Abstract: A method and system for managing a secure network boot of a server blade. The server blade is part of a server blade chassis, which holds multiple server blades that communicate with outside devices via a Pre-boot eXecution Environment (PXE) enabled network interface card. When a server blade receives a response from a PXE boot server offering a boot program download, a Remote Supervisory Adapter (RSA) card, managed by a remote manager, compares the identity of the responding PXE boot server with a list of trusted PXE boot servers. Only if the responding PXE boot server is on the list of trusted PXE boot servers will the server blade be allowed to use a boot program provided by the responding PXE boot server.

Abstract: A data channel includes a data detector that approximates both inter-symbol-interference (ISI) and random timing perturbations using a single finite-state hidden Markov model. The ISI is approximated by a finite impulse response and the timing perturbations are approximated by a first order random walk. The data signal, which is subject to inter-symbol interference and timing perturbations, is sampled periodically over a succession of time epochs without regard to timing perturbations. Timing perturbation values and data states are then assigned for each epoch, and each timing perturbation value is paired with each data state to arrive at a set of composite states. Probabilities are then assigned between composite states in successive epochs to arrive at the most probable composite state sequence corresponding to the sequence of detected data values from the sampled data. A Viterbi algorithm is then applied to find the maximum likelihood sequence of composite states.

Abstract: A system and method for terrain rendering using a limited memory footprint is presented. A vertical ray intersects a terrain data map at an angle which includes a minor step size. Weighting factors are assigned to triangular data sampling values and quadrilateral data sampling values based upon a vertical ray's minor step size. As a vertical ray's minor step size increases, a triangular data sampling's weighting factor increases and a quadrilateral data sampling's weighting factor decreases. Weighted triangular data sampling values and weighted quadrilateral data sampling values are combined to generate a vertical ray image point value.

Abstract: A field effect transistor is formed with a sub-lithographic conduction channel and a dual gate which is formed by a simple process by starting with a silicon-on-insulator wafer, allowing most etching processes to use the buried oxide as an etch stop. Low resistivity of the gate, source and drain is achieved by silicide sidewalls or liners while low gate to junction capacitance is achieved by recessing the silicide and polysilicon dual gate structure from the source and drain region edges.

Abstract: A system, method and program product in a Model-View-Controller architecture for communicating between objects such as a Model object and a View object. A transform object is provided in the interface between any of the conventional Model, View and Controller objects such that transformation of data types into appropriate other data types is accomplished outside of the MVC object. This relieves the recipient MVC object of the responsibility of being designed to support multiple data types in order to perform a function.

Abstract: A system and method for capturing a plurality of business requirements using a Business Process Outsourcing Language (BPOL), an XML representation for expressing business process flow rules, preferences, business rules and event-action mappings as well as service links, to automate the process of generating business processes for use with Web services. BPOL is used to dynamically construct a search script for an advanced Web services discovery engine to find Web services from both UDDI registries and Web services Inspection Language (WSIL) documents and then create a qualified service list. Then a service selection problem is mapped into a solution space {0,1} for use by an optimization algorithm that performs second level service selection of the best set of services based on the requirements.

Abstract: An apparatus, a method, and a computer program product are provided for time reduction and energy conservation during address distribution in a high speed memory macro. To address these concerns, this design divides the typical data arrays into sets of paired subarrays, divides the conventional memory address latches into separate sets, and interposes one set of memory address latches between each pair of subarrays. Therefore, time is saved because the address signals have less wire length to travel and energy is saved because only one set of address latches needs to be powered on for each transmission.

Abstract: A method to change the IP address of a server from a remote operator station, where that server comprises an HTTP server having a first IP address, and where that server is capable of communicating with one or more remote operator stations. One of those remote operator stations submits to the server, using the first IP address, an IP address change request. That IP address change request includes discontinuing use of the first IP address and commencing use of a second IP address. After receipt of the IP address change request, the server generates an HTML page comprising an embedded applet, where that applet is capable of monitoring the TCP/IP connection between the remote operator station and the server. The server provides that HTML page/applet to the remote operator station. Thereafter, the remote operator station continuously displays the status of the IP address change request using the provided applet.

Abstract: A view controller, such as a scroll bar, for a first application which is currently displayed within an inactive window is detached and remotely displayed within an active window in addition to the view controller associated with the content of that active window. A Dynamic Data Exchange (DDE) link is then established between the remotely displayed view controller and the first application such that user inputs to the remotely displayed view controller can be utilized to modify the display of the first application without requiring the user to activate the inactive window. In this manner data within the first application can be scrolled and visually accessed by the user while the user is working within an active window, without requiring the user to toggle the focus back and forth between two windows.

Abstract: A user of a client computer is authenticated for first and second applications executing in a server. The server authenticates the user for the first application based on a userID and password of the user, and the server returns a token of the authentication to the client computer. The client computer uses the token to request a first function performed by the first application. The user subsequently requests a second function performed by the second application. In response, the client computer determines that the user has not yet been authenticated for the second application and sends a request to the server for an authentication ticket for using the second application. In response to the request for the authentication ticket, the server checks the authentication token. If valid, the server returns an authentication ticket to the client computer. The client computer requests the second function to the server. The client computer request for the second function includes the authentication ticket.

Abstract: A pseudo Set/Reset latch circuit is configured with modified NOR or NAND gates wherein one of the series pull-up devices or pull-down devices is removed. A minimum of three pseudo Set/Reset latches may be coupled as a ring oscillator generating an output and a non-skewed complementary output. Additionally, feed-forward inverting stages may be coupled in parallel with inverting paths in the ring oscillator primary path to further increase the frequency range of the ring oscillator. The pseudo Set/Reset latch circuits and the feed-forward inverting stages may be configured with voltage controlled devices that alter the delay of the stages as a means for varying the frequency of the ring oscillator either by varying the current drive of the circuitry driving the output of the latch stages or by varying the conductance of devices coupling between the latch stages. Feedforward inverting stages may comprise pseudo latches or inverter gates.
