Abstract: Certain aspects of the disclosure relate to combining uplink and downlink location technologies into a single location-service system, to obtain the benefits offered by both of technologies while eliminating many of their individual shortcomings. Mobile devices that support downlink can then be located using the downlink mode, and mobile devices that do not support downlink can be located using the uplink mode. A mobile device may even be located based on a combination of uplink measurements and downlink measurements. Other aspects of the disclosure relate to providing a single location-service system to locate mobile devices that communicate using a plurality of different communication protocols.

Abstract: In one embodiment of the present invention, a method includes connecting a wireless device to a network via a first connection and enabling a lower usage level for the wireless device if a throughput of the first connection is below a predetermined threshold.

Abstract: An intake manifold for a four-cycle internal combustion engine with multiple stages to reduce imbalances in volumetric efficiency and air/fuel ratio. The intake manifold utilizes at least two ram stages coupled by a plenum chamber. The first stage includes a ram tube that carries the air/fuel mixture from the carburetor, or throttle body to the plenum chamber. The second stage includes at least two ram tubes that carry the air/fuel mixture from the plenum to a plurality of intake valves through cylinder head intake ports. The plenum chamber acts as a buffer between each intake valve and the carburetor or throttle body. The air/fuel mixture enters the first stage ram tube and passes into the plenum chamber. These gases then pass into either one of the second stage ram tubes, depending on which cylinder is at its intake stroke. By drawing the air/fuel mixture from the plenum instead of directly from the first stage ram tube, differences in the air/fuel ratio and volumetric efficiency are minimized.

Abstract: A cylinder head for a four-cycle internal combustion engine with improved intake port and combustion chamber configuration. The physical shape of the intake port and combustion chamber directs the flow of the incoming air/fuel mixture in a swirl path, which is directed toward the spark plug. In particular, the intake port has a fin at its terminal opening into the combustion chamber. The fin creates a swirling motion in the incoming gasses and also directs the flow of the gasses toward the spark plug. As a result, a greater percentage of the intake charge is in close proximity to the center of the combustion chamber and the spark plug, and hence combustion occurs faster and more completely. In a preferred embodiment of the invention, the portion of the cylinder head that forms the upper surface of the combustion chamber, includes a shear ledge that further acts to direct the flow of the incoming gasses toward the sparkplug.

Abstract: The present invention defines a precision primer-reloading assembly to be mounted in and operated by a suitable cartridge-reloading press. The assembly includes a tubular support-body member having a ram rod mounted therein so as to be positioned within the cartridge case at the time the primer is loaded. The support-body member is mounted to the reloading press above and in alignment with a primer-guide assembly which is mounted to the press ram of the reloading press. The guide assembly includes a guide base having a primer-guide pin. A coil spring is positioned on the guide base so as to engage the guide housing that is slidably mounted over the guide base, the guide housing being formed with a closed end having a centrally positioned recess. This recess is provided to support and align the cartridge case with the ram rod, whereby the primer can be loaded in the primer pocket of the case by means of the primer pin as the ram rod is activated.
