Abstract: A firearm has an emitter that propagates a light beam to a receiver and at least two finger position beams that propagate horizontally along the firearm on either side of a switch that provides detection of a position of a finger when the finger blocks and unblocks the finger position beam. Further, when only two finger position beams are blocked, this indicates proper positioning of the finger placing the firearm into a dischargeable condition.

Abstract: The present invention describes a fuel-management system for minimizing particulate emissions in turbocharged direct injection gasoline engines. The system optimizes the use of port fuel injection (PFI) in combination with direct injection (DI), particularly in cold start and other transient conditions. In the present invention, the use of these control systems together with other control systems for increasing the effectiveness of port fuel injector use and for reducing particulate emissions from turbocharged direct injection engines is described. Particular attention is given to reducing particulate emissions that occur during cold start and transient conditions since a substantial fraction of the particulate emissions during a drive cycle occur at these times. Further optimization of the fuel management system for these conditions is important for reducing drive cycle emissions.

Abstract: An end treatment for use with an ultrasonic gas flow meter includes an attenuation section having a pipe extending in a longitudinal direction and containing alternating sets of laterally spaced and vertically oriented first and second solid wall plates located between an inlet end and an outlet end of the pipe. One plate includes a first end connected to an inside wall of the pipe and another plate includes a second end that extends past a longitudinal centerline of the pipe to define a gap between the end of the plate and a respective opposing inside wall of the pipe. As the gas traverses the plates by flowing through the gaps, the ultrasonic waves are prevented from reflecting back to the flow meter.

Abstract: Contextual awareness associated with resources can be employed to facilitate controlling access to resources of a system, including function blocks. A resource manager component (RMC) can pre-load a defined number of respective versions of configuration parameter data associated with respective applications in each resource. With regard to each application, the RMC can associate a context value, unique for each application, with the respective versions of configuration parameter data associated with that application. When a current application is being changed to a next application, the RMC can write the context value associated with the next application to a context select component (CSC). Each resource can read the context value in the CSC, identify and retrieve the version of configuration parameter data associated with the next application based on the context value, and configure the function block based on the version of configuration parameter data.
