This requires time both during the dive and after; moreover interpretation mistakes are always possible mostly during the transfer of the data from the slate to another support. Another \u201cold beast\u201d of scientific divers is to know their precise location while underwater so to geo-correlate the collected data. In many situations failing to precisely locate the proper spatial location of the collected information make them useless. So far the only available method was to use a compass thrusting the dead reckoning ability of the diver.\u00a0All this could be part of the past thanks to an innovative device that couples the functionality of electronic computer forms with the accuracy of GPS navigation. It is the new\u00a0<a href=\"http:\/\/allecoproducts.fi\/alltab\/\">Alltab<\/a>\u00a0which has been recently presented at DEMA 2017 hosted in Orlando (FL) in November 2017.<\/p>\r\n<p style=\"text-align: justify;\"><strong><span style=\"font-size: 14pt; color: #008000;\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-18855 alignleft\" src=\"https:\/\/www.ocean4future.org\/savetheocean\/wp-content\/uploads\/2018\/01\/alltab.jpg\" alt=\"\" width=\"421\" height=\"279\" srcset=\"https:\/\/www.ocean4future.org\/savetheocean\/wp-content\/uploads\/2018\/01\/alltab.jpg 2048w, https:\/\/www.ocean4future.org\/savetheocean\/wp-content\/uploads\/2018\/01\/alltab-300x199.jpg 300w, https:\/\/www.ocean4future.org\/savetheocean\/wp-content\/uploads\/2018\/01\/alltab-768x509.jpg 768w, https:\/\/www.ocean4future.org\/savetheocean\/wp-content\/uploads\/2018\/01\/alltab-1024x678.jpg 1024w\" sizes=\"auto, (max-width: 421px) 100vw, 421px\" \/><span style=\"font-size: 18pt;\">Riassunto<\/span><br \/><\/span><\/strong>La raccolta dei dati \u00e8 una delle attivit\u00e0 principali per i subacquei scientifici ed \u00e8 di solito un lavoro scrupoloso che richiede di scrivere su una lavagna portatile subacquea, indossando guanti ingombranti in maniera tale da essere in grado in un secondo tempo di leggere e capire ci\u00f2 che si \u00e8 scritto per poi inserire i dati raccolti in un&#8217;applicazione o su computer. Ci\u00f2 richiede tempo, sia durante l&#8217;immersione che nella fase seguente fuori dell&#8217;acqua; inoltre possono verificarsi degli errori di interpretazione durante il trasferimento dei dati dalla lavagna ad un altro supporto. Un&#8217;altra &#8220;vecchia bestia&#8221; dei subacquei scientifici \u00e8 quella di conoscere la loro posizione precisa sott&#8217;acqua in modo da correlare geograficamente i dati raccolti. In molte situazioni non riuscire a localizzare con precisione la corretta posizione spaziale delle informazioni raccolte li rende inutili. Finora l&#8217;unico metodo disponibile era quello di usare la vecchia cara bussola per cercare di geo-referenziare la grande quantit\u00e0 dei dati raccolti con triangolazioni sia in superficie che sott&#8217;acqua. Procedura non complessa tutt&#8217;altro che facile quando la precisione della raccolta dei dati era essenziale per il ricercatore scientifico subacqueo. Tutto ci\u00f2 potrebbe far parte del passato grazie a un dispositivo innovativo che abbina la funzionalit\u00e0 delle forme di computer elettronici all&#8217;accuratezza della navigazione GPS. \u00c8 il nuovo <strong><span style=\"color: #008000;\">Alltab<\/span> <\/strong>che \u00e8 stato presentato di recente a DEMA 2017, ospitato a Orlando (Florida) nel novembre 2017.<\/p>\r\n<p><span style=\"font-size: 18pt;\"><strong><span style=\"color: #008000;\">Alcune caratteristiche:<\/span><\/strong><\/span><br \/>Profondit\u00e0 operativa: 0-150 m (versione Mil PRO), 0-90 m (versione TechRec)<br \/>Tablet: Samsung Galaxy Tab S2 8 &#8220;(incluso)<br \/>Dimensioni e peso: 264 \u00d7 175 \u00d7 21 mm, 1425 g.

