International Classification:

H05K 702

US Classification:

361760, 361600, 361679, 257727, 73756

Abstract:

A novel pressure sensor housing configuration and method of assembly are described. A pressure transducer including a tube for measuring pressure and leads for providing signals indicated of the measured pressure is mounted to a printed circuit board. A housing including elongated mounting portions or legs taller than the pressure sensor transducer and a cavity for receiving the tube is mounted over the pressure transducer to the printed circuit board. The housing is connected to the printed circuit board using the elongated mounting portions. A pneumatic connection to the housing provides a pressure to be measured to the cavity and thence to the pressure transducer tube.

Abstract:

An electronic power module (EPM) for an agricultural vehicle is provided. The EPM is configurable by an electronic control unit (ECU) to which it is connected by way of a controller area network (CAN) bus. The CAN bus network includes a plurality of electronic control unit (ECU)s and a plurality of EPMs, wherein each of the EPMs is coupled to a corresponding ECU of the plurality of ECUs to be controlled thereby. Each EPM includes an EPM circuit having at least one microcontroller, a driver circuit and a CAN bus communication circuit. The driver circuit is coupled to the microcontroller and is configured by the microcontroller. The driver circuit has a plurality of driver subcircuits. The CAN bus communication circuit is coupled to the microcontroller configured to receive CAN bus messages that include driver configuration instructions and driver current limits from a corresponding ECU and instructions to the microcontroller. The microcontroller receives the driver configuration instructions from the CAN bus communications circuit and responsively configures the driver subcircuits according to the driver configuration instructions.
