Definitions
- the various embodiments described herein generally relate to elevator installations. More particularly, the various embodiments described herein relate to a system and method for managing passenger traffic in elevator installations.
- Elevator installations are expected to operate as efficiently as possible.
- An elevator installation equipped with a destination call control system, provides for an improved efficiency compared to a conventional up/down control system. This is, for example, because a destination control system requires a passenger to enter the destination floor already at a floor terminal before boarding an elevator car (entry of such a call is referred to as "destination call").
- destination call In response to such a destination call, an elevator car is allocated to service that destination call, as described for example in WO2014/195564 .
- a conventional up/down control systems allows the passenger to enter a destination floor only from within the elevator car (entry of such a call is referred to as "car call").
- An elevator installation can be configured for as high an efficiency as technically feasible, but behavior of passengers may negate these efforts. There is, therefore, a need for a technology that facilitates improving the efficiency of the elevator installation.
- an aspect of such a technology involves a method of operating an elevator installation.
- the method includes receiving a destination call of a passenger at a computer, wherein the destination call defines a boarding floor and a destination floor. It includes further allocating an elevator car to service the destination call of the passenger, and assigning a zone inside the elevator car for the passenger to occupy after entering the elevator car at the boarding floor.
- the method includes also communicating the allocated elevator car and the assigned zone to the passenger.
- An elevator installation having an elevator car and a controller unit.
- the elevator car is movable between floors of a building.
- the controller unit processes at least one received destination call of a passenger and controls the elevator car in accordance with at least one destination call.
- a destination call defines a trip from a boarding floor to a destination floor.
- the controller unit includes a computer that allocates an elevator car to service the destination call of the passenger, that assigns a zone inside the elevator car for the passenger to occupy after entering the elevator car at the boarding floor, and which communicates the allocated elevator car and the assigned zone to the passenger.
- the technology described herein provides for an alternative way of organizing and influencing passenger traffic at an elevator stop.
- passenger traffic occurs rather randomly so that passengers that need to disembark first are often in the back of an elevator car, with the effect that their leaving the car is slowed down by passengers standing in their way.
- passengers nearest to an elevator door i.e., an exit of the elevator car
- step out of the car to let disembarking passengers pass. This negatively affects the efficiency of the elevator installation, for example, since doors need to stay open for a longer period of time or closing doors need to be reversed because of passengers blocking the closing doors.
- the technology alleviates these issues by instructing passengers to occupy assigned zones within the car at the beginning of a trip or after an intermediate stop, which may be beneficial in a heavily loaded car during peak traffic times.
- the way passengers exit the elevator car is no longer left to random movement, but occurs in a more efficient way because passengers exiting before other passengers will occupy a zone near an elevator door. Those exiting last will at least initially occupy a zone farther away from an elevator door. Ideally, those staying in the elevator car will no longer stand in the way of those disembarking.
- the incident of a door reversal can thereby be reduced which leads to reduced trip times, especially for heavily loaded cars during peak traffic times.
- passengers do not have to wonder where to stand, or even feel uncomfortable with asking other passengers to move aside so they can get off the car.
- Communicating the allocated elevator car and the assigned zone to a passenger can occur in a variety of ways.
- One or more visual indications or audible indications may inform (show or announce) a passenger about the assigned zone.
- visually impaired passengers benefit from audible indications.
- One or more indicators inside the elevator car can be configured as markings on an interior surface of the car, a display or a loudspeaker.
- a loudspeaker and a display may be combined in a multimedia set that may provide additional information explaining the reasons for assigning the zones. This may result in a higher acceptance of the technology described herein and compliance with the instructions to occupy an assigned zone.
- the marking on the surface may be colored and/or numbered areas. They may also be configured as illuminated markings that can be dynamically controlled by the controller unit. Such markings allow, for example in connection with additional instructions over a display, reassigning the zones during a trip. Such flexibility allows the technology to be adapted to a particular elevator installation, e.g., regarding design requirements (e.g., LED illuminated markings) or passenger traffic needs (e.g. an office building may experience peak traffic during lunch time, requiring reassignment to improve transport efficiency). Additional flexibility is achieved through resizing the zones to accommodate passengers boarding at an intermediate stop.

In such a situation, the area P1, P2, P3 assigned to that group may be larger than the other zones P1, P2, P3.
- the elevator installation 1 may, therefore, be configured to resize the zones P1, P2, P3 based on a space requirement of individual passengers or groups of passengers, either at the initial boarding floor L1, L2, L3 or at an intermediate destination floor.

