Draper Laboratory is an American not-for-profit research and development organization, headquartered in Cambridge, Massachusetts; its official name is "The Charles Stark Draper Laboratory, Inc". The laboratory specializes in the design, development, and deployment of advanced technology solutions to problems in national security, space exploration, health care and energy.The laboratory was founded in 1932 by Charles Stark Draper at the Massachusetts Institute of Technology to develop aeronautical instrumentation, and came to be called the "MIT Instrumentation Laboratory". It was renamed for its founder in 1970 and separated from MIT in 1973 to become an independent, non-profit organization.The expertise of the laboratory staff includes the areas of guidance, navigation, and control technologies and systems; fault-tolerant computing; advanced algorithms and software solutions; modeling and simulation; and microelectromechanical systems and multichip module technology.

Patent
Charles Stark Draper Laboratory | Date: 2017-03-01

The present disclosure describes a blood oxygenator that includes a checkerboard layout of fluid (e.g., blood) and gas (e.g., oxygen) channels. When viewed as a cross-section through each of the channels of the oxygenator, the checkerboard configuration includes alternating gas and fluid channels in both the x-axis (e.g., in-plane) and in the y-axis (e.g., out-of-plane) directions. The oxygenator described herein reduces manufacturing complexity by using first, second, and third polymer layers that include asymmetrical channel designs. The channel designs include open gas channels, which are exposed to the ambient atmosphere. The oxygenator is placed within a pressure vessel to drive gas into each of the open gas channels, which in some implementations, negates the need for a gas manifold.

Patent
Charles Stark Draper Laboratory | Date: 2017-04-19

Systems, methods, and computer program products are provided for identifying software files, flaws in code, and program fragments by obtaining a software file, determining a plurality of artifacts, accessing a database which stores a plurality of reference artifacts for reference software files, comparing at least one of the artifacts to at least one of the reference artifacts stored in the database, and identifying the software file by identifying the reference software file having the reference artifacts that correspond to the plurality of artifacts. Certain embodiments can also automatically provide updated versions of files, patches to be applied, or repaired blocks of code to replace flawed blocks. Example embodiments can accept a wide variety of file types, including source code and binary files and can analyze source code or convert files to an intermediate representation (IR) and analyze the IR.

Systems, methods, and computer program products are provided for locating design patterns in software. An example method includes accessing a database having multiple artifacts corresponding to multiple software, and identifying a design pattern for at least one of the software files by automatically analyzing at least one of the artifacts associated with the software. Additional embodiments also provide for storing an identifier for the design pattern for the software in the database. For certain example embodiments, the artifacts include developmental, which may be searched for a string that denotes a design pattern, such as flaw, feature, or repair. Additional example embodiments also include finding in the software file a program fragment that implements the design pattern.

Systems, methods, and computer program products are shown for providing a corpus. An example embodiment includes automatically obtaining a plurality of software files, determining a plurality of artifacts for each of the plurality of software files, and storing the plurality of artifacts for each of the plurality of software files in a database. Additional embodiments determine some of the artifacts for each of the software files by converting each of the software files into an intermediate representation and determining at least some of the artifacts from the intermediate representation for each of the software files. Certain example embodiments determine at least some of the artifacts for each of the software files by extracting a string of characters from each of the plurality of software files. The software files can be in a source code or a binary format.

Techniques are described for metadata processing that can be used to encode an arbitrary number of security policies for code running on a processor. Metadata may be added to every word in the system and a metadata processing unit may be used that works in parallel with data flow to enforce an arbitrary set of policies. In one aspect, the metadata may be characterized as unbounded and software programmable to be applicable to a wide range of metadata processing policies. Techniques and policies have a wide range of uses including, for example, safety, security, and synchronization. Additionally, described are aspects and techniques in connection with metadata processing in an embodiment based on the RISC-V architecture.

The present disclosure describes systems and methods for mimicking body tissue and the function thereof. The mimicked body tissue can include kidney tissue, the blood brain barrier, and other tissues. In some implementations, the systems described herein are used to test the impact of controlled factors on the tissue. The controlled factors can include flow rates, shear rates, and test chemicals (e.g., therapeutics and toxins). In some implementations, the system and methods are used to test pharmaceutical and biological therapies, characterize healthy or diseased tissue, and observe phenomena of the tissue in vitro.

Defects in ferromagnetic materials are detected and characterized by analyzing the items magnetic fields to find portions of the magnetic fields that differ in characteristic ways from residual magnetic fields generated by non-defective portions of the items. The portions of the magnetic fields that differ in the characteristic ways correspond to locations of the defects. The residual magnetic fields correspond to portions of the items distant from the defects. The defect characterization may include volume of material lost due to each defect and/or width and/or depth of each defect.


Patent

A method for observing a subterranean reservoir penetrated by a production well and two or more injection wells. A first set of magnetic tracer particles is delivered to the reservoir by one injection well, while a second set of magnetic tracer particles is delivered to the reservoir via a second injection well. The first set of tracer particles includes a first identification element while the second set of tracer particles includes a second identification element. The presence or absence of particles from the first set or second set of tracer particles in fluid produced from the production well is determined by X-ray fluorescence spectroscopy or another analogous technique using the identification elements in the production fluid. The tracer particles are concentrated in the production fluid by magnetic extraction. The fluid flow (or absence thereof) from a particular injection well to the production well can thus be determined.
