Power-Assist Control Interface for Wheelchairs

This technology monitors input and effort, and instantly adapts the device to real-world conditions.A computer-controlled, programmable control interface allows safe, intuitive manual control for motorized wheelchairs that operate in variable terrain. The key feature of this technology is its proprietary computer program that enables an operator to manage a load as if it were light and on a smooth level surface, no matter what the real-world load or grade is. Operation is completely intuitive and does not require manipulation of throttle and/or brakes.

Neuroprosthetics and Solutions for Restoring Sensorimotor Functions

A new class of prosthetic devices looks, feels, and functions like natural limbs.Advances in body armor and life-saving technology have increased survival rates of severely injured military personnel. Unfortunately, the survivors of improvised explosive devices are often left with amputations and/or spinal cord injuries. The increase in amputations and paralysis among military personnel requires significant advances in prosthetics and functional electrical stimulation (FES) systems so that the soldiers can return to the field or to productive civilian lives.

Implantable Microsystems for Anatomical Rewiring of Brain Circuitry

This implantable device technology improves long-term functional recovery after a traumatic brain injury.It has been demonstrated that after a stroke-like lesion in the cerebral cortex of non-human primates, the remaining intact tissue undergoes extensive neuro-physiological and neuroanatomical remodeling. The ability of cortical areas remote from the infarct to form new cortico-cortical connections over long distances between the frontal and parietal lobes has been demonstrated. It is likely that these novel connections play a role in functional recovery after cortical injury.

Use of Recombinant Factor VIIa for Control of Combat-Related Hemorrhage

Recombinant rFVIIa may have a damage-control role, quickly arresting blood loss until the casualty can be evacuated to a hospital.Blood loss is a major cause of death among combat casualties, accounting for nearly half of all deaths on the battlefield. The great majority of these deaths is due to intracavitary hemorrhage that cannot be controlled by traditional methods such as tourniquets or pressure dressings. Surgery remains the best method for controlling this type of hemorrhage and preventing death, although methods are needed to control bleeding until patients can get surgical intervention.

Biotic-Abiotic Interface Between the Body and an Artificial Limb

A modified titanium construct and specially machined surface increase adherence of tissue to a prosthetic limb.Because of its high mechanical properties, chemical stability, and biocompatibility, titanium is a commonly used material in dental and orthopedic applications. Its excellent biocompatibility allows titanium implants to be directly anchored to bone, or osseo-integrated. The conventional prosthetic replacement in amputees is a stump-socket design, which transfers forces through the prosthetic to an external contact point on the patient. Such a design results in non-uniform distribution of pressure, and can lead to pain, infection, and necrosis of the soft tissues at the point of contact.

RF Device for Acquiring Images of the Human Body

This portable, simple system using a ring-shaped antenna array and planar circuit technology can serve as security in airports, mass transit locations, and power plants.A safe, non-invasive method for forming images through clothing of large groups of people, in order to search for concealed weapons either made of metal or not, has been developed. A millimeter wavelength scanner designed in a unique, ring-shaped configuration can obtain a full 360° image of the body with a resolution of less than a millimeter in only a few seconds. Millimeter waves readily penetrate normal clothing, but are highly reflected by the human body and concealed objects. Millimeter wave signals are non-ionizing and are harmless to human tissues when used at low power levels.

Controlling Devices Using the Ear as an Output Source

This method creates a hands-free way of controlling devices such as medical equipment, wheelchairs, computers, and cell phones.Current methods of device control include joysticks, which involve using one or both hands, external microphones that are cumbersome and pick up ambient noise, and external arrays that are also cumbersome and can restrict a user’s movement. Additionally, the external microphone and array options do not provide a high level of accuracy in certain situations.
