Drone Detection and Tracking by Acoustic Signature (D2TAS)

Project number
24048
Organization
Raytheon Technologies
Academic year
2023-2024
Small commercial drones equipped with cameras and/or other potentially lethal payloads are a persistent challenge for our DOD and national security organizations. These drones are difficult to see or hear until they are already in the effective threat perimeter. There is a need for a standoff detection and tracking capability to spot these potential threats at an actionable distance before they represent a tactical threat to military or high value government personnel.
The “D2TAS” system would allow security forces to detect and track small UAS that pose a potential threat to military and government personnel.

This system will be portable, and will be able to detect various sizes of quad copter or octo-copters at a slant distance of 100m to 500m or beyond. The system should be able to provide an azimuth and elevation value as to where the drone threat is located and also track the movement of the one drone.

Aerospace Radome Impingement Testing

Project number
24046
Organization
Raytheon Technologies
Academic year
2023-2024
Overview
Aerospace industry employs sensitive and expensive instrumentation and radars for sensing, navigation and tracking on all forms of aircraft. This equipment is protected by special Radomes of various polymers, composites, ceramics and alloys to protect sensitive instrumentation from impingement from precipitation, insects and airborne foul at a variety of speeds from low speed to Mach 1+.

Need Statement:
The development and customization of these radomes requires special testing to qualify the durability and survivability of the different materials and shape configurations. There needs to be a test method of creating a controlled impingement event that can be used to validate the radomes designs for their specific applications.

Solution:
Review test need specifications and develop a test method approach. Develop a modular, configurable, and programmable test apparatus that will enable the controlled impingement (kinematic characteristics) of a unique plastic bead (weight, strength), at a specific speed (low speed 200kts to medium speed 800kts) against representative radomes samples. This system will need to be able to measure the bead physical characteristics prior, measure the velocity of the beads just prior to impact, and provide a method of inspection or assessment for survivability scoring.

BOTCOM - Satellite Communication System for Autonomous Aquatic Drones for Ocean Health

Project number
24043
Organization
ACABI
Academic year
2023-2024
The purpose of this project to develop a satellite-based communication and control system for a swarm or fleet of autonomous water/ocean drones known as “Aquabots.” The chosen method for communication with a master vessel will be via satellite, this will be required to be reliable and cost effective, in particular with regard to data transfer.

Specifications – two-way satellite communications with lead vessel, command data transmission, acquired data transmission, error and diagnostic transmission, distress transmission. System to have low power consumption 1ah @ 12v. System to have recording and display capabilities.

Requirements: (1) Research into types of robotic inter-communication systems available. (2) Identify how these systems can be adopted or improved (3) Identify low-cost sensing/communication systems for collision avoidance (4) Demonstrate system operation through prototyping and testing of an existing Aquabot prototype

Background, Rationale and Project Scope:
The health of the ocean is critical for overall earth and human health. Of concern is the increasing stress being placed on the world’s oceans, and for that matter other bodies of water including lakes and rivers. Increasing pollution from runoff and population growth; the increased release/dumping of pollutants, petrochemicals and garbage; lack of recyclability of plastics with generation of dispersed microplastics; and the list goes on - all are collectively and exponentially affecting ocean/water health. The relentless increase of ocean waste is at risk for impacting the health not only of the oceans but also those organisms who rely directly or indirectly on the sea. Climate change, as well, is a further stressor leading to an increase in sea level, a decrease in salinity, regional oxygen depletion and alteration of sea life - from the microscopic on up.

AquaBot drones are being developed to monitor the state of the oceans, obtain regional samples (salinity, pH, Temp) and recover plastic and other contaminating materials from the oceans. To increase the efficiency of these devices it is intended that they will operate in a swarm or fleet mode. To work in this manner individual drones need to be able to communicate with each other and take directions from a central command control. The vessels (drones) should use an Automated Identification System protocol (AIS) to transmit their position and be able to monitor each other’s position. Key control parameters are collision avoidance, search pattern adherence, vessel integrity/health, sensor data communication, error reporting, diagnostics and maintenance reporting.

The Wired Room 2.0 – Automated Digital Sound, Image and Motion Analysis for Enhanced Medical Diagnostics from A Patient Encounter

Project number
24042
Organization
Kidney ADVANCE Project - NIH/ACABI
Academic year
2023-2024
This project will develop a “Smart Room” for patient examination able to capture much of this lost information. The project will benefit from and build upon work done by a Sr. Design team in ‘22-‘23. A kit will be designed that is portable, able to be placed in any given space utilized for patient examination. The kit will consist of: 1. Cameras (2-4) for image and motion capture; 2. microphones (2-4) for sound capture; 3. a handheld microphone for close patient examination (e.g. convertible or integrated with a stethoscope); 4. a handheld camera for close examination; and 5. a handheld microscope for extreme close-up image capture. Central to the kit will be an interface able to input all of these sources, and a computer system with large graphic display able to portray all inputs. The sophistication of the system will be in developed algorithms - i.e. in the systems’ ability to measure specific parameters from the input captured signals and display the processed time-synched information. Parameters to be measured include: accurate dimensions of a body part, accurate movement analysis (the system will incorporate MOCA - a system recently developed allowing image and motion quantitation (see Applied Sciences, 12(12), 6173. https://doi.org/10.3390/app12126173; sounds – including speech, breathing, heart sounds, AV graft/fistula sounds – analyzing them as to frequency, amplitude, pitch, phase and other subtle metadata including HNR (harmonic to noise ratio), NHR (noise to harmonic ratio), energy entropy (EE), short time energy (STE), zero crossing rate (ZCR), spectral roll off (SR), spectral centroid (SC) and spectral flux (SF) to estimate stress related acoustic high level features such as jitter and shimmer. Patient vital signs and weight will also be measured and inputted. Processed data needs to be able to be displayed as well as be compressed and stored in a fashion that may be incorporated in the electronic health record for ready serial access and display of evolving trends

