Developed a bicycle taillight called Survue which utilizes artificial intelligence to detect vehicles and warn the driver and cyclist of one another.

The design utilizes artificial intelligence to detect vehicles approaching from behind. If the vehicle is of risk to the cyclist an audio tone warns the cyclist. Simultaneously, the taillight pattern increases in intensity as the vehicle continues its hazardous path. If all warns fail and a collision occurs, the events leading up will be saved to memory for future usage.

• 6 hour battery life

• Detection range up to 130 meters

• 80 lumen light

Conceptualized a low cost CPAP machine to be used in developing countries for a nonprofit organization.

The concept utilized design for serviceability with multiple powering methods, including an automotive plug, solar, and a port to use common commercial AC adaptors. It included numerous automotive pressure, humidity, and temperature sensors that are more readily available in the remote region of the end user. The device had an onboard graphic user interface (GUI) and Bluetooth to smartphone interface for control.

Developed a joystick with tactile feedback to give heavy equipment operators indication that an electro hydraulic system had been activated.

A prototype was created and installed on a bulldozer at a job site. A user-centered evaluation led to subtle changes in design parameters. A second  iteration met the end user success criteria and the electronic schematic and hardware model was finalized for the customer.

Developed a natural gas sensor used to evaluate properties of natural gas.

The design excited the  gas and measured the reaction. The embedded algorithm then correlated the results to the content of the natural gas. A prototype was created consisting of an electronic circuit board, stainless steel housing, and a stainless steel sensor probe with the integrated transducer.
