Visual Field Simulation Using OCT and OCT Angiography
Summary Preventing glaucoma disease progression requires regular monitoring and timely treatment. However, current assessment of visual field loss is subjective and can be unreliable for monitoring small progressive vision loss. Accordingly, Dr. David Huang et al. developed an OCTA test that produces simulated visual fields. The test provides a more...

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...
