Specifying Actuators for Heavy-Duty Packaging Applications

The task of selecting, sizing and applying linear actuators involves many variables, from stroke length and duty cycle to precision and accuracy requirements. Ultimately, matching the right actuator to the intended application requires a close look at all of the specifications involved and then working within the project’s performance, time and budget constraints. Certain manufacturing operations are more rigorous than others, with end-of-line packaging applications among the most demanding when it comes to linear actuation. Activities such as palletizing, case packing, cartoning and lane diverting require strong and reliable motion components. What does a design engineer or system integrator need to know when selecting actuators for these heavy-duty packaging operations? Here we take a detailed look at some of the most important aspects to consider.

Bench Top Testing of Electromechanical Devices Using a 105-AVT Angular Vibration Table

This paper is directed to developers of small electromechanical devices and systems including sensors, transducers and precision hardware assemblies that need to be tested in vibrating environments. The Acutronic 105-AVT Angular Vibration Table produces high fidelity angular vibration over a wide frequency range and serves as a test platform for stimulation and performance verification during development and/or small lot production. The compact form factor of the Acutronic 105-AVT makes this angular vibration table especially suited for bench top testing of inertial components and integrated strap down systems based on MEMS technologies. Traditional inertial devices and non-inertial devices have been tested with great success.

Optimizing Closed-Loop Control in Hydraulic Motion

Performing closed-loop control of hydraulic servo systems is often more challenging than controlling servomotor systems. The main reason is that hydraulic systems use compressible oil to move the actuator. Because of this, a hydraulic system can be modeled as a mass between two springs, where the piston and the load is the mass, and the oil on both sides of the piston represents the two springs. In contrast, servomotor systems are easier to control because there is basically only the inertia of the motor and the connected load to be dealt with.

Enabling Microliquid Chromatography by Microbead Packing of Microchannels

The microbead packing is the critical element required in the success of onchip microfabrication of critical microfluidic components for in-situ analysis and detection of chiral amino acids. In order for microliquid chromatography to occur, there must be a stationary phase medium within the microchannel that interacts with the analytes present within flowing fluid. The stationary phase media are the microbeads packed by the process discussed in this work. The purpose of the microliquid chromatography is to provide a lightweight, low-volume, and lowpower element to separate amino acids and their chiral partners efficiently to understand better the origin of life.

Heart Pump with Behind-the-Ear Power Connector

One-third of patients with heart pumps develop infection at abdominal connection. Cardiac surgeons and cardiologists at the University of Maryland Heart Center are part of a multi-center clinical trial evaluating the efficacy of powering heart pumps through a skull-based connector behind the ear. The pumps, called left ventricular assist devices (LVADs), support the heart’s main pumping chamber, the left ventricle. LVADs are implanted in the chest and powered with external batteries. Typically, these devices, which are used for patients with severe heart failure, are powered through an electrical cord connected at the abdomen, where potentially deadly infections can develop.
