Lab Equipment

The Srivastava Senior Design Lab has a wide selection of equipment that provides nearly all of the capabilities of the other ECE teaching labs in one place. Although the equipment may not be identical to that found in these other teaching labs, similar functionality is offered. Use the experience of learning new equipment as a way to expand your horizons. If you are using a piece of equipment for the first time, ask a TA for assistance, to make sure you understand how to safely use it. If the available equipment does not meet the needs of your project, talk to the course staff, and we will help you find what you need elsewhere on campus, consider purchasing it for the senior design lab (if it would be used by many groups), or brainstorm alternate ways to solve your problem.

Lab Kits

Each team is provided with at least one lockable storage drawer in the lab as well as a portable lab kit. An additional drawer and/or kit may be issued as need arises and facilities allow.

The lab kit includes a box with carrying handle and contains a wiring board for prototyping circuit projects, a multiple-output power supply, a digital multimeter, and a set of 8 cables (2 bnc/bnc, 2bnc/pin, 2 banana/banana, and 2 banana/pin). This is checked out to you by your TA at the beginning of the semester and must be returned undamaged at the end of the semester. Missing lab kits will result in an encumbrance or withheld diploma and a charge of $500.00, so always be sure to lock your lockers! Also, do not store any cables from the lab in your kit. Doing so will result in a loss of points.

Test Equipment

Most equipment is connected to the PCs via HPIB cables. Below is a sampling of the test equipment available:

Specific setups at the various lab benches can be in the listing at the bottom of this page.

Computers

The lab has PCs with enough processing power for the needs of nearly any senior design project. These machines are networked to a high-capacity laser printer (printing will count against your standard print quota). Each has an Ethernet connection to the campus network, an HPIB interface card connecting it to all of the standard instruments on its bench, and a sound card. The computers are maintained by Engineering IT, located in 3080 ECE Building.

The PCs are presently configured with the software shown here. Their primary uses include:

Digitizing the Restaurant with Network-Enabled Smart Tables

# Problem:

The restaurant industry relies on relatively archaic methods of management and customer service. Internal restaurant computer systems are limited and rely on staff members to monitor customer status. Restaurants lack contact-free transactions for clientele.

# Solution Overview:

Our solution to this problem is to develop a standalone LAN restaurant network system to manage customer status and occupancy for restaurants without the need for personnel to monitor it manually. Along with this, to accommodate for contact-free interactions, we propose a system for payment methods. To address customer preferences, we will provide height accommodation built into the table for different types of people.

# Solution Components:

[Self-adjusting Customer Height Accommodation] - The table will be held up with a linear actuator, thus allowing for the overall height to be adjustable. The table will adjust its height accordingly to the customers’ heights once they sit down. We plan to make the table adjust the table’s height by measuring the distance between the bottom of the table with the customer’s knees when they are sitting down using ultrasonic sensors.

[NFC Payment and Card Reader Payment] - The table will have NFC reader and magstripe reader for contactless delivery. The payment data will be sent to the centralized hub for processing and confirmation.

[Table Pressure Sensor] - The status of a table will be gauged based on the amount of weight on the physical table itself. An occupied (or even just an unoccupied and dirty table) will be marked as such since the weight of excess food, water, plates, and whatever else the customer may bring will be measured by this pressure sensor.

[Computer Mesh Network] - We plan to create a mesh network of raspberry pi’s to track the status of tables in a restaurant. This network will communicate via some form of wireless communication (Wi-FI, bluetooth, or Zigbee).

# Criterion for Success:

This project seeks to create a solution in which restaurants can minimize customer interaction with features that accommodate individual needs, such as the height of the table and payment methods. This project will be considered successful with a working prototype that includes features that may be included in an actual restaurant setting.
