摘要:
The invention that addresses the problem of authentication of the transport packet stream (which constitutes a flow within a session), which has been admitted into a managed packet network. Authentication and the subsequent policing of the flows supporting an identified client's authorized service prevent a large class of denial of service attacks described below. Specifically, the invention addresses two different matters: 1) key distribution and management 2) various forms of using a shared key for the authentication of transport packets on the user-to-network-interface (UNI).

The present invention specifies the mechanism for supporting end-to-end quality of service (QoS) reservations for an implicit reservations model using a Resource and Admission Control Function (RACF) apparatus. The invention teaches how to implement implicit resource reservations using the open-standard Resource and Admission Control Function (RACF), which is being standardized in ITU-T. Several methods are covered: 1) With a first method, a general distributed approach has been specified. 2) For a second method, the terminating RACF keeps the state of the reservations, so the resulting protocol is relatively simple, robust, and easy to implement. 3) A third method, which can be based on either of the above methods or their combination, starts reservations at both, the terminating and originating RACF ends and works toward the meet-me point.
摘要:
A dolly capable of allowing relatively heavy and bulky objects to be easily manipulated and moved without adding significantly to the dimension of the object thereby allowing the object to be easily moved through conventional door openings. Preferably, the dolly comprises a first frame having generally vertical legs mechanically coupled to a generally horizontal brace and a second frame having generally vertical legs mechanically coupled to a generally horizontal brace such that the first frame and the second frame are in position on opposite sides of the object and the generally horizontal braces are positioned under corresponding edges of the object. The generally vertical legs of the first frame and the second frame when moved into a more vertical orientation operate to mechanically lift the generally horizontal braces to lift the object and allow the object to be transported to a desired location.

The present disclosure provides for a recording device for creating an enhanced personalized image product. The recording device can include a display unit having a graphical user interface. The recording device can comprise a first camera and a second camera simultaneously recording a first image and a second image in a first person perspective and a second person perspective (or another first person perspective), respectively. A unit controller can be operatively coupled to the display unit and the recording unit. The unit controller can comprise a processor and a memory operatively coupled to the processor. The unit controller can be programmed to cause the recorded images to be generated on the display unit. The unit controller and the graphical user interface can allow a user to view the recorded images of the person and edit the recorded images on a single display unit.
摘要:
A filter for filtering radio frequency (RF) power transmitted from an electrostatic chuck (ESC) in a plasma processing system. The plasma processing system may include a heating element disposed at the ESC. The plasma processing system may further include a power supply. The filter may include a core member and a cable wound around and wound along the core member to form a set of inductors. The cable may include a plurality of wires, including a first wire and a second wire, a portion of the first wire and a portion of the second wire being twisted together, a first end of the first wire and a first end of the second wire being connected to the heating element, each of a second end of the first wire and a second end of the second wire being connected to a capacitor and being connected to the power supply.

Methods of reducing the permeability of a subterranean formation to aqueous-based fluids using a water-soluble relative permeability modifier that comprises a hydrophobically modified polymer, wherein the hydrophobically modified polymer is a reaction product of: a hydrophilic polymer that comprises a polymer selected from the group consisting of a polyvinylamine, a poly(vinylamine/vinyl alcohol), and an alkyl acrylate polymer; and, a hydrophobic compound comprising at least one alkyl chain having a carbon chain length between about 4 and about 22 carbons. The water-soluble relative permeability modifier may be placed within a subterranean drilling operation such that the water-soluble relative permeability modifier attaches onto surfaces within the subterranean formation to effect permeability of aqueous fluids.
摘要:
A method and apparatus for automating hub and spoke network trouble diagnostics in a communication network are disclosed. For example, the method retrieves provisioning and configuration data, access interface alarm information, and network facility status data related to the communication network by a diagnostic system, and identifies at least one of: a network configuration error, an access interface error, or a configuration error associated with at least one hub router or at least one spoke router, as the root cause of the problem of the communication network.
摘要:
Systems and methods for sealing a vascular opening such as an arteriotomy formed during a femoral artery catheterization procedure are described. The blood vessel is transiently occluded during application of therapeutic energy, such as high intensity focused ultrasound. The occlusion improves the efficiency of the therapy without causing damage to the blood vessel. Also described are methods for locating the arteriotomy, aligning the therapeutic applicator to the arteriotomy, and a station keeping procedure for maintaining alignment.
摘要:
Apparatus for remotely viewing and scanning microfilm at a first location, while controlling the viewing and scanning from a remote location, including a viewing and scanning device for generating a video feed and subsequently scanned images of the microfilm, a host computer at the first location in communication with the viewing and scanning device to receive the video feed and the scanned images, a user's computer at a remote location in communication with the host computer to receive the video feed and the scanned images from the host computer, and a virtual film movement control at the user's computer to control the movement of the microfilm at the first location. A virtual camera control at the remote location controls the camera of the viewing and scanning device.
摘要:
A multifunction warming device includes a clinical garment having an inside surface supporting a convective apparatus disposed to provide therapeutic warming of a patient's upper body during surgery. The warming device includes a clinical garment with an elongate convective apparatus supported on the inside of the garment, transversely to the garment, and running between its sleeves. The positioning of the convective apparatus in the clinical garment locates it against the chest of a patient wearing the garment and permits it to be deployed and used on the patient's upper body during and after surgery without removal of the clinical garment from the patient or removal of the convective apparatus from the clinical garment.
