Vehicle weighing in motion apparatus and method |
March 26, 1991 |
| A weighing in motion (WIM) apparatus and method in which scale platforms are provided exhibiting a high rigidity selected to achieve a relatively high natural frequency response characteristic. These platforms are combined with instrumentation wherein load cell derived signal outputs are |

Weigh-in-motion scale |
September 18, 1990 |
| Apparatus for weighing vehicles in motion includes a base to be anchored to a roadbed below ground level in the path of moving vehicles and a pair of scale platforms mounted on the base for receiving the wheels on the opposite sides of the moving vehicles. Load cells are provided between |

Enclosed moment-insensitive load cell |
September 18, 1990 |
| A dual beam moment-insensitive load cell is hermetically sealed in a bellows or partial-bellows enclosure. The enclosure may have convolutions over substantially its entire length which permits it to flex easily in the direction of load cell bending. The enclosure is made resistant to |

Load cell mounting for rotational control |
September 11, 1990 |
| Load cells incorporating rocker pin configured columnar central structures within a weighing system have the attribute of self-erecting upon being displaced from a vertical orientation due to dynamic transverse loading effects, as may be occasioned by vehicle movements onto a scale. The |

Planar load cell |
February 6, 1990 |
| A load cell stamped from a single plate includes a pair of strain gauges mounted on each lateral edge of the plate and a slot extending between laterally opposite strain gauges. The load cell so formed can be widened to provide increased torsional stiffness and resistance to off-center |

Load cell |
March 28, 1989 |
| A digital load cell includes a rocker pin, guided beam, torsion ring or other counterforce, a circuit board mounted on the counterforce and an enclosure sealing the circuit board and all but the load bearing surfaces of the counterforce. The circuit board includes an A/D converter and a |

Compensated multiple load cell scale |
February 14, 1989 |
| Multiple digital load cells forming one or more weighing scales are connected together and to a common master controller in a local area network. The digital load cells are polled by and provide weight readings to the master controller. The weight readings are combined with a load po |

Digital load shift compensation |
January 24, 1989 |
| A digital weighing scale is compensated for the effects of off-center loading by determining the position of the load and calculating a corrected weight value according to such position. Position sensing transducers are mounted on the load cell to provide information regarding the po |
