A refrigerant charge controller for heating, ventilation, or air conditioning (HVAC) equipment includes a processing circuit configured to analyze usage data for the HVAC equipment using a machine learning model to estimate an amount of refrigerant used by the HVAC equipment, identify a refrigerant deficiency based on the amount of refrigerant, and initiate a corrective action in response to identifying the refrigerant deficiency.

An automatic work order generation system for model predictive maintenance (MPM) of building equipment including an MPM system including an equipment controller to operate the building equipment to affect an environmental condition of a building. The MPM system can perform a predictive optimization to determine a service time at which to service the building equipment. The automatic work order generation system includes an equipment service scheduler that can determine whether any service providers are available to perform equipment service within a predetermined time range of the service time. In response to determining that service providers are available to perform the equipment service, the equipment service scheduler can select a service provider and an appointment time based on one or more service provider attributes. The equipment service scheduler can generate a service work order and transmit the service work order to the service provider to schedule a service appointment.

Model predictive maintenance system with automatic service work order generation

The present invention provides a magnetic resonance imaging system for imaging a subject by a multi-shot imaging. The magnetic resonance imaging system comprises an acquiring unit for acquiring MR raw data corresponding to a plurality of shots; an imaging unit for generating a plurality of folded images from the MR raw data, wherein each of the plurality of folded images is generated from a subset of the MR raw data; a deriving unit for deriving magnitude of each pixel of each folded image; a detecting unit for detecting a motion of the subject during the multi-shot imaging based on similarity measurements of any two folded images of the plurality of folded images, wherein the detecting unit further comprises a first deriving unit configured to derive the measured similarities; and a reconstructing unit for reconstructing a MR image of the subject based on MR raw data obtained according to a detection result of the detecting unit. Since the partially acquired MR raw data is used for motion detection directly, it would be more rapid and stable.

Mutli-shot magnetic resonance imaging system and method

A method and apparatus for magnetic resonance (MR) diffusion tensor imaging (DTI) with minimizes artifacts caused by motion-induced changes of the diffusion encoding. An object () is subject to at least one shot of a multi-echo imaging sequence to generate a train of echo signals. The multi-echo imaging sequence includes diffusion gradients, acquiring the echo signals for different diffusion gradients, detecting motion of the object () during acquisition of the echo signals, determining a plurality of motional states of the object () based on the detected motion, wherein the object () is stationary in each detected motional state, determining directions of the diffusion gradients relative to a reference frame of the object () for detected motional states of the object (), respectively, and deriving diffusion coefficients from the acquired echo signals for the determined relative directions of the diffusion gradients.

DTI with correction of motion-induced diffusion gradient inconsistency

A refrigeration system for a mobile unit includes a refrigeration loop (), an air duct (), a sensor () and a shock absorption unit (). The refrigeration loop includes a compressor, a condenser, a refrigerant regulator and an evaporator (). The air duct directs air from an air inlet to the evaporator, which air duct is defined by first and second panels. The sensor is disposed in the air duct. The shock absorption unit mounts the sensor to and provides a limited thermal conduction path between the sensor and the first panel ().
