A stack pointer is copied to a stack pointer base to debug stack underflow. A move instruction, used to initialize the stack pointer, is modified to additionally copy the stack pointer to a stack pointer base register. During a course of execution in a single context, the stack pointer base sticks to the initial base value while the stack pointer is altered by a succession of PUSH and POP instructions. By monitoring for equivalence in the stack pointer and the stack pointer base values, a balanced number of PUSH and POP instructions is detected. If an equal number of PUSH and POP instructions is detected and an additional POP instruction is programmed, a stack underflow condition exists, an exception condition signaled, and exception flag produced. The exception condition allows the stack to be protected from an excessive POP instruction retrieving data out of context and subsequent loss of stack data.

US07752262B2 Slow-dynamic load balancing system and computer-readable medium
A load balancing system and a corresponding computer-readable medium are proposed. The load balancing system is used in environments (e.g., implementing a licensing management application) wherein each client is associated with a preferred server storing specific information for the client. Each client periodically detects a workload and a response time of all the servers. The client selects a subset of nearest servers (according to their response times). The server in that subset with the lowest workload is set as an eligible server. Whenever a ratio between the workload of the preferred server and the workload of the eligible server exceeds a predefined threshold value (e.g., 1.1), the client switches to the eligible server (transferring the corresponding specific information). The system of the invention exhibits a slow dynamic, and tends to reach a steady condition (wherein the specific information of the clients is not continuously moved across the system).
US07752258B2 Dynamic content assembly on edge-of-network servers in a content delivery network
The present invention enables a content provider to dynamically assemble content at the edge of the Internet, preferably on content delivery network (CDN) edge servers. Preferably, the content provider leverages an “edge side include” (ESI) markup language that is used to define Web page fragments for dynamic assembly at the edge. Dynamic assembly improves site performance by catching the objects that comprise dynamically generated pages at the edge of the Internet, close to the end user. The content provider designs and develops the business logic to form and assemble the pages, for example, by using the ESI language within its development environment. Instead of being assembled by an application/web server in a centralized data center, the application/web server sends a page template and content fragments to a CDN edge server where the page is assembled. Each content fragment can have its own cacheability profile to manage the “freshness” of the content. Once a user requests a page (template), the edge server examines its cache for the included fragments and assembles the page on-the-fly.

Context information is created in the first system pertaining to the environment within which the work is to be performed. The context information forms a context hierarchy having a root context and one or more descendant contexts. Information is propagated from the first system to the second system enabling re-creation at the second system of context information pertaining to the leaf context only.

US07751873B2 Wavelet based feature extraction and dimension reduction for the classification of human cardiac electrogram depolarization waveforms
A depolarization waveform classifier based on the Modified lifting line wavelet Transform is described. Overcomes problems in existing rate-based event classifiers. A task for pacemaker/defibrillators is the accurate identification of rhythm categories so correct electrotherapy can be administered. Because some rhythms cause rapid dangerous drop in cardiac output, it's desirable to categorize depolarization waveforms on a beat-to-beat basis to accomplish rhythm classification as rapidly as possible. Although rate based methods of event categorization have served well in implanted devices, these methods suffer in sensitivity and specificity when atrial/ventricular rates are similar. Human experts differentiate rhythms by morphological features of strip chart electrocardiograms. The wavelet transform approximates human expert analysis function because it correlates distinct morphological features at multiple scales. The accuracy of implanted rhythm determination can then be improved by using human-appreciable time domain features enhanced by time scale decomposition of depolarization waveforms.

One display comprises a side-illuminated light guide associated with conditions for total internal reflection. A first surface of the light guide is elastomeric. Disposed against this elastomeric surface is an active layer that selectively deforms the elastomeric surface in locations that can correspond to display pixels. This resulting change in the geometry of the elastomeric surface can be sufficient to defeat the conditions for total internal reflection. When appropriate, light is reflected by the particular deformation and is ejected from another surface of the light guide. In this case, each location that allows light to exit could represent an activated display pixel. In certain situations, color flat panel displays of varying sizes may further implement field sequential color and time-multiplexed optical shuttering.
