Engaging stakeholders in the home medical device market

The Growing Home Medical Device Market – How Could It Impact Med Tech Stakeholders? 90% of patients prefer digital technology tools (such as mobile apps) over medication, per an October 2013 survey by Digitas Health. And, Semico Research's Aging in Place: The Internet of Things for the Golden Years forecasts that the home medical device market will reach $30 billion in revenues by 2017. Gain expert insight into engaging stakeholders of the growing home medical device market - including implications for manufacturers, intended device uses, end users, safety and essential performance, transformation requirements, mobile apps + more.

VINCENT Systems Prosthetics Give Patients A New Feel For Life

The human hand is a biomechanical marvel, but our hands are easy to take for granted because we depend on them all day long. People without all or part of their hands, however, know full well the value of what is missing as they struggle to perform even simple, everyday tasks.

The Stealth E-Bike: Challenges in Developing the First Fully Integrated Drive System for E-Bikes

The idea of a bike with pedal assistance is very old, dating back to 1860, when pedal assistance was thought of as a steam machine that would give power to the back wheel of a bike. In 1895, the first direct-drive hub motor was developed, which, as a concept, still remains today. In 1897, the first idea for a mid-drive system was born, but wasn’t quite a finished idea. In 1898, the idea was developed of a direct-drive motor that is concentric with a shaft that powers a rotor atop the rear tire to make a friction drive. As decades went on, other concepts for e-bikes were developed, using drive systems only in the front wheel or the back wheel. FAZUA is launching the future of e-bikes in 2015 with what the company calls the mid-drive 2.0. It’s a mid-drive system with an integrated gear reduction that is smaller, lighter, and integrated in the bike so the e-bike actually still looks and feels like a bike – because it actually still is a bike.

Detecting High Stress in Oral Interviews and Text Documents

Content of an interview or text is subjected to various levels of statistical analysis to determine if the person knows the truth and is communicating it. Ames Research Center, Moffett Field, California When a person is interviewed, some of the answers may be inaccurate, or even deceptive, because the person may have either incomplete information, is telling only part of the truth, or is fabricating a false answer, or a combination of all three. When the person is habitually making statements that are known to be false, or only partly true, emotional and/or intellectual conflicts often arise within them, and these conflicts may become manifest by inconsistencies in use of different parts of speech or in logical relationships between statements. These inconsistencies are more subtle than inconsistencies in factual statements, and identification of these inconsistencies is more difficult and less straightforward than identification of factual inconsistencies.

Predicting Heart Age Using Electrocardiography

Lyndon B. Johnson Space Center, Houston, Texas Knowledge of a patient’s cardiac age, or “heart age,” could prove useful to both patients and physicians for encouraging lifestyle changes that are potentially beneficial for cardiovascular health. This may be particularly true for patients who exhibit symptoms, but who test negative for cardiac pathology.

Prediction of Visual Acuity from Wavefront Aberrations

This automated vision test is accurate, simple, and fast. Ames Research Center, Moffett Field, California Visual acuity (clearness of vision) usually is measured by an eye doctor using an eye chart. It measures the smallest letters that can be reliably identified by the patient at a specified distance. The traditional test requires the patient to look and report which letters they see.

Mobility Augmentation System Using Switchable Spring Mechanisms

This system could be used by disabled persons and individuals in rehabilitation who require prosthetics. NASA’s Jet Propulsion Laboratory, Pasadena, California The disclosed device provides key elements to enabling compact exercise machines that overcome many of the disadvantages of the current spacesuit, as well as medical prosthetics and exoskeletons. The mechanism is based on switchable, curved, leaf, and torsion spring mechanisms that support the user joints and at the contact with the ground to enable high-speed, low-loss locomotion. The springs are primed with an actuator to counteract losses and recycle the user’s elastic energy in the locomotion. The mechanism is designed to be switchable and to allow for removing the springs from the structure for fine control. Adjustable hard-stops are embedded into each joint to prevent overextension and optimize the performance at each gait. The spring mechanisms are made from carbon fiber composites to reduce the weight of the system. The components of this mechanism can be structurally connected to each other via a mechanical clutch to form a symmetric lower-extremity system with a passive spring mechanism to reduce the requirement of the joints to dampen the impact forces and recycle some of the energy of walking and running.
