(1) Field of the Invention
The present invention relates to network communications and, more specifically, to providing high speed Internet access to users in hotel environments.
(2) Description of the Related Art
Any business traveler who relies on network communications to maintain contact with clients and the home office appreciates the availability of fast and reliable data ports at remote locations such as airport lounges and hotel rooms. The hospitality industry has only recently begun to understand the necessity of providing such high speed data connections to business travelers. In fact, given the explosive growth of network technologies and the corresponding dependence of the business professional on such technologies, hotels which do not move to provide high speed connectivity in guest rooms comparable to the typical office environment will likely lose a substantial portion of their business to hotels which do.
Unfortunately, many hotel rooms are not currently wired to accommodate high speed data traffic. That is, prior to 1990, virtually all hotel rooms were wired to provide only basic telephone service. As late as 1995, less than 10% of hotel rooms were wired to handle standard Ethernet data speeds. Even today, while the major players in the hospitality industry are searching for high speed connectivity solutions, the vast majority of hotel guest and conference rooms are still wired with low quality, single pair connections. One obvious solution would be to completely rewire all of the guest and conference rooms in each hotel facility to provide the desired data transmission capabilities. However, given the prohibitive cost of such an undertaking, a less costly solution would be desirable.
Even if such a costly rewiring were undertaken, there are other problems which are not addressed by an infrastructure upgrade. For example, even if a high speed connection to the hotel's host is provided, it will often be the case that a guest's laptop computer would be incompatible with the hotel network in some way. Thus, each guest's laptop must be configured appropriately in order to communicate with the network and with the Internet beyond. This would likely involve loading special software onto a guest's laptop each time the guest wants to go online. Not only would such a process be cumbersome and annoying to the hotel guest, it may also be unacceptable from the guest's point of view in that reconfiguring the laptop may interfere with the current configuration in undesirable ways.
Neither does a costly wiring upgrade address the administrative and security issues related to providing Internet access via a hotel host. That is, high speed Internet access for hotel guests requires a network at the hotel property and some sort of connection between the hotel network and the Internet, e.g., a T1 or T3 line. A firewall at each hotel property would also be required to protect the internal network from unauthorized access. The existence of the firewall at each property, in turn, requires that most of the control and administration of the local network be performed at the hotel property rather than remotely, thus representing an undesirable redundancy of administrative functions.
Another administrative difficulty related to maintaining each hotel property as a separate Internet host involves the management of IP addresses. Ranges of globally unique 32-bit IP addresses are issued to organizations by a central Internet authority. These addresses are organized in a four octet format. Class A IP addresses are issued to very large organizations and employ the first of the four octets to identify the organization's network and the other three to identify individual hosts on that network. Thus, a class A address pool contains nearly 17 million (224) globally unique IP addresses. With class B addresses, the first two octets are used to identify the network and the last two to identify the individual hosts resulting in 64,000 (216) globally unique IP addresses for each organization. Finally, with class C addresses, the first three octets are used to identify the network and the last octet to identify the individual hosts resulting in only 256 (28) globally unique IP addresses for each organization.
Unfortunately for many medium to large size organizations (1,000 to 10,000 hosts), it has become very difficult, if not impossible, to obtain anything other than a class C address for their networks due to the fact that the class A and B address spaces have been almost entirely locked up. This problem has been addressed to some extent by the use of a Network Address Translation (NAT) protocol. According to such a protocol, when a local host on an organization's network requests access to the Internet, it is assigned a temporary IP address from the pool of globally unique IP addresses available to the organization. The local host is identified by the globally unique address only when sending or receiving packets on the Internet. As soon as the local host disconnects from the Internet, the address is returned to the pool for use by any of the other hosts on the network. For additional details on the implementation of such a protocol please refer to K. Evegang and P. Francis, The IP Network Address Translator (NAT), Request for Comments “RFC” 1631, Cray Communications, NTT, May 1994, the entirety of which is incorporated herein by reference for all purposes.
Such dynamic assignment of IP addresses might be sufficient for certain organizations as long as the number of simultaneous users which require access to the Internet remains below the maximum of 256. However, if, for example, a 1200 room hotel were hosting an Internet technologies seminar it would be extremely likely that the demand for Internet access would exceed the available address pool. All of this also assumes that a major hotel chain would be able to obtain a complete class C pool of addresses for each of its properties; not necessarily a reasonable assumption.
