Abstract: An apparatus to solve Sudoku puzzles, wherein each one of the 81 single-squares has nine sub-area squares, each having one of the 1 through 9 digits, with all digits set to ‘at-display’ at start, and by selectively setting to ‘no-display’ 8 digits at each one of the initially given number's single-square location of a given puzzle so as to set up the puzzle, followed by logically setting other digits to ‘no-display’ at other single-squares needing solutions, the process of ‘no-display’ setting can be continued until all the single-squares have for each one only one digit ‘at-display’ as per Sudoku rules.

Abstract: A rapid air transportation system for humans, animals, materials or facilities, comprises of rapid coupling of a carriage on land to the tether of a hovering aircraft using quick coupling methods and rapid de-coupling of the same at the end of transportation and landing of the carriage, without landing the aircraft.

Abstract: Paperimage is a lightweight, notebook size, portable electronic product, with one or more display screens, and shaped in the form of a foldable notebook or a tablet. It has multiple connecting ports of multiple types so that multiple compatible equipments can be connected to it to transmit and receive electronic data among the connected equipments. Its functions, at minimum, are displaying, receiving, transmitting and organizing of readable text and graphic documents in electronic form. Walletimage is a miniature version of Paperimage, suited to be carried in the pocket of one's clothing. Its primary function is to carry electronically, information of items normally in a wallet, such as credit cards, business cards, purchase receipts, et cetera. It can also receive and store data that is normally meant to be displayed by Paperimage, as well as transmit data to other compatible equipments.

Abstract: A nested two-piece Plant Potting Assembly consists of a strong and durable Outer Pot that is substantially permanently installed below ground level such that its open side rim is substantially at ground level and rest of its body is below the ground level. The easily removable Inner Pot contains soil and plants. Multiples of such assemblies installed below ground level in desired patterns present a pleasing and easily serviceable garden.

Abstract: A specialized bed is described, FIGS. 2 and 3, that will prevent bedsores, heal existing bedsores, with no repositioning of patient required. With modifications it will be an effective massager, FIGS. 14 and 15. The following is a description for Bedsores Therapy. The electro-mechanically powered bed, designed for resting of a living body that has limited or no capability of motion by self, has its resting area composed of movable Bed Elements, FIGS. 5 and 6. The sequential lowering of these Bed Elements from contact with the body for sufficient length of time reestablishes blood circulation near skin in the regions that had been starved of blood. Down and up motion of the Bed Elements is created by Gear Motor Drive 30 which rotates two Camshaft assemblies 28L and 28R. A series of Cams 82, arranged with gradual phase shift, give the down and up movements to the Bed Elements in a desired sequential and cyclical manner.
