Description

 Parking lot access control system and method thereof  

The present invention relates to a traffic control system and method thereof, and more particularly to a parking lot traffic control system and method therefor.

As the Internet deepens into everyone's life, it is also easy to share things, from car, housing to office space. This phenomenon is also called the sharing economy. Due to the growth of the sharing economy, many people will release the idle space and open it to those who do not belong to the building, parking lot, etc., and then receive feedback such as rent, but in order to ensure the rights of both the renter and the user, the traffic control The design has also become more and more important.

In the prior art, there are various systems and methods for collecting space information available for sharing, establishing a matching platform between a taxi user and a user of a rented parking space, and sharing space such as parking spaces. For security and calculation of time, cost and other information considerations, users usually only get permission for one-time vehicles to enter and exit the building parking lot. Therefore, it is impossible to drive vehicles in and out of the parking lot multiple times during the appointment period, even because they cannot use the building. The personnel-only access channel must be accessed by the lane, causing great inconvenience to the user and safety concerns.

For example, a user chooses to temporarily rent an underground parking lot of an office building for two hours, obtains permission to enter the parking lot of the building, and drives through the lane to smoothly enter and park. In general, the office building has an elevator or stairs leading upstairs in the underground parking lot. It usually has access control. However, when the user rents a parking space, he only has permission to enter and exit the parking lot. Therefore, it is not possible to pass to the elevator or stairs dedicated to the personnel in the building. At this time, if the parking lot is not specially designed for the personnel-specific walkway next to the driveway, the user can only risk his life to walk up the driveway. In addition, if during the period of use reserved by the user, there is a temporary need to temporarily drive the vehicle out and then enter, in the prior art, only one-time access permit can be obtained when renting the parking lot, if the vehicle is driven during the reserved time period After you leave, you can't enter the game again. You can only give up the remaining appointment time and pay the same fee as the original appointment time. More likely, you can't go back to park your car. You must face the dilemma of not finding a parking space again. Overall, This design is very inelastic to the user and causes time and money troubles.

In view of the above problems, an object of the present invention is to provide a parking lot traffic control system and method thereof, which provide requestable traffic data that can be used multiple times, and record the user's entry and exit status, so as to achieve the effect of personnel entering and exiting control and improving safety.

Generally, the number of traffic control devices 100 may depend on the number of lane entrances and exits in the building. For example, one entrance and exit on the east side and one entrance and exit on the west side, one traffic control device 100 may be separately provided, or multiple accesses may be provided at a single entrance or exit. Control device 100. In addition, when one access control device 100 is provided for one entrance and exit, but a plurality of restriction access units 110 are provided corresponding to the same management unit 120, a sensor may be additionally provided next to each restriction access unit 110 to help identify the user or the most When the access restriction unit 110 is closed, for example, when there is two lanes in a single exit, the approaching lane may be provided with a restricted passage unit 110, and the exit lane may be provided with another restriction passage unit 110, and may be detected by the sensor. It is determined which lane has the car approaching the traffic control device 100 to confirm which restriction access unit 110 the management unit 120 is to open or close.

Referring to FIG. 1 again, in the embodiment, the private building has an entrance and exit and only one traffic control device 100 is provided. The traffic control device 100 has a restricted access unit 110 and a management unit 120 as an example to control the vehicle. C or personnel in and out. Among them, the vehicle C may be a diesel engine, a gasoline engine, a nuclear engine, or an electric engine as a push truck, a truck, a bus, a car, a locomotive, or a bicycle. Here, a car is taken as an example. Referring to FIG. 2A, FIG. 2B and FIG. 2C simultaneously, the restriction passage unit may be a roll door 110a (FIG. 2A) or a fence 110b (FIG. 2B) or an electric door 110c or an elevator door 110d (for an electric person). FIG. 2C) can also be a sliding door, a revolving door, a visible light beam, an invisible light beam, etc., regardless of whether there is volume or whether it is visible, as long as it has the function of restricting traffic or detecting traffic, it is applicable to the present invention. The access unit 110 is limited.

The management unit 120 is adjacent to the restricted access unit 110 and can be coupled by wire or wireless. The management unit 120 includes a communication module 121 for transmitting and receiving signals from the mobile communication device 400 and the server 500.

