Abstract: An energy conversion arrangement configured to convert chemical energy into electrical energy. The energy conversion arrangement comprises plural cell groups 30, 32, 34, 36, each cell group being configured to convert chemical energy into electrical energy. The energy conversion arrangement also comprises at least one measurement arrangement 38, 40, 42, 44, 46 configured to make measurements at each of the plural cell groups 30, 32, 34, 36. Each energy conversion arrangement is configured to determine a condition of at least one of: each of the plural cell groups; and the energy conversion arrangement. The condition is determined in dependence on the measurements made at each cell group and a model of each cell group.

Abstract: An energy conversion arrangement configured to convert chemical energy into electrical energy. The energy conversion arrangement comprises plural cell groups (30, 32, 34, 36), each cell group being configured to convert chemical energy into electrical energy. The energy conversion arrangement also comprises at least one measurement arrangement (38,40,42,44,46) configured to make measurements at each of the plural cell groups (30, 32, 34, 36). Each energy conversion arrangement is configured to determine a condition of at least one of: each of the plural cell groups; and the energy conversion arrangement. The condition is determined in dependence on the measurements made at each cell group and a model of each cell group.

Abstract: A method of locating and tracking a cellular terminal (1) is described. The method comprises the detection of one or more handover events that take place when the cellular terminal (1) moves between transmission regions (3) of a cellular terminal network provider. Information regarding the handover events is recorded within a database (4) so that the location of the cellular terminal (1) can be calculated. The calculation of the location of the cellular terminal (1) is achieved by either comparing the information with previously stored data or by extracting information regarding the location and geometry of the individual transmissions regions (3) such that a handover region (9) can be calculated. The precise location and area of the handover regions (9) takes account of various factors including power, time of flight of the transmitted signals and timing synchronization within transmission regions (3) and the effects of shadowing of the transmitted signals.

Abstract: A method for detecting the location of a user terminal in a telecommunications network comprising: receiving network information from the terminal and using the signal from the terminal and a netlist (4C) to determine or predict the location of the terminal. The netlist (4C) can be represented as a state diagram with interconnections being associated with probabilities. As a simple example, the probability of moving from cell A to cell B is 0.7 (0.14+0.56). However, if the previous cell was D, the probability of moving from cell A to cell B is reduced to 0.56.