It is therefore desirable to provide methods and apparatus by which each of the properties in a major hotel chain may provide high speed Internet access to each of its guest rooms in a secure, inexpensive, and reliable manner without undue administrative burdens on the individual properties.
According to the present invention, methods and apparatus are provided which make use of existing hotel wiring infrastructures to provide secure, high speed data and Internet access to each of the guest rooms in a hotel property. Specific implementations of the technology described herein have the ability to auto-baud down to whatever speed the wiring infrastructure will allow thus providing the maximum bandwidth allowable by that infrastructure. According to specific embodiments, the present invention is able to select the maximum baud rate appropriate for each individual guest room. According to other specific embodiments, where the wiring to the guest rooms is a single pair phone line, the present invention allows 1 Megabit half duplex data transmissions to coexist on the single pair with standard telephone signals.
According to one embodiment of the invention, each guest room in the hotel is interconnected via the hotel's current wiring infrastructure into a local network. When a guest wishes to access the Internet, he connects his laptop to an in-room module installed in each guest room which temporarily assigns a “fake” local IP address to the guest's laptop. The “fake” local IP address is associated with the in-room module and is unique on the hotel's local network. The address is “fake” in that it is not a valid Internet address and in that it replaces the laptop's own real IP address. The assigned local IP address uniquely identifies the guest's laptop on the hotel network while that laptop remains connected to the in-room module.
A headend module in the hotel handles packet routing and provides access to the Internet. In facilitating access to the Internet, the headend module temporarily assigns globally unique IP addresses from a pool of, for example, class C addresses to in-room modules in individual guest rooms in response to requests for Internet access from those rooms. An assigned IP address remains dedicated to a particular in-room module (and thus the associated guest's computer) for the duration of the Internet transaction. Upon termination of the transaction, the globally unique IP address is disassociated from the in-room module and put back into the pool for use in facilitating a later Internet transaction from any of the hotel's rooms.
According to another embodiment of the invention, the local networks of a number of hotels are interconnected via a remote server thereby forming a private wide area network, or a virtual private network. The operation of the virtual private network to provide high speed data and Internet access to individual guest rooms is similar to the process described above except that the “fake” IP address of the in-room modules are unique over the entire virtual private network, and the temporary assignment of globally unique IP addresses is performed by the remote server rather than the hotel headend. This is advantageous in that it is contemplated that the remote server has a larger pool of such addresses associated therewith than an individual hotel network might be able to procure (e.g., a class B address pool).
Thus, because the IP address needs of all of the hotels in the virtual private network are spread out over the entire installed base of the remote server, bursts of need at any one property which exceed the capacity of a single class C address pool may be accommodated. The virtual private network embodiment of the present invention also has the advantage that firewall security and other network administrative functions may be centralized and performed remotely without compromising the security of any individual hotel network.
Thus, according to the present invention, methods and apparatus are provided for providing access to a network via a first one of a plurality of network access nodes in the network. The network access nodes each have a network address associated therewith which is unique on the network, the first network access node having a first network address associated therewith. The first network address is associated with a first computer while the first computer is connected to the first network access node thereby providing access to the network.
According to a more specific embodiment, Internet access is provided to a first computer via a first one of a plurality of network access nodes in a network using a plurality of globally unique IP addresses. The network access nodes each have a network address associated therewith which is unique on the network, the first network access node having a first network address associated therewith. The first network address is associated with the first computer while the first computer is connected to the first network access node thereby providing access to the network. A first one of the globally unique IP addresses is associated with the first network address for conducting an Internet transaction. The first globally unique IP address is disassociated from the first network address upon termination of the Internet transaction. The first globally unique IP address is then available for association with any of the network addresses. According to one embodiment, the network comprises a local area network and the associating and disassociating of the globally unique IP address is done by a headend associated with the local area network. According to another embodiment, the network comprises a wide area network and the associating and disassociating of the globally unique IP address is done by a remote server which controls the wide area network.
According to a specific embodiment, a network is provided having a plurality of network access nodes each having a network address associated therewith which is unique on the network. Each network access node is for providing access to the network for a computer connected to the network access node. A headend module interconnects the network access nodes. The network address associated with each network access node is associated with the computer connected thereto thereby providing access to the network.
