Abstract: A new subband feedback cancellation scheme is proposed, capable of providing additional stable gain without introducing audible artifacts. The subband feedback cancellation scheme employs a cascade of two narrow-band filters Ai(Z) and Bi(Z) along with a fixed delay, instead of a single filter Wi(Z) and a delay to represent the feedback path in each subband. The first filter, Ai(Z), is called the training filter, and models the static portion of the feedback path in ith subband, including microphone, receiver, ear canal resonance, and other relatively static parameters. The training filter can be implemented as a FIR filter or as an IIR filter. The second filter, BI(Z), is called a tracking filter and is typically implemented as a FIR filter with fewer taps than the training filter. This second filter tracks the variations of the feedback path in the ith subband caused by jaw movement or objects close to the ears of the user.

Abstract: A method to ventilate a rotary machine housed in a compartment having a ventilation air inlet and air exhaust, a variable speed ventilation fan and a temperature sensor, wherein the method includes: sensing a temperature level of the rotary machine; applying the sensed machine temperature level to a controller for the fan; drawing ventilation flow through the compartment and over the machine; determining whether the sensed machine temperature level is above a desired temperature level of the rotary machine, wherein the desired temperature level is determined by the controller, and the controller setting an operational condition of the fan to increase the ventilation flow through the compartment if the sensed machine temperature level is above the desired temperature level.

Abstract: A hinged flexible plastic shell in which barbed fishing lures and fish-hooks in general may be kept to avoid injury connects to a fishing rod merely by an operator's closing of its lid upon the rod by pop-open and pop-shut manipulation of certain nodes atop the shell's lid. To close, he or she depresses a pop-shut node against an enclosure ridge on the underlying storage portion. To open, either of the pop-open nodes may be depressed against notch shoulders to cause the lid to flex outward to position it for co-engagement with the lower portion.

Abstract: An apparatus and method for transferring data between a host system and a communication network via a communication module wherein the communication module presents a UART-like interface to the host system. The communication module is comprised of an emulated UART module, a digital signal processor (DSP), and a DSP memory. The emulated UART provides a compatible UART-like front end for interlacing directly with a host system and additionally performs direct memory access-like (DMA) functions enabling the direct transfer of transmit data between the host system and DSP memory that is directly accessible by the DSP for modulation and/or other processing such as data compression. The emulated UART module additionally provides performance features such as adjustable buffering quantity thresholds for triggering interrupts to either the host system or DSP, and pacing features that provide the host system with the appearance and performance of a serialized UART.
