Abstract: A directional input device includes a base and a head selectively connected to the base by a twist-lock mechanism. The head and base define a center axis of the directional input device. The twist-lock mechanism includes a post oriented in an axial direction of the center axis, at least one flange protruding in a radial direction from the post, a receiver configured to receive the post and the flange, and an angularly oriented channel in the receiver configured to allow the post and flange to rotate into the channel and capture the flange in the axial direction.

Abstract: In one embodiment there is provided an aquatic toy configured for movement under water. The aquatic toy employs sensors to automatically turn on when placed in water and further employs a timing circuit to automatically turn the toy off after a predetermined amount of time. The aquatic toy further includes a shock sensor to monitor movement of the toy when in water and after the timer expires. Movement such as tapping on the tank, splashing the water, or physical movement of the toy will turn on the toy and re-activate the timer. However, the sensors can further detect when the toy is dry to ensure the shock sensor is only active when the sensor is wet.
