IoT device, gatekeeper, and Registrar Server (or DNS) sharing information about the relationship between the real IP address and virtual IP address.

A Simplified EIT system with 4 sources, applying current simultaneously to the body and measuring the voltage on the electrodes. Each source has a parallel impedance and the body is connected to virtual ground using an additional electrode to address any current injection mismatch.

Virtual machines are denoted by cyan boxes and software containers are denoted by green boxes. The left stack is a Type-2 virtual machine (VM) which uses a hypervisor to emulate the guest OS. The application software, dependences, and the guest OS are all contained inside the VM. A separate VM, dependencies and guest OS are required for each application stack that is to be deployed. The middle stack depicts Docker container software on a Linux host. Docker uses the host Linux system and packages the application and dependencies into modular containers. No VM is necessary and the OS resources for the two application stacks are shared between different containers. The right stack depicts Docker on a non-Linux system. Because Docker requires Linux, a lightweight VM with a mini-Linux Guest OS is necessary to run Docker and encapsulate the software containers. This still has the advantage that only a single VM and Guest Linux system is required regardless of the number of containers.

'Reaching' Task. A) View of 'Reaching' scene. Each practice block contains 20 cubes (1 cube = 1 trial) presented in relation to each participant's shoulder position. A "virtual hand" corresponds to the location and movement of the paretic hand via a magnetic marker placed either in the palmar surface of a glove or directly onto the dorsum of the hand at the 3^rd metacarpal head. Both visual and auditory feedback indicates successful collision of the "virtual hand" with a cube. B) Interface for practice trial configuration. Pitch angle, yaw angle, and percentage of arm length (distance from the acromion to the radial styloid with the elbow extended) were chosen for each cube within a practice block. Practice blocks were designed to address reaching ability using arm lengths ranging from 10% to 120%. A similar interface was used to develop 'Ball Shooting' practice blocks.
