allow a VoIP call to take place at a desired quality of service, notwithstanding concurrent transmission of IPTV to the subscriber line by the video server. The message may be sent by the VoIP call processor in response to initiating setup of a VoIP call for the subscriber line by the VoIP call processor.

Preblends and preblend systems can be produced for use in, amongst other things, sunscreen products. These preblend systems and preblends can have high pigment loads, generally low viscosity and a relatively high thixotropic index making it both easy to use and very stable. Finished products including preblends and preblend systems are also described.

A communication network includes a hosting server and a plurality of data processing systems and is operated by uploading a coordination module from one of the plurality of data processing systems to the hosting server. The game hosting server coordinates peer-to-peer communication sessions among a plurality of users associated with the plurality of data processing systems.

Traffic is admitted to a network that facilitates differentiated end-to-end data transport between a Network Service Provider (NSP) and/or an Application Service Provider (ASP) and a customer Premises Network (CPN) that includes Customer Premises Equipment (CPE) by obtaining from a user of the network policy information associated with services accessed through the network. Communication is established between a node in the network and the NSP and/or the ASP and between the node in the network and the CPN using a resource reservation protocol (RSVP) to request resources for a flow having one of the services associated therewith between the NSP and/or the ASP and the CPN. A determination is made at the node in the network whether to grant or deny access to the RAN to the flow based on the policy associated with the one of the services.

A method and apparatus for optically interrogating a particle comprising obtaining a plurality of optical interrogations from a plurality of orientations relative the particle. In one aspect, the particle is tumbled relative to optical interrogation direction and reflected or transmitted energy is collected and added into a single spectrum that represents a complete spectral composition of the sample.
