62 results about "Partial solution" patented technology

The partial solutions are associated with the nodes of the branching tree that are not leaves (as Samuel reminded me, except for the nodes that became leaves by pruning, these are partial solutions too). For example, if you're optimizing a function over a subset of R^4, an example of a partial solution would be (1,x2,2,x4),...

Network security monitoring system

A security monitoring system processes event messages related to computer network security in real time, evaluating inter-event constraints so as to identify combinations of events that are partial solutions to a predefined event correlation rule, and furthermore evaluating combinations of the partial solutions do determine if they together satisfy the predefined event correlation rule. A decision tree is formed based on the rule. Event messages are categorized into groups at leaf nodes of the tree in accordance with a plurality of intra-event constraints, and then the messages are correlated in accordance with a plurality of inter-event constraints at non-leaf nodes of the tree. When the inter-event constraint at a root node of the tree has been satisfied, a network attack alert is issued and protective actions may be taken.

NMR CryoMAS Probe for High-field Wide-bore Magnets

An MAS probe is disclosed for obtaining a substantial improvement in signal to noise (S / N) in triple-resonance high-resolution (HR) magic-angle-spinning (MAS) NMR of samples near room temperature (RT) in high-field magnets where the magnet's RT shim bore is greater than 60 mm. All critical circuit components, including the sample coils, are located along with the spinner assembly in a thermally insulated cold zone pressurized with helium gas. The spinner assembly attaches to a sealed, curved, rotor-loading tube to permit automatic sample change, and it is surrounded by a partially insulated jacket cooled with a cryogenic fluid, generally nitrogen gas. The MAS probe is also compatible with magic angle gradients, variable temperature operation, field locking, and commonly available closed-cycle cold fingers. One major challenge in implementing CryoMAS is solving the problem of gas leakage from the spinner bearing, drive, and exhaust nitrogen into the cold zone, as some components will necessarily be ceramic, some plastic, and some metal. It is not desirable to use helium for the spinner bearing and drive gases for cost reasons and to prevent risk of degradation of o-ring-sealed magnet cryostats. A pressurized helium atmosphere in the cold zone may be utilized to prevent nitrogen flow from the spinner exhaust streams or atmosphere into the cold zone. The drawback to a pressurized cold zone is that the heat transfer coefficient in dense helium at low temperatures is very high, making it challenging to cool the sample coils and all the large, critical, circuit components in a practical manner. Part of the solution here is to use a first-stage cooling-jacket around the major heat leaks near the spinner exhaust flows. The critical components may be insulated with fine glass wool or teflon foam and conduction cooled without cooling much of the cold zone below the temperature of the first-stage cooling. The use of coaxial sapphire capacitors allows the noise contributions from the most critical capacitors to be reduced to a minor fraction of the total.

The system comprises a routing engine which is configured to search for a path to connect a current pair of points in the set of pairs of points, wherein the path comprises a set of rectangles and vertices. The routing engine uses a routing database, which keeps track of previously routed nets that can obstruct the routing of the current pair of points. The system further comprises a satisfiability (SAT) solver which is capable of solving a set of constraints, wherein the set of constraints are associated with the routability of the set of pairs of points. The SAT solver additionally comprises a SAT database which maintains the set of constraints and a current partial solution to the set of constraints. The SAT database is used to update the routing database if the current partial solution changes.

Techniqes for super fast buffer insertion

A method of determining buffer insertion locations in an integrated circuit design establishes candidate locations for inserting buffers into a net, and selects buffer insertion locations from among the candidates based on slew constraints. The selection of buffer insertion locations preferably optimizes slack and buffer cost while keeping slew from any buffered node to any sink less than a required slew rate. The slew analysis computes an output slew SL(v) of a given buffer b inserted at a node v as SL(v)=RS(b)·C(v)+KS(b), where C(v) is the downstream capacitance at v, RS(b) is the slew resistance of buffer b, and KS(b) is the intrinsic slew of buffer b. The delay through a given buffer may also be computed based on signal polarity. However, the invention still preferably uses worst-case slew resistance and intrinsic slew in considering the slew constraints. If the selection of the buffer insertion locations results in no locations being selected due to slew violations, the present invention may advantageously find a partial solution by relaxing the slew constraint.

Welding shielding gas saver device

This device significantly reduces major reasons for shielding gas waste primarily in metal inert gas welding. Excess shielding gas stored at the end of each weld in the shielding gas delivery hose connecting the gas source to the welding machine creates a shielding gas flow-surge at the next weld start. This gas flow-surge creates shielding gas waste and can cause poor weld start performance. Other methods employed over the years to reduce shielding gas waste have been either complex, leaked, were not sufficiently robust for the environment, provided only partial solutions or did not provide shielding gas savings for welds longer than about 3 seconds. This device includes a delivery hose connecting the shielding gas supply to the welding machine, which has a small internal volume and a gas surge-restricting orifice at the gas solenoid end of the hose.
