  • Crossing Enemy Lines – The Growing Demand For Submersible Technology

    This paper examines USSOCOM's emerging requirements for new and updated submersible equipment, with a focus on the factors that qualify such equipment for operation in combat environments. Specifically, it addresses the components most often considered the weakest link – namely, electrical cable connectors. Typically, significant changes in military equipment requirements such as this spawn innovation in the private sector. So the paper concludes by reviewing the types of equipment for which the 20-meter submersible capability may soon become standard.

Taking Your Network to 40/100G Ethernet

With the ratification of new industry standards and increased demands on data center throughput, 40/100G Ethernet will be an integral component of the next generation data center. In fact, it is already an emerging influence on how organizations plan, build and operate their existing data center architectures. In this paper, we will discuss the deep impact that this network speed transition has on data center cabling infrastructure, and the decisions that organizations will need to make to accommodate these changes.

Basics Of Power Measurement — Average Or Peak?

When setting up a test system, it’s critical to know the types of measurements you want to capture in order to select the right equipment.  In the world of power measurement, one can easily be confused by the different types of sensors and their varying measurement capabilities.  Parsing through some of the terminology can help make the selection process easier.

On The Road To Seamless Connectivity, Wi-Fi Has No Speed Limits

Consumers expect a high standard of network connectivity. Even though our global data consumption has risen from petabytes (1,0005) per month to exabytes (1,0006) per month, users do not want to experience any issues. While Wi-Fi is used to offload the cellular network, high-demand applications continue to cause strain, and smartphone manufacturers continue to pressure carriers to make network enhancements to offload data traffic. 

Overview of External Propulsion Launch System

Escape Dynamics is in the process of developing and testing its new external microwave propulsion technology that permits reusable single-stage-to-orbit space flight. This white paper discusses the new technology in detail, and gives an overview of the substantial benefits of utilizing this technology for better and more frequent space travel with 10x reduced overall costs.
