Setting up product manufacturing involves many complicated systems and processes. In order to produce millions of devices a month, companies need to massively scale these systems. Yet this scale is in direct conflict with fast product changes and time-to-market for "the next big thing". Major...

BrainStem® Technology

Post date: 6 years 3 months ago
Acroname's BrainStem® technology is a foundational tool for bridging the gap between hardware and software systems. BrainStem controllers gather and relay peripheral information to other systems, which may be a host computer, additional microcontrollers or an array of sensors and testing equipment...

Mobile Diagnostics System blog post

Post date: 6 years 5 months ago
Today's mobile devices continue to integrate more features and functions into ever smaller packages. Features usually win over battery life during the design phase. In order to help quantify and develop test methods, Acroname was contracted by a major cellphone manufacturer to design a mobile...
Sharp Infrared Ranger Comparison

Sharp Infrared Ranging Model Comparison

Post date: 8 years 6 months ago
INTRODUCTION Sharp infrared ranging modules boast a small package, very low power consumption and a variety of output options. In order to maximize each sensor's potential, it is important to understand how these types of IR sensors work, their effective ranges, and how to interface to them....
Linearizing Sharp Ranger Data

Linearizing Sharp Ranger Data

Post date: 8 years 8 months ago
INTRODUCTION The Sharp family of infrared ranging modules are used extensively for robotics and automatic distance measurement applications. Unfortunately, the output of these sensors are inherently non-linear. In other words, a big change in output voltage does not always indicate a big change in...
Driving High Power Loads

Driving High Power Loads with H-bridge

Post date: 9 years 7 months ago
OVERVIEW A common automation system requirement is to drive or actuate high power loads using low level voltage signals. Motors, solenoids, relays and capacitive loads can be actuated with appropriate circuitry that is only possible using small current/voltage combinations often found in embedded...
Description of Pulse Width Modulation

Description of Pulse Width Modulation blog post

Post date: 10 years 3 months ago
PWM (Pulse Width Modulation) refers to the concept of rapidly pulsing a digital signal on a wire. Along with many other uses, it can be used to simulate a varying static voltage. PWM is commonly used for driving motors, heaters, LEDs or lights in varying intensities or speeds. TERMINOLOGY Period...
Back-EMF Motion Control Feedback

All About Back-EMF Motion Control

Post date: 10 years 7 months ago
INTRODUCTION Electromotive force (EMF) refers to the voltage generated by a spinning motor. Measuring this voltage in order to determine the rotational speed of a motor is commonly called Back-EMF since the voltage tends to "push-back" against the circuit driving current into a motor's windings....
Reading a Photoresistor Asynchronously

Reading a Photoresistor Asynchronously blog post

Post date: 11 years 11 months ago
OVERVIEW Photoresistors are used in many applications because they either increase or decrease in resistance depending on the amount of light.  A common application for photoresistors is the triggering of an event when the light passes a certain point.  This example demonstrates the use of a...