Abstract
To more efficiently organize passenger traffic at an elevator stop, an elevator operational method includes receiving a destination call of a passenger at a computer (8). The destination call defines a boarding floor (L1, L2, L3) and a destination floor (L1, L2, L3). The method allocates an elevator car (10) to service the destination call of the passenger, and assigns a zone (P1, P2, P3) inside the elevator car (10) for the passenger to occupy after entering the elevator car (10) at the boarding floor (L1, L2, L3). The method communicates the allocated elevator car (10) and the assigned zone (P1, P2, P3) to the passenger.
Description
- The various embodiments described herein generally relate to elevator installations. More particularly, the various embodiments described herein relate to a system and method for managing passenger traffic in elevator installations.
- Elevator installations are expected to operate as efficiently as possible. An elevator installation, equipped with a destination call control system, provides for an improved efficiency compared to a conventional up/down control system. This is, for example, because a destination control system requires a passenger to enter the destination floor already at a floor terminal before boarding an elevator car (entry of such a call is referred to as "destination call"). In response to such a destination call, an elevator car is allocated to service that destination call, as described for example in
WO2014/195564 . In contrast, a conventional up/down control systems allows the passenger to enter a destination floor only from within the elevator car (entry of such a call is referred to as "car call"). - An elevator installation can be configured for as high an efficiency as technically feasible, but behavior of passengers may negate these efforts. There is, therefore, a need for a technology that facilitates improving the efficiency of the elevator installation.
- Accordingly, an aspect of such a technology involves a method of operating an elevator installation. The method includes receiving a destination call of a passenger at a computer, wherein the destination call defines a boarding floor and a destination floor. It includes further allocating an elevator car to service the destination call of the passenger, and assigning a zone inside the elevator car for the passenger to occupy after entering the elevator car at the boarding floor. The method includes also communicating the allocated elevator car and the assigned zone to the passenger.
- Another aspect involves an elevator installation having an elevator car and a controller unit. The elevator car is movable between floors of a building. The controller unit processes at least one received destination call of a passenger and controls the elevator car in accordance with at least one destination call. A destination call defines a trip from a boarding floor to a destination floor. The controller unit includes a computer that allocates an elevator car to service the destination call of the passenger, that assigns a zone inside the elevator car for the passenger to occupy after entering the elevator car at the boarding floor, and which communicates the allocated elevator car and the assigned zone to the passenger.
- Briefly, the technology described herein provides for an alternative way of organizing and influencing passenger traffic at an elevator stop. In known elevator installations, passenger traffic occurs rather randomly so that passengers that need to disembark first are often in the back of an elevator car, with the effect that their leaving the car is slowed down by passengers standing in their way. Sometimes, especially for heavily loaded cars during peak traffic times, passengers nearest to an elevator door (i.e., an exit of the elevator car) need to step out of the car to let disembarking passengers pass. This negatively affects the efficiency of the elevator installation, for example, since doors need to stay open for a longer period of time or closing doors need to be reversed because of passengers blocking the closing doors.
- The technology alleviates these issues by instructing passengers to occupy assigned zones within the car at the beginning of a trip or after an intermediate stop, which may be beneficial in a heavily loaded car during peak traffic times. The way passengers exit the elevator car is no longer left to random movement, but occurs in a more efficient way because passengers exiting before other passengers will occupy a zone near an elevator door. Those exiting last will at least initially occupy a zone farther away from an elevator door. Ideally, those staying in the elevator car will no longer stand in the way of those disembarking. The incident of a door reversal can thereby be reduced which leads to reduced trip times, especially for heavily loaded cars during peak traffic times. Also, passengers do not have to wonder where to stand, or even feel uncomfortable with asking other passengers to move aside so they can get off the car.
- Communicating the allocated elevator car and the assigned zone to a passenger can occur in a variety of ways. One or more visual indications or audible indications may inform (show or announce) a passenger about the assigned zone. Of course, visually impaired passengers benefit from audible indications. One or more indicators inside the elevator car can be configured as markings on an interior surface of the car, a display or a loudspeaker. A loudspeaker and a display may be combined in a multimedia set that may provide additional information explaining the reasons for assigning the zones. This may result in a higher acceptance of the technology described herein and compliance with the instructions to occupy an assigned zone.
