  • Patent number: 6256124
    Abstract: A delayed-pulse photonic time division multiplexer which provides a parallel digital data to photonic serial conversion is disclosed. Modifications which provide wavelength division multiplexing are also included. A series of input pulses of photonic energy are directed into an output as sync pulses. The input pulses are also directed into a group of n optical modulators to read parallel digital data that has been loaded into the modulators. Modulator outputs are delayed by digit-transmission-time intervals and directed into the output as serial data between the sync pulses. Input pulses are also used to trigger the loading of the next data set into the modulators during the time that the previous data set is being transmitted in serial. The invention can send serial data at the maximum speed of optical components while using data from slower electronic components.

  • Patent number: 5572528
    Abstract: An internetwork including a plurality of local area networks may include wireless and hard-wired local area networks. The internetwork may also include wide area network links between routers. The system includes routers between networks, which may be bridged networks. Certain routers are configured as home routers. Home routers bind two addresses for each mobile node on a given network when that node logs-in with a home router. Mobile nodes log-in with a home router that assigns a virtual address that does not change throughout a session. Each time, a mobile node roams to another network across a router boundary, the virtual address remains the same and all packets directed to the mobile node are received by the home router which advertises that it can reach the mobile node. As the mobile node roams, it reports back to the home router a local address to which the home router forwards all packets directed originally by correspondent nodes to the virtual address.

  • Patent number: 5566395
    Abstract: A disposable liner is fitted against the inside surface of a sweatband of a cap or hat. The liner functions to absorb moisture and oils, and to eliminate odor. The liner wicks moisture away from a user and may hold moisture away from the hat. The liner may wick moisture to an evaporation region to be evaporated. The evaporation region may be separated from the hat by a cover layer to prevent wicking into the crown of the hat. The liner may be configured to adjust the size, and thus the fit of the hat on the head of the user. To secure a hat on the head of a user, the liner may include a compressible, foamed, polymeric core. The core may be treated with an antibacterial agent and a deodorizing agent for eliminating odors. To one side of the core is attached an adhesive layer for securing the to the sweatband of the hat. The adhesive is selected for firmness yet easy removal and disposal of the liner. The adhesive may be heat-sensitive.

  • Patent number: 5565199
    Abstract: Systems and methods for synthesizing natural base steroidal hormones and more especially estrogens and progesterone and estrogen-like and progesterone-like compounds and their derivatives which are derived in the form of phytohormones from herbaceous plants and formulated to provide a broad spectrum of estrogenic and/or progesterone activity for influencing physiological processes and biological functions. In particular, phytohormones (i.e. phytoestrogens and/or phytoprogesterone) are synthesized from herbaceous compounds selected from a group consisting of plants having a propensity for simulating estrogenic and/or progesterone hormonal activity that, when entering the bloodstream of a biological organism, either by means of oral ingestion, parenteral injection, or topical application, have a tendency to enhance, supplement and/or maintain estrogen and/or progesterone hormonal levels by means of replacement therapy within a biological organism.

  • Patent number: 5544844
    Abstract: An autogyro has a teetering semi-rigid rotary wing with rigid rotor blades. The angle of attack (blade pitch) of the rotor blades is fully adjustable in flight continuously over an operational range, and varies along the blade length. A prerotator rotates the rotor blades up to takeoff speed at minimum drag, no lift and optimum engine efficiency. Engine power is disconnected from the rotor blades and their angle of attack is changed for optimum lift to facilitate smooth vertical takeoff. Rotor blade pitch is likewise adjusted during vertical landing. In flight, rotor blade angle of attack is varied to adjust autorotation, lift and drag at any flight airspeed. On the ground, the rotary wing is braked to prevent rotation.The autogyro may roll, pitch, or yaw, with complete independence of blade pitch with respect to all other relative motions. The pedals have disproportionate forward and backward motions. The autogyro has retractable gear capable of fail-safe gear-up landing.

  • Patent number: 5485637
    Abstract: A tank for liquidous material is disclosed having a single aperture for accessing an interior volume. A collar formed as a truncated cone circumscribes the aperture to provide sealing with a cap having a mating conical band. A band surface and a collar surface form the only contact between the cap and the collar. A drain fitting may be secured to the collar upon removal of the cap, after which the tank is upended for draining through the drain fitting. A wash fitting attached to the drain fitting sprays the interior of the tank for cleaning. No recesses (grooves) or `O` ring seals, and no protruding, resilient, normal, face seals are used which might trap debris and inhibit complete cleaning. The tapered collar and band create contact forces for sealing that are much greater than the load securing the cap to the collar. The tank, collar and cap may be rotomolded of a single material in a single mold, the cap being severed and trimmed after molding.
