Abstract: An installable HVAC system is used for a vehicle. The HVAC system may comprise: a housing; a compressor; a motor operatively coupled to the compressor; a condenser in fluid communication with the compressor; and a power management controller configured to run the motor with power from a given power source. The compressor, the motor, the condenser, and the power management controller are located within the housing. The housing is configured to attach to an existing HVAC system of the vehicle.

Abstract: An HVAC system to be installed in a vehicle may comprise at least one power source; a plurality of heating devices; and a component controller. The component controller may be configured to operate a selected portion of the plurality of heating devices based on user preferences stored in the component controller, available power from the at least one power source, and a desired set point temperature.

Abstract: The disclosed power system may comprise first and second batteries; an electrical power generator; an electrical load powered by at least one of the first battery, the second battery or the electrical power generator; a converter; and a battery management controller. The converter is connected to both the first and second batteries and configured to operate in a neutral mode, a first battery charging mode, or a second battery charging mode. The converter is configured to create a voltage difference between the first and second batteries in the charging modes. The battery management controller is configured to monitor the voltage of the first battery and the voltage of the second battery and/or to monitor current flow to and from the first and second batteries. The controller controls operation of the converter to operate in the neutral mode, the first battery charging mode or the second battery charging mode.

Abstract: An HVAC diverter valve including a diverter valve body. The diverter valve body includes an inlet, a first outlet, and a second outlet. The HVAC diverter valve further includes a flow constrictor assembly, and at least one motor adapted to adjust the flow constrictor assembly to divert air entering the inlet to the first and second outlet and maintain a substantially constant backpressure in front of the valve during air diversion.

Abstract: An HVAC system including a first diverter valve configured to divert, in varying amounts, an airflow entering the valve out two different outlets, in a manner that does not create a substantial increase in backpressure due to the diversion or otherwise substantially restrict the general flow of air in the HVAC system. The system further includes a first sensor assembly configured to sense a first environmental condition that includes at least one of temperature and a phenomenon indicative of the makeup of room air, a control unit, and a user interface unit, wherein the control unit is in communication with the diverter valve and the first sensor assembly.

Abstract: An oil replacement system for a vehicle can include oil quality sensor that directly determines the quality of the oil in the vehicle and sends an oil quality signal to a control system. Such an oil quality sensor can make a direct measurement of the quality of the oil in an engine oil system, thus permitting the oil replacement system to accurately determine the quality of oil in an engine oil system and whether the oil needs to be replaced.

Abstract: The disclosed energy storage and gyroscopic stabilizing system may be used in a marine vessel so as to supply energy, retrieve energy, and dampen the roll motion of the marine vessel. The system may comprise a rotating member configured to be rotatable and to dampen a roll motion of the marine vessel and a motor/generator in communication with the rotating member and configured to supply energy to and retrieve energy from the rotating member.

Abstract: An air conditioning system including a variable speed compressor configured to operator at faster and slower speeds. The system includes an evaporator and a thermal expansion valve for regulating the flow of a refrigerant from the compressor to the evaporator. The system includes a flow restricting device in a flow path from the thermal expansion valve to the evaporator thereby increasing the efficiency of the system when the compressor is operating at slower speeds.

Abstract: A self-contained environmental control and power system (ECAPS) unit including an HVAC system with at least one variable-speed compressor driven by a DC motor, wherein the HVAC system is adapted to condition air and output the conditioned air and a variable-speed diesel engine connected to a generator. The generator is configured to vary in speed so as to output AC power at a variable frequency. The unit includes a rectification assembly which transforms the AC power from the generator and/or external AC power to DC power, and an inverter assembly which transforms the DC power to an export AC power. The ECAPS unit directs the DC power to the DC motor to drive the variable speed compressor and varies, in a controlled manner, at least one parameter of the outputted conditioned air from the HVAC system.
