Rugged Linux wrist computer upgraded

Nov 17, 2008 — by Eric Brown — from the LinuxDevices Archive — 37 views

Just in time for the latest 007 movie release, Eurotech subsidiary Parvus announced a new version of its military-targeted personal wrist computer. The Linux-ready Zypad WR1100 offers a faster Marvell PXA 270 processor, more memory, a higher-resolution display, plus ZigBee and fingerprint scanner options.

Designed for harsh field conditions where hands-free operation is desirable, the Zypad WR1100 is designed to meet MIL-STD-810F environmental and MIL-STD-461E EMI requirements, says Parvus. The GPS-enhanced device is aimed at military, homeland defense, first responder, security, and emergency service field and in-vehicle applications.

The first Parvus Zypad, the still-supported WL-1000 (pictured at right) shipped in 2006. Later that year Frost & Sullivan awarded the device a 2006 Product Innovation Award in the field of “ambient intelligence.”

Whereas the WL-1000 offers a choice of Linux or Windows CE, the new WR1100 is offered exclusively with Linux. In place of the Raza Microelectronics 32-bit MIPS-based AU 1100, the WR100 is equipped with a Marvell PXA 270 clocked at 416MHz, and it comes with 256MB RAM, 128MB flash, and an SD card, says Parvus. The device offers a higher-resolution (640 x 480) 3.5-inch touchscreen that is said to be protected against water and dust ingress.

Like its predecessor, the WR1100 is equipped with 802.11 b/g, Bluetooth, a GPS receiver, and accelerometers. In addition, it provides a ZigBee short-range wireless option in place of the Bluetooth radio, and also offers options for an electronic compass and a biometric fingerprint sensor, says the company. Other options in the modular design include hot-swapping the GPS receiver with a GPRS cellular module.

The rugged device comes in a fiberglass-reinforced nylon/magnesium alloy case, and offers a rigid wrist support system with ergonomic positioning controls, says Parvus. Like the original Zypad, the WR1100 offers an orientation sensor that detects when the user lowers the arm on which the device is strapped, and automatically places the unit in a standby mode to conserve power. A “tilt and dead reckoning system,” meanwhile, can determine if a user is motionless or has fallen down, resulting in the transmission of a locator beacon signal.
