Amusement Rides
Performed extensive work with various amusement rides and devices including working with powered zip lines, drop rides, pendulum swing rides, and slingshot rides. Conducted comprehensive analysis for compliance with ASTM standards, and structural analysis for static and fatigue loading conditions including preparation of full calculations packages and reports. Analytical work for structural analysis of amusement rides included finite element analysis modeling, hand calculations, fatigue analysis of structures including welded structures, and dynamic and kinematic analysis. Also performed physical testing of amusement rides, including accelerometer testing.
Exercise Equipment
Extensive work with exercise equipment including weight machines, electromechanical exercise machines in various form factors, exercise assistance products and semi-automated massage equipment. Designed multiple pieces of exercise equipment from the ground up and performed analysis to assure compliance with applicable ASTM standards including structural calculations. Structural analysis work included comprehensive calculations packages based on finite element analysis, hand calculations, and fatigue analysis. Experience with prototyping.
Heavy Hydraulic Equipment and Lifts
Experience designing and operating heavy equipment including aerial lifts. Experience in accident reconstruction involving MEWPs of various form factors,
counterbalance forklifts, telehandlers/rough terrain forklifts, bulldozers, automated refuse trucks, and tow trucks. Work included hazard analysis, foreseeable misuse analysis, and considerations of safer alternative designs. Performed physical cycle and fatigue testing for lift controls and energy chains. Experience reading and analyzing crane black box data.
Drill Rigs and Mining
Designed, reverse engineered, and tested drill pipe wrenches and clamps as well as heavy mining equipment including simulation rooms, centrifuge mounts, drill rig structures, and more. Experience in accident reconstruction involving drill pipe handling and storage.
Trailers
Designed trailers in multiple form factors including beer dispensary trailers, multicart carrying trailers, and pneumatic trailers. Selected towing hitches and
testing hitches. Testing was done in accordance with SAE standards.
Electronics and Firmware
Designed, built, and used/tested numerous special-purpose passive and active electronic circuits including for aerial lift controls, fiber optic controls, electrohydraulic valve controls, repeatability and timing circuits, biological testing systems, fatigue cycle testing, and motor control. Designed and built many instrumentation circuits including for strain gauges, anemometers, optical measurement, proximity sensors, capacitive sensors for fluid detection, thermocouples and RTDs, and more. Done work in battery life testing, automation of common daily tasks using servo controls, detonation circuitry, and PWM control of LEDs, solenoids, Peltier modules, and more. Work also included circuit design, calculations, microcontroller firmware development and deployment, prototyping, thermal and noise stabilization, and analog and digital signal processing.
Consumer Products
Designed and/or analyzed various consumer products including consumer grade printing presses, racing seat simulation bases, basketball standards, electric lawnmowers, refuse receptacles, trampoline frames, urinal screens, construction hardware, and blenders/blender jars. Work included reverse engineering and redesign, motor testing, instrumentation, data collection/processing, statistical analysis, prototyping, structural calculations and simulation.
