Abstract: A method to determine a binocular alignment includes measuring a disassociated phoria of a patient at a first simulated distance by presenting fusible images including targets with a first parallax corresponding to the first simulated distance, using a headset stereo display at a screen distance; presenting non-fusible images by presenting the target for a first eye with the first parallax and presenting a disassociated targetless image for a second eye, and measuring the disassociated phoria in response to the presenting of non-fusible images, using an eye tracker of the headset; and determining a vergence of the patient at the first simulated distance by presenting fusible images for the first and second eyes with the first parallax, corrected with the measured disassociated phoria; measuring an associated phoria in response to the presenting of fusible images; and determining the vergence as a combination of the disassociated phoria and the associated phoria.

Abstract: A glass bottle production line comprising a bottle mold which has a plurality of mold cavities arranged in a predetermined order for forming bottles from glass parisons and for transferring the bottles to a conveyor in a predetermined sequence corresponding to the predetermined order of the mold cavities. The conveyor has a hot end portion and a cold end portion for receiving bottles from the bottle mold at an elevated temperature at the hot end portion and conveying the bottles to the cold end portion. A hot bottle inspector located at a fixed inspection station along the conveyor at the hot end portion non-touchingly inspects the bottles as the bottles are conveyed past the inspection station by the conveyor. A mold transfer signal and bottle detection signal are processed to determine the mold cavity used to produce the bottle detected at the inspector's station.
