Abstract: Disclosed herein is a novel electric motorcycle charging stand and methods of using such a novel electric motorcycle charging stand for charging an electric motorcycle. Such stands present an opportunity to include functionality for storing energy and incorporate electronical components in the stand to charge electric motorcycles when not in use. In one embodiment a detached motorcycle stand can be arranged to stores electrical energy (for example, via an electrical energy storage element) and enables charging of an electric motorcycle (for example, via a charging enablement element). Thus, energy can be stored when there is convenient access to the electrical power grid and the electric motorcycle can then be charged in environments and locations that do not have ready access to the electrical grid.

Abstract: A system is provided for automatically shutting down an engine in response to the engine operating while in an enclosed space to prevent dangers associated with carbon monoxide accumulating in the enclosed space. The engine has an oxygen sensor in its exhaust that is configured to detect oxygen in the exhaust or ambient. A controller can be programmed to shut down the engine based on a determination that the engine is operating in a confined or enclosed space by analyzing a rate of change of the oxygen content in the exhaust or ambient, and compares the rate to a threshold. The shutdown may be commanded if the rate exceeds the threshold. In some embodiments, the shutdown may additionally be in response to a temperature of the ambient air or intake air increasing, which furthers the confidence of the determination that the engine is operating in a confined or enclosed space.

Abstract: A system is provided for automatically shutting down an engine of a portable or handheld device in response to the engine operating while in an enclosed space, such as a garage, shed, room, etc. to prevent dangers associated with carbon monoxide accumulating in the enclosed space. The engine has an oxygen sensor in its exhaust that is configured to detect the presence or absence of oxygen in the exhaust. Fuel can be removed from the air/fuel mixture (e.g., less fuel being injected) based on the output of the oxygen sensor to maintain a given desired air/fuel ratio. If the amount of fuel provided continues to decrease over time in order to maintain the air/fuel ratio, the controller can assume the engine is operating in confined spaces and can shut down the engine.

The engine has an oxygen sensor in its exhaust that is configured to detect the presence or absence of oxygen in the exhaust. A fuel injector injects fuel for combustion within the combustion chamber. The oxygen sensor may be a switch producing an associated frequency indicating the presence or absence of oxygen. This frequency can control the fuel injection duration such that as the frequency of switching decreases, the injector injects less fuel. If the frequency continues to decrease even while injection is reduced, the controller can assume the engine is operating in confined spaces and can shut down the engine.
