Introduction to computed tomography (CT) medical imaging

rsdio tipped us to an app note on a computed tomography (CT) medical imaging. This tutorial explains how computed tomography (CT) imaging systems generate 3-D images of internal body structures. The high-end spiral CT technique is explained, as is the method by which light collected from photodiodes is processed into an electrical signal and eventually […]

App Note: LEDs allow new remote-controlled lighting applications

A remote-controlled lightning applications: One benefit LEDs offer in general lighting applications is that they are easier to control remotely. This application note describes a remote-controlled architectural or street-lighting system and describes how to implement power-line or wireless communications control of a lighting system. Thanks for the tip rsdio!

App Note: Overview of industrial motor control Systems

An overview of industrial motor control systems: This overview of industrial motor controls highlights the differences and subsystems for DC motor, brushless DC, and AC induction motors. An in-depth analysis of critical subsystems focuses on monitoring and measuring current; sensing temperature; sensing motor speed, position, and movement; monitoring and controlling multichannel currents and voltages; and […]

Introduction to magnetic resonance imaging (MRI)

rsdio tipped us to an app note on magnetic resonance imaging (MRI). This tutorial explains how magnetic resonance imaging (MRI) systems use the reaction of hydrogen atoms moving in a magnetic field to yield a detailed medical image. The types of magnetic fields typically used are described. The note explains why today’s higher resolution MRI […]

App note: Digitally controlled DC/DC converter

A digitally controlled DC to DC converter: You can easily add margining capability (digital adjustment of the output voltage) to a DC/DC converter by adding a 2- or 4-channel, I²C-adjustable current DAC (DS4402 or DS4404) at the converter’s feedback input. Because each DAC output is 0mA at power up, the extra circuitry is transparent to […]
