Abstract: A software development process may support a transition from unverifiable, legacy code to verifiable code that is provably correct by construction. A behavioral model may be developed for legacy software that includes various behavioral criteria. Then, source code implemented in a verifiable language may be verified using the behavioral model to perform verification. Once the source code is complete and verified, a new verified implementation may be compiled. The verified implementation may then be executed, along with the legacy software, to identify differences in behavior which are fed back into the behavioral model and subsequently into the new source code. This process may then be iterated with the verifiable code being deployable once behavioral differences are resolved.

Abstract: A document anonymization system transforms structured documents, such as security policies, that contain user-specific and other sensitive data, producing encoded logic problems in the format or language of one or more constraint solvers; the logic problems do not contain any of the sensitive data. The system may perform a one- or two-stage anonymization process: in a first stage, the electronic document is analyzed according to its document type to identify parameters likely to contain sensitive data, and the associated values are replaced with arbitrary values; in a second stage, after the anonymized electronic document is converted into logic formulae representing the data, the system performs replacements of string constants in the logic formulae with arbitrary strings to further anonymize the sensitive data.

Abstract: Described here is a device comprising a microfluidic chip and an acoustic transducer external to the microfluidic chip, wherein the microfluidic chip comprises a channel in communication with a microwell having a volume less than one microliter, and wherein the acoustic transducer is coupled to the microfluidic chip via a coupling medium.

Abstract: The invention is a chewing tobacco substitute made from natural leaves and additives which simulate the taste and consistency of chewing tobacco to which a nicotine compound is added. The invention allows those addicted to chewing tobacco to chew and receive nicotine without incurring the other harmful side effects of tobacco. In one embodiment of the invention the product is provided with varying levels of nicotine.

Abstract: A system and method comprising a reporting mechanism for outputting an HMTL and XML document from a collection of hierarchically maintained settings such as group policy object settings or resultant set of policy data. The reporting mechanism provides a substantially complete view of which settings are configured (enabled) in a given group policy object, or a view for a resultant set of policy (that is applied to a given SOM), along with the values of the settings. The markup language format enables viewing a flat representation of the settings, and printing, saving and/or transporting of the settings. XML schemas describe a valid representation of group policy settings, and a valid representation of resultant set of policy.

Abstract: A training instrument for use in teaching a trainee the proper use of a radioactivity measuring instrument includes a transmitter unit that is held and controlled by an instructor and further includes a receiver unit which is held and operated by the student and which simulates the radioactivity measuring instrument. The instructor selects a level of radioactivity to be measured by the student at a remote site, and that information is transmitted to the receiver unit in a moduated form that is not affected by atmospheric conditions or reflections from surrounding objects. Both the receiver and the transmitter include circuits that simulate the operation of a multirange meter. These circuits employ the most significant bits of a digital representation of the signal to determine which scale should be used, while the remaining digits indicate the magnitude of the signal as read on the selected scale.