According to another specific embodiment, a wide area network is provided having a plurality of networks each comprising a plurality of network access nodes. Each network access node has a network address associated therewith which is unique among the plurality of networks. Each network access node provides access to the wide area network for a computer connected to the network access node. A remote server interconnects the plurality of networks into the wide area network. The network address associated with each network access node is associated with the computer connected thereto thereby providing access to the wide area network.
According to yet another specific embodiment, a network access node is provided for providing access to a network of which the network access node is a part. The network access node has a network address associated therewith which is unique on the network. According to a more specific embodiment, the network address node is operable to associate the network address with a computer while the computer is connected to the network access node thereby providing access to the network.
According to a further specific embodiment, a headend module is provided for interconnecting a plurality of network access nodes in a network. Each network access node has a network address associated therewith which is unique on the network and provides access to the network for a computer connected to the network access node. According to a more specific embodiment, the headend module associates the network address associated with each network access node with the computer connected thereto thereby providing access to the network.
According to another specific embodiment, methods and apparatus are provided for providing conference services over a network having a plurality of users associated therewith. A group identification tag is associated with selected ones of the plurality of users thereby identifying the selected users as attendees of the conference. The conference services are provided on the network. Access to the conference services is then restricted to the selected users using the group identification tag.
According to another specific embodiment, a method for providing Internet access to a computer via a first one of a plurality of network access nodes in a network using one or more globally unique IP addresses is disclosed. The method includes associating a first local IP address with the computer while the computer is connected to the first network access node thereby providing the computer with access to the network, wherein the first local IP address is one of a plurality of local IP addresses used on the network. The method further includes monitoring transmissions received from the first network access node to determine when the first computer requests an Internet transaction. The method further includes associating a first one of the globally unique IP addresses with the first local IP address thereby allowing the computer to conduct the Internet transaction, and disassociating the first globally unique IP address from the first local IP address after termination of the Internet transaction, the first globally unique IP address then being available for association with any of the local IP addresses used on the network.
According to another specific embodiment there is disclosed an apparatus for providing Internet access to a computer via a first one of a plurality of network access nodes in a network using one or more globally unique IP addresses. The apparatus includes a first communication interface coupled to the network, a second communication interface coupled to the Internet, one or more processors coupled to the first and second communication interfaces, and a memory device storing program instructions. When the program instructions are executed by the one or more processors, the instructions cause the one or more processors to associate a first local IP address with the computer while the computer is connected to the first network access node thereby providing the computer with access to the network, wherein the first local IP address is one of a plurality of local IP addresses used on the network, and monitor transmissions received from the first network access node to determine when the computer requests an Internet transaction. The instructions further cause the one or more processors to associate a first one of the globally unique IP addresses with the first local IP address thereby allowing the computer to conduct the Internet transaction; and disassociate the first globally unique IP address from the first local IP address after termination of the Internet transaction, the first globally unique IP address then being available for association with any of the local IP addresses used on the network.

A further understanding of the nature and advantages of the present invention may be realized by reference to the remaining portions of the specification and the drawings.
a and 3b are more detailed block diagrams of the in-room module and head-end module of
Transmission line 110 connects IRM 104 to the hotel's head-end 112 via any of a wide variety of infrastructures. In the example shown, transmission line 110 connects IRM 104 to head-end 112 via standard telephone company wiring as represented by punch down blocks 114 and 116 and telephone company transmission line 118. It will be understood, however, that the wiring between IRM 104 and head-end 112 may take other forms such as, for example, a four-conductor Ethernet network. Head-end 112 comprises punch down block 116 and public branch exchange (PBX) 120. Interposed between punch down block 116 and PBX 120 is a connection port 122 which, according to a specific embodiment, may be easily installed simply by unplugging the standard 24-pin connector from PBX 120, plugging connection port 122 into the PBX connector (not shown), and plugging the original connector from punch down block 116 into connection port 122. Standard telephone signals pass through connection port 122 to PBX 120 while half duplex Ethernet data packets are transmitted and received by head-end module (HEM) 124.
Depending on the configuration of the present invention, HEM 124 performs a variety of functions and, according to some embodiments, can be thought of as an enhanced router with additional capabilities programmed into its operating system. That is, according to such embodiments, HEM 124 serves as a switch which routes data packets to and from IRMs 104, and serves as the other end of the communications to and from IRMs 104 in which Ethernet data and phone signals are combined over single twisted pair technology.
