  • Publication number: 20240299314
    Abstract: A method of synthesizing and a method of curing cancers using a nano device are disclosed, the nano device comprising: a framework comprising a structure formed by Si—O—Si covalent bonds and a plurality of mesopores configured to store drug cargos therein by disulfide covalent bonds; and an independent and separate chitosan layer, deposited directly on the framework. The chitosan layer is designed to coat and protect said framework layer from leaking the drug cargos in a first condition and to degrade so as to expose the drug cargos in a second condition. The framework releases the drug cargos by allowing a predetermined concentration of glutathione to break the disulfide (S—S) covalent bonds.

  • Patent number: 11216093
    Abstract: Methods, systems, and apparatus that detect computing device inputs by a pointing body are disclosed. One method includes detecting user inputs based on a received set of physical touches of a pointing body pressing an operation surface of a computing device indicating a pressed state of the operation surface detected by a pressure sensor, detecting a make event comprising a first physical touch including a first pressure value that is greater than or equal to a make threshold pressure value based on the detected user inputs, and utilizing a first threshold as the make threshold for use in detecting a first round of the make event and a second threshold, which is less than the first threshold, as the make threshold for use in detecting subsequent rounds of the make event within a first predetermined multi-click detection period of time. Systems and apparatus for performing the method are also disclosed.

  • Patent number: 10598208
    Abstract: An indentation tool includes an installation axis, a radially oriented indentation axis, and a defined reserved space for an indentation site of a cylindrically-shaped structure, as well as a base for installing onto the structure, and an elongate punch for indenting it at its indentation site. The reserved space is spaced apart from the installation axis, and has the indentation axis passing through it. The base extends along the installation axis, and is configured for coaxial installation onto the structure, whereby its indentation site occupies the reserved space. The punch is spaced apart from the installation axis, and is supported by the base for movement along the indentation axis between a home position, in which the punch vacates the reserved space, and an indentation position, in which the punch, leading with an indentation tip, reaches into the reserved space to indent the structure at its indentation site.
