Abstract: An electronic device such as a voice-controlled speaker may have an array of strain gauges and light-emitting diodes. The light-emitting diodes may be configured to display dynamically adjustable button icons overlapping the strain gauges. Force measurements from the strain gauges may be used to adjust speaker output and other device operations.

Abstract: A two-component microwave ferrite material, a preparation method therefor and an application thereof. The two-component microwave ferrite material comprises a first microwave ferrite material and a second microwave ferrite material. The preparation method comprises the following steps: (1) mixing a first microwave ferrite material and a second microwave ferrite material according to a formula amount, and then performing wet ball milling to obtain a ball abrasive; (2) drying the ball abrasive, sieving, and granulating; and (3) sequentially forming and sintering the granulated particles obtained in step (2) to obtain a two-component microwave ferrite material.

Abstract: The present disclosure is directed to systems and methods for providing improved tools (e.g., user interfaces) that can be used for managing access permissions to cloud or other network resources. In general, the systems and methods include providing a user interface that can function in at least two modes which together can provide an improved user experience for intuitively and effectively developing code. As an example, the two interface modes can include a builder mode in which the user interface includes one or more interactive elements that enable a user to modularly build a set of computer-readable code that controls access permissions to one or more computing resources and an editor mode in which the user interface allows the user to directly edit the set of computer-readable code.

Abstract: A method of preparing an organotin containing hyperbranched polysiloxane structure includes the following steps: (1) by weight, 0.5-1.5 portions of hyperbranched polysiloxane with reactive functional groups is dissolved in 50-100 portions of an alcohol solvent, to obtain a solution A; (2) by weight, 0.5-0.9 portions of a tin-based initiator and 50-100 portions of the alcohol solvent are mixed to obtain a solution B, wherein said tin-based initiator is selected from dihydroxy butyl tin chloride, butyl tin trichloride, and dibutyl tin dichloride; and (3) dropping the solution B into the solution A at the temperature of 0° C.-60° C., reacting for 3-6 h, filtering and drying to obtain the organotin containing hyperbranched polysiloxane structure.
