Multi-contrast imaging and digital refocusing on a mobile microscope with a domed LED array

We demonstrate the design and application of an add-on device for improving the diagnostic and research capabilities of CellScope--a low-cost, smartphone-based point-of-care microscope. We replace the single LED illumination of the original CellScope with a programmable domed LED array. By leveraging recent advances in computational illumination, this new device enables simultaneous multi-contrast imaging with brightfield, darkfield, and phase imaging modes. Further, we scan through illumination angles to capture lightfield datasets, which can be used to recover 3D intensity and phase images without any hardware changes. This digital refocusing procedure can be used for either 3D imaging or software-only focus correction, reducing the need for precise mechanical focusing during field experiments. All acquisition and processing is performed on the mobile phone and controlled through a smartphone application, making the computational microscope compact and portable. Using multiple samples and different objective magnifications, we demonstrate that the performance of our device is comparable to that of a commercial microscope. This unique device platform extends the field imaging capabilities of CellScope, opening up new clinical and research possibilities

A survey of new technology for cockpit application to 1990's transport aircraft simulators

Two problems were investigated: inter-equipment data transfer, both on board the aircraft and between air and ground; and crew equipment communication via the cockpit displays and controls. Inter-equipment data transfer is discussed in terms of data bus and data link requirements. Crew equipment communication is discussed regarding the availability of CRT display systems for use in research simulators to represent flat panel displays of the future, and of software controllable touch panels

FPGA-Based Real-Time SLAM

This project created a proof of concept SLAM sensor suite capable of remotely observing and mapping areas by combining real-time stereo camera imagery with distance measurements and localization data to generate a 3D depth map and 2D floorplan of its environment. The system used a Xilinx Zynq SoC containing an embedded ARM processor and FPGA fabric, and implemented unique SLAM processing functionality using both embedded software and parallelized custom logic

Research And Development Of Industrial Integrated Robotic Workcell And Robotrun Software For Academic Curriculum

Robotic automation is consuming the laborious tasks performed by workers all over industry. The increasing demand for trained robotic engineers to implement and maintain industrial robots has led to the development of various courses in academia. Michigan Tech is a FANUC Authorized Certified Education Training Center for industrial robot training. This report discusses the research and development of an integrated robotic workcell consisting of three Fanuc robots, Allen Bradley programmable logic controller (PLC), Mini-Mover belt conveyor and Fanuc iR-vision system. The workcell allows students to explore an environment similar to industry and intended to be used for laboratory hands-on activities in two robotic courses: Real-time Robotic Systems and Industrial Robotic Vision System. To complement hands-on activities and to meet the need of educating robotics to those without access to physical robots, an open source robotic simulation software RobotRun has been created in collaboration with a faculty member and students from Computer Science department. The features and a few training examples on the software have also been presented

Design of A Virtual Laboratory for Automation Control

In the past, only students who studied on campus were able to access laboratory equipment in traditional lab courses; distance learning students, enrolled in online courses, were at a disadvantage for they could learn basic lab experiment principles but could never experience hands-on learning. Modeling and simulation can be a powerful tool for generating virtual laboratories for distance learning students. This thesis describes the design and development of a virtual laboratory for automation control using mechanical, electrical, and pneumatic components for an automation and control course at Old Dominion University. This virtual laboratory application was implemented for two platforms — Windows personal computers and Android smartphones. The virtual lab serves as pre-lab session for on-campus students and a virtual lab tool for distance-learning students to gain some “hands-on” lab experience. Utilizing the virtual learning environment as a supplement to engineering-based laboratories is also beneficial for students to prepare for the physical experiment and obtain a “hands-on,” practical lab experience without the hazards present in the physical lab. Such a methodology can also be applied to experiments in different fields such chemistry, etc

Inverted Fluorescence Microscope

Team F13 is composed of Trevor Blythe, Spencer Hann, Matthew Pfeiffer, and Thomas Eggenberger. We are all majoring in mechanical engineering and in our final year of study here at Cal Poly San Luis Obispo. This project is a continuation of a 2019-2020 senior project. The previous team designed and built a functioning inverted fluorescence microscope (IFM) from scratch. This device was created as a lab tool for undergraduate students to be able to perform experiments on microfluidic devices constructed in Cal Poly’s Microfabrication Laboratory. Although substantially functional, several design constraints had not yet been met. Our team has improved microscope robustness and functionality for practical undergraduate lab use. To do this, we set overarching goals including decreasing microscope footprint, increasing the accuracy of microscope positional repeatability, and improving user-friendliness. Within this Final Design Review report, the full design, manufacturing, and testing processes of this project are explicitly detailed, as well as project logistics, future suggestions, and project management

CREATING TOUCHPANEL GRAPHICS FOR CONTROL SYSTEMS

More often than system designers would like to admit, a discrepancy lies between the implementation of audiovisual control systems and their apparent ease of use to a novice or casual user. System designers and programmers are often hampered by the software tools provided by industry manufacturers and cannot reliably create desirable graphical interfaces that match the level of systems they are asked to program and install. Popular consumer trends in portable touchscreen devices, pioneered on devices such as the Apple iPhone, light a way forward into a new era of elegantly solving the audiovisual control system graphical user interface problem. Since expensive specialized hardware can be replaced by readily available consumer devices and a wide variety of tools exists with which to create content, possible alternatives to the current methods of designing the graphical user interface for the audiovisual system are ripe for discovery. Using the latest release of Autodesk Maya 2011, with features such as Python and Pymel, we have developed scripts to generate graphical user interface content for use with audiovisual control systems hardware. Also explored is the potential for a standalone development environment such that audiovisual designers and programmers are not required to operate Maya or adjust scripts to generate content. Given this new level of control over the graphical user interface, coupled with the flexibility of the control system central processor programming, a truly powerful, intuitive, and groundbreaking control interface can finally be realized

Autonomous Pedestrian Detection in Transit Buses

This project created a proof of concept for an automated pedestrian detection and avoidance system designed for transit buses. The system detects objects up to 12 meters away, calculates the distance from the system using a solid-state LIDAR, and determines if that object is human by passive infrared. This triggers a visual and sound warning. A Xilinx Zynq-SoC utilizing programmable logic and an ARM-based processing system drive data fusion, and an external power unit makes it configurable for transit-buses
