Real-time protocols originated from standard Ethernet technology have been gradually developed over the last decade. Candidates of real-time Ethernet protocols are EtherCAT and PROFINET IRT from Beckhoff and Siemens, respectively. In contrast to standard Ethernet, data-link layers of both Ethernet-like networks are modified from IEEE 802.3 in order to improve real-time capabilities for critical communications...
Communication networks are essentially the backbone of industrial automation systems such as Baggage Handling Systems (BHS) and are experiencing technological transition from traditional fieldbus to Real-time Ethernet (RTE). EtherCAT is evolving into one of the fastest RTE protocols due to its unique “processing on-the-fly” characteristic. This paper presents how EtherCAT can be the key technology...
This paper proposes an energy sharing adjustable speed drive system for dual-escalator applications. The primary goal is to harvest the regenerative energy produced by downward running escalator and share the energy with the upward running escalator. Thus the system energy consumption is reduced. The energy sharing is realized by inter-connecting the DC buses of two adjustable speed drives. An isolated...
In this paper, a new method is utilized to develop the hermetic thermoplastics through modification of conventional LCP resins. Thermoplastic materials are synthesized for producing a hermetic barrier with a cavity structure made based on the materials compositions: near-hermetic liquid crystalline polymers (LCP), nano-sized mineral fillers, adhesion promoters, compatibilizers, inorganic microparticles...
