Abstract: A method for determining a position of a mobile terminal in a mobile network including a plurality of base stations (BSs) and repeaters (REs) is provided. In the method, a plurality of BS signal data is received, and the BS signal data includes propagation delay time data and is transmitted from the BSs to the mobile terminal. The BSs or the REs corresponding to the respective BS signal data is determined on the basis of the propagation delay time data. Vector data related to the BSs or REs is generated on the basis of geographic data corresponding to the determined BSs and REs. Position data of the mobile terminal is generated according to the generated vector data. In the step of generating the vector data, a progression order of vectors related to the BSs and the REs is determined according to the BS signal data. The vectors are sequentially determined according to the determined vector progression order. The vectors starts at a BS or a RE currently communicating with the mobile terminal. The present invention makes it possible to utilize the existing BS signal data as they are, to determine a position of a mobile terminal more accurately, and to continuously provide accurate position data regardless of a change in a mobile network.

Abstract: A method for counteracting increases in resistivity encountered when Indium Oxide resistive layers (18) are subjected to high temperature annealing steps during semiconductor device fabrication. The method utilizes a recovery annealing step which returns the Indium Oxide layer (18) to its original resistivity after a high temperature annealing step has caused the resistivity to increase. The recovery anneal comprises heating the resistive layer (18) to a temperature between 100 DEG C and 300 DEG C for a period of time that depends on the annealing temperature. The recovery is observed even when the Indium Oxide layer is sealed under a dielectric layer (24).

A memory according to the present invention includes a ferroelectric capacitor, a charge source and a read circuit. The charge source receives a data value to be stored in the ferroelectric capacitor. The charge source converts the data value to a remanent charge to be stored in the ferroelectric capacitor and causes that remanent charge to be stored in the ferroelectric capacitor. The read circuit determines a charge stored in the ferroelectric capacitor. The data value has more than three distinct possible states, and the determined charge has more than three determined values. The memory also includes a reset circuit that causes the ferroelectric capacitor to enter a predetermined known reference state of polarization.
