Abstract: The present invention provides a method and apparatus for the construction of a low-cost building structure through the synergistic composition of material, process, and structural design. In a first embodiment, a specially fashioned balloon, in the shape of a house, is used as a one-sided form, and is sprayed with a building material formulation. The building formulation may include: structural material, reinforcing material such as fibers to eliminate or minimize separate structural reinforcement, a gaseous bubble material (to provide thermal insulation), and other ingredients such as fillers, strengtheners, bulk-formers, accelerators, coloring agents and dryers. The structure can be created rapidly, and the balloon deflated and removed in minimum time, all by a few as 2 men. The low cost of the labor and materials and equipment used according to the present invention result in a more economical method of creating a building than any presently known method.

Abstract: A miniature electronic device, an example of which being an electronic watch, includes a printed circuit board which is mounted in a case and which has an aperture. A battery extends into the aperture forming a substantially coplanar assembly of exceptionally small thickness. The printed circuit board also features the use of circuit paths disposed on the peripheral edge to connect selected circuit paths which are disposed on upper and lower surface of the printed circuit board. An alternative embodiment of the printed circuit board features the use of a digit drives chip mounted directly on top of an integrated circuit watch clip with wire bonds leading from selected pads on the digit drives chip to selected pads on the integrated circuit watch chip and to selected circuit paths on the printed circuit board.

Abstract: A solid state touch switch is provided, in which, during use, a portion of the user's body, such as a finger, forms a portion of an electronic circuit to change the state of a solid state electronic device and thereby actuate the solid state touch switch. Alternative embodiments of the invention contemplate the use of various solid state electronic devices including metal-oxide semiconductor field-effect transistors (MOSFET'S) junction field effect transistors, silicon controlled rectifiers and NPN transistors. One application of the solid state touch switch is in a digital watch in which a user touches a contact pad located on the watch case and thereby turns the digital watch on for the display of time and date signals.
