Biomedical Engineering

ASAP: Automated Sigma Analysis Platform
Our team has been working with Baxter to improve optical and software techniques to quantify flow rate of their Sigma Spectrum drug infusion pump. Current methods for flow rate calibration of hospital infusion pumps are subjective and prone to errors such as evaporation. Developing an accurate and thorough calibration set-up can be tedious, costly, and space-inefficient. We have developed a novel, inexpensive calibration device to validate infusion pump flow rate intended for use in research and development, and quality assurance of Baxter’s pumps.

Pediclear
During spinal fusion procedures, surgeons need a better way to detect defects in the pedicle tract in order to determine whether it is safe to implant pedicle screws. We designed a surgical probe, Pediclear, that senses changes in vibration pattern as it moves against the walls of the pedicle tract and alerts the surgeon to the presence of a breach. The solution adds certainty to breach detection, reduces false positive rates, and aids in resident training without adding extra time, equipment, and cost to the procedure.

Proteus Medical
Canines are the most common offenders of consuming foreign bodies, requiring a veterinary visit to remove the object to prevent further harm. Endoscopic retrieval is the preferred method of extracting these foreign bodies. However, endoscopic retrieval devices on the market today are neither robust nor reusable, often deforming after single use. At Proteus Medical, our team has developed a unique design that will reduce both the retrieval time and yearly expenditures. Together, we aim to revolutionize the endoscopic retrieval field through our novel device.

Camera Tip-Tilt Mount
This project aimed to create a vibration reducing camera mount that was attachable to a remote controlled robot. Images from the camera became blurry as the robot traveled over rough terrain, hindering its ability to navigate. This was solved by creating a boom system that levels the camera's field of view as the robot pitches up and down.

Cryogenic Seal and Release Mechanism
The University of Rochester Laboratory for Laser Energetics (URLLE) tasked the team to design and develop a controllable, one-time use sealing mechanism that can be integrated into their new cryostat shroud-retraction designs. The sealing mechanism is needed to seal Helium-3 gas under both vacuum and cryogenic conditions while creating minimal impulse upon actuation for seal breakage. Breakage of the seal needs to be completed before retraction of the shroud in order to expose the fuel target to the lasers that will initiate combustion.

Birefringent Stress Plate
We have built an interactive exhibit for the Rochester Museum & Science Center that demonstrates how optical materials behave differently under stress, in particular how some materials exhibit birefringence when stressed. To do this we constructed a wooden frame capable of holding a light source; polarizers; and several layers of glass, some for the birefringent effect, some for safety and some for protecting the exhibit. When a person steps on the plate, polarized light gets modulated based on the stress in the glass and creates patterns of light easily visible to viewers.

Effects of Ultraviolet Radiation on Manuscripts
Multi-spectral imaging is used to recover illegible text from damaged manuscripts. The technique employs light emitting diodes at a wide range of wavelengths including visible, infrared, and ultraviolet. The International Commission on Illumination (CIE) recommends that manuscripts are not exposed to any level of ultraviolet radiation, despite the wavelengths' role in text recovery. My project attempts to determine the levels of total ultraviolet exposure that will induce irreversible damage to the manuscripts.

Historical Manuscript Imaging
Our team has designed an imaging system which can be used to extract clear, readable images of entire pages from very fragile, ancient manuscripts. These manuscripts cannot be opened past 30 degrees due to the delicate nature of the glue in the binding. Our design utilizes a plexiglass prism filled with liquid silicone and an internal mirror which gets inserted into the binding of the partially open manuscript. Reflections within the prism allow for an entire page to become clearly viewable without having to open the manuscript past the 30 degree limit.

Neural Adaptation to Spatial Phase Modulations in High Order Ocular Aberrations
Optical aberrations in the human visual system degrade the amplitude (MTF) and phase relationships (PTF) among spatial frequencies (SFs) in the retinal image. Furthermore, it has been found that long term exposure to optical aberrations progressively alters the visual perception through neural adaptation mechanisms. This study uses compound Gabor grating stimuli displayed with an adaptive optics system to test the hypothesis that neural compensation for phase shifts in broadband stimuli is one of the mechanisms underlying this adaptive process

Optimizing Brewster Angle Rayleigh Scattering Detection of Surface Nanoroughness
Flat optics are very smooth flats that usually have a surface roughness less than 10 Å. To test the roughness of these flats, a scatterometer has been developed to analyse scattered light from a laser incident on the flat. This project is optimizing the instrument by adding a spacial filter and specifying a new laser, using Rayleigh scattering. Brewster angle is utilized to minimize reflections. This project will also set a detector at specific angle at which the scattered light power at that angle can be used to distinguish laser grade flats from standard grade flats

Quantum-Enabled Super-Resolution Microscopy
The most widespread physical limitation to optical imaging resolution lies in how a lens is able to focus light, called the "Rayleigh limit" or "diffraction limit." Most often resolution is a fixed parameter of the imaging system. Literature reports monochromatic imaging with coherent and incoherent light to reach at least 0.01 of the Rayleigh limit, limited by quantum noise. An interferometer is constructed to probe spatial modes of a slit object using a spatial light modulator and ultimately surpass resolution of 0.01 Rayleigh limit features

Up.Periscope
We are designing three options for an analogue periscope to allow passerby's to view the distant sound in New Rochelle over downtown buildings. First, two reflective mirrors with diameters of ~3 feet, positioned ~70 feet apart, and oriented 45 degrees respective to each other, will allow an image to be collected by the top mirror to project onto a second mirror at ground level. A variation of this setup is to replace the bottom mirror with a telescope. Lastly, we have designed a lens relay system consisting of 7 catalogue relay lenses, an objective, and an eyepiece.
