Team 1: CozyAir Smart Vent System SUMMARY CozyAir is a smart vent system which addresses the problem of the rooms in a house or apartment being the same temperature. The CozyAir Smart Vent System consists of smart vents, a hub to which all vents are wirelessly connected and a smartphone app, which serves as the interface between the user and the vents. The app allows the user to turn on/off the HVAC system and redirect air flow through the vents’ blades. Current existing smart vent systems were explored in our research to pinpoint key features that must be at the core of the product to maximize energy and monetary savings. After researching the commercial and technological viability of CozyAir, we concluded that there is a real opportunity to help thousands of homeowners to save energy and reduce their monthly energy bills.

Team 2:  Flexible Continuous Glucose Monitor SUMMARY Diabetes is a life-threatening disease with no cure and is diagnosed in nearly 30 million Americans, according to the American Diabetes Association. Management of glucose levels is imperative in staying healthy and is done using glucose monitoring devices that can be used manually, or that monitor levels continuously without intervention. FlexCom has been designed to be used by a diabetic patient to monitor their glucose levels continuously. It is a continuous glucose monitor designed with comfort and flexibility in mind. It can be used with rechargeable or replaceable batteries. We consider it important to allow the user to have the option of replacing just the battery as opposed to replacing the entire transmitter. The transmission of glucose readings is done using Bluetooth LTE, as the device allows for the storage of several hours of readings using flash storage.

Team 3:  B.A.T. (Blind Assistive Technology) SUMMARY According to the World Health Organization, approximately 285 million people in the world are visually impaired. Of those 285 million, 39 million are blind and 246 million have low vision. Currently, most blind people navigate through life with canes, human assistance and service dogs. While these solutions are adequate, we present a better option. We created a better solution to help the visually impaired navigate through their day-to-day activities by warning them of nearby obstacles/dangers using vibrations. The B.A.T. (Blind Assistive Technology) device is a wearable band that can be placed around the head, wrists, legs or even waist. This device is equipped with sensors to detect nearby objects. The vibration intensity correlates with distance and danger level to give users a general idea of their surroundings. B.A.T. allows the user to access various functions of the device by tapping on the band. We found it important to use current technology to help this large community and build upon existing modern solutions. The functions on this wearable band device will allow for ease of navigation for the visually impaired while not obstructing their hearing, one of the senses that is most relied on by those who are visually impaired.

Team 4:  F.R.S. (First Response Sleeve) SUMMARY The F.R.S. (First Response Sleeve) consists of a capacitive touch sensor that is capable of recognizing gestures made by the user. The sensor is incorporated into a sleeve that will show its output to an LCD screen. The purpose of the F.R.S. is to assist first responders. When a first responder arrives to a chaotic scene, it may be difficult to hear orders over the radio. This is where our product, the F.R.S., is used. Users only need to look at their forearm and the F.R.S. will show the required information and allow them to browse through the information with its capacitive touch sensors. This helps users make the right decisions in possible life-saving scenarios. Our product has a 2x2 capacitive sensor matrix, which has the capability of recognizing horizontal swipes and vertical swipes in any direction. The gesture commands are used to execute commands visible on the LCD. In our demonstration, the device receives data via Bluetooth to simulate a dispatch feed to the sleeve.

Team 6:  Wearable Alcohol Sensor SUMMARY The Wearable Alcohol Sensor tracks breath alcohol levels as needed. The results are wirelessly transmitted to the user’s personal computer or smartphone via Bluetooth. Our easy-to-use companion app makes the process a breeze. It works as follows: when the sensor is ready, the user blows into it and after a few minutes results are available. Our design has incorporated a high precision sensor that consumes a very small amount of power coupled with a battery that lasts all day. The wearable has been designed to comfortably fit around the wrist of the user.

Team 7:  Skyleep SUMMARY It is estimated that more than eight million people have suffered from an episode of sleep-walking in the United States alone. The consequences of sleepwalking are known to be as mild as walking around a bed to as dangerous as driving a car for long distances. This can cause terrible accidents and unintended injuries to a person suffering from this condition, and to others involved in the car crash. Our team has developed Skyleep, which detects any sleepwalking activity soon after it starts to awake the user and prevent damage and/or injuries to themselves or others. We use a camera and an SD card stores images when motion is detected. An MP3 shield and a Text 2 Speech circuit are used to provide alarms and voice instructions to the user.

