Abstract: An agitator for mixing solutions in a bottle is described. The agitator is comprised of a handle portion and a whisk portion. The agitator may have a helical-shape to encourage spinning of the agitator as liquid flows past the agitator. The whisk may be flat-bottomed and formed of a flexible material, such that when the whisk portion comes into contact with the bottom of the bottle, the whisking members splay outwardly.

Abstract: An isolation apparatus includes isolation circuitry that includes multiple semiconductor switches arranged electrically in parallel to isolate, from an electrical system, a plurality of battery cells of a battery capable of providing high levels of current. The apparatus includes a microcontroller operatively coupled to the isolation circuitry, wherein the battery cells are isolated from the electrical system to which the battery is connected when the microcontroller switches off the multiple semiconductor switches. The apparatus provides cell-balancing, circuit isolation, trace matching, split columns, heat-tied use of materials and slow-speed switching to provide safety through isolation, equalization and stress reduction.
