Disclosed is a method and apparatus for detecting exploit code in network flows. Network data packets are intercepted by a flow monitor which generates data flows from the intercepted data packets. A content filter filters out legitimate programs from the data flows, and the unfiltered portions are provided to a code recognizer which detects executable code. Any embedded executable code in the unfiltered data flow portions is identified as a suspected exploit in the network flow. The executable code recognizer recognizes executable code by performing convergent binary disassembly on the unfiltered portions of the data flows. The executable code recognizer then constructs a control flow graph and performs control flow analysis, data flow analysis, and constraint enforcement in order to detect executable code. In addition to identifying detected executable code as a potential exploit, the detected executable code may then be used in order to generate a signature of the potential exploit, for use by other systems in detecting the exploit.

An integrated optimization and control technique integrates an optimization procedure, such as a linear or quadratic programming optimization procedure, with advanced control, such as model predictive control, within a process plant in which the number of control and auxiliary variables can be greater than the number of manipulated variables within the process plant. The technique first determines a step response matrix defining the correlation between changes in the manipulated variables and each of the process variables that are used during optimization. A subset of the control variables and auxiliary variables is then selected to be used as inputs to a model predictive control routine used to perform control during operation of the process and a square M by M control matrix to be used by the model predictive control routine is generated. Thereafter, during each scan of the process controller, the optimizer routine calculates the optimal operating target of each of the complete set of control and auxiliary variables and provides the determined target operating points for each of the selected subset of control and auxiliary variables to the model predictive control routine as inputs. The model predictive control routine determines changes in the manipulated variables for use in controlling the process from the target and measured values for each of the subset of the control and auxiliary variables and the M by M control matrix.

A security server qualifies the execution of programs for networked host computer systems using a database storing pre-qualified program signatures and defined policy rules associating execution permission qualifiers with execution control values. The server executes a control program in response to execution requests received via a communications network interface from identifiable hosts, wherein a predetermined execution request received from a predetermined host computer system includes an identification of a program load request, request context related data, and a secure program signature. The control program determines an execution control value based on an evaluation of the execution request relative to the pre-qualified program signatures and defined policy rules. The execution control value is then returned to the predetermined host computer system to securely qualify the execution of the program identified from the program load request.

In a digital camera, control operations, such as an AF (automatic focusing) operation which is performed immediately after zooming or panning of the camera, can be performed quickly in an appropriate manner. When a zoom lens 3 is driven to zoom “up”(“in”), a control processor and timing generator 40 uses, of imaging conditions data, such as distance measuring data and photometering data, which are obtained at a wide viewing angle before zooming up, a portion of the imaging conditions data corresponding to a “tele” (telephoto) viewing angle after zooming up, to thereby perform AF, AE, and / or AWB operations after zooming up. When the user pans the camera to shift the viewing angle out of the range of the original wide viewing angle, the data of an area of the image plane of the wide viewing angle closest to the image plane of a new post-panning viewing angle is reused. In a digital camera having a plurality of image capturing optical systems which are switched in response to a zoom position, data obtained by the pre-switching image capturing optical system is reused by a selected post-switching image capturing optical system.

Content of multiple digital bit streams with essentially the same renderable content, and situated at mutually remote locations, are played back in unison. First, time is synchronized among the processors that participate in a synchronized viewing session by playing back respective streams. Second, the playbacks are content-wise aligned, by rewinding or fast forwarding, to effect overall a precisely synchronized presentation. The content-wise alignment is achieved by means of a status message between processors that contains information characteristic of the sender's bit stream. If any participant, performs a control function (e.g. rewind, fast forward, stop), all other participants follow synchronously. The processor that initiates the session is deemed the initiator, a role that is thereafter assumed by the participant that has last performed a control function. The initiator directs all participants, at session startup, upon execution of each control function, and periodically, to synchronize their playbacks to that of the initiator, whereby all playbacks are synchronized and maintain in synchronization.

In a structured workflow system, a configurable workflow engine provides mechanisms for executing and scheduling the work items in a defined way. End users use their discretion and define their own “local” processes and “local” rules for processing work items, or deviate from predefined processes. The configurable workflow engine might be installed at a server to organize workflows and business processes where end users can define processing steps for incoming work items by setting up rules and defining workflows as part of a local workflow structure. By defining these rules and workflows, the further processing steps of future incoming work items can be automated. When an administrator directs the workflow engine to move from a current phase to a next phase, the workflow engine deals with the incomplete items by allowing the administrator to carry over work items (or might do it automatically). End -user consultation might be included in the carry-over decisions. The carried over work items are added as parallel activities to the next phase. The workflow engine handles imposing and executing control flow dependencies between tasks, thus providing a smooth transition from totally unstructured work to semi-structured or completely structured work. When the workflow engine encounters semantically correlated work items / tasks, the process engine assumes that these work items / tasks belong to the same process instance.

Provided is a display control device including a display control unit that performs control for displaying, on a screen, a pointer having a directed position a predetermined distance away from a position on the screen corresponding to an operation position of an operating object, depending on a variation in a position of the operating object detected in an operation area.

A base station communicates with mobile terminals existing within a subordinate cell, and in addition executes control to reduce interference from mobile terminals existing within adjacent cells. The base station measures the total interference power received from mobile terminals in all adjacent cells, and if the total interference power is greater than a preset value, issues a request to the base stations of all adjacent cells to reduce interference. The base station which has received the interference reduction request discriminates mobile terminals which impart interference to the base station which is the source of the interference reduction request, and reduces interference by either temporarily lowering the uplink data transmission rate or temporarily halting uplink data transmission for such mobile terminals.

One or more nodes on a communication network are selected and set as one node group. In each of the nodes, group identification information representing the node group to which the node belongs is stored in advance. The group identification information is attached to the header of a data packet to be transmitted, so that nodes constituting a node group that should commonly receive data can be readily identified by comparing the group identification information imparted to the transmitted data packet and the group identification information stored in each receiving node. Given node can choose to become a node of a particular function, such as a clock master node, in which case control is performed to delete, from the node group, a node having so far played the role of the node of the particular function in such a manner that there exists only one node of the particular function per node group.
