Abstract: An animal call includes a mouthpiece, a barrel, and a reed. The mouthpiece defines an air channel therein and has a reed bed proximate the air channel. The barrel is coupled to the mouthpiece and has an internal chamber that is fluidically coupled to the air channel of the mouthpiece. A surface comprising the air channel varies in order to maintain a substantially constant cross-sectional area magnitude along a length of the channel. The reed is disposed adjacent the air channel and proximate the reed bed.

Abstract: A method and system for producing production control software for a plurality of electronic control modules, is provided. The electronic control modules are located on production machines. Each production machine includes a subset of the electronic control modules. The system includes a part file staging area for receiving and storing new production control software from a design engineering group. A product engineering workstation is coupled to the part file staging area and operated by a product engineering user. The product engineering user can review, modify and approve the new production control software. A production staging area, coupled to the product engineering workstation, receives and stores approved production control software and receives an order for a production machine.
