  • Publication number: 20090166223
    Abstract: The present invention is based on the discovery of NAD+ and NADP+ mediator compounds that do not bind irreversibly to thiol groups in the active sites of intracellular dehydrogenase enzymes. Such mediator compounds avoid a common mode of enzyme inhibition. The mediators can therefore increase the stability and reliability of the electrical response in amperometric electrodes constructed from NAD- or NADP-dependent enzymes.

  • Patent number: 7434818
    Abstract: The “One-Hand Operation Conversion for Wheelbarrow Handles” added to a wheelbarrow, on one hand, offers single hand operability and maneuverability, and on the other hand offers added benefits to dual-handed users. The wheelbarrow can easily be converted from dual to single-handed operation and then back again with this said unit. This is completed by adding a centrally mounted handle to cross support(s) which are attached to the two longitudinally extending handles of the said wheelbarrow. When the center handle is attached, one-hand operation is achieved by the load balancing capabilities of the said handle and its mounting orientation. The center handle is formed into or mounted to the cross support(s) that are mounted to the existing longitudinal handles. The unit size dimensions and mounting method are arbitrary and will be made to fit the circumstances of mounting position and cross support material. The cross support(s) material and the handle material are of variable rigid form.

  • Publication number: 20060273183
    Abstract: A method for dehumidifying air in an indoor space using outside air is comprised of the steps of: sensing whether there is a demand for dehumidification in the space; in response to a demand for dehumidification, determining whether outdoor air is suitable for dehumidification of the space; if the outdoor air is determined to be suitable, admitting outdoor air into the air supplied to the space; and selectively temperature conditioning the supply air in accordance with a predetermined temperature condition therefor. The method is disabled in response to a demand for heating or sensible cooling in the space. Further, the ratio of outdoor air to return air in the supply air is kept relatively constant, irrespective of whether the predetermined temperature condition is satisfied.

  • Patent number: 6990256
    Abstract: An optical modulator includes first and second modulator segments. The first and second modulator segments form an optical signal path for an optical signal. The optical modulator also includes an electrical signal path capable of receiving and carrying a modulation signal, which is applied to the optical signal at the first and second modulation segments to generate a modulated optical signal. An inductive element may be disposed between electrical inputs to the first and second modulator segments. The optical modulator may be an electro-absorption modulator (EAM). The inductive element may be an inductor or a transmission line segment.

  • Publication number: 20040225733
    Abstract: A message is multicast to recipients by correlating the message at a management system to agents, each agent being responsible for a set of the recipients, and by conveying the message over a network to the correlated agents for transmission to the recipients. The management system maintains recipient lists wherein each list is associated with one or more agents, each agent maintaining a portion of its associated lists. The management system chooses a single recipient list and conveys an indication of the list to its associated agents. Each notified agent accesses the indicated list and sends the message to the listed recipients. In a further embodiment, an independent management system interfaces a plurality of management systems, each with a set of agents. The independent management system chooses a recipient list, the list being associated with a management system and its agents, and conveys the message based on the chosen list.

  • Patent number: 6778309
    Abstract: An electroabsorption modulator comprises a tandem arrangement of a conventional electroabsorption (EA) modulator element and a phase modulator element. The EA modulator element is driven by the digital data signal and the phase modulator is driven by a chirp tuning control signal, such as the complement of the data signal. By controlling the amplitude and/or bias of the chirp tuning control signal, the frequency chirp of the intensity-modulated output signal from the EA modulator element can be controlled.
