A power management system () includes a group of individually powered electronic devices (-) connected with a power management controller (). The power management controller () operates to determine the operation and charge of each power source of the electronic devices (-) for managing the power source life of at least one of the devices through the use of pre-selected power management algorithms. These include a preprogrammed and predictive algorithm () based on anticipated or actual device activity, a priority algorithm () based on device priority or a maximize work shift algorithm () based on the time period of the user's work shift.

A method for determining the switching frequency of a DC-to-DC power supply for a portable radio transceiver () includes determining a first group of switching frequencies () and then determining the switching harmonics based on that group of switching frequencies (). These switching harmonics are then compared to a group of desired radio channels () where it is then determined if the switching frequencies interfere with the group of desired radio channels (). Based on these results, a second group of switching frequencies is selected if the first set of switching frequencies provides an undesired level of interference ().

A re-configurable interface used in modular electronic architectures includes a host () and one or more modules () for interfacing with the host () to provide additional functionality. A configuration controller () located in the host () is for reading a memory device () located in the module () for providing configuration information to the host. The pin controller () then is able to reconfigure pins of the host connector () to communicate with the module ().