The first transceiver 200 and the second transceiver 300 respectively transmit the first signal D1 and the second signal D2, and the first transceiver 200 and the second transceiver 300 can both be located at the restricted access device 100 as a boundary between the inside and outside of the parking lot. The same side of the unit 110 (for example, both in the parking lot or outside the parking lot) may also be located on both sides of the restricted access unit 110 of the traffic control device 100 (as shown in FIG. 1 , the first transceiver 200 is disposed outside the parking lot and The second transceiver 300 is disposed in the parking lot). In addition, the first transceiver 200 or the second transceiver 300 may be disposed in the traffic control device 100 such that the traffic control device 100 includes the first transceiver 200 or the second transceiver 300 and will not be included in the pass. The first transceiver 200 or the second transceiver 300 of the control device 100 may be disposed at any position. For example, if the traffic control device 100 includes the first transceiver 200, the second transceiver 300 is placed in the traffic control device 100. The restricted access unit 110 is either inside the demarcated parking lot or outside the parking lot. As shown in FIG. 2A, the first transceiver 200 is disposed on the traffic control device 100, for example, integrated with the communication module 121 in the management unit 120, and the signal transmission and reception of the management unit 120 can be via the communication module 121; 2B, the first transceiver 200 and the second transceiver 300 are disposed in the parking lot, but respectively located on different sides of the restricted access unit 110b; and FIG. 2C is to set the first transceiver 200 and the second transceiver 300 to The elevator stairwell, which is connected to the car park and leads to the building, is known to be accessible to persons carrying mobile communication devices. The first transceiver 200 and the second transceiver 300 are configured to enable the mobile communication device 400 to change according to the signal strength of the first transceiver 200 and the second transceiver 300 when the mobile communication device 400 moves with the vehicle C or the person. The relationship is used to determine whether the state of the mobile communication device 400 is in the state of being out of the parking lot (exit) or entering the parking lot (admission). The first transceiver 200 and the second transceiver 300 need to be separated from each other by a horizontal distance in the direction of entry and exit. The exact placement position and the order of the first transceiver 200 and the second transceiver 300 do not affect the present. According to the invention, as long as the two signal transceivers allow the mobile communication device 400 to change the strength of the signals according to the two, the traffic state can be determined.

In addition, the first transceiver 200 and the second transceiver 300 can respectively be connected by a short-range communication module, such as a Bluetooth module, a wireless communication module (Wifi), and a beacon module (Beacon). , a Near Field Communication (NFC) module, a Radio Frequency Identification (RFID) module, etc., or a wireless communication module such as 3G/4G or a wired communication module. The group is applicable to the present invention as long as the signal strength of the first signal D1 and the second signal D2 can vary with distance, and is not limited thereto.

Referring to FIG. 1 again, in the embodiment, the mobile communication device 400 can be a portable device with a communication function such as a mobile phone or a tablet computer. When the user holding the mobile communication device 400 wants to pay for rent or borrow the parking lot for free, the mobile communication device 400 is operated to select and input the parking lot to complete the reservation parking procedure. After the reservation is completed, when the user drives the vehicle C to the parking lot, the mobile communication device 400 can be operated to request the server 500 to open the traffic control device 100 to enter the parking lot. The opening of the traffic control device 100 represents the opening of the restricted access unit 110 in the traffic control device 100. Since the mobile communication device 400 moves with the user, during the process of entering the parking lot, when the mobile communication device 400 on the vehicle C receives the first signal D1 and the second signal D2, it may be due to the mobile communication device 400. Moving, the signals of the first signal D1 and the second signal D2 will change with the change of the distance between the mobile communication device 400 and the first transceiver 200 and the second transceiver 300. According to the change of the strength and weakness, it can be judged that the traffic state of one of the mobile communication devices 400 is an exit state or an approach state, and the flow method of the judgment is described in detail later.

