Motion cancellation of optical input signals for physiological pulse measurement

A pulse rate sensor that includes an accelerometer for measuring periodic motion and a piezo sensor for detecting erratic motion is capable of more accurately determining pulse rate by accounting for these types of motion. The pulse rate sensor in accordance with the present invention diminishes pulse rate signal degradation due to erratic motion through a combination of algorithms that control signal boosting, waveform refinement and signal noise suppression.

Method to form a pattern of functional material on a substrate

The invention provides a method to form a pattern of a functional material on a substrate. The method uses an elastomeric stamp having a relief structure with a raised surface and having a modulus of elasticity of at least 10 MegaPascal. A liquid composition of the functional material and a liquid is applied to the relief structure and the liquid is removed to form a film on the raised surface. The elastomeric stamp transfers the functional material from the raised surface to the substrate to form a pattern of the functional material on the substrate. The method is suitable for the fabrication of microcircuitry for electronic devices and components.

Production process of dipping agent bitumen

The invention relates to a method for manufacturing impregnant bitumen. The method comprises the following steps: aliphatic hydrocarbon solvent and aromatic hydrocarbon solvent are selected to make mixed solvent; mid-temperature coal pitch or coal tar maltha and the mixed solvent are fed in at least three stages of mixers in a certain proportion, and then are fed in an extracting tower for separation after fully mixing; light phase bitumen and heavy phase bitumen with less quinoline insoluble content are extracted for separation inside the extracting tower; and the impregnant bitumen is obtained through the steam stripping of the light phase bitumen inside a stripping tower. The method makes use of equipment with simple structure, and bitumen blockage is not easy to occur; moreover, the method can realize continuous industrial production of high-quality impregnant bitumen, and reduces cost.

Clearing device for smoke pollutants of glass kiln and clearing method thereof

The invention relates to smoke treatment, in particular provides a clearing device for smoke pollutants of a glass kiln and a clearing method thereof. The clearing device is suitable for the glass kiln with high smoke temperature, smaller smoke amount, high clearing efficiency, stable system operation, simple structure and small floor area and is provided with an afterheat recovery boiler, a reaction tower, a bag dust collector, a circulating fluidization flume, a clean smoke recirculating flue, an absorbent bin and a feeding air flume which are sequentially connected. The clearing method comprises the following steps: smoke emitted by the glass kiln enters the afterheat recovery boiler; original smoke emitted by the afterheat recovery boiler enters a high-temperature reaction region of the reaction tower for premixing treatment with an absorbent, is accelerated by a Venturi accelerating region before entering a circulating fluidization reaction region and is cooled and purified before entering the bag dust collector; the purified smoke emitted from the reaction tower firstly enters the bag dust collector to remove particles and is emitted to a chimney by a draft fan in a purification chamber; and reaction dust emitted by the reaction tower is collected by the bag dust collector and is returned to the high-temperature reaction region.

Technique of pre-expanding treating cabo

A tobacco stalk pre-expending processing technics is provided, which is characterized in that: the technics comprises the following procedures: washing, storing, expanding in liquid and marinating with interface the tobacco stalk, expanding the stalk strips, moisture regaining and feeding, storing, pressing sticks and drying for shaping. The technics method of the invention changes the expanding of cut rolled stem into expanding the tobacco stick by using marinating with high temperature and low pressure and then expanding with high temperature and reduced preddure, thus sufficiently eliminating the bad flatus in the tobacco stick as the flatus of the wood or the corrupt straws; the tobacco stick after expanded has increased cells and remarkably enhanced ratio surface, thus the material liquid can filter into the tobacco sticks sufficiently to becoming a natural filling material and adaptation carrier for adjusting the cigarette fragrance and style; the cigarette stick after expanded is large in volume, which, after pressed, is easy being cut into silkiness (similar as the physical behavior of tobacco shred); after dried and shaped normally, the cut rolled stem can crisp naturally, thus increasing the filling capacity. The cut rolled stem processed by the technics method of the invention is basically similar with tobacco shred in color and shape and the alloying evenness of the tobacco shred is increased; besides, the tobacco shred has no bad aftertaste when smoking, but has strong filling capacity and enhanced internal quality.
