Service system
Abstract
The present development consists of an automatic system for
controlling the flow of persons to a plurality of service stations.
The persons wait their turn in a waiting area, and when a service
station is vacant a director sign in front of the waiting area
lights and directs the person in the direction of the vacant
service area. A beacon light at the vacant service area is on at
this time and directs the person to this station. When the person
reaches the service station, automatic sensing means such as a mat
switch or photocell arrangement extinguishes the beacon light and
terminates input to the director sign. This system is particularly
useful in banks, airports, train and bus stations or other places
where persons must wait on lines which move at widely varying
rates.

Claims
What is claimed is:
1. A system for controlling the flow of persons to service stations
comprising:
a. a waiting area wherein persons wait for a vacancy at a service
station;
b. a plurality of service stations;
c. director means in front of said waiting area which alerts a
waiting person to a vacancy at any service station and directs said
person toward a vacant service station;
d. beacon means at each service station which is in a lighted mode
when there is a vacancy at said service station; and
e. beacon actuating means at each service station activated by the
person at that station attaining service, consisting of (1) at
least one photocell which receives at least a set amount of ambient
light when the service station is vacant and thereby controls said
beacon actuating means to be in a lighted mode and said director to
alert said waiting person, and receives less than said set amount
of ambient light when the service station is in use by a previously
waiting person, resulting in said beacon means being in an unlit
mode and said director in a non-alerting mode and (2) variable
resistance means in the photocell circuit for adjusting the
photocell signal relative to the intensity of ambient light
contacting said photocell so that variations in ambient light
intensity do not disrupt said system.
2. A system as in claim 1 wherein said automatic means interrupts
an input to said director means when said photocell receives less
than said set amount of ambient light.
3. A system as in claim 1 wherein the person providing service at
said service station has switch means to manually control said
beacon means and said director means.
4. A system as in claim 3 wherein said service station is a bank
teller station.
5. A system as in claim 3 wherein said service station is an
airline ticket station.
Description
This invention relates to a system for controlling the flow of
persons to a service area. More particularly this invention relates
to a system wherein the presence of a person at the service station
automatically controls a director means and a beacon means which
notify persons of the availability of service at a service
station.
As businesses gear to serve a mass market they are confronted with
the most equitable way to serve their customers. In order to be
profitable there must be some backlog of waiting customers. This is
acceptable by customers, but they do want to be waited on in a fair
and equitable manner. The present technique of having a separate
individual line at each service counter or station yields many
inequities. One line may move very fast, and another rather slow. A
person arriving later than those waiting may be served earlier.
Further when various service stations and counters are opened or
closed there is an inequitable treatment of customers. In general,
customers do not mind waiting a reasonable time for service as long
as they are treated equitably.
The present invention comprises a means for providing equitable
treatment to customers waiting for service at a number of stations
or counters. This system is very useful in banking institutions,
supermarkets, ticket counters such as airline, bus or train ticket
counters and any other place where customers wait and are provided
service at a number of stations. The present system also has the
advantage that transactions at a counter or station can be made in
privacy without those waiting behind in line overhearing the
discussion of the transaction or seeing any of the documents which
are a part of the transaction.
In brief summary, the system consists of a waiting area wherein
persons wait for a vacancy at one of a plurality of service
stations; a director sign in front of the waiting area which alerts
a waiting person to a vacancy at any of the service stations and
directs the person in the direction of the vacant service station;
a beacon sign at each service station which is in a lighted mode
when there is a vacancy and is automatically extinguished when a
person is receiving service at that service station; and further,
automatic control means to extinguish the director sign when all of
the service stations are in use. The automatic control means is
preferably either a switch mat or a photocell arrangement. When the
automatic control means is a photocell arrangement, a customer at
the service station restricts the amount of light to a photocell
which then extinguishes the beacon sign and the input to the
director sign from that station.
It is therefore a prime object of this invention to provide a means
for automatically handling large numbers of persons by a small
number of service personnel.
It is also an object to provide a means for the equitable treatment
of a large number of customers at a small number of service
stations.
It is further an object to provide a means whereby customers can
transact their business in relative privacy.
It is additionally an object to provide a customer regulated system
of service so that the service personnel cannot cause delays in
calling the next customer as is possible in systems controlled
solely by the service personnel.
It is another object to maximize the efficient use of both space
and personnel for the effective service of the customers.
These and further objects are provided by the present system.
Further objects, and the many advantages of this system will become
apparent from the following detailed description and claims in
conjunction with the drawings.

