Mobile Context

In the context of healthcare monitoring, it is necessary to transmit vital information from the patient to an interface managed by the hospital staff. In this paper, the authors consider a system in which a patient can move within a hospital room and the data collected by sensors are transmitted to a distant receiver placed on the ceiling. The authors investigate the potentiality of using infrared communications for the transmission of information in this mobile context, by considering the simplest modulation scheme based on On-Off Keying (OOK) technique. In order to represent patient mobility in the room, the authors use a model for the patient location based on a Gaussian distribution over the three axes of mobility in the room. In addition, they consider different scenarios, considering either a Line Of Sight (LOS) configuration or a diffuse one. From the obtained results, the authors can determine by evaluating the transmission probability of outage, the potentiality of this technology to ensure the communication between sensors and the collecting point.

Loop Track

A novel closed loop track based multi-head robot has been developed to increase material handing throughput. This robot allows for waves of autonomous robot heads to move materials in the working path by eliminating the traditional return path. Distributed control architecture was developed using a system comprising of desktop, embedded and single board PC’s, some linked by infrared communications. This paper discusses the design and impact of such a control architecture, and looks at some performance boundaries.

AbstractAmong light-based free-space communication platforms, mid-infrared (MIR) light pertains to important applications in biomedical engineering, environmental monitoring, and remote sensing systems. Integrating MIR generation and reception in a network using two identical devices is vital for the miniaturization and simplification of MIR communications. However, conventional MIR emitters and receivers are not bidirectional due to intrinsic limitations of low performance and often require cryogenic cooling. Here, we demonstrate that macroscopic graphene fibres (GFs) assembled from weakly-coupled graphene layers allow room-temperature MIR detection and emission with megahertz modulation frequencies due to the persistence of photo-thermoelectric effect in millimeter-length and the ability to rapidly modulate gray-body radiation. Based on the dual-functionality of GFs, we set up a system that conducts bidirectional data transmission by switching modes between two identical GFs. The room-temperature operation of our systems and the potential to produce GFs on industrial textile-scale offer opportunities for simplified and wearable optical communications.
