A fault injection circuit injects a test signal into a data bus with a normal high logic level and a normal low logic level. The test signal has a greater logic level greater than the normal high logic level of the data bus or a lower logic level lower than the normal low logic level of the data bus. An analog-to-digital converter is coupled to a voltage level detector for sensing an aggregate level of an aggregate signal on the data bus. The aggregate signal is composed of the termination circuit signal and the test signal. A diagnostic tool determines whether a faulty connection between the data bus and a network device exists, where the sensed aggregate level exceeds at least one of the normal high logic level and the normal low logic level.

Method and system for diagnosing a fault or open circuit in a network

An inverter comprises output switches for generating motor phase currents for application to an electrical motor based on a commanded torque. A current sensor is arranged for detecting motor phase currents applied to the electrical motor by an inverter. A voltage sensor is configured for measuring voltages applied to the electrical motor by the inverter. An output port is capable of outputting output signals of the detected motor phase currents and measured voltages for processing by a vehicle controller. The output signals are suitable for input to a vehicle controller for determining whether or not to generate an override control signal. An input port is configured for receiving the override control signal from the vehicle controller. The input port is coupled to an override input module for switching off a supply of electrical energy to the electric motor.

Inverter and a method for controlling an electric machine

An electrical switch assembly comprises a generally planar substrate. A functional switch and at least one identification switch are mounted to the substrate. A switch body supports a switch actuator which is movable between multiple positions. An arrangement of one or more projecting members extends from the switch body. The switch body is mounted on or to the substrate such that the switch actuator operatively engages the functional switch, and the arrangement of projecting members operatively engages at least one of the identification switches to create a unique electronic identifier for the electrical switch assembly.

Electronic switch assembly with configurable functionality

An electrical assembly including a housing having an inner surface. At least one mounting feature protrudes from the inner surface. At least one heat sink is inserted onto the at least one mounting feature. At least one electrical component is in thermal contact with a portion of the at least one heat sink.

Reconfigurable heat sink assembly

An operator control assembly including at least one operator control mounted in a panel cover or dashboard with at least one opening for receivably mounting the operator control, and at least one printed circuit board mounted beneath the panel cover. A unique configuration of projecting members on the bottom of the operator control comes in contract with and engages sensors mounted on the printed circuit board. Depending on the number and arrangement of the projecting members, a unique subset o sensors t engaged, providing a unique electronic ID for each operator control installed. This electronic ID can then be transmitted to an electronic control unit, which will alter its operation based on the types of operator controls currently installed.

Self-configuring operator control

A connector assembly comprising includes a housing with a wall and a plurality of connector units. The wall includes a plurality of openings having the same size and shape. Each of the connector units has a base plate, electrical connectors mounted in and projecting from the base plate, a hollow shroud surrounding the electrical connectors and extending away from the base plate, and a skirt surrounding the shroud. The skirt projects radially outwardly from the base plate. All of the skirts have the same outer peripheral size and shape. The shrouds may have a variety of different outer peripheral shapes and sizes corresponding to unique connector functions. Each of the skirts sealingly engage with a portion of the wall surrounding a corresponding opening. Each opening is surrounded by a groove, and each skirt overlaps and covers a corresponding one of the grooves.

Flexible electrical connector/housing assembly

A work machine includes a bulkhead separating an operator cab from an engine compartment. An electronic module includes a cantilever arranged mounting flange mounted to the bulkhead. The electronic module includes a rigid and thermally conductive frame. An electronics board is mounted to one side of the frame, and a power board is mounted to an opposite side of the frame. The electronics board carries a plurality of electronic components, and the power board carries a plurality of replaceable power elements. Each power element is a fuse, relay and/or circuit breaker. A housing encloses the electronics board and the power board. The housing includes an access cover to the power board.

Cantilever mounted electronic module with rigid center backbone

A vehicle having a power and information system including a vehicle structural member, an insulated power conductor, a communication link and a modular distribution system. The modular distribution system is attached to the vehicle structural member. The modular distribution system is coupled with the power conductor and with the communication link. The modular distribution system includes a backbone module having an electrical power connection and at least one plug pack. Each plug pack includes a first connector, a second connector and a controller pack. The first connector is connectable to the backbone module. The second connector has a plurality of terminals. The controller pack selectively electrically connects at least one of the plurality of terminals to the electrical power connection dependent upon information received by way of the communication link.

Modular power distribution system

An electrical connector assembly has first and second connector units which are connectable with each other. One of the connectors has a shell which has a variable number of tabs projecting therefrom. The number and position of the tabs can be selected so that different connectors can be distinguished from each other. A set of switches are mounted on a base adjacent the other connector. The switches are engagable tabs so that the status of the switches represents the number and position of the tabs, thereby generating electrical signals uniquely identifying the connectors.
