ABSTRACT:Cognitive skills/capabilities are important for the military personnel to fulfill tasks and to ensure mission efficiency and success. In the past decade, there are abundant researches suggesting that non-invasive brain stimulation via transcranial direct current stimulation (tDCS) holds great promise to enhance a soldier's cognitive performances. Although models to predict the tDCS current flow exist, they need to be validated using a high-fidelity head phantom which can mimic both its complex shapes/configurations and the conductivities of various tissues. Such a phantom, however, is currently lacking. In this proposal, AlphaSense, Inc. collaborates with Harvard Medical School to develop a novel 3D- printed head phantom for tDCS model validation. If successful, the merits of the proposed head phantom and its fabrication method include the following: a) High accuracy for tDCS model validation, b) Fully automatic process for tDCS parameter optimization, c) Capable of generating both generic and subject-specific phantoms, d) Excellent long-term stability, and e) Low fabrication cost.BENEFIT:The outcome of this research is coupled to a very clear commercialization path. The proposed head phantom can be used for both military and civilian applications. The most straightforward military application is to valid various tDCS models, based on which effective therapeutic treatment procedures can be obtained. Consequently, the cognitive performances and learning skills of soldiers and military personnel can be substantially improved to enable mission success. In addition to the cognitive performance enhancement, the tDCS model may also help the researchers to identify therapeutic treatment solutions for the veteran and active-duty solider depression issues. For civilian applications, the proposed phantom can also be used by medical researchers to identify optimum tDCS procedures to treat various medical conditions, including brain injuries, strokes, memory loss, and depression. It should be noted that the proposed 3D printing method is by no means limited to fabricate the phantoms for the tDCS model validation. If successful, it also provides a generic solution to fabricate a wide variety of medical phantoms, including brain, breast and heart phantoms, etc. for various training and surgical treatment planning applications. The potential market is huge for the above-mentioned medical phantoms.

Gradient metal alloy structures possess multi-functional properties that conventional monolithic metal counterparts do not have. Such structures can potentially change the paradigm of material selections and mechanical designs to enable more efficient space vehicles to be built. Existing laser-based additive manufacturing techniques for gradient metal alloy fabrication suffer from the following two major drawbacks: high system cost and slow printing speed. In this proposal, AlphaSense details the development of a novel 3D printer for the fabrications of gradient metal alloy structures. Key innovations of this proposal include the following: a) The fabrication of gradient metal alloy parts using low-cost resin as starting materials, b) The development of novel printing slurries containing micro-/nano- sized metal particles and photo-curable resins to fabricate the green parts, and c) The application of a Digital Light Processing (DLP) projector for simultaneous layer exposure. With such innovations, the merits of the proposed 3D printing method for metal part fabrication include the following: a) Low fabrication cost, b) High printing speed, c) Superior printing quality, d) Easy to scale up and e) Easy and well-controlled process.

An optical particle counter determines the velocity of particles passing through a particle detection zone, and thereby the velocity of gas flow, from both the measured time of flight of discrete particles and also the size of intensity peaks of scattered light. This is used to determine particle concentration and may be used to control an optional fan.


An amperometric electrochemical gas sensing apparatus for sensing NO_(2) and O_(3) in a sample gas and a method of using same. The apparatus comprises: a first working electrode which is a carbon electrode and at which both NO_(2) and O_(3) are reducible to thereby generate a current; a second working electrode which is a carbon electrode and at which NO_(2) is reducible to thereby generate a current; and an O_(3) filter adjacent the second working electrode, and said apparatus is configured such that, in operation, the first working electrode and the O_(3) filter are exposed to the sample gas in parallel.

Due to their high specific strength and light weight properties, polymer matrix composites (PMCs) are increasingly used in a wide variety of military and civilian aircrafts. The mechanical strength of PMCs can be dramatically compromised when such materials are exposed to various heat sources during operation and maintenance. It has been shown that PMCs can lose up to 80% of their mechanical strength when exposed to aggressive environment without causing any defective signs, which can be either visually examined or detected with conventional non-destructive evaluation (NDE) technique. In this SBIR project, AlphaSense aimed at developing a novel handheld NDE sensor to detect and quantify incipient heat damages in composite airframe structures. In Phase I, we have successfully proven the feasibility. Phase II will focus on sensor performance improvement, identification of potential confounding factors and elimination techniques, and field- deployable sensor prototype implementation and testing.
