Zero-copy network I/O for virtual hosts
ActiveUS20070061492A1Eliminate the problemSolve excessive overheadDigital computer detailsTransmissionData packVirtualization
Techniques for virtualized computer system environments running one or more virtual machines that obviate the extra host operating system (O / S) copying steps required for sending and receiving packets of data over a network connection, thus eliminating major performance problems in virtualized environment. Such techniques include methods for emulating network I / O hardware device acceleration-assist technology providing zero-copy I / O sending and receiving optimizations. Implementation of these techniques require a host O / S to perform actions including, but not limited to: checking of the address translations (ensuring availability and data residency in physical memory), checking whether the destination of a network packet is local (to another virtual machine within the computing system), or across an external network; and, if local, checking whether either the sending destination VM, receiving VM process, or both, supports emulated hardware accelerated-assist on the same physical system. This optimization, in particular, provides a further optimization in that the packet data checksumming operations may be omitted when sending packets between virtual machines in the same physical system.

InactiveUS7188482B2Easy to interpret, calibrate and implementMaximize distanceAir-treating devicesSpace heating and ventilationOnline algorithmAir filter
The present invention is directed to a mathematical approach to detect faults by reconciling known data driven techniques with a physical understanding of the HVAC system and providing a direct linkage between model parameters and physical system quantities to arrive at classification rules that are easy to interpret, calibrate and implement. The fault modes of interest are low system refrigerant charge and air filter plugging. System data from standard sensors is analyzed under no-fault and full-fault conditions. The data is screened to uncover patterns though which the faults of interest manifest in sensor data and the patterns are analyzed and combined with available physical system information to develop an underlying principle that links failures to measured sensor responses. These principles are then translated into online algorithms for failure detection.

System and method for facilitating context-switching in a multi-context computer system
InactiveUS6944699B1Software simulation/interpretation/emulationMemory systemsOperational systemProcedure calls
A virtual machine monitor (VMM) is included in a computer system that has a protected host operating system (HOS). A virtual machine running at least one application via a virtual operating system is connected to the VMM. Both the HOS and the VMM have separate operating contexts and disjoint address spaces, but are both co-resident at system level. A driver that is downloadable into the HOS at system level forms a total context switch between the VMM and HOS contexts. A user-level emulator accepts commands from the VMM via the system-level driver and processes these commands as remote procedure calls. The emulator is able to issue host operating system calls and thereby access the physical system devices via the host operating system. The host operating system itself thus handles execution of certain VMM instructions, such as accessing physical devices.

ActiveUS7203554B2Reduce in quantityProlong lifeElectric testing/monitoringSpecial data processing applicationsControl systemPredictive controller
An MPC Control system provides a life extending control that includes life-extending goals in the performance index of the MPC controller and limits in the inequality equations. The MPC controller performs the normal functions of a control system for a physical system, but does so in a manner that extends the life or time-to-next maintenance or reduces the number of parts that need to be replaced. If the life extending functions do not degrade other control functions, they can be always enabled, making the system less expensive to maintain. If the life extending functions degrade some other control functions, they can be adjusted in-the-field or on-the-fly to stretch the time-until-maintenance until it is more convenient, but with some impact on performance.

System for establishing a cryptographic key depending on a physical system
ActiveUS20120072737A1Reduction of informationReduce decreaseKey distribution for secure communicationDigital data processing detailsComputer hardwareCryptographic nonce
In systems for establishing a cryptographic key depending on a physical uncloneable function (PUF) it may be a problem that internal information correlated with the cryptographic key is leaked to the outside of the system via a side-channel. To mitigate this problem a cryptographic system for reproducibly establishing a cryptographic key is presented. The system comprises a physical system comprising a physical, at least partially random, configuration of components from which an initial bit-string is derived. An error corrector corrects deviations occurring in the initial bit-string. Through the use of randomization the error corrector operates on a randomized data. Information leaking through a side channel is thereby reduced. After error correction a cryptographic key may be derived from the initial bit-string.

A method for simulating a physical system using finite element techniques, wherein two or more distinct models corresponding to distinct regions within the modeled system are solved, each with a corresponding evaluator. Nodes which lie on the boundaries between the models may have different values corresponding to the different models. When a particular model is solved, the evaluator for that model is used to obtain the appropriate values for each of these common nodes. In one embodiment, a first model is defined, then a region corresponding to a particular feature within the system is carved out of it. A finite element model corresponding to the feature is then inserted into the region. The finite elements may be adapted to share nodes on the boundaries between them.

Physical access systems and methods securely grant physical access to restricted areas in high-volume applications. An electronic device, such as a smartphone, stores a digitally signed physical access rights file. An individual uses this rights file to gain access to a restricted area only after self-authenticating to the device. A physical access control system receives the rights file, validates it, and determines whether to permit passage through a physical barrier. The determination may be made by a physical barrier system, or by a remote access control headend. An access control gateway, which may be an access control headend, may either unlock the physical barrier system when the electronic device is near the physical barrier, or it may transmit an authorization code to the electronic device and the physical barrier system, whereby passage is only permitted if the barrier system subsequently receives the authorization code from the electronic device using near field communications.

Selective sampling for assessing structural spatial frequencies with specific contrast mechanisms
The disclosed embodiments provide a method for acquiring MR data at resolutions down to tens of microns for application in in vivo diagnosis and monitoring of pathology for which changes in fine tissue textures can be used as markers of disease onset and progression. Bone diseases, tumors, neurologic diseases, and diseases involving fibrotic growth and / or destruction are all target pathologies. Further the technique can be used in any biologic or physical system for which very high-resolution characterization of fine scale morphology is needed. The method provides rapid acquisition of signal at selected values in k-space, with multiple successive acquisitions at individual k-values taken on a time scale on the order of microseconds, within a defined tissue volume, and subsequent combination of the multiple measurements in such a way as to maximize SNR. The reduced acquisition volume, and acquisition of only signal values at select places in k-space, along selected directions, enables much higher in vivo resolution than is obtainable with current MRI techniques.
