Abstract: A semiautomatic (1) sensorized apparatus for the execution of inspections of the railway pantograph (P) is detachably associated to a railway pantograph and allows the execution of two distinct tests in succession: i) the first one, which monitors the functional properties of the pantograph, based on the characterization of the thrust force generated by the main suspension; ii) the second, which aims to identify global and local defects, adopting the principle of inspection by means of vibration analysis.

Abstract: Provided is a wearable assisted-walking device including one lower attachment body to the foot defining a lower anchoring point at the heel of the foot of a leg of the user; an upper attachment body to an upper part of the leg proximal from the knee defining an upper ventral anchoring point and an upper dorsal anchoring point arranged on the opposite side of the coronal plane of the user; and an intermediate attachment body defining a first intermediate anchoring point, a second intermediate anchoring point and a third intermediate anchoring point, each anchoring point movable respect and connected by cables to the leg; the intermediate attachment body being adapted to store the energy by a relative motion between the anchoring points and then use it for assist walking.

Abstract: Optical solutions to address and overcome the issues of superseding/replacing electrical interconnection networks have generally exploited some form of optical space switching. Such optical space switching architectures required multiple switching elements, leading to increased power consumption and footprint issues. Accordingly, it would be beneficial for new optical, e.g. fiber optic or integrated optical, interconnection architectures to address the traditional hierarchal time-division multiplexed (TDM) space based routing and interconnection to provide reduced latency, increased flexibility, lower cost, and lower power consumption. Accordingly, it would be beneficial to exploit networks operating in multiple domains by overlaying mode division multiplexing to provide increased throughput in bus, point-to-point networks, and multi-cast networks, for example, discretely or in combination with wavelength division multiplexing.

Abstract: Scalability and energy efficiency are key issues in data centers imposing tight constraints on the networking infrastructure connecting the servers. Optical interconnection mitigates electronic limitations but the additional flexibility offered by WDM and datarate across a data center interconnection network requires architectural design, photonic technologies, and operating strategies be selected and optimized to meet power consumption requirements. Multi-plane architectures based upon space-wavelength domain architectures have been proposed to overcome scalability limitations. It would be beneficial to extend space and time switching domains with the wavelength domain for additional capacity to increase throughput as well as providing same electro-optic interface.
