The objective of the proposed SBIR is the design and development of a small, lightweight tactile transducer which produces a vibratory stimulus above the sensory/recognition threshold of the skin. A novel transducer element, based on a miniature, laterally acting linear motor driving a skin… More

This Phase I SBIR proposed the development of technology that will lead to smaller, lighter and more efficient power amplifiers for driving the highly reactive loads presented by active sonar transducers. Compared to other amplifier components, existingdesigns employ physically large, high weight… More

DESCRIPTION (provided by applicant): Trauma is the major cause of mortality in individuals under 45 years of age. Failure to rapidly control hemorrhage leads to inadequate organ perfusion (shock) and is the major cause of death in these trauma victims. Accordingly, portable, non-surgical,… More

DESCRIPTION (provided by applicant): An estimated 3.75 billion drug administrations were made to patients in United States hospitals in 1998, of which approximately 10% received their medications through an enteral tube as liquids. This number is growing. Despite the availability of a vast drug… More

This Phase II SBIR proposes the development of technology that will lead to smaller, lighter and more cost effective power amplifiers for driving the highly reactive loads presented by active sonar transducers. Following EAI's Phase I effort, and takingadvantage of new developments in… More

DESCRIPTION (provided by applicant): An estimated 3.75 billion drug administrations were made to patients in United States hospitals in 1998, of which approximately 10% received their medications as liquids through an enteral feeding tube (EFT). This number is growing. Despite a vast drug… More

It is estimated that 10% of the soldiers killed on the battlefield bleed to death from extremity wounds. Failure to rapidly control hemorrhage leads to inadequate organ perfusion (shock) and death. Many of these lives can be saved by the prompt and effective use of a tourniquet. However, a subset… More

Real-time displacement measurement techniques are needed to acquire aerodynamic and structural system characteristics in flight. This proposal describes the development of a new type of position sensor which we have termed a Point Coupled Sensor (PCS). This sensor is able to detect the position of a… More

Traditionally, the sonar amplifier system has been viewed as the configuration of various independent disciplines; transduction, magnetic compensation and matching, power amplifiers and control. Clearly these disciplines cannot be regarded in isolation and there are significant advantages in… More

Spatial disorientation (SD) and the subsequent loss of situation awareness account for a significant percentage of fatal mishaps in aviation. SD typically occurs when visual references are compromised, and the pilot's vestibular and somatosensory (tactile) sensations no longer provide accurate… More

Studies have estimated that as many as 22% of soldiers serving on the frontline may be at risk of mTBI from blows to the head or shockwaves caused by explosions. mTBI or concussion is also often associated with sports injuries and civilian trauma, with an estimated 5.3 million Americans living with… More

SD typically occurs when visual references are compromised, and the pilot's vestibular and somatosensory (tactile) sensations no longer provide accurate… More

An immediate and definite need exists for a portable screening device to provide objective assessment of mild-Traumatic Brain Injury (mTBI) and assist in the discrimination between mTBI and Post Traumatic Stress Disorder (PTSD) diagnosis. This research addresses the development of a portable… More

Combat environments can subject personnel to extreme conditions, testing the limits of both their physical and cognitive abilities. The sense of touch offers a relatively untapped channel for communications on the battlefield, and tactile displays can be an effective communication modality even… More

Traumatic brain injury (TBI) occurs when physical trauma causes temporary or permanent neurological damage. In some cases, symptoms can continue and contribute to disability. Dizziness and vertigo are associated with nearly all reported studies of mTBI and are a significant and functionally limiting… More

Combat environments can subject personnel to extreme conditions, testing the limits of both their physical and cognitive abilities. Tactile displays offer a relatively untapped channel for dismounted warfighter navigation, and can be an effective communication modality even under situations where… More

An immediate and definite need exists for a portable diagnostic device for the assessment of cortical function, and diagnosis of mTBI. This proposal has as its aim the development of a portable device and testing protocol for the objective and quantitative diagnosis of acute mTBI suspects. mTBI is… More

This project develops an ambulatory remote operated Tactile Awareness Prompting (TAP) system to be used within educational and clinical environments for students who have social skills deficits. Individuals with autism spectrum disorders (ASD) exhibit deficits related to social initiations and… More

The sense of touch forms an intrinsic part of our real world experience and is naturally associated with physical exploration and contact. Virtual Training (VT) Systems have successfully trained the Warfighter for several years by immersing the participant in a realistic simulation of the actual… More

Combat environments can subject personnel to extreme conditions, testing the limits of both their physical and cognitive abilities. During the Phase I SBIR, EAI designed and demonstrated a proof-of-concept system that enables investigation of multisensory navigation and communication among… More
