Abstract: A personal regulator or device having special covers and a plurality of interior panels or pages containing various hinged structures. The hinging structures are precision expandable hinges which permit portions of consecutive panels to be functionally interactive and viewed simultaneously and/or to permit viewing of different portions of interior panels while viewing two charts attached to the device enclosures. The precision expandable hinging structures provide and allow for a plurality of charts to be viewed simultaneously and accurately registered with each other without the need of repeatedly turning between pages or panels.

Abstract: A booklet having a plurality of interior pages containing hinging structures. The hinging structures permit portions of consecutive pages to be viewed simultaneously or to permit viewing of different portions of an interior page while viewing two charts attached to the booklet covers. The hinging structures allow multiple time periods or plural charts to be viewed simultaneously without the need of repeatedly turning between pages.

Abstract: A calender structure includes linking apparatus for displaying, in a linked and continuing fashion, time sequences shown on separate pages thereof. The individual pages are provided with specific hinging structures to permit simultaneous viewing of the last portion of one month and the first portion of a next month, for example, so that a continuing display is provided for linked time sequences notwithstanding the fact that such sequences are provided on separate pages. A single hinging operation results in the continuing display, thus avoiding the necessity for repeatedly turning between two calander pages at periods approaching an end of the month.

Abstract: This invention is a method for forming an antenna reflector and housing f a plastic material, rather than from metal or a glass/cloth laminate. The method comprises the steps of scribing a grid structure on a plastic sheet; vacuum or gavity forming the plastic sheet and trimming it to size; coating the plastic sheet with a conductive metal such as copper; and then removing the excess copper from the antenna. Alternatively, a printing and etching technique can be used in substitution of the scribing coating steps.
