Abstract: A wearable device may include a user interface, a processor in communication with a memory having executable instructions, an application, and at least sensor configured to monitor and/or track health data of the user. The processor executes the instructions to identify and transmit abnormal health events to initiate a response from one or more predetermined contacts and/or services.

Abstract: Embodiments of delivery systems, devices and methods for delivering a prosthetic heart valve device to a heart chamber for expanded implementation are disclosed. More specifically, methods, systems and devices are disclosed for delivering a self-expanding prosthetic mitral valve device to the left atrium, with no engagement of the left ventricle, the native mitral valve leaflets or the annular tissue downstream of the upper annular surface during delivery, and in some embodiments with no engagement of the ventricle, mitral valve leaflets and/or annular tissue located downstream of the upper annular surface by the delivered, positioned and expanded prosthetic mitral valve device.

Abstract: A highlighting system for use with electronic circuit design tools is provided for displaying signal waveforms and Register Transfer Logic (RTL) source code portions corresponding to a selected signal in the same window. The user selects a time and signal to be explored. Based on the selected time and signal, the values of all related signals are identified from a database generated by simulation of RTL source code. Nodes corresponding to the related signals are identified from a gate-level netlist corresponding to the RTL source code and the nodes responsible for the particular value of the selected signal at selected time are identified. The nodes are then mapped on to the RTL source code portions by a process of Instrumentation. The RTL source code portions so identified are then displayed. In particular, the portions of the RTL source code responsible for the particular value or transition in particular value of the signal at the selected time are highlighted.

Abstract: The present invention is used for guiding formal verification of a circuit design in circuit simulation software to optimize the time required for verification of a circuit design. The invention modifies the analysis region being used for verification in order to optimize the time for verification. The invention allows for manual, semi-automatic, and automatic modification of the analysis region. The modification is done by either expanding or reducing the analysis region or by adding new rules as assumptions to the existing analysis region. The invention also uses the concept of an articulation point for modification of the analysis region. The modification of the analysis region is performed in a manner to optimize time and memory required for verification of the circuit design.

Abstract: Methodology for verifying properties of a circuit model in context of given environmental constraints is disclosed. Verification of a specified property is performed by analyzing only a portion of the circuit model. The present methodology is also directed towards reducing the computation time for verifying the specified property. Further, the present methodology allows the connection of an additional circuit model to the circuit model in a non-intrusive manner. The connection is made without making any modifications to the description of the circuit model. This permits the straightforward specification of related environmental constraints and properties, which makes it possible to verify correct behavior of complex interfaces.

Abstract: This invention determines whether two circuit models have equivalent functionality. The method allows very fast comparison between two circuits taking advantage of previous work done. Whenever an apparatus associated with the method solves a problem, it stores information that learned during the solution of the problem, in a database. If the apparatus is presented with a new problem of determining equivalence between two portions of two circuits, it checks if it has seen sub-circuits similar to either of the two pieces before. If it has, it uses the knowledge cached during the previous checks to make the new check easier. Checking equivalence of two circuit models involves checking equivalence of many pairs of sub-parts. Even when the subsequent comparisons involve different circuits, it is possible to take advantage of the information acquired during previous equivalence checks.

Abstract: This invention determines whether two logic level circuit models have equivalent functionality. The method allows difficult portions of the equivalent functionality check to be partitioned and concurrently solved in a distributed computing environment. This permits the user to use, in a scalable fashion, additional computing resources to rapidly solve difficult equivalent functionality checks. The method allows difficult checks to be solved using (1) a divide-and-conquer approach, (2) by a competitive approach in which many independent attempts are made to solve the same check, or (3) by allocating more resources to solve the difficult check.
