A method and system for releasing active ingredients into the surrounding atmosphere is disclosed. In one embodiment, the dispersion rate of the active ingredient through the membrane is passively regulated by adjusting the porosity of the membrane. In another embodiment, materials with microfluidic channels of various diameters are interposed together so that the configuration of the channels approximates a venturi, thereby improving the flow of the solution through the microfluidic channels. In another embodiment, heat is applied to the top membrane layer to further accelerate the rate at which fluid is dissipated through the membrane structure. Devices incorporating membranes with the disclosed properties are also presented.

A digital computer system has an error correction code (ECC) syndrome encoder for generating initial ECC syndromes from digital words input to the system which are received together with their corresponding ECC syndromes, in the system receiving circuitry. The system has an ECC syndrome re-encoder for generating second ECC syndromes from the digital words as they are removed from the receiving circuitry. A comparison circuit then compares the originally encoded syndrome with the re-encoded syndrome as it is being generated, to detect whether there is a difference and therefore an error in the digital word or an error in the syndrome. The comparison circuit is integrated into and is a part of the ECC re-encoder.

An integrated circuit is formed in a semiconductor chip and connected to at least a first source of voltage and at least a second source of voltage, negative with respect to the first source of voltage. A number of integrated circuit components are activated by the first and second sources of voltage and are interconnected to provide desired functions. An integrated circuit capacitive element in the form of the gate capacitance of a field effect transistor and in the form of a reversed biased diode is connected between the first and second sources of voltage to decouple integrated circuit inherent inductance in series with the first and second sources of voltage.