FIG. 3 is the photocell automatic control means.
FIG. 4 is the circuit diagram of the photocell switch means located

FIG. 5 is the circuit diagram of the beacon unit.
FIG. 6 is the circuit diagram of the director unit.
In more detail, the system consists of a waiting area wherein all
of the customers await their turn to proceed to a service station.
This waiting area can consist of a standing line or a row of seats
wherein the people waiting keep moving along in turn. The operation
of the system for a bank use will be explained in greater detail
with reference to FIG. 1. The counter 1 consists of vertical
section 2 which supports the front horizontal shelf 3 and the rear
horizontal shelf 6. Above the horizontal shelves is vertical
section 4 which supports counter shelf 5. Attached to the counter
shelf 5 is beacon sign 7 and in this embodiment director sign 8.
Rectangular enclosure 10 below horizontal shelf 3 is the automatic
photocell means which regulates the servicing of customers. Switch
mat 12 can be used when it is not desired to use photocell unit
10.
In this embodiment the director sign 8 is in the area of the
service stations. This director sign can, however, be located at
essentially any location as long as it is in full view of persons
in the waiting area. Since this director sign is connected to the
remainder of the system by conduit wire, it can be secured to any
stand or fixture. The director exhibited in FIG. 1 has printed
thereon TELLER AVAILABLE and arrows set out below to direct the
person in the waiting area to the available teller. This
instruction is only clearly visible to a person in the waiting area
when the sign is lighted, and when not lighted appears blank. This
can be accomplished by placing a dark glass plate over a template
which has the above message cut out. The lights within the director
can consist of one or more light units either of an incandescent or
fluorescent type. When multiple light units are used there are
preferably a series of baffles within the director.
FIG. 2 is a rear view of the counter of FIG. 1. The switch 13 in
this embodiment is to provide for temporary manual operation of the
system, if such is desired, and to remove the station from
service.
FIG. 3 illustrates the photocell switch for control of the beacon
and input to the director. This switch unit consists of rectangular
shaped enclosure 11.
The front section carries photocells 14 and visors 15. The visors
shield the amount of light which can be incident on the photocells.
FIG. 4 illustrates the preferred circuit for the photocell switch.
The terminals 16 connect thru switch 13 to the beacon light
circuit. The photocells 14 are used as variable resistors. The
dashed circuit lines illustrate the circuitry if it is desired to
use three photocells. In operation, when light impinges on the
photocells the resistance of the photocells 14 decreases and
prevents the voltage on the capacitor 17 to increase enough to
operate diode 18 and no current flows through the circuit. When one
or more of the photocells becomes darkened, the resistance in the
circuit increases with the consequent increase in voltage on the
capacitor 17 to cause diode 18 to actuate. This causes the triac 19
to conduct and operate the circuit. The circuit in this condition
provides an output to a relay which causes an open circuit in the
beacon input. The variable resistor 20 allows adjustment of the
circuit for the amount of total resistance necessary to actuate
diode 18. Resistor 21 has a set resistance and is used to balance
the resistance of the circuit.
When a mat switch is used in place of the photocell switch, the
weight of a person standing on the mat closes the contacts and
provides an input to the beacon relay. An input to the relay causes
the beacon to remain extinguished and interrupts any input from the
beacon to the director.
FIG. 5 illustrates the circuit of a beacon at a service station.
The beacon circuit consists of a switch section 23 and a light
section 24. Power to the beacon circuit is supplied at 22. The
light section consists of the light 25 and flasher 26 which are
operated by means of relay switch 27. Relay 27 controls contacts 28
and 29. Conduits 30 and 31 are part of the low voltage director
circuit. When the relay 27 turns on light 25 it also closes the
circuit formed by these conduits. Contacts 32 and 37 are for
manually putting this service station in use. Switch 37 provides
power, and switch 32 provides for connection of this service
station to the director. Conduits 33 and 34 provide for connecting
other service stations into the director circuit. The input for the
automatic control of the beacon is by means of conduits 35 and 36
from a photocell switch or from a mat switch. This input controls
relay 27. The relay can also be controlled manually by means of
switch 38. Switch 38 is a momentary switch and is closed when the
system is being operated automatically. When the system is
temporarily being operated manually, this momentary switch 38 is
manually operated thereby controlling the relay.
FIG. 6 sets out a preferred director circuit. Power is supplied to
the circuit at 39. Fuse 40 is a safety device. Transformer 41
reduces the voltage, and rectifier 42 converts the reduced voltage
from AC to DC. Conduits 43 and 44 go to beacons located in one
direction, and conduits 45 and 46 to beacons located in the other
direction. The conduits 43 and 44 control relay 47, and conduits 45
and 46 control relay 48. Relays 47 and 48 each control lights 49
and 50. Relay 47 further controls flasher 51 and light 52. Relay 48
further controls flasher 53 and light 54. This circuit is the
preferred circuit for controlling the director 8 set out in FIG. 1.
The director 8 contains four lights, lights 49 and 50, providing
illumination for TELLER AVAILABLE and lights 51 and 52 providing
illumination for the direction arrows.
In operation, a customer waits in the waiting area and watches the
director. When it illuminates TELLER AVAILABLE and a direction
arrow lights up, the person walks in that direction until he comes
to the teller whose beacon is on. When the person steps in front of
the teller to transact business, the beacon and the director
automatically extinguish by means of a mat switch, photocell switch
or equivalent switch arrangement. When the person has finished
transacting his business and leaves the area, the beacon and
director automatically switch on and page another customer. If a
customer is slow in leaving the area, the beacon and director can
be manually controlled.
The present system can be modified in various ways to adopt it to
various uses. Such modifications are, however, within the present
system.
