A power electronics device with an improved human interface module (HIM) is provided. More specifically, a motor drive is provided that includes a HIM with a portable memory device that stores the programming configuration of the motor drive. The improved HIM with portable memory enables improved techniques for quickly and efficiently updating the programming configuration of one or several motor drives.

A polygonal-shaped confetti () having at least one folded portion (). As illustrated herein the polygonal-shaped confetti is rectangular-shaped confetti that is placed in stacks () folded on a first end () and/or a second end (). The folded portions slow the descent of the confetti and cause the confetti to turn, spiral and dance in the air. The confetti is created by cutting material, such as paper, tissue, plastic, mylar and so forth into substantially elongated polygonal-shaped pieces and then folding in the middle or on one or both ends over of the stack. The confetti may then be a storage device such as a bag (), box, tube, rubber bands and so forth that maintains the shape of the confetti until use.

A stability control algorithm is provided for a centrifugal compressor. The stability control algorithm is used to control a variable geometry diffuser and a hot gas bypass valve (when provided) in response to the detection of compressor instabilities. The stability control algorithm can adjust the position of a diffuser ring in the variable geometry diffuser in response to the detection of a surge condition or a stall condition. The diffuser ring in the variable geometry diffuser can be adjusted to determine an optimal position of the diffuser ring. The stability control algorithm can also be used to open a hot gas bypass valve in response to the detection of continued surge conditions.
