| 技术特征B《直接公开》 | [0006] “modifying a first set of one or more modulation parameters for transmitting the identifier using VLC, where the first set of one or more modulation parameters may be modified based at least in part on the illumination factor;” <br> [0062] “In some examples, one or more modulation parameters may be adjusted (e.g., modified) so that a total light output of a light source is equal to a predetermined value (e.g., in lumens or amperes). The total light output, V, may be based at least in part on an illumination factor (e.g., a percentage of dimness).” | 对比文件明确公开了至少部分基于所述照度因数修改用于使用VLC传输识别符的第一组调制参数,并且明确教导了调整调制参数是为了使光源的总光输出等于预定值,而该总光输出是基于照度因数的。这直接公开了“至少部分基于所述照度因数修改…调制参数以维持所述总光输出”的技术特征,其作用与目标专利相同,即通过调整调制参数来在改变照明亮度(照度因数)时维持总的光输出水平。 |
