Water usually doesn't present a uniform acoustic transmission medium as the velocity of sound propagation and iTagPro device different sign transmission traits range with water temperature, salinity, and depth (or pressure) each of which can differ with dive location. Therefore, the transmission time between a transmitting unit and a receiving unit vary with the situation of a dive (i.e., based on the water chemical make-up) and sometimes even with a deliberate depth for a dive. Such gadgets, methods, iTagPro USA and methods ideally could be tailored for iTagPro USA use in various dive locations and beneath completely different water circumstances and can be readily tailored to be used with a number of divers and dive teams of varying expertise and experience. 5 toes for unskilled divers or for dangerous conditions whereas a fifty-foot, hundred-foot, 200-foot, and sometimes higher safety range could also be set for skilled divers or comparatively protected diving situations. An alert can be routinely or manually transmitted to and from the dive grasp when the space is exceeded.

An alarm is activated when the space situation is met by the found distance or when activated by a user. The space is then found from the measured time. FIG. 1 is a block diagram usually illustrating the system of the present invention. FIG. 2 is a movement chart usually illustrating the tactic of the current invention. FIG. 3 is a block diagram illustrating in more element one embodiment of the means for discovering distance in FIG. 1 . FIG. Four is a stream chart illustrating in additional detail the step of discovering distance in FIG. 2 . FIG. 5 is a block diagram illustrating in more element one embodiment of the means for discovering distance in FIG. 1 . FIG. 6 is a stream chart illustrating in more detail the step of discovering distance in FIG. 2 . FIG. 7 is a block diagram illustrating in more detail one embodiment of the means for discovering distance in FIG. 1 .

FIG. Eight is a circulation chart illustrating in additional element the step of discovering distance in FIG. 2 . FIG. 9 is a front view of a diver communication device of the present invention illustrating a show floor exhibiting dive time, current separation distance settings, current message from dive associate or dive grasp, and communication frequency along with other options of the diver communication system. FIG. 10 is a aspect view of the exterior of the diver communication device of FIG. 9 illustrating the battery compartment. FIG. 12 is another functional block drawing just like FIGS. 11A and 11B illustrating the usage of a dive master communication system for concurrently monitoring divers in two separately speaking dive groups that are diving using different safety distances. FIG. 13 is a entrance view of a dive grasp communication machine or iTagPro USA grasp controller illustrating options much like the diver communication system of FIG. 9 and also illustrating options facilitating monitoring and speaking with multiple diver and dive groups.

Additionally, the diver communication system and methodology is helpful for permitting a number of dive teams diving within a single dive space to communicate with each other with out causing communication problems. This discussion consists of an evidence of using preset separation distances and the automatic transmission of alert alerts when the determined distance between two devices exceeds the preset separation distance for the two devices. An essential side of the invention is the combining of a number of features in a single diver communication system and the way the distinctive mixture of these functions facilitates efficient communication between diving companions and, iTagPro USA considerably, between 3 or more divers inside a dive group (even when diving in proximity to other dive groups) and between a dive master and divers in multiple dive teams. FIG. 1 illustrates a system 2 for alerting when a primary device four and a second device 6 are separated by a preset distance. System 2 consists of a way eight for discovering a distance 10 between first gadget 4 and a second device 6 , a comparator iTagPro key finder 12 , and an alarm 14 .

System 2 may also embody various additions equivalent to a consumer input interface sixteen and a storage system 18 for iTagPro USA storing a preset distance situation 20 or iTagPro USA executable directions. First gadget 4 and second system 6 may be of any shape or design. System 2 may have a wide range of uses with each use having its own desired shape. 2 and second gadget 6 are conveniently embodied in a form to be worn on a diver's wrist or connected to the divers Buoyancy Control Device (BCD). Additionally, when utilized by divers, it may be desirable for first gadget 4 and second gadget 6 to include standard diving options comparable to a dive time indicator or other indicators helpful for divers. Four and second device 6 are being described as separate devices. 4 and iTagPro USA second gadget 6 each embrace all the elements of the opposite device. In that embodiment, each of two or extra divers can be ready to keep track of the gap between them.
