Abstract: A system includes a body comprising a conduction path, and first and second modules disposed along, and movable relative to, the body, each of the first and second modules including an energy storage device, a terminal, and a power management unit coupling the energy storage device and the terminal. The terminal of each of the first and second modules is capacitively coupled with the conduction path for bidirectional power transfer between the first and second modules via the conduction path.

Abstract: A method for graphical representation of a train of ECG complexes having an R wave and a T-P interval and having variable isoelectric baselines. The method involves aligning the complexes in terms of signal amplitude by obtaining a baseline, thereby to provide a graphical representation of said train of ECG complexes; and aligning said complexes temporally using corresponding predetermined points.

Abstract: Apparatus for graphical representation of a train of ECG complexes each including an R wave and a T-P interval and having variable isoelectric levels. The apparatus includes an isoelectric alignment unit for aligning the complexes in terms of isoelectric level by aligning respective T-P intervals, thereby to provide a graphical representation of the train of ECG complexes; and a temporal alignment unit for aligning the complexes temporally using a selected point on the respective R waves. The aligned units are superimposed to provide a distribution of a normalized ECG signal over a series of pulses or heartbeats.

Abstract: Dictionary based data compression apparatus comprising: a library of static dictionaries each optimized for a different data type, a data type determiner operable to scan incoming data and determine a data type thereof, a selector for selecting a static dictionary corresponding to said determined data type and a compressor for compressing said incoming data using said selected dictionary. The apparatus is useful in providing efficient compression of relatively short data packets having undefined contents as may be expected in a network switch.
