  • Patent number: 6137865
    Abstract: A network interface for home networking implemented upon an existing 4-wire (two-pair) phone line system is disclosed. The interface comprises two transmitters, two line isolators and a receiver. The two transmitters transmit data simultaneously to both of the pairs of wires in the phone line system so that all devices coupled to the phone line system, regardless which pair of wires being coupled onto, can receive the data. Because all the pairs carry the data, there is therefore needed one on receiver in the interface to receive the data transmitting over the phone line system. The disclosed interface provides a solution to the home networking which no longer requires the knowledge of the underlying wiring structure in the phone line system.

  • Patent number: 6110195
    Abstract: A method and apparatus for surgical and dermatological treatment using a multi-wavelength laser system includes a primary laser beam generator optically pumped by a semiconductor laser diode. A portion or all of the optical pumping energy may be outputted with the primary laser beam output to form a multi-wavelength treatment beam. A frequency doubling medium, such as a KTP or LBO crystal, may be imposed in the output of the laser beam generator to produce an additional wavelength that may be combined into the multi-wavelength treatment beam. To achieve high peak power pulse laser output, a Q-switch element can be placed in front or in back of the laser crystal. Alternatively, the laser system may output only the wavelength of the semiconductor laser diode pumping system. The selection of one or more wavelengths provides a wider range of treatment modalities using a single laser system, without creating problems attendant with the complexity and maintenance of prior art multi-wavelength laser systems.

  • Patent number: 6083383
    Abstract: This invention relates generally to apparatuses and processes for preparing fibrinogen glue from autologous plasma. More particularly, this invention relates to a novel apparatus comprising a plasma membrane separator to extract and separate the autologous plasma from other undesirable compositions in the blood. The autologous plasma is transferred to a membrane separator to provide separation of the fibrinogen from other compositions with a desirable amount of ether or other suitable solvents containing an-OH group in the presence of a mixing means. The fibrinogen so separated is transferred to a fibrinogen collector which is connected to a vacuum pump through a sterile filter to remove the ether or other suitable solvents contained thereof. A freezer is provided to maintain the autologous plasma in the membrane separator and the fibrinogen in the fibrinogen collector at a desirable temperature.
