Abstract: A pick and place nozzle performance analytics system streams production data from pick and place machines used in electronic assembly to a cloud platform as torrential data streams, and performs analytics on the production data to track, visualize, and predict performance of individual nozzles in terms of rejects or miss-picks. The analytics system generates a performance vector for each nozzle based on the collected production data, the performance vector tracking both the accumulated rejects and the percentage of rejects as respective dimensions of an x-y plane. The system monitors and analyzes the trajectory of this vector in the x-y plane to predict when performance degradation of the nozzle will reach a critical threshold. In response to predicting that nozzle performance degradation will exceed a threshold at a future time, the system can generate and deliver notifications to appropriate client devices.

Abstract: A system for real-time modeling includes a compressor designed to operate at a compressor speed, a compressor flow rate, and a compressor pressure ratio. The system also includes a memory designed to store an operating condition matrix that plots multiple compressor pressure ratios to each of a plurality of compressor speeds, and a related operating state matrix that plots multiple compressor flow rates to each of the plurality of compressor speeds. The system also includes a compressor controller to determine a target compressor speed and a target compressor pressure ratio, and to identify a target location in the operating condition matrix based on the target compressor speed and the target compressor pressure ratio. The compressor controller also determines a target compressor flow rate by interpolating values in the operating state matrix based on the target location, and to control the compressor based on the target compressor flow rate.

Abstract: A battery-less sensor device includes a sensor to sense an environmental condition, a power supply system, a memory, a communication device, and a processor. The power supply system includes energy harvesting devices to harvest energy from ambient energy sources for powering one or more components of the sensor device, and an energy storage device to store harvested energy. The memory stores sensor data associated with the environmental condition sensed by the sensor. The communication device transmits the sensor data to a BMS or remote device. The processor is configured to dynamically select one or more energy sources from the ambient energy sources to power one or more components of the sensor device according to an availability of energy from the ambient energy sources and/or an energy consumption requirement of the one or more components of the sensor device, and to control supply of power to the one or more components.

Abstract: An air conditioning management systems and an air conditioning management method based on demand response requirements. Particularly, their implementation involves stepdown and precooling optimization within the air conditioning management system and air conditioning management method. The technical achievement is that even when demand response power limitation is required, a user can still enjoy optimum cooling comfort within the power restriction limit.

Abstract: A numerical controller includes a data table on which data in which a size of a machining area and a setting value of a parameter, which is influenced by a size of a machining area, are associated with each other is registered. Further, the numerical controller estimates a size of a machining area based on a setting value of a parameter used for control of a machine tool. In the case where data corresponding to the estimated size of the machining area is registered on the data table, the numerical controller acquires a parameter setting value corresponding to the size of the machining area from the data table so as to set the parameter setting value.

Abstract: A numerical control device includes a tool-attitude vector tolerance input unit to accept a tolerance for correction amounts for tool-attitude vectors; a rotation-axis tolerance determining unit to determine, on the basis of tool attitudes calculated from rotation-axis angles before smoothing and of the tolerance for correction amounts for tool-attitude vectors, a tolerance for correction amounts for the rotation-axis angles; a rotation-axis angle smoothing unit to smooth the rotation-axis angles before smoothing so that change in the rotation-axis angle becomes smooth, thereby calculating rotation-axis angles after smoothing; and a rotation-axis angle determining unit to correct the rotation-axis angles after smoothing so as to fall within the tolerance for correction amounts for rotation-axis angles from the rotation-axis angles before smoothing.
