Overview

The Instrument Development Laboratory Core (IDL) meets the research instrumentation and engineering needs of CHDD Research Affiliates and other IDDRC Core units involved in behavioral and biomedical research in acquiring, constructing, installing, and maintaining research instrumentation systems. In general, Research Affiliates require engineering instrumentation consultation when planning, prototyping, piloting, running, and completing and summarizing projects. In addition, they require maintenance engineering support and support on an urgent basis to recover from experimental system failure in ongoing experiments.

The overall objectives of the IDL core are as follows:

  • Design and construct research instrumentation
  • Provide hardware and software systems
  • Provide maintenance and repair services
  • Install and test commercial instrumentation
  • Advise on instrumentation, experiment design, data acquisition, and data reduction
  • Advise investigators about and test commercially available instruments
  • Inform and advise on security and safety issues
  • Evaluate environments in laboratory facilities
  • Assist in the development of research grant and contract applications
  • Support the dissemination and publication of research methods and results

The types of instrumentation that have been provided by IDL include:

  • Physiologic stimulating and monitoring equipment
  • Audio, video, and medical imaging recording and analysis systems
  • Props (modified toys) for learning and behavioral research with children
  • Electrical, chemical, and environmental control systems
  • Monitoring and measuring equipment
  • Computer, electronic, and electromechanical devices for managing experiments and systems for gathering, managing, analyzing, and archiving research data

Computer System Development

IDL is experienced in the development of software for:

  • Timed/monitored stimulus presentation with data collection directly into an Access database or custom-format data file
  • Presentation of stimuli with precise timing and/or visual specifications
  • Demanding data acquisition tasks
  • Remote monitoring/control of experimental systems over the internet
  • Child-friendly task-assessment software
  • Video monitoring, recording, and coding

Key software in the IDL includes the LabVIEW Professional Development System for the rapid creation of sophisticated and user-friendly PC-based systems.

Some applications require ready portability and more modest computing power. Such cases suggest the use of a microcontroller, a single chip comprising many of the basic functions of a computer. We are facile with the Basic Stamp microcontroller development system. Like LabVIEW, this is a "high-level" programming environment allowing software to be developed quickly and changed easily.

Electronics/Optics Space

This space is equipped with digital oscilloscopes, test computers, an electrical safety test system, a portable sound/vibration test system, a high-resolution photometer system, video system components, and an electronic EEG/EKG simulator. Portable test equipment and other tools are also available for field-testing and repair of video, computer, and other electro-mechanical systems. The IDL maintains an inventory of commonly used electronic and mechanical parts, devices, and materials for use in repair of existing systems and for future projects and has access to stores in other nearby departments at the University of Washington.

Machine Shop

This shop includes a metal cutting lathe, mill, large and precision drill presses, band saw, metal shear, sander, grinder, router, cordless drills, and an array of hand tools. Nearby are shared equipment comprising a table saw, carpentry tools, and gas and arc welding systems. We maintain a close relationship with other instrumentation facilities on the University of Washington campus including the Scientific Instruments Division located across the street in the UW Health Sciences building. The IDL also has collaborative relationships with research shop facilities in the Departments of Bioengineering, Chemical Engineering, Electrical Engineering, and Ocean and Fisheries Sciences. Often these facilities collaborate in the creation and application of electrical, mechanical, and optical instruments. The IDL staff is skilled in system design and fabrication of parts and systems. IDL can design and construct PC boards and microcircuits, as well as metal panels and enclosures to make complete electronic devices. IDL staff members are skilled in welding, sheet metal fabrication, cabinetry, plumbing, plastic forming and casting, and glass blowing. IDL staff members are also experienced in the development of robotic and electromechanical systems, electrochemical systems, membrane transport models, ultrasound and acoustical systems, optical imaging, and optical data communication systems. Considerable experience in computer programming including computational simulations, experimental control, data analysis, image handling and processing, output synthesis, database development, and statistical analysis further facilitates support for affiliates.
