Case Study: Wearable Scanner & Display Unit
Industry: Parcel sorting, re-routing and delivery
Customer: United States Postal Service (USPS) is the government agency responsible for postal services within the United States. With a vast network of post offices and processing facilities, USPS handles transporting, sorting, and delivery of letters and packages as well as options for domestic and international mail.
Challenge: USPS wanted a high-performance barcode scanner:
- Wearable form factor
- Displays sorting information
- Long battery life ~8 hours
- Extremely light but durable
- Right- or left-hand functionality
- Easy USB-C charging
- Meets durable IP54 specs
- Easy maintenance and repair
- No exposed wires to catch on objects
- Communicates with USPS’ proprietary global network
- Operates with Intelligent Mail® Barcode System
Solution:
The Wearable Scan & Display Unit (WSDU) is an extremely lightweight wrist-worn imager barcode scanner that communicates wirelessly with USPS’ proprietary server network.
Using a 3-axis gyroscope accelerometer, the trigger detects absence of movement before initiating the scan. Its algorithm minimizes false triggers for optimal performance and maximum battery life.
The WSDU has a display with buttons which enables the operator to view sorting information and status sub-menus as well as control the audible feedback volume of successful or failed scans.
The ergonomic design ensures efficient scanning and package processing. Weighing less than 150gm, WSDU offers comfortable, non-fatiguing usage over an extended time period. It accommodates right- or left-handedness and the adjustable strap provides a tailored fit.
iST Services: Program Management, Industrial Design, Human Factors Study, 3D Printing, Electronic Circuit Design, Software and Firmware Development, Prototyping, Plastics Tooling and Production Delivery.
Client Response: The successful development of WSDU is a testament to iST’s expertise and experience. USPS needed a partner with extensive barcode scanning knowledge; strong skills in industrial design, electronic, mechanical, software and firmware engineering; understanding of ergonomic wearable design; and solid experience in electronic device prototyping and manufacturing.
- Wearable Scanner & Display Unit exceeded power management expectations
- iST completed all design, development and deliveries within budget and on schedule, even during COVID-19
