  • Patent number: 11948547
    Abstract: An active noise control system selects one reference sensor providing a reference signal with the largest coherence to a noise signal, among a plurality of available reference sensors, as a first entry of a reference sensor set. After selecting the first entry, the active noise control system repeats a process in which a sensor capable of providing the largest information quantity to a current reference sensor set among remaining sensors is selected as a new entry of a reference sensor set, until a desired number of sensors is reached or a desired control level is reached. When the reference sensor set is determined, the active noise control system utilizes the entries of the reference sensor set to generates a noise control signal suitable for canceling the noise signal.

  • Publication number: 20240085791
    Abstract: The colored photosensitive resin composition of the present invention maintains excellent resolution, visibility, and the like while it has excellent reflectance RSCI measured by the SCI (specular component included) method, reflectance RSCE measured by the SCE (specular component excluded) method, and the ratio between them (RSCE/RSCI), and has a uniform film thickness in an appropriate range. Thus, it can be formed into a multilayer cured film that simultaneously satisfies such physical properties as a high reflectance and a high light-shielding property. In addition, when a cured film is formed from the composition, it is possible to form a pattern on a multilayer film in a single development process. Thus, it can be advantageously used for a quantum dot display device.
