The ground monitoring units 20, 22, 24, 26 can accept incoming messages and relay outgoing messages from or to the satellite system 13. Depending upon whether the situation is emergency or non-emergency, a message is sent first to the police ground monitoring units 20. In an emergency, the police may be notified before the family, legal guardians, emergency contacts, etc. In a non-emergency, the signal can be first sent to the person's home, etc.
The local authorities can transmit a signal from the ground monitoring units 20, 22, 24, 26 to the satellite system 13 to communicate with the individual “Goldfish” watch 1. The satellite system 13 can directly set off or force the “Goldfish” watch 1 to obtain the location of a person wearing the personal “Goldfish” watch 1. The police departments can utilize the satellite system 13 to call the “Goldfish” watch 1 and locate a missing, trapped, or injured person.
Each “Goldfish” watch 1 may have a memory unit 56 that stores information regarding residence, medical information, and any other helpful information in an emergency situation. The satellite system 13 registers each user's personal code and stores the information in its secure network in the appropriate ground monitoring unit 20, 22, 24, 26 for easy identification of a “Goldfish” user.
In one embodiment, the personal locator system uses a portable transmitter-receiver 1 that communicates with the satellite communication system 13 which in turn communicates with a ground monitoring unit 20, 22, 24, 26. The portable transmitter-receiver 1 includes a computing device 63 that interacts with the satellite communication system 13 to determine the position of the user of the portable transmitter-receiver 1. The computing device 63 also functions to send or broadcast the determined position to at least the satellite communication system 13, and can also broadcast the determined position via antenna 5 to search and rescue transmitter-receivers 40. Other functions of the computing device include providing voice and data communication with at least the satellite communication system 13 and broadcasting, on demand, a distress signal. Additional, the computing device 63 can be initiated or triggered by a ground monitoring unit 20, 22, 24, 26 to determine the position of the user and broadcast the determined position back to the ground monitoring unit or to search and rescue transmitter-receivers 40.
Police Search and Rescue Units 40
In one embodiment, the police can use the communications system in search and rescue operations. The “Goldfish” watch 1 can have a transmitter preferably in the form of an antenna 5 that transmits a signal over ground communication technology such as wireless, cell phone, radio frequency, etc. The antenna 5 can transmit a signal that is capable of being received by local transmitter/receiver units 40.
Rescue animals 80 wearing portable, local receiver/transmitter units 40, such as a collar 81 (see FIG. 4) or vest, and police with local receiver/transmitter units 40 can find people in emergency and disaster situations preferably through the signal broadcast by the antenna 5. The police and animal local transmitter/receiver units 40 can connect to other animal and police local receivers/transmitters 40 to exchange messages and updates about the situation. The local receivers/transmitters 40 may comprise rods, wands, portable devices, etc., which can move through the air to detect the signals from the other local receiver/transmitter units 40 or the individual “Goldfish” watches 1. The local receivers/transmitters 40 can detect the signal from the “Goldfish” watch unit's antenna 5 to determine the precise location of the “Goldfish” watch 1. The ground signals may be sent over cellular transmissions, wireless capabilities, radio frequency, or any other communications technology. The local receiver/transmitters 40 can light up to provide a visual signal of the tracking signal from the “Goldfish” watch 1.
In another embodiment, the local receiver/transmitter unit 40 can access the satellite system 13. The local receiver/transmitter unit 40 can send and/or receive a signal to the satellite system 13 and can obtain a GPS signal for tracking the local receiver/transmitter unit's 40 location. The local receiver/transmitter unit 40 can use its location signal and the location signal from the “Goldfish” watch 1 to determine the distance from the local receiver/transmitter unit 40 to the “Goldfish” watch 1. Once the local receiver/transmitter unit 40 has come within a close range of the “Goldfish” watch 1, the local receiver/transmitter unit 40 can use ground communication technology to ascertain a more precise location of the “Goldfish” watch 1 as described above. In this case, rescue animals or people who use the local transmitter/receiver units can receive a satellite signal from the satellite system 13 in order to locate the “Goldfish” user who is also receiving a satellite signal from the satellite system 13.
