Abstract: A rigid plastic enclosure is made from flat blanks. The enclosure is particularly well suited for use as an electrical or electronic component enclosure. The top, bottom, back, and side walls of the enclosure are parts of a structure made by cutting and/or routing a sheet of plastic which can be folded into an open-faced, box-shaped structure. A cover or face plate can be fastened to the structure to complete the enclosure. Because the enclosure is constructed from plastic, holes can be easily drilled into its walls, eliminating the need for providing knockout holes at predetermined locations.

Abstract: A controller for a starter/generator used with an aircraft engine, includes means for monitoring field return current in a generator field winding; means for monitoring generator voltage; and microprocessor control means for adjusting generator field current as a function of the field current and voltage and field return current. The field return current and output voltage monitoring functions allow for open field, field integrity, over voltage, field weakening and torque limiting functions to be realized in an integrated programmable system configuration.
