  2. Outline • Why SWIS? • The problem • Our competitors • Our solution and targeted market • Product overview • Our design • Live demonstration • Production timeline • Budget • Funding • Conclusion • Acknowledgements

  3. Why SWIS? • Short-range : Suitable for enclosed environments and built up areas. • Wireless: Reduce clutter and obstruction due to wiring. • Innovative: Simple implementations that achieve practical results. • Solutions: Products that solve common daily problems.

  4. The Company • Aron McKinnon, the Chief Executive Officer (CEO) of SWIS • Raymond Tan, the Chief Technology Officer (CTO) of SWIS • Peter Chen, Chief Quality Assurance Officer of SWIS

  5. The Problem: • Customers sometimes wait for extended periods of time to be served. • Due to failure of being alerted, service providers otherwise kept busy, are left idling • Decreased productivity due to time wastage resulting from lack of communication. • Decrease in productivity may ultimately lead to lower income and poor customer appraisal.

  6. Possible Settings • Mainly hospitality environments: • Restaurants • Hospitals • Old age homes • Department Stores • Therefore, these are our target consumer groups.

  7. Our Competitors’ Designs • High-tech solutions : touch screen order menu. • elegent solution • costly investment • The “WaiterCaller” wireless paging system • alerts a waiter to a table’s request • does not identify purpose of paging • does not enable waiter to update the kitchen

  8. Our Solution: • Designing a short-range wireless product for numerous consumer venues/ hospitality environment. • Allows customer to electronically page individual service providers for attention. • Added feature of allowing internal communication amongst service providers. • Allow page request display in order to reduce unproductive travelling time.

  9. Our Prototype: • A prototype design customized to cater for a restaurant environment

  10. Product Overview • SWIS SerCal (Server Caller) • Example scenario : Restaurant • Bluetooth wireless scheme • 3 component units

  11. SerCal Components • Kitchen Unit: • Central communication hub. (Computer) • Updates waiters on customers paging and orders ready. • Server Unit: • Portable Unit (eg. PDA) carried by waiters • Displays customer & kitchen paging status • Updates kitchen on table orders. • Table Unit: • Pages for waiters’ attention

  12. How the SerCal Works

  13. SerCal Design • Hardware: SerCal Table Unit

  14. SerCal Design • Hardware: Logitech V270 Bluetooth wireless mouse • Bluetooth 1.2 wireless technology • Adaptive frequency hoping • Battery life up to 2200 hours • Features low battery indicator light • 1000 dpi optical engine • Uses 2 AA batteries • 3 push buttons with scroll wheel function

  15. SerCal Design • Hardware: Pushbuttons (final design): NKK single element DPDT LED UB series • Double pole double through • PCB mountable with gold contacts • Power level 5A at 30V DC • Dielectric strength 0.4VA • Mechanical life > 1000000 operations • Electrical life > 10000 operations • Operation temperature -25 – 50 degrees Celsius • LED rating: 1.85V at 20mA • CSA certified

  16. Software Design • Two parts: • Kitchen • Server

  17. Kitchen Software • The kitchen software is responsible for • Receiving signals from the Table Units • Relay the signals to the desinated Server Unit • Receive orders from the Server Unit

  18. Server Software • The Server software will: • Allow the user to take orders and send to the Kitchen Unit. • Receive signals from the Kitchen Unit that tells the server what table is in need.

  19. Flowchart

  20. Screenshots

  21. Implementation & training • Users will be instructed by SWIS engineers, or use the device under the supervision of SWIS engineers. • Manuals will be provided, which include: • The customer manual • for an audience with minimal technical expertise • one page leaflet with proper instrument care and sensor placement information

  22. Implementation & training • Server worker manual • for an audience with general experience with electronics device • provide training for complete device usage of two modules: Table Unit and Server Unit • Service crew manual • for an audience with expertise in electronic device • complete training, setup, troubleshooting, and device characteristics information for all three modules: Table Unit, Server Unit and Kitchen Unit.

  23. Production timeline

  24. Budget

  25. Funding • Engineering Science Student Endowment Fund of $50 • Remaining costs were borne by SWIS.

  26. Why SWIS SerCal? • Greatly reduces redundant waiting time • Effective and efficient use of resources • Real time request/status updates (important for time critical services, ie. hospital) • Increased productivity • Improve customers’ impression!

  27. Acknowledgements We would like to thank the following people: • Dr Andrew Rawicz for his guidance, suggestions and endorsement of funding from the engineering science endowment fund. • Mr Mike Sjoerdsma for imparting us with valuable knowledge on project documentation and presentation. • Mr Brad Oldham and Ms Lisette Paris Shaadi for taking time off to cater for consultation sessions and providing advice with regards to our design implementation