The server 500 can have a database for storing all parking lots and parking space information associated with the server 500. The distance between the server 500 and the traffic control device 100 is not limited, and the server 500 can be disposed in the traffic control device. Near 100, or set at the far end. The database of the server 500 may be disposed at the same location as the server 500, or may be disposed at another remote end, as long as the server 500 can read. When the user wants to stop and find a parking space, the mobile communication device 400 can be used to open a parking space sharing interface. The interface can be a webpage or an application stored in the mobile communication device 400, and the webpage or application can go to the server 500. Reading the data to display information of several parking lots and corresponding parking lots on the display of the mobile communication device 400. The parking lot information may include the address, the corresponding landmark, whether there are multiple entrances and exits (if any), The user's choice is provided by the fee, the available time, and the like. In the interface of the mobile communication device 400, the user can select a parking space to be rented or borrowed, and an entrance and exit of the parking lot to which the parking space belongs, and the entrance and exit will correspond to a traffic control device. After the user selects, he can input the basic information of the user, the contact method, the scheduled time period, etc., or log in with the account that has already completed the registration to complete the reservation process of the parking space. The server 500 is stored or written in the server 500 according to the traffic status (the appearance state or the approach state) reported by the mobile communication device 400, for example, stored or written in one of the memories in the server 500. Wherein, at the end of the predetermined time period, regardless of the current traffic state stored or written by the server 500 according to the traffic state reported by the mobile communication device 400, the server 500 stores or writes the traffic state of the mobile communication device 400 as "Appearance status" to facilitate other users to rent or borrow this parking space, or to allow the system to enter the refund settlement process.

The parking lot traffic control method of the present invention can be used in conjunction with the parking lot traffic control system of the present invention, and will be described below using a traffic control method in conjunction with a traffic control system. Please refer to FIG. 3, FIG. 4A and FIG. 4B. FIG. 3 is a flow chart of steps of a traffic control method according to a preferred embodiment of the present invention. FIG. 4A is a schematic diagram of a system connection relationship according to a preferred embodiment of the present invention, and FIG. Another schematic diagram of the system connection relationship in the preferred embodiment of the present invention.

Referring to FIG. 3, the traffic control method according to the preferred embodiment of the present invention includes the following steps: a first transceiver sends a first signal (S02); and a second transceiver sends a second signal (S04); The mobile communication device sends a request for access data a plurality of times during a predetermined period of time to respectively request a server to open a traffic control device (S06); the mobile communication device receives the first signal and the second signal, and according to the The strength of the signal and the second signal are changed to determine whether the state of the mobile communication device is an outgoing state or an approach state (S08); and at the end of the predetermined time period, the server stores the state of the mobile communication device It is the appearance state (S10).

Referring to FIG. 1 and FIG. 3 simultaneously, in step S02 and step S04, the first transceiver 200 transmits the first signal D1 in a broadcast manner, and the second transceiver 300 transmits the second signal D2 in a broadcast manner, and the first transceiver Preferably, the second transceiver 300 and the second transceiver 300 use the Bluetooth module of the short-range communication module to broadcast the first signal D1 and the second signal D2, so that the first signal D1 and the second signal D2 have a closer distance. The range of transmission, its signal coverage, can be the entire parking lot and the lane that enters the parking lot, or the area that the vehicle will pass when entering or leaving the parking lot (such as the main entrance and exit and the main walking lane). When the mobile communication device 400 moves within the signal coverage range, it can be determined that the signal strength of the first signal D1 and the second signal D2 changes. The first signal D1 and the second signal D2 may be any band of wireless electromagnetic signals (RF signals) such as infrared rays, long waves or short waves, and are applicable to the present invention as long as the signals can be transmitted wirelessly. It should be noted that step S02 and step S04 may occur simultaneously, or sequentially in any order, without affecting the implementation of the present invention.

In this embodiment, as shown in FIG. 3 and FIG. 7 , the parking lot control method of the present invention may further include: the server selects an input according to one of the mobile communication devices, and sends the request traffic information to the mobile communication device (S05). . In step S05, when the parking space is to be rented or borrowed, the user can start the parking space sharing interface on the mobile communication device 400, and the parking space sharing interface displays the information on the mobile communication device 400 according to the information provided by the server 500. There are parking spaces for parking spaces and information about the corresponding parking lots, such as the address, corresponding landmarks, whether there are multiple entrances and exits (if any), fees, and available time. The user only needs to make a selection input on the parking lot to be rented or borrowed on the parking space sharing interface displayed by the mobile communication device 400, so as to select a favorite parking lot and its entrance or exit or lane from the plurality of parking spaces, and Entering the user account and the time period to be reserved (including an estimated arrival time and an estimated time of departure), and the selected parking lot has a corresponding traffic control device 100, that is, the user is actually selecting One of the plurality of traffic control devices 100. 4A and 4B, the mobile communication device 400 allows the user to make a selection input, request the server 500 to make a reservation for the parking space, and the server 500 receives the request of the mobile communication device 400, and then performs the user identity or After the verification of the account, the confirmation request message D3 is sent to the mobile communication device 400 for subsequent activation of the traffic control device 100 as the mobile communication device 400. When the mobile communication device 400 obtains the request for the traffic data D3, the parking space reservation operation is completed. The server 500 stores the traffic control device 100 that requests the traffic data D3 to pass, so as to be able to discriminate which traffic control device 100 corresponds to when the mobile communication device 400 subsequently receives the request to turn on the traffic control device 100. The difference between FIG. 4A and FIG. 4B is that the first transceiver 200 is disposed outside the traffic control device 100 in FIG. 4A; and the first transceiver 200 in FIG. 4B is disposed in the traffic control device 100 and located in the management unit. In the communication module 121 in 120.

