  • Patent number: 11816806
    Abstract: The proposed approach is a system and method that allows a user to calculate a 3D model for each of his or her feet using a simple reference object and a mobile computing device with one or more cameras and/or one or more sensors. The mobile computing device moves around the user's feet to scan and/or capture data of his or her feet via the camera and/or the sensors. The captured sensor data is then processed by the mobile computing device to create two sets of 3D (data) point sets (also referred to as “point clouds”). These point clouds are then matched to a 3D model of an average foot to establish a correspondence between the point clouds and the 3D model. Once the correspondence is established, the mobile computing device is configured to fit one or more morphable models to the user's feet.

  • Patent number: 9074613
    Abstract: The invention relates to a method and device for controlling the mass flow rate of a sonic gas stream in a pipe. To carry out the above operation, an electric discharge is applied inside the pipe so as to create a plasma in the pipe. The electric discharge allows for an increase in the temperature of the gas stream and thus a variation in the mass flow rate or the pressure of the gas stream. By periodically emitting the electric discharge, a pulsed or adjustable gas jet is obtained at the outlet of the device. The gas jet can then be used to control a main stream.

  • Patent number: 8846944
    Abstract: The present invention provides a method for regeneration of chiral 2,2?-cyclopropylidene-bis(oxazolines), such as (3&R,3?aR,8aS,8?aS)-2,2?-cyclopropylidenebis-[3a,8a]-dihydro-8H-indeno-[1,2-d]-oxazole and (45,4?5,5R,5?R)-2,2?-cyclopropylidenebis-4,5-diphenyldihydro-4,5-oxazole, used as a part of complex catalysts for e.g. stereoselective addition reactions, from the reaction mixtures, by selective sorption of 2,2?-cyclopropylidene-bis(oxazolines) on a sorbent, such as silica gel, isolation of the sorbent from reaction mixture, desorption of 2,2?-cyclopropylidene-bis(oxazolines) from the sorbent with suitable organic solvent and final recovery of 2,2?-cyclopropylidene-bis(oxazolines) from the organic solvent used for desorption process. Catalytic quality of recovered compounds does not differ from those in freshly prepared catalysts.
