  • DISCUSSION OF THE RELATED ART As is known, there are a variety of systems for monitoring patients in, for example, a hospital or other closely controlled personal care facility. Similar systems are known to be implemented in retirement communities, or other residential living communities where patient care and monitoring is more essential than it is in, for example, an apartment complex. In facilities such as these, it is important to provide a fast response to personal needs. For example, if a crippled or elderly person falls, often that person cannot get up under their own power. Instead, the person requires assistance from others under such situations.
  • a "call” button may be provided on the wall in a bathroom location, as well as one or two other locations within the person's living area. If the person falls, then the person must usually crawl to or otherwise reach the "calf button in order to request assistance. Obviously, if the person falls a relatively substantial distance away from the "call” button, reaching the button, in and of itself, may be a difficult task.
  • this system was intended for in-home personal use, and included a base unit that was interfaced to a telephone line.

  • the "Life Call” system also included an intercom that allowed the person, once a telephone connection was established, to verbally communicate from the person's remote transmitter to a remote location by way of the base unit.
  • a disadvantage of this type of system is that the system is limited in that if a patient travels too far from the base unit, then the remote transmitter becomes out of range and cannot access the base unit.

  • FIG. 1 is a block diagram illustrating certain fundamental components of a system 100 constructed in accordance with the teachings of the present invention. More particularly, a system 100 of the present invention includes a plurality of transmitters 102, 104, 106, and 108.
  • transmitters 102, 104, 106, and 108 are preferably RF (Radio Frequency) transmitters, that are relatively small in size and transmit a relatively low power RF signal.
  • RF Radio Frequency
  • the transmission range of a given transmitter 102, 104, 106, and 108 is relatively limited.
  • this relatively limited transmission range of the transmitters 102, 104, 106, and 108 is an advantageous and desirable characteristic of the system 100.
  • the transmitters 102, 104, 106, and 108 are depicted as including a keypad, in certain embodiments of the invention the transmitters may include only two or three buttons. In still further embodiments, the transmitters may not include any external buttons at all. Instead, the transmitters may be electrically integrated into another device, such as a smoke detector, a thermostat, a security system, etc. , where external buttons are not needed.
  • the system 100 also includes a plurality of repeaters 1 10, 112, and 1 14.
  • Each repeater 1 10, 112, and 114 is configured to receive an incoming RF transmission (transmitted by a transmitter) and to transmit an outgoing signal.
  • This outgoing signal may be a higher power RF transmission signal, or alternatively by an electrical signal over a conductive wire, fiber optic cable, or some other transmission medium.
  • the internal architecture of a transmitter 102 and a repeater 1 10 will be discussed in more detail in connection with FIGS. 3 and 4.
  • the repeaters 110, 112, and 114 may be stand alone devices. Alternatively, they may be integrated into an alarm device, such as a smoke detector, a security system, a thermostat, etc.
  • a computer 120 is disposed to receive communications from the various repeaters, 110, 112, and 1 14, analyze the transmissions so received, and carry out any appropriate operations.
  • the computer 120 may communicate information, service requests, etc. to remote locations 122 via a direct dial link over the PSTN, or via a TCP/IP connection across the Internet 130.
  • a system constructed in accordance with the teachings of the present invention may be used in a variety of environments.
  • a system such as that illustrated in FIG. 1 may be employed in a retirement community.
  • the system may be implemented in a manner to provide universal monitoring and control of residents, as well as systems within the community.
  • an RF transmitter 102 may be worn or carried by each resident within the community (see FIG. 2 A). If at any time the resident 103 is in need of medical assistance, the resident may signal for such assistance by simply pressing a button provided on the transmitter 102. In a manner that will be described below, this request for assistance may be communicated from the transmitter 102 to a nearby repeater 110.
  • the repeater 110 may then further communicate this information to a central computer 120. Since the transmitter unit 102 is wireless, it may be toted about without restriction or limitation. In addition, the transmitter 102 may be configured to communicate encoded information that identifies the transmission as being a request for assistance, as well as transmitting information that identifies the particular person in possession of the transmitter 102. The repeater 110 may receive and further communicate this information onto the computer 120. In addition, the repeater 1 10 may add a repeater identification number to the information it communicates. Accordingly, the computer 120 may evaluate the repeater identification number to ascertain the proximate location of the transmitter 102. This will assist personnel in rapidly locating the individual in need of assistance.
  • the computer 120 may summons the appropriate personnel to provide assistance, in any of a variety of manners.
  • One manner may be to alert one or more persons by way of a direct dial telephone connection across the PSTN 130, whereby a request for assistance may be communicated to a remote location by dialing a predetermined phone number.
  • the computer 120 may communicate this information to a remote location, or locations, via the Internet.
