Abstract:
A method for authenticating a user for use of a server computing device wherein the server computing device is connected by a network to a host device. Generating a key representation image having thereon a plurality of individual key images placed at random positions, each corresponding to a possible character value in an authentication phrase. Accepting a sequence corresponding to locations of mouse clicks representing user selections of character values in an attempted authentication phrase. Verifying that the sequence of location values corresponds to a correct authentication phrase by mapping the locations of the mouse clicks to the locations of the randomly placed key images. Alternatively, accepting a sequence corresponding to a transformation of personal identification number based on a random number and a numerical operation or selection in a matrix.
Abstract:
Coated polymeric material is sized and fed into an extruder. The material is cooled to maintain the temperature of the polymeric material below its melt index. The shearing action of the extruder separates the coating material from the polymeric material. The discharge from the extruder is polymeric material and coating material. These materials are separated and recovered.
Abstract:
A damping system including a first set of plates having one end thereof attached to a first vertically extending structural element, a second set of plates having one end thereof attached to a second vertically extending structural element spaced in a horizontal direction from the first vertically extending structural element, and arranged such that the first set of plates has a second end portion extending towards and overlapping with a second end portion of the second set of plates at an overlapping region, and further including an energy dissipating material provided in the overlapping region for connecting the first set of plates and the second set of plates.
Abstract:
Role-based hierarchical access control system and method. A computer system having a data storage capacity and a central processing unit and at least one resource has an access control data structure defining role-based access control lists for the resource, wherein the access control list defines based on the role of a user the types of access that the user may have to the at least one resource. A hierarchy of roles having at least a first role and a second role wherein the second role inherits the permissions granted to the first role for the at least one resource. Access to the resource is determined by comparing roles defined to have access privileges to the resource and the permissions granted to such roles to the role of an entity seeking access to the resource.
Abstract:
Disclosed herein is a nozzle box assembly including a torus, a steam path ring, and a bridge ring. The torus has a plurality of steam inlets and an annular steam outlet. The steam path ring has an annular steam inlet, the annular steam inlet has an inner diameter (ID) and an outer diameter (OD), the steam path ring is disposed downstream of the torus. The bridge ring has an annular steam inlet and an annular steam outlet, the annular steam outlet has an ID and an OD, the bridge ring is disposed between the torus and the steam path ring, the bridge ring annular steam outlet is adjacent to the steam path ring annular steam inlet, and the steam path ring annular steam inlet OD is greater than the bridge ring annular steam outlet OD and the steam path ring annular steam inlet ID is smaller than the bridge ring annular steam outlet ID.
Abstract:
Solid particle erosion in a steam turbine is minimized by diverting through holes in appendages of outer rings of the diaphragms, a portion of the steam from the steam flow path thereby bypassing downstream rotating components. The hole through the first stage appendage lies in communication with a passage through a downstream outer ring of a following stage such that the diverted solid particle containing steam may be extracted from the steam flow path and passed to the feed water heater of the turbine. The hole in the second stage appendage diverts steam from between the first and second stages and about the second stage. Solid particle erosion in various regions, i.e., the trailing edge of the stator vanes, along the surfaces of the buckets and in the regions of the cover and its connection with the buckets as well as the sealing devices are thereby minimized.
Abstract:
Secure authentication to a remote server including transmitting login credentials from the secure storage device to the remote server. Transmitting from the secure storage device to the host computer a server list containing a list of servers available for secure authentication using the secure storage device. Using the list to establish a connection from the host to the remote server and to request the secure storage device to present the login credentials to the remote server. Transmitting from the secure storage device the login credentials and a login software module to the host computer. The login software module is automatically executed on the host computer to fill in the login page and to cause the transmission of the filled-in login page from the host computer to the remote server.
Abstract:
Secure communication between a resource-constrained device and remote network nodes over a network with the resource-constrained acting as a network node. The remote network nodes communicate with the resource-constrained device using un-modified network clients and servers. Executing on the resource-constrained device, a communications module implements one or more link layer communication protocols, operable to communicate with a host computer, operable to communicate with remote network nodes and operable to implement network security protocols thereby setting a security boundary inside the resource-constrained device.
Abstract:
A planar device for a pedal-equipped apparatus with a planar member attached to the inward portion of a pedal to protect a rider's body and/or clothing from contact with equipment components during the entire circular pedal rotation. This member may change from a closed, unexpanded position to an expanded position.
Abstract:
A method and apparatus for making real-time measurements of downhole properties during cement plug placement. A wired placement conduit is lowered downhole releasing a sensor package. The sensor package is capable of measuring downhole properties in real-time in the period while the cement plug sets.
