President – Klover Products was incorporated jointly with an Innalytical Solutions customer to produce unique products for the television broadcast industry.

Our first product was the parabolic microphone designed at the request of Fox Sports.  We have expanded that product line to three different sizes.  These parabolic microphones have been used to broadcast the Super Bowl, World Series, MLB All-Star game, NBA All-Star game, and the NCAA men’s basketball tournament.  Klover Products’ second product line is a system of removing moisture and debris from video camera lenses.

2014 – Created the “Sound Shark Audio” division to expand the parabolic microphone products into the consumer market.

January 2004 to Present – Innalytical Solutions Inc.

President – Providing engineering consulting services to a wide variety of customers including acting as expert witness in legal matters.

2009 to 2018:  Operated the “Machine Doctors” division to focus on the machinery service area such as troubleshooting, upgrades, and retrofits.

2011 to 2016: Operated the “Investigative Engineers of Southern Wisconsin” division to focus on forensic engineering services.

Significant projects include:

•Finite Element Analysis of service structures for nuclear reactors

•3D solid modeling, Finite Element Analysis, and created animated demonstration video for a sea floor oil shut-off valve

•Mechanical design of a spacer transport system and gas fill station for an automated assembly system of glass units (dual pane residential window panels)

•Mechanical design of a series of assembly cart for LEAN assembly of tractor axles

•Design of parabolic microphone that began Klover Products

•Mechanical design of test stand for scanner sensor for GE Medical

•Mechanical and electrical design, programming, and project management of a tire assembly system for off highway construction equipment

•Mechanical design, electrical design and programming of two gas strut assembly systems for off highway dump trucks

•Mechanical and electrical design of an autonomous servo driven mobile television stage – the lift arms from this design were used to lift the roof of the broadcast stage for Super Bowl 47 pre-game, half time, and post game shows

•Finite Element Analysis of the roof and roof rack for an automobile mounted sensor used for laser driven terrain measurements

•Mechanical design of robotic assembly and packaging system for injection molded plastic parts for second tier supplier to the automotive industry

•Replaced the entire CNC control system of two custom built punch press / plasma cutters – larger one capable of stamping and cutting ½” x 4’ x 10’ plate
