  • Patent number: 6491609
    Abstract: An exercise arm apparatus has a stationary frame member, a first pivoting arm pivoted to the frame member at a location intermediate its ends for rotation about a first pivot axis, a second pivoting arm pivotally connected to the frame member for rotation about a second pivot axis spaced from the first pivot axis, and a connecting link pivotally connected to the first arm and second arm to form a four-bar linkage. The first arm is an exercise arm with handles at one end for gripping by a user, and the connecting link is of sufficient weight to form a counter-weight to counter-balance the first exercise arm into a rest position corresponding to a start position for an exercise movement. In one example the connecting link is a solid, elongate bar of heavy metal or equivalent material.

  • Patent number: 6490374
    Abstract: The method identifies a Pixon element, which is a fundamental and indivisible unit of information, and a Pixon basis, which is the set of possible functions from which the Pixon elements are selected. The actual Pixon elements selected from this basis during the reconstruction process represents the smallest number of such units required to fit the data and representing the minimum number of parameters necessary to specify the image. The Pixon kernels can have arbitrary properties (e.g., shape size, and/or position) as needed to best fit the data.

  • 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: 6455779
    Abstract: A cover for a connector of a cable is disclosed, which has two interfitting sleeves which are chemically swellable and which are initially in dilated configuration, and which subsequently shrink into place by evaporation of a volatile swelling solvent. Both sleeves are made of a high density elastomeric material, such as a natural or synthetic rubber, preferably (EPDM), neoprene or chlorosulfonated polyethylene rubbers. The device provides a protective cover for a cable connection or splice which can be easily installed, quickly shrunk into tight vapor resistant protective covering within a matter of a few minutes, and can be installed without the need for any application of heat or use of special tools, equipment or materials.
