Abstract: A method for determining motional branch current in an ultrasonic transducer of an ultrasonic surgical device over multiple frequencies of a transducer drive signal. The method may comprise, at each of a plurality of frequencies of the transducer drive signal, oversampling a current and voltage of the transducer drive signal, receiving, by a processor, the current and voltage samples, and determining, by the processor, the motional branch current based on the current and voltage samples, a static capacitance of the ultrasonic transducer and the frequency of the transducer drive signal.

Abstract: A system and method for permitting entry into a defined operational mode of a software application on a selective basis. To enter the limited-access mode, action must be taken at both a server and a client device. The client device stores a software application that is configured with inactive functionality for entering the predefined mode in response to user input. The server is operable to provide very limited distribution of configuration settings data to activate the functionality for recognizing predefined user input and responsively entering the predefined mode. The required predefined user input is a widely-kept secret to which access is extremely limited, and is identified to users only an as-needed basis. Accordingly, access to the defined mode is limited to users (i) having a computing device that has received the configuration settings data enabling recognition of the predefined user input, and (ii) knowing and providing the predefined user input.

Abstract: A normalization engine, system and method provide normalization of and access to data between heterogeneous data sources and heterogeneous computing devices. The engine includes connectors for heterogeneous data sources, and conduits for gathering a customized subset of data from the data sources, as required by a software application with which the conduit is compatible. Working together, the connector and conduit may gather large amounts of data from multiple data sources and prepare a subset of the data that includes only that data required by the application, which is particularly advantageous for mobile computing devices. Further, the conduit may process the subset data in various formats to provide normalized data in a single format, such as a JSON-formatted REST web service communication compatible with heterogeneous devices. As an intermediary, the normalization engine may further provide caching, authentication, discovery and targeted advertising to mobile computing and other computing devices.