- The marking on the surface may be colored and/or numbered areas. They may also be configured as illuminated markings that can be dynamically controlled by the controller unit. Such markings allow, for example in connection with additional instructions over a display, reassigning the zones during a trip. Such flexibility allows the technology to be adapted to a particular elevator installation, e.g., regarding design requirements (e.g., LED illuminated markings) or passenger traffic needs (e.g. an office building may experience peak traffic during lunch time, requiring reassignment to improve transport efficiency). Additional flexibility is achieved through resizing the zones to accommodate passengers boarding at an intermediate stop.

The improved technology itself, however, as well as other features and advantages thereof, are best understood by reference to the detailed description, which follows, when read in conjunction with the accompanying drawings, wherein:

Building users and occupants have access and egress to various floors L1, L2, L3 of thebuilding 2 using theelevator installation 1. Depending on a particular configuration of thebuilding 2, the floor L1 may be a lobby of an office building or a hotel. In the illustrated embodiment, theelevator system 1 includes anelevator car 10, having adoor 6, and a central controller 12 (also referred to as elevator controller 12 (EC)) that acts on adrive 14 to move theelevator car 10, for example suspended by one ormore tension members 16, in anelevator shaft 18, from one of the floors L1, L2, L3 to another. Atension member 16 may by a steel rope having a round cross-section, or a group of (steel or non-metallic) cords embedded in synthetic material having a non-round cross-section, e.g., a rectangular cross-section. - The general physical structure of the
elevator installation 1 corresponds to the physical structure of a generally known elevator installation.

It is contemplated that, depending on a particular embodiment of theelevator installation 1, the configuration and disposition of these elements in ashaft 18 may vary. For example, thedrive 14 may be arranged in a separate machine room or directly in the shaft 18 ("machine room less elevator") at the top, as shown, or at the bottom of theshaft 18. The operation of such anelevator installation 1 is known to the skilled person and, therefore, not described here. - In one embodiment, the
elevator installation 1 is equipped with a destination call control system, for example, including a SchindlerID® or PORT Technology System, both being available from Schindler. As a destination call control system is typically used in connection with one or more groups of elevators, it is contemplated that theelevator installation 1 can include more than oneelevator car 10, each in aseparate shaft 18 and controlled by aseparate controller 12 and drive 14. If groups of elevators are defined, a group controller controls the individual groups. For illustrative purposes, however, theelevator installation 1 ofFig. 1 is illustrated as having only one elevator. - The
elevator installation 1 ofFig. 1 includes further user terminals, forexample floor terminals 5 located on the floors L1, L2, L3. Eachfloor terminal 5 includes auser interface 4 that allows a passenger to enter a destination call and to receive information about the elevator that has been allocated to service that destination call. It is contemplated that in certain buildings 2 a floor L1, L2, L3 may be provided with more than onefloor terminal 5. Thefloor terminals 5 are communicatively coupled to acomputer 8, which is part of the destination call control system. - Also, it is contemplated that a destination call may be entered and information may be received using an electronic
mobile device 7 as user terminal, such as a mobile phone, smart phone, tablet PC or the like. Such amobile device 7 may communicate with theelevator installation 1 via a wireless connection, e.g., using a mobile communications network, a local network within thebuilding 2 and/or near-field communications (NFC) or Bluetooth communications between a mobile device andfloor terminal 5 or RF/Bluetooth beacons. Depending on a particular configuration of theelevator installation 1 in thebuilding 2, some or all of thefloor terminals 5 may be omitted. - A communicative connection or coupling as used herein is a direct or indirect connection, which enables the unidirectional or bidirectional communication between two entities. Via such a connection or coupling, data signals and/or control signals are transmitted in a manner (e. g., regarding electrical characteristics and data protocol) known to the skilled person. The connection or coupling may be achieved by an electrical wiring system (either as a system of point-to-point connections or as an electrical bus system, where entities connected to the bus system can be addressed), a radio system or a combination of a radio system and an electrical wiring system.
