RS-485 (EIA-485) serial interface pinout and wiring EIA-485 (formerly RS-485 or RS485) is an OSI Model physical layer electrical specification of a two-wire, half-duplex, multipoint serial connection. The standard specifies a differential form of signalling. The difference between the wires? MIMO Beamforming and Its Impact on Testing TD-LTE Lobes created by simple beam steering. Recently, both wireless and business media have cast a spotlight on TD-LTE. At a conceptual level, TD-LTE is easily understood. It is simply LTE with uplink and downlink multiplexed in the time domain rather than the frequency domain.

Allegro Motor Drivers Allegro offers an industry leading portfolio of motor driver and controller ICs for brushless DC, brush DC, and stepper motors. Product architectures vary from highly-efficient internal DMOS drivers to MOSFET controller ICs suited for a wide variety of motor applications. Coupled with a strong system level expertise, Allegro’s motor driver IC portfolio provides the user with a high-performance, leading edge and reliable motor control solution. Allegro's BCD (bipolar, CMOS and DMOS components) technology allows for a wide range of features that is well suited for today’s demanding motor control applications. Allegro motor driver ICs can be found in a number of demanding markets, including automotive, industrial and office equipment. Our products are found in motor driver applications such as automotive pumps and blowers, electronic power steering (EPS) systems, printers (ink-jet and laser) and a variety of cooling fan applications.

Windows 7 Supports Login Screen Customization Without 3rd Party Software, How-to Instructions Inside Did you know Windows 7 comes with a built-in Registry tweak which allows you to easily customize or change the background image of Windows login screen (aka Welcome Screen)? Yes, using this secret feature you can set any of your favorite wallpaper as Windows 7 login screen background without using any 3rd party software. Want to know how to do that? Just follow these simple steps: 1. Why you should upgrade to VMware Workstation 7 Software companies release upgrades, it's a fact of technology life. Sometimes the older version works just fine, other times upgrading can provide benefits that are more than worth the upgrade. Upgrading to Workstation 7 offers both increased performance and Windows 7 support, both of which are lacking in Workstation 6. Further, if you've already upgraded to Windows 7 and find that Workstation 6 is no longer functional, upgrading Workstation could be your answer. When you register, my team of editors will also send you alerts covering all areas of VMware, such as implementing VMware-related virtualization technologies for server consolidation, disaster recovery and backup strategies, management and performance, VM migration and more.

Yield Sensitivity Analysis of A Low Pass Filter - ADS 2009 Update 1 - Agilent EEsof Knowledge Center Location: $HPEESOF_DIR/examples/Tutorial/yield_sensitivity_prj Objective This example shows the yield analysis using a low pass filter as an example. The data display contains some equations useful in the yield analysis. Setup AVR Motor Applications Get Started We'll tell you all you need to know to start evaluating and working with this product. Atmel® has more than 15 years' experience with driver ICs for DC motors. We supply products at a high-volume for a variety of common body electronic applications, including mirror control and flap control in HVACs. Although the Atmel driver ICs are equipped with a variety of types of driver stages, they all share the same protection features – short-circuit protection, temperature warning and switch off, low voltage protection, and open load detection – all of which are a must for automotive electronics.

Tweet Content From Any Website Using Right-Click In Chrome TweetRight is a Chrome extension, which allows quickly tweeting images, links, webpages and selected text from any part of a website. Just highlight the text and select Tweet This via right-click context menu. This enables users to tweet any selected context from a website that may not be supported by a tweet box. For example, lets say you come across an interesting article which you wish to share on Twitter. This can be easily done by simply selecting any part of the article (e.g. title) and tweeting it from the context menu.

How to Start a Startup March 2005 (This essay is derived from a talk at the Harvard Computer Society.) You need three things to create a successful startup: to start with good people, to make something customers actually want, and to spend as little money as possible. Most startups that fail do it because they fail at one of these. A startup that does all three will probably succeed. And that's kind of exciting, when you think about it, because all three are doable. Sensitivity Analysis, Basic Example - ADS 2009 Update 1 - Agilent EEsof Knowledge Center Location: $HPEESOF_DIR/examples/Tutorial/sensitivity_ex1_prj Objective This project contains two examples that simulate the sensitivity (normalized and unnormalized) of a trivial circuit (a voltage divider.) The circuit is trivial so it is easy to calculate the sensitivity analytically.

Jones on Stepping Motors Index Abstract This tutorial covers the basic principles of stepping motors and stepping motor control systems, including both the physics of steppers, the electronics of the basic control systems, and software architectures appropriate for motor control. Introduction Stepping motors can be viewed as electric motors without commutators. Typically, all windings in the motor are part of the stator, and the rotor is either a permanent magnet or, in the case of variable reluctance motors, a toothed block of some magnetically soft material.
