  • Patent number: 6480101
    Abstract: A fast data transfer collection system using message authentication and contactless RF proximity card technology in non-contact storage and retrieval applications. The system is generally comprised of Host computers (application computer systems), Target radio frequency (RF) terminals, and a plurality of portable Tags (“smart” or “proximity” cards). A Host provides specific application functionality to a Tag holder, with a high degree of protection from fraudulent use. A Target provides control of the RF antenna and resolves collisions between multiple Tags in the RF field. A Tag provides reliable, high speed, and well authenticated secure exchanges of data/information with the Host resulting from the use of a custom ASIC design incorporating unique analog and digital circuits, nonvolatile memory, and state logic. Each Tag engages in a transaction with the Target in which a sequence of message exchanges allow data to be read(written) from(to) the Tag.

  • Patent number: 6471818
    Abstract: A process for applying a portion of a closed zipper inside a container of flexible material, in which a segment or portion of a closed zipper-strip is first applied by a fixing device upon the inner sides of a film of flexible material, prior to cutting of the zipper strip portion from the remainder of the zipper strip. The zipper portion is applied in such a position that it will not interfere with the subsequent sealing along transverse seal lines defining the opposite sides of the container.

  • Patent number: 6468616
    Abstract: A joint apparatus for joining two objects together with end faces in face-to-face engagement includes first and second flat elongate plates for attachment to faces of the respective objects adjacent the end face. Each plate has a first side edge for facing the first side edge of the other plate when secured to the respective object, and the first side edges each have a series of alternating tongues and recesses positioned for alignment with the recesses and tongues of the other plate, respectively. The plates are positioned on the respective objects such that the tongues project out from the end face of the object and engage in the recesses of the other plate when the end faces are abutted, in a zipper-like fashion. The plates may be temporarily clamped together while the tongues are secured to the face of the opposing object, thereby forming the joint.

  • Patent number: 6464405
    Abstract: An underwater connector has a plug and a receptacle unit each having an internal chamber in which a respective contact module is located. Each module has an end face having contacts for engagement with corresponding contacts on the other module when the units are releasably mated together. Each chamber has a resilient forward end with an opening communicating with the respective chamber, and an actuator in each unit compresses the forward end to seal the opening when the units are unmated. As the units are mated, the actuator in one unit is urged rearwardly and the forward end of the chamber in the other unit is urged rearwardly, such that each end opens to permit the module of one unit to pass into the chamber of the other unit, and into engagement with the other module so that all contacts are engaged for communication between the units.

  • Patent number: 6460786
    Abstract: Indicia are formed on the outside surface of drip irrigation tape by deforming the strip of flexible material when it is in a semi-molten state and cooling the strip while it is deformed. The indicia may include alphanumeric characters, logos or symbols that convey information. Indicia forming features in the surface of a shaping drum mold the strip of semi-molten material as the semi-molten material cures to form a flexible strip. The flexible strip is folded and sealed to form the drip irrigation tape.

  • Patent number: 6442843
    Abstract: A knife and sheath assembly includes a knife having a handle and a blade and a sheath having a cavity for releasably receiving the knife blade in a storage condition. A first end portion of the blade is adjustably mounted in the handle and a second end portion including a cutting edge protrudes from the handle. The blade is movable between a first, retracted position in which a first length of the blade protrudes from the handle and a second, extended position in which a second length of the blade longer than the first length protrudes from the handle. A releasable latch member on the handle releasably locks the knife blade in the first and second positions, and the sheath cavity is designed to receive the portion of the knife blade which protrudes from the handle in the retracted position, such that the overall length of the assembly is reduced when the knife is sheathed.

  • Patent number: 6439229
    Abstract: A system and method of controlling the termination of the inhalation phase in a pressure support ventilation system is disclosed, in which an expiratory trigger sensitivity, or ratio of inspiratory flow rate to peak inspiratory flow rate at which the inspiration phase is terminated, is varied in proportion to variations in a calculated respiratory time constant. The system includes sensors for monitoring pressure and flow of gas during each breath, and, based on the sensor outputs, calculates the respiratory time constant for one breath or a series of breaths. The expiratory trigger sensitivity is automatically increased with increasing patient respiratory time constant, providing a closed loop control of expiratory trigger sensitivity. The expiratory trigger sensitivity may also be varied in response to changes in supra-plateau pressure.
