Supporting design, prototyping, and evaluation of public display systems

Abstract: Public displays have become ubiquitous in urban areas. They can efficiently deliver information to many people and increasingly also provide means for interaction. Designing, developing, and testing such systems can be challenging, particularly if a system consists of many displays in multiple locations. Deployment is costly and contextual factors such as placement within and interaction with the environment can have a major impact on the success of such systems. In this paper we propose a new prototyping and evaluation method for public display systems (PDS) that integrates augmented panoramic imagery and a light-weight, graph-based model to simulate PDS. Our approach facilitates low-effort, rapid design of interactive PDS and their evaluation. We describe a prototypical implementation and present an initial assessment based on a comparison with existing methods, our own experiences, and an example case study.

Luminescence Quenching of Ligand‐Substituted Molybdenum and Tungsten Halide Clusters by Oxygen and Their Oxidation Electrochemistry

Abstract: Cluster compounds (TBA)2[Mo6I8(CF3SO3)6], (TBA)2[W6I8(CF3SO3)6], and (TBA)2[W6Br8(CF3SO3)6] are prepared and structurally characterized from single-crystal X-ray diffraction data. All compounds show red emission on photoexcitation at 400 nm. However, the phosphorescence of crystalline samples is quenched in the presence of oxygen, depending on the partial pressure of oxygen. The distinct phosphorescence-quenching behavior of compounds containing trifluoromethanesulfonato (CF3SO3–) ligands is compared with corresponding compounds with trifluoroacetato (CF3COO–) and p-toluolsulfonato (CH3C6H4SO3–) ligands. By studying these compounds, we investigate the relationship of more- or less-electron-withdrawing ligands (L) of (TBA)2[M6X8L6] halide (X) clusters, their redox potentials (E0), and their phosphorescence-quenching behavior under variable oxygen partial pressures.

Tool i.e. medical gripping tool, for e.g. examining, body part of patient, has two branches provided, where one branch is deformable during movement and is formed of deformable framework and exhibiting flexible flanges

Abstract: The tool has two branches provided, where one branch (1) is deformable during a movement and is formed of a deformable framework. The deformable branch exhibits flexible flanges (2), where a connecting unit (4) e.g. rods, extends between the flexible flanges. The flanges exhibit v-shaped recesses, where the connecting unit lies in the v-shaped recesses, and the thickness of the connecting unit corresponds to a breadth of the recesses. The shape of ends of the connecting unit and the recesses corresponds to one another.
