Abstract: A man-portable incident command platform is provided. A controller for a rechargeable battery system is disclosed that evaluates whether a cover of the rechargeable battery system is open or closed; determines whether an AC power source is available; evaluates a charge level (for example, from a system management bus) of one or more batteries in the rechargeable battery system; and enables a charging circuit for one or more batteries requiring a charge based on whether the cover of the rechargeable battery system is open or closed and if the AC power source is available A charging circuit for the rechargeable battery system is disclosed that comprises one or more programmable voltage sources for charging one or more batteries in the rechargeable battery system.

Abstract: A totem pole output stage including first and second control modules cross coupled to first and second switching modules for measuring the charge on the gate of a FET contained in the opposing switching module to determine the condition of the opposing switching module, so as to avoid mutual conductivity events without the use of a fixed timing delay while maximizing switching performance.

Abstract: An improved input module is able to sense the ON and OFF states associated with an external signal, wherein that signal complies with standards denoting the ON and OFF condition thereof. The improved input module includes a fixed impedance and a parameter sensor, such as a voltage sensor, which senses at least a portion of the voltage drop across the impedance. In addition, the module includes a current limiter in series with the impedance so as to limit the current flow through the impedance when the threshold parameter has been exceeded. An additional embodiment of the input module includes a second current limiter which is able to selectively detect broken wires associated with the connection of the external signal to the input module.
