Objective
To investigate whether the risk of interstitial cystitis increases among the patients with systemic lupus erythematosus.
Methods
This was a nationwide population‐based cohort study. Data were obtained from the National Health Insurance Research Database in Taiwan. Women aged >18 years newly diagnosed as systemic lupus erythematosus during 2001–2008 were identified as the control group...
Two methods to measure the luminance of backlight units with high contrast by a frame CCD camera are proposed. The measurement uncertainties are compared.
An inspection system for adjusting luminance of LED backlight units is disclosed to provide a uniform light source of LCD. By adjusting the LED current, target uniform backlight luminance values and distribution can be obtained.
Concept of using charge coupled device camera embedded with a calibrated image-processing algorithm as a two-dimensional luminance meter was successfully realized and verified with a small-scale backlight unit tester. This built apparatus takes only 3 seconds to get data of 10,000 points spreading uniformly in a 4-inches target, with target arbitrarily oriented. These merits make the tester more attractive...
