Abstract: An end effector for the packaging industry comprises has a frame, a bridge on top of the frame, a rack and pinion assembly, actuation rods, carrier assemblies, and vacuum ports. The rack and pinion assembly is configured to be operatively connected to a robot's rotatable shaft, and to the actuation rods. The actuation rods are fixedly connected to one or more of the carrier assemblies. As the robot's shaft rotates, the rack and pinion assembly is actuated, which actuates the actuation rods, which causes the carrier assemblies fixedly connected to the actuation rods to move longitudinally along the frame. Each carrier assembly includes a carrier block and at least one pick-up member. Each carrier block has at least one arm with a grabber to cooperate with an adjacent arm with grabbers of an adjacent carrier block(s) of the same subgroup.

Abstract: An optical imaging system includes a birefringent element, a light modulating element, and a polarizer element. The birefringent element is configured for decomposing un-polarized light into first linear polarized light and second linear polarized light under different refractive indexes to respectively form a first focal length and a second focal length in the optical imaging system. The light modulating element is configured for modulating a state of polarization of the first and second linear polarized light in response to control signals. The polarizer element is configured for filtering out one of the modulated first and second linear polarized light for creating a single image.

Abstract: A system and method for contactless handprint capture is disclosed that includes an image capture device to capture handprint images of a subject hand at each of a plurality of different focal distances, with the image capture device including an imaging camera and an electro-optics arrangement having a plurality of light modulating elements and polarization sensitive optical elements having differing optical path lengths based on polarization states. A control system is coupled to the image capture device to cause the device to capture the handprint images at each of the different focal distances, with each handprint image having a depth-of-focus that overlaps with a depth-of-focus of handprint images at adjacent focal distances such that redundant handprint image data is captured. The control system registers each handprint image with positional data and creates a composite handprint image from the handprint images captured at the different focal distances.

Abstract: An image capture device includes an electro-optics arrangement having an arrangement of polarizers, polarization sensitive optical elements, and polarization modulating elements. First and second polarization sensitive optical elements are provided having an edge displaced relative to a plane normal to an optical axis of the electro-optics arrangement. A control system coupled to the electro-optics arrangement controls the application of voltages to the polarization modulating elements to control the polarization rotation of the light input to the polarization sensitive optical elements, such that the optical path length of the polarization sensitive optical elements is changed to provide for capture of the object images at each of the different focal planes. The first and second polarization sensitive optical elements generate lateral image shifts between respective object images captured at the different focal planes responsive to the polarization rotation of the light input thereto.

Abstract: A method and system for monitoring creep in an object are provided. The creep monitoring system includes a creep sensor assembly that includes at least one image pattern pair disposed on a surface of the object. The creep monitoring method includes receiving information from the creep sensor assembly regarding an observed creep and an offset associated with the object, correcting the observed creep using the information regarding the offset and outputting the corrected information relative to the creep.

Abstract: Disclosed are method and apparatus for forming multiple images of an object comprising a plurality of depth segments. An optical system comprises an infinity optical subsystem and a multi-image optical subsystem. The infinity optical subsystem is configured to receive light from the object and form a first image focussed at infinity. A multi-image optical subsystem is configured to receive the first image and form multiple images via multiple focussing lenses. Each multiple image can correspond to a different depth segment. A portion of the light from the first image can also be filtered before entering a focussing lens. Multiple images under different filtering conditions, corresponding to different depth segments or to the same depth segment, can be formed.

Abstract: A probe system includes an imager and an inspection light source. The probe system is configured to operate in an inspection mode and a measurement mode. During inspection mode, the inspection light source is enabled. During measurement mode, the inspection light source is disabled, and a structured-light pattern is projected.

The probe system is configured to utilize pixel values from the at least one measurement mode image to determine at least one geometric dimension of the object. A probe system configured to detect relative movement between a probe and the object between captures of two or more of a plurality of images is also provided.
