Abstract:
A poly sheet continuously moving in a machine direction is heated to a temperature just below its glass thermal temperature to make the poly malleable. A circuit (e.g., RFID chip, EAS chip, transponder, IC) is placed on the poly sheet and embedded into the poly sheet, preferably with a heat resistant soft (e.g., rubber) roller that presses the circuit into the poly without breaking the circuit. A conductive strip or wire may be applied on or into the poly sheet to align with connection points (e.g., conductive bumps) of the circuit for conductive communication with the circuit. The conductive strip or wire is preferably cut to form gaps that are nonconductive between the cut sections of wire to avoid shorting of the circuit and/or allow the conductive strip or wire to function as an antenna for the circuit, and thus to form a chip strap or tag. The poly sheet thus provides a protective womb or shield for the circuit and wire.
Abstract:
A rotary chip attach process and manufacturing approach takes chips (e.g., integrated circuits (ICs)) from a wafer in a rotary process. A chip wafer with a positioning unit is placed over the top of a sprocketed wheel that picks the ICs directly from the wafer and moves them in a semi-continuous in-step motion to a web that will accept the ICs. The sprocketed wheel includes chips that are preferably the same type as used in a typical pick-and-place robotic system, with vacuum heads adapted to pierce the wafer flat membrane (if needed), grab and IC and place and IC as desired. This positioning system keeps the IC's placement in an accurate position on the web, which can be made to move continuously with a plurality of sprocketed wheel placement units in place.
Abstract:
A method of making UHF antennas for security tag and antennas thereby. A web of electrically conductive material having a thickness in the range of approximately 5 to approximately 50 microns is releasably secured to a carrier web using a releasably securable adhesive substantially coextensive with the conductive web. A series of antennas of a desired shape are die-cut into the conductive web, but not into the carrier web. The portion of the conductive web not making up the antennas is in the form of scrap and is removed, thereby leaving the series of antennas releasably secured to the carrier sheet. The antennas are arranged to be removed from the carrier sheet, whereupon the releasably securable adhesive is transferred to them, so that they may be subsequently secured to other components to form a security tag.
Abstract:
A boat has a hull and a deck supported by the hull. The deck has a forward passenger area and a rearward passenger area. A seat is disposed in the rearward passenger area. A passageway allows for communication between the forward passenger area and the rearward passenger area. A door is disposed on the deck for selectively closing the passageway between the forward passenger area and the rearward passenger area. The door has a top, a front, a back, and two sides. A windshield is disposed generally transverse to a longitudinal axis of the boat. The windshield is movable between a first position where the windshield extends a first distance vertically above the top of the door and a second position where the windshield extends a second distance vertically above the top of the door. The second distance is less than the first distance.
Abstract:
A boat has a hull and a deck supported by the hull. The deck has a rearward passenger area. A seat is disposed in the rearward passenger area. A first console is disposed on the deck at a front of the rearward passenger area and forwardly of the seat. The first console has a top. A first windshield is disposed generally transverse to a longitudinal axis of the boat. The first windshield is movable between a first position where the first windshield extends a first distance vertically above the top of the first console and a second position where at least a portion of the first windshield extends a second distance vertically below the top of the first console. When the first windshield is in the second position the at least one portion of the first windshield is in a substantially vertical position.
Abstract:
A combination EAS and UHF security tag that adds the ability to add item level UHF functionality to a retail tag and maintain the integrity of the EAS systems installed in the business and whereby the EAS and UHF security elements are substantially formed from a common conductive layer. This combination tag also includes the ability to change a tag from a “far-field read” tag to a “near-field read” tag.
Abstract:
A method of fabricating a tag includes the steps of applying a first patterned adhesive to the surface of the substrate and applying a first electrically conductive foil to the first patterned adhesive. A portion of the first electrically conductive foil not adhered to the first patterned adhesive is removed and a second patterned adhesive is applied to a portion of a surface area of the tag. A preformed second electrically conductive foil is applied to the second patterned adhesive to adhere the second electrically conductive foil to the surface of the substrate and portions of the first and second electrically conductive foils are electrically coupled to each other to form a tag circuit. A second patterned adhesive can be disposed between the first and second electrically conductive foils.
Abstract:
A wire embedded bridge made by the apparatus and method disclosed by example herein may be commonly used for the formation of an RFID circuit or chip strap. The process uses flexible polyester and/or other films as a base component of the bridge. A wire is heated and embedded into the poly sheet at precise locations in a continuous process, for example, with the poly continuously moving in a machine direction. The locations of the wire make chip placement onto the wire track reliable and inexpensive, preferably using heat and pressure to bond the chips with the embedded wire and form a protected RFID circuit.