Team 9:  Pet Portal SUMMARY Pet Portal is a smart pet door system which uses facial recognition and PIR sensors to detect a pet and give it permission to unlock the pet door. The sensors detect the presence of the pet and wirelessly transmit this information to the Pet Electronic Terminal System (P.E.T.S.), which is the host management system. P.E.T.S. allows the users of android devices to connect to it through a Bluetooth network. The Pet Portal includes a facial recognition system and a central terminal. We felt compelled to do this project because we were looking for a solution to give pets the freedom to be inside and outside of their home as they please. While addressing the major implications of home security, Pet Portal is a system that allows pet owners to grant access to their pet remotely or through a facial recognition system. Homeowners can now manage and monitor their pet entering and leaving the premises from anywhere and at any time.

Team 10: Autonomous Indoor Navigation System SUMMARY The Autonomous Real-Time Indoor Navigator (ARIN) addresses the tasks of supporting autonomous navigation and mapping in the ever-changing indoor environments and the lack of availability of satellite GPS signals inside buildings. Indoor environments are in a constant state of change. These dynamic indoor environments are prevalent in an ever-growing number of locations. A challenge is to maintain an accurate layout of indoor facilities to accommodate the use of devices, utilities and people that depend on precise layout configuration. We employ an autonomous robot that implements the Simultaneous Localization and Mapping algorithm (SLAM) incorporating image processing and data mining to accurately map the layout of indoor facilities. The main tasks accomplished through the project consist of designing a robot that can navigate and accurately record the layout of indoor locations and upload the layout details to a centralized database, which can be referenced for path planning tasks. The application of this technology will diminish the laborious and error prone job of mapping the constantly changing layout configurations, while making the system intuitive and simple to use.

Team 11:  Smart Soaker System SUMMARY The Smart Soaker System is a management tool for already existing auto-irrigation systems which help users have beautiful green lawns while also saving on water and money. The Smart Soaker System is a small device that consists of multiple moisture sensors that communicate with each other, a microcontroller and a user-friendly mobile application. The moisture sensor reads the moisture of the soil and communicates with the sprinkler controller to turn on or off the sprinklers. The microcontroller is used to signal to the sprinkler system to control the pump that distributes the water. The mobile application provides the user with information about their lawn’s watering schedule and gives them the power to remotely turn on the sprinklers. The Smart Soaker System benefits people who want to have greener lawns, protect the environment and save money on their water bill. Our product revolutionizes sprinkler systems making them IoT (Internet of Things) devices, allowing the user to freely control and turn on the system when the soil needs it.

Team 12:  Modular Electronics Lab (MEL) SUMMARY Students of all ages are struggling to learn and understand electronics. This is mainly due to the difficulty associated with finding affordable quality electronics equipment which can be used to test circuits and make the learning process easy. There are only two main types of products in the market. One type is the common all-in-one lab which connects to the computer, while the other type is designed for high precision measurements. Our project establishes a middle ground in the marketplace providing consumers with an affordable, yet high-quality electronics laboratory. The Modular Electronics Lab (MEL) consists of four modules: the Main Power Supply Module, Adjustable DC Power Supply Module, Function Generator Module and Oscilloscope Module. By being modular, the cost of the overall product is dramatically reduced and the lab is permitted to “grow” with the user.

Team 13:  Real Time Fill Level Sensor SUMMARY The Real Time Fill Level Sensor consists of a system of nodes with ultrasonic sensors that collect water and waste level information. The nodes are connected to a gateway that sends the collected data to an API. These devices are placed in special baskets located underground in sewers, with the objective of monitoring which baskets are in danger to be flooded. Each (node) is composed of an ultrasonic sensor to measure the fill level of the baskets, a Raspberry Pi to process the collected data and a LoRa antenna to send the data to the gateway. This project enables local government to react with enough time to prevent material damage and for individual users to avoid commuting on streets flooded or in danger of being flooded.

