摘要:
An apparatus is provided for sensing an angular position of a shaft or other rotatable body. The apparatus preferably includes a first and second housing portion. A circuit connected to a circuit board is housed in the housing and includes a plurality of proximity sensors. A rotatable member is rotatably attached to the circuit board and includes a position indicator. The circuit produces a signal as a function of the position of the rotatable member.

A power and data delivery system for a machine. The system includes a conductor located throughout at least a portion of the machine for delivering power, a plurality of nodes, each connected to the conductor at a respective location, and a plurality of devices, each connected to a corresponding node. At least one node controls the delivery of power and data by way of a message containing a unique identifier for that one node.
摘要:
A diagnostic system for an internal combustion engine includes a pressure sensor configured to measure pressure within a combustion cylinder. An electronic controller is configured to receive a pressure signal from the pressure sensor, analyze the pressure signal by at least partially comparing the pressure signal to a predetermined pressure signal, and diagnose a failure of one or more piston ring seal(s), an intake valve, and an exhaust valve of the engine based on a difference between the pressure signal and the predetermined pressure signal.
