Abstract: The present invention has a controller (010) to monitor the environmental temperature of automotive or industrial sensor (830) and a means of actively heating (651) or cooling (520) sensors such that the sensor (830) is not exposed to extreme cold or hot temperatures, which could negatively affect the operation of the sensor (830) either temporarily or permanently. The operator (901) is informed (356) of the future probability of measurable degraded performance of the automotive or industrial machine or thermal stress of sensors to enable the operator (901) to adjust her operation (910) of the machine and perform preventive maintenance to reduce the future probability of measurable degraded performance and thermal stress of sensor (830). There can be a plurality of sensors.

Abstract: A suspension axle has beams that are bolted onto the axle. There are plates that are rigidly affixed to the front and rear of the axle with indentations on the inner end of the main portions and secondary portions of the beams that are sized to fit tightly over the plates. Bolts extend through openings in the axle end of the main portion and secondary portion and also through the plates and through the axle. The bolts have nuts thereon to securely hold the main portion and secondary portion in contact with the axle.
