Distinct context sets may be used for encoding the significant-coefficient flags in different regions of the transform unit. In a fixed case, the regions are defined by coefficient group borders. In one example, the upper-left coefficient group is a first region and the other coefficient groups are a second region. In a dynamic case, the regions are defined by coefficient group borders, but the encoder and decoder dynamically determine in which region each coefficient group belongs. Coefficient groups may be assigned to one region or another based on, for example, whether their respective significant-coefficient-group flags were inferred or not. |

A dynamic vibration absorber needs to be designed so that the natural frequency of the dynamic vibration absorber alone becomes equal to the natural frequency of a stator.

Thin optoelectronic modules with apertures and their manufacture
The wafer-level manufacturing method makes possible to manufacture ultrathin optical devices such as opto-electronic modules. A clear encapsulation is applied to an initial wafer including active optical components and a wafer-size substrate. Thereon, a photostructurable opaque coating is produced which includes apertures. Then, trenches are produced which extend through the clear encapsulation and establish side walls of intermediate products. Then, an opaque encapsulation is applied to the intermediate products, thus filling the trenches. Cutting through the opaque encapsulation material present in the trenches, singulated optical modules are produced, wherein side walls of the intermediate products are covered by the opaque encapsulation material. The wafer-size substrate can be attached to a rigid carrier wafer during most process steps. |
