Abstract: A keycap lifting mechanism increases the stability of supporting a keycap through structure designs of supports. For example, a pivot of two supports overlaps base holes of the supports along the pivot axis. For another example, each of supports has support arms extending non-parallel to the pivot axis. The free end of each support arm is connected to a base plate. For another example, among a plurality of pivotally-connecting structures between supports, at least one includes a fully-open pivot hole, achieved by two opposite hooks, and at least one includes a semi-open pivot hole, achieved by two opposite hooks and a blind hole. A long rectangular keyswitch structure includes a keycap and any of the above mechanisms. The distance from a sliding hole of one support to an adjacent keycap long side is greater than the distance from a holder hole of another support to another adjacent keycap long side.

Abstract: A keycap lifting mechanism increases the stability of supporting a keycap through structure designs of supports. For example, vertical projections of a sliding hole, a holder hole, and a base hole of supports overlap in a short side direction. For another example, vertical projections of a sliding hole, a holder hole, and a pivot hole of supports overlap in the short side direction. For another example, within the coverage range of a dome hole formed by supports in a long side direction, the supports do not have a structure connecting with other components. For another example, within the coverage range of two arms on opposite sides of the dome hole, there are more than 8 connection portions on the supports for connecting with a keycap and a base plate. For another example, the width of the arm is 0.8 to 2 times the length of the arm.

A continuous spectrum of a thermal radiation object is collected by a spectrometer; the spectrum of the thermal radiation object is denoised, windowed and standardized; the whole detection wavelength range is traversed within an appropriate narrow-band window; through comparison with windowed and standardized black-body radiation spectra at different temperatures in a corresponding spectral window, the temperature and emissivity distribution of the thermal radiation object is calculated with high accuracy without depending on emissivity model estimation, and high universality and noise resistance are achieved.

Abstract: Disclosed in the present invention is a visual monitoring method for cross-section temperature fields and radiation characteristics of boiler furnaces by combining radiation images and spectra. Image detectors can be directly inserted into observation holes of a boiler to acquire flame image data, so that when the detection system is applied to a power station boiler, extra holes are not required to be drilled, and therefore, there is no risk that the strength of a furnace wall of the boiler is reduced by drilling holes. According to cross-section temperature fields of a furnace measured by the detection system, the state of combustion in the furnace can be accurately judged, which can play an accurate and effective guiding role in boiler combustion control, and reduce the temperature deviation in each combustion area of the boiler so as to keep the boiler running smoothly, thereby improving the combustion efficiency of the boiler.

Abstract: A data providing apparatus obtains first privacy data and second privacy data, encrypts the first privacy data by using an encryption algorithm to obtain a ciphertext of the first privacy data, and sends the ciphertext of the first privacy data and the second privacy data to a data processing apparatus. The data processing apparatus inputs the ciphertext of the first privacy data and the second privacy data into a ciphertext computation function to obtain a ciphertext of a data processing result. In this way, the first privacy data is used in computation in a ciphertext form, thereby ensuring security. In addition, the second privacy data is used in computation in a plaintext form, thereby reducing ciphertext input for the ciphertext computation function.
