Abstract: A heat pump system provides at least six modes of heating, cooling, and/or domestic water heating operation, where domestic water heating may occur concurrently with heating or cooling a space in a structure. The heat pump system comprises a desuperheater positioned downstream of the compressor and operable as a desuperheater, a condenser or an evaporator, a source heat exchanger operable as either a condenser or an evaporator, a load heat exchanger operable as either a condenser or an evaporator, a reversing valve positioned downstream of the desuperheater heat exchanger and configured to alternately direct refrigerant flow from the desuperheater heat exchanger to one of the load heat exchanger and the source heat exchanger and to alternately return refrigerant flow from the other of the load heat exchanger and the source heat exchanger to the compressor, and an expansion valve positioned between the load heat exchanger and the source heat exchanger.

Abstract: A vehicle wheel alignment system has a plurality of cameras, each camera for viewing a respective target disposed at a respective wheel of the vehicle and capturing image data of the target as the wheel and target are continuously rotated a number of degrees of rotation without a pause. The image data is used to calculate a minimum number of poses of the target of at least one pose for every five degrees of rotation as the wheel and target are continuously rotated the number of degrees of rotation without a pause. At least one of the cameras comprises a data processor for performing the steps of preprocessing the image data, and calculating an alignment parameter for the vehicle based on the preprocessed image data.

Abstract: An air conditioning system can be toggled between a heating mode, in which heat is withdrawn from a source (e.g., a geothermal source) and deposited into a conditioned space (e.g., a building), and a cooling mode, in which heat is withdrawn from the conditioned space and deposited into the source. The air conditioning system uses a combination of efficiency-enhancing technologies, including injection of superheated vapor into the system's compressor from an economizer circuit, adjustable compressor speed, the use of one or coaxial heat exchangers and the use of electronic expansion valves that are continuously adjustable from a fully closed to various open positions. A controller may be used to control the system for optimal performance in both the heating and cooling modes, such as by disabling the economizer circuit and vapor injection when the system is in the cooling mode.

Abstract: An air conditioning system can be toggled between a heating mode, in which heat is withdrawn from a source (e.g., a geothermal source) and deposited into a conditioned space (e.g., a building), and a cooling mode, in which heat is withdrawn from the conditioned space and deposited into the source. The air conditioning system uses a combination of efficiency-enhancing technologies, including injection of superheated vapor into the system's compressor from an economizer circuit, adjustable compressor speed, the use of one or coaxial heat exchangers and the use of electronic expansion valves that are continuously adjustable from a fully closed to various open positions. A controller may be used to control the system for optimal performance in both the heating and cooling modes, such as by disabling the economizer circuit and vapor injection when the system is in the cooling mode.

Abstract: A geothermal heat pump system which may be installed in a building and operated as an air source heat pump system using an exterior heat exchanger as a heat source or heat source/sink, but which includes geothermal components including a geothermal heat exchanger. The geothermal heat exchanger may be isolated in initial operation of the system for heating and cooling but may be connected to a geothermal heat source/sink following initial installation of the heat pump system for use in heating and cooling as a heat source and a heat source/sink, respectively. In this manner, the heat pump system may be initially operated as a standard air source heat pump and optionally later converted into a geothermal heat pump system.

Abstract: Systems, methods, and devices for creating a test performance monitoring and reporting system that is adaptive for use with different types of mobile devices are disclosed. The test performance monitoring and reporting system adapts itself to be interoperable with different models of mobile device by combining sequences of deterministic logic blocks with device-specific asset libraries. Logic blocks can be added to or removed from the sequence. Logic blocks implement different operations of mobile devices, including using assets, launching applications, and replaying sequences of command interface interactions recorded from test users. The asset library contains assets corresponding to mobile device elements that can be manipulated by users. These assets are device-specific, and a test script can be adapted to fit a particular mobile device model by replacing the existing assets in the script with assets from the asset library of the particular mobile device.
