Abstract: A ceiling-mounted sensing unit includes (i) one or more air temperature sensors; (ii) an infrared sensor having a field of view oriented towards a floor of the room; and (iii) a microcontroller receiving readings from both the air temperature sensors and the infrared sensor, the microcontroller providing an estimated temperature at a predetermined distance above the floor of the room based on a model of the room. The model may be based on a double-exponential smoothing function obtained by matching a Kalman filter model. Alternately, the model may be itself a Kalman filter model or a machine learning trained linear model obtained using a linear regression technique, such as L2 regularization. The Kalman filter model uses a state vector that includes both the estimated temperature and a rate of change in the estimated change in temperature. The machine-trained model may be verified using a k-fold cross-validation technique.

Abstract: A ball grid array device includes a monitoring circuit of inactive solder joints and a processor such as a field programmable gate array (FPGA) or other processor capable of determining the open or closed status of the monitoring circuit. The monitoring circuit traverses one or more of the solder joints between components being joined, such as a printed circuit board and an integrated circuit device. In certain embodiments, the inactive solder joints may be located within regions of the ball grid array that are predisposed to failure, such as at the periphery or corners of the printed circuit board, or proximate to regions that experience a broad range of operating temperatures. The failure of a solder joint within the monitoring circuit can be used to schedule maintenance of the ball grid array device prior to failure of an active solder joint.
