Flexible active electrodes for large scale neural recording
Technology Description This technology is a neural recording architecture that dramatically increases the available recording density without increasing the number of wires needed. From the same number of wires, the architecture improves density by nearly two orders of magnitude, achieving sub-millisecond temporal resolution and spatial resolution...

Cab Entry and Exit Fall Prevention System
Technology Description This device is a mechanical handle retrofitted to the cab. This handle swings out from the driver’s foot-well and impedes entering and exiting the cab in an improper manner by essentially requiring interaction and 3-point contact. It provides an accessible, rigid point of contact. The overall shape of the handle can be...

Multi-Actuator System for Active Sound and Vibration Cancellation
Technology Overview A multi-actuator system for sound and vibration cancellation utilizes a LMS type algorithm having an adaptive filter. However, the error signal rather than the input is filtered through an adjoin filter of the error channel to drive an adaptive filter which in turn drives, for example, a loudspeaker to provide destructive interference...

Method of Producing Oleofurans
Technology Description This technology is a method for making oleofurans which can be derived from biomass and used as precursors for high performance oleofuran-based surfactants. This method minimizes or eliminates the use of toxic and/or expensive reagents, such as trifluoroacetic acid, and produces a small number of bi-products. This process produces...

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...

Fluorescence microscope for high resolution imaging and single-molecule tracking
SummaryDespite improvements in the field of fluorescence microscopy, a major drawback of existing microscopes is their spectral resolution, as they can distinguish only up to 3-4 colors at a time and requiring multiple excitation sources, limiting their practical use in biomedical research. Scientists at OHSU have recently solved this problem by developing...
