Abstract: Method of driving a liquid crystal display by supplying selectable column voltages Gj(t) from a predetermined number of column voltages levels, selection signals to groups of mutually orthogonal p rows (p?1) for the duration of a row selection time p×nfrc during a supcrframe nfrc to generate grey scales. The column voltage is calculated depending on the grey scales of the p pixels in a column and on the mutually orthogonal selection signals Fi for the corresponding group of rows. The row selection time is subdivided in npwm sub selection time. The grey scales are coded in grey scale tables having nfrc phases with npwm. The superframes grey scales are generated using phase mixing. The change in the column voltage level defines a transition. The column voltage has always less transitions per row selection time than the number npwm of sub selection time of the row selection time.

Abstract: A variety of edge-detection related devices, methods and systems are implemented in various fashions. One implementation is directed to an edge detector circuit (100) for detecting an edge of an input signal and producing an output level-sensitive signal that is synchronous to a clock signal having an active edge corresponding to a transition from a first-signal level to a second-signal level. A first flip-flop (102) has the input signal as a clock input and produces an internal level-sensitive signal and is reset by the output level-sensitive signal. Logic passes (104) the level-sensitive signal when the clock signal is at the second-signal level and blocks the internal level-sensitive signal when the clock signal is at the first-signal level. A second flip-flop (106) is set by the passed internal level-sensitive signal to produce the output level-sensitive signal. The second flip-flop (106) is cleared in response to the output level-sensitive signal, a reset input and the clock signal.

The optimal coil (130) may be selected by measuring the position angle of the transmitter (100) and/or the receiver by making use of at least one inclinometer (132). For radio communication on the transmitter and/or on the receiver this coil (130) is selected, whose orientation is maximally parallel with the orientation of the corresponding coil on the other side of the radio communication link.
