AA battery pack boosts Nomad operation.* Trimble of Sunnyvale, Calif., has developed an ace in the hole for its high performance Nomad hand-held computer Noun 1. hand-held computer - a portable battery-powered computer small enough to be carried in your pocket hand-held microcomputer portable computer - a personal computer that can easily be carried by hand . Technicians have perfected an AA size battery module that allows the computer to run an extra four hours in the field after organic lithium batteries Lithium batteries are primary batteries that have lithium metal or lithium compounds as an anode. Depending on the design and chemical compounds used lithium cells can produce voltages from 1.5V to about 3V, twice the voltage of an ordinary zinc-carbon battery or alkaline cell. are drained. The module ensures uninterrupted operation of the Nomad and offers a comparable level of performance even when inadvertently dropped. A special capacitor capacitor or condenser, device for the storage of electric charge. Simple capacitors consist of two plates made of an electrically conducting material (e.g., a metal) and separated by a nonconducting material or dielectric (e.g. prevents the unit from resetting. As for the computer, which was launched last July, it offers an 806 megahertz One million cycles per second. See MHz. MegaHertz - (MHz) Millions of cycles per second. The unit of frequency used to measure the clock rate of modern digital logic, including microprocessors. PXA320 xscale processor, 128 standard, with built-in802.11g optional wireless communication.
