A method is provided for an equalization strategy for compensating channel distortions in a dual-polarization optical transport system wherein the received signal includes a complex signal of a first transmitted polarization component and a complex signal of a second transmitted polarization component. In a first step, a blind self recovery mode used a blind adaptation algorithm in calculating and modifying multiple complex equalizer transfer function coefficients to enables recovery of only the complex signal of the first transmitted polarization component. In a second step, equalization is performed in a training mode for recovery of the complex signals of the first and second transmitted polarization components. In a third step, equalization is performed in a data directed mode. The method is suited for a digital signal processing implementation in a coherent receiver.

A touch-sensitive apparatus is configured to define a touch surface on a panel by propagating diverging energy beams (e.g. of radiation) across the touch surface inside the panel. Two rows (20A, 20B) of components (2, 3) of a first type that emits energy as a diverging beam and a second type that detects energy are functionally connected to the panel at opposite ends of the touch surface. The rows (20A, 20B) are defined by consecutive component blocks (B) that each contain only components (2, 3) of one type and are defined by type and number of included components. Each row (20A, 20B) comprises a respective sequence (S) of two component blocks (B) of different types and is defined by systematically repeating the sequence (S) along the respective opposite end. To achieve an improved spatial resolution of the touch-sensitive apparatus for a given number of components, at least one of the sequences (S) is selected to consist of two component blocks (B) with different number of components, and the sequences (S) are selected such that at least one component block (B) differs between the sequences (S).

The present invention relates to an electrical energy regulator system for a power supply bus, the system including:an electrical energy storage unit,a solar generator having a plurality of cells,a system for regulating the bus power supply voltage adapted to impose on each cell one of the following three states:a first state in which the bus is supplied with current,a second state in which the storage unit (BAT) is supplied with current, anda third state in which the cell is shunted,the cells being divided by the bus voltage regulator system into:a first group in which at least one cell supplies power to the bus and one cell is assigned to regulation of the voltage of the bus and is in its first state only when maintaining a nominal bus voltage requires a top-up of current, anda second group in which at least one cell is either in a second state or in a third state, as a function of a required charging current of the storage unit, the number of cells in the second state being a function of the required charging current.The system further includes a system means for regulating the charging of the storage unit which assign at least one cell of the second group to supplying power to the storage unit (BAT) and one cell of the second group to regulating the voltage of the storage unit, the storage unit charging voltage regulator cell being in its second state only when maintaining a nominal charging voltage requires a top-up of current.
