Abstract: A holder apparatus for air fresheners may include, for example, a base having a front side and a back side; a front-side holding mechanism; and a back-side mounting mechanism. The front-side holding mechanism may be configured to hold an air freshener in a manner such that the air freshener is exposed on at least one side in an amount greater than about 50% of the surface area of the at least one side. The back-side mounting mechanism may be configured to mount the base onto a mounting surface.

Abstract: A differential gear assembly is disclosed. In some embodiments, the differential gear assembly includes a first sun gear and a second sun gear coaxially aligned with each other; a first set of planetary gears in mating engagement with the first sun gear; and a second set of planetary gears in mating engagement with the second sun gear. The first and second sets of planetary gears can be in mating engagement with each other. In some embodiments, the differential gear assembly also includes a first set of friction members, each of which faces a respective one of axial ends of the first set of planetary gears; and a second set of friction members, each of which faces a respective one of axial ends of the second set of planetary gears.
