Cable Anatomy I: Understanding the Speaker Cable
How big should the conductors be? The required size (or gauge) of the conductors depends on three factors: (1) the load impedance; (2) the length of cable required; and (3) the amount of power loss that can be tolerated. Each of these involves relationships between voltage (volts), resistance (ohms), current (amperes) and power (watts). These relationships are defined with Ohm’s Law. The job of...
متن کاملWhen it breaks , it breaks
Dependencies among software projects and libraries are an indicator of the often implicit collaboration among many developers in software ecosystems. Negotiating change can be tricky: changes to one module may cause ripple effects to many other modules that depend on it, yet insisting on only backwardcompatible changes may incur significant opportunity cost and stifle change. We argue that awar...
متن کاملIonic cable
This paper demonstrates a new type of interconnects to fulfill the primary function of axons: transmitting electrical signals over long distances and at high speeds. The interconnect, which we call ‘‘ionic cable’’, uses ions to transmit signals, and is built entirely with soft, elastic materials—elastomers and gels. The ionic cable is highly transparent, and remains functioning after being stre...
متن کاملAutomated Cable Preparation for Robotized Stator Cable Winding
A method for robotized cable winding of the Uppsala University Wave Energy Converter generator stator has previously been presented and validated. The purpose of this study is to present and validate further developments to the method: automated stand-alone equipment for the preparation of the winding cables. The cable preparation consists of three parts: feeding the cable from a drum, forming ...
متن کاملPassive Intermodulation Distortion in Connectors, Cable and Cable Assemblies
Introduction: Although not a new problem and well known to the satellite communications and microwave trunking industries, until the use of cellular phones became widespread, Passive Intermodulation Distortion (PIM) was of little concern to the connector designer. Until five years ago, most connector engineers had never heard of the phenomenon. Now, due to the frequency plans of today’s modern ...
