Forensic Engineering Experts: Airbags

By: Dr. Irving Ojalvo

Airbags are credited with reducing numerous injuries and saving many lives during vehicle accidents. However, there have been incidents where they do not function as intended, and have even caused injuries such as explosive powder burns, detached eye retinas, child suffocation and impact deaths.

Forensic Engineering Experts: Animation

By: Dr. Irving Ojalvo

Animations are useful visual tools that can help jurors understand how an incident could, or could not, have occurred. Simply describing an event in court, or showing still pictures, may be insufficient to explain a complex sequence of events.

Forensic Engineering Experts: Biomechanics

By: Dr. Irving Ojalvo

Biomechanics is the application of mechanics to the interaction of biological systems with their external environment. When investigating an accident, biomechanical analysis can be used to reconstruct a victim’s motion and relate it to his injuries.

Forensic Engineering Experts: Golf Carts

By: Dr. Irving Ojalvo

There are roughly 9,000 golf cart related accidents requiring emergency room treatment in the United States each year. The majority of these accidents are related to either braking, cart rollover or passenger ejection. These problems are common to golf carts due to their open design, lack of seatbelts, poor braking capabilities and the uneven terrains they are driven on.

Forensic Engineering Experts: Machine Guarding

By: Dr. Irving Ojalvo

The primary function of all guarding is to prevent an operator or bystander from being injured by a potentially dangerous portion of a machine. Often the hazard involves moving parts with the potential to cut, crush or draw-in body parts, although barrier guards may also be necessary when electrical, thermal or chemical dangers are present.

Forensic Engineering Experts: Ladders

By: Dr. Irving Ojalvo

There are over 100,000 ladder accidents annually in the U.S. requiring hospital emergency room treatment. Although many of these result from user misuse, such as an improper extension ladder lean angle against a wall causing it to slip outward, use of a damaged ladder, or failing to lock a step ladder’s spreaders, many ladders fail due to design or manufacturing defects.

Forensic Engineering Experts: Occupant Injuries

By: Dr. Irving Ojalvo

In many vehicle accident investigations, it is necessary to know not only the speeds and motions of the vehicles involved, but the causes of injuries suffered by their occupants as well. Such investigations seek to answer questions regarding occupant ejection, effects of seatbelt use, airbag deployment and body-interior impacts.

Forensic Engineering Experts: Parking Lots & Garages

By: Dr. Irving Ojalvo

Parking lots are the scene of many pedestrian accidents because of the close proximity of people and cars and the confusing traffic patterns that sometimes exist. In addition to pedestrian-vehicle collisions, many trip and fall accidents occur in parking lots as well.

Forensic Engineering Experts: Vehicle Rollover

By: Dr. Irving Ojalvo

In many vehicle rollover investigations, it is necessary to know not only the speeds and motions of the vehicles involved, but the causes of injuries suffered by their occupants as well. Such investigations seek to answer questions regarding occupant ejection, effects of seatbelt use, roof crush and body-interior impacts.
