Five Factors to Consider when Selecting an Overcurrent Protective Device for an Electric Vehicle System to Ensure Safe and Reliable Performance

In electric and hybrid vehicle applications, electrical systems are often pushed to their limits. Aggressive current pulses, combined with high temperatures and vibration profiles, push the limits of electrical system reliability. When selecting an over-current protection device (OCPD), care must be taken to account for these complex variables while still providing a system that is safe and reliable. This article will discuss five critical and often overlooked factors in OCPD selection in EV applications in order to ensure safe and reliable system performance.

Selecting the Right Standard High-Voltage Power Supply

High-voltage power supplies drive a broad range of applications across diverse segments, including semiconductor, scientific, medical, industrial, and more. Designed to deliver stable supply voltages at 50 V and up, the power supplies, comprised of sophisticated components and specialized materials, must carefully manage the high voltages and associated effects, for example, corona and arcing. For systems developers choosing standard high-voltage power supplies, the specialized nature of high-voltage power calls for a power supply selection process that reflects the unique characteristics of the high- voltage power supply and its operation.

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.

3D Printed Tensegrity Object Can Change Shape

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

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

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.

Will solar paint catch on?

In today's lead INSIDER story, researcher Kourosh Kalantar-zadeh said of his "solar paint": "It will be widespread. It is a technology that can shift the energy economy to a hydrogen economy. This disruptive concept has the potential to change many of the current technologies as we know them." What do you think? Will solar paint catch on?
