Abstract: A fault detection system for a fastener (224) in a machine (100) includes an ultrasonic sensor (404) that is integrated with the fastener and capable of emitting an ultrasonic signal (506) that travels through a length of the fastener (224). The ultrasonic sensor (404) receives a returning ultrasonic signal (506) and a processor (512) calculates a travel time between an emission of the ultrasonic signal (506) and a receipt of the returning ultrasonic signal (506). The processor (512) calculates an actual length (L) of the fastener (224) based on the travel time (510), compares the actual length (L) with a predetermined length of the fastener (224), and emits a wireless signal (519) to an electronic controller (612) of the machine (100) that is indicative of a structural state of the fastener (224).

Abstract: A machine having an air conditioning system includes a compressor having an inlet and an outlet. A manifold having a housing is attached to the compressor and includes a low pressure channel for directing a low pressure refrigerant from a low pressure port of the manifold to the compressor inlet. The manifold also includes a high pressure channel for directing a compressed refrigerant from the compressor outlet to a high pressure port of the manifold. At least one additional port is in fluid communication with one of the high pressure channel and the low pressure channel.

Abstract: The present invention provides an obstacle detection system for a work machine. The obstacle detection system includes at least one sensing device and an interface device. The sensing device is configured to identify the presence of an obstacle in an area around the machine and the interface device is configured to alert an operator to the presence and position of the obstacle with respect to the machine.

Abstract: Exhaust directing mechanisms are useful for directing exhaust gas flow from an inlet to either a vehicle dump body or a muffler means. A valve mechanism for a vehicle includes a valve body having a valving element mounted within the valve body and being rotatable to a first position upon movement of a dump body to a raised position to direct exhaust from an engine to a muffler. With the dump body in the lowered position the valving element is in the second position to direct exhaust to the dump body. This arrangement of components provides for rotation of the valving element to direct exhaust flow to the dump body or to the muffler.
