Abstract: The present application discloses a display device and method of an OSD menu.

Abstract: The disclosure relates to the technical field of trolleys, and in particular to a trolley frame, including four wheel carriers provided with roller wheels at lower ends and connected by a bottom folding stand. A side folding stand includes a support bar and at least two first X-shaped linkage assemblies. The support bar is arranged between the two first X-shaped linkage assemblies, and a lower end of the support bar is hinged to the bottom folding stand. A cloth bag can be well supported according to this solution, so as to reduce a risk of the cloth bag being damaged or torn in case of load bearing.

Abstract: A system for purifying helium gas, a method, and an application. The system includes a first gas-liquid separation device, a primary helium extraction tower, a second gas-liquid separation device, a secondary helium extraction tower, and a nitrogen removal tower, which are in sequential communication. The first gas-liquid separation device performs first treatment to convert helium-containing natural gas into a first gas and first liquid phases; the primary helium extraction tower performs first distillation on the first gas and first liquid phases to obtain a second gas and second liquid phases; the second gas-liquid separation device performs second treatment to convert the second gas phase to a third gas and third liquid phase; the secondary helium extraction tower performs second distillation on the third gas and third liquid phases to obtain crude helium and a fourth liquid phase form which nitrogen is removed by the nitrogen removal tower.

Abstract: An image processing method is disclosed. The image processing method includes setting n reference pixels around a pixel of interest, where n is an integer, sequentially comparing a pixel value of the pixel of interest with a pixel value of each reference pixel, counting a number of the reference pixels whose pixel values are less than or equal to the pixel value of the pixel of interest, incrementing a histogram value of each reference pixel by 1 to compare with a preset inclination limit value, counting a number of the reference pixels satisfying both a condition that the reference pixel value is less than or equal to the pixel value of the pixel of interest and a condition that the histogram value is less than or equal to the inclination limit value so as to obtain a true-in-both count value, and proportionally distributing the true-in-both count value for output.
