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.

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

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.

Possible Settings

• Mainly hospitality environments:– Restaurants– Hospitals– Old age homes– Department Stores

• Therefore, these are our target consumer groups.

Our Competitors’ Designs

• High-tech solutions :touch screen order menu. elegent solutionX costly investment

• The “WaiterCaller” wireless paging system alerts a waiter to a table’s requestX does not identify purpose of pagingX does not enable waiter to update the kitchen

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.

Our Prototype:

• A prototype design customized to cater for a restaurant environment

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

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

How the SerCal Works

• Hardware:SerCal Table Unit

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

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

Software Design

• Two parts:– Kitchen– Server

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

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.
