Abstract: A system for remotely controlling a peripheral device, the system comprising a management server having a processor and memory, the memory comprising computer-readable instructions that, when executed by the processor, cause the processor to: (i) receive a command to control the peripheral device over a network from an originating gateway device; (ii) process the command to determine a destination gateway device for the command, the destination gateway device being connected to the peripheral device; (iii) select between one of a first communication protocol and a second communication protocol based upon one of a stability and latency of a network connection between the management server and the destination gateway device; (iv) routing the command to the destination gateway device over the network using the selected one of the first communication protocol and the second communication protocol.

Abstract: A portable flow model for simulating ultrasound studies contains an injection point, a pump, a choke, a valve, a study chamber equipped with a study window and another choke that is used as resistance. These individual components are connected to one another in a closed circuit by a tube system.
