Abstract: The present invention provides an irrigation system with cheap humidity sensors and cheap automatic faucets preferably by using at the end nodes of the system low water pressure, so that much less force is needed to open and close the local waterway, and then either using simple electrical valves that do not require engines, or using for example mechanical sensors based on a bi-material of two or more materials which expand differently when they become wet, thus converting the difference of the expansion into convenient movement. Another possible variation, instead of mechanical sensors and valves, is to use for example a preferably synthetic material that tends to behave like a normal root preferably at the edge of each side channel, so that the “root” counter-balances the water supply and reaches equilibrium with it when the soil becomes wet enough, based preferably on asymmetric capillary materials.

Abstract: Broadband connections of end users to the Internet are becoming more and more common today, and the most common types of these fast connections are ADSL and Cable modems. These connections are typically still very slow compared to the speeds that are expected in the next few years and typically also highly asymmetric and allow typically 750-2000 Kbit per second (most typically 1500 Kbit) for the downlink and typically for example 96 Kbit or 128 Kbit per second for the uplink (although standard ADSL can in principle support up to 8 Mbit per second download speed and up to 800 Kbit per second upload speed), based on the assumption that most users download much more data than they upload.

Abstract: One of the biggest problems of efficiency in trains is the time wasted for boarding and letting off passengers at the stations. Since trains carry a very heavy mass, typically it can take a few minutes for the train to decelerate and come to a full stop and a few minutes to wait till all the passengers who want to get off or board the train finish boarding or exiting, and then again a few minutes to finish accelerating, and thus each stop at a station can typically slow down a train by 5-15 minutes. This is especially noticeable in fast trains, such as for example trains that go at 150 Mph or more, so that the same trip with the same type of train can take for example 3.5 hours when no or almost no stops are made on the way and 7.5 hours if the train stops at every station.

Abstract: Many areas in the world already suffer shortages of water, and others will suffer from it in the coming years. Therefore more efficient water sweetening is essential for our survival on this planet. The most commonly used water sweetening methods are: Reversed osmosis, distillation, electrodyalisis, and partial freezing. However, these methods suffer from low efficiency and high energy consumption, thus making them significantly more expensive than naturally obtained water. The present invention describes a system & method for efficient and low energy sweetening of water, based on borderline fast fluctuation between liquid to gaseous state and back, by using centrifugal forces to make water droplets fly at a high speed, so that they evaporate for a split second, the salt is separated, and they condense again. The present invention tries to make the process energy-efficient by enabling the use of lower speeds and smaller droplet sizes and solving various problems involved with that.

Abstract: When 3D viewing means become much more available and common, it will be very sad that the many great movies that exist today will be able to be viewed in 3D only through limited and partial software attempts to recreate the 3D info. Films today are not filmed in 3D due to various problems, and mainly since a normal stereo camera could be very problematic when filming modern films, since for example it does not behave properly when zooming in or out is used, and it can cause many problems when filming for example smaller scale models for some special effects. For example, a larger zoom requires a correspondingly larger distance between the lenses, so that for example if a car is photographed at a zoom factor of 1:10, the correct right-left disparity will be achieved only if the lenses move to an inter-ocular distance of for example 65 cm instead of the normal 6.5 cm.

Abstract: Both Laser printers and Inkjet printers have undergone many improvements in the last 10 years—mainly becoming faster and with better resolutions, and with prices going down all he time. However, one of the biggest limitations of all these types of printers has remained the same all the time: They print just on one side of the page. Although some printers on the market have an optional additional unit for mechanically flipping pages over, these units are typically cumbersome, expensive, and require extra space. Also, with mechanical flipping there is a higher chance for various malfunctions. Being able to efficiently print on both sides of the page can have many advantages: Saving paper costs, saving trees, saving office space or home space, being able to double the printing speed, being able to easily print eBooks, and more.

Abstract: As the Internet becomes faster and faster, with more and more demanding applications, and after the problems of faster routing and faster optic fibers are solved, the next main bottleneck will be the speed of the servers, and more specifically the speed (or rather the lack of it) of the hard-disks. Therefore, finding new revolutionary ways of making faster and larger hard-disks and/or larger RAM in the computer itself can help boost the computer and Internet world much faster into the future. The present invention tries to solve the problem of making much faster and much larger preferably non-volatile RAM by Using preferably 3-dimensional addressable preferably nano memory matrices instead of 2-dimensional, so that for example if instead of a 10×10 cm flat surface we have for example a 6×6×1 cm or 3×3×2 cm cube, we can get millions of Terabits, which are millions of times larger than current hard disks.

Abstract: Water faucets that allow the user to manually mix hot and cold water until the desired temperature is felt have existed for a very long time. However, it typically can take up to a few minutes of various manual adjustments to get the desired temperature. Since the early 80's there existed also the possibility of doing the mixing automatically until a certain preselected temperature is reached, for example by an electric faucet with a temperature sensor. However, these patents did not solve the problem of the waiting time until the cold water in the hot water pipe gets out, and they did not solve the problem of reaching the desired heat if the hot water source is not hot enough and/or reaching the desired coldness of the cold water source is not cold enough. Clearly a more sophisticated system is needed.
