Abstract: The invention provides, in some respects, a digital data processing method of identifying a person of interest in a video stream. The method, which executes on a digital data processing system including one or more digital data processing devices in communications coupling with one another, includes detecting using a detector and without using a facial recognizer one or more faces in a video stream. It further includes using a tracker to associate, without using a facial recognizer, one or more of the detected faces with a same apparent individual, and scoring, again, without using a facial recognizer, each of the detected faces that are associated with the same apparent individual. The method further includes applying selected ones of the scored detected faces of the same apparent individual to a facial recognizer to identify a person of interest, where selection is based on scores of the detected faces.

Abstract: An electrical connector includes a hook-up pin mounted on one lateral side of the electrical connector. The hook-up pin includes a pin body, soldering sections respectively formed on two sides of an end of the pin body, an elastic pressing section formed on an end of the pin body that is adjacent to the soldering sections, and a hook section formed on an end of the elastic pressing section that is distant from the soldering sections. The soldering sections are arranged to clamp and be soldered to opposite sides of the circuit substrate. In inserting male and female parts of the present invention to each other, the soldering sections clamp on and are soldered to two sides of the circuit substrate so as to be resistant to the force of insertion and removal and be protected against damage. Further, the hook section helps prevent undesired detachment.

Abstract: An integrated wind turbine acoustic-noise and shadow-flicker recognition system, comprising monitors located at nearby locations and base-units installed in each wind turbine, is described. The system comprehensively addresses neighbors' concerns with potential sound- and flicker-based nuisance emissions. Each monitor includes a computer processor; a microphone and light-monitor; a two-way communication system for interaction with the base-unit; and a set of indicator-lights. Each base-unit includes a computer processor; a two-way communication system for interacting with local monitors; plus a display, data-ports, and programming interfaces. Collectively, computer processors in the monitors and base-units jointly assess acoustic, optical, and turbine operating data to signal a mitigation event. The methods used to determine a mitigation event are based on a unique signature-recognition methodology that relies on analysis of data received at both the turbine and at the monitored location.
