Abstract: A system for and a method of providing an expandable home automation controller is disclosed which supports multiple numbers and multiple different types of data communications with both appliances and subsystems within the home as well as systems external to the home. The system is based upon a central processor, such as a microprocessor-based computer, and is connected by means of a data bus to control the various products and subsystems within a home or commercial building, such as lighting systems, security systems, various sensors, multiple external terminals, as well as to allow for the input of commands by a variety of means such as touchscreens, voice recognition systems, telephones, custom switches or any device capable of providing an input to a computer system. The system functions can be readily controlled by the user utilizing a high resolution graphics display and associated touchscreen interface.

Abstract: A two piece combination boat and luggage carrier having essentially identical half-sections and a plurality of removable seats is releasably joined along abutting sides to form a boat. In one embodiment, the halves are pivotally joined by hinges and the bottom of the boat is provided with raised ribs that mate with grooves formed in the bottom of the seats, the top of the seats being adapted to conform to the roof of an automobile, for transporting the luggage carrier. A third central section having inside dimensions greater than the external dimensions of the half-sections is secured between the two half-sections to provide a boat of larger capacity; the third, central section is adapted for nesting over the top of the closed carrier. In another embodiment, each half section is provided with a single male and female member in the abutting end which are adapted to receiving a pair of vertical blades to connect and secure the halves together to form the boat.

Abstract: A combination two-section boat and cargo carrier comprises first and second substantially identical sections. Each section has a substantially horizontal bottom surface, at least two generally vertical sidewalls, and a generally vertical connecting wall. The connecting wall is configured with a male connector which protrudes from the surface of the connecting wall in a direction generally normal to the plane of the connecting wall, and a complementary female connector which is recessed into the connecting wall in a direction generally normal to the plane of the connecting wall. The male and female connectors are symmetrically disposed from a vertical center line of the connecting wall, and adapted to mate with each other when the connecting walls of the first and second identical sections are placed in abutting relation to one another. A removable assembly blade connector is provided in order to join the male and female connectors, so as to form a boat.

Abstract: A first wall construction for a tokamak reactor is disclosed, comprising a series of hollow lobes, each having a pair of side wall portions with a curved end wall portion extending therebetween. Each lobe is adapted to withstand substantial pressure on the concave side of the curved end wall portion while withstanding substantial heat flux on the convex side. The curved end wall portion has a shape which is approximately cylindrical in curvature but differs from being circular in curvature by a substantial deviation, in that such curved end wall portion is flatter in curvature than a truly circular curvature by the amount of such deviation, such that the thermal stresses generated in the curved end wall portion by such heat flux are at least approximately balance or neutralized by the bending stresses generated in such curved end wall portion by such pressure. The curvature may correspond generally in shape to the flatter half of an ellipse.
