    摘要： Methods and apparatus to monitor conditioning machines are disclosed herein. An example system includes a plurality of work rolls to process a strip material. A first sensor detects a first distance between an upper surface of the strip material and a first reference location and a second sensor detects a second distance between an upper surface of the strip material and a second reference location. A controller determines a difference value between the first distance and the second distance to detect material curvature of the strip material.

Preferably, the LED lighting module comprises a first LED base, a central LED base containing a printed circuit board, and a third LED base, where the first and third bases are connected by spacer tubes. Each LED base has an LED pc-board mounted thereon. A main power line runs through the set of three LED bases. A first series connector line connects the printed circuit board to the first LED board and a second series connector line connects the printed circuit board to the third LED board. A first connection line connects the first LED board to the central LED board and a second connection line connects the central LED board to the third LED board. These LED module sets can be connected consecutively to create strings of series wired sets from the same main power lines.

    摘要： Power inverters include a frame and a power module. The frame has a sidewall including an opening and defining a fluid passageway. The power module is coupled to the frame over the opening and includes a substrate, die, and an encasement. The substrate includes a first side, a second side, a center, an outer periphery, and an outer edge, and the first side of the substrate comprises a first outer layer including a metal material. The die are positioned in the substrate center and are coupled to the substrate first side. The encasement is molded over the outer periphery on the substrate first side, the substrate second side, and the substrate outer edge and around the die. The encasement, coupled to the substrate, forms a seal with the metal material. The second side of the substrate is positioned to directly contact a fluid flowing through the fluid passageway.
