Abstract: A battery charging method includes: determining whether a current charging cycle satisfies a floating charging condition when a first condition is satisfied, the first condition being that in a case where battery capacity is greater than a set capacity, a duration of continuous charging is greater than a set threshold; and charging using a set floating charging mode after determining that the current charging cycle satisfies the floating charging condition. As such, the battery capacity during the charging process is detected in real time. In a case where the battery capacity is greater than the set capacity, the duration of continuous charging is greater than the set threshold and the current charging cycle satisfies the floating charging condition, the floating charging mode is used in time, such that batteries are prevented from dangerous situations such as bulging, expansion and explosion, and the safety of battery charging is improved.

Abstract: A twister includes a base unit, a shaft, and a foot support. The shaft extends substantially perpendicularly from the base unit and defines a pivot axis. The foot support is movably mounted to the shaft above the base unit. The foot support may provide one of a single vertical movement, a single pivotal movement, and a combination of vertical and pivotal movement depending upon a user's exercise on the foot support.
