  • Patent number: 10268270
    Abstract: Various systems, devices, and methods for shape deformation of a haptic deformation display device are provided. For example, the haptic deformation display device may receive an input signal when the shape of the haptic deformation display device is in a first shape configuration. In response to the input signal, the haptic deformation display device may activate an actuator of the haptic deformation display device. The actuator may move a deformation component of the haptic deformation display device. The deformation component may at least partially defining a shape of the haptic deformation display device, thereby causing the shape of the haptic deformation display device to deform into a second shape configuration different from the first shape configuration. The second shape configuration may be substantially maintained.

  • Patent number: 10253249
    Abstract: Methods for treating subterranean wells in which the producing formation is a carbonate comprise preparing a treatment fluid comprising either: (a) an aqueous solution of a multivalent-cation reacting polymer; (b) a solution comprising a fatty acid and an ethanolamine; (c) an aqueous acidic solution of one or more compounds whose calcium salts are insoluble; or (d) an aqueous solution comprising urea or alkane derivatives thereof or both and polyvinylpyrrolidone (PVP). The treatment fluid is placed in the well such that the solution contacts the carbonate formation at a pressure lower than the fracturing pressure. The treatment fluid is allowed to react with the carbonate formation, thereby depositing a film onto the formation surface or part of the formation surface. Then an acid solution is placed in the well such that the acid contacts the carbonate formation at a pressure lower than the fracturing pressure.