The long-term goal and hope here it that from additional patient quantitative data gathered by the wired room, that new “digital biomarkers” may emerge stemming from serial evaluation of parameters measured over time. These new biomarkers will ultimately enhance the precision of clinical care.

Project Background/Scope: The role of the health care encounter – whether it be at the medical office, clinic, hospital, home or field is critical in obtaining relevant information to guide and direct the delivery and accuracy of care. Studies have demonstrated that more than 70% of diagnoses and advancement of care emanates from the physician or health worker carefully questioning and observing the patient. Sadly, patient encounters today have become shorter as to time spent, with the physician often hampered in examination focus by requirements of electronic health record (HER) data entry and use of a computer. Studies have also shown that many correct diagnoses are made by the doctor using information, such as: what and in what way the patient speaks, how the patient looks and acts, how the patient behaves, how the patient sits, how the patient walks, how the patient smells, and other information gained by focused attentive one–on–one patient encounters and consultations. In routine doctor-patient interactions today much of this information is not recorded and is lost.

Vibroshear: A System for High-Throughput Drug Discovery of Agents Limiting Shear-Mediated Cell (Platelet) Activation

Project number
24041
Organization
Kidney ADVANCE Project - NIH/ACABI
Academic year
2023-2024
Project Goal: To design and build a system for high throughput drug screening of agents capable of limiting shear-mediated cell (platelet) activation. The heart of the system is a “multiwell plate unit,” with contained means for exposing fluid and cells within each well to defined shear stress. The shear mechanisms to be considered in design include: 1. magnetically activatable beads 2. focused ultrasound or 3. vibration/acoustics, all inducing defined, predictable shear stress to fluid contained in each well. The utility and value of this system will be to systematically, in large scale, uniformly shear-activate platelets placed in each well, either with or without test compounds. The system will be utilized for screening of new agents able to limit shear-mediated platelet activation. The multiwell plate unit, once shear studies are complete, will be “run” in a multiwell plate reader for readout. The system will interface with a multiwell dispenser for compound loading. The system wil have an output data collection and display module for recording and displaying +compound hits from the plate reader output.

Project Background/Scope: Thrombosis or “blood clot formation” is a major limitation of implantable cardiovascular therapeutic devices (CTDs) such as ventricular assist devices (VADs), prosthetic heart valves and stents. Thrombosis is also an issue and complication for patients having implanted shunts and fistulas as occurs in renal failure for those on dialysis. Central to blood clot formation is the platelet. Platelets become activated in passing through CTDs via exposure to excessive shear forces imparted to flowing blood through the fluid paths of these devices. To limit clot formation, currently patients are prescribed a range of anti-platelet drugs aimed at limiting platelet activation. In recent years the Slepian lab has been repeatedly demonstrated that no current anti-platelet drugs in routine clinical use block shear-mediated platelet activation! – these drugs were developed for biochemical activation means, not mechanical means as occurs with shear! As such a major gap in clinical therapy for patients implanted with CTDs are effective drugs able to limit the activation of platelets due to shear, rather than biochemical stimulation. Developing a system and tool as outlined here will jumpstart and accelerate new drug discovery via high-throughput screening.

Model Based Electrical Diagram and TID Generation

Project number
24040
Organization
Northrop Grumman
Academic year
2023-2024
Northrop Grumman Corporation (NGC) is looking to build a software tool using model based interconnected elements that can then be exported to multiple formats.

When initially designing a vehicle Electrical Ground Support Equipment (EGSE) rack, our Electrical Engineers (EEs) typically must create drawings, then map those drawings to tables within a Technical Interface Document (TID), and then software engineers must take the TID and replicate the interconnections within a configuration file. With all these hand-offs, we typically run into inconsistencies between each step that are not found until later in vehicle development, which is undesirable.
The idea of this project is to create model-based interconnect tool that defines inputs, outputs, and other special properties of a component. The tool can then export the interconnected model into a minimum of these two views:
• Electrical drawing diagram showing the interconnected components with proper labeling.
• TID table generation

If time allows, then a bonus would be able to generate components of the config file.

Each model would be of a single component found within a EGSE rack such as a power supply, PC, and discrete I/Os.

This tool will allow a single source of truth which defines each of the outputs needed for a launch vehicle for the EGSE and its configuration between components.
