Abstract: A head-mounted device may have a head-mounted support structure. Gaze tracking systems may be supported by the support structure so that the gaze of a user may be monitored. Lenses may be supported by the support structure. Display systems may provide computer-generated images to the user while the user is viewing real-world objects through the lenses. The gaze tracking systems may include image-sensor-based systems such as glint-based systems. A glint-based gaze tracking system may include light-emitting devices that emit light beams that create eye glints on the surface of a user's eyes and may include an image sensor that measures the eye glints to gather information on the user's gaze. A low-power gaze tracking system may be included in the head-mounted device. The low-power gaze tracking system may use light detectors to measure the magnitudes of respective light reflections of the light beams.

Abstract: A head-mounted device may have displays that provide images. Waveguides may be used in conveying the images to eye boxes. The waveguides may overlap lenses in a glasses frame or other head-mounted support structure. The waveguides and lenses may be transparent. This allows real-world objects to be viewed from the eye boxes. Infrared-light reflectors may overlap the lenses. Gaze tracking system light sources may supply infrared light that reflects from the infrared-light reflectors to the eye boxes to illuminate a user's eyes. Gaze tracking system cameras capture gaze tracking images of the eyes from the eye boxes to track the user's gaze. Fiducials associated with the infrared-light reflectors may be monitored using the gaze tracking system cameras. This allows components such as the gaze tracking system cameras to be calibrated.

Abstract: A system for enhanced conveying of flexible packages includes a packaging system, an inflation system, and a conveying system. The packaging system is configured to place an object in a flexible package. The inflation system is configured to insert a gas into the flexible package. The packaging system is further configured to seal an edge of the flexible package in an inflated state with the object and the inserted gas inside the flexible package. The conveying system is configured to convey the flexible package while the flexible package is substantially in the inflated state. The flexible package is configured to permit gas to escape the flexible package at a controlled flow rate such that the flexible package remains substantially in the inflated state while being conveyed by the conveying system and the flexible package transitions to being substantially in a deflated state after being conveyed by the conveying system.

Abstract: A system for packaging includes a continuous flow wrap machine, a product reader, and a labeling unit. The product reader is configured to sense each product of the series of products transported on the infeed conveyor of the continuous flow wrap machine and to provide detected information for facilitating access to unique product information associated with each sensed product of the series of products. The labeling unit is adapted to apply visual representation of the unique product information to the tube formed in the continuous flow wrap machine while the tube is moving or to the resulting packaged product while the packaged product is moving.

Abstract: A form-fill-seal system includes a tube feeding system, an end seal carriage (420), and a computing device. The tube feeding system feeds a tube (410) of flexible material at a first velocity (v1). The computing device controls the end seal carriage (420) to cause an increase in a velocity of the end seal carriage to substantially the first velocity (v1), a start of a dwell time of the end seal mechanism (424, 422) on the tube (410) of flexible material while the velocity of the end seal carriage is at substantially the first velocity (v1), and an increase in the velocity of the end seal carriage to a second velocity (v2) during the dwell time. The end seal mechanism cuts a package (440) from the tube during the dwell time. The increase in the velocity of the end seal carriage to the second velocity (v2) results in an increased distance of the package from the tube.

Abstract: A cushion package can be formed around an object. The object can be removed from and reinserted into the cushion package. The cushion package includes a cushion material (104) having a longitudinal length and two longitudinal edges (110). The two longitudinal edges (110) of the cushion material are folded into an overlapping position to form a tube of the cushion material. The cushion package includes first and second transverse seals (148,150) in the tube of the cushion material. The first and second transverse seals (148,150) respectively form first and second ends of the cushion package. Each of the first transverse seal and the second transverse seal (148,150) seals the cushion material with the two longitudinal edges (110) in the overlapping position. The two longitudinal edges (110) of the cushion material are uncoupled between the first transverse seal and the second transverse seal (148,150).

Abstract: A system of facilitating printing of shipping labels includes a computing device and a label printer. The computing device receive shipment database data from a remote computing device, store the shipment database data in a shipment database, receive scan data associated with an object from a scanning device, determine whether shipment data for the object is in the shipping database, determine shipping information for the object based on whether shipment data for the object is in the shipping database, and send shipping information to the label printer. The shipping information for the object is based on whether shipment data for the object is in the shipping database. The label printer prints a shipping label for the object based on the shipping information.

Abstract: A packaging system includes a conveyance system, a package forming system, and a tracking system. The conveyance system is configured to receive objects and to convey the objects through the packaging system. Spacing between the objects is non-uniform as the objects are received by the conveyance system. The package forming system is configured to feed a packaging material to form a tube of the packaging material and to seal the tube of the packaging material around the objects to form packages of the packaging material around the objects.

Abstract: A sealing machine having a movable carriage assembly which utilizes a counterbalance and two servo motors is disclosed. The counterbalance allows high throughput operation without excessive mechanical vibration. The use of two servo motors allows independent control of the horizontal movement of the movable carriage assembly and the vertical movement of the jaws. The use of two servo motors also allows adaptation to articles or packages of various dimensions. In some embodiments, an optical sensor is used to detect the position of the package to be sealed, and the movement of the movable carriage assembly and the jaw is altered based on the detected position.

Abstract: Control system and apparatus for controlling current input to an electrical resistance element such as a seal wire. The system and apparatus of the present invention is a closed loop feedback modification to conventional systems, and takes advantage of the inherent expansion of the seal wire as it is heated. The feedback mechanism monitors both the actual current passing through the wire, and the length of the sealing wire, and adjusts the current applied to the wire, responsive to those monitored inputs. The usage of the sealing machine is also monitored and the application and amount of current flowing to the wire is varied based on this usage.
