Abstract: The method provides for a way to ensure that the application program running on the host computer handles data received from the at least one mobile computer terminals when one of the mobile computer terminals goes out of range of the wireless network. Communication and association may be established between a mobile computer terminal and an access point on a local network. Then, when it has been determined that communications between the mobile computer terminal and the access point have been impeded, the mobile computer terminal may switch to batch mode to continue data collection.

Abstract: A portable data device system includes a portable data device and a cradle for receiving the portable data device. The cradle is arranged to recharge the portable data device power supply and/or upload or download information to and from the portable data device. The cradle and portable data device are in wireless communication allowing a minimum of processing and data storage capability at the front end and hence operation of the portable data device as a thin client.

Abstract: A data terminal includes a digital camera for capturing an image and data processing/storage/encoding means for processing the image information, together with an internal server for creating a web site at the terminal displaying the image. As a result high resolution image information is immediately accessible to authorized users and instantly recorded.
