# Problem:

Restaurants commonly struggle with expensive POS and reservation systems. Now, more than ever, restaurants are looking to cut costs and manage space in order to keep their doors open. Also, there is a growing concern for health and safety which hinders the efficiency of the restaurant and intimidates potential customers.

# Solution Overview:

Our solution to this ongoing problem is to create a comprehensive system to manage reservations and POS. By utilizing Computer Vision and historical data, we can provide customers with accurate and adaptive predictions for their wait time. The customer can reserve their table through a mobile application and, once seated, may order and pay through the application as well. The client [restaurant] will receive these orders from a client-facing side of the application.

# Solution Components:

[Application] - Building a POS for the restaurant by building a mobile/web application that will allow users to view the menu, order from the menu, and pay using their phones. Additionally, this application will display which tables are occupied, which tables are about to be available and which tables are available.

[RFID Scanner] - Using an RFID scanner, the servers/bussers can scan an RFID tag on each table once the table has been cleaned and is available for another customer. This will be an accurate way to indicate when a table is free.

[Computer Vision] - We will use computer vision to determine if a table is occupied or if it is empty. We will train a model on a dataset that we receive from restaurants and will be able to be used in conjunction with the RFID and the POS application to determine if the status of a table. Additionally, historical data will assist in determining accurate waiting times.

[Thermal Sensor] - We will use a thermal sensor in combination with a camera to determine whether or not a particular table is occupied. This should provide more than enough assurance that the table is, in fact, occupied. Furthermore, this component will allow for some more complex processing to be performed on our PCB.

# Criterion for Success:

On a high level the goal of this project is to aid restaurants through this pandemic by reducing the amount of interaction between servers and customers. We hope to achieve an efficient and effective solution that increases a restaurant's revenue and improves the customers experience.

The goal of this project is to design a low cost BMS (Battery Management System) system that is flexible and modular. The BMS must ensure safe operation of lithium ion batteries by protecting the batteries from: Over temperature, overcharge, overdischarge, and overcurrent all at the cell level. Additionally, the should provide cell balancing to maintain overall pack capacity. Last a BMS should be track SOC(state of charge) and SOH (state of health) of the overall pack.

To meet these goals, we plan to integrate a MCU into each module that will handle measurements and report to the module below it. This allows for reconfiguration of battery’s, module replacements. Currently major companies that offer stackable BMSs don’t offer single cell modularity, require software adjustments and require sense wires to be ran back to the centralized IC. Our proposed solution will be able to remain in the same price range as other centralized solutions by utilizing mass produced general purpose microcontrollers and opto-isolators. This project carries a mix of hardware and software challenges. The software side will consist of communication protocol design, interrupt/sleep cycles, and power management. Hardware will consist of communication level shifting, MCU selection, battery voltage and current monitoring circuits, DC/DC converter all with low power draws and cost.
