Abstract: An electric machine stationary assembly is described. The stationary assembly includes a plurality of stacked laminations each comprising a first end and a second end. The stationary assembly also includes a mechanically deformable first fastening feature positioned at the first end of each lamination. The stationary assembly also includes a second fastening feature positioned at the second end of each lamination and configured to cooperate with the first fastening feature to couple the first end to the second end.

Abstract: Various methods and devices are provided for attenuating RF signals propagating within a waveguide. In particular, a plurality of coaxial probes are incorporated into the waveguide for the purpose of attenuating X-band RF signals. In one embodiment, a 7-bit, 3 dB linear digital attenuator is provided having a waveguide in a racetrack configuration. Coaxial probes in communication with the waveguide are adapted to couple energy to and from a signal traveling within the waveguide. The attenuator can also include switches adapted to reflect coupled energy back into the waveguide or pass the coupled energy to a resistive termination.

Abstract: A lid for a container having an open top with a rear wall having a snap slot and a hook slot, the lid having a latch mechanism with a snap member and a hook member projecting downward for positioning in the snap slot and the hook slot, respectively, when the lid is in position on the container, and having a key slot adjacent the snap and hook members. Each of the snap member and the hook member has a cam surface adjacent the key slot for engagement by a key member pushed downward through the key slot to pivot the snap and lock members away from the snap and hook slots, respectively, for removal of the lid from the container. The hook member has an upward and rearward projecting hook adjacent the lower end of the hook member for entering the container hook slot, and the snap member has a rearward projecting shoulder adjacent the lower end of the snap member for entering the container snap slot.
