System and method for protecting network resources from denial of service attacks
The present disclosure generally pertains to systems and methods for protecting network resources from denial of service attacks. In one exemplary embodiment, a responder stores an access filter value used to determine whether an incoming message frame has been transmitted from an authorized user. In this regard, a user communication device includes logic for determining the access filter value stored at the responder and includes the access filter value in a message frame transmitted from the computer to the responder. The responder compares the received access filter value to the stored access filter value. If such values match or otherwise correspond, the responder authenticates the message frame. However, if such values do not match or otherwise correspond, the responder discards the message frame. Thus, the responder processes authenticated message frames and discards unauthenticated message frames thereby preventing denial of service attacks from malicious users. |

Technique for effectively utilizing limited bandwidth of a communications network to deliver programming content
To effectively utilize the bandwidth of a cable TV network, which is limited, analog TV program material is digitized and compressed before its transmission over the network. The resulting signals consume only part of the analog TV band traditionally needed for transmission of the analog TV program material. The newly available bandwidth in the analog TV band may be utilized for other cable TV services, e.g., video-on-demand (VOD) services. A reception gateway is employed at a user location to frequency-translate any VOD signals, transmitted through the analog TV band, to another frequency band, thereby avoiding disturbing the normal operation of a set-top terminal in receiving the analog TV program material through the analog TV band at the user location. |

Automatic sharing of online resources in a multi-user computer system
A software tool assists users of a computer network to share items from each others' personal workspaces without requiring manual interaction on the users' part to receive and store items therein. An authoring user enters a command to share the object with “target recipients” and identifies the target recipients. Thereafter, the computer system creates records corresponding to the shared object in the workspaces of the target recipients. The records include pointers to the shared object. When a target recipient elects to open the records, it causes the computer system to access the author's workspace and create a copy of the personal object for the target recipient, who is then free to interact with the copy as if it were in his own personal workspace. Significantly, the target recipient does not participate in the distribution of the personal object from the author's workspace to his own. There is no administrative overhead as is required commonly in e-mail distribution systems. |

Cache stashing processor control messages
A system and method have been provided for pushing cacheable control messages to a processor. The method accepts a first control message, identified as cacheable and addressed to a processor, from a peripheral device. The first control message is allocated into a cache that is associated with the processor, but not associated with the peripheral device. In response to a read-prompt the processor reads the first control message directly from the cache. The read-prompt can be a hardware interrupt generated by the peripheral device referencing the first control message. For example, the peripheral may determine that the first control message has been allocated into the cache and generate a hardware interrupt associated with the first control message. Then, the processor reads the first control message in response to the hardware interrupt read-prompt. Alternately, the read-prompt can be the processor polling the cache for pending control messages. |

Channel communication array queues in hardware system area
A bi-directional and full duplex facility for permitting both the IO processor and the Channel to write CCA messages on their respective queues at the same time. IOP messages to the channel are stored on the TO_CHN queue and Channel messages to the IOP on the TO_IOP queue. CCA Queues replace hardware CCAs due to increasing transmission capabilities of current IO processors and Channel processors. Even though the mechanism is similar, the present invention provides some benefits in the use of signaling. The IOP does not have to signal the Channel each time it puts something on its outbound queue. Each queue contains multiple slots. This allows the IOP and Channel to write multiple messages on the targeted queue without encountering a CCA busy signal. The actual queues are now structured in hardware system memory. |

Hierarchical tree-based protection scheme for mesh networks
In a hierarchical tree-based protection scheme, a node in a mesh network is designated as a root node of a spanning hierarchical protection tree and subsequently invites each adjacent node to become its child within the tree. If the inviting node provides a more capacious protection path to the root node than is currently enjoyed by the invitee, the invitee designates the inviting node as its primary parent and assumes a new tree position. Otherwise, the invitee designates the inviting node as a backup parent. A node assuming a new tree position invites all adjacent nodes except its parent to become its child. The invitations propagate throughout the network until a spanning hierarchical protection tree is formed. Upon a subsequent failure of a straddling link, the tree may be used to re-route data. Further, given a tree link failure, protection switching is quickly achieved at a disconnected node through use of a backup parent as the new primary parent. Dynamic tree reconfiguration in the event of network topology changes may be limited to the network area surrounding the change. |