According to other alternative embodiments, HEM 124 handles address translation and assignment, controls network access, and serves as a bridge for Ethernet data transmitted over the hotel's single twisted pair infrastructure. HEM 124 has a plurality of ports 126 each of which communicates with a corresponding IRM 104. This communication may be individually monitored and controlled (by either the IRM or the HEM) thus allowing central hotel management of billing and access as well as the ability to generate reports for troubleshooting purposes.
Each IRM 104 (and thus the corresponding HEM port 126) has a fixed IP address which may be configured using the Simple Network Management Protocol (SNMP). If the guest's computer connected to a particular IRM 104 does not have its own internal IP address, the fixed IP address of the corresponding IRM 104/HEM port 126 is assigned to the guest's computer using the Dynamic Host Configuration Protocol (DHCP) to facilitate access to network 100. If the guest's computer already has its own internal IP address, address translation is performed between the computer's internal IP address and the fixed IP address of the IRM 104/HEM port 126. According to various embodiment of the invention, this address translation may be performed by either IRM 104 or HEM 124. HEM 124 has a small boot ROM (not shown) for basic IP communications and a large flash ROM (not shown) for fully functional software and configuration data. This allows for remote software upgrades using, for example, an encrypted protocol riding on top of IP.
Where the transmission line connecting the IRM to the hotel network comprises a single twisted pair of conductors, the data communications between the IRM and the HEM are configured so that they may be transmitted substantially simultaneously over the single twisted pair with the standard telephone signals from the phone in the guest room (206). A specific technique by which this configuration is effected is described below with reference to
Once the connection is established, the communications between the IRM and the HEM are monitored either periodically or continuously for a variety of purposes (208). This information may be used by the hotel for billing purposes or for troubleshooting and improving the reliability of the hotel network.
If an Internet transaction is requested by the guest's computer, a globally unique IP address from a pool of such addresses is temporarily associated with the network IP address currently associated with the guest's computer using, for example, a network address translation protocol (210). As discussed above, the pool of addresses could be, for example, class A, B, or C addresses. As will be discussed below with reference to
a and 3b are more detailed block diagrams of IRM 104 and HEM 124 of
According to a specific embodiment, IRM 104 also includes transmission circuitry 308 for transmitting and receiving data on a single twisted pair of conductors of which the majority of hotel wiring infrastructures are comprised. According to one embodiment, a portion of transmission circuitry 308 is implemented according to the home PNA (Phone-line Networking Alliance) standard which allows half duplex data and phone signals on the same line as illustrated by the diagram of
According to a specific embodiment, transmission circuitry 308 is operable to associate the network IP address associated with IRM 104 with the guest's computer. That is, the address translation or assignment which allows the guest access to the local or wide area network is performed by the transmission circuitry in the IRM. According to a more specific embodiment, transmission circuitry 308 includes a processing unit 309 based on RISC microprocessor which performs the address translation, the combining and separation of signals for transmission to the headend, and the routing of the received signals to the appropriate IRM port. According to a specific embodiment, processing unit 309 comprises an Intel 80960VH and the appropriate support circuitry.
According to another specific embodiment, IRM 104 also includes control circuitry 310 for receiving control information via the hotel's network for controlling one or more control systems 311 proximate to the IRM. As will be discussed below with reference to
Transmission circuitry 308 (using processor 309) discriminates between the various data it receives and directs it to the appropriate port on IRM 104 according to address information in data packet headers. According to a specific embodiment, digital audio and video may be transmitted to individual rooms via the system described herein. The digital audio and video are directed to additional data port 307 to which an audio and/or video system may be connected for presenting the transmitted content. In this way, an ambience may be set for the guest's arrival. In addition, the guest could select a wide variety of entertainment and information services via the hotel network which may then be transmitted to the guest's room via the auxiliary data port 307 on IRM 104. According to one embodiment, data port 307 receives audio data which directly drives a pair of speakers in the guest room.
Specific embodiments of IRM 104 also include an LED or LCD display 316 on which status and other information may be communicated to the occupant of the guest room whether or not they are currently connected. For example, before a connection is made, display 316 could be used to inform the hotel guest of all of the services available through IRM 104 as well as instructions for connecting to IRM 104. Other information such as stock quotes and weather information may also be presented continuously or periodically. Once connected, display 316 could communicate the status of the connection as well as the time connected and current connection charges. It will be understood that a wide variety of other information may be presented via display 316.
