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 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.

Abstract: A simplified algorithm for digital signal interpolation and a novel architecture to implement the algorithm in an integrated circuit (“IC”) with significant space constraints are presented. According to embodiments of the present invention, the interpolator is divided into two parts. The first part of the interpolator increases the sample rate by a factor of two and smoothes the signal using a half-band Infinite Impulse Response (“IIR”) filter. The second part of the interpolator increases the sample rate of the signal by a factor of thirty-two using a zero-order-hold (“ZOH”) circuit. In one embodiment, the half-band IIR filter is implemented using an all-pass lattice structure to minimize quantization effects. The lattice coefficients are chosen such that the structure can achieve all filter design requirements, yet is capable of being implemented with a small number of shifters and adders, and no multipliers.
