Tripod Data Systems (TDS) announced two new modules for the TDS Recon rugged handheld computer. The AA PowerBoot Module allows users to run the Recon with two AA alkaline or lithium batteries. The Extended CF-Cap provides room for large CompactFlash (CF) cards such as GPS, LAN and wireless modems. Equipped with either module, the Recon remains ultra-rugged and water resistant. Like the standard rechargeable NiMH PowerBoot Module, the AA PowerBoot Module includes a standard 9-pin serial port and a USB port for connecting the Recon to a PC for rapid data transfer. At room temperature, the Recon can run for about eight hours with two AA alkaline batteries or 16 hours with two AA lithium batteries. The Extended CF-Cap supports larger CF cards including GPS receivers and 802.11 wireless devices. It features a base piece for connecting to the Recon, along with a mounting and quick-release locking mechanism for the extended cap. The cap is composed of radio-wave transparent materials to improve the performance of enclosed GPS and wireless devices. As with the standard CF-Cap, the Extended CF-Cap is completely sealed to protect the CF devices from dust, dirt, water and impacts from accidental drops. (TDS, Corvallis, Ore.)
