A method of testing the base station comprises detecting at the transceiver arrangement the signal strengths of a test signal received via the beams; comparing and/or correlating the said signal strengths detected at the transceiver arrangement; and using the results of the comparisons and/or correlations to determine the configuration of the antenna arrangement and transceiver arrangement and/or to detect faults. The comparison of average signal strengths can be used to detect cabling faults, and beam errors. The correlation of un-averaged signal strengths can be used to determine which beams have the same polarization. Beam pointing directions and the allocation of antennas to sectors can be determined by monitoring handovers of mobiles moving between cells. Frequencies may be allocated to sectors according to a frequency re-use scheme.

Abstract: A system and method for stimulating a brain structure of a patient for treating a condition. A stimulating electrode is inserted into a brain structure of the patient. After inserting the stimulating electrode into a brain structure of the patient, the patient is prompted with a task. When the task is completed by the patient, the stimulating electrode is used to transmit a stimulating signal into the brain structure of the patient. In an alternative implementation, the patient's brain is monitored for the existence of a particular condition. When the condition is detected, the stimulating electrode is used to transmit a stimulating signal into the brain structure of the patient.

Abstract: A computerized system and method facilitates the collection, calculation, and analysis of supplier capacity data. Using portal technology, communications between the manufacturer and suppliers related to capacity data are facilitated. The system and method accommodate numerous supplier manufacturing processes and their unique configurations so that consistent “standard’ and “maximum” capacity values may be calculated. The portal supports data entry to quickly, efficiently, and accurately identify capacity constraints at the process and part number levels, create solutions, and monitor the implementation of solutions to increase capacity. Using dynamic calculation logic, fluctuating demand values for parts are considered in determining probable capacity values. The impact of various investments on production capacity may also be assessed. The manufacturer may further use capacity constraint data to adjust production to sales or market changes and to align production with capacity.
