An electronic imaging system having an image sensor array that includes photodetectors arranged in rows and a rolling shutter for initiating charge integration by row and reading out pixel signals by row after a lapse of a predetermined integration time is equipped with a lighting unit having an LED array including rows of LED elements for producing flashes in different directions, respectively, and a circuitry for exciting and extinguishing the LED rows, one at a time. The LED rows are allocated to a plurality of sections into which the image sensor array is divided, one row to each section. The circuitry initiates excitation of each LED row allocated to a given section of the array at the beginning of charge integration of a first row of the given section and extinguishes the LED row at termination of charge integration of a last row of the given section.

The invention provides a method for treating highly fluorine-contained wastewater, wherein four reaction tanks orderly overflowed are used, according to the weight ratio of calcium to fluorine of 3 to 1, the wastewater is fully mixed with calcium hydroxide solution with the concentration of 5 percent in the No. 1 reaction tank; in the No. 2 reaction tank, the overflowed water of the No. 1 reaction tank is fully mixed with calcium chloride solution of calcium hydroxide emulsion of which the concentration is 8 percent and the weight is 40 percent of the weight of the overflowed water of the No. 1 reaction tank; in the No. 3 reaction tank, the overflowed water of the No. 2 reaction tank is mixed with polyaluminum solution of which the concentration is 1 percent and the weight is 40 mg for each liter of the overflowed water of the No. 2 reaction tank; in the No. 4 reaction tank, the overflowed water of the No. 3 reaction tank is mixed with the polyacrylamide solution of which the concentration is 10 percent and the weight is 20 mg for each liter of the overflowed water of the No. 3 reaction tank; and the treated water from the No. 4 reaction tank is sent in a radial flow type sedimentation tank, and the supernatant of the radial flow type sedimentation tank is discharged into a clear water tank, and lower layer sludge is pumped in a sludge thickener for further sedimentation and separation. The fluoride concentration of the industrial wastewater is reduced to below 10 mg / L after being treated, thereby meeting the national pollution discharge standards.

The invention discloses an electricity-saving method and an electricity-saving method device of an AMOLED (Active Matrix / Organic Light Emitting Diode) display screen, and a terminal system. The method comprises the following steps of determining a display position and display resolution of a part of display area in the AMOLED display screen; according to the display position and the display resolution, adjusting scanning signal output and / or data signal output of the AMOLED display screen so as to adapt to the part of display area. The method and the device have the advantages that 1, operation is simple, the aim of adapting to the display position and the display resolution of the part of display area is fulfilled by adjusting the scanning signal output and / or data signal output of the AMOLED display screen, and the display forms are variable; 2, electricity is greatly saved, due to the fact that the AMOLED display screen is not provided with a backlight light source, and except a driving display part, the other parts of the whole screen are in a closed state, the electricity consumption of the AMOLED display screen is effectively reduced, and the battery cruising ability of the terminal system is also increased.

The invention discloses a method and system for adjusting a DRX parameter under LTE. The method comprises the steps: S1, building a carried QCI at a base station side according to UE, selecting a DRX initial parameter and transmitting the DRX initial parameter to the UE, starting a DRX function of the UE, and setting a counter T1 for counting the starting times of a spare timer; S2, starting to count the starting times T1 of the spare timer in a period at the base station side after T1 is cleared as zero at the starting point of each DRX period; S3, determining an adjustment scheme for a continuous timer according to the value of T1 after the DRX period; S4, determining an adjustment scheme of the DRX parameters according to the adjustment scheme for the continuous timer. According to the invention, the method can adjust the DRX parameters according to the data amount of the UE and the adjustment condition of the UE, better prevents the unreasonable DRX parameters caused by the changes of the adjustment condition of the UE, and achieves a purpose of DRX power saving to a greater extent when large time delay happens to the UE or the power saving effect is not good.

A temperature measurement device and a temperature measurement method are provided. The temperature measurement device (100) includes: a first temperature sensor (11) and a second temperature sensor (12) that are provided at different positions in a base portion (100) that is in contact with a measurement subject; and a computation processing unit (300) configured to calculate a temperature of the measurement subject by using temperatures detected by the first temperature sensor (11) and the second temperature sensor (12). The computation processing unit (300) calculates the temperature of the measurement object by use of a heat budget relative coefficient representing the relative coefficient of the heat budget in the first temperature sensor (11) and the second temperature sensor (12) when the base portion (100) is allowed to contact with the measurement object, and by use of the detected temperature of the first temperature sensor (11) and the second temperature sensor (12).
