Abstract: An improved fume hood that has an external sensor that automatically controls at least one lighting fixture located on or in the fume hood such that when a person is sensed in front of the fume hood, the light in the fume hood will automatically turn on. Once the technician is not sensed in front of the fume hood, the control module will delay and then turn the fume hood light off.

Abstract: A production management system and method for managing the production of a custom designed product including user-friendly product configuration software to configure the product, such as an AHU, to the user's requirements. Once the product has been configured, manufacturing resource planning software automatically provides information from the product configuration software to generator software. The generator software corresponds to each uniquely configurable component of the product to automatically produce a customized model of the component, or customized component, for use with the custom product. The manufacturing resource planning software automatically prepares drawings of the customized component for manufacture.
