    • In one embodiment, a current source circuit having a reference resistor produces first, second and third bias currents that vary with manufacturing variances of the current compensation resistor. An input amplification stage includes a transconductance stage biased by the first bias current, a first transimpedance amplifier (TIA) biased by the second bias current, and a first feedback resistor coupled between the first TIA's input and output. The input of the first TIA is coupled to an output of the transconductance stage. An output amplification stage is biased by the third bias current and has an input coupled to an output of the first TIA. A second feedback resistor is coupled between the output of the output amplification stage and the input of the transconductance stage. The reference resistor and first and second feedback resistors are formed using a common manufacturing process.

    • A method and a current sensor for measuring a current in a conductor. The sensor comprises a non-magnetic, flexible core member having a first end and a second end. A locking head having a channel therethrough is coupled to the first end of the core member. A first sensor conductor winding layer is mounted on the core member. Wherein the second end releasably engages the locking thread in the channel and adjustably configures the core member to surround the conductor as the second end is moved through the channel. In another embodiment the current sensor includes a locking tang within the channel and a plurality of sought tooth members on a portion of the core member and configured to selectively engage the locking tang as the second end of the core member is moved through the channel.

    • A method and system for determining regression functions from a computer data input using K-Harmonic Means (KHM) regression clustering (RC) and comprising the steps of: (1) selecting K regression functions ƒ1, . . . , ƒK; (2) associating an i-th data point from the dataset with a k-th regression function using a soft membership function; (3) providing a weighting to each data point using a weighting function to determine the data point's participation in calculating a residue error; (4) calculating the residue error between the weighted i-th data point and its associated regression function; and, (5) iterating to minimize the total residue error. Such can be applied in data mining, economics prediction tools, marketing campaigns, device calibrations, visual image segmentation, and other complex distributions of real-world data.
