Abstract: A switching circuit (Q11, Q12, D11, D12, D13, L11, L12) is repetitively configured to charge an energy transfer capacitance (C11) from an electrical supply (V11) and then inject a discrete pulse of energy into a resonated load circuit by discharging the capacitance. The load circuit is formed by a resonating capacitance (C12) and an inductive load device (T11, R11), eg motor, or induction heating or power transfer device. Energy circulates in the load circuit at or near to its natural resonant frequency. There is no injection of energy into the load circuit while energy for charging the transfer capacitance is being delivered from the supply to the switching circuit. During injection, the two capacitances and the inductive load device may be connected together in parallel or in series, or the transfer capacitance may be connected in series with the inductive load device but not the resonating capacitor.

Abstract: A method is provided including determining a first power level required from a diesel powered system. The first power level corresponds to a first proportion of a maximum power. The method also includes determining an emission output for a mission based on the first power level. The method further includes determining a second power level corresponding to a second proportion of the maximum power, wherein alternate use of the second power level and at least one of the first power level or a third power level results in a lower emission output for the mission, with the overall resulting power being proximate the minimum power required. The method also includes automatically controlling operation of the diesel powered system by using the second power level alternately with at least one of the first power level or the third power level.

Abstract: A system and process is presented that identifies nearby objects and/or points in relation to a base object or point. An object or point is nearby if it resides within a prescribed area around the base point. The identification is based on information accessed from a database of geometric data. The identification of nearby neighbors begins by dividing the geographic system defined by said geometric data into a plurality of zones. The zone in which each object or point resides and the zones intersected by the prescribed area are determined. The nearby objects and/or points of interest are then identified by initially considering only those that are identified as residing in the zones intersected by the prescribed area. The search for nearby neighbors can be further refined by limiting the objects and/or points considered to those with locations within the lateral extent and/or within the height of the prescribed area.

A latching unit is disposed in the cavity of the sled body along with a spring that is configured to hold the latching unit in a locked position. A latch cover covers the cavity of the sled body. At least one of the latch cover or sled body includes an opening that allows an operator to manipulate the latching unit to an unlocked position.

Abstract: A viscosity modifying agent is added to a concrete mixture to give the concrete desirable rheological properties. The viscosity modifying agent is incorporated into a foam admixture before it is mixed into the concrete. Because the viscosity modifying agent is a component of the foam admixture, the viscosity modifying agent is dispersed in the aqueous film that forms the foam bubbles. The viscosity modifier in the foam bubbles gives the foam beneficial rheological properties. The viscosity modifier performs more efficiently when included in the foam bubbles as compared to being mixed directly into the concrete. The foam bubbles containing the viscosity modifier can be stabilized using a fluorochemical stabilizer, which is included in the foam admixture. The foam bubbles can be further stabilized with respect to cement mixtures by including a hydration stabilizing in the cement mixture.

Abstract: A system and method for enhanced data connections via an asymmetric data network receives incoming modem calls and discriminates those intended for enhanced service Web or other service, for instance by domain name. Those calls destined for that type of enhanced treatment may be received via modem banks or other RAS resources communicating with the PSTN or otherwise, and directed to an enhancement cluster or other nodes or locations for compression, caching, optimization or other processing designed to give the user's Web browsing or other service an improved or more responsive feel. According to embodiments of the invention in one regard, the user IP sessions may be tunneled to the enhancement cluster using a tunneling protocol, such as Layer 2 Tunneling Protocol (L2TP) or others.
