  • Publication number: 20240068135
    Abstract: Interlacing equipment may be used to form fabric and to create a gap in the fabric. The fabric may include one or more conductive strands. An insertion tool may be used to align an electrical component with the conductive strands during interlacing operations. A soldering tool may be used to remove insulation from the conductive strands to expose conductive segments on the conductive strands. The soldering tool may be used to solder the conductive segments to the electrical component. The solder connections may be located in grooves in the electrical component. An encapsulation tool may dispense encapsulation material in the grooves to encapsulate the solder connections. After the electrical component is electrically connected to the conductive strands, the insertion tool may position and release the electrical component in the gap. A component retention tool may temporarily be used to retain the electrical component in the gap as interlacing operations continue.

  • Patent number: 10913523
    Abstract: An adaptable modular power system (AMPS) is hierarchical in a number of ways. AMPS modules connect to a backplane, and one or multiple AMPS backplanes can form an AMPS domain. At the same time, the vehicle electronics is modular, with various payload boxes needing to communicate with each other. A common power and signaling cable is provided to interconnect payload boxes. A dedicated connector system is also provided so that AMPS modules may communicate, control, receive data, and supply and receive power.

  • Patent number: 8844416
    Abstract: A lattice cutting or slicing machine includes a multi-knife lattice cutting plate mounted in-line along an hydraulic flow path through which vegetable products such as potatoes are propelled in single file by a hydraulic fluid such as water. The lattice cutting plate is orbitally driven for engaging in succession each of the multiple knives thereon with the vegetable product to form lattice cut slices wherein successive generally corrugated cuts are angularly oriented typically perpendicular to each other, and further wherein the depths or troughs of the corrugated cuts on opposite sides of each slice intersect in the preferred form to define a pattern of corrugations interrupted by small openings.

  • Patent number: 8435583
    Abstract: An improved production process for preparing parfried and frozen French fry potato products with reduced crumb generation particularly upon finish preparation as by finish frying. Potato products such as French fry strips are cut, blanched and parfried, followed by a water treatment step as by applying a light spray or mist of water at ambient temperature and preferably at a rate selected to avoid any substantial overspray. The potato products are frozen for shipment and/or storage awaiting finish preparation. Upon finish preparation as by finish frying in hot oil, the potato products exhibit substantially reduced crumb generation. The improved process is particularly useful when parfrying and/or finish frying the potato products in a liquid or substantially non-hydrogenated oil, such as a zero grams Trans Fat (ZGTF) oil, with dramatically reduced crumb generation upon finish fry preparation while retaining a substantially optimized balance of sensory characteristics.

  • Publication number: 20120024125
    Abstract: A loop cutter knife fixture for cutting vegetable products such as raw potatoes into spiral or helical loops. The knife fixture includes a circular blade holder adapted to be rotatably driven within a vegetable product flow path. The blade holder includes a central core cutter in combination with a spiral base plate defining a radial slot between axially spaced upstream and downstream ends thereof. Small slits are formed in this base plate for seated reception of preferably multiple U-shaped strip blades, which are in turn overlaid and clamped in place beneath a generally pie-shaped slab blade having a sharpened knife edge exposed at the base plate radial slot and held in place by preferably multiple clamp screws. The strip blades and/or the slab blade are formed from an inexpensive material, such as sheet metal or the like, whereby blade changeover is quick and economical.
