Noise reduction sandwich panel, notably for an aircraft turbojet engine. In order to produce a noise reduction sandwich panel having a structure with two degrees of freedom, inserted separative components (20) are placed into the hexagonal cells (16) of the unique waffle core of the panel. More specifically, the separative components (20) have an substantially circular external peripheral edge, which allows them to be easily assembled, in spite of the deformations of the walls (18) of the cells (16) due to manufacturing tolerances and to the optional forming of the waffle core. Advantageously, several separative components (20) are supported by a same positioning unit (22), which then allows relative displacement between the separative components.

Disclosed herein is a curved honeycomb structure. The curved honeycomb structure is easily produced by placing respective flat plates composed of metallic or plastic material between moulds of a press machine or vacuum molding machine for forming a curved shape, forming honeycomb-shaped hexagonal cell pillars to protrude from a surface of each curved plate, followed by engaging the hexagonal cell pillars of the upper and lower plates with each other, and bonding them to each other. During forming the honeycomb structure, the hexagonal cells are not crushed or extended, and the strength of the honeycomb structure is substantially the same as that of the flat plate. In addition, the curved plate can have various shapes, and the productivity can be enhanced without increased material consumption.

Spatial location systems can be based on multi-resolution grids such as mixed aperture combinations of hexagonal cells. A particular finest resolution can be selected based on a suitable combination of intermediate grid apertures such as arbitrary combinations of aperture 3, aperture 4, and aperture 7 hexagons. Location identifiers can be uniquely assigned by generating child cells from a parent cell so that the generated child cells do not overlap child cells of other parent cells. One or more child blocks can be used at any resolution to avoid such overlap. For aperture three and aperture four hexagonal cells, blocks of four and three child cells, respectively, can be used to provide unique location identifiers.

The present product started in 2012 as an idea of the author to find a way to optimize and increase typing speed for smartphones during SMS or mail writing given that the existing methods are not optimized and they often cause difficulties, limitations or slow down text insertion. The technical problem to solve is "to develop an intelligent keyboard that is fast and intuitive, designed for devices using either a touchscreen keyboard (cell phones, smartphones and tablets as well as ticket emission machines, ATM machines, etc.) or a physical keyboard (many smartphones, old generation cell phones), which are used mostly with a single hand or even with a single finger in case of smaller devices ". The solution to this problem originates from blending together a few main ideas as stated below: 1) Creation of a new, well proportioned layout featuring hexagonal cells (FIG. 1) that is designed to diminish the distance traveled by the finger in order to reach all the keys in order to increase the typing speed; 2) Study of cryptoanalysis, i.e. the use frequency of letters in different languages (FIG. 2-5). Deciding the position of the letters in the above layout in an intelligent way visibly improves the efficiency, the intuitive use and speed of use as well as the use of intuitive and innate meccanisms of our brain such as mental associating and linking. 3) Completely changing the classic QWERTY layout (studied and developed in 1864 for two-handed use on very different devices) by moving the space key in the center of the new ad-hoc created layout (FIG. 1) and adding a bigger number of alphanumeric symbols thanks to the easily interchangeable supplementary layouts having the same structure (FIG. 6-7). The applicative field is on a world scale, the concerned technological ambits are many, ranging from telecommunications to any industrial appliance having a virtual keyboard, from teaching to information exchange.
