Millions of endoscopy surgeries are performed each year in the US, with even more performed internationally. Endoscopy has advanced rapidly in the last twenty years. However, little progress has been made towards the development of a 3D endoscope system, even decades after they have been proposed in scientific literature. We postulate this is due to the inherent design tradeoffs required by stereoscopic 3D system, the most common 3D imaging modality. Specifically, stereoscopic endoscopes fail to deliver high quality images, lack quantitative depth information about the target, and have difficult delivering the same depth sensitivity as the human eye.

We solve this problem by implementing an entirely new depth sensing modality we call depth measurements through controlled aberrations. ...

To create a book paper with reflection emission corresponding to the eyes optimal adoption wavelengths and thus increase the contrast in between the printed material and the substrate. This means that people, especial elderly, will have increased reading possibility at advanced ages.

To transform the high frequency visible light and UV light to wavelength around 550nm and thus also reduce the hazardous blue light around 440 nm which will prevent macular degeneration(AMD) and thus development of ...

With 17.3 million deaths in 2008, cardiovascular diseases (CVD) are the leading causes of death and disability in the world, increasing tendency (source: WHO). This leads to the necessity of simple and cheap monitoring systems to spot cardiac pathologies and diseases already at an early stage.

Since several decades, electrocardiograms (ECG) are the first choice and the Gold standard for heart monitoring. An ECG shows the potential differences on the body surface caused by the cardiac activity. It can be used to draw conclusions about the heart rate, the heart condition and about pathological changes. Commonly adhesive electrodes are used, which have several disadvantages: They must be placed directly on the patient’s skin, which can lead to skin irritations, ...

A Disposable Pad For The Prevention And Treatment Of Decubitus

Background:

Socially and medically under the radar, the annual cost of treating decubitus, commonly known as “bedsores” or “pressure sores,” is estimated at eleven billion dollars in the US. Hospital administrators are acutely aware of both the monetary cost and the cost in pain and suffering.

Historically, fleece has been very effective. It is not, however, commensurate with current hospital practices.

Pro-offered Solution:

Presently, low cost and disposability are essential, in addition to functionality.

The treatment for bedsores is the same as for their prevention, save the addition of anti-septic salves and wound healing protocols/ procedures.

The six criteria, then, are: the circulation of air directly against the skin, ...

Is it possible to build a high power, portable and inexpensive x-ray machine?

Imagine a soldier falls and needs to be evacuated via helicopter to a base camp, or perhaps a horse falls during a race and presumably has a broken leg, how could anyone diagnose the damage without radiography equipment?

Though I've never personally been in any of these situations in my 18 years, it's not hard to imagine how useful such an x-ray machine would be. Currently x-ray machines are large, heavy, power hungry items which aren't very useful anywhere but a hospital setting.

While the coolidge tube certainly hasn't gotten better over the years, batteries, capacitors and semiconductors have improved to the point where making a compact, ...

Sleep disorders are simultaneously among the most common diseases and the least diagnosed. Symptoms range from low energy, irritability, and concentration difficulties to sleep attacks, cardiac arrhythmias, and hallucinations. Considering the USA, more than 70 million people possibly have a sleep disorder, and a National Science Foundation’s poll found nearly half “rarely or never get a good night’s sleep on weeknights” and upwards of 20% are “sleepy.” Aside from affecting immune system function, cognitive abilities, and metabolism, consequences of sleep deprivation affect economies annually through billions of dollars in lost productivity.

Diagnosing sleep disorders is a comprehensive process and substantial time commitment, requiring patient-monitoring for 12–36 hours in a sleep center. As the setting is unfamilar and patients must ...

Accu-Injection – Assisting in Daily Medical Injection Regimen

On a daily basis, millions of people self administer subcutaneous injections of medication. While this daily routine becomes automatic to the patient, injection site management is an important choice. Over time, repeated injection points may become sore or develop irreparable damage. An attempt to avoid same injection sites is made but requires accounting for previous and forecasting upcoming injection points.

Complications of repeated subcutaneous injections may range from patient discomfort, bleeding and sustained sensitivity to tissue damage. In extreme cases, repeated same-site injection results in the destruction of fatty tissue leading to disfigurement, called lipoatrophy. Routine injections are typically performed by relying upon memory or a log book to determine previous ...

Every year, about 250,000 cases of torn knee anterior cruciate ligaments (ACL) happen in the US alone, and they all need reconstructive surgery and a long recovery time. In the NFL, they account for one in six injuries. We only hear of such injuries about famous athletes like David Beckham or Tiger Woods, but female athletes have an even higher risk of ACL tears than men and kids. To my knowledge, this never made the news. It is a leading injury concern according to CDC statistics and often times is a career-ender. The proponent did a Quality Function Deployment (QFD) study, which unveiled important inherent opportunities to develop an active knee brace: the force that can cause ACL rupture ...

In the Major Auto Hemo Therapy (MAHT) an amount of blood is drawn from the patient and put in contact with a therapeutic dose of ozone (O3). Ozone is a gas with a high blood solubility and dissolves quickly into blood, generating a cascade of events which may be beneficial in a number of pathologies, where improved tissue oxygenation should be achieved. MAHT is a completely manual procedure where blood, drawn (by gravity, or by applying vacuum) from a patient vein is collected into a glass bottle (glass is inert to ozone) containing a certain amount of anticoagulant. A certain O3 dose is then added to the bottle and kept in direct contact with blood for a few minutes ...

Abstract:
Radiofrequency ablation (RFA) is a medical procedure used for treatment of cardiac disorders such as arrhythmia or destruction of cancerous tumors in lung, kidney, breast, liver or any other dysfunctional tissue diseases. RFA is also used for treatment of varicose veins, severe chronic pain as well as many other medical uses.

RFA Side Effects and Complications:
Although radiofrequency ablation is a relatively safe procedure, serious complication and side effects can occur including tissue charring and blood coagulation, blood clot and stroke, cardiac perforation, pulmonary vein stenosis, etc.

Solution:
The conceptual design of the “Advanced Multi-Electrodes RFA Catheter” is based on a multi-point electrode design which monitors temperature and tissue contact quality. Electrode’s temperature is measured at both end points, ...
