Abstract: The present invention, in certain embodiments, is an apparatus to indicate the presence of an under-pressurized pneumatic tire for a vehicle, including, trailers, tractors, trucks or passenger vehicles. The apparatus comprises a housing, a cap, a shaft, a probe element, a bracket, an electrical switching element an electrically powered alarm. The housing is mounted next to the axle for the wheel of the vehicle. The cap is attached to the housing and has an aperture to receive the shaft. The shaft extends through the cap, and at one end, receives the probe element, and at the other end, holds the bracket upon which the electrical switching element is attached. When a tire loses air pressure, the height of the tire, as well as the vertical distance from the axle to the travelling surface, decreases; as the vertical distance decreases, the probe element contacts the travelling surface and rotates the shaft, bracket and electrical switch.

Abstract: The present invention, in certain embodiments, is an exterior-wall-mounted accessory outlet unit for a recreational vehicle, motor home, travel trailer or mobile home. The apparatus includes a housing and a mounting plate. The housing is adapted to be positioned through the exterior wall of a recreational vehicle, motor home, travel trailer or mobile home. The housing includes a mounting lip and side walls, which form an interior space, and a receiving ridge. The mounting plate is shaped to fit into the receiving ridge of the housing, such that the outwardly-facing planar surface is generally parallel to a plane defined by the exterior wall of a recreational vehicle, motor home, travel trailer or mobile home. Within the mounting plate is at least one aperture for accommodating at least one electrical power accessory outlet, at least one coaxial cable mount, at least one modular telephone connector and at least one exterior speaker outlet.

Abstract: The present invention, in certain embodiments, a portable structure for supporting infants for the purpose of training and assisting infants to walk. The structure comprises a frame, generally U-shaped at the top with at least one J-shaped leg element being attached to the frame, with the J-shaped leg elements being parallel to each other, and with the J-shaped leg elements being padded. The frame may be made of a light-weight material, such as aluminum or steel tubing, wood or plastic, and the padding is made of a flexible, yet durable impact-absorbing material. The structure may further include a wheeled extension member attached to either the top of the frame or to one or more of the J-shaped leg elements.
