Abstract: A computer-implemented method including receiving a first signal from an input device of a hearing aid. The first signal may include a noise signal. The computer-implemented method may include low-pass filtering first periodic samples of the first signal, and the first periodic samples may be approximately periodic with respect to a period of the noise signal. The computer-implemented method may further include low-pass filtering second periodic samples of the first signal, and the second periodic samples may be approximately periodic with respect to the period of the noise signal. The second periodic samples may also be phase shifted relative to the first periodic samples. Hearing aid systems and apparatuses are also disclosed.

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 method for detecting a fuel leak in a compartment is provided. The compartment includes at least one inlet and an exhaust outlet that is coupled in flow communication with the compartment and in flow communication with a fan. The method includes determining a fan speed, measuring a fuel leak gas concentration value, determining a fuel leak gas concentration limit value within the compartment based on the determined fan speed, comparing the measured fuel leak gas concentration value with the determined fuel leak gas concentration limit value, and generating at least one of an alarm signal and a trip signal based on the comparison.

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: 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.

Abstract: In a system having an DSP, an ASIC and a memory, in which the ASIC generates a number of different competing interrupts for the DSP to service, the ASIC has an interrupt request control module which automatically provides the DSP with a vector pointing to the memory location of the interrupt service routine for the currently pending interrupt request having the highest priority of all pending requests. The DSP reads this vector and uses it to access the interrupt service routine in the memory. Reading of this vector causes the interrupt request to be de-asserted, which causes the next highest priority pending interrupt request to become the highest priority pending interrupt request. As a result, a new vector is presented for the next read by the DSP.

Abstract: A complex of a chelating agent is formed and labelled with technetium-99m. The chelating agent is either an ethylenediamine carboxylic acid or its salt having a phenolic group at each end of the molecule such as EDDHA and HBED or alternatively the phenolic amino carboxylic acid or its salt having a single phenolate group such as HBG or HBS. The complex is a stannous complex which when labelled with technetium-99m has a good balance of lipo-solubility and waater-solubility to permit hepato-biliary imaging. The radiopharmaceutical may be useful for assessing hepatobiliary function in animals including human beings. A particularly useful chelating agent is ethylene-bis-(.alpha.-imino-2-hydroxy-5-bromophenyl acetic acid).
