Method and system for efficient routing of customer and contact e-mail messages
After a client or potential client accesses the web-site of a host organization and generates an e-mail to the organization, an e-mail sorting and routing system parses the meta-tags appended to the message to appropriately sort and route the message. The meta-tags specify the language of the client, i.e., the language in which the web-site was communicating with the client when the message was generated. The meta-tags also specify the topic, e.g. a product or service, about which the message was written. This information may be input by the client or ascertained from the content or purpose of the web-page from which the e-mail was generated. The messages are then sorted, first by language and then by topic. As a result, each message is quickly routed to a person qualified as to both language and subject matter who can respond to the client.
Routing client requests to back-end servers
Methods and computer program products for using a front-end server to access content stored on one or more back-end servers. The front-end server receives requests for content from client systems. Back-end servers store the content, but to the client system, it appears as if the front-end server is the content's source. Upon receiving the request, the front-end server checks the validity of the request and examines a global catalog that dynamically maps client system requests to the back-end server or servers that store the requested content. In some circumstances, the content will be stored at a single back-end server and the front-end server directs the request to that server. Alternatively, a list of back-end servers storing the requested content may be generated. If so, the front-end then uses an authentication token as a key to a hash operation that is performed on the list and a single server that is capable of satisfying the request for content is identified. A given request and authentication token always identify the same server if the list of servers available for providing the requested content remains the same. The front-end server provides a single source for content requests so that client systems are not required to alter requests or invalidate local caches when content is moved from one back-end server to another. The front-end server also provides an additional level of security for back-end servers.

Then, the event is transmitted and the subject is provided on the basis of the resource allocated thereto. At the receiving terminal 5, the event is received and the necessity of the subject to be obtained on the basis of the event is evaluated so that request data requesting the subject is transmitted to the server 2 on the basis of the result of evaluation. Then, the subject provided by the server 2 in response to the request data is obtained on the basis of the event.
Global server load balancing
A global server load-balancing (GSLB) switch serves as a proxy to an authoritative DNS and communicates with numerous site switches that are coupled to host servers serving specific applications. The GSLB switch receives from site switches operational information regarding host servers within the site switches neighborhood. When a client program requests a resolution of a host name, the GSLB switch, acting as a proxy of an authoritative DNS, returns one or more ordered IP addresses for the host name. The IP addresses are ordered using metrics that include the information collected from the site switches or based on other metric information. Examples of metrics include weighted site, weighted IP, and active bindings metrics. The GSLB switch places the address that is deemed “best” at the top of the list.

Directed acyclic graph computation by orienting shortest path links and alternate path links obtained from shortest path computation
Each network node in a network is configured for calculating a directed acyclic graph that provides at least one path from all the other network nodes toward the one network node. The network node performs a modified shortest path first calculation by identifying next-hop nodes adjacent to the network node, and orienting the link of each next-hop node toward itself (i.e., the origin).

The paths of the nodes form a directed acyclic graph from any other network node toward the origin, enabling distribution of the directed acyclic graph to the other network nodes for optimized reachability to the network node.

Lidar system for remote determination of calibrated, absolute aerosol backscatter coefficients
A lidar system capable of remotely identifying calibrated absolute aerosol backscatter coefficients of atmospheric aerosol particles by transmitting a beam of light and spectrally separating the intensity of Rayleigh and Mie backscattering is disclosed. The transmitter features high pulse energy to generate sufficient Rayleigh backscattering, enabling atmospheric scanning in a timely manner. The transmitter employs a seeded Nd:YAG laser and a seeded stimulated Raman scattering wavelength shifter to achieve narrow bandwidth, eye-safe laser pulses. The receiver employs a telescope, collimating lens, beam splitter, molecular absorption filter, focusing lenses, and avalanche photodiodes. Mie backscattering is blocked by the molecular absorption filter to provide a Rayleigh signal, which is used with knowledge of atmospheric density to calibrate the Mie signal. The system is intended for atmospheric research and aerosol monitoring applications where calibrated Mie scattering intensity is necessary to measure the optical depths of aerosol structures such as plumes, clouds, and layers.

Depth selective pH measurement and UV exposure measurement
A Raman spectrum is measured inside animal tissue, such us human skin tissue, at a selected depth from a surface the tissue. A pH value is computed using a function that assigns a pH value as a function of the measured Raman spectrum. The computation may involve computing a number representing a ratio of concentrations of a protonated and a deprotonated version of a chemical substance from the Raman spectrum and generating pH information on the basis of said number. The chemical substance is for example a form of Urocanic acid (UCA). UV exposure is measured from the weight of the spectrum of cis-UCA.

Method of measuring asymmetry in a scatterometer, a method of measuring an overlay error in a substrate and a metrology apparatus
In a method of measuring asymmetry in a scatterometer, a target portion is illuminated twice, first with 0° of substrate rotation and secondly with 180° of substrate rotation. One of those images is rotated and then that rotated image is subtracted from the other image. In this way, asymmetry of the scatterometer can be corrected.
Test apparatus and method
Previous testing of such test pieces as fan blades utilized in gas turbine engines has involved application of paint markings to identify fragments upon fragmentation of the test piece. Such fragmentation causes debris which will obscure paint markings and the paint itself may create clouds of dust obscuring visual images of the test piece under test conditions. By applying an image pattern comprising a number of lingering image patches, typically in the form of thermal patches upon the test components, and arranging the test components to be within an enclosure which is evacuated it will be appreciated that these image patterns linger and can be viewed by an appropriate monitor over a period at least of the test conditions. Utilization of extra visual spectrum radiation images extends the period when clear images of the test piece under test conditions can be seen and analyzed.
Optical rangefinder for an electro-active lens
Several devices for determining a distance of an object a user of an electro-active lens is looking at are presented. Once the distance is determined, the devices may alter the optical power of the electro-active lens to ensure that the object is correctly focused. Optical range finding is a possible means for carrying out this task. An active rangefinder may emit optical radiation from a transmitter directed at the object. The optical radiation may then be reflected off the object. The reflected optical radiation may then be received with an appropriate receiver. The received optical radiation may then be processed by appropriate circuitry to determine a distance to the object. A passive rangefinder works without a transmitter. Instead, an appropriate receiver receives ambient sources of light from the object. The received light may then be processed by appropriate circuitry to determine a distance to the object.