Referring to FIG. 4A, FIG. 4B and FIG. 5 simultaneously, after completing the reserved parking space, the mobile communication device 400 can receive a virtual ticket 510 from the server 500 and display it on the display surface of the mobile communication device 400. The virtual ticket 510 may include a plurality of icons with different functions, and each icon may represent an instruction. In this embodiment, the virtual ticket 510 has a request for access icon 511 as an example. The request pass icon 511 corresponds to the request pass data D3, is in an unactivated status before the start of the predetermined time period, and is in an activated state only when the predetermined time period starts, and is in the activated state after the user is enabled. The request pass icon 511 can send a corresponding request command, which is a request pass instruction. When the request pass icon 511 is enabled, its color gradation on the virtual ticket volume may become different, for example, the color scale is dark when originally not enabled, the color scale is bright when enabled, or the pass icon is requested. When 511 is enabled, a blinking state may be presented to prompt the user to request that the access icon 511 is already enabled.

Referring to FIG. 1 and FIG. 3 again, in step S06, when the predetermined time period begins, the user can drive the vehicle C and issue the request traffic data D3 to request the server 500 to open the corresponding traffic control device 100. The traffic control device 100, the first transceiver 200, and the second transceiver 300 can communicate with the mobile communication device 400 and the server 500. The communication protocol is not limited to wireless communication technology or wired communication technology. Therefore, when requesting to open the traffic control device 100, the mobile communication device 400 can directly send the request traffic data D3 to the server 500, and when the server 500 confirms that the user identity is correct, the traffic control device 100 can be commanded to be turned on; When the 3G/4G signal of the venue is not good, the mobile communication device 400 can also send the request traffic data D3 to the traffic control device 100, the first transceiver 200 or the second transceiver 300 by using the short-distance communication module. (Seeing who's signal status is better), and then receiving the communication module, the first transceiver 200 or the second transceiver 300 of the traffic control device 100 requesting the traffic data D3, and then forwarding the request traffic data D3 to the server 500, The command is passed to the access control device 100.

In an embodiment, when the mobile communication device 400 first requests the traffic data D3, the server 500 may not return the mobile communication device 400, and directly defaults the traffic state of the mobile communication device 400 to an incoming state. And start calculating parking time. The predetermined time period includes an approach time and an exit time, and may have a buffer time. The user's approach time or exit time may be calculated by the mobile communication device 400 by requesting the access data D3 to turn on the corresponding traffic control device 100. Please also refer to Figure 8. For example, if the scheduled time period is 15:00~17:00 (2 hours), the first request will be sent when the user enters the scheduled time for more than 5 minutes (15:05). Data D3, in order to request to enter the parking lot, in this case, the system allows the user to postpone the original scheduled playing time for 5 minutes, that is, 17:05. However, if the user has not entered the game later than the buffer time (for example, 15 minutes), the flexible offer method can be cancelled, and the time and cost are calculated by using the original scheduled entry time as the start time. The user can hold the mobile communication device 400 to request the traffic data D3 or use the traffic icon on the virtual ticket to enter and exit the parking lot multiple times within a predetermined time period, and request the traffic data D3 to open any restriction access unit 110 in the system. The restricted passage unit 110 may be disposed on a lane of the parking lot entrance or exit or an entrance or exit of the elevator or stairs that is connected to the parking lot and used for personnel. Of course, the server 500 can also have different request traffic data D3 corresponding to each entrance and exit of the parking lot, which is not limited by the present invention. In Figure 8, the user enters the parking lot at 15:05 three times (15:05, 15:10, 16:20) and three times to leave the parking lot (15:10, 16:00, 16:30) as an example.

