DornerWorks Case Studies
We delight in finding creative ways of applying our engineering expertise — not only to solve technical problems, but also to give our clients business solutions.
Medical Case Studies
To move large patients on the bed without risking injury to hospital staff.
How to fit a high power system into a very small footprint and still meet the thermal and other requirements of UL 60601-1.
DornerWorks developed the electronic and software system which performed analog I/O, motor control, power regulation, and control of the device. A very high density board layout was needed to fit within limited space and this meant particular care needed to be used to meet the strict heat and EMI requirements dictated by UL 60601-1 in a high power design. Through the creative application of dual-use circuits and advanced motor control techniques, the system was designed, implemented, and met the regulatory directives.
A cost effective way for physicians to control chronic back pain in their patients.
Providing the industry’s first and only radiofrequency generator able to handle up to 4 lesions simultaneously and with independent control, and the first device of its kind to do this using a full-touch screen interface.
On this project we worked closely with our client in developing the firmware which measured and controlled the impedance and thermal elements, controlled the waveform of the RF energy being delivered, provided several software components, and internationalized the user interface. DornerWorks engineering expertise allows us to help at low-level implementations, as well as at the user-interface level, for embedded device development.
Dental Practitioners needed a more scientific method of color matching veneers and crowns for their patients.
Designing a system that was capable of taking high quality images for the application of advanced color matching techniques with low cost electronics that could fit in the palm of the dentist’s hands – and be comfortable for the patient.
In order to minimize the handheld device’s advanced processing requirements, a system level approach of taking the images on the handheld device and then uploading them to a desktop PC was taken. This allowed the advanced and complex color matching techniques to be implemented with the power of a desktop computer. However, the handheld device had to take very good quality pictures and download them to the PC in a timely manner. USB was chosen as the interface, which at the time was an emerging technology. DornerWorks was critical in the development of this new high speed interface. Also, a CMOS sensor was chosen as a low cost camera device alternative over the then popular CCD imagers. DornerWorks was critical in the development of the FPGA controller for the CMOS sensor as well as moving the image data into memory via the onboard PowerPC microcontroller’s Direct Memory Access (DMA) controller.
A customer* found themselves in an undesirable position of needing a field installable retrofit on a product to avoid a general recall.
Finding a means of working with existing hardware and modifying the low level software to improve the accuracy of the device.
Developed and tested software that helped the client avoid a costly and damaging recall thereby saving them hundreds of thousands of dollars. DornerWorks can help you on not only your new product development needs, but also in modifying and upgrading your existing products.
