Sleep Apnea Detection System
Technology Overview OHSU has developed a non-obtrusive system to monitor and diagnose sleep apnea and hypopnea through the use of load cells installed in the supports of a patient’s bed. The load cells continuously and independently measure the weight supported by each leg of the bed, and are sensitive enough to pick up small fluctuations in weight...

Differentiating extravascular from intravascular MRI contrast using T2* and SWI weighted sequences
Non-invasive imaging detection of tumor-associated macrophages in glioblastomaSummaryTracking immune responses in chemotherapy treated glioblastomas is important for interpreting disease progression, but current methods are invasive and require biopsies. OHSU researchers have developed an MRI-based method to detect tumor-associated macrophages to enable...

A fast and robust standard-deviation based method for bulk-motion compensation in phase-based functional OCT
Standard deviation phase compensation for OCTA and Doppler OCTThis invention involves a novel bulk motion compensation method for phase-based functional OCT. The two widely used phase compensation methods are the “average” (AVG) method and the “histogram” (HIST) method, wherein the latter estimates the vessel shadow artifact...

Body heat-powered heart beat detection circuit
Technology Description The inventors have designed, implemented, and demonstrated an integrated circuit architecture for robust and automated detection of heartbeats from a two-electrode ECG signal. This uses sufficiently low power (~20μW) that it can be powered entirely by human body heat from a cm-scale TEG module at ~20mV, including wireless...

Thermal Fan
Technology Description This thermal fan device operates, in principle, similarly to a heat pipe by utilizing the latent heats of vaporization and condensation with the corresponding phase changes to move a fluid like air. A phase change working fluid is contained within a confined volume that is exposed to the low-grade heat. The working fluid is selected...
