Patent MX-9708004-A (MX)
Title: Noise canceling system.
Inventor: DANIELS MARK A
IPC: F24F13/02
Filed: 1997-10-17
Abstract: Two microphones spaced along a duct of an air condictioning system provide inputs to circuitry whereby the noise being generated of distinguished from relfected noise. The circuitry imposes a time delay corresponding to the time requiered for generated noise to pass from the upstream microphone to a canceling speaker. The canceling speaker is driven by the circuitry, subject to the time delay, such that noise at the speaker is canceled by the appropriately driven speaker. In a preferred embodiment movement of the speaker in sensed whereby the actual sound being produced can be compared with the sound required by the canceling speaker driving signal.

Patent NL-2009846-A (NL)
Title: Radiation source and method for lithographic apparatus and device manufacture.
Inventor: SINGH HARMEET
IPC: G03F7/20
Filed: 2012-11-20
Abstract: A method of treating or operating a radiation source apparatus (SO), for instance for generating EUV radiation for device lithography, is disclosed. The method is for use with radiation source apparatus having a chamber (220) arranged to hold a plasma (210) for radiation generation, with the plasma excited from a metal fuel in use by a first plasma generator (LA). The method comprises flowing a gas (via 41) comprising hydrogen and boron hydride through the chamber with the gas in an excited state comprising free radicals of hydrogen. The presence of the boron hydride with the hydrogen radicals in the gas is effective cleaning or reducing build-up of metal fuel deposits on surfaces of the chamber or associated optics, particularly on reflective surfaces of the radiation collector mirror (CO). The method is particularly suitable for use with tin fuel. The hydrogen free radicals may be generated by the plasma (210) for radiation generation itself, or may involve exciting the gas using a second, separate free radical generator (41). The method may be used to reduce deposition whilst the radiation source apparatus is in use for generation of radiation or may be applied as a treatment for cleaning whilst radiation generation is interrupted.

Title: Metrology system, lithographic apparatus, and calibration method
Inventor: Nikhil Mehta
IPC: G03F7/20
Filed: 2020-01-28
Abstract: A lithographic apparatus includes an illumination system to produce a beam of radiation, a support to support a patterning device to impart a pattern on the beam, a projection system to project the patterned beam onto a substrate, and a metrology system that includes a radiation source to generate radiation, an optical element to direct the radiation toward a target, a detector to receive a first and second radiation scattered by the target and produce a first and second measurement respectively based on the received first and second radiation, and a controller. The controller determines a correction for the first measurement, an error between the correction for the first measurement and the first measurement, and a correction for the second measurement based on the correction for the first measurement, the second measurement, and the error. The lithographic apparatus uses the correction to adjust a position of a substrate.

Abstract: In a colour display device colour elements (17, 18, 19, 21, 22, 23) are built up with the aid of picture cells (2) from juxtaposed rows of picture cells which are driven by line electrodes (3). The resolving power in the horizontal sense is increased by building up the colour elements from picture cells of different rows of picture cells. The period t1 which is required for driving a colour element is split up into sub-periods 1/2 t1 during which period samples of the signal to be displayed (length to) are presented to the column electrodes (4). Since notably for LCD-TV there applies that t1 > to, these samples can be presented during a period which is longer than 1/2 to.