Scanning microscope and adjusting method for the same
A scanning microscope includes an objective lens for focusing illumination light onto a specimen; a scanning device for deflecting and scanning the illumination light; a pupil-projection optical system for illuminating a pupil of the objective lens with the scanned illumination light; and a total-magnification specifying unit for specifying a total magnification. An optical-system selecting unit changes at least one of the objective lens and the pupil-projection optical system such that a magnification of an optical system including the objective lens and the pupil-projection optical system is equal to or less than the total magnification specified by the total-magnification specifying unit and that the numerical aperture of the optical system is maximized. A deflection-angle determination unit determines a deflection angle of the illumination light deflected by the scanning device based on the ratio of the magnification of the optical system to the total magnification to achieve the total magnification. |

Ultra-broadband UV microscope imaging system with wide range zoom capability
An ultra-broadband ultraviolet (UV) catadioptric imaging microscope system with wide-range zoom capability. The microscope system, which includes a catadioptric lens group and a zooming tube lens group, has high optical resolution in the deep UV wavelengths, continuously adjustable magnification, and a high numerical aperture. The system integrates microscope modules such as objectives, tube lenses and zoom optics to reduce the number of components, and to simplify the system manufacturing process. The preferred embodiment offers excellent image quality across a very broad deep ultraviolet spectral range, combined with an all-refractive zooming tube lens. The zooming tube lens is modified to compensate for higher-order chromatic aberrations that would normally limit performance. |

Optical amplication module, optical amplifier, optical communication system, and white light source
The present invention relates to an optical amplifier and the like having a flatter gain spectrum in the wavelength band of 1490 nm to 1520 nm than before. The optical amplifier according to the present invention comprises an Er-doped optical waveguide and a Tm-doped optical waveguide having gain spectra difference from each other in the wavelength band. The signal light entered through the input end is first amplified by the Er-doped optical waveguide, and thereafter is amplified by the Tm-doped optical waveguide. The gain deviation of the amplified signal light, which has been amplified in the Er- and Tm-doped optical waveguides and outputted through the output end, can be reduced over the wavelength band. |

Low-average-power parabolic pulse amplification
There is provided a parabolic pulse amplifier for amplifying a pulse light signal. The amplifier comprises an ytterbium-doped amplification waveguide pumped using a pump source with a pump central wavelength substantially offset from the absorption transition peak wavelength. The pump wavelength is selected such that the absorption coefficient of pump light and the gain coefficient of the signal are substantially equal in the amplification waveguide such that the amplification gain is distributed substantially uniformly along the amplification waveguide. |

Wavelength conversion devices having multi-component output faces and systems incorporating the same
The present invention relates generally to wavelength conversion devices and laser projection systems incorporating the same. According to one embodiment of the present invention, wavelength conversion devices are provided without limitation of their field of use to laser projection systems. For example, the wavelength conversion device may comprise an axial waveguide portion and a pair of lateral planar waveguide portions confined between a pair of relatively low index cladding layers. The effective index of refraction in the axial waveguide portion of the waveguide region and the effective index of refraction in the lateral planar waveguide portions of the waveguide region are established such that the relatively low intensity laterally distributed parasitic light is characterized by a scattering angle θ that is at least as large as the beam divergence angle of the relatively high intensity light propagating in the axial waveguide portion. |

Variable cross-coupling partial reflector and method
When illuminated with a plane wave a variable cross-coupling partial reflector reflects a specific amount of a cross-polarized field and a specific amount of a co-polarized field and transmits the remaining power with low attenuation. This is achieved with a pair of frequency selective surfaces (FSS) that are rotated with respect to the incident plane wave. The FSSs can be fixed with a given alignment for a particular application or a tuning mechanism can be provided to independently rotate the surfaces and adapt the reflected co- and cross-polarized fields to changing requirements. Of particular interest is the ability to provide a specific amount of cross-polarized reflected power while reflecting no co-polarized field over a certain range of wavelengths. This will be useful to increase power efficiency in, for example, wave power sources that utilize quasi-optical power by causing oscillations in reflection amplifier arrays. |
