A machining system having a first machine tool assembly with a first workpiece holder and a first machining unit for performing a processing operation on a workpiece held by the first workpiece holder, and a second machine tool assembly having a second workpiece holder and a second machining unit for performing a processing operation on a workpiece held by the second workpiece holder. The gaming machine utilizes a combination of symmetric and asymmetric encryption that allows a single gaming machine to securely communicate with a remote server using a public network. More specifically, the systems and methods can facilitate optimizing probabilities that are assigned to the training data for later use in machine learning processes, for example. In particular, the level detecting device is suspended on the mounting means via a resilient assembly.
