Abstract:
An oil management controller for heating, ventilation, or air conditioning (HVAC) equipment. The controller includes a processing circuit. The processing circuit is configured to analyze operating data for the HVAC equipment using a machine learning model to predict a variable state or condition of oil used by the HVAC equipment. The processing circuit is configured to identify an oil deficiency based on the variable state or condition of the oil. The processing circuit is configured to automatically initiate a corrective action responsive to identifying the oil deficiency.
Abstract:
A refrigeration system for a mobile unit includes a refrigeration loop (32), an air duct (70), a sensor (34) and a shock absorption unit (36). The refrigeration loop includes a compressor, a condenser, a refrigerant regulator and an evaporator (64). 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 (22).
Abstract:
A method and system for lithography simulation is disclosed. The method and system specify a subject region of a lithography image with a CD marker, specify a threshold intensity over the lithography image, specify a gradient to a threshold value of the threshold intensity, and calculate a sensitivity or ratio of change of an image boundary of the lithography image to lithography process variation.
Abstract:
A high-frequency device (1) comprises a substrate sheet (10) of an elastic material (11) and a metal alloy (12) provided within and/or on the substrate sheet (10). The metal alloy (12) is liquid at temperatures below 1000°C. The metal alloy (12) is provided in an at least two-dimensional pattern (13). The metal alloy (12) is wetable in contact with a surface of the elastic material (11).

Abstract:
A system and method for improved electron beam writing that is capable of taking design intent, equipment capability and design requirements into consideration. The system and method determines an optimal writing pattern based, at least in part, on the received information.
Abstract:
A refrigerant charge controller for heating, ventilation, or air conditioning (HVAC) equipment, the controller comprising 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.