Operation of System in Emergency and Non-Emergency Modes
In an emergency situation, a user can initiate a signal to call for help by placing the “Goldfish” toggle switch 52 in the correct mode and pressing a “Goldfish” signaling button. The signal can be sent to the satellite system 13. The “Goldfish” unit 1 is in constant communication with the satellite system 13, which helps identify the location of the “Goldfish” user. The “Goldfish” unit 1 can send the location to the satellite system 13 and the satellite system 13 can send the signal to the ground monitoring units 20, 22, 24, 26. After each party has been contacted, the satellite system 13 will relay a message back to the “Goldfish” unit 1 that the proper people have been notified of the situation and location.
In an emergency situation, the authorities can send a signal to users regarding threatening conditions, other local conditions, or to locate a “Goldfish” user. If there is a high threat warning or dangerous weather conditions, the authorities can send a message by way of the ground monitoring units 20, 22, 24, 26. The ground monitoring units 20, 22, 24, 26 can send the message to the satellite system 13 and the satellite system 13 can send the message out to all users in the appropriate area. In this case, people can be alerted of an emergency situation beforehand. The authorities can also send a signal by way of the ground monitoring units 20, 22, 24, 26 to obtain the location of a “Goldfish” user. In the case of a missing, injured, trapped person, etc., the location of a “Goldfish” user can be ascertained by sending a message to the ground monitoring units 20, 22, 24, 26. The ground monitoring units 20, 22, 24, 26 can send a signal to the satellite system 13 to force the “Goldfish” unit 1 to turn on and receive incoming GPS signals. The “Goldfish” unit 1 can determine its location from the GPS subsystem 15. The “Goldfish” unit 1 can send the signal to the satellite system 13. The ground monitoring units 20, 22, 24, 26 can accept the signal from the satellite system 13, which can inform the authorities, families, friends, etc.
In a non-emergency situation, the authorities can locate a user or send warning messages when the situation is not an immediate emergency. The authorities send a signal by way of the ground monitoring units 20, 22, 24, 26. The ground monitoring units 20, 22, 24, 26 can specify the identification code of the user to whom the message should go. The ground monitoring units 20, 22, 24, 26 can send the signal to the satellite system 13. The satellite system 13 can access the “Goldfish” units 1, and therefore the “Goldfish” units 1 are now in contact with the satellite system 13. The satellite system 13 can provide the local, state, or national authorities with the GPS location and other data concerning the surroundings of the user. A message can also be sent to the satellite system 13 from the ground monitoring units 20, 22, 24, 26 and then relayed to the “Goldfish” user. The message can contain information about weather conditions or possible national security threats, etc.
In summary, “Goldfish” is primarily a system used to locate persons in distress, either actively, where the system actively transmits the location of the person to the authorities or passively by detecting the direction and/or distance from the rescuer to the distressed person.
In active mode, the “Goldfish” unit 1 communicates with the GPS subsystem 15 to determine the location of the user. The user's location is then transmitted via the satellite system 13 to the authorities 20, either at the request of the user or at the request of the authorities. Also, in active mode, the “Goldfish” unit 1 transmits locally via antenna 5 to search and rescue units 40. In active mode, a search and rescue unit 40 determines the location of the unit 40 via the GPS subsystem 15. Knowing the location of the search and rescue unit 40 and the location of the “Goldfish” unit 1, the unit 40 can determine the distance and direction to the user.
In passive mode, the search and rescue unit 40 determines the direction and distance through methods such as range finding, signal strength, triangulation, etc., using a local signal transmitted by antenna 5.
An alternate embodiment of a combined “Goldfish” unit and fish finder 100 is shown in FIG. 3. The combined unit 100 is used near or on bodies of water, such as the ocean 110. The combined unit 100 uses readily available technology to detect fish 105, and in particular, dangerous fish, such as sharks, in the ocean 110. When dangerous fish 105 are detected, the combined unit 100 transmits a warning signal to the satellite system 13 which in turn transmits warning signals to any “Goldfish” units 1 within a predetermined distance of the combined unit 100 to warn others of the unseen danger in the ocean 110. The combined unit 100 functions similarly to the “Goldfish” unit 1 in that the combined unit 100 communicates with the satellite system 13 to determine its position, which is then used by the satellite system 13 to determine which “Goldfish” units 1 should receive the danger warning.
From the above description it can be seen that the satellite communications system of the present invention is able to overcome the shortcomings of prior art units by providing a communications network, which is able to communicate between individual “Goldfish” watch units 1, a satellite system 13, ground monitoring units 20, 22, 24, 26 and local receivers/transmitters 40 to locate, track, and message between individuals and objects anywhere around the world.
