Kender Technologies, Inc was formed in 2008 to provide Accident Reconstruction and related services. The founder, Daniel Kender, MS served as Police Officer from 1993 to 2021. He became a Crime Scene Investigator in 1995, a traffic crash investigor in 1997, and an Accident Reconstructionist in 1999. Meanwhile, Daniel Kender completed a bachelors degree in computer information systems and a masters degree in digital forensics and cyber security. As such, Kender Technologies specializes in the growing intersection between traditional accident reconstruction and digital technology.

Forensic investigations often require that investigators document the precise locations of physical evidence. Kender Technologies uses an accurate prismless total station to quickly and accurately document the physical evidence and static features of a scene. Once the measurements are complete, data from the total station is transferred to a forensic CAD (drawing) program for further analysis.

Another method for accurately locating evidence at a scene is through the use of photogrammetry. Photogrammetry places items of physical evidence at a scene by locating them relative to static scene features that appear in scene photographs. Kender Technologies uses a forensic photogrammetry software program to quickly and accurately place items of physical evidence at a scene using scene photographs. Photogrammetry is useful when there are photographs of physical evidence and the physical evidence no longer exists at the scene.

Kender Technologies is offering automobile “black box” downloads*. These downloads may contain up to five seconds of pre-crash data such as

• Vehicle Speed
• Percent of Throttle
• Brake Usage
• Steering Input
• Seatbelt Usage

It may also contain other crash data such as delta-V (change in velocity during collision), which could indicate the potential for injuries and can be used to determine the speeds of other vehicles involved in the crash.

Not every personal injury case involving a motor vehicle warrants the expense of a full accident reconstruction. However, the data from an inexpensive “black box” download may provide invaluable evidence for use in litigation**. Kender Technologies uses the same Bosch Crash Data Retrieval tool that is used by other companies that are charging more than $400 for a download. Why spend more money to get the exact same data? For more information or to schedule a download contact Kender Technologies at 219-310-4178.

*Only for vehicles supported by the Bosch Crash Data Retrieval CAN Plus tool. Mileage charges may apply for travel outside of northwest Indiana or Northeast Illinois.
**The downloaded data may require an analysis by an Accident Reconstructionist to be admissible in court. This service is also available for an additional fee.

With the ever-growing use of cell phone cameras and surveillance video, video forensic analysis is often the best solution for determining vehicle speeds. The process involves splitting the evidentiary video into individual frames, determining the frame rate, and measuring the real-world location of fixed objects that are visible in the video. This data is then used to determine the speed of the vehicle between the fixed objects.

It is often difficult for a forensic expert to convey complex concepts to a jury of non-experts. If a picture is worth a thousand words, then imagine how much a video is worth. Kender Technologies uses a video game engine to create interactive forensic animations that are both realistic and accurate. Viewers can toggle through several camera angles to include what drivers and witnesses likely saw before and after the incident. Playback speed can be slowed or even paused during play. The animation writes the data to a text file for analysis by apposing experts. Since the animation is designed in computer code, it's possible to include the results of different analysis and what-if scenarios.

It may be possible. But is it probable?

There are often uncertainties involved in accident reconstruction cases. Parameters such roadway friction values, perception-reaction times, and vehicle acceleration rates are just a few. Some private Accident Reconstructionists will simply guess, often choosing the parameters that best suit their client. Their results are easily challenged by a knowledgeable apposing expert.

By contrast, a Monte Carlo simulation is a computerized mathematical technique that generates random numbers for each of the unknown parameters based on the statistical probability of each. The simulation will repeat numerous times using a different set of random numbers each time. When the Monte Carlo Simulation is complete, it yields a range of possible outcomes with the probability of each result occurring.