Fig. 1 shows the communicative coupling throughlines line 20 extends between thecomputer 8 and theelevator car 10, and theline 22 extends between thecomputer 8 and thefloor terminals 5. In one embodiment, theline 22 is a bus system to which thefloor terminals 4 are connected. - As described below in more detail, the
computer 8 processes a destination call, allocates an elevator to service the destination call (i.e., to transport a passenger to a desired destination floor), assigns a zone P1, P2, P3 within theelevator car 10 to the passenger entering the destination call, and communicates with thefloor terminals 5 and thecontroller 12. For that purpose, thecomputer 8 is communicatively coupled to theelevator controller 12 and thefloor terminals 5. Thecomputer 8 and theelevator controller 12 together may be considered to form a controller unit. The skilled person recognizes that thecomputer 8 or its functionality of, e.g., processing a destination call may be implemented, for example, in theelevator controller 12, in one of thefloor terminals 5, or in an electrical component of thebuilding 2, e.g., in an access control system that controls access to thebuilding 2, floors L1, L2, L2 and/or rooms of thebuilding 2. In such a case, the separately showncomputer 8 might be omitted fromFig. 1 . Depending on a particular embodiment, the implementation of the communicative connection or coupling changes accordingly. As a matter of principle,Fig. 1 , therefore, is to be viewed as an exemplary embodiment. - The
user interface 4 of afloor terminal 5 may be configured in one of several ways; for example, it may include a keyboard, a touchscreen, an electronic reader, or a combination of these components. As mentioned above, a mobile device may also serve as a user interface. A passenger may enter a destination call using one of these components. These components are further configured to communicate the allocated elevator and the assigned zone P1, P2, P3 to the passenger, via a visual indication and/or an audible indication. Depending on its configuration, theuser interface 4 displays the allocated elevator and the assigned zone P1, P2, P3 on a display. In the shownelevator installation 1 the display is associated with a keyboard or an electronic reader, or on a touchscreen. In the example ofFig. 1 , a passenger entered a destination call on floor L1 and theuser interface 4 displays in response the allocated elevator as "Elevator A" and the assigned zone as "Location P1". To assist, for example, visually impaired passengers theuser interface 4 may announce the allocated elevator and the assigned zone P1, P2, P3 through a loudspeaker, either exclusively or in addition to displaying this information. - The
user interface 4 is in one particular embodiment configured to read information from an information carrier carried by a person/passenger. For that purpose, theuser interface 4 is equipped with a reader to read data from that information carrier when it is presented to the reader. The data may represent an authorization to operate thefloor terminal 5, for example, only registered employees or registered hotel guests may use the elevators. In one embodiment, the information carrier has a form factor that corresponds to a credit card or an employee badge. Depending on a particular configuration, the information carrier includes an embedded memory chip having leads to the surface of the information carrier, an embedded RFID transponder in connection with a memory chip, an optical code on the surface (e.g., a barcode or QR code), or a combination of these technologies. In the alternative, the functionality of the information carrier may be implemented in an electronic mobile device (e.g., mobile phone, smart phone or tablet PC). These devices may display optical codes, and may also allow radio communication with other electronic devices using known technologies such as Bluetooth or NFC (near field communication). It is contemplated that the reader is compatible with the technology, or the several technologies, used by the information carrier. - In the embodiments described herein, a passenger not only receives information about the elevator that has been allocated for the trip to the destination floor, but also about the zone P1, P2, P3 that has been assigned to the passenger inside that elevator's
car 10. For the latter purpose, thecar 10 is configured to indicate - under control of the computer 8 - the assigned zone P1, P2, P3 to the passenger so that the passenger knows where to stand inside thecar 10 during the trip. Thecar 10 may have anindicator 9 to indicate the space or location in at least one of several ways. InFig. 1 , the zones P1, P2, P3 are indicated on the car floor through marked areas, e.g., colored and/or illuminated border lines, illuminated or illuminable floor tiles, projected colored or numbered areas. Known LED technology may be used to illuminate such markings. In this case, the zones P1, P2, P3 may be viewed as indicators. In addition to such marked areas, theindicator 7 may include a loudspeaker to produce an audible announcement that instructs the passenger where to stand during the trip. It is contemplated that indicating the zones P1, P2, P3 to a passenger may also be achieved via a wall or ceiling of thecar 10, by means of light beams, or other means used to provide instructions to individual people, such as a multimedia set. Further, it is contemplated that the number of zones P1, P2, P3 may vary, for example, depending on a size of thecar 10, or the number of registered passengers. In addition, it is contemplated that more than one passenger (i.e., a group) may be assigned to a zone P1, P2, P3. - As mentioned above, the
