Removing the Risk of Concentrated Salt Solutions to Precision Dispense Pumps

IVD instrument OEMs require high accuracy pumps for dispensing reagents, wash fluids and samples. The types and concentrations of fluids dispensed by these pumps vary widely and can be excessively damaging to the internal parts of pumps. For this reason, pump designers are continually challenged to create products that can survive increasingly aggressive environments.

ASTM D4169: A Historical Perspective, plus Review and Implications of D4169-16

WESTPAK's protective package system testing professionals present a webinar focused on ASTM D4169. We begin with a historical perspective of D4169 and its origin to provide you with a background on protective package testing protocols. Then we review D4169-16 and compare it against the prior revisions. We discuss options available if your test fails the –16 revision after passing prior revisions. Live Q&A will be included during the broadcast.

A team of researchers from the Georgia Institute of Technology has developed a way to use 3D printers to create objects capable of shape change. The objects use tensegrity, a structural system of floating rods in compression and cables in continuous tension. The researchers fabricated the struts from shape memory polymers that unfold when heated. The technology could someday be used in applications ranging from space missions to biomedical devices.

Self-Learning Robot Hands Adapt to Grasp Objects

By connecting tactile sensors with intelligent software, the robot hands control their strength for a fine-touch grip that won’t damage delicate objects. (Bielefeld University)

A new grasp system with robotic hands works without previously knowing the characteristics of objects. The system, which learns by trial and error, was developed by researchers at Bielefeld University in Bielefeld, Germany. It features two hands that are based on human hands in terms of both shape and mobility. The robot brain for the hands must learn how everyday objects like pieces of fruit or tools can be distinguished based on their color or shape, as well as what matters when attempting to grasp the object; for example, a banana can be held, and a button can be pressed. The system learns to recognize such possibilities as characteristics, and constructs a model for interacting with and re-identifying the object.

Crawling Robot is Powered by Moisture

Researchers used flash-treated graphene oxide to create a crawler that moved when humidity was increased. Switching the humidity off and on several times induced the crawler to move 3.5 millimeters in 12 seconds, with no external energy supply. (Credit: Jilin University)

Using an off-the-shelf camera flash, researchers at Jilin University, China, turned an ordinary sheet of graphene oxide into a material that bends when exposed to moisture. They then used this material to make a spider-like crawler and claw robot that move in response to changing humidity, without the need for any external power.

Technical Webinar Series from the Editors of SAE: Advances in Unmanned System Propulsion

In Conjunction with SAE

The development of new propulsion technologies has been the focus of R&D looking to provide the functionality needed for unmanned aircraft systems, including vertical takeoff and landing, long endurance, stealthy operations, and stability in hostile environments. Their development also incorporates advances in scalability, re-configurability, and extensions that host functions to legitimate business opportunities such as goods delivery, agriculture, firefighting, news gathering, and military operations. Success means reduced operation and maintenance costs as well as less complexity, but it also brings higher functioning systems.

Technical Webinar Series from the Editors of SAE: Connected Vehicles & Jobsites

In Conjunction with SAE

Fleet owners have been deploying telematic solutions for some time, but connectivity is still just beginning to move from early adopters to mass market. Connectivity is providing more owners and operators a broad range of benefits, prompting a surge of developments by OEMs and suppliers. Chief among those benefits are safer, more efficient, and productive vehicles and worksites, both on- and off-highway. Yet technical challenges remain with development and testing of V2X communication, cybersecurity, and how to best utilize Big Data.
