Abstract: A method of monitoring the temperature of a solid state switch in an aircraft solid state power controller. The method includes: measuring an electric current (I) flowing through the solid state switch; calculating, based on the measured electric current (I), an introduced electric power (Pel) that is introduced into the solid state switch within the predefined time period (?t); calculating an increase in temperature (?T) of the solid state switch that is caused by the introduced electric power (Pel); calculating an actual temperature (Tact) of the solid state switch by adding the calculated increase in temperature (?T) to an ambient temperature (Tamb); and comparing the calculated actual temperature (Tact) with a predefined temperature threshold (Tth) and determining an overheat condition if the calculated actual temperature (Tact) exceeds the predefined temperature threshold (Tth).

Abstract: An extensible project system for software development is provided by allowing a flavor, with a specific purpose, to be applied to a base project system. More than one flavor may be applied. Where components are distributed objects, such as where COM (component object model) is used, the project system is assembled by aggregation of a base project object, which contains some data for creating a project system with a flavor object, which modifies the project system. The base project object is the participating object in the aggregation and the flavor object is the controlling object. Multiple flavors may be applied to create a project system intended for multiple purposes, corresponding to the applied flavors.

Abstract: A primary file can be used to specify default build properties for software under development. A set of modified build properties may be stored in a supplemental file. The default build properties can be temporarily overridden with modified build properties for a given build, allowing freedom in the choice of build properties without proliferation of files used for the same purpose, which can be confusing. In addition, users can create new build commands for software under development, and associate the new commands with supplemental files. When the user invokes a new build command, the build process can override the default properties with the modified properties in the supplemental file, and then restore the defaults. Other advantages and features of the invention are described below.

Abstract: Custom build tools are integrated into a design environment build process without writing code. Properties of the tool are defined in a file describing the appropriate syntax of the tool's command line. Values are specified for a particular use of the tool in a particular project. At runtime the command line for the tool is generated from the generalized syntax as defined in the file and the stored values.
