2010-296 – Communications between electronic components employ one of a number of signaling schemes. Generally, digital communications use one of two classes of signaling schemes: single-ended or differential signaling. A single-ended signaling channel employs transmission of n-level (typically 2-level) signals through a single signal conductor, using a ground or power conductor as the reference for... Read More
2010-294 – In laparoscopic radical prostatectomy (RP), the pedicle is transected, but care must be taken to preserve the adjacent neurovascular bundle. Electrocautery or other hemostatic energy sources are not used due to concerns over collateral thermal damage, adhesives or sutures alone have not been shown to provide reliable hemostatis, and existing clips can be difficult to place and adjust. A... Read More
Transpulmonary Induction of Therapeutic Hypothermia (In Collaboration with Minnesota High-Tech Resources LLC)
2010-284 – Therapeutic hypothermia is a widely accepted methodology for mitigating injury to vital organs following ischemic insults.

This device sits at the abdominal opening and remains stable by means of adhesive tape at the lower rim. There are no robotic mounts or arms holding... Read More
2010-233 – The inner ear vestibular system reflexively controls eye position in the orbits. For example, when the head is tilted to the side (ear moved toward the shoulder) the eyes roll in the opposite direction so that they stay oriented to the horizon. This eye movement is called head tilt induced ocular counter roll and is mediated in part by the otolith organs of the vascular system. Damage to... Read More

Use of Pittsburgh Compound B (PiB) Molecules and PiB-Positron Emission Tomography/Computed Tomography (PiB-PET/CT) Imaging for the Identification and Diagnosis of Meningiomas
2010-007 – Meningiomas are a common tumor often found in the thin layers of tissue that surround the brain. However, many other types of tumors can arise in the same locations. Variation in the appearance of meningiomas can make the accurate diagnosis of meningioma difficult based on current methods, such as Computed Tomography (CT) and Magnetic Resonance Imaging (MRI). Pathologists can accurately... Read More

2009-264 – Conventionally, nuclear medicine gamma cameras employ an energy window centered in the primary gamma ray energy emitted by the radioisotope being detected. For example, with Tc-99m, a 20% energy window (from 126-154 keV) is centered on the 140 keV gamma rays. At lower energies, scatter within the patient and the gamma camera degrade image quality and these events are not considered useful. ... Read More
