About Us

dxdt Engineering and Research was founded in 2004 by Dr. Christopher Hekimian of Germantown, MD.  The name "dxdt" is intended to represent an incremental advancement in the technological state of the art within an incremental period of time. dxdt has remained true to its name by being a small company with a history of patented concepts and new products. Originally, dxdt products and services addressed a wide range of sectors, including defense, homeland security, home electronics and health.  Currently, dxdt is focused on two main products and associated services. Dxdt has developed an inexpensive software product to replace paper Amsler grids for retina-health patients.  


This product is a first-of-its-kind quantitative retina health test grid  developed in cooperation with physicians from the National Eye Institute of the U.S. National Institutes of Health.  It not only measures retina health, it maintains a history of it that can be used for monitoring of retina health and prognostic and research purposes.

Another product we are currently advancing is a system for providing meaningful broad scope sensory stimulation for neurological patients and individuals under palliative care, suffering from dementia, or at risk of Alzheimers.  dxdt works with family members to collect and provide digitized photographs, music, voice messages and other forms of personalized media to provide stimulation and entertainment to the ailing.  The system has many other features that can be expected to help in the neurological healing process and retard the onset of dementia.

Please read about our products and consider how they might benefit you or someone that you care about.
