摘要： A compound resistor is used to compensate for trimming induced shift in temperature coefficient of resistance of a trimmable resistor. The compound resistor is composed of a first and second portion, at least one of the two portions being thermally trimmable, and the parameters for the first and second portion are selected such that the trimming induced shift can be minimized on an overall resistance and temperature coefficient of resistance of the compound resistors by trimming the trimmable resistor.

摘要： There are described various methods and circuits for trimming the parameter value of a thermally mutable electrical component in two directions. A sequence of heat pulses is selected as a function of thermal history using an adaptive trimminig algorithm, where parameters of the sequence of heat pulses are based on a resulting impact of previous heating pulses. Direction of trimming, trimming increment, and remaining trimming distance can all be used to determine the parameters of succeding heat pulses, wherein the parameters of the pulses can be, for the example, amplitude, duration, and time interval between pulses.

摘要： There is described a method for producing a packaged integrated circuit. The method comprises a first step of building an integrated circuit having a micro-structure suspended above a micro-cavity, and having a heating element on the micro-structure capable of heating itself and its immediate surroundings. A layer of protective material is then deposited on said micro-structure such that at least a top surface of the micro-structure and an opening of the micro-cavity is covered, wherein the protective material is in a solid state at room temperature and can protect the micro-structure during silicon wafer dicing procedures and subsequent packaging. The integrated circuit is packaged and an electric current is passed through the heating element such that a portion of the protective material is removed and an unobstructed volume is provided above and below the micro-structure.

摘要： This invention addresses a fundamental weakness in currently common microphones, and their applications in feedback for audio speaker systems. This limitation stems from the fundamental difficulties of typical membrane-type microphones in the frequency range 1-100Hz. The self-noise of membrane-type microphones increases in this range approximately as 1/f, and membrane-type microphones are sensitive to parasitic inertial vibrations, which are usually very important in this frequency range. The removal of these limitations enables the use of such a sensor (APV sensor) for effective feedback in audio speakers, dramatically improving performance in the low-frequency range of 10-100Hz. Without feedback, typical audio speakers suffer severe attenuation and/or distortion in this range.

摘要： A gas flow receiver has a non-symmetrical-flow-inducing diaphragm mounted in a flow tube and causes non-symmetrical flow in the flow tube with an accentuated higher pressure near an upstream orifice than would be sensed in a corresponding cross-section of the flow tube and an accentuated lower pressure near a downstream orifice. A gas flowmeter using thermoanemometer-type transducers receiving gas flow from the upstream orifice is made immune to vibration or acceleration, for example, by arranging a pair of the transducers parallel to one another with the gas flow passing serially through them, but in opposite directions. The resulting transducer signals processed to cancel the effect of the vibration or acceleration. The transducer output is amplified by a noisy amplifier which injects a secondary signal prior to digital conversion using an ADC. The digital signal is averaged over a sampling period to obtain a sample having a level of precision greater than a minimum quantization value of the ADC. The sampling period is varied as a function of the transducer's analog signal amplitude, such that the sampling period is longer for lower amplitude values and is shorter for higher amplitude values. The sampling period variation provides signal filtering. Since the flowmeter has a non-linear response, a calibrated output signal representing flow is obtained by recording samples under a number of calibrated flows and obtaining an analytical solution for the non-linear function, using the analytical solution to obtain calibrated values for all sample values, and, in operation, looking up a calibrated value corresponding to a sample value.
