Abstract: Methods and systems for determining a user's steps in portable device include deriving amplitudes from raw sensor data; comparing the amplitudes to an amplitude threshold, and counting a step when one of the amplitudes exceeds the amplitude threshold to obtain a step count; determining a current gait type based on the step count; dynamically adjusting the amplitude threshold in order to reduce effects of swinging movements and false steps; and applying a post filter to the step count based on time between steps and a minimum number of prior consecutive steps to derive a filtered step count that reduces false readings due to short bursts of rapid movement by the user.

Abstract: A method and apparatus for adjusting the format of a table. The table comprises a column with a first, second, third, and fourth edges. The method comprises selecting a first edge of the column, the first edge residing in a first position on a page. Then, the first edge is moved to a second position on a page. Text of the column is reflowed to fit within the first, second, third, and fourth edges. The means for selecting comprises a mouse, in a preferred embodiment, and a means for selecting comprises a selection button on the mouse.
