Abstract: An infant swing includes a base, a support coupled to the base, an arm coupled to and movable relative to the support, and a seat portion coupled to the arm. A drive system is coupled to the arm and moves the arm relative to the base. An actuator is connected to the drive system, and is located so that a user can engage the actuator with the user's foot to control the drive system.

Abstract: An electronic learning/teaching device operates with and without a printed sheet element having an arrangement of selectable content by means of a user responsive sensor array beneath a surface configured to receive the element. The sensor array is formed by cross-points of two sets of crossing conductive lines, one set being driven sequentially with a radio frequency square wave and the other set being sampled sequentially though a high impedance amplifier connection with an asynchronous detection circuit. Where more than one cross-point location is user activated, algorithms are used to identify one cross-point sensor location as the user activated selection.

Abstract: An apparatus includes a support frame, a resilient member, a seat, and a retainer. The resilient member has a first end portion configured to be coupled to the support frame and a second end portion, opposite from the first end portion. The seat is configured to be coupled to the second end portion such that the seat is suspended from the support frame by the resilient member. At least one of the first end portion and the second end portion includes multiple sleeves, each defining an opening therein. A portion of the retainer is configured to be disposed within a first one of the sleeves and coupled to at least one of the seat and the support frame such that a position of the seat relative to the support frame is adjustable by disposing the portion of the retainer within a second one of the sleeves.

Abstract: A track section includes a body having a coupling portion. In one embodiment, the coupling portion includes a projection extends outwardly from the coupling portion and a recess extending inwardly into the coupling portion. In one embodiment, the recess extends downwardly through the coupling portion. In another embodiment, the recess extends from an upper surface of the body to a lower surface of the body.