IRM 104 may also include an array of individual colored LEDs 318 which provide information to the user. Such LEDs may indicate, for example, the connection status of the IRM, i.e., whether it is connected to the HEM, using red or green LEDs. LEDs 318 may also be configured to indicate a purchase status to the user. That is, because connection services are often purchased in 24 hour blocks, LEDs 318 may indicate to the user whether she is operating within a block of time which has already been paid for (green), whether the end of the current block is approaching (yellow), or whether she has already entered the next time block (red). LEDs 318 could also indicate which type of connection the user has established, e.g., USB, Ethernet, or IEEE 1394.
As mentioned above and as shown in
The interfaces 354 and 356 are typically provided as interface cards (sometimes referred to as “line cards”). Generally, they control the sending and receipt of data packets over the network and sometimes support other peripherals used with HEM 124. The low and medium speed interfaces 354 include a multiport communications interface 362, a serial communications interface 364, and a token ring interface 366. The high-speed interfaces 356 include an FDDI interface 368 and a multiport Ethernet interface 370. Preferably, each of these interfaces (low/medium and high-speed) includes (1) ports for communication with the appropriate media, (2) an independent processor, and in some instances (3) volatile RAM. The independent processors control such communications intensive tasks as packet switching, media control and management. By providing separate processors for the communications intensive tasks, this architecture permits the master microprocessor 352 to efficiently perform routing computations, network diagnostics, security functions, etc.
The low and medium speed interfaces 354 are coupled to the master CPU 352 through a data, control, and address bus 372. High-speed interfaces 356 are connected to the bus 372 through a fast data, control, and address bus 374 which is in turn connected to a bus controller 376.
Although the system shown in
Regardless of network device's configuration, it may employ one or more memories or memory modules (including memory 360) configured to store program instructions for the network operations and network access and control functions described herein. The program instructions may specify an operating system and one or more applications, for example. Such memory or memories may also be configured to store, for example, control information for controlling in-room control systems, etc.
Because such information and program instructions may be employed to implement the systems/methods described herein, the present invention relates to machine readable media that include program instructions, state information, etc. for performing various operations described herein. Examples of machine-readable media include, but are not limited to, magnetic media such as hard disks, floppy disks, and magnetic tape; optical media such as CD-ROM disks; magneto-optical media such as floptical disks; and hardware devices that are specially configured to store and perform program instructions, such as read-only memory devices (ROM) and random access memory (RAM). The invention may also be embodied in a carrier wave travelling over an appropriate medium such as airwaves, optical lines, electric lines, etc. Examples of program instructions include both machine code, such as produced by a compiler, and files containing higher level code that may be executed by the computer using an interpreter.
Referring back to
As described above, each HEM port 126 (and thus the corresponding IRM 104) has a fixed IP address which may be configured using SNMP. The fixed IP address of the HEM port 126 and the IRM 104 is assigned to the guest's computer using DHCP. Alternatively, an address translation is performed between the computer's internal IP address and the fixed IP address of IRM 104/HEM port 126. HEM 124 has a small boot ROM 378 for basic IP communications and a large flash ROM 380 for fully functional software and configuration data. This allows for remote software upgrades using, for example, an encrypted protocol riding on top of IP.
According to various embodiments, HEM 124 also comprises transmission circuitry 316 for transmitting and receiving data on a single twisted pair of conductors. Thus, the Ethernet data which has been combined with the standard telephone signals at IRM 104 may be picked off and reconfigured for transmission according to standard Ethernet techniques. Also, data headed to IRM 104 may be combined for transmission over the single twisted pair. As with transmission circuitry 308, transmission circuitry 316 may be implemented according to the home PNA standard.
The embodiment of
Having each hotel property directly connected to the Internet is problematic for effecting control of the hotels from a central location. That is, the more each hotel LAN is amenable to control from a central location, the more vulnerable it is to hacking With VPN 604, security is complete and centralized control is virtually unlimited. This makes things like remote software upgrades convenient thus eliminating what might otherwise be significant field service costs. In addition, because much of the equipment is centrally located, the costly redundancy of equipment and support functions at each hotel property made necessary by the embodiment of
Another important benefit of VPN 604 relates to the management of globally unique IP addresses. As mentioned above, there is a paucity of pools of globally unique IP addresses which are sufficiently large to accommodate each host on the networks of most medium to large size organizations. For example, one pool of class C addresses accommodates less than 256 simultaneous users on a network. This might be sufficient at most hotels much of the time, but it is clear that there are foreseeable circumstances where it would not be. For example, as mentioned above, if a 1200 room hotel hosted an Internet technologies seminar it is highly likely that such a pool of addresses would not be sufficient. In addition, this scenario makes the assumption that each property in a hotel chain (some comprising over 1000 properties) could procure a pool of class C addresses.
