    A situational display and a means for creating the display are disclosed. The display comprises a moving line or raster, on a cathode ray tube, which is disposed intermediate of two columns of lamps or intensifications on the cathode ray tube. The raster and lights are controlled in such a manner that pairs of lights define a line which is either tracked or chased by the raster in accordance with the relationship between the optimum and actual values of a monitored parameter

    A Tele-Operated Display With a Predictive Display Algorithm

    Tele-operated display systems with head mounted displays (HMD) are becoming popular as visual feedback systems for tele-operation systems. However, the users are suffered from time-varying bidirectional delays caused by the latency and limited bandwidth of wireless communication networks. Here, we develop a tele-operated display system and a predictive display algorithm allowing comfortable use of HMDs by operators of tele-operation systems. Inspired by the kinematic model of the human head-neck complex, we built a robot neck-camera system to capture the field of view in any desired orientation. To reduce the negative effects of the time-varying bidirectional communication delay and operation delay of the robot neck, we developed a predictive display algorithm based on a kinematic model of the human/robot neck-camera system, and a geometrical model of a camera. Experimental results showed that the system provide predicted images with high frame rate to the user

    Charged particle display

    An optical shutter based on charged particles is presented. The output light intensity of the proposed device has an intrinsic dependence on the interparticle spacing between charged particles, which can be controlled by varying voltages applied to the control electrodes. The interparticle spacing between charged particles can be varied continuously and this opens up the possibility of particle based displays with continuous grayscale.Comment: typographic errors corrected in Eqs (37) and (39); published in Journal of Applied Physics; doi:10.1063/1.317648

    Musselman Display Case

    The Gettysburg College campus without the influence of the Musselman family would be a very different place. The Musselman name is not one that can be easily overlooked on campus, as numerous buildings are named after the famous apple processing family located in Biglerville, Pa. Yet without the generosity of the Musselman and the Emma G. Musselman foundation, the college would not only be lacking Musselman Stadium, Musselman Hall, and Musselman Library, but also the Bream Wright Hauser Field House, and thousands of dollars in scholarships awarded to students over the past several years. The Musselmans have undoubtedly left a strong imprint on the college and the greater community, and their charity has touched a countless number of people. Within the Musselman Library there is a display case devoted to the family, without whom the library itself would cease to exist. Inside this display, there are several photographs exploring the history and legacy of this remarkable family, and paying tribute to those who have brought so much to Gettysburg College.

    Display elements and gaps: a comparison of flat panel display characteristics

    Get PDF
    The relation between typical flat panel display characteristics and display quality was studied. Subjective preferences were obtained with respect to simulated black-on-white flat panel displays. The displays differed in the sort of separation between the display elements and the shape of these elements. Further, the height/width ratio of the front was studied in relation with a fixed font matrix. The preferences were obtained through a paired comparison of all possible pairs of simulated displays.\ud \ud The observers appeared to be sensitive and to respond to differences in the stimuli. It is not clear, however, if they responded to the type of gap and shape of display elements or to the luminance modulation, which co-varied with the two experimental factors. It can be concluded however that the integrity of the character area is important to the observers. Further, the usefulness of interactively designing spatial display characteristics and the font is discussed
