“If we’re planning a trip out to the range… we can check the documents out, carry them with us all day on the iPad, edit them all day… and then upload them back to our notebooks when we get back to the office with an internet connection.” With the Apple iPad mobile device & iCERF, technicians can continually access documents, data, and notes residing in their digital laboratory notebooks. Wi- Fi access for communication with cloud-based servers, however, is not always attainable in the field. To address this need, iCERF delivers an off-line mode enabling productivity to continue even when network connectivity becomes unavailable.
