Abstract: A contact measurement probe for measuring a temperature of a substrate in a process environment includes a probe head having a contact surface made of a ceramic material or a polymeric material for contacting the substrate. The contact measurement probe eliminates electrical biasing effects in process environments that include an ion source, thereby providing greater accuracy and reproducibility in temperature measurement.

Abstract: Provided herein is a name service that includes published data that is associated with one or more duration entities and one or more modification entities, enabling the name service to more efficiently manage access to published data. To publish data, a publishing client transmits a publication request to a name service. The publication request may specify a modification entity and a duration entity. The name service creates at least one name entry that associates the published data with the modification entity and the duration entity. There are several requests to modify or depublish published data that a name service will honor only when they originate from a modification entity. These are (1) requests to modify published data, and (2) requests to depublish published data. A name service depublishes published data based on the termination of the duration entity that is associated with the published data, when, for example, a garbage collector detects that the duration of an entity has ended. Name service recovery is performed on a system failure. The remaining name service daemons delete each name entry that is non-local and non-persistant, and transmit requests to replicate local name entries to the other surviving name service daemons. A name service persistently stores name entries as specified. When restarted, the name service may continue to provide the persistently stored name entries. Persistent name entries are not depublished during name service recovery. They are explicitly modified or depublished by a modification entity.

Abstract: The effects of optical impairments on optical signal transmission are substantially reduced in a lightwave transmission system by positioning optical amplifiers and network elements in respective upstream-downstream combinations. By placing an optical amplifier at a position upstream from its corresponding network element, sufficient amplification can be provided by the optical amplifier to compensate for losses introduced by its corresponding network element. Advantageously, the corresponding downstream network element provides sufficient attenuation of the forward travelling lightwave signals so that power-dependent nonlinear effects in the optical fiber do not significantly distort the lightwave signals. Moreover, because of the downstream location of the network element in relation to its corresponding network element, the network element substantially suppresses backward travelling optical signal components such as those caused by Rayleigh backscattering, Stimulated Brillioun Scattering (SBS), and the like. As such, the network element prevents unwanted back reflections and back scattered signals from affecting operation of its corresponding optical amplifier.

Abstract: A method of modeling erbium doped fiber (“EDF”) for use in erbium doped fiber amplifiers (“EDFA”). The EDF has a length and a fractional population density of erbium ions in an excited state. Since the EDF supports N channels, the power propagation along the EDF is characterized by N+1 differential equations as a function of the direction of propagation, z, of the channels along the length l of the EDF and the time t. By applying an average inversion model to a spatially averaged inversion level of the erbium ions in the fiber, the N+1 partial differential equations are reduced to a single ordinary differential equation. This allows an analytical solution at the boundary and initial conditions of the fiber so that an expression for the power of the signal propagating along the fiber can be obtained. With this expression, the single equation can be solved analytically for the inversion level at any point along the EDF.

Abstract: A two-wavelength WDM analog CATV transmission system which utilizes wavelength channel spacing of about 2.2 nm and laser-dithering. The system includes a pair of optical transmitters (DBF lasers), a pair of modulators, a dithering device, a polarization controller, a 3-dB combiner, an optical amplifier (EDFA), an attenuator, a length of optical fiber, a filter and a CATV receiver. The two lasers have wavelengths of .lambda.1 and .lambda.2, where the difference between .lambda.1 and .lambda.2 is approximately 2.2 nm. The modulators are driven with analog signals comprising 77 NTSC channels between 55.25 and 535.25 MHz A 2-GHz dithering tone is applied to the .lambda.1 laser and the output of the .lambda.2 laser is passed through the polarization controller to align the polarization of the two transmitters. The two modulated and aligned outputs are combined by the 3-dB combiner and launched into the EDFA The output of the EDFA is divided by the splitter four ways and one of the four outputs is passed through the attenuator and launched into the transmitting end of the optical fiber. The receiving end of the fiber is connected to a filter, which provides input into the CATV receiver. By utilizing a wavelength channel spacing of about 2.2 nm and dithering one of the lasers, worst-channel Composite Triple Beat distortion is reduced to -60 dBc, an acceptable level for deployment of WDM analog CATV systems.

Abstract: Disclosed is a method and a system for using techniques to stitch cybersecurity, generate network risks and predictive mitigations. The method includes collecting data from several data sources and labeling events. The method includes creating a profile for each entity observed in the data with the behavior of the profile determined through the analytical analysis of the events in which the entity participates including the transference of labels from events to the entity. One or more profiles of an organization are identified that have changed and the change is processed using specific attack sequence detection to identify one or more risks associated with each profile. The method further includes notifying one or more users associated with the one or more profiles based on the one or more risks.
