An engine includes a piston slidably disposed in a cylinder with a closed end. The engine further includes a converter operable with the piston to convert mechanical energy of the piston to electrical energy in the converter in a stroke and convert electrical energy of the converter to mechanical energy in the piston in at least one other stroke.
摘要:
A method of retrofitting for electrical power generation an internal combustion engine (including a plurality of pistons connected to a common crankshaft) includes applying to at least one and optionally to each piston a power converter operable to convert mechanical energy of the piston to and from electrical energy.
摘要:
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.
摘要:
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.

Techniques for ability enhancement are described. Some embodiments provide an ability enhancement facilitator system (“AEFS”) configured to enhance a user's ability to operate or function in a transportation-related context as a pedestrian or a vehicle operator. In one embodiment, the AEFS is configured perform vehicular threat detection based at least in part on analyzing image data. An example AEFS receives data that represents an image of a vehicle. The AEFS analyzes the received data to determine vehicular threat information, such as that the vehicle may collide with the user. The AEFS then informs the user of the determined vehicular threat information, such as by transmitting a warning to a wearable device configured to present the warning to the user.
摘要:
Techniques for ability enhancement are described. In some embodiments, devices and systems located in a transportation network share threat information with one another, in order to enhance a user's ability to operate or function in a transportation-related context. In one embodiment, a process in a vehicle receives threat information from a remote device, the threat information based on information about objects or conditions proximate to the remote device. The process then determines that the threat information is relevant to the safe operation of the vehicle. Then, the process modifies operation of the vehicle based on the threat information, such as by presenting a message to the operator of the vehicle and/or controlling the vehicle itself.
