The invention discloses a cycle power generation device, comprising a battery, a motor and a generator. The battery is a rechargeable battery and is connected with the motor through a power transmission line. The motor drives the generator to rotate, and the electricity returns to the motor through the power transmission line in series after producing electricity, thereby achieving the cycle power generation by driving the motor. The battery is provided for starting the motor at the initial stage, and the motor is driven by the electricity from the generator instead of the battery, after driving the generator to produce electricity by rotating the motor. The electricity produced by the generator is linearly transmitted to the motor, and the motor drives the generator to generate electricity, which is the cycle power generation.
摘要:
Methods, systems, and devices for wireless communication are described that support a low peak-to-average power ratio (PAPR) precoded reference signal design for multiple-input, multiple-output (MIMO) transmissions. A user equipment (UE) may identify multiple sets of symbols associated with different reference signal waveforms, where each reference signal waveform may be associated with a low PAPR. In some cases, different single-carrier reference signal waveforms may be mapped to subsets of frequency resources through frequency division multiplexing (FDM) for a transmission on a single antenna. However, the addition of single-carrier waveforms through FDM for a transmission via an antenna may result in an uplink transmission having a high PAPR (e.g., as compared to single-carrier waveforms). The UE may reduce the PAPR of the uplink transmission by multiplexing the reference signal waveforms in the time domain (e.g., using time division multiplexing (TDM)).

Techniques are provided for frequency spectrum sharing that allows secondary operators to access a frequency band of a primary operator without interfering with the primary operator's use of the band, while ensuring service continuity for devices of the secondary operators. For example, there is provided a method that may involve identifying an outage on a first channel of a plurality of channels of a spectrum, wherein each of the plurality of channels is allocated to one of a plurality of operators. The method may involve migrating all mobile stations in communication over the first channel of the plurality of channels to at least one other channel of the plurality of channels during the outage.

Systems, methods, and devices are provided for an electronic display with thermally compensated pixels. Such an electronic display may have an array of pixels, at least some of which may be thermally compensated pixels that exhibit reduced thermal color shift over an operational temperature range. These thermally compensated pixels may have compensation electrodes that induce an electric field in the thermally compensated pixel that cause a reduction in color shift.

The method includes acquiring quality parameters of an input electron beam, wherein the input electron beam is provided by the electron gun to the electromagnetic lens system, acquiring a current set of operation parameters of the electromagnetic lens system, calculating quality parameters of an output electron beam of the electromagnetic lens system, based on the quality parameters of the input electron beam and one or more operation parameters of the current set of operation parameters, and determining, based on the quality parameters of the output electron beam, whether calibration of the SEM is required.
摘要:
An electronic device may be provided with a display such as a liquid crystal display. The display may have a layer of liquid crystal material interposed between upper and lower polarizers. A first substrate such as a thin-film transistor layer may be interposed between the liquid crystal layer and the lower polarizer. A second substrate such as a color filter glass layer may be interposed between the upper polarizer and the liquid crystal layer. The color filter glass layer may have opposing upper and lower surfaces. The lower surface of the color filter glass layer may have an array of color filter elements. To prevent damage to display, an electrostatic shielding layer may be formed on the upper surface of the color filter glass layer under the upper polarizer. Reflections may be minimized by using index-matching dielectric layers in the display or thinning the shielding layer.
