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.

University of South Florida and Charles Stark Draper Laboratory | Date: 2016-11-28

An electronic catheter stethoscope measures and analyzes acoustic fields and dynamic pressure variations in the gaseous or liquid fluid inside a conventional medical catheter that is positioned in a patients urologic, digestive, reproductive, cardiovascular, neurological or pulmonary system. Measurement transducers are installed in a housing connectable to multiple preselected medical catheters. The transducers detect bodily functions that are transmitted to the preselected catheter from within the body. The transducers, housing, electrical interface and signal processing electronics are positioned outside the body.

Methods and apparatus are disclosed for interfacing with nerve fibers, such as axons. Embodiments provide multiple micro-channels, into which individual fascicles of a nerve may be placed, one fascicle per micro-channel. Each micro-channel has an associated set of micro-wire electrodes that penetrate the fascicle in the micro-channel. The micro-wire electrodes are thinner than prior art photolithographed micro-electrode arrays. Consequently, more micro-wire electrodes may interface with a single fascicle, and each micro-wire electrode interfaces with fewer axons, than in the prior art. Multiple rows of micro-channels may be stacked to construct two-dimensional arrays of micro-channels. These embodiments thereby facilitate finer motor control in prosthetic devices, and more granular sensory feedback from prosthetic devices to central nervous systems, than is achievable in the prior art.

Wires, such as microwires or nanowires are braided, woven or twisted by attaching an end piece to a first end of a plurality of wires, wherein the end piece has a response to an electromagnetic or fluidic work force different than that of the wire. The end pieces are manipulated relative to each other by selective application of electromagnetic or fluidic force that braids, weaves or twist the wires at the first end, while the second ends of each of the wires remain fixed relative to each other.


According to one aspect, embodiments of the invention provide a CDC simulation system comprising a timing analysis module configured to receive a circuit design, analyze the circuit design to identify at least one CDC, and generate a report including information related to the at least one CDC, a CDC simulation module configured to communicate with the timing analysis module and to receive the report from the timing analysis module, and a test bench module configured to communicate with the CDC simulation module, to receive the circuit design, and to operate a test bench code to simulate the operation of the circuit design, wherein the CDC simulation module is further configured to edit a top level of the test bench code, based on the received report, such that the test bench module is configured to identify timing violations in the circuit design due to the at least one CDC.

The systems and methods disclosed herein are generally related to a cell culture system. More particularly, the systems and methods enable the culturing and interconnecting of a plurality of tissue types in a biomimetic environment. By culturing organ specific tissue types within a biomimetic environment and interconnecting each of the organ systems in a physiologically meaningful way, experiments can be conducted on in vitro cells that substantially mimic the responses of in vivo cell populations. In some implementations, the organ systems are fluidically connected with a constant-volume pump.

Systems and methods for determining the shape and/or position of an object are described. A fiber optic shape sensor (FOSS) may be used in combination with one or more inertial measurement units (IMUs) to mutually cross-correct for errors in the sensors measurements of position and/or orientation. The IMU(s) may be attached to the FOSSs optical fiber, such that each IMU measures the orientation of a corresponding portion of the optical fiber. The position and shape of the optical fiber can then be determined based on the measurements obtained from the IMU(s) and the measurements obtained from the FOSS. For example, the FOSS measurements and the IMU measurements can be provided to a state estimation unit (e.g., a Kalman filter), which can estimate the position and/or shape of the optical fiber based on those measurements. In some embodiments, the estimates of position are used for navigation of tethered mobile devices.

A new approach for rapid slew and settle of small satellites is based on four single degree-of-freedom control moment gyroscopes with variable speed flywheels (or reaction wheels) in a pyramid configuration, combined with path and endpoint constraint time-optimal control. The path and endpoint constrained time-optimal control can be augmented with momentum management without the use of additional actuators.

Methods and systems are disclosed for obtaining and analyzing information to determine an estimated state of a real world. First information is obtained from a first source of a plurality of sources (e.g., data stores, real-time data streams, or information services), where the first information is potentially indicative of first and second states of the real world. If the first information exceeds a first decision threshold, then the estimated state is the first state, and if the first information exceeds a second decision threshold, then the estimated state is the second state. If the first information does not exceed either of the first and second decision thresholds, then second information is obtained from a second source. Obtaining the second information is based on whether the second source includes information that is relevant to the estimated state and whether the second source includes information that is redundant with the first information.

A compact hydraulic manifold for transporting shear sensitive fluids is provided. A channel network can include a trunk and branch architecture coupled to a bifurcation architecture. Features such as tapered channel walls, curvatures and angles of channels, and zones of low fluid pressure can be used to reduce the size while maintaining wall shear rates within a narrow range. A hydraulic manifold can be coupled to a series of microfluidic layers to construct a compact microfluidic device.

A chip scale star tracker that couples starlight into a lightguide such that the angle of incidence partially determines the mode of propagation of the starlight in the lightguide. A baffle system integrated with the lightguide prevents propagation of light incident from a predetermined range of angles.
