Abstract: Apparatus, system and method for intelligently tracking and monitoring physical assets worldwide using solar cells, rechargeable battery, two-way satellite communications, a CPU with memory, sensors of various types and GPS in the device and a GIS (Geographic Information System) database for storing and reporting the location and condition of the asset. The apparatus is permanently mounted on the physical asset, e.g., a cargo container, portable construction equipment, etc., where it reports its position and condition to the based unit, based on, movement, a container door being opened, overheating, etc., time passage or on-demand, using satellite communication networks. These reporting criteria are controlled by the system and are set and reset as needed.

Abstract: Methods and systems for reducing power consumption in data communications is presented. Portable devices that interface with peripheral devices reduce power consumption by minimizing the time that a communications port is open. Rather than keeping the communications port open for the duration of a program, the communications port is opened at calculated times to allow bursts of data to pass through and closed in response to certain events. This invention also works with normal power cycling methods of portable devices and peripheral devices to produce even further power savings.
