    摘要: The computational resources of a digital power meter can be reduced by utilizing an interrupt requested in anticipation of interrupt latency to perform real-time tasks, an approximation of a root mean square load current at an earlier time to compensate for a phase shift between the load current and the current transducer output, and an amplitude that is neither zero nor maximum to distinguish the cycles of a harmonically distorted waveform.

    摘要: Methods and apparatus for vibration-generated movement and manipulation, such as transportation, orientation, loading or sorting of materials are provided. At least one electromagnetic coil is disposed to act in a horizontal plane, and another electromagnetic coil may be disposed to act in a vertical plane, imparting two-dimensional vibration to a generally horizontal vibratory surface. Apparatus vibrationally transports parts across a surface while concurrently orienting and sorting them. Reversibility of transport direction is also provided.

    摘要: A system (100) performs concurrent testing and lead verification of an electronic component (104) having two leads (126 and 128). The system includes circuitry (114 and 116) for determining a sum of amounts of contact resistances between first (132) and second (134) probes and one of the leads by producing a current (I.sub.1) that propagates through the first probe, the lead of the component, and the second probe. The sum of the contact resistances is proportional to the difference in voltage between the leads. If the difference exceeds a limit, then the sum of the amount of contact resistances is excessive. The system also includes circuitry (110) for determining a value of a parameter of the component while the sum of the amounts of contact resistances is being determined. The circuit for determining the sum of the contract resistances and the circuitry for determining the value of the parameter are electrically isolated from each other so that they do not influence each other.
