Abstract: A sublimation/distillation apparatus including a crucible with an open end, a heating device thermally coupled to the crucible, an actively cooled collection substrate disposed above the open end of the crucible, and a vacuum chamber housing the crucible, the heating device, and the actively cooled collection substrate.

Abstract: An apparatus for generating medical isotopes provides an annular fissile solution vessel surrounding a neutron generator. The annular fissile solution vessel provides for good capture of the emitted neutrons and a geometry that provides enhanced stability in an aqueous reactor. A neutron multiplier and/or a neutron moderator may be used to improve the efficiency and control the criticality of the reaction in the annular fissile solution vessel.

Abstract: An apparatus for use with an encoder feedback device includes a comparator, a counter, and a prediction unit. The encoder feedback device is coupled to rotate with a rotating load and operable to generate at least one feedback position signal indicative of movement of the rotating load. The comparator is operable to receive the feedback position signal and generate a first position signal including a plurality of edges based on the feedback position signal. The counter is operable to receive the first position signal and count the edges to periodically generate position values at a predetermined update interval. The prediction unit is operable to receive a position data request at a first time and predict a position of the rotating load at the first time as a function of at least a subset of the position values generated prior to the first time and a misalignment between the first time and the predetermined update interval to generate an aligned position signal.

Abstract: An electronic line shaft includes a motor drive and a processing unit operable to execute a wizard for configuring the motor drive. The wizard is operable to receive mechanical characteristic data associated with the motor drive, determine a noise parameter based on the mechanical characteristic data, and determine at least one control parameter of the motor drive based on the noise parameter.

Abstract: A method and assembly for synchronizing machine operations, the assembly comprising a reference generator for generating a speed reference signal and a position reference signal, a plurality of slave units, each slave unit including, a mechanical device, a separate motor linked to and driving the mechanical device and a separate unit controller for controlling the unit motor, the unit controller receiving and using the reference signals to control motor operation and a synchronizer receiving the reference signals from the control signal source and simultaneously providing the reference signals to each of the slave unit controllers for use in controlling operation of the motors in a synchronized fashion.
