Abstract: Imaging systems and methods for calibrating imaging systems are provided. The imaging system has a body, a scene image capture system that captures images using a taking lens system that can be set to a plurality of different focus distances, and a rangefinder that is capable of determining a distance between the imaging system and at least one portion of a field of view of the taking lens system. The method comprises: automatically capturing a first calibration image of a first field of view through the taking lens system with the taking lens system set to a first focus distance setting; identifying a portion of the first calibration image having a predetermined degree of focus; using the rangefinder to determine a first calibration distance from the imaging device to the identified portion. A focus correlation is determined based upon the first calibration distance and the first focus distance setting.

Abstract: A heald control system has a heald rod which is reciprocated along its longitudinal axis and has a resiliently deflectable body portion formed from a magnetically attractable material and a retention latch formation. During reciprocation, the heald rod is moved along a path of travel between first and second limits in a first zone where the body portion normally travels in a undeflected position and in a second zone where the body portion travels in a deflected position. A fixed cam is engageable with a cam on said body portion during the reciprocation to cause the body portion to move from the non-deflected to the deflected position during travel from the first zone into the second zone. A fixed latch is located to one side of the first zone of the path of travel to engage the latch formation only when the body portion is in said deflected position. An electromagnet is located adjacent said path of travel of the body portion when it is in its deflected position, so that the electromagnet when energized is capable of holding the body portion in the deflected position as the latch formation moves from the second zone and into registry with the fixed latch to cause the latch formation to engage the fixed latch.

Abstract: The metering device for metering the weft yarn of a loom comprises a metering roller which is disposed between a supply unit and a draw off unit and which, in metering operation, is wrapped around by the weft yarn and determines the weft yarn draw off speed. In the event of a weft yarn break, a new waft start is injected past the metering roller into a catching nozzle and by way of a deflector into a yarn accumulator. A brake terminates the injection step. While a draw off element applies tension to the yarn, the yarn is wrapped automatically and in a number of turns around the metering roller by being moved into a catching zone of a catcher, which is rotatable around the metering roller axis, through the agency of a relative movement between the injected weft yarn and the catcher. During one revolution of the catcher around the roller axis, the weft yarn is deposited on the metering roller in the form of a wrapping. After a number of wraps of weft yarn around the metering roller, a severing element parts off the remainder of the yarn moving towards the accumulator and the resulting new yarn tip is moved by the metering roller into a start position for the weaving cycle.

Abstract: A dual sensor camera that uses two aligned sensors each having a separate lens of different focal length but the same f-number. The wider FOV image from one sensor is combined with the narrower FOV image from the other sensor to form a combined image. Up-sampling of the wide FOV image and down-sampling of the narrow FOV image is performed. The longer focal length lens may have certain aberrations introduced so that Extended Depth of Field (EDoF) processing can be used to give the narrow FOV image approximately the same depth of field as the wide FOV image so that a noticeable difference in depth of field is not see in the combined image.