As shown in FIG. 1 and FIG. 3, in step S08, when the user enters the parking lot by holding the mobile communication device 400 in the vehicle C, the user passes through the first transceiver 200 and the second transceiver 300, so that the user receives the first A signal D1 and a second signal D2, the mobile communication device 400 can determine whether the mobile communication device 400 is in an approach state or an exit state according to the strength of the two signals. In an embodiment, the first transceiver 200 and the second transceiver 300 are respectively disposed on two sides of the restriction passage unit 110, the first transceiver 200 is disposed outside the parking lot adjacent to the restriction passage unit 110, and the second transceiver 300 is disposed. It is disposed inside the parking lot next to the restricted access unit 110. Therefore, when the user enters the field, after passing through the first transceiver 200 on the outside, the user will gradually move away from the first transceiver 200 and approach the restricted access unit 110 and the second transceiver 300. At this time, the first communication signal D1 sent by the first transceiver 200 will gradually become weaker with the distance, and the second signal D2 sent by the second transceiver 300 will gradually become stronger. The signal change will continue until the location where the second transceiver 300 is located in the parking lot. At this time, the mobile communication device 400 can judge that its own traffic state is an approach state; when the user holds the mobile communication device 400, instead, it passes through the inner second transceiver 300 and gradually moves away from the second. The transceiver 300 approaches the restricted access unit 110 and the first transceiver 200. At this time, the second communication signal D2 sent by the second transceiver 300 is gradually weakened by the mobile communication device 400, and is received by the first transceiver. The first signal D1 sent by the device 200 will gradually become stronger, and the signal change will continue until the location where the first transceiver 200 is located outside the parking lot. At this time, the mobile communication device 400 can judge that the traffic state is an outgoing state. .

In another embodiment, the first transceiver 200 and the second transceiver 300 can also be disposed in the parking lot or outside the parking lot, or include one of the transceivers in the communication module 121 of the traffic control device 100, regardless of two. The method of setting the transceiver, the relative position, the judgment of the approach state and the appearance state are all the same method, as long as the user holding the mobile communication device 400 must pass through two transceivers when entering and exiting, and in the action When the communication device 400 is located between the two transceivers, the relative position change causes a signal strength change relationship, and the present invention can be realized by judging the approach state and the exit state.

In addition, the present invention only sets two signal transceivers as the basis for the signal change to judge the approach state and the exit state. If it is further known that the vehicle or the personnel enters and exits, another sensor must be added, and the sensor can be It is an infrared sensor or an image sensor, etc., which can be disposed in a parking space, a traffic control device 100, or a path through which other people or vehicles pass, for example, when the mobile communication device 400 determines that there is an appearance state, and uses the sensing. When the vehicle is found to be in the parking lot, it can be judged as a person's appearance; if the sensor senses that the vehicle is no longer in the parking lot, it can be judged as the appearance of the vehicle, and thus can be more accurately Control personnel and vehicles in and out.

Referring to FIG. 6A to FIG. 6D and FIG. 7 , in the embodiment, the parking lot control method of the present invention may further include: the mobile communication device sends a traffic status for the server to record (step S09). In step S09, after receiving the signal of the first signal D1 and the second signal D2, the mobile communication device 400 determines that the mobile communication device 400 is in the approach state or the exit state according to the change of its strength and weakness, and the mobile communication device 400 directly passes the state. It is sent to the server 500 for recording (Fig. 6A). In addition, when the network signal of the underground parking lot is not good, as shown in FIG. 6B, FIG. 6C and FIG. 6D, the short-distance communication mode may be selected, similar to the transmission manner of the requesting traffic data D3, and the mobile communication device 400 is similar. The traffic state is first sent to the nearest or better signal traffic control device 100 (as shown in FIG. 6B), the first transceiver 200 (FIG. 6C) or the second transceiver 300 (FIG. 6D). The traffic control device 100, the second transceiver 300, or the first transceiver 200 transmits a traffic status to the server 500 for writing and recording. The signal coupling between the first transceiver 200 and the second transceiver 300 or between the traffic control device 100 is preferably performed by using a long-distance low-power wireless transmission technology (LoRa). For example, when the device closest to the mobile communication device 400 is the first transceiver 200, but the second transceiver 300 is connected to the server 500, the traffic state is first sent by the mobile communication device 300. A transceiver 200, the first transceiver 200 is further transmitted to the second transceiver 300 by LoRa technology, and finally transmitted to the server 500 by the second transceiver 300. In addition, the mobile communication device 400 can also directly transmit the strength change received by the first signal D1 and the second signal D2 to the server 500 through the traffic control device 100, the first transceiver 200, or the second transceiver 300. The server 500 determines and records the traffic state of the mobile communication device 400. The determination of the approach state or the exit state is performed by which device does not affect the implementation of the present invention, as long as the server 500 is finally informed and recorded.

