Nelson Research has full lab facilities allowing for the development and debug of electronic products. The lab is equipped with Oscilloscopes, Meters, Soldering stations, Emulators, Device programmers, and computer systems. We have CAD capabilities including Protel and Orcad for schematic capture as well as Printed Circuit Board Layout. We can also provide Spice Simulation using ISSpice. Nelson Research has been a member of the Boston IEEE Consultants Network and is a founding member of the National IEEE Consultants Network. We are listed with Microchip and Z-World as consultants for their products and we were one of a select few confirmed as achieving Master Consultant Status (Gold Level) with Microchip. We offer design consulting for the full line of Microchip embedded microprocessors as well as development of systems using the board level products from Z-World. Through cooperative agreements with associates we can provide mechanical design and fabrication work to allow us to provide any part of your project from concept, to prototypes, through initial shipment of finished products. We have worked on the development of a wide range of products including automotive aftermarket gauges, radar detectors, alarm systems, strobe lights, machine tool control systems, and medical instruments. We have also designed Test Equipment for production environments. Some of this test equipment interfaced with IBM Compatible computer systems running custom software written in HP-VEE by Nelson Research.
This Battery charger is a smart charger that conditions and charges a nickle cadmium battery pack. It senses temperature of the cells and controls the charging characteristics to allow for a fast charge with proper termination of charge while keeping the pack safe from overcharging or exceeding safe temperature characteristics. There are currently several hundred of these battery pack systems in use internationally keeping portable Unix based computer systems running in mobile environments as supplemental battery backup systems. We have also designed battery charging systems for Nickel Metal Hydride and Lithium Ion battery systems.
This interface board is a 4 channel board to connect between standard RS232 signal levels and a 5 volt hardware UART or signal from an embedded microprocessor. The board is available as a 2 channel interface or as a 4 channel interface. Contact Nelson Research for pricing and availability.
