Polytechnic University of Puerto Rico is supporting and encouraging the submission of patent applications from faculty and staff, according to the current Intellectual Property Policy approved on February 24th, 2010. This effort is done to incentivize the production of intellectual property that benefits both, the IP originators and the university. The following steps will be followed to submit an application for patent:
1. The applicant will fill an Intellectual Property Disclosure Form and submit it to the Sponsored Research Office (SRO).
2. The SRO will hire a firm to conduct a Patent Search, and will determine if the Intellectual Property (IP) is considered a University Assisted or Assigned Effort or an Individual Effort. Based on the outcomes of the patent search, the SRO will submit a recommendation to the Intellectual Property Committee (IPC).
3. The IPC decides if the University will pursue a patent for the submitted IP.
4. If the University IPC decides to pursue the patent,
– The applicant will fill out an Originator Assignment Document
– The SRO will hire a firm to conduct a patent application. The applicant will meet with the firm personnel for any further explanation necessary in the generation of the claims for the patent application.
5. Once the patent pending status is documented, the University may initiates negotiations for the commercialization of the Intellectual Property.
6. If the University decides not to pursue the patent, the applicant may request a copy of the IP decision to pursue the patent of the IP on his/her own.
Highly-interactive, graphically-oriented, special purpose Finite Element Analysis program, within MS-Windows environment as the Graphical User Interface (GUI). The system has been developed for PC computers, and Visual Basic has been selected as the programming language, due to its versatility and the advantages of its toolbox to develop applications following the MS-Windows standards.
The application is called NPB program, which can be defined as an interactive computer program for the analysis of Non-Prismatic Beams (or similar structures) by means of plane stress Finite Element Analysis (FEA). The program performs plane stress analysis, using four nodes isoparametric elements (Q4), considering static loads, linear elastic material behavior, and the small displacements theory. It is specifically oriented to non-prismatic beam type models (defined by two vertical boundaries at the most left and the most right limits).
A model analysis may be divided into three implementation phases: a) Pre-processing Stage, where the model data is defined, b) Processing Stage, where the automatic meshing of the model, and the finite element analysis are performed, and c) Post- Processing Stage, where results are consulted. Regarding these phases, the program permits the user, among other features, to:
Define the parameters to control the number of divisions for the meshing II.2Perform the automatic meshing of the solid modeling with quadrilateral elements Perform an static linear elastic analysis of the model, using plane stress elements.
Review the results file (nodal displacements, element strains and stresses) Future developments will include the graphical post-processing of the results (i.e. deflected shape, stress contours, etc.)

Highly-interactive, graphically-oriented, special purpose Finite Element Analysis program, within MS-Windows environment as the Graphical User Interface (GUI). The system has been developed for PC computers, and Visual Basic has been selected as the programming language, due to its versatility and the advantages of its toolbox to develop applications following the MS-Windows standards.
The application is called Visual Slab program, which can be defined as an interactive computer program for the analysis of slabs on grade models, subjected to moving truck loads, and falling weights. The program speed up model generation, performs the automatic meshing (Finite Element Model) of the solid model, and performs static and dynamic (time history) analysis using isoparametric four nodes plate elements, dowels connecting plates, considering non-linear soil behavior, and the small displacements theory.
A model analysis may be divided into three implementation phases: a) Pre-processing Stage, where the model data is defined, b) Processing Stage, where the automatic meshing of the model, and the finite element analysis are performed, and c) Post- Processing Stage, where results are consulted. Figure 5 schematizes this processes, and Figures 6 to 8 show examples of the program capabilities.

The UPR / PUPR / ATI Professional Development Program, in operation since the summer of 2004, integrates students and faculty from eight disciplines, three campuses, and two universities: the Mayagüez and Río Piedras Campuses of the University of Puerto Rico and the Polytechnic University of Puerto Rico (PUPR) through the Puerto Rico Highway and Transportation Authority (PRHTA) and the Integrated Transportation Alternative (ATI).
The development program is based on four focal principles: real learning experience, multi-disciplinary approach, applied-research, and leadership development.
The primary objective of the program is to develop local professionals and leaders that are able to plan, design, build, operate, and maintain public transportation systems. The secondary objectives are to:
1. strengthen the education and research in key transportation infrastructure-related disciplines,2. establish a interdisciplinary cooperative model between engineering, architecture, urban planning, business administration, and social sciences professionals working alongside with government and industry officials, and
3. develop a cooperative relationship among the campuses of UPR Mayagüez, UPR Rio Piedras, the Puerto Rico Polytechnic University, the ATI, PRHTA and the PR-DTOP.
The UPR/PUPR/ATI Professional Development Program exposes students to the SJMA complex transportation environment through an applied research experience that has the following three stages:

The Professional Development Program In Transportation Infrastructure Inspection (PDP-TII) is a cooperative agreement between Alternate Concepts Inc (ACI) and Polytechnic University of Puerto Rico (PUPR).
The Program has three principal objectives: – Stimulate the development of engineering students in the area of Transportation Infrastructure Inspection and Maintenance. – Perform an inspection and maintenance assessment program of the San Juan Railway System (TU) structures and drainage infrastructure. – Propose possible improvements to the inspection, condition evaluation, and maintenance assessment processes of transportation facilities. The program consists of five stages:Students have to perform extensive literature review on visual inspection procedures and condition assessment rating around the world, and propose improvements in all the stages of the process:
– Inspection procedures and equipment. – Inspection forms. – Infrastructure identification and location. – Findings documentations. – Assessment of the field conditions found trough objective and quantitative rating scales.– Required level of intervention according to obtained rating (i.e. routine maintenance, repair, replacement, among others),to support the establishment of priorities in the maintenance process.
The concepts learned in the previous stage are applied to different components of the TU infrastructure.
Example of Damage Found in Sidewalk Parapet
The findings of the inspection are evaluated, and a condition rating is assigned (that helps decide the type of maintenance process required to assure adequate safety and operational conditions).
A detailed report of the findings and the assigned condition is developed. An evaluation of possible causes to the discovered findings, and recommended intervention are also developed.
