Abstract: An isolation resistance monitoring system for a high voltage direct current (DC) system includes a plurality of high voltage systems including a first high voltage link and a second high voltage link, a plurality of isolation monitors operably coupled with each of the first high voltage link and the second high voltage link to detect isolation resistance data, and a controller including data processing hardware configured to execute an isolation monitoring algorithm. The data processing hardware is also configured to execute an isolation function based on the isolation resistance. The isolation monitoring algorithm is configured to determine an isolation resistance level of each of the first high voltage link and the second high voltage link based on the isolation resistance data.

Abstract: An apparatus and method to thermally form a smooth profile tip on a polymer tube such as a catheter. The process employs a metal mold that contains the desired form. The polymer tube is inserted partially into a cool mold which is heated sufficiently to soften the plastic. The tube is then forced further into the mold until the form is completed. The tube is gripped with a clamp and inserted into the mold using a motorized linear stage. In addition to time and temperature control, the apparatus and method adds load cell based force feedback and a motorized linear stage with speed control and encoder based position feedback. The control software provides a multi-step process flow where each step includes user programmable force, distance, speed, temperature, and time. Users can define each parameter in each step to produce a desired result.

Abstract: A process for manufacturing a cyclic peptide which comprises providing a cyclic peptide bonded to a Merrifield-type resin and cleaving the cyclic peptide from the Merrifield type resin by transesterification.

Abstract: Radiation curable resin compositions are provided that are most useful in stereolithography. A radiation curable resin includes a base oligomer, a cross linking agent, a reactive solvent, and an anti-nucleation agent. The resin after curing provides a solid product that has improved physical properties.