VPN 604 addresses this problem in that it spreads the IP address needs of each of the hotel properties over the resources of the entire wide area network. Thus, for example, a single class B pool of addresses might be used to accommodate all of the Internet access needs of an entire hotel chain even where the total number of rooms in the chain far exceeds the number of available globally unique IP addresses. That is, large bursts of IP address needs may occur simultaneously at dozens of the hotel properties without exhausting the nearly 64,000 globally unique addresses available in the class B pool.
Other secure services may also be provided via VPN 604. For example, video teleconferencing-over-IP 612 and voice-over-IP communications 614 may be provided to hotel guests. Moreover, by arranging access to VPN 604 by corporate hosts 616, individual employees of those corporations can have secure access to their employer's network from remote locations. Other services such as, for example, property management services 618 may be provided to the management of hotels 602.
When the guest checks in, the assigned room is then automatically configured to suit that guest's preferences.
One method of configuring the room automatically involves adjusting various controls in the room via remote control signals such as, for example, radio frequency (RF) or infrared signals. According to a specific embodiment of the invention, control signals are sent to the IRM (e.g., IRM 104 of
Referring now to
The in-room module then displays some of the received information, e.g., stock quotes, and converts some of the received information into an appropriate set of control signals, e.g., RF signals, for communicating with the rooms various environmental controls (906). These environmental controls may include, for example, the thermostat, lighting controls, stereo controls, television controls, etc. The appropriate adjustments are then made to the various systems in the guest room to provide the optimal environment specifically suited to the stated preferences of the arriving guest (908).
The system bus architecture of file server 1000 is represented by arrows 1020. However, these arrows are illustrative of any interconnection scheme serving to link the subsystems. For example, a local bus could be utilized to connect the central processor to the system memory. File server 1000 is but an example of a system suitable for use with the invention. Other architectures having different configurations of subsystems may also be utilized.
Various embodiments of the present invention may be used to provide special levels of service to specific groups such as, for example, the attendees of a conference at a hotel property. That is, conference attendees are identified when they connect to the hotel network and are provided access to specific content and online services which are related to the conference.
Conference services might include, for example, substantially real time voice communication and/or video teleconferencing with other attendees of the conference. Speakers or conference organizers may have software they want to distribute to attendees electronically. Only conference attendees have access to such electronic information. Conference specific content such as, for example, electronic copies of papers presented at the conference as well as PowerPoint® presentations are provided. Individual presenters at the conference can post follow up notes and answers to questions they were not able to get to during their presentation. Chat Rooms could be provided in which, at the end of the day, conference members can get online from their room to interact with other members. Only conference members would have access to the chat room. This service allows conference attendees to discuss questions and comments about the conference, talk about the sessions that were good and bad, critique speakers, and in general exchange information with other attendees. According to various embodiments, the chat rooms could be recorded and the information provided to conference organizers to allow them to better serve their members at future conferences. The real names of chat room participants may be excluded from this information. Bulletin boards for the posting of information by any conference attendee may also be provided. Discounted access to other services such as, for example, entertainment and information services, may also be provided.
As described above with reference to
If the network IP address associated with a particular guest's computer is associated with the group ID tag (1108), access to the conference specific services and content are provided to the user of that computer (1110). If, on the other hand, the network IP address is not associated with the group ID (1108), access to the conference specific services and content is blocked. The network IP address remains associated with the guest's computer until the session ends, e.g., the computer is disconnected from the IRM or powered down (1114).
The technique described above with reference to
While the invention has been particularly shown and described with reference to specific embodiments thereof, it will be understood by those skilled in the art that changes in the form and details of the disclosed embodiments may be made without departing from the spirit or scope of the invention. For example, many of the embodiments described herein have been described with reference to hotels. It will be understood, however, that the techniques employed by the present invention may be applied to a variety of structures and institutions such as, for example, schools, office buildings, and the like.
