The present invention provides systems and methods for monitoring in real time the physiological status of one or more subjects, especially subject engaged in potentially hazardous or dangerous activities. Systems include wearable items with one or more physiological sensors and a local data unit (LDU) operatively coupled to the sensors. The LDUs digitize and filter sensor data, extract physiological parameters, determine abnormal or not acceptable physiological conditions, and communicate to external monitoring facilities. The external facilities display status and data concerning monitored subjects. In preferred embodiments, communication between the LDUs and the external monitoring facilities dynamically adjusts to the condition of the subjects and to system changes such as subjects and external facilities entering and leaving and / or moving from place to place. The invention also provides program products for performing this invention's methods.

A computer system analysis tool and method that will allow for qualitative and quantitative assessment of security attributes and vulnerabilities in systems including computer networks. The invention is based on generation of attack graphs wherein each node represents a possible attack state and each edge represents a change in state caused by a single action taken by an attacker or unwitting assistant. Edges are weighted using metrics such as attacker effort, likelihood of attack success, or time to succeed. Generation of an attack graph is accomplished by matching information about attack requirements (specified in “attack templates”) to information about computer system configuration (contained in a configuration file that can be updated to reflect system changes occurring during the course of an attack) and assumed attacker capabilities (reflected in “attacker profiles”). High risk attack paths, which correspond to those considered suited to application of attack countermeasures given limited resources for applying countermeasures, are identified by finding “epsilon optimal paths.”

Methods and systems for providing directory services for peer-to-peer systems and applications are provided. Example embodiments provide a Peer-to-Peer Directory System (“PPDS”), which enables applications, especially those using peer-to-peer technology that desire to communicate directly with one another on different peer computer systems, to automatically discover working (current) network addresses for each other even when the network addresses of their respective computer systems change dynamically. The PPDS provides a community-based tracking system, a portion of which is implemented on each computer system that is a member of the community, to mutually track and store the network addresses of the other computer systems to which it has an associated relationship. The PPDS also provides a query mechanism that takes advantage of the relationship paths between the various computer systems to search for a current network address of a designated computer system.

A directed sequential hazard assessment weather radar system detects weather and hazards with low latency and high confidence in a hazard detection mode to detect a region of reflectivity and changes to an assessment mode after detecting the region of reflectivity. The weather radar system scans a volume in front of an aircraft to detect the region of reflectivity in the hazard detection mode using a multiscan process and a reflectivity pulse pattern. The weather radar system determines presence of a hazard in the region of reflectivity after detecting the region. The weather radar system changes to a turbulence pulse pattern in the assessment mode and scans the region of reflectivity with an auxiliary sweep to determine turbulence. The directed sequential hazard assessment weather radar system performs a qualification process by scheduling an additional radar scanning auxiliary sweep to determine if the turbulence is real.

A system and method for maintaining consistency between translational look-aside buffers (TLB) and page tables. A TLB has a TLB table for storing a list of virtual memory address-to-physical memory address translations, or page table entries (PTES) and a hardware-based controller for invalidating a translation that is stored in the TLB table when a corresponding page table entry changes. The TLB table includes a virtual memory (VM) page tag and a page table entry address tag for indexing the list of translations The VM page tag can be searched for VM pages that are referenced by a process. If a referenced VM page is found, an associated physical address is retrieved for use by the processor. The TLB controller includes a snooping controller for snooping a cache-memory interconnect for activity that affects PTEs. The page table entry address tag can be searched by a search engine in the TLB controller for snooped page table entry addresses. The TLB controller includes an updating module for invalidating or updating translations associated with snooped page table entry addresses. Translations in TLBs are thus updated or invalidated through hardware when an operating system changes a PTE, without intervention by an operating system or other software.

A method and system for providing an integrated building summary dashboard application. The dashboard can be implemented, for example, as a Rich Internet Application (RIA), which integrates with multiple data sources. A data warehouse can be utilized to consolidate and store the data related to a particular dashboard.

The dashboard can also be configured to include a data chart that provides a “glimpse” of information associated with key performance indicators. The data chart can be configured to utilize a target bar as input to an interactive what-if analysis, and an output can be utilized to automatically drive control automation system changes.

A security module detects and remediates malware from suspicious hosts. A file arrives at an endpoint from a host. The security module detects the arrival of the file and determines the host from which the file arrived. The security module also determines whether the host is suspicious. If the host is suspicious, the security module observes the operation of the file and identifies a set of files dropped by the received file. The security module monitors the files in the set using heuristics to detect whether any of the files engage in malicious behavior. If a file engages in malicious behavior, the security module responds to the malware detection by remediating the malware, which may include removing system changes caused by the set.

A computer system operation registers as an event when an operation potentially characteristic of malware occurs. Events are scored and when a threshold is reached indicative of a possible malware infection a restore point is created. Many restore points are created. When a user decides to restore the system because of the presence of malware a malware report is retrieved. The malware report describes characteristics of a particular piece of malware. The malware report is compared to the restore point logs that had been created earlier. Any number of malware reports are compared to the restore point logs. A restore point log that shares many of the same system changes or other effects also present in a malware report is likely to be an indication of the beginning of a malware infection. The matched restore point log is recommended to the user as the best restore point.

Thus, a user changing smart phone platforms can convert their current smart phone settings to equivalent settings on the new phone platform, and their new phone can then be configured using the user's converted settings stored in the cloud. By storing all the user's relevant information in the cloud, this information may be accessed anywhere and may be used to configure a large number of different devices according to the user's settings.

A lane departure control system is provided which steers a vehicle toward the center of a lane of a road at a first yaw rate by a controlled angle when the vehicle is determined to be about to deviate from the lane. Afterwards, when the vehicle is determined to be traveling toward a virtual line defined near a lane boundary, the system steers the vehicle by a correction angle so as to orient the vehicle parallel to the virtual line at a second yaw rate. The system changes the value of the first yaw rate at a first rate within the controlled angle and also changes the value of the second yaw rate at a second rate within the correction angle. An absolute value of the second rate is set smaller than that of the first rate, thereby minimizing an undesirable physical load on a driver of the vehicle.
