Abstract: A convertible carriage for transporting subjects on a plurality of operating surfaces. The convertible carriage includes a receptacle, a sledge attached to the receptacle, a set of wheel assemblies, and a set of telescopic landing gears attached to the receptacle, and connected to the wheel assemblies. The telescopic landing gears are configured to operably extend or retract to switch the convertible carriage between a rolling operation mode and a sliding operation mode. In the rolling operation mode, one or more wheel assemblies from the set of wheel assemblies are in contact with the operating surface such that the convertible carriage is transportable on an operating surface by rolling of the wheel assemblies. In the sliding operation mode, the set of wheel assemblies are retracted to allow the sledge to contact with the operating surface such that the convertible carriage may be transportable on the operating surface by sliding.

Abstract: Methods and systems are provided for expediting heating of an engine and an emissions device upon cold startup of the engine. In one example, a method may include prior to cold startup of an engine, operating an e-compressor and opening a recirculation valve of a recirculation passage coupled across the e-compressor to flow compressed intake air from an outlet of the e-compressor through the recirculation passage to an inlet of the e-compressor and starting the engine upon a temperature at the outlet of the e-compressor reaching a threshold and continuing to operate the e-compressor while the engine is on. The heated intake air resulting from the flow of compressed intake air through the recirculation passage raises a temperature of combustion and a temperature of exhaust gas, which may decrease catalyst light-off time of the emissions device.

Abstract: Methods and systems are provided for an engine system configured with a wide range active compressor and high pressure EGR. In one example, a compressor may include an active casing treatment with a slideable sleeve may be adjusted to direct air flow through either a choke slot and surge slot to control compressor efficiency, thereby maintaining EGR flow. In another example, the compressor may comprise a variable inlet device to regulate air flow through the compressor, thereby adjusting compressor efficiency and also maintaining EGR flow.

Abstract: Methods, systems and apparatuses configured to isolate and/or damp vibration of refrigerant lines caused by, for example, the compressor are disclosed. A vibration control device can be configured hold a refrigerant line at a position that is away from the compressor. The vibration control device can help isolate the vibration, reducing or preventing the vibration from passing the vibration control device along the refrigerant line. A vibration-damping device can be configured to engage the refrigerant line so as to absorb/damp the vibration of the refrigerant line.
