Motion Control Processor

The Magellan motion control processor from Performance Motion Devices, Inc. (Lincoln, MA) comes in one, two, three, and four-axis chip set versions that can control DC brush, brushless DC, micro stepping, and pulse & direction motors. The motion controller requires only an external amplifier to be functional. It is driven by a host using an 8 or 16-bit parallel bus, CANBus 2.0B, or an asynchronous serial port. User selectable profiling modes include Scurve, trapezoidal, velocity contouring and electronic gearing. Servo loop compensation utilizes a full 32-bit position error, PID with velocity and acceleration feedforward, integration limit, and dual bi-quad filters for sophisticated motion control of complex loads.

I/O Module

Holjeron (Tualatin, OR) has introduced the Aqua Series I/O modules for DeviceNet™. The module is designed for outdoor use in temperatures as low as -30 C and as high as 70 C. They are available in four analog input, four analog output, eight individually configurable digital I/O, and four frequency input versions. The modules are fully potted and sealed to NEMA 6P and IP68. They are suited for construction vehicles, petrochemical, wastewater and other process industries where robust and rugged DeviceNet™ I/O is needed, without the need for additional enclosures. The modules are protected against shock and vibration, while delivering fast response times and high resolution.

X-Ray Camera

Andor Technology, South Windsor, CT, offers the iKon-M x-ray camera available in two models: the DO and DY. The DO interfaces with vacuum chambers, and the DY is a standalone camera with a beryllium input window. The cameras offer a low-read noise floor, high QE across the x-ray, XUV, and EUV energy ranges, and negligible dart current with thermoelectric cooling to -90°C. Readout speeds of up to 2.5 MHz enable faster frame rate imaging of dynamic processes.

CCTV Conversion Software

Avocado Security, Fairfax, VA, has introduced Avocado Express 2.0, a security and business intelligence optimization platform that provides security images by taking the video images from surveillance cameras and translating them into intelligent business data and statistics. It can convert video images from existing security equipment from multiple vendors and translate the images into usable data. The technology can instantly send alerts about misaligned, disconnected, or malfunctioning security equipment. The platform can integrate an organization’s security platform across multiple locations, and showcase the security details of each location by generating daily, weekly, and monthly status reports.