elevator installation 1 is equipped with a destination call control system. As is known in the art, the destination call control system is based on the principle of grouping passengers with same destinations to service the calls as efficiently as possible. The destination call control system processes a destination call and assigns - e.g., with respect to waiting time, travel time or number of stops - the most suitable elevator to that destination call. More than one destination call and, hence, several passengers may be allocated to asingle car 10, which may have more than one stop. The destination call control system, therefore, identifies every passenger by destination within theelevator installation 1, and "knows" where a passenger boards and disembarks thecar 10. Since that information is available within the destination call control system, thecomputer 8 can generate personalized directions and guidance regarding which zones passengers should occupy when they first enter thecar 10. In one embodiment, thecomputer 8 may further direct the passengers to alternative locations (zones P1, P2, P3) inside thecar 10 as the trip progresses and more people exit and enter thecar 10. - That process is described in more detail with reference to allocation examples shown in
Figs. 2a, 2b, 3a, and 3b that show top views of the inside of theelevator car 10. Theelevator car 10 is shown as having a single exit via theelevator door 6. However, another embodiment of anelevator car 10 may have, for example, two exits via two doors on opposite or adjacent sides of thecar 10. To describe the assignment of a zone P1, P2, P3 relative to an exit, terms like near, close, away or farther away may be used. In acar 10 as depicted inFigs. 2a, 2b, 3a, and 3b , terms like front, rear or back may be suitable as well. -
Fig. 2a is a schematic illustration of a first allocation example at an initial state, andFig. 2b is a schematic illustration of the first allocation example at a subsequent state.Fig. 2a shows one example of a possible allocation example for three groups of people entering thecar 10 at a floor L1, L2, L3, wherein a group may include one or more passengers. In that example, the passenger(s) in the first group would be the first to exit. The first group is assigned to the zone P1 located closest to thedoor 6 of thecar 10. At the time the passenger enters the destination call, theuser interface 4 instructs the (first group) passenger, for example, to take "Elevator A" and to occupy "Location P1", as illustrated inFig. 1 . The passengers in the second and third groups would also enter "Elevator A", but would get assigned zones P2 and P3, respectively. These passengers would stay in thecar 10 for a longer time than the passenger in the first group, but not too different from each other. -
Fig. 2b schematically illustrates the first allocation example at an exemplary subsequent state. At that state, it is assumed that thecar 10 is at a first stop, where the first group is disembarking thecar 10. When the first group has disembarked, the remaining passengers could be invited, e.g., by thecomputer 8 controlling theindicator 7, e.g., the markings in thecar 10, to move from the initially assigned zone P1, P2, P3 to a newly assigned zone P1, P2, P3. For example, with the zone P1 now being available, the group in the zone P2 could move to the zone P1. Of course, passengers will move around naturally once other passengers get off thecar 10, but now there is an assigned place to go. InFig. 2b , the movements of the passengers are indicated through arrows. As mentioned above, such a reassignment may be assisted by additional explanations, for example, using a multimedia set. -
Fig. 3a is a schematic illustration of a second allocation example at an initial state.Fig. 3a also illustrates three groups of passengers entering thecar 10 at a floor L1, L2, L3. Those in the first group will be the first to exit; thefirst group 1 is, therefore, located closest to thecar door 6. At the time of entering the destination call(s), thecomputer 8 would - via the user interface 4 - instruct each passenger of the first group to take "Elevator A" and to occupy "Location P1". The passenger(s) in the second group will travel longer than those in the first group, and would also enter "Elevator A", but would get assigned to "Location P2". The passenger(s) of the third group will travel the farthest and will stay in thecar 10 until the first and second groups have exited; the third group is assigned to zone P3, which is towards the rear of thecar 10, or farthest away from thedoor 6. -
Fig. 3b schematically illustrates the second allocation example at an exemplary subsequent state. At that state, it is assumed that thecar 10 is at a first stop, where the first group has disembarked the car 10 (as indicated by an arrow). For illustrative purposes, the first group is shown outside thecar 10 and labeled corresponding to its previous location (zone P1) inside thecar 10.Fig. 3b further illustrates adjusted locations in zones P2, P3 for the passengers of the remaining groups. - Although not explicitly shown in
Figs. 2a, 2b, 3a, and 3b , it is contemplated that the zones P1, P2, P3 may have varying sizes, e.g., when thecar 10 on its travel from the initial boarding floor L1, L2, L3 to a final destination floor stops at an intermediate destination floor and a larger group of passengers with the same destination boards thecar 10. In such a situation, the area P1, P2, P3 assigned to that group may be larger than the other zones P1, P2, P3. In one embodiment, theelevator installation 1 may, therefore, be configured to resize the zones P1, P2, P3 based on a space requirement of individual passengers or groups of passengers, either at the initial boarding floor L1, L2, L3 or at an intermediate destination floor. The resizing may, for example, also be triggered in case a wheelchair needs to be accommodated. -
