Laboratory Instruments for Scientific Research
We design custom electronic circuits for scientific research laboratories. Advanced temperature controlled linear amplifiers at RF frequencies is a recent example of such deliverables. We carefully gather the performance requirements by discussing the specific features and functions that the scientist needs the electronic instrument to provide. When the design is complete, assembled and tested, we perform a certification test and preserve this data for the client via screen shots of the spectrum analyzer, oscilloscope, or other appropriate measurement tools in-house.
Electronic Circuit Designs
Your specific requirements drive the layout and size of the printed circuit board that we layout. Depending on the signal types on the board, we may need heavy copper traces to carry high current, or we may thin short copper traces to minimize the resistance and inductive loading of delicate sensor signals that include micro or nano Volt signatures that must be preserved.
We have the experience and capability to switch thousands of Volts on the same printed circuit board that must include a sensitive micro-controller. This is a bit challenging due to the extremely high noise generated by the switching high voltages. However, there are proven ways to design such a PCB, and include components that absolutely isolate and absorb such noise.
A big part of what we do here is design and build working prototypes. These proof-of-concept designs may then be used to demonstrate the idea/capability to investors that wish to license or purchase your proven product. Of course, if you choose to have it manufactured yourself, this prototype is the first step to really understanding the challenges and opportunities for such a venture. Prototypes are essential in order to truly test a product idea by observing the user experience.
Technical Solutions ... 100% Successful
These exciting summaries below demonstrate our track record of taking very challenging problems and developing solutions that are truly feasible in the real world. Many of these solutions are the result of the common need to inspect materials and aerostructures with out doing any damage to the test specimen. This work is by far our favorite type of electrical engineering that we perform.
This first link summarizes the successful proof-of-concept delivery & presentation to NASA Langley of a system demonstrating the ability to detect aerostructure damage and prioritized healing in flight. The presentation received a standing ovation by 40 NASA engineers.
The second paper summarizes the successful proof-of-concept delivery of a non-destructive inspection electronic device that could detect surface and sub-surface cracks at the 25 nose-to-tail lap joints of a Boeing 737. This advanced electric design included a probe that utilized a GMR sensor and a custom induction circuit. It worked much like the common stud finder. Simply slide the probe along the joint, and the LED bargraph display would indicate the degree of the crack.
