Work Experience 

Ruth Consulting LLC, 2007-present

Analyze performance of automotive restraint systems in crashes.  

Read automotive Event Data Recorders (EDR’s) using the Bosch Crash Data Retrieval (CDR) system.  Also read vehicles not covered by Bosch CDR using the specialty GIT Hyundai & Kia EDR kits, the Subaru SSM3/SSM4 software w/Denso interface, the Mitsubishi EDR tool and the Tesla tool. Apply the data to Traffic Crash Reconstruction to determine vehicle speeds and driver behavior prior to impact.  Assist engineers and lawyers in understanding how to make the best use of EDR data in their cases.  Assist prosecutors and other attorneys in EDR data admissibility hearings. Assist crash reconstructionists and attorneys in getting EDR data from manufacturers not covered by any publicly available tool. 

Instruct police officers and accident reconstructionists in reading and interpreting EDR’s as contractor to UNF-IPTM, SAE, and custom instruction through Ruth Consulting.  

Conduct EDR accuracy research and publish findings in peer reviewed professional journals to pave the way for improved data admissibility.

Speak at national and regional accident reconstruction conferences on new developments in EDR’s.  

Perform beta testing for the Bosch Crash Data Retrieval system.  Assist automobile manufacturers in improving new releases to Bosch CDR.  

Consult on accident reconstruction and analysis including human factors, restraint systems performance in crashes, and occupant kinematics. 

Read and interpret HVEDR data using the Synercon Forensic Link Adapter with Synercon and truck engine manufacturer software.

Read and interpret in-vehicle navigation and infotainment (phone/text) information using Berla iVe hardware and software.
