Abstract: This invention is a Telescoping Handle Doorstop Wedge, the light-weight high-quality aluminum handle of which can be closed-down or extended-up, stopping at any length between 9 inches and 38 inches. When extended, the Telescoping Handle Doorstop Wedge can be lengthened and custom adjusted to any person's comfortable/practical operating height, thus making it easy for the permanently-attached non-marking, non-skid, wide-footprint, oversized rubber doorstop wedge to be effortlessly inserted into or retracted from the space between the bottom edge of a hinged door and the floor below. The invention's non-stoop, no-muscle-strain benefits are obvious for persons such as those who are disabled, infirmed and elderly, or for other persons who cannot or simply do not prefer to bend or stoop so as to painlessly, effectively and accurately insert or release a doorstop wedge.

Abstract: A hitch assembly including a hitch ball and a socket is disclosed. The socket is generally cylindrical and has an inner diameter being at least as large as an outer diameter of a hitch ball mounting portion. A pin receiving groove is formed in a vertical direction on the hitch ball. Additionally, at least one engagement groove encircles the diameter of the hitch ball mounting portion. The hitch ball mounting portion also includes a flattened portion. The assembly also includes a retaining pin configured for sliding in the pin receiving groove. The socket has a bottom plate including a through hole configured to receive the retaining pin when the hitch ball has been rotated so as to allow the retaining pin to slide through the through hole.

Abstract: A method and apparatus facilitate secure communication between a controller and a signaling network. The controller generates messages corresponding to a protocol of the signaling network and wraps them in a second protocol. The wrapped message is carried via a second network to a gateway that unwraps the message and provides it to the signaling network.
