Design of multi-element antennas (MA) for small mobile terminals operating at higher frequencies remains challenging despite smaller antenna dimension and possibility of achieving electrically large separation between them. In this paper, the importance of the type of radiating elements operating at 3400–3600 MHz and their locations on the terminal chassis is highlighted. An isotropic radiation...

This paper introduces an originally designed tracked robot. This robot belongs to the VGSTV (Variable Geometry Single Tracked Vehicle) category. It is equipped with two tracks mounted on an actuated chassis. The first joint is used to articulate the chassis and the second one to keep the tracks tightened. By controlling the chassis joint it becomes possible to adapt the shape of the tracks to t...

Due to the high rolling rate of a regular crawler paddy harvester and absence mature first season products ratooning rice, combined with planting mode harvest requirements triangular rice is specifically designed. The structure steering principle chassis are described. hydraulic system simulated analyzed by AMESim2020 (Guangzhou, China) verify rationality its design; RecurDynV9R4 used simulate ...

This document specifies an Inter-Chassis Communication Protocol (ICCP) that enables Provider Edge (PE) device redundancy for Virtual Private Wire Service (VPWS) and Virtual Private LAN Service (VPLS) applications. The protocol runs within a set of two or more PEs, forming a Redundancy Group, for the purpose of synchronizing data among the systems. It accommodates multi-chassis attachment circui...

Actively reconfigurable chassis enable planetary mobile robots to access more varieties of terrain. While typical approaches for exploiting such mechanisms reply on feedback control, it is beneficial to consider actively controlled elements at planning time rather than during motion execution. In this paper we present an approach for extending work in model-predictive trajectory generation to a...

BACKGROUND Synthetic organism-based biotechnologies are increasingly being proposed for environmental applications, such as in situ sensing. Typically, the novel function of these organisms is delivered by compiling genetic fragments in the genome of a chassis organism. To behave predictably, these chassis are designed with reduced genomes that minimize biological complexity. However, in these ...

Due to the increasing number of body styles, engine/gear combinations and the variety of modern control systems, the use of simulation techniques becomes more and more important in the development process of classical chassis as well as chassis control systems. Following GM’s Road-Lab-Math (R-L-M) strategy, the number of prototype cars in ongoing and future vehicle programs will be significantl...

Present-day computer-based information systems are increasingly required to be open systems. This means that they must cope with open networks, heterogeneous interoperable hardware and software systems, and, above all, evolving and changing requirements. The CHASSIS project aims to develop a software and methodology framework for (i) the securityand reliability-oriented systematic design and co...