It should be noted that the request request traffic data D3 of step S06 may be repeated, and the time of occurrence may occur before, after or at the same time as step S08 and step S09, that is, requesting the transmission of the traffic data D3 and the state of the traffic. The judgment and the transmission may be transmitted simultaneously or sequentially, and even the traffic state is embedded in the request traffic data D3, and the above embodiments are all aspects of the present invention. Through the judgment of the state of the traffic, the system or the management of the parking lot can instantly understand the entry and exit of the vehicle, and help to control the entry and exit of the people in the parking lot, thereby achieving the effect of improving the safety of the parking lot.

Referring to FIG. 7 and FIG. 8 again, in step S10, at the end of the predetermined time period, or after a buffering time, the server 500 stores the traffic state of the mobile communication device 400 as an appearance state. Prior to this, whether the vehicle C or the simple person passes, whether passing through the lane or the elevator, the user can repeatedly enter and exit the parking lot by the request traffic data 300 in the mobile communication device 400, and in the server 500. Leave a record of the entry or exit status. However, when the predetermined time period ends, that is, the scheduled exit time arrives, the server 500 automatically stores the traffic state of the mobile communication device 400 as an appearance state, and the storage method may be to change the traffic state to the appearance state regardless of the last traffic state, or Also write and record an exit status. For example, after the first approach, the server 500 will record the traffic status code as "1" (to correspond to the approach state); then in the intermediate state transition state, the server 500 can only record "2" (in Corresponding to the transition state before the exit, or the server 500 can directly record the traffic status determined by the mobile communication device 400; finally, at the end of the predetermined time period, the server 500 directly stores or writes "3" (to correspond to the reservation). The time period ends). If the last state of the mobile communication device 400 in the predetermined time period is an approach state, it means that the user does not drive the vehicle C out within a predetermined time, and the server 500 sets the user's mobile communication device 400. After the traffic state is stored as the appearance state, since the user's vehicle is still in the parking lot, and the request for the traffic data D3 has expired and cannot be used, the server 500 will not allow the user to pass, so the user needs to apply for or re-purchase (re Selecting the input) or scheduling the number of parking hours to turn on the traffic control device 100 again to drive the vehicle out, so the system will know the user's delayed behavior and perform corresponding actions. If other users have reserved the parking space in the future, the system can also notify the management to find the towing vehicle for the towing operation.

In another embodiment, if the last state of the mobile communication device 400 in the predetermined time is an exit state, the time when the server 500 determines the appearance state is the user's mobile communication device 400 playing time, according to the mobile communication. The exit time of the device 400 can be compared to the estimated exit time, and a refund step can be performed. For example, as shown in FIG. 8, the user's original scheduled time period is 15:00~17:00, and at the end of the predetermined time period, that is, 17:00, the server 500 finds that the last transit state of the mobile communication device 400 occurs at 16 :00 is the appearance state, which means that the mobile communication device 400 is scheduled to be booked one hour in advance. If the parking lot is a paid parking lot and the one-hour fee is NT$40, the server can refund the full amount of 40 yuan or a certain amount. The proportion is refunded to the user.

In summary, the present invention provides a parking lot traffic control system and method thereof. The mobile communication device enters and exits the parking lot multiple times according to the requested traffic data, and determines the traffic state by receiving the strength change of the first signal and the second signal. The appearance state or an approach state is sent to the server for storage to achieve the effect of personnel control and safety improvement.

The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the invention are intended to be included in the scope of the appended claims.
