Engineering & OEM Services
MDs, DOs, and NPs across primary care and internal medicine rely on RJL Quantum analyzers as a critical tool for the modern shift toward preventative, lifestyle-focused care. Featured in over 1,000 peer-reviewed research articles and registered with the FDA as a Class II Medical Device, Quantum analyzers deliver the kind of objective, repeatable body composition data that supports both clinical decisions and patient conversations.
OEM Development
From concept to finished product, RJL Systems has developed basic concepts and ideas into new hardware and software products since 1979. We specialize in engineering and assembly electronic solutions for both large and small companies. Previous clients include machine-tool, printing, automotive, transportation, and medical device companies.
EXAMPLES OF OUR WORK
Where We Have Been
- Ultra high-speed inkjet printing interface: Developed for the George F. Valassis Company to secure coupons found in newspaper inserts. In addition, a porous air bearing was developed that greatly reduced paper ink smears when using high-speed web presses.
US Patent 5,423,468 - Reliable absolute positioning using brushless resolvers: Developed for the F. Joseph Lamb Company. This concept is used today to monitor each revolution of large stamping presses for the automotive industry.
US Patent 4,360,889 (11/23/82) - Stable signal conditioning for small OEMs: Products for small OEMs that require extremely stable signal conditioning (LVDTs, load cells, and strain gauges) in hostile environments using constant current low frequency carrier techniques.
- Body composition analysis using a 50 kHz carrier frequency: RJL developed the original concept in the 1980s and received FDA clearance in 1986. This concept is used today on popular body composition scales found in many retail stores.
US Device Patent 6,631,292 (11/7/03) - Porous nail interface: Prevents artificial nail extensions from lifting off the natural human nail.
US Patent 5,638,835 (6/17/97)
WHAT WE DO
Where We Are Today
We design and manufacture products using both through-hole and Surface Mount (SMT) components, using a variety of microcontrollers, to meet your cost and performance requirements. We can design and build advanced instrumentation and electronic solutions for any industry.
From basic engineering, assembly, and testing of SMT and through-hole circuit boards to complete turn-key instruments, systems, and software — we can do it all.
From initial consulting to final assembly, RJL Systems will work with your company to design, create, and manufacture the tools and components it needs.
Processor Module
This processor module incorporates a high-speed bipolar 16-bit ADC, an isolated power supply, isolated high-speed serial communication, and a high-contrast LCD display.The processor board can easily be interfaced with a wide selection of analog sensor modules for a simple, low-cost embedded OEM system. Optional signal conditioning modules include LVDTs, load cells, infrared sensors, and safe biological interfaces. Power source options include a single 9-volt battery, three AA batteries, or 12-volt mains.
BIA Module
This Bioelectrical Impedance Analysis (BIA) module measures resistance and reactance vectors at 50 kHz with 0.1 ohms of resolution. This BIA technology is the basis of all RJL Systems body composition products and is available to any OEM that wishes to incorporate it into present and future designs.
The BIA module can also be modified for improved sensitivity (0.01 ohms) without sacrificing signal-to-noise ratio. It is an ideal solution for measuring blood flow using pulse volume techniques, such as cardiac output and limb blood flow (series and parallel plethysmography).
