摘要:
A computing device, such as a smartphone, can replace the hardware of various instruments to overcome the cost issue in designing universal smart instruments. Distinguished from traditional instruments, a universal smart instrument takes the maximum advantage of the latest smart phone or mobile computing devices. The instrument control panel is realized on the smartphone by applying the interactive graphical representation of control and indicator elements common in real instruments such as knobs, buttons, dials, graphs and the like. Universal smart instruments unify heterogeneous measurement probes on the market into a single device that can be readily modified or expanded when new technologies need to be added to the existing system or current measurement requirement change. Universal smart instruments also make use of the internet to publish and share data, which was unable to be achieved in conventional propriety instruments.

Disclosed is a system and method for verifying the authenticity of goods for sale. The system includes an authenticity device on the product which determines a code using a two step authenticity algorithm which inputs time as a variable and outputs the code. The code may be displayed on the authenticity device. The smart device contacts the manufacturer via an application and a wide area network and provides identification information regarding the product. Based on the identification information, the manufacturer finds the copy of the authenticity algorithm stored at the manufacturer, runs the algorithm, and returns the code to the smart device.

Disclosed is an air filter and a method of manufacture for an air filter which is much more cost effective and provides greater operational effectiveness than state-of-the-art air filters. The air filter includes an outer metallic shell which may be used to attach the filter in line to ducting of a heating, ventilation, and air conditioning (HVAC) system. The filter may further include a filter unit made of activated carbon material. The filter unit may have one or more sections and may have a honeycomb cross section.

A method for data transmission based on a relay mobile communication system and an equipment thereof are provided by the present invention. The method includes: at least two transport planes are configured on the Un interface protocol stack of the relay equipment and the base station eNode B; the relay equipment and the eNode B transmit the data via at least two transport planes configured on the Un interface protocol stack. With the present invention, the throughput rate of the Un interface between the relay equipment and the eNode B in the relay mobile communication system is improved, and the time delay of the Un interface is reduced.

A press-down type composite putty knife which comprises a handle and a blade with a rear end of the blade inserted into a blade receiving slot at a front end of the handle; the rear end of the blade has a blade tang which is provided with a fixing notch; a latch is disposed at the front end of the handle inside its casing; latch springs are disposed under the latch for returning the latch to its original position; a pressing part is formed by an upper end of the latch which extends outwardly from an upper surface of the handle; a longitudinal slot in communication with the blade receiving slot is disposed at a lower portion of the latch; a fixing block corresponding to the fixing notch of the blade tang is disposed on a bottom surface of the longitudinal slot. The engagement between the latch and the fixing notch allows the handle and the blade of the present invention to be removably assembled, and therefore fulfill the object of replacing blades of different specifications on the same handle. Cost of use will be lower accordingly and carrying the knives becomes more convenient.

A cost effective multicolor sensor and related software achieves a spectral response that closely approximates an ideal photo response to measure optical measurement, for example photosynthetic photo flux density (PPFD). The spectra error of the sensor is smaller than that of the best commercially available sensor at a significantly reduced cost. The sensor may include an 8×2 array of filtered photodiodes and spectral photo sensors that are linearly combined with the appropriate mathematically determined coefficients to create a corrected spectral response curve that has a spectral error much smaller than the best commercial available sensors made by physical coating methods for the entire desired range.

摘要:
Negatively charged luminescent CdSe—ZnS quantum dots (QDs) were successfully incorporated into novel luminescent glyconanospheres averaging around 190 nm in diameter through electrostatic interactions with carboxymethyldextran (CM-dextran) and polylysine. The glyconanospheres preferably contain as well carboxyl-modified iron oxide nanocrystals. In addition to electrostatic attraction between the negatively charged dextran, the negatively charged CdSe—ZnS QDs (and negatively charged iron oxide nanocrystals, if present), and the positively charged polylysine, covalent amide bonds were introduced to cross link the QDs (and negatively charged iron oxide nanocrystals, if present) with the polysaccharide matrix to further stabilize the glyconanospheres. The dextran residues on the surface of the nanospheres show high affinity toward the glucose binding protein-Concanavalin A (Con A). As a result, these luminescent CdSe—ZnS QD incorporated glyconanospheres are a useful tool for studying carbohydrate-protein interactions that are critical steps in bacterial and viral infection.
