    • The present invention provides an improved magnetic winding and method of calculating desired winding parameters (winding layer thickness, number of winding layers and number of turns per winding layer) for a winding in a magnetic component. The invention may be applied to general boundary conditions in a magnetic winding or component and considers relative phase displacement for sinusoidal and nonsinusoidal winding currents. Ratios of magnetic surface field intensities at corresponding inner and outer boundaries of one or more winding layer(s) are calculated, and considered with relative phase displacement to select magnetic winding configurations having desired or optimal power dissipation. In certain aspects, a normalized loss function f(H,R,B,Φ) is utilized to determine a preferred construction among a plurality of iteratively generated selections.

An acceleration sensor is disposed so that a sensitivity axis of the acceleration sensor is located in a range of 30° or smaller in a counterclockwise direction from the direction of 90° with respect to a longitudinal direction of a belt. A user of an electronic pedometer wears the electronic pedometer on his/her left wrist using the belt and starts processing for counting the number of steps by manipulating a manipulation portion, and also starts to walk, thereby starting counting the number of steps. The user checks the counted number of steps and the measured time period based on displayed contents on a step number display portion and a time display portion of a display portion.

    • In a positional information detecting device, a tone-burst signal propagating unit causes a tone-burst signal to propagate through a path. The tone-burst signal is composed of a continuous wave train, the continuous wave train including a plurality of cycles of a constant frequency. A detecting unit detects, at a predetermined position in the path, the tone-burst signal propagating through the path every one cycle of the tone-burst signal to measure a propagation delay time based on the detected signal. The propagation delay time represents a period for which the tone-burst signal has propagated through the path. A phase obtaining unit obtains a phase of the detected signal. A positional information obtaining unit obtains positional information associated with the predetermined position based on the measured propagation delay time and the obtained phase of the detected signal.

    • An apparatus and method for determining a linear position from a linear variable differential transformer (LVDT) including a primary coil driven by an excitation signal, and two secondary coils coupled to two correlated signals. The method includes converting the correlated signals to a digital estimate, for each of the correlated signals, and evaluating an amplitude of the correlated signals to determine the linear position. The process of converting the correlated signals comprises comparing the correlated signal to an analog feedback signal to generate a comparison result and incrementally adjusting the digital estimate in response to sampling the comparison result at an estimation frequency. The converting process also includes converting the digital estimate to the analog feedback signal, collecting a digital estimate history at a sample frequency that is a binary multiple of the excitation frequency, and analyzing the digital estimate history to determine the amplitude substantially near the excitation frequency.
