An idea of embedding RFID tags on tactile paving as indoor positioning system to tell current location, direction and distance to destination through mobile app for visually impaired is proposed.
Tactile paving, a footpath with distinctive surface pattern, assists visually impaired people to walk and stop safely. Yet, it doesn’t tell which direction the path goes. For example, let assume Figure 1 is Manhattan Subway Station. Which side is a stop for a train to Brooklyn (? or ?)? Which direction (? or ?) should follow to go to the Exit to Broadway? Where path ? goes?
To solve ...
Composites prosthetics are defined by predefined stiffness of the material and the perception of the composite deformation for the same product is different from one person to another. For this reason, a inflatable composite cover is attached under the prosthetic foot . The role of the cover is to modulate the shock damping but also to increase the contact surface. A big problem in composite prosthetic like the leaf springs for example is that the contact with the sole is never perfect planar, that means an increase in torsion tensions and regional impact cracks. The inflatable composite cover reduce ...
Did you experience feet pain after walking for a period? And you just simply accept as you think that is normal?
Here to share you instrumented footwear that enables real-time monitoring and addressing unhealthy walking pattern (abnormal gait) by giving tactile feedback to the user.
It is low cost, light weight and fixed to a variety of typical adult foot size, easy to wear and data can be continuously collected wireless over few hours. Made up of three inertial sensors which positioned at dorsal surface of foot, ankle and heel that linked tactile feedback system that installed in designed ...
Transcranial Magnetic Stimulation (TMS) is a non-invasive therapeutic technique that uses a magnetic pulsed field emanating from coil windings to induce neural action potentials in the brain to address a variety of neurological and physiological applications.
TMS therapy, which has been FDA approved for treatment of major depressive disorder (MDD), holds promise for a wide range of disease states including, Schizophrenia, Parkinson, Tourette’s Syndrome, Alzheimer’s, Obesity, Bipolar Disorder, anxiety disorders, etc.
Current TMS devices lack in several principal areas preventing optimal application or, in many cases, rendering treatment ineffective. As well, the operational constraints associated with ...
The IVEA is a brand new piece of medical equipment unlike any other product in the healthcare market. Launched at the American Organization of Nurse Executives Conference in April this year, its transformative design subsequently earned the Silver Medal for the 2015 Edison Awards.
The IVEA was born from real clinical experience, and from seeing the problems of patient care firsthand. Firefly Medical worked extensively with clinicians to identify the right design, one that was intuitive, functional, and elegant. In effect, the IVEA was designed by nurses for nurses, becoming an affordable solution that bridges the gap between how ...
The Jala pampa is a water pump
that filters 99. 9 % of
the bacteria in water.
It does this with a ceramic
filter that is located
inside the perforated tube.
The pumping mechanism
ensures fast and especially
safe drinking water.
The pump can be used with
any water source,
It is able to pump
because of its two
'one way valves'.
One pressure valve
and one suction ...
For over a half-a-century, back surgeons have been cutting spinal disk cartilage and bone with Kerrison Rongeurs, whose original design for widening safely a cranial perforation was modified so that in spinal incisions, the tip could be introduced into ever-smaller spaces.
In such spaces where blood accumulates, jaws close on the target tissue but at the same time unavoidably blood seeps into the jaws as they are closing.
Over the past twenty years or so as the concern for contaminated instruments has drawn attention, manufacturers of this type of instrument have been busy conceiving of ways to make sure ...
The major disadvantage of most chemotherapeutic approaches to cancer treatment is that most are non-specific which results in the well-known side effects. Magnetic drug targeting offers a major advantage through targeting a specific site, such as a tumor. Magnetic drug targeting is a drug delivery approach in which drugs are added to magnetizable particles and then magnetic fields are applied to concentrate them at disease locations such as tumors. Magnetic drug targeting allows the drug dosage to be increased significantly while avoiding side effects in healthy tissues. However, the current studies focused on approaches that require bulky magnetic resonance ...
Traditional TURP surgery (Transurethral Resection of the Prostate) for BPH (Benign Prostatic Hyperplasia) removes excess prostate tissue using a heated wire loop with side effects such as death (1%), incontinence (3%), impotence (5%) and retrograde ejaculation (75%). Alternative techniques using lasers use $1,000 disposable fibers but offer greatly reduced incidence of side effects.
Most laser surgery for BPH uses a side firing optical fiber because the tissue masses (prostate gland lobes) surround the urethra through which the fiber gains access. Compared to standard axial delivery fibers, side-fire fibers produce highly divergent and distorted output profiles with up to 35% ...
Development of a wireless capsule endoscope is a growing research area because it could be easily swallowed by patients to capture images of the digestive system without pain. But a drawback of the current capsule endoscope is mainly passive-motion-type-endoscope. To overcome this drawback, a maneuverable capsule endoscope (MCE) based on a gimbaled ducted-fan (GDF) system is proposed by presenting a system design, a prototype development of the GDF system, and associated modeling & simulation.
The concept of the GDF is adopted from the thrust-vector control algorithm of a space shuttle. To prevent organ damage, the ducted fan, which generates ...
