Abstract: A stylus and a control method are provided. The stylus includes: a device body and a touch part. The touch part is arranged at at least one end of the device body. The stylus further includes a first electrode arranged at one end of the touch part far away from the device body, a second electrode and a third electrode arranged on the touch part, and a control circuit arranged on the device body. The control circuit is electrically connected to each of the first electrode, the second electrode, and the third electrode. The second electrode and the third electrode may increase the size of the electrode and ensure efficiency of data transmission between the stylus and a touch device. In addition, the included angle information is detected by using any one of the second electrode or the third electrode.

Abstract: The present disclosure provides a camera control method and a mobile terminal. The method is applied to a mobile terminal. The mobile terminal includes an accommodating space for accommodating a retractable camera assembly. The retractable camera assembly includes a camera and a motor, the motor is connected to the camera via an elastic transmission structure for driving the camera to move. The method includes: identifying a current state of the camera when a triggering operation against the camera is detected, where the triggering operation includes a pressing operation or a stretching operation, and the state of the camera includes a retracted state, an extended state, a retracting process or an extending process; controlling movement of the camera according to the triggering operation and the current state of the camera.

Abstract: A tactile sensation providing method and device. The tactile sensation providing method includes: generating a first tactile sensation based on information of a contour attribute of a visual object; generating a second tactile sensation based on information of a texture attribute of the visual object; and generating a third tactile sensation based on information of a roughness attribute of the visual object.

Abstract: An unlocking method and a mobile terminal are provided. The unlocking method includes: in the case that a mobile terminal is locked, a touch chip determines whether a fingerprint verification operation is detected; in the case that the fingerprint verification operation is detected, the touch chip sends control signals to a central processor and a fingerprint driving chip; the fingerprint driving chip drives, in response to the control signal, a fingerprint sensor to collect fingerprint information, and determines whether the collected fingerprint information matches preset fingerprint information; and if so, the central processor unlocks the mobile terminal in response to a second control signal and a determination result from the fingerprint driving chip.

Abstract: Lateral flow assay devices, systems, and methods described herein measure concentration of a plurality of analytes of interest in a sample, and can determine the precise concentration of the plurality of analytes of interest, where one or more analytes of interest are present in the sample at high concentration and where one or more analytes of interest are present at low concentration. Precise concentration of each of the plurality of analytes can be determined when a single sample is applied to a single lateral flow assay in a single application, including when a first analyte of interest is present in the single sample at one-millionth the concentration of a second analyte of interest in the single sample.

Abstract: Sandwich-type lateral flow assay devices, kits, systems, and methods described herein include antibody-conjugated oversized particles that bind to analyte of interest in a sample and remain upstream of the capture zone when a fluid sample is applied to a lateral flow test device. Embodiments of the antibody-conjugated oversized particles allow for the precise determination of concentration of the analyte in the sample, including analyte present at high and very high concentrations. Lateral flow assays of the present disclosure can address drawbacks associated with the hook effect of sandwich-type lateral flow assays by eliminating the phase of the dose response curve where signal intensity is decreasing.
