摘要:
A method and method of estimating fatigue life of a structure is disclosed. In one embodiment, the method may include determining strain on the structure using a plurality of gauges positioned on the structure. The method may also include detecting a parameter of the structure with a plurality of sensors positioned on the structure. Further, the method includes converting the detected parameter and the determined strain to proportional loads acting on the structure and transforming the proportional loads to coordinate system data associated with the structure. Based on the coordinate system data, the fatigue life of the structure may be estimated.
摘要:
A remote control providing the means for making adjustments to a plurality of electronic display screens. The remote control provides the means to control a selected group or groups from the array of electronic displays or of the entire array of multiple electronic display screens. The commands being sent would include but are not limited to brightness up and down, contrast up and down, input source, color intensity, aspect ratio, ‘on/off’ features and other commands or adjustments applicable to an array of multiple electronic displays. The adjustments can be made simultaneously or in a desired sequence. The remote control transmits information via infra-red, radio frequency or other wireless means to a remote sensor with a microprocessor located within the electronic display or to a central microprocessor that serves to further the signal to each electronic display.
摘要:
An anti-lock braking system (ABS) calculates driven wheel speed without any sensors on the driven axle assembly. A powertrain control module (PCM) receives signals from an output shaft speed (OSS) sensor and adds the speed and axle ratio information to a control network bus. Access to the CAN bus is provided to enable calculation of the rear wheel speed based on such information so that ABS may implement anti-lock braking functionality by taking into account such information.

A method for controlling a powertrain of a vehicle is provided for traction control. The method comprises controlling wheel slip to a first amount, the first amount independent of a driver requested output; and controlling the wheel slip to a second amount when a vehicle speed is less than a threshold for a first duration, the second amount based on the driver requested output.

A method is provided for controlling a powertrain of a vehicle comprising wheels, and an accelerator pedal actuated by a driver. The method comprises controlling wheel slip to a first amount during a first road condition, the first amount independent of a driver requested output; and controlling the wheel slip to a second amount during a second road condition, the second amount based on the driver requested output, the second road condition having higher friction than the first road condition.

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:
Methods and systems for constructing a load history database for a structure is disclosed. In one embodiment, a method is disclosed that may include detecting a measurable parameter on the structure utilizing a sensor positioned on the structure and determining a value of external loads acting upon the structure based on the detected parameter. Further, the method may include evaluating the value of the external loads against a pre-established factor. Based on the evaluation, the value of the external loads are selectively stored in the load history database.
