Industrial Robotics Object Calibration System

The Industrial Robotics Object Calibration System is designed to use a six-axis industrial robot to calibrate a work object autonomously and efficiently. In addition to the industrial robot, the calibration system consists of one processing module and two measurement tools. The two tools are for calibrating the robots’ tool center point coordinates and work object coordinates, respectively. If an object is either placed on a processing stand or mounted on the robot arm, its real coordinates can have slight offsets relative to the coordinates defined in off-line programming. This system provides an efficient calibration solution that can achieve TCP calibration in 30 seconds and work object calibration in 10 seconds. The precision of the calibration results is better than 0.2 millimeters

Degranulation Response in Cytotoxic Rat Lymphocytes Measured with a Novel CD107a Antibody

Measuring degranulation through CD107a expression has become an advantageous tool for testing the functional capacity of cytotoxic cells. Such functional studies have been hampered in the rat by the lack of a suitable anti-rat CD107a antibody. In this study, we report a novel hybridoma generated by immunizing Armenian inbred hamsters with transfected Chinese hamster ovary cells expressing CD107a. The SIM1 clone exhibited specific reactivity with CD107a and measured degranulation from natural killer (NK) cells stimulated with target cells or mAb crosslinking of their activating receptors. Degranulation in IL-2-activated NK cells could also be measured, when using low effector to target ratios. SIM1 also stained activated CD8, but not CD4 T cells. This report characterizes the degranulation response in cytotoxic rat cells with a new antibody against rat CD107a

Remotely Operated Aerial Vehicles and Their Applications

This project examines relevant designs and applications of unmanned aerial vehicles (UAVs). We propose UAV design solutions, which can be refined and incorporated into emergency medical services. Mathematical and engineering concepts are used to select the design solutions. We believe that the proposed design solutions will enhance the quality of care in emergency medical services
