One of the world's largest manufacturers of professional natical electronic charts, NAVIONICS, of Woods Hole, has developed a new credit card-size electronic chart module called the NAVIONICS Microchart. The Microchart uses the latest memory card technology and employs "flash memory" devices which consume little power and require no batteries. Several of the world's leading marine electronics equipment companies are utilizing the Microchart in their new product lines.
The Microchart combines a large 128 MB memory storage facility that is the equivalent to hundreds of navigational charts, with the fast data access that is essential to safe navigation.
NAVIONICS electronic charts are now available in either cartridge or Microchart format starting at $150.
The company reports that its seamless database of over 6,000 navigational charts is the largest in the world.

controls logging functions, radio communication, serial communication, and speed and navigation control. Sensor data is collected at 1Hz, and stored in flash memory. The data can also be transmitted, in real-time, to other vehicles or a shore-based station. A custom printed circuit board (PCB) connects the various

Self powered by batteries, the system contains compact flash memory storage and an Iridium satellite communications link. www.seadiscovery.com In 1992, MBARI scientists Gernot Friederich and Francisco Chavez
the design, construction, and sea-testing of a sophisticated Optical Sediment Trap that makes use of "better optics, a little CPU, and a fourgigabyte flash memory -- the kind of components you can find in hand-held computers and consumer digital cameras these days." The sample chamber was fabricated at the

Since the hardware is designed for installation in switchgear panels or other industrial environments often high in temperature and vibration, flash memory is utilized to eliminate the moving parts in a traditional hard drive, which im- proves robustness.

The important voyage sta- tus information is held in the non- volatile flash memory for subsequent analysis of the factors surrounding an incident.