Team 14: PEGASUS Satellite Communication System SUMMARY The PEGASUS Satellite Communication System provides high-speed data transfer for CubeSAT satellite communication systems. We have designed, assembled and tested a satellite payload and ground station capable of transmitting and receiving data across long distances. Utilizing high speed NI USRP transceivers, NI LabVIEW communication software, low-cost handmade antenna and custom-built amplifier systems, this communication system transmits and receives textbased sensor data and images from the satellite payload. Our team has developed programs in LabVIEW, Python and Arduino, and has built power and amplifier circuits to ensure the continuous operation of the satellite for the lifespan of its space mission. PEGASUS can also be used to perform tests of various CubeSAT and nano-satellite payloads on high altitude balloon. This system helps promote the study of space communications by providing a reliable and effective communication system for universities and researchers.

Team 15:  Multi-Sense SUMMARY Repeatedly, we see news of children, babies and animals dying inside parked cars. It is a reality in our modern society, where cars contain advanced computers and safety systems installed like anti-lock braking and lane departure warning, but have a lack of technology dedicated to protecting vulnerable life when a vehicle is turned off. Individual components exist in the market that can work in unison to provide critical information to the right people. The Multi-Sense System can be easily deployed to any vehicle, accurately detect a living being inside the car, report to the appropriate parties and potentially save the life of an occupant left behind. It completes these tasks using an array of sensors integrated seamlessly into a single package.

Team 16:  Autonomous Grout Cleaner SUMMARY The Autonomous Grout Cleaner is a fully autonomous machine that efficiently cleans grout lines with minimum or no human input to eliminate any hectic physical work. This product is a necessity for homeowners that have tile flooring. The grouts between tiles turn from white to a darker not so clean color. This has been a pain for homeowners when having to keep those lines in between the tiles clean. The Autonomous Grout Cleaner is composed of sensors for obstacle avoidance, grout line detection and self-navigation. We used standard IR Sensors for obstacle detection and an IR Reflective Sensor for the grout line detection. The cleaner includes a liquid dispenser which dispenses the cleaning chemicals to rub off the dirt of the grout lines and applies a layer of protective liquid directly on the grout line to reduce the grout getting dirty in the future. Once the device is fully running, it will follow the grout line on straight path and will clean the grout line as it continues to proceed. If the device for some reason loses alignment, the Reflective IR Sensor will allow for the straight forward path for the device. Once the sensors sense the intersection of the grout lines, the chassis will come to a stop and all other components will also stop as a result.

Team 17:  Bioz SUMMARY Bioz is a non-invasive external bio-impedance measuring device that gathers information of the internal qualities of organisms such as plants and their fruits; humans, and animals. The device works by supplying a small AC current to the subject and calculating the impedance due to the voltage drop measured between the two inner probes of the sensor we designed. For this project we used standard electronics materials such as resistors, capacitors, operational amplifiers, an LPC1768 micro controller, as well as sliver for the sensor we created. Bioz provides insight into the different chemical and biological states of organisms, their internal quality in the case of fruits, hydration in the case of humans, etc., through a simple non-invasive impedance test.

Team 18:  Wearable, Autonomous Robotic Legs SUMMARY The Wearable, Autonomous Robotic Legs provides people that are not able to use their legs with an option, more empowering than a wheelchair, to get around and carry out their day to day lives. The exoskeleton is controlled by a neural network based on the NeuroEvolution of Augmenting Topologies (NEAT) algorithm. This network would allow for the system to tailor itself around the user. This project has a very positive benefit in society as it allows for people that are disabled to reclaim the independence they once had. The entire project is programmed using C for the hardware and C++ for the neural network. Our hardware consists of two raspberry pi 3, 3 gyro-mag-accel, two infrared sensors and six electric linear actuators. We used programs like valgrind for memory leaks, dbg as our Linux debugger and mpi to run on the raspberry pi cluster’s multiple cores.

Team 20:  VR/Armor SUMMARY VR/Armor aims at creating a universally accepted motion control technology that can be used in the fields of video games, modelling, virtual reality, video conferences, as well as other immersive experiences. Our system primarily relies on a Bluetooth 4.0 architecture to relay the information from the wireless peripheral to the host computer via the on-board Bluetooth 4.0 functionality or through an optionally provided dongle. VR/Armor aims to put more power in the hands of the consumer by bringing back choice when shopping for peripherals used for motion control system, virtual reality environments, as well as other systems which require immersion, and real-time tracking. One of the major points of VR/Armor is that you do not need to be in the same room as the positioning equipment leading to a plethora of choices when it comes to creating your own setups.
