A mandrel position analyzer () in an imaging device () includes a head stock () for a first side of the mandrel; a tail stock () for a second side of the mandrel; a first encoder () attached to the head stock adapted to measure first signals wherein the first signals are generated by movement of the mandrel; a second encoder () attached to the tail stock adapted to measure second signals wherein the second signals are generated by movement of the mandrel; an analyzer () which compares measured results of the first signals and results of the second signals; and if the measured results do not match generating an abnormal state of the mandrel signal alarm ().

Detecting an unsecured state of a mandrel

A method for analyzing a mandrel () operation in an imaging device () includes installing the mandrel into the imaging device; securing the mandrel between a head stock () and a tail stock (); attaching a first encoder () to the head stock and a second encoder () to the tail stock; rotating the mandrel; reading signals from first encoder; reading signals from second encoder; comparing the first results and the second results; and if the first results do not match with the second results stopping the imaging device.

An electronic circuit includes a plurality of programmable components connected in an electronic chain. An interface is adapted to connect the programmable components to an external controller wherein the controller is adapted to program the programmable components. A component isolation element is connected to the interface at an input end and to the electronic chain of the programmable components at an output end wherein the isolation element is adapted to isolate one component of the programmable components from the electronic chain and wherein the one component is a safety component.

Safety component in a programmable components chain

A method for a singular programming a programmable component in an electronic circuit includes providing a plurality of programmable components connected between each other in an electronic chain arrangement; providing an interface adapted to connect the programmable components to an external controller wherein the controller is adapted to program the programmable components; isolating and programming a safety component by setting an output pin in the safety component to logical state zero at first power up of the electronic circuit and logical state zero causes input and output data lines from the interface to be connected just to the safety component; and setting the output pin in the safety component to logical state one wherein the logical state one causes input and output data lines from the interface to disconnect from the safety component and connect to the electronic chain of the plurality of programmable components excluding the safety component.
