Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society Volume 13: 1991.
The elements used to model the physiological response of tactile systems to vibratory inputs are described. Included are the effects of the vibrator, skin/tissue interface and two tactile receptor classifications, Pacinian (PC) and non-Pacinian (NP)

Proceedings of the Fifteenth Annual Northeast Bioengineering Conference.
The authors describe work toward the implementation of a tactile vision information system (TVIS). The prototype system consists of a video camera for image acquisition, a microcomputer for image processing, and a 16*16 vibro-tactile array for image

Proceedings of the 1988 Fourteenth Annual Northeast Bioengineering Conference.
The overall transfer function for a tactile vision information system (TVIS) used as an aid to the visually impaired is described. Included in this transfer function are the electromechanical vibrators, the skin interface, and the tactile skin sensor

A technique by which the retina can be isolated from the turtle eye is described. Scanning electron microscopy revealed morphological variability between preparations and also between regions of the same one. Large areas were often totally free of an

A new method measures the spectral absorption of small volume samples having peak optical densities ( D p ) too high (up to 50 and higher) to be measured by standard direct or indirect methods. This method specifically corrects for the effect on the
