Abstract: Embodiments are directed to managing user interactions with applications. Entry point information may be provided to an application installed on a client computer. Application information may be obtained from a measurement engine based on the provided entry point information. One or more portions of the application information may be selected based on one or more characteristics of the client computer. An application view of the application may be provided for display on the client computer based on the one or more selected portions of the application information. One or more application metrics associated with the application and the one or more selected portions of the application information may be collected. The one or more collected application metrics may be provided to the measurement engine.

Abstract: In some embodiments, a tracking system is provided for providing credit to advertisers for application installs and in-application events. The tracking system may be configured to use user account information from a content provider system to determine whether a user of a newly installed application is a new user of the content provider system or an existing user of the content provider system, and to update tracking information accordingly. The tracking system may also use the user account information from the content provider system to link actions on multiple computing devices for the purposes of attributing a given application install to one or more advertising providers.

Abstract: Systems and methods for attributing actions on an end user computing device to an advertising publisher without using persistent storage or cross-process communication on the end user computing device are provided. In some embodiments, multiple types of credit for a single application installation may be provided to multiple advertising providers. Credit for attributed installs, install assists, and non-windowed install contributions may be provided. In some embodiments, credit may be adjusted after an initial processing of a conversion based on information received after the initial processing of the conversion, while still maintaining consistency in summary reports.

Abstract: A variable phase shifter and a system for the variable phase shifter are provided. The phase shifter includes fixed phase shift elements, active devices for amplifying the outputs of the fixed phase shift elements, a combiner for combining the outputs of the active devices. For controlling the phase of the output signal, a bias controller is provided. The bias controller controls the bias of amplification in the fixed phase shift elements. The active devices may be FET or Bipolar Transistors, and are inductively connected to the ground. The phase shifter can be integrated into a system on chip with a smart antenna front-end system.

Abstract: The present invention is a method and apparatus to clean the intake system of an internal combustion engine including the intake valves. An air metering block is connected to the intake manifold of the engine by means of an adaptor tube. The only air that can get into the intake manifold of the engine is through inlet ports in the air metering block. An air adjusting screw selectively uncovers the inlet ports to vary the amount of air which can be introduced into the intake manifold. An electrically operated injector is fitted in the air metering block to inject solvent directly into the intake manifold. An adjustable injector driver varies the duty cycle or the on time of the injector to control the amount of flow of solvent into the intake manifold. A pumping unit is provided to pump solvent from a holding tank, through the injector, into the intake manifold.
