Abstract:
Methods of operating an internal combustion engine are disclosed that may include a first piston slidably disposed in a first cylinder having a first and a second closed end, and a first converter operable with the first cylinder. The first converter may be configured to convert mechanical energy to electrical energy, and vice versa. As a non-limiting example, such disclosed embodiments may be used to convert mechanical energy of the first piston to electrical energy during a power stroke, and to drive the first piston during one or more of an exhaust stroke, an intake stroke, or a compression stroke.
Abstract:
A beam power source transmits a signal indicating power availability, receives a request for power in response, and beams power in response to the request.
Abstract:
In an embodiment, an internal combustion engine includes a first cylinder having a first piston and a second piston slidably disposed therein, an intake port arranged to admit a reactant into the first cylinder between the first and second pistons, and an exhaust port axially spaced from the intake port and arranged to exhaust a reaction product from the first cylinder. First and second converters are provided, which are operable with the corresponding first and second pistons, to convert mechanical energy of the first and second pistons to electrical energy and electrical energy to mechanical energy. A control system is provided that is coupled to the first and second converters. The control system is configured to control the application of electrical energy to the first and second converters to selectively position the first and second pistons during specific strokes of the engine cycle.
Abstract:
An electrochemical device (such as a battery) includes at least one electrode having a fluid surface, which may employ a surface energy effect to maintain a position of the fluid surface and/or to modulate flow within the fluid. Fluid-directing structures may also modulate flow or retain fluid in a predetermined pattern. An electrolyte within the device may also include an ion-transport fluid, for example infiltrated into a porous solid support.
Abstract:
One aspect relates to a method of reducing noise for an aircraft. The method includes determining a mode of operation of the aircraft or the engine. The method also includes controlling a hybrid jet engine, based on the mode of operation, to at least partially use electrically generated torque to generate thrust.
Abstract:
One aspect relates to a hybrid propulsive technique, comprising providing at least some first thrust associated with a flow of a working fluid through at least a portion of an at least one axial flow jet engine. The hybrid propulsive technique includes extracting energy at least partially in the form of electrical power from the working fluid, and converting at least a portion of the electrical power to torque. The hybrid propulsive technique further includes rotating an at least one substantially axial-flow independently rotatable compressor rotor at least partially responsive to the converting the at least a portion of the electrical power to torque.

Abstract:
Configuration technologies for apportioning resources and communicating indications of potential or actual incentives based on one or more measurements or other objective indications that therapeutic components have been administered to an individual, other attributes of the therapeutic components or the individual, or other such determinants. Techniques for apportioning resources cost-effectively (between providers and other parties, e.g.) and for facilitating or handling implementations thereof or output therefrom.
