Display system

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.

Pervasive computation is human centered: it permeates our physical world, helping us achieve goals and fulfill our needs with minimum effort by exploiting natural interaction styles. Remote interaction with screen displays requires a sensor-based, multimodal, touchless approach. For example, by processing user hand gestures, this paradigm removes constraints requiring physical contact and permits natural interaction with tangible digital information. Such touchless interaction can be multimodal, exploiting the visual, auditory, and olfactory senses.Ministerio de Educación y Ciencia and Amper Sistemas, SA

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

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

The application of workflows to digital heritage systems

Digital heritage systems usually handle a rich and varied mix of digital objects, accompanied by complex and intersecting workflows and processes. However, they usually lack effective workflow management within their components as evident in the lack of integrated solutions that include workflow components. There are a number of reasons for this limitation in workflow management utilization including some technical challenges, the unique nature of each digital resource and the challenges imposed by the environments and infrastructure in which such systems operate. This thesis investigates the concept of utilizing Workflow Management Systems (WfMS) within Digital Library Systems, and more specifically in online Digital Heritage Resources. The research work conducted involved the design and development of a novel experimental WfMS to test the viability of effective workflow management on the complex processes that exist in digital library and heritage resources. This rarely studied area of interest is covered by analyzing evolving workflow management technologies and paradigms. The different operational and technological aspects of these systems are evaluated while focusing on the areas that traditional systems often fail to address. A digital heritage resource was created to test a novel concept called DISPLAYS (Digital Library Services for Playing with Antiquity and Shared Heritage), which provides digital heritage content: creation, archival, exposition, presentation and interaction services for digital heritage collections. Based on DISPLAYS, a specific digital heritage resource was created to validate its concept and, more importantly, to act as a test bed to validate workflow management for digital heritage resources. This DISPLAYS type system implementation was called the Reanimating Cultural Heritage resource, for which three core components are the archival, retrieval and presentation components. To validate workflow management and its concepts, another limited version of these reanimating cultural heritage components was implemented within a workflow management host to test if the workflow technology is a viable choice for managing control and dataflow within a digital heritage system: this was successfully proved
