Abstract: A patient securing overlay includes a sheet of fabric configured to support a patient's torso on a surgical table. The sheet of fabric includes friction enhancing elements applied to at least a portion of an upper surface. The sheet of fabric is attached near its side edges to two or more side flaps that extend laterally outward from the side edges of the sheet of fabric. Each of the side flaps is attached to the surgical table at two or more attachment points. A distance between adjacent attachment points is greater than a distance between an attachment point and the sheet of fabric in order to naturally create a favorable retaining force vector angle of less than 45° between the attachment point and the sheet of fabric.

Abstract: A Multi-Purpose Dynamic Simulation and run-time Control platform includes a virtual process environment coupled to a physical process environment, where components/nodes of the virtual and physical process environments cooperate to dynamically perform run-time process control of an industrial process plant and/or simulations thereof. Virtual components may include virtual run-time nodes and/or simulated nodes. The MPDSC includes an I/O Switch which delivers I/O data between virtual and/or physical nodes, e.g., by using publish/subscribe mechanisms, thereby virtualizing physical I/O process data delivery. Nodes serviced by the I/O Switch may include respective component behavior modules that are unaware as to whether or not they are being utilized on a virtual or physical node. Simulations may be performed in real-time and even in conjunction with run-time operations of the plant, and/or simulations may be manipulated as desired (speed, values, administration, etc.).
