Abstract: An anti-reflective coating system configured to resist crazing resulting from applied compressive forces, and an optical article employing the anti-reflective coating system; and methods of forming the same. The methods include forming a first anti-reflective coating over a first surface of the optical article and applying a second anti-reflective coating over a second surface of the optical article, where the second anti-reflective coating has substantially the same reflectance than the first anti-reflective coating and a mechanical property distinct from the first anti-reflective coating.

Abstract: A method includes receiving time series source data that is associated with a source asset and that includes a set of classification labels. The method also includes receiving time series target data that is associated with a target asset and that lacks classification labels. The method further includes determining time series representations from the time series source data and the time series target data. The method also includes, based on the set of classification labels included in the time series source data and at least on raw time series data or the time series representations, generating a classifier operable to classify unlabeled data associated with the target asset. The raw time series data includes the time series source data and the time series target data.

Abstract: A gas and liquid separation system could be said to have a passage with an inlet connected to receive a mixed gas and liquid flow. An air separation tube extends into the passage at a location downstream of where the inlet is connected with an upstream tube end upstream in the passage relative to a downstream tube end. The upstream tube end provides an obstruction to the mixed gas and liquid flow, to cause separation of the gas from the mixed gas and liquid flow. A liquid tube is connected to the passage at a location downstream of the air separation tube.

Abstract: The present application discloses a method and apparatus for compensation of focal errors in laser beam measurement instruments that characterize beam parameters by analyzing images of Rayleigh scatter taken at multiple angles around the beam axis. If the laser beam is not precisely positioned, these images may not be in focus, and the instrument will not report accurate results. This method and apparatus finds the longitudinal axis of the beam by analyzing the beam location in at least two images. All images are subdivided into slices and distances from the beam axis to the focal plane for each slice are calculated and used to find an out-of-focus transfer function for each slice, which is used in combination with the modulation transfer function of the system to deconvolve the slice. Images formed by reassembling the deconvolved slices can then be analyzed to obtain the correct beam parameters.

Abstract: A refillable flosser dispenser including a housing and a cover. The housing can include a dispensing body, a door attached to the dispensing body, and a multi-state actuator structured to alternate between compressed and extended positions. The interior space created by the dispensing body and the door is structured and configured to house flossers in a stacked orientation. The cover can include an open bottom and can fit over and around the housing, the cover having an interior shape larger than an exterior shape of the housing. By pushing the cover down, the user activates the multi-state actuator, which causes a bottom portion of the housing to be exposed so that the user can remove a single flosser at a time. The top and bottom halves of the housing are mirror images of each other and allow the dispenser to dispense from either end, thereby making the dispenser ambidextrous.
