The E-host is a compact device for use mainly in restaurants and bars to more easily request attention from a server or steward. It can also be used in any situation where people are seated and need to request the assistance of an individual whose job it is to provide such help. Seated individuals sometimes have to wait long periods before they can attract the attention of a server or helper for assistance. Research suggests that over 60% or restaurant diners are negatively affected when they cannot get immediate attention from a server or steward.
The E-host is a compact device that embodies LED (light emitting diode) technology. An internal circuit including a programmable chip shall be programmed to control the LED function including the color of light emitted. The E-host uses LEDs to emit light and thus attract attention when service is required.
The E-host will be a compact device attached to or close to the edge of a table. When turned on by means of pressing a small switch, the enclosed LED will light up and shine through an acrylic/plastic window. The device may contain more than a single LED. An important aspect of this device is its use of more than one color in a light sequence to indicate wait time. For example; when the device is turned on, the light coming out through the window may be white. After two minutes, the light shining from within the device might change to green to indicate that assistance has been required at that table for at least two minutes. The light may also then turn to red after an additional two minutes to indicate that the total wait time at that table has been at least four minutes. Upon seeing the light come on, not only will a server or helper become aware that individuals at that particular table require assistance but also how long they have been waiting. For seated guests, it will eliminate wait time and continuously seeking out servers.
a shows the 3D graphic depiction of the E-host. The on/off switch is used to turn the device on and off. Attachment screws help to attach the device to a table by fastening the table attachment to the underneath of the table. The fastening screws on the front of the device only serve to maintain the structural integrity of the E-host's casing. The acrylic window assists in diffusing the light produced internally by the LED.
b shows the preferred attachment method of the E-host to the table so that, except for the on/off switch, very little of the rest of the device protrudes over the table's top edge.
The casing of the device will be made of ABS or any metal alloy. To achieve the desired shape, a mold must be created which will give the molten alloy or plastic polymer its shape on cooling. For the acrylic window on the front of the E-host, a mold must also be created to achieve the desired shape. The window diffuses the light produced so a person looking at the device from a short distance may easily see it. The on/off switch may be ABS or any metal alloy and is also created by using a mold. The switch must be spring loaded when attached to the casing allowing it to re-emerge when depressed. The spring loading system should preferably, also be the switch mechanism and extend down to the power source circuit. When depressed, the switch mechanism should cause the power source circuit to become complete and send an electric current to the circuit board, which lights up the LED. The power source can be a series of batteries or an AC current wired into the device from an external source.
The role of the circuit board in the device is to connect all internal components and re-route the electric current from the power source to the LED. The pattern or circuit on the circuit board may be created by direct copper plating on a blank board or etching, the process that involves chemically removing the unwanted copper from a plated board. The circuit board also holds the program chip. The chip is programmed to control all aspects of the lighting function of the LED/s including;
When all the internal components are assembled and enclosed in the casing, the E-host will be attached to a table, preferably, by means of screws bolted to the underneath of the table using the table attachment (as in diagram 1a). For example; when the switch is pressed, this activates the E-host. A white light will shine through the acrylic window for two minutes. If the switch has not been pressed again to turn off the device after that time length, the light will turn to green for an additional two minutes. If the switch, still, has not been pressed again to turn off the device after the 4 minute length, the light will turn to red and remain that color until the device is eventually turned off. At any stage, pressing the switch can turn off the device. When turned on again, the device will start again by emitting the first color in the programmed sequence. The color sequence serves to alert an individual serving that table of how long the light has been on or how long the seated individuals have needed assistance.