  • a server may be provided in connection with the computer 120 to maintain a constant connection to the Internet, so that a request issued there-across may be done so rapidly, without the delay associated with the normal start-up and connection. Alternatively, for intermittent requests, a constant connection need not be maintained to the Internet.
  • the computer 120 may communicate emergency request information to a centralized remote location.
  • a centralized location may be configured to receive such requests from a plurality of different retirement communities, or other locations.
  • a person at the centralized location may then contact the appropriate personnel at a given community (the community requesting assistance).
  • the community requesting assistance may eliminates the need for each individual community to employ a full- time person to monitor requests that come across the computer 120.
  • the computer 120 may be configured to issue a page to personnel in response to the request for assistance.
  • a vertically-integrated retirement community comprising a high-rise apartment building having many floors. There may be one or more staff individuals, at a given time, stationed on each floor. If the repeater 110, through which a request for assistance is transmitted, is located on, for example, the seventeenth floor, then the computer 120 may page a designated staff person (or office) located on the seventeenth floor, to relay the request for assistance.
  • This page may be by way of an intercom system, a remote paging unit (e.g., a personal pager), or otherwise.
  • the information transmitted with the page may include (as will be further described below) the identification and/or description of the person needing emergency assistance.
  • transmitter units may be electrically integrated into various equipment, as well as being toted by individuals.
  • a transmitter 104 similar to transmitter 102, may be integrated into a smoke detector (see FIG. 2B), in such a way that an alarm condition from the smoke detector 105 may initiate a transmission from the transmitter 104 in much the same way that the user 103 (FIG. 2A) could initiate a transmission from the transmitter 102 by depressing a button.
  • the transmitter 104 may transmit a transmitter identification number, as well as a transmitter code, to a nearby repeater 112.
  • the repeater 112 may then add to this transmission a repeater identification number, which conveys location information to the computer 120.
  • integrating a transmitter 104 into a smoke detector in this fashion allows smoke detectors to be readily installed in a variety of locations, without having to be pre-wired into a particular location. Furthermore, for smoke detectors that have been prewired with a power source, additional communication lines need not be prewired, as communications from the smoke detector may be communicated via RF to a nearby repeater 112. Upon receiving a transmission that the computer 120 identifies as being a smoke alarm, the computer may communicate a request to a remote facility, such as a nearby fire station, as well as alerting staff persons on the premises of the emergency situation, so that corrected action may be taken immediately. In yet another implementation, a wireless transmitter 106 may be integrated into a climate control system 105.
  • the transmitter 106 may be integrated into a thermostat 107 in such a way that it periodically transmits the settings of the thermostat, as well as the sensed temperature to the computer 120. This information may be sent and identified by a transmitter code indicating only routine information. If, however, the temperature controls on the thermostat are set to extreme temperatures, the transmitter code transmitted to the computer 120 may be different, so as to demand a higher priority of response.
  • a first transmitter code may be communicated for the temperature settings, and a different transmitter code may be communicated based upon temperature readings.
  • the computer 120 may, based upon the transmitted code, make the ultimate determination as to the priority to assess a given transmission. It will be appreciated that, particularly in retirement communities having elderly and perhaps infirmed people, that the thermostat settings may be inadvertently set to inappropriate levels. Utilizing the transmission capabilities of the present invention, such settings may be closely monitored so that the appropriate personnel may be summoned to rectify a problem, before the temperature reaches extreme levels. In the past, one alternative solution to this problem has simply been to limit the ability of persons within such a community to exercise independent control over thermostats within their room or living area.
  • a system in accordance with the present invention overcomes the shortcomings, while providing control and flexibility to the residents within the community.
  • a transmitter 108 may be integrated into a residential security system.
  • a transmitter may be integrated within a sensor, such as the type that may sense a window 109 (see FIG. 2D). Integrating a transmitter in this way, into either a window sensor, door sensor, a motion detector, or other security sensor, allows the system 100 of the present invention to provide more comprehensive information and monitoring capability.
  • a central monitoring location can be utilized to monitor any of a variety of emergency or other conditions that may arise, providing a more cost effective system implementation.
  • the wireless transmitter 108 allows for ready adaptation of a window, door, or other structure, without having to undertake the expense of routing security wiring throughout the structure to handle this task.
  • the various transmitters 102, 104, 106, and 108 may have substantially identical construction
  • a plurality of repeaters 1 10, 112, and 114 which may be identical, are disposed throughout a complex in such a way that adequate coverage in a complex or community is provided.
  • the repeaters, 110, 112, and 1 14 may be dispersed sufficient that only one repeater will pick up a transmission from a given transmitter (due in part to the low power transmission nature of each transmitter).
  • two, or even more, repeaters may pick up a single transmission.
