Electronic Toric Marker is a medical instrument used in the case of Glaucoma eye disease, which is primarily observed in millions of sugar patients. Toric Marker head places two small lines/dots across pupil for pre-op/intra-op reference marking for alignment purpose. The two lines should be aligned horizontally (0 and 180 degree plane) very accurately with an alignment error of the order of one degree. 1-Dimensional Toric Marker, which balances the marker dots in two directions left and right, is available in the market. I have designed 2-Dimensional Toric Marker, which balances the marker dots in four directions left, right, front, and back. Electronic Toric Marker reduces alignment error compared to non-electronic Toric Marker.

Each marker head is nearly sharp ...

In last few decades, many attempts have been made on person identification using biometric and non-biometric features. The main objective of person identification is to ensure that the services are accessed only by a legitimate user. But some biological parameters that are used as uni-model biometric fail to provide the guarantee of the presence and aliveness of the person as, voice can be copied through microphone, finger print can be collected on silicon surface, and iris can be copied on contact lenses.

Unimodal biometric systems have to contend with the variety of problems such as noisy data, intra-class variations restricted degrees of freedom, non-universality, spoof attacks and unacceptable error rates. Hence in this project a new approach on ...

In vitro studies of cell behavior are an essential prerequisite in determining in vivo responses to pharmacological agents, cell therapies, biomaterials, and implantable devices. However, culturing mammalian cells on a conventional Petri dish is not an accurate representation of the in vivo environment and as a result cells behave in a way that may not be medically relevant. To address this issue, a design for an inexpensive culture surface or scaffold has been designed and manufactured at Worcester Polytechnic Institute. Cells cultured on this scaffold exhibit significant changes in morphology, cytoskeleton arrangement, gene expression, and ECM formation when compared to cells grown on conventional substrates. The scaffold can be made from a variety of synthetic or natural materials since ...

Donald W. Collins, Ph.D., has been involved in developing the ACADZ 3D STL Radiation Compensator Negative Plastic Mold Filter Conversion Software/Hardware - “Combined Package” to convert the DICOM RT Optimal Fluence Patient Treatment Plan Files (.dcm) into 3D (.stl) code files to be used on a 3D Printer for printing 3D Compensator Negative Plastic Molds. This ACADZ “Combined Package” will be used by the Radiation Hospital or Clinic, In-House, for translating the Cancer Patient’s DICOM RT Optimal Fluence Treatment Plan Files (.dcm) or 3D Compensator Negative Plastic Mold Filter Files (.asc) for each Patient’s Treatment Plan Field into XYZ 3D Printer (.stl files) to be used on the 3D Systems Corporation’s – 3D Systems ZPrinter® 450 for printing the ...

In an attempt to understand the cause, and find a solution for Parkinson disease, I thought about some similarities on a problem that I was having with an old computer. I had upgraded some programs, but had not renewed the hardware, and when I went to open a new high definition picture, the computer would try to open the file, but would struggle and vibrate, and then lock up. The only way to overcome this problem was to turn off the computer, by turning off the power switch. On researching the computer problem, one of the suggestions was to lower the resolution setting on the computer.’ Mr Ettridge added. This solution worked, and the computer worked normally. I realized ...

Presents an Artificial Intelligence auto learning, early auto diagnostic, auto alert vital signs wireless Plaster. It can be used for real-time monitoring of ECG, respiratory rate, falling and patients temperatures. The proposed device is a lightweight plaster, attached to the chest. It has several sensors, ECG, 3D accelerometer for chest respiratory rate. Body position and patient’s activity, skin temperature, hand proximity sensor, altitude, oxygen level in the blood and proximity to smart phone or any fix location wireless recipient.

It can wirelessly transmits, while on “event”, the patient’s ECG signal with all data stored from other sensors, to mobile phone or to wireless mesh to internet device around it. The device runs several processes in parallel that ...

Ischemia, a local blood supply disorder resulting from reduction or complete deficiency of blood supply in an organ or in a tissue caused by constriction or obstruction of its blood vessels, resulting in hypoxia, malnutrition and finally necrosis of the part of an organ suffering from ischemic process, is a frequent phenomenon in pathogenesis of many clinical conditions, as well as during performing surgical procedures. The causes of this phenomenon include, among others, formation of fibrin clots of abnormal stability and structure. Epidemiologic data obtained from ex vivo and in vitro studies indicate that the abnormal properties of fibrin clot are related to the occurrence of ischemic strokes, myocardial infarction or thromboembolic vascular disease. In general, the clots composed ...

V-10 is a peptide-based material that has been developed through10+ years of research. It consists of a novel sequence of 31 amino acids with several domains serving unique purposes and is known as a multi-domain peptide. This peptide is easily produced by solid phase synthesis, in the lab. The peptide is designed to self assemble to form a nanofibrous matrix that mimics natural extracellular matrix. Our synthetic matrix can be sheared, only to reform, due to the nature of the hydrophobic interactions and hydrogen bonds between peptides. These matrices form a hydrogel in the body, have been engineered to produce new blood vessels when injected.

We want to reduce the risk of Sudden Infant Death Syndrome (SIDS) with our novel product. Our device is a pulse-oximetry based rescue garment worn by an infant on the hand. The device monitors heart rate and blood oxygenation. Detecting and interrupting dangerous sleep episodes is theoretically the best mechanism of rescue for infants at risk due to SIDS. If the wearer experiences a dangerously low heart rate and/or blood oxygen saturation episode, he/she will experience a safe electrical stimulation that will effectively rouse them. The rescue stimulus is minimal so as not to cause undue distress.

It is important to note, however, that the Anti-SIDS device provides a live saving intervention. It communicates wirelessly with the caregiver's tablet ...

Two sterile medical devices keep organs warm, moist, protected and bands (not straps, bands prevent cutting into organs) cover and surround large open wound cavities, including evisceration's (EV), by pulling quick release self adhering wound dressing tabs with adjustable locking plates to assure proper fit.

Point of injury patients often bleed out/die within "golden" hour; survivors may suffer permanent damage to vital organs if not kept warm, moist, protected between injury, transport & care at medical facility. Battlefield extraction, Special Operations, averages 4 to 5 hours, up to 72 hours. EV-SkinProTX(TM) the only non-invasive device, keeps organs warm, moist, protected. Utilizes saline bags all medics, ambulances, & medical facilities use. EV-SkinProTX, lightweight ions, podiatric surgery, OBGYN cesarean, abdominal, ...
