Dr. Amir Torabi Dr. Amir Torabi worked on hardware design methodologies to reduce power consumption of System-on-Chips (SoCs). Power management and estimation in complex SoCs and custom processors is of crucial importance to chip design companies and Semiconductor industry. These SoCs and processors are vital parts of embedded systems used in electronic equipments ranging from laptop computers, mobile phones to personal digital assistants. To reduce the power consumption in the final product, it is necessary to have an estimate of the power consumption early in the design process. It is becoming essential to utilize design methodologies to reduce and estimate power consumption at the high-level.

Jose Jose Martinez helped a team in developing embedded systems of the Internet of Things (IoT) devices. He has planned to focus on researching energy harvesting circuits consisting of converting different types of energies such as radio waves, heat, and vibration to electrical energy to power low energy devices such as sensors. Consideration of cost, performance, and efficiency in designing this circuit is at the upmost importance. An energy harvesting circuit that combines these sources to produce to most power was the goal.

Security and Surveillance Systems:

Energy Harvesting for Low-Power Wireless Devices:

Jordan Root Jordan Root worked on Energy Harvesting to convert ambient energy into electrical energy with the purpose of both storing the energy and powering devices wirelessly. With an increased focus on making technology connected to the internet, a concern is how environmentally friendly the technological advances are. A popular example is using photovoltaic cells to harness solar energy to store the power in rechargeable batteries or super capacitors to use the energy later and to reduce the environmental cost. Ambient energy can also come from other sources, such as electromagnetic and radio frequency waves, but at a lower power density. If technology advanced to where electromagnetic and RF waves were to produce more energy, then wireless charging of a phone would be more commonplace, and wires would become a thing of the past. The goal was to increase the power density of electromagnetic waves to power devices wirelessly.

Gerardo Gonzales Gerardo Gonzales worked on developing embedded system architectures of IoT devices used in health monitoring and surveillance. During the course of this work, he defined and captures the design of a system, and investigated the cost limitation, complexity, determines a system’s integrity, such as reliability and safety, works within the confines of available elemental functionality (i.e., processing power, memory, battery life, etc.) and marketability of such products. In short, he proposed an embedded systems architecture that can be used to resolve these challenges early in a project. A case study demonstrating his method followed at the end of the project.

Image Processing and Optical Character Recognition:

Daniel Madina Daniel Medina studied an Optical Character Recognition (OCR) algorithm aiming to improve the character recognition that is employed in many image processing applications. These improvements will help increase the continuing accuracy of OCR technology and find new ways with which to utilize OCR within a mobile application. OCR is essentially the segmentation of a pre-processed image file, followed by the feature extraction of the text within the image. Some popular products of OCR is Google Translate, PhotoMath, Adobe Acrobat, and Google Docs; allowing robust features like converting pdfs and images into text files as well as taking pictures of equation’s on your phone and using OCR to extract the text information so the application can solve the equations. The OCR within the applications hopes to improve on current screenshot picture accuracy with pictures taken in a dark lighting proving to be especially problematic. If OCR accuracy can be improved then many aspects of people’s lives can be made even easier such as on the fly translating of signs and billboards. Extracting text and using the information for specific everyday tasks to provide even more convenience to the everyday person was one of the main goals of his research.
