  • Patent number: 9903788
    Abstract: An apparatus includes an electroactive polymer member and a first electric terminal and a second electric terminal. The electroactive polymer member has a free portion configured to change position relative to a fixed portion in response to an external stimulus corresponding to at least one of a flow parameter or a fluid parameter. The first electric terminal and the second electric terminal are coupled to the electroactive polymer member. The first electric terminal and the second electric terminal provide an electrical signal in response to the change.

  • Publication number: 20110010074
    Abstract: A method for controlling the start of combustion and peak burn rate of an internal combustion engine system on a cycle-to-cycle basis including multiple direct fuel injectors, multiple indirect fuel injectors, and multiple liquid fuels. The actual start of combustion and actual peak burn rate are calculated using in-cylinder pressure or ionization. A predetermined start of combustion and a predetermined peak burn rate are selected. The start of combustion and peak burn rate control algorithm includes controlling a fuel ratio, an injection ratio, and a residual gas recirculation ratio. A predetermined fuel ratio, a predetermined injection ratio, and a predetermined residual gas recirculation are calculated by combining feed forward ratios and closed loop control ratios corresponding to the three ratios. The predetermined ratios are employed so that the system achieves the predetermined start of combustion and predetermined peak burn rate.

  • Patent number: 7840458
    Abstract: A method and apparatus for collecting information about an event in which a user accesses the Internet through the system of a first Internet Service Provider with whom the user does not have an account. The apparatus includes a first server that creates a record of the user's Internet usage and sends the record to a second server. The second server collects records from a plurality of Internet Service Providers and forwards the records to a third server on a regular basis. The third server processes the data in the plurality of records and generates a report showing how much money the first Internet Service Provider is owed for allowing the user to access the Internet through the system of the first Internet Service Provider.

  • Publication number: 20090090794
    Abstract: A low pressure fuel injector capable of atomizing fuel at relatively low pressure is configured to have reduced hydraulic resistance. Reduction in the hydraulic resistance minimizes the pressure drop within the fuel injector and thereby improves atomization of the fuel for improved fuel economy and performance, and decreased emissions.
