Abstract: In a stream computing application, data may be transmitted between operators using tuples. However, the receiving operator may not evaluate these tuples as they arrive but instead wait to evaluate a group of tuples—i.e., a window. A window is typically triggered when a buffer associated with the receiving operator reaches a maximum window size or when a predetermined time period has expired. Additionally, a window may be triggered by a monitoring a tuple rate—i.e., the rate at which the operator receives the tuples. If the tuple rate exceeds or falls below a threshold, a window may be triggered. Further, the number of exceptions, or the rate at which an operator throws exceptions, may be monitored. If either of these parameters satisfies a threshold, a window may be triggered, thereby instructing an operator to evaluate the tuples contained within the window.

Abstract: Improved capacitive sensor operation is achieved with improved discrimination between environmental drift and apparent drift attributable to human proximity to the sensor. A proximity algorithm detects conditions interpreted as indicating a user is close to, but not touching, a sensor. When such proximity is detected, ambient value calibration is halted, thereby avoiding treating the human's proximity as environmental drift requiring compensation and preventing miscalculation of calibration. The proximity algorithm employs two moving-average filters (implemented in hardware or software) to monitor the CDC output values over time and to make appropriate adjustments to a signal representing the ambient, while distinguishing environmental drift from proximity-induced pseudo-drift.
