This paper purposes a portable multispectra tunable forensic lens for jadeite analysis. The visible and ultraviolet light are used to detect the absorption spectra of natural jadeite, implement jadeite, and jadeite color spectra around 550∼700 nm. Besides, tunable lens with three-step (5, 7 and 10 X) magnification is based on the dielectric liquid lens.
In this paper we present a method to stimulate multiple muscles in a human arm to perform interaction tasks, using an implanted Functional Electrical Stimulation (FES) neuroprosthesis. The unstable effect arising from interaction tasks is considered, and the arm stability is directly treated as one of the control objectives in the controller design. By exploiting the kinematic and muscular redundancy...
This paper describe an easy-to-handle approach to probe cellular behaviors via applying a force on microstructures (mechanical stimulation) with mammalian cells. The external mechanical stimulation on cells was performed through applying various forces on the polydimethylsiloxane (PDMS) microstructures after cells adhered onto it. After mechanical stimulation on PDMS microstructures for 2 hours using...
We present a method for controlling a neuroprosthesis for a paralyzed human arm using functional electrical stimulation (FES) and characterize the errors of the controller. The subject has surgically implanted electrodes for stimulating muscles in her shoulder and arm. Using input/output data, a model mapping muscle stimulations to isometric endpoint forces measured at the subject's hand was identified...
We present a method for controlling a neuroprosthesis for a paralyzed human arm using functional electrical stimulation (FES). The subject has surgically implanted electrodes for stimulating muscles in her shoulder and arm. Using input/output data, a model is identified that describes the mapping from muscle stimulations to the endpoint force measured at the subject's hand. To compute the muscle stimulations...
