We present the design and the mechanical and thermal performances of a prototype rotational mechanism using a superconducting magnetic bearing (SMB) for a space compatible polarization modulator. The rotational mechanism consists of an SMB with an optical encoder and a three-grip mechanism that holds a levitating rotor until a high-temperature superconducting array (YBCO) cools down below its critical...
Continuous monitoring of physical activity for diabetic individuals provides important information regarding energy expenditure. This device makes use of both heart rate sensing and full body acceleration to measure physical activity. Energy expenditure is calculated using an algorithm which determines the amount of activity occurring. The output is displayed in carbohydrates to allow for better informed...
In today's content delivery solutions, service delivery and control are still tightly coupled, a service typically being delivered to the same device that controls the session. We present a solution that was designed with the goal to decouple service control and delivery. Using our approach, multimedia streaming services can be delivered to off-the-shelf DLNA devices in visited networks. The service...