The tablet has a fully functional touchscreen that can be used underwater down to a maximum depth of 150 meters (490 ft). A \u201clighter version\u201d can be used down to 90 meters (295ft). The casing is sealed and does not require to be opened for any operation including the recharging of the tablet that happens through an induction system. This feature strongly reduces the risk of leakage. The scientific applications of Alltab include electronic data collection (also georeferenced), navigational features and the possibility of connecting and controlling other devices. For the data collection a specific software (Allure) has been developed. It is a web-based SaaS that works on any internet browser. One can design e-forms and synchronize them with any desktop or mobile device with an internet access. The forms work also offline, so that one can collect data even without internet connection; the data are then send to a cloud or a local server once the internet connection is available. For a research project this provides a big advantage and it is time saving, because data are immediately available for all research team members with access credentials.<\/p>\r\n<p style=\"text-align: justify;\"><div class=\"lyte-wrapper fourthree\" style=\"width:420px;max-width:100%;margin:5px;\"><div class=\"lyMe\" id=\"WYL_gxOlF_6XDFM\"><div id=\"lyte_gxOlF_6XDFM\" data-src=\"\/\/i.ytimg.com\/vi\/gxOlF_6XDFM\/hqdefault.jpg\" class=\"pL\"><div class=\"tC\"><div class=\"tT\"><\/div><\/div><div class=\"play\"><\/div><div class=\"ctrl\"><div class=\"Lctrl\"><\/div><div class=\"Rctrl\"><\/div><\/div><\/div><noscript><a href=\"https:\/\/youtu.be\/gxOlF_6XDFM\" rel=\"nofollow\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i.ytimg.com\/vi\/gxOlF_6XDFM\/0.jpg\" alt=\"YouTube video thumbnail\" width=\"420\" height=\"295\" \/><br \/>Guarda questo video su YouTube<\/a><\/noscript><\/div><\/div><div class=\"lL\" style=\"max-width:100%;width:420px;margin:5px;\"><\/div><\/p>\r\n<p style=\"text-align: justify;\">The navigation software \u201c<strong><span style=\"color: #008000;\">Valtamer Navigator<\/span><\/strong>\u201d has offline background maps and a user interface especially developed for underwater use. One can add and name waypoints, mark locations while diving, and also import pre-defined coordinate points and export the waypoints marked while diving. This simplify the data geo-referencing, allowing a clear and univocal geographic position of the collected information. The tablet is also able to control a variety of external devices including video and acoustic systems and also more specific scientific instruments such as a coral metabolism measurement device specifically developed at the University of North Carolina, Wilmington by Alina Szmant and her team. The Alltab therefore can be used as a central hub to manage and collect data from several scientific monitoring systems. For the underwater positioning the Alltab accepts a short-baseline acoustic system \u201cAquametre D-100 NG\u201d. The system is based on the geometric triangulation of multiple acoustic transmitters and it is designed to accurately defining the position of the diver within a 3-D spherical volume of about 400 meters of diameter.<\/p>\r\n<p style=\"text-align: justify;\">Another navigational feature of the tablet is the possibility of using a GPS device, with a floating wired antenna, called \u201c<span style=\"color: #008000;\">Allhub<\/span>\u201d. In an extended version of the system a mobile phone can be connected to the antenna allowing for full-speed mobile internet connection and positioning capabilities based on the Android smartphone system. Last but not least the Alltab works with any Android application and has Wi-Fi and Bluetooth connectivity.<\/p>\r\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-18858\" src=\"https:\/\/www.ocean4future.org\/savetheocean\/wp-content\/uploads\/2018\/02\/27265208_10214453471507918_194296667_o.jpg\" alt=\"\" width=\"925\" height=\"616\" srcset=\"https:\/\/www.ocean4future.org\/savetheocean\/wp-content\/uploads\/2018\/02\/27265208_10214453471507918_194296667_o.jpg 2048w, https:\/\/www.ocean4future.org\/savetheocean\/wp-content\/uploads\/2018\/02\/27265208_10214453471507918_194296667_o-300x200.jpg 300w, https:\/\/www.ocean4future.org\/savetheocean\/wp-content\/uploads\/2018\/02\/27265208_10214453471507918_194296667_o-768x511.jpg 768w, https:\/\/www.ocean4future.org\/savetheocean\/wp-content\/uploads\/2018\/02\/27265208_10214453471507918_194296667_o-1024x682.jpg 1024w\" sizes=\"auto, (max-width: 925px) 100vw, 925px\" \/><\/p>\r\n<p style=\"text-align: justify;\"><span style=\"font-size: 18pt;\"><strong><span style=\"color: #008000;\">Applications<\/span><\/strong><\/span><br \/>Being myself a scientific diver, I am extremely interested in the potential applications of an underwater system able to both store data and provide accurate navigation. As example it could be possible to define a grid of sampling points and then swim along a pre-planned path guided by the GPS accurately collecting the needed information filling a customized electronic form that can be then immediately shared online with other researchers. In complex multi-operators projects this would be a great time-saving procedure; moreover the data will be safe in a remote storage so that even if the tablet fails the collected information will be still available.<\/p>\r\n<p style=\"text-align: justify;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-18859\" src=\"https:\/\/www.ocean4future.org\/savetheocean\/wp-content\/uploads\/2018\/02\/27265262_10214453472827951_38137096_o.jpg\" alt=\"\" width=\"935\" height=\"622\" srcset=\"https:\/\/www.ocean4future.org\/savetheocean\/wp-content\/uploads\/2018\/02\/27265262_10214453472827951_38137096_o.jpg 2048w, https:\/\/www.ocean4future.org\/savetheocean\/wp-content\/uploads\/2018\/02\/27265262_10214453472827951_38137096_o-300x200.jpg 300w, https:\/\/www.ocean4future.org\/savetheocean\/wp-content\/uploads\/2018\/02\/27265262_10214453472827951_38137096_o-768x511.jpg 768w, https:\/\/www.ocean4future.org\/savetheocean\/wp-content\/uploads\/2018\/02\/27265262_10214453472827951_38137096_o-1024x682.jpg 1024w\" sizes=\"auto, (max-width: 935px) 100vw, 935px\" \/><\/p>\r\n<p style=\"text-align: justify;\">The mobile telephone connectivity is also a great safety feature allowing divers to be in touch with the surface team exchanging text messages through the dive. This is also a powerful tool during training sessions where one instructor can monitor and exchange even complex information with multiple students using written messages or other visual aids such as pictures and pictograms. The Alltab is definitely a powerful tool that can be used in a variety of situations providing a reliable support for any diver involved in data collection and accurate navigation.<\/p>\r\n<p style=\"text-align: justify;\"><strong><span style=\"color: #008000;\">Giorgio Caramanna<\/span><\/strong><br \/><span style=\"color: #ffffff;\">.<\/span><\/p>\r\n<p style=\"text-align: justify;\">Alcune delle foto presenti in questo blog possono essere state prese dal web, citandone ove possibile gli autori e\/o le fonti.
