摘要： During transfer of a material by a hydraulic excavator, load computing means periodically computes the weight of the material in a bucket of the excavator. Average value computing means computes an average value of weights of the material including a currently computed weight and a predetermined number of weights computed prior to the currently computed weight (M6), and standard deviation computing means computes, based on the average value, a standard deviation of the weights of the material (M7). True load value determining means selects a minimum standard deviation from among the standard deviations computed by the standard deviation computing means from the start of the transfer of the material to a different location until the end of the transfer of same, and judges the average value based on which the minimum standard deviation was computed, to be a true value of the weight of the material (M10, M11).

摘要： Disclosed herein is a method and system for calibrating line drive currents in systems that generate data signals by varying line drive currents and that interpret the data signals by comparing them to one or more reference voltages. The calibration includes varying the line drive current at a transmitting component. At different line drive currents, a receiver reference voltage is varied while the transmitting component transmits data to a receiving component. At each line drive current, the system records the highest and lowest receiver reference voltages at which data errors do not occur. The system then examines the recorded high and low receiver reference voltages to determine a desirable line drive current.

摘要： Methods and devices to measure threshold voltages of electro-mechanical systems devices are disclosed. The threshold voltages are determined based on which of multiple test voltages cause the devices to change states. State changes of the device are detected by monitoring integrated current or charge used to drive the test voltages.

摘要： A method to identify phase is presented. The method includes obtaining electrical parameters at a node and a substation of an electrical grid, processing the electrical parameters of the node and the substation into processed electrical parameters comprising at least one of a voltage harmonic amplitude, a current harmonic amplitude, a geometric harmonic modulated signal, and a noise pattern. The method further includes comparing the processed electrical parameters from the node and the substation and identifying phase information of the node with respect to the substation.