  • the computer 120 may receive multiple requests from the same transmitter, but from different repeaters. The computer 120 may utilize this information to triangulate, or otherwise more particularly assess the location from which the transmission is originating.
  • repeaters 1 10,112, and 1 14 may be integrated into alarm devices like the smoke alarm 105 (of FIG. 2B), the thermostat 107 (of FIG. 2C) or the security system 109 (of FIG. 2D).
  • the advantage of integrating a repeater, as opposed to a transmitter, into an alarm device relates to the ability of the repeater to receive incoming information, as opposed to merely transmitting information.
  • the central computer 100 may communicate back to the repeaters.
  • the repeater may communicate thermostat settings and/or temperature readings to the central computer 100.
  • FIG. 3 A is a block diagram that illustrates certain functional components of a transmitter 102, of the type worn or carried by a person, in more detail.
  • Blocks 202, 204, and 206 represent physical buttons, which a user may actuate to cause the transmitter 102 to initiate different transmissions.
  • buttons 202, 204, and 206 include a "test" button 202, a "wake-up” button 204, and a panic or “emergency” button 206.
  • a "test" button 202, a "wake-up” button 204, and a panic or “emergency” button 206 may be electrically wired to an interface circuit 208 which is configured to receive electrical signals from the buttons 202, 204, and 206, and ultimately convey that information to a data formatter 210.
  • the interface circuit 208 may simply comprise an addressable port that may be read by the data formatter 210.
  • each of the signal lines extending between the buttons and the interface circuit 208 may be pulled up by individual pull up resistors (not shown). Depressing any of the individual buttons may ground the electrical signal line interconnecting the respective button and the interface circuit 208.
  • buttons 202, 204, and 206 may constantly read from the port defined by the interface circuit 208, and all bit positions should remain high at any given time, if no buttons are depressed.

For example, if the transmitter identification code indicates that the transmission is due in response to an alarm condition at a smoke alarm, the appropriate action may be to establish a dial up connection with a local fire department (step 412). In addition, if the system ascertained that the location of the smoke alarm (based upon the repeater identification number) was the seventh floor of a building structure, this information may also be communicated to the fire department, as this would inform them that trucks with extension ladders, buckets, or other access devices may be needed.
  • the corrective action may be to alert local law enforcement officers (step 441) and/or a private security service. If the transmitter identification number and transmitter code indicated that a person was requesting emergency assistance, then the corrective action may be to dial out to contact emergency personnel, or initiate a page for personnel on site to respond. Such a page or dial out may further include location information, so that persons responding to the distress signal would know the approximate location of the person in need of assistance.

After a certain time, for example, 10:00 a.m. (step 430), the system may access a memory storage area to determine all residents who have depressed their "wake-up" button since the previous day. This would then provide a listing of all people who have checked-in for the morning. This list may be compared against the database of all residents who have been assigned a transmitter 102 (step 432). The system may then evaluate whether all such residents have checked-in for the morning (step 434). If not, the system may print a report of all persons whom have not yet checked-in (step 430).
  • the system may print a report indicating that all persons have checked in for the morning (step 438). It will be appreciated that these reports may then be forwarded, either by fax, dial-up connection, Internet connection, or simply by printing out on a local printer, to a person for patient or resident verification. Specifically, in the event that a report prints indicating that certain persons have not checked-in for the day, then an onsite staff person may be paged or otherwise prompted to check on the well being of that particular person.
  • a more complex system may employ transmitters having two-way communication capability.
  • the transmitters conveying information codes in the manner described hereinabove, they may also be adapted to convey voice information. Therefore, when a person presses, for example, the emergency button on his/her transmitter, then medical personnel, staff members, or others may respond by communicating via two-way radio with that particular person.
  • each transmitter may be equipped with a microphone and a speaker that would allow the person to communication information such as their present emergency situation, their specific location, etc.
  • the transceiver identification number is not necessary to identify the location of the transmitter. Indeed, in implementations where the transmitter is stationarily integrated into an alarm or other system (i.e., the location of the transmitter does not change), then the computer could be configured to identify the transmitter location by the transmitter identification number alone. In will be appreciated that, in embodiments that do not utilize repeaters, the transmitters will be configured to transmit at a higher RF power level, in order to effectively communicate with the computer.
  • the transmitter units may include an internal transceiver, as opposed to merely a one-way transmitter. This would allow the communication of information from the computer (or other source) to the transmitter units.
  • totable/handheld transmitter units may include a number of buttons that control various functions. As discussed above, these buttons may include a "Wake-up” button, a “Test” button, and an "Emergency” button. Each of these buttons has a predetermined function. However, if a transceiver was incorporated into the transmitter units, then the central computer could effect a change in the functionality of these buttons, by communicating such information to the transmitter units. Of course, additional circuitry /logic would be incorporated into the transmitter units to monitor for such incoming transmissions.