FIG. 4 shows a block diagram of an exemplary embodiment of a computer 8 (which may be part of an access control system control unit, part of theelevator controller 12, part of a reader, or part of a database system) that can be used with one or more of the embodiments disclosed herein. Thecomputer 8 comprises one ormore processors 24. Theprocessor 24 is coupled to amemory 26, which comprises one or more computer-readable storage mediastoring software instructions 28 and a database. The computer-readable storage media can comprise, for example, one or more of optical disks, volatile memory components (such as DRAM or SRAM), or nonvolatile memory components (such as hard drives, Flash RAM or ROM). - When executed by the
processor 24, thesoftware instructions 28 cause theprocessor 24 to perform one or more of the method steps disclosed herein. Further embodiments of thecomputer 8 can comprise one or more additional components. Thecomputer 8 can be connected to one or more other computers or electronic devices through an input/output component (interface) 30. In at least some embodiments, thecomputer 8 can connect to other computers or electronic devices through a network. In particular embodiments, thecomputer 8 works with one or more other computers, which may be located locally, remotely, or both. One or more of the disclosed methods can thus be performed using a distributed computing system. - With the understanding of the structure of the
elevator installation 1 and the functionalities of its components described in connection withFig. 1 - Fig. 4 , various embodiments of a method of operating theelevator installation 1 are described in connection withFig. 5 . This figure describes an exemplary flowchart of a method of operating theelevator installation 1. - Referring to
Fig. 5 , the method starts at a step S1 and ends at a step S9. At a step S2, the method waits for the input of at least one destination call, as indicated through a YES branch and a NO branch. At a step S3, every received destination call is registered, i.e., the boarding floor and the desired destination floor. In the embodiment ofFig. 1 , thecomputer 8 receives and registers each destination call. - At a step S4, the
computer 8 processes each destination call, and allocates in a step S5 an elevator (i.e., car 10) to each destination call. Depending on the prevailing traffic volume within thebuilding 2, only one passenger may be allocated to an elevator. Thecar 10 then stops only at the destination floor. It is, however, also possible that more than one destination call, and, hence, several passengers are assigned to thesame car 10. The destination floors may differ in such a case. On its way to the last destination floor, thecar 10 then stops at one or more intermediate destination floors to allow passengers to board or disembark. Since every destination call is registered, thecomputer 8 knows after processing the destination calls and typically before starting a trip to service the destination calls, if and where passengers board and disembark. - At a step S6, the method determines if multiple stops are planned for the trip. If in step S6 the method determines that there is at least one intermediate stop between the first boarding floor and the (final) destination floor, the method proceeds along the YES branch to a step S7. In step S7, the method causes the
computer 8 to assign a location inside thecar 10 to each destination call. The assigned location is communicated to thefloor terminal 5 at which the respective destination call has been entered, as described above. Once all destination calls are processed and the elevator and locations have been assigned, the planning of the trip is done, and the method proceeds to a step S8 and executes the trip. - At step S6, if there are no intermediate stops between the first boarding floor and the (final) destination floor, the method proceeds along the NO branch to step S8. In step S8, the method causes the
elevator controller 12 to execute the trip according to the destination call. - In an alternative embodiment, step S6 may be omitted. In that case, the assignment of a zone in step S7 is always performed. However, if there is no (intermediate) destination floor, only a (final) one, the entire inside of the
car 10 may be viewed as the "assigned" zone. - It is contemplated that the flowchart of
Fig. 5 may be expanded by showing additional steps. For example, additional steps may show the reassigning of the zones P1, P2, P3 in case intermediate stops occur, as explained above with reference toFigs. 2a and 2b . Further, other steps may illustrate the resizing of the size of the zones P1, P2, P3, also described above. - Although some embodiments of the various methods disclosed herein are described as comprising a certain number of method acts, further embodiments of a given method can comprise more or fewer method acts than are explicitly disclosed herein. In additional embodiments, method acts are performed in an order other than as disclosed herein. In some cases, two or more method acts can be combined into one method act. In some cases, one method act can be divided into two or more method acts.
- Having illustrated and described the principles of the disclosed technologies, it will be apparent to those skilled in the art that the disclosed embodiments can be modified in arrangement and detail without departing from such principles. In view of the many possible embodiments to which the principles of the disclosed technologies can be applied, it should be recognized that the illustrated embodiments are only examples of the technologies and should not be taken as limiting the scope of the invention.
