A sensor system that detects a current representative of a compound in a liquid mixture features a multi or three electrode strip adapted for releasable attachment to signal readout circuitry. The strip comprises an elongated support which is preferably flat adapted for releasable attachment to the readout circuitry; a first conductor and a second and a third conductor each extend along the support and comprise means for connection to the circuitry. The circuit is formed with single-walled or multi walled nanotubes conductive traces and may be formed from multiple layers or dispersions containing, carbon nanotubes, carbon nanotubes/antimony tin oxide, carbon nanotubes/platinum, or carbon nanotubes/silver or carbon nanotubes/silver-cloride. An active electrode formed from a separate conductive carbon nanotubes layer or suitable dispersion, positioned to contact the liquid mixture and the first conductor, comprises a deposit of an enzyme capable of catalyzing a reaction involving the compound and preferably an electron mediator, capable of transferring electrons between the enzyme-catalyzed reaction and the first conductor. A reference electrode also formed from a conductive carbon nanotube layer or suitable dispersion is positioned to contact the mixture and the second conductor. The system includes circuitry adapted to provide an electrical signal representative of the current which is formed from printing conductive inks made with nano size particles such as conductive carbon or carbon/platinum or carbon/silver, or carbon nanotubes/antimony tin oxide to form a conductive carbon nanotube layers. The multiple-electrode strip is manufactured, by then applying the enzyme and preferably the mediator onto the electrode. Alternatively the electrode can have a carbon nanotubes/antimony tin oxide, carbon nanotubes/platinum, or carbon nanotubes/silver or carbon nanotubes/silver-cloride surface and or a conductive carbon or silver ink surface connecting leg. The carbon nanotube solution is first coated and patterned into electro shapes and the conductive carbon nanotubes, carbon or silver ink can be attached by printing the ink to interface with the carbon nanotube electro surface. A platinum electrode test strip is also disclosed that is formed from either nano platinum distributed in the carbon nanotube layer or by application or incorporation of platinum to the carbon nanotube conductive ink.

High-temperature direct-injection disperse ink as well as preparation method and application thereof

The invention discloses high-temperature direct-injection disperse ink as well as a preparation method and an application thereof. The ink is prepared from the following raw materials in parts by weight: 15-60 parts of high-temperature disperse dye, 0.3-20 parts of dispersant, 30-60 parts of organic solvent, 10-50 parts of water, 0.5-10 parts of surfactant, 0.05-0.2 part of preservative and 0.05-0.2 part of defoamer. The preparation method comprises the steps of evenly mixing the high-temperature disperse dye, the dispersant, the organic solvent and water together, adding zirconium beads for grinding and dispersing, and then adding the rest organic solvent, water, the surfactant, the preservative and the defoamer to the mixture, mixing evenly, and filtering to obtain the filtrate. The ink is applied to a novel industrial digital textile printing machine and in particular to a textile printing machine with a precision work 508GS nozzle; the ink can be directly injected for printing by using the printing machine, and therefore, the utilization rate of the ink is increased, the cost is reduced and the environmental pollution is reduced; the ink can be dyed quickly at high temperature without transfer printing, and thus has the advantages of short dyeing time, firm dyeing and the like.

Video encoding and transmitting method based on TD-LTE (time division long term evolution) channel detection

The invention discloses a video encoding and transmitting method based on TD-LTE (time division long term evolution) channel detection. Adaptive video encoding and transmitting technology based on channel detection is used for TD-LTE system video services, a video rate is adaptively adjusted along with the change of channel conditions by adding a TD-LTE channel real-time detection module and a video encoding coefficient estimation module at a video source end, the real-time detection module obtains parameters of a TD-LTE system such as channel capacity, channel error rate and received signal strength at the video source end, so that video encoding coefficients such as resolution, a quantization coefficient QP and frame rate are determined, and the video encoding rate is adaptively adjusted based on channel detection. The video encoding and transmitting method has the advantages that the video source end can adaptively adjust encoding parameters and code stream rate to meet video data transmitting requirements under the condition of dynamically changing channels, video transmitting real-time performance and video transmitting continuity can be ensured, and the method solves the problems of high error rate, long delay, low channel use rate and the like when the video data are transmitted.
