摘要： A circuit for extracting a connected component feature from an input image includes an input stage, a counting stage, a bit-preparing stage, and a bit-output stage. The input stage receives a bit pattern and detects a connected component in the bit pattern. The counting stage counts the number of connected components detected in the input stage and generates a current representing that number. The bit-preparing stage generates more than one current as a basis for information including more than one bit, based on the current generated in the counting stage, so that the information uniquely represents the number of connected components. The bit-output stage converts the currents generated in the bit-preparing stage into a digital output corresponding to the information.

摘要： A winner-take-all (WTA) circuit apparatus for comparing two current inputs from a WTA circuit to a threshold current to create a reject signal, to assist in the decision criteria of a winner-take-all network. The circuit compares the two input currents from the WTA circuit by using NMOS transistors which perform electrical mathematical functions by manipulating the currents. The end result is that the difference of the two currents is compared with a reference current and a voltage level is outputted. The reference current is adjustable, and the invention also provides a WTA circuit with weighted inputs, and the ability to select between a 1-WTA, and a 2-WTA configuration. The invention therefore solves the problems of prior art by being capable of properly selecting current levels or rejecting current levels which are too close in value, with a voltage reject signal.

摘要： Method, system, and programs for calibrating battery pack voltage are disclosed. A negative terminal voltage of a cell is changed from a first to a second negative terminal voltage so that a cell voltage is changed from a first to a second output voltage. A positive terminal voltage of the cell is maintained at a substantially constant level. A differential-mode calibration parameter is calculated based on a difference between the first and second output voltages and a difference between the first and second negative terminal voltages. The negative terminal voltage of the cell is then changed from the first to second negative terminal voltage so that the positive terminal voltage of the cell is changed from a first to a second positive terminal voltage and the output voltage is changed from a third to a fourth output voltage. The cell voltage is maintained at a substantially constant value. A common-mode calibration parameter is calculated based on the differential-mode calibration parameter and a difference between the third and fourth output voltages and a difference between the first and second positive terminal voltages.
