Abstract: There is provided a fan assembly comprising a motor-driven impeller for creating an airflow and a nozzle comprising a first air outlet. The nozzle defines a bore through which air from outside the fan assembly is drawn by any portion of the airflow that is emitted from the first outlet and which combines with the airflow emitted from the first air outlet to produce an amplified airflow. The fan assembly further comprises a second air outlet arranged such that any portion of the airflow that is emitted from the second air outlet does not draw air through the bore defined by the nozzle thereby producing a non-amplified airflow.

Abstract: A physically compact, wideband signal activity identification, demodulation and characterization, and direction finding device incorporates multiple and cascadable digital signal processing modules operating in asynchronous real time. The digital signal processing modules include a device for data buffering, a device for digital signal processing (DSP), and a device for high-speed data routing. The module device for data buffering is composed of, among other memory devices, a First In Tap Out (FITO) data buffer that may be accessed at any point for delay or faster than real time resynchronization by the DSP module device. The module device for digital signal processing function incorporates a general purpose digital processor for respective module calculation of overlapped hyperchannelization Fast Fourier Transforms (FFT).
