  • Patent number: 6360369
    Abstract: A system for the removing of interference (ingress) in cable modems without reducing the data rate or changing the frequency of the signal. The invention comprises both, a variable band stop filter bank, and a non-linear equalization system. The band stop filter bank removes ingress while the equalization system, comprising of an inner and an outer equalizer, removes the distortion created by the band stop filtering. A spectrum monitor detects both the presence of ingress and its frequency, then feeds the data to a digital signal processor which calculates the distortion removal settings for the equalizers. No additional hardware of software is required in the users homes, but rather the invention is designed to be used solely at the head end and in addition to the basic Cable Modem Termination System.

  • Patent number: 6033484
    Abstract: A method for cleaning contaminated surfaces, especially semiconductor wafers, using energetic cluster beams is disclosed. In this system, charged beams consisting of microdroplets or clusters having a prescribed composition, velocity, energy and size are directed onto a target substrate dislodging contaminant material. The charged, high energy cluster beams are formed by electrostatically atomizing a conductive fluid fed pneumatically to the tip of one or more capillary-like emitters. The high extraction field necessary for atomization and formation of charged clusters, on the order 10.sup.5 volts/cm or greater, is provided by applying a potential difference between the emitters and a counterelectrode. Since the charged clusters, typically 0.01 to 0.1 micron in diameter, are multiply charged, acceleration through 10 kV or more results in large substrate impact energies greater than 0.5 million electronvolts.

  • Patent number: 5681457
    Abstract: A unit for removal and prevention of scale deposits in a preexisting fluid containing system and destruction of microbes. The invention utilizes a.c. and d.c. superimposed electrical fields in combination with a sonic or ultrasonic transducer for supplying electrical and mechanical energy into a colloidal or particulate-containing solution. An impure fluid stream of reduced conductivity is passed between a cylindrical insulated electrode, having a first end and a second end, which electrode is axially centered within an insulated cylindrical electrode and housing. The configuration of the electrodes form a sealed cylindrical treatment chamber, having a inlet and an outlet for a fluid stream, and provide an electric field of a.c. waveforms superimposed on d.c. waveforms, comprising a resultant ripple voltage waveform. The ripple voltage is obtained by rectifying and filtering a standard and commercially available a.c. voltage.

  • Patent number: 5431518
    Abstract: An integral nut and washer formed from a fiber reinforced polymeric material that is particularly useful for use in water tanks and the like that are bolted together from overlapping metal plates. The combination includes a generally cylindrical nut body having an internally threaded cavity, with a transversely extending washer portion around the opening. At least one pair of opposed flats are provided on the nut body for tightening the nut with a conventional wrench. An axial vent is provided at the closed end of the cavity to allow air or excess sealant, where sealant is used, to escape as the nut is tightened. The entrance into the threaded cavity is chamfered, and the washer portion is tapered back along the nut portion for maximum washer strength. Preferably, the integral nut and washer is formed from a glass fiber reinforced polyurethane material by injection molding. This nut is durable and does not corrode in use.

  • Patent number: 5251761
    Abstract: A method of handling recyclable materials through the use of distinctive, and relatively rugged plastic bags is provided. Such bags are furnished to one or more communities as part of a recycling program. The bags preferably include source identification codes particular to each community. The bags are filled with recyclable materials, closed, and left at curb side or other location for pick up by collection equipment. The bags, which may be comingled with other, non-recyclable waste materials, are gathered and compacted in order to reduce the volume thereof. The rugged construction of the bags ensures that a relatively high percentage survive the compaction process without spilling the materials contained therein. Bags are then transported to a delivery point where they are separated from other comingled waste materials. Bags may then be emptied and the materials contained therein recycled.

  • Patent number: 5072833
    Abstract: The present invention concerns a method of collecting recyclable materials and separating recyclable materials from household and commercial refuse for recycling at a recyclable material recovery facility. The method comprises placing recyclable material into a flexible receptacle or container having a rugged construction sufficient to withstand forces experienced under compaction, transfer and dumping, during curbside pick-up, delivery along with mixed solid waste to a delivery point and transferral to a picking station of a solid waste facility. Each flexible receptacle has a predetermined color rendering the flexible receptacle highly visible against and distinguishable from other solid waste. The flexible receptacle is delivered to the delivery point for transferral to a picking station solid waste facility, for the purpose of recycling the recyclable material placed therein.

  • Patent number: 4896035
    Abstract: An improved ion detection system and method for detection of low or high mass ions. A target having a low work function, photoemissive surface layer is employed to fragment the incident ions and produce secondary negative ions and electrons. The target surface preferably is formed of a thin layer of an alkali antimonide compound, bialkali antimonide compound, multi-alkali antimonide compound, cesiated III - V semiconductor compound, or other photoemissive material having a relatively low band gap energy and electron affinity. Additionally, the photoemissive material should have a low thermionic emission level at room temperature to reduce noise levels in the detector. The secondary ions and electrons may be detected by a conventional electron multiplier detector. The potential difference between the target surface and electron multiplier detector is chosen to accelerate the secondary ions and electrons to the electron multiplier detector with an energy corresponding to high detection efficiency.

  • Patent number: 4835383
    Abstract: An improved ion detection system and method for detection of low or high mass ions having high electron affinity constituent atoms or molecules. A target with a low work function target surface is employed to fragment the incident ions and produce secondary negative ions and electrons. A cesium or barium oxide source is employed to optimally provide a monolayer of cesium or barium oxide on the target surface of a molybdenum or tungsten target. The secondary ions and electrons are detected by a conventional electron multiplier detector. The potential difference between the target surface and electron multiplier detector is chosen to accelerate the secondary ions and electrons to the electron multiplier detector with an energy corresponding to high detection efficiency.

  • Patent number: 4805189
    Abstract: A signal processing system for measuring the amplitude and time delay responses of a network over the bandwidth allocated to the network wherein a plurality of subburst signals each in the form of a suppressed-carrier, amplitude-modulated signal, is applied to the network. The signals received from the network are provided in complex form having in-phase and quadrature components. Matched filters respond to such components and the matched filter outputs are processed so as to determine the estimated amplitude and time delay responses of the network at the carrier frequency of the subburst signals over the operating bandwidth of the network.

  • Patent number: 4762975
    Abstract: A process for producing ultrafine particles includes the steps of providing a consumable electrode having a rod or wire configuration, melting the tip of the electrode by means of electron bombardment, and applying an intense electric field to the molten tip to generate a beam of charged droplets. By heating the tip of the rod but avoiding melting of the tip and subsequently applying an electric field to the heated tip, an ion beam may be generated.
