CSU–Pueblo engineering faculty earn patents and award for their research efforts


Colorado State University-Pueblo engineering professors have earned patents from the United States Patent and Trademark Office in the last few months along with a separate award for best research paper in a regional competition.

Dr. Nebojsa Jaksic was granted a patent in April titled “Method for Manipulating Objects,” a device that moves various objects by using air. This is thought to be the first patent granted to a CSU-Pueblo faculty for work done on the CSU-Pueblo campus.

Jaksic was granted a patent for a simple and inexpensive method and apparatus that manipulates both irregularly sized and porous objects by using air by creating a low pressure zone between a plate with a gas-flowing surface. Gas flow is used to create an attraction force between the apparatus and the object to be manipulated. The low-pressure zone created between the surface and the object results in a force acting on the object and towards the plate. By moving the plate, the object is moved.

The method and apparatus are easy to implement and provide contact manipulation of objects. Jaksic said after an extensive search of patents and relevant literature in engineering journals and books, he could not find anything applicable to contact object manipulation by employing low-pressure zones created by pressurized gas flow.

Dr. Jude DePalma, along with Todd Schlegel (Nassau Bay, TX), and Saeed Moradi (Houston, TX) earned a continuation patent for their real-time, high frequency QRS electrocardiograph with reduced amplitude zone detection that was produced in conjunction with research conducted through the National Aeronautics and Space Administration.

Real time cardiac electrical data are received from a patient, manipulated to determine various useful aspects of the ECG signal, and displayed in real time in a useful form on a computer screen or monitor. The monitor displays the high frequency data from the QRS complex. The high frequency data are analyzed for their root mean square (RMS) voltage values and the discrete RMS values and related parameters are displayed in real time. The high frequency data from the QRS complex are analyzed with imbedded algorithms to determine the presence or absence of reduced amplitude zones, referred to as "RAZs". The RAZ and RMS values are parameters that are more sensitive than conventional ECG parameters in detecting the presence of myocardial ischemia and infarction.

A conference paper by two CSU-Pueblo engineering faculty members and an engineering graduate student, “Lander Design Project for Autonomous Rovers,” by Jaksic, Hüseyin Sarper, and Senay T. Imam, won the Best Paper Award at the annual American Society for Engineering Education (ASEE) Rocky Mountain Section Conference held in April at Utah Valley University, Orem, UT. The Rocky Mountain Section of ASEE includes four states: Colorado, Utah, South Dakota, and Wyoming.

The goal of the project reported in this paper was to create an autonomous lander with a parachute. The lander was designed to land on its base while absorbing much of the impact during landing and to carry an autonomous rover up to a size of 11”x 8”x 9”. The lander contained sensors, an antenna, and a microcontroller board programmed to regulate each stage of the flight. The design, building, testing, and demonstration tasks were extremely beneficial to educational development of students because they had to learn many new concepts quickly and work in a team environment. Each student worked on a different aspect of the lander.
