Additionally, the server unit can further include charging prongs 26a for allowing the unit to interface with a charging station in order to keep the power source 26 charged at all times, when the power source 26 includes rechargeable batteries.
The receiver 24 can act to receive the transmitted service request signal 14a from the transmitter 14 of one or more table units 10. In one preferred embodiment, the receiver 24 can include a variable radio wave receiver having a unique radio frequency chip capable of receiving and translating a plurality of independent radio frequencies associated with a particular service request of a particular table unit 10. These received signals are ultimately sent to the processor 22 and/or the memory 23 of the server unit 20. Upon receipt of one or more of these signals, the processor can activate the status indicator light associated with the service request signal of the particular table unit that sent the request. This can be accomplished in accordance with known techniques, such as assigning different frequencies to each of the table units and/or including an identifier signal within each transmission, for example.
A plurality of status indicator lights 25 can be disposed on the server unit 20 in order to indicate a service request from one or more of the above described table units. The indicator lights preferably including multiple green LED's 25a and multiple red LED's 25b. To this end, each of the lights 25 can be displayed in a grid-like manner wherein one green light 25a and one red light 25b are associated with a single table unit 10a-10x of the system.
In operation, the system 100 can allow a patron to quickly and easily communicate a service request to their waiter in an electronic manner. The process can be initiated by a user selecting an appropriate button 15a or 15b from on the table unit 10. Upon depressing one of the buttons 15a and 15b, the processor 12 can instruct the transmitter 14 to send an appropriate signal 14a that includes a message corresponding to M1 or M2, respectively, while simultaneously activating the corresponding indicator 16 of the table unit.
The transmitted frequency can be received by the receiver 24 of the server unit 20 and decoded by the processor 22 in accordance with known transmission, reception and coding methodologies. Upon receipt of the signal, the processor 22 can determine which of the table units 10a-10x transmitted the request and whether the request indicates message M1 (come now) or message M2 (do not disturb), for example. Once this determination is made, the processor 22 can activate the appropriate indicator light 25a or 25b for the selected table unit.
Once a particular button 15 has been pressed, the indicator lights 16 and 25 associated with that button will preferably remain illuminated until instructed otherwise. As such, the lights 16 and 25 can be extinguished when a different button 15 on the same table unit 10 has been pressed, thereby activating a different light, or by repressing the same button 15 which will extinguish the associated lights.
In another embodiment, the server unit 20 can also include additional forms of notification units. For example, the device can also include an audio jack 28 and a vibration unit 29 suitable for providing non-visual notification to a user regarding a received service request.
The audio jack 28 can function to interface with a headphone and/or ear jack, for example, for sending an audible notification tone to the user upon receipt of a signal 14a. Likewise, the vibration unit can include any number of known devices suitable of creating a strong vibration of the main body 21 which can be easily felt by a server wearing the device. Each of these components and their associated hardware are extremely well known in the art, and can function to alert a server that they have received a service request, the specifics of which can be determined by looking at the indicator lights 25.
As shown in FIG. 3, the restaurant service indicator system can be presented as a kit for use in virtually any industry. As shown, the kit 30 can include up to six table units 10a, 10b, 10c, 10d, 10e and 10f, a single server unit 20, a charging station 31 and an instruction manual 33.
