Description

METHOD AND DEVICE FOR LOCATING A POSITION
Technical Field
The present invention relates to a method and device for locating a position of the same device.
Brief Description of the Drawings
Fig. 1 is a schematic flow diagram of method of the present invention.
Background Information
Children, pets, bicycles and other valuable personal belongings are sometimes lost. People spend a substantial amount of time worrying about losing, or trying to find lost items and persons/animals. All positioning systems available are either cumbersome to use or too expensive to buy. There is a need for an inexpensive and reliable system to keep track of certain objects, and most important, that the user can track them him/herself.
The present invention provides a solution to the above described problem. More particularly, the method is for locating the position of a position device. The position device is in communication with a communication network that is in communication with a positioning Internet center that is in communication with a stationary PC or a mobile handheld device. The device sends out signals, making it possible to position the device, to the communication network that forwards the position signals to the positioning internet center that converts the positioning information signal to a map signal that can be retrieved by the user to continuously show the changing position of the position device in real time on internet, wap-sites or similar. Detailed Description
With reference to Fig. 1, the present invention is a sophisticated system 10 for determining the position of a positioning device 12 by using a mobile telephone network 14, such as GSM, or a global positioning system (GPS) 16. It should be noted that GSM and GPS are just two examples of positioning systems and that the present invention may be used on future network and positioning systems. For example, the position of the device 12 may be determined via triangulation system that is part of the network 1 . The network 14 may be particularly useful if the device 12 is, for example, inside a tunnel or below ground because GSM is less sensitive to blocking materials compared to the system 16. The system 16 may rely on the positions of several satellites.
One object of the invention is to extract the positioning features of the low-cost electronic components from a mobile telephone so that the position of the device 12 can be determined. In this way, it is possible for the user to determine the position of the device in real time through internet PC or other mobile device such as a WAP phone 41. This makes it easy to use and inexpensive to purchase the device 12.
The device 12 is a very small device that is easy to bring hide. The device 12 may be attached to objects, such as children, elderly, pets, vehicles, precious items, important or valuable personal belongings that need to be remotely tracked to prevent the object from getting lost. A trademark or a web address may be printed on the device 12. The device 12 may have a receiver 18 for receiving signals and a transmitter 20 for transmitting signals. The device 12 may be equipped with a clock or a text message window so that the carrier of the device 12 may receive simple commands and other text messages. The device 12 may be equipped with an on/off switch but that is not necessary. The system 10 may also be equipped with an alarm feature so that the center (30) may receive and forward a distress signal 48a, 48b to the computer 26 or the device 41 of the user. It may also be possible for the user of the device 12 to respond to easy commands such by responding that a command has been received. More- sophisticated versions of the device 12 may include camera--, microphone and telephone. The device 12 may also be equipped with a sound device so that the device 12 may be made to make a sound with a remote commando from, e.g., a personal computer 26. This makes it relatively easy to find the device 12 should it be misplaced or located in a hard to find place such as on the ground in a forest.
Preferably, the device 12 may continuously send out signals 22 that may be received by the network 14 or signals 24 that may be received by the system 16.
Preferably, the information flow is one way from the device 12 to the network 14 or the system 16. However, the system 10 may also facilitate a two-way communication between the device 12 and the network 14 or system 16 if so desired.
The device 12 is associated with a personal code that is unique for each device . The personal code is not known to the person before the device 12 is purchased. The personal code may be printed on a scratch card so that the user can only find out what the code is by scratching off a cover surface to reveal the code. As will be explained below, the personal code may be used to uniquely identify the location of the device 12 because the device has a unique serial or code number that may be linked to the personal code.
A web site address may be printed on the device 12 or on the pad. When the user of the web site or wap site would like to find out the location of the device 12, the user may go on-line with a personal computer 26 or a WAP/mobile Internet telephone device 41 such as by connecting to the Internet or a similar network. When the computer 26 or the device 41 is connected to the Internet, it may send a connect signal 28a, 28b to a positioning Internet center 30 by contacting the website that is printed on the scratch card, the box or the device 12. When the center 30 receives the signal 28, it asks the user of the computer 26 or the device 41 for the personal code by sending back a request signal 32a, 32b. For example, the user of the computer 26 responds by sending back a personal code signal 34a, 34b that includes the personal code that is associated with the device 12. The center 30 may also request the user of the computer 26 or device 41 to provide additional information such as name, address, club association and buying habits. In this way, the user communicates two- way with the center 30. When the center 30 receives the personal code, the center 30 first checks if the code is valid and if the personal code is stored in a database.
The user may personalize his/her personal code that is assigned to the device when purchased. If the personal code is unacceptable, the center 30 sends back a reject signal. If the personal code is acceptable, the center 30 matches the personal code with an identification number for the device 12. A request signal 36a, 36b is then sent to either the network 14 or the positioning system 16. The signal 36 may include a request for the position of the device 12. The signal 36 may also include other requests such as whether it is wet or hot at the location of the device 12. For example, the signals, 22, 24 that are continuously sent to the network 14 and system 16, respectively, may include information about the conditions at the location of the device such as the temperature, humidity, wind or any other condition. The device 12 may also send information about whether the device 12 is moving and whether it is light or dark at the location.
The network 14 or the system 16 receives the signal 36 and sends back a positioning information signal 38a, 38b to the center 30. The center 30 receives the signal 38 and then translates the positioning information so that the position of the device 12 may be displaced on a map such as by connecting to a map database connected to the center 30. The database does not have to be at the center and could be at a different place. The center 30 then sends back a map signal 40a, 40b back to the computer 26 or the device 41 so that the user may see the location of the device 12 on a map. If so desired, the user may even see how the device 12 is moving on the map in real time. This may be accomplished by instructing the network 14 or system 16 to send positioning signal 38 at regular intervals. The web site map program may be equipped with additional services such as alarm, name of streets, zoom, etc. It may also be able to warn the user that the battery or power source of the device 12 is running out or failing by, for example, sending an e-mail or SMS message.
The WAP phone device or a similar hand held device 41, may be used as an on-site locator to exactly locate the three-dimensional position of the device 12. By adding a compass or/and gyroscope unit 42 and a sound or visual indicator 44 to the device 41, it is possible to obtain directions and distance to the device 12 in a display 44 of the device 41. The unit 42 may also be equipped with signal transmitters and receivers. By crosschecking the positions of the device 12 and the device 41, the center 30 may send directions to the display 44 of the device 41. For example, the display 44 may show arrows to indicate which way the user of the device 41 should go and the distance to the device 12 thus making it possible to pinpoint the location of the device 12 down to a few centimeters. For example, if the device 12 is located in a high rise building, the compass may be used to determine the exact two dimensional position of the position device 12 and the distance gauge 42 may show the three dimensional position by determine if the user is getting closer to the device 12 or not. In this way, the arrow is pointing in the direction of the position device 12.
The device 12 could also send a signal directly to the device 41 to show distance and directions between them and vice versa. It may also be possible to locate the device 12 by adding sound and light functions of the device. The sound and light functions on the device 12 may be activated directly by the user from the device 26 or 41.
An important feature of the present invention is that the user of the personal computer 26 or 41 may determine the location of the device 12 and that the initiation of the position request is generated by the computer 26 or 41 via the web site of the center 30.
While the present invention has been described in accordance with preferred compositions and embodiments, it is to be understood that certain substitutions and alterations may be made thereto without departing from the spirit and scope of the following claims .
