Abstract: A switchable finger follower for a valve train of an internal combustion engine includes an outer and an inner lever, which at a first longitudinal end run pivotably relative to one another via respective bores on a common shaft. At this longitudinal end, the finger follower has a gas-exchange valve contact face on an underside. The outer lever has a pivot bearing on the underside at a further longitudinal end, and at least the inner lever has a cam running face on an upper side. The inner and outer levers are connectable to one another via at least one coupling slide, which spans a separation area between the levers. The outer and inner levers are braced relative to one another via a cam return spring, and the shaft is connected to the bore of the outer lever by an interference fit.

Abstract: A spa assembly includes a base pan; a frame assembly; and a spa shell supported on the base pan and the frame assembly. The spa shell includes a bottom and at least one side defining an open internal volume, an interior surface oriented toward the open internal volume, an opposing exterior surface, and a rim surrounding the at least one side, the rim defining an internal cavity. The exterior surface of the bottom of the spa shell has a foam material applied thereon. The foam material applied to the bottom of the spa shell and the base pan comprise corresponding interlocking features that align the spa shell within the base pan. The internal cavity of the rim has the foam material applied thereto. The foam material in the rim has a groove formed therein, the groove being configured to receive the frame assembly.

Abstract: A spa can include one or more variable features or functions that can be controlled by a user using a gesture recognition sensor. The gesture recognition sensor can be located proximate to the spa and optionally out of the normal range of motion of a user in a basin of the spa. Predetermined gestures detected by gesture recognition sensor can be interpreted as a command to alter a predetermined feature or function of the spa. Also disclosed is a method of controlling one or more variable features or functions of the spa using the gesture recognition sensor.
