Abstract: Systems and methods are provided for enhancing diagnosis of control logic by automatically triggering latent or quiescent diagnostic logic in response to a CAN bus signal and without requiring a software update of the control logic. The diagnostic logic may be triggered to provide an increase in the frequency of CAN messages that are generated. The diagnostic logic may be further triggered to provide a generation of additional CAN messages reporting operation signals beyond those that are normally generated. The diagnostic logic may be further triggered to provide higher priority to selected CAN messages reporting operation signals. The diagnostic logic may be still further triggered to one or more of increase the frequency of selected CAN report messages, generate additional CAN messages reporting operation signals beyond those that are normally generated, and/or provide higher priority to selected CAN messages reporting operation signals, each without requiring a software update.

Abstract: A work vehicle including a chassis, a ground engaging implement configured to move the chassis along a ground surface, a boom connected to the chassis, an arm connected to the boom, and a bucket connected to the arm. A first actuator rotates the boom with respect to the chassis, second actuator rotates the arm with respect to the boom, and a third actuator rotates the bucket with respect to the arm. A processor calculates a first cycle time of operation of the first actuator, and analyzes if the calculated first cycle time is valid. If the first cycle time is valid, the processor communicates the calculated first cycle time to a user, and if the first cycle time is not valid, the processor repeats the calculation of the first cycle time of operation of the first actuator.

Abstract: This present invention relates to a device for the measurement of the amount of oxygen in a gas mixture, or other gas with significantly different magnetic susceptibility than the background gas mixture, by the use of a suspended test body in a magnetic field that experiences force due to the magnetic susceptibility of the measurand gas. In order to enable a fast time response for the system with a change in oxygen concentration, a flow regime is presented which allows a fast sweep of the measurement volume combined with adjustable, balanced pressure drops via a flow balancing element (or elements) within the flow channels to independently minimise flow related uncertainties.

Abstract: An apparatus for the measurement of the magnetic susceptibility of a gas mixture comprises: a gas sample chamber (8) adapted to receive the gas mixture; a test body (1) rotatably suspended within the gas sample chamber; magnets (10) within the gas sample chamber; a compact optical system for detecting rotation of the test body (1) including a light source (12), photodetectors (13) arranged to detect a light signal, and a mirror (5) attached to the test body (1). An actuation system is arranged to keep the test body (1) substantially at a null position. The optical system comprises at least one photodetector positioned on each side of the light source. The light source is arranged to emit a light beam towards the test body. The photo detectors are arranged to each detect an edge of a light beam reflected from the mirror.
