Abstract: Construction vehicles using a teach and repeat system can ascertain boundaries of a task area while working, without knowing a perimeter of the task area before starting the task. The system maps a first path of the vehicle by recording a position of a vehicle moving from a first start position to a first end position. A second path is predicted, based on a shape of the first path, the second path having a second start position and a second end position. A third path is mapped from a third start position to a third end position. Boundaries of the task area are ascertained based on the first path, the first start position, the second start position, the third start position, the third path, the first end position, the second end position, and the third end position.

Abstract: A multilayered, flexible, and generally flat pouch for transporting and dispensing fruit juice concentrate, including a first elongated, generally rectangular multilayered portion sealed to a second elongated, generally rectangular portion to yield a deformable, generally rectangular, fluid-tight sachet defining an internal volume and separating the internal volume from an external environment, wherein the sachet further defines a top end, and oppositely disposed bottom end, and first and second sides extending therebetween. Fruit juice concentrate is contained within the internal volume. A tear notch is formed through at least one side. The fruit juice concentrate has a water activity of less than 0.60.

Abstract: An electrical-discharge machining tool comprising a ground electrode, a moveable and activatable assistive electrode and a cutting electrode, a first conduit for supplying a dielectric and a second conduit for flushing dielectric material, wherein when used on a dielectric layer on a substrate the assistive electrode is activated and positioned substantially between the ground electrode and the cutting electrode.

Abstract: A repair system for in-situ repair of a machine. The repair system includes a laser unit configured to emit a laser beam, a galvanometer optically coupled to the laser unit and configured to adjust the laser beam received from the laser unit, a source of a flexible metallic mesh, a delivery unit configured to receive the flexible metallic mesh from the source of the flexible metallic mesh, and a controller communicably coupled to the laser unit, the galvanometer, and the delivery unit. The controller is configured to control the delivery unit to deposit the flexible metallic mesh on a surface of the machine. The controller is further configured to control the laser unit to emit the laser beam and to control the galvanometer to adjust the laser beam in order to weld the flexible metallic mesh to the surface of the machine, thereby forming a repair patch.

Abstract: A method for the removal of debris (75) from an aperture (60), the aperture comprising a first aperture diameter (64) and extending along a first axis (62) over a first distance (63), the method comprising the steps of aligning a beam of energy (80) with the first axis such that the beam of energy is coaxially aligned with the aperture, the beam of energy comprising both an energy sufficient to remove the debris, and a first beam diameter (82) which is less than the first aperture diameter; and, exposing the debris to the beam of energy in order to remove the debris from the aperture.

Abstract: An electro-discharge machining (EDM) device that includes a housing, an erosion electrode, a ground electrode, and a dielectric inlet. The housing is configured to be positioned on a surface of a workpiece and proximal to a fastener to be eroded. The planar erosion electrode is positioned at least partially within the housing, with the erosion electrode being movable relative to the housing in a first axis. The first axis is substantially normal to a longitudinal axis of the fastener. The ground electrode is conductively connected to the fastener. The dielectric inlet is configured to deliver a dielectric fluid to a region between the erosion electrode and the fastener.

Abstract: Described herein is a visual indication system implemented on a mobile machine. The visual indication system at least partially surrounds the mobile machine and includes a plurality of displayable regions. Objects surrounding the mobile machine are detected using an object detection sensor. A direction with respect to the mobile machine is detected for each of the objects. A current state of the mobile machine is determined. An object-directed indicator for each of the objects is generated based on the current state of the mobile machine. The object-directed indicator for each of the objects is displayed on the visual indication system at a particular displayable region based on the direction of the particular object.

Abstract: A dielectric gel for use in electro-discharge machining. Aspects of the dielectric gel include a liquid solvent phase entrapped in a three-dimensionally cross-linked fibre network.

Abstract: Various embodiments provide novel tools and techniques for photogrammetric machine measure-up, including without limitation solutions that can be used for excavation and similar applications. A system includes a machine, a user device may further comprise an image sensor, an accelerometer, a processor, and a computer readable medium in communication with the processor, the computer readable medium having encoded thereon a set of instructions executable by the processor to photogrammetrically measure-up the machine. Photogrammetric measure-up includes capturing, via the image sensor, two or more target images of each of the two or more targets, the two or more target images including a first target image and a second target image, and determining a measurement between two of the two or more reference features of the machine based on a first target image and second target image.
