In this paper, the control problem in retinal imaging adaptive optics systems is generalized to that of shape control for a flexible membrane representing a deformable membrane mirror. Due to the dynamic nature of the aberrations in the eye, the shape control problem addressed is the tracking of an unknown and time-varying shape for a distributed membrane (i.e. desired shape of the mirror). The proposed...
The social interaction, guidance and support that a socially assistive robot can provide a person can be very beneficial to patient-centered care. However, there are a number of conundrums that must be addressed in designing such a robot. This work addresses two main limitations in the development of intelligent task-driven socially assistive robots: (i) recognition and identification of human gesticulation...
The imaging of the retina tissue in the back of the eye is important for a number of applications, such the early detection of eye disease. Adaptive optics systems are being increasingly used to provide clear images of the retina tissue by compensating for the eye's optical imperfections, also referred to as aberrations. Although current retinal imaging adaptive optics systems can compensate for some...
This paper presents a review of as well as solutions to control system design issues for adaptive optics systems used in retinal imaging. The development of retinal imaging systems allows for early diagnosis of eye diseases. Such systems can increase the quality of life of patients as well as curtail increasing health care costs through early eye disease detection and treatment. A discussion on control...
This paper presents a novel and generic PC/PLC-based software/hardware architecture for the control of flexible manufacturing workcells. The proposed implementation methodology is based on the utilization of any one of the available formal discrete-event-system control theories in conjunction with state-of-the-art industrial programmable-logic controllers (PLCs). The methodology has been illustrated...
