BrainStem® Technology
Post date: 8 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: 8 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 Ranging Model Comparison
Post date: 10 years 6 months ago
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.

The Sharp family of infrared ranging modules
These 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...
Driving High Power Loads with H-bridge
Post date: 11 years 7 months ago
high power loads using low-level voltage signals
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/...
Description of Pulse Width Modulation blog post
Post date: 12 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.

ElectroMotive Force
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...
