Abstract: Provided is a control method for de-icing blades of a wind power generator, including: Step S101: performing real-time monitoring of temperature of a surface of a blade of the wind power generator, and constructing a first positional temperature sequence at a time interval of v; and Step S102: calculating actual temperature at each position on the surface of the blade of the wind power generator according to the positional temperature sequence, and generating a second positional temperature sequence. In the present disclosure, it can be avoided that a discrepancy between the temperature acquired and the actual temperature of the surface of the wind power generator; and weight differences that may exist among three blades are taken into account, and synchronous de-icing operations are performed after eliminating the weight differences, so that ice treatment can be achieved without shutdown, and the stable operation of the wind power generator can be ensured.

Abstract: Disclosed are a narrow pulse width laser, a method for emitting narrow pulse width laser, a device, and a storage medium.

The pulse signal controller is configured to obtain a first pulse signal and a second pulse signal, the first pulse signal is identical to the second pulse signal, the first pulse signal is controlled to delay for obtaining a delay signal, there is a target phase difference between the delay signal and the second pulse signal, the delay signal is superimposed on the second pulse signal to obtain a target pulse signal.

Abstract: A display driver circuitry with permutation and superposition gray-level control comprises a gray-level controller. The controller may comprise a permutation and superposition adder configured to divide N-bit gray-level data G into M most significant bits, serving as a superposition reference GH, and (N?M) least significant bits, serving as a superposition increment GL, and to superpose superposition values Xi onto GH to derive pieces of scan data Gi for S scan operations; an overflow bit setting unit configured to set an overflow bit F; and an output unit configured to output the scan data Gi. A display driven this way has an improved refreshing frequency with the same gray-level reproduction ability as PWM-based schemes. Further, the duration of each scan operation, or scan period, is constant, resulting in convenience in software implementations. Furthermore, the pulse width representative of the gray-level value is determined by superposition of the scan operations.

Abstract: Systems and methods provide laser pulse equalization at different pulse repetition frequencies (PRFs). After initially pumping a lasing medium from a first pumping level to a peak pumping level, a controller may cause a pump source to continue pumping the lasing medium according to a pulse equalization pumping curve. The equalization pumping curve may be determined based on testing laser pulse parameters at different PRFs to achieve an optimal equalization result of the pulse parameters. The optimization metric used to evaluate various equalization pumping curves may include a consistency of the pulse energy level, peak power level, and/or pulse width of the laser under different PRFs. The equalization pumping curve may be a descending curve from the peak pumping level to the first pumping level. The equalization pumping curve may be a linearly declining curve, a substantially exponentially declining curve, a parametrically declining curve, or any other curve type.

Abstract: A programmable tailored laser pulse generator including a pulsed seed laser source, a laser amplifier, and an optical power amplifier produces high power tailored laser pulses shaped in response to a programmable analog tailored pulse signal applied to a seed laser (first embodiment) or an external modulator of continuous-wave seed laser output (second embodiment). The programmable analog tailored pulse signal is generated by combining multiple individually programmable analog pulses generated by a multi-channel signal generator. A bias applied to the pulsed seed laser source generates pre-lasing prior to producing a tailored laser pulse so that the seed laser source spectral line and line width stabilize within a narrow gain line width of a solid-state laser amplifier, thereby to impart pulse peak stability of the laser output.
