Abstract:
A USB connector for connecting with a USB female comprises metal legs, a connecting line, a substrate and a rotating shaft assembly. One end of the metal legs connects with one end of the connecting line. The metal legs are formed on a surface of the substrate. The connecting line is fixed to the surface of the substrate. The rotating shaft assembly is fixed to the surface of the substrate. The present invention also provides a USB device. According to the USB connector and the USB device of the present invention, the metal legs are formed on the surface of the substrate so as to ensure the connecting strength of the metal legs. Since the size of the USB connector depends mainly on the substrate and as long as the thickness meets a requirement of inserting the USB connector into the USB female, the thickness of the USB connector and further the thickness of the USB device are reduced without compromising the function of the USB connector. Compared with the conventional USB products, the thickness of the USB device according to the present invention is greatly reduced so that the USB device takes less space and easy to carry. It not only meets the people's requirement for exquisite and compact electronic products, but also improves the practicality and aesthetics of the USB device.
Abstract:
Photoinduced chemical vapor deposition was used to grow coatings on nanoparticles. Aerosolized nanoparticles were mixed with a vapor-phase coating reactant and introduced into a coating reactor, where the mixture was exposed to ultraviolet radiation. Tandem differential mobility analysis was used to determine coating thicknesses as a function of initial particle size.
Abstract:
A wireless terminal in a wireless communication field is provided, which not only includes a top layer body and a bottom layer body, but also includes at least one extending layer body to provide an extending function. The extending layer body is connected in a stacked way to the top layer body or the bottom layer body. The extending function of the wireless terminal is realized through the extending layer body, so that the wireless terminal has powerful capabilities of extending and combining the functions.

A method and apparatus for end-to-end retail store one-stop site configuration integrates multiple data sources, identifying key customers, forecasting merchandise demand. Site configuration is formulated as a mathematical optimization problem with both in-store and external data as input to the problem whose solution provides proper suggestions for retail store transformation.
Abstract:
An optocoupler system includes a buffer, isolation, and a detector. The system includes a current transfer ratio (CTR) with a temperature coefficient. The buffer includes a light source that generates light that passes through the isolation. A detector receives light that passes through the isolation and generates an output signal based on the received light. A current transfer ratio (CTR) temperature coefficient compensation mechanism is provided that generates a base signal with a temperature coefficient that compensates the temperature coefficient of the CTR.
Abstract:
The present invention relates to compositions for improving assay accuracy for plasma samples by decreasing or eliminating false results due to platelet interference. The compositions of the present invention comprise compositions that include a platelet interference reducing agent in an amount effective to decrease the platelet interference activity in the plasma sample, particularly platelet-rich plasma sample, to be analyzed. The most preferred platelet interference reducing agent of the present invention is 1-(1,3-Bis(hydroxymethyl-2,5-dioxoimidazolidin-4-iyl)-1,3-bis(hydroxymethyl) urea, also called “Diazolidinyl urea” or “DZU”.
Abstract:
In one embodiment, a current source circuit having a reference resistor produces first, second and third bias currents that vary with manufacturing variances of the current compensation resistor. An input amplification stage includes a transconductance stage biased by the first bias current, a first transimpedance amplifier (TIA) biased by the second bias current, and a first feedback resistor coupled between the first TIA's input and output. The input of the first TIA is coupled to an output of the transconductance stage. An output amplification stage is biased by the third bias current and has an input coupled to an output of the first TIA. A second feedback resistor is coupled between the output of the output amplification stage and the input of the transconductance stage. The reference resistor and first and second feedback resistors are formed using a common manufacturing process.
Abstract:
A method and a current sensor for measuring a current in a conductor. The sensor comprises a non-magnetic, flexible core member having a first end and a second end. A locking head having a channel therethrough is coupled to the first end of the core member. A first sensor conductor winding layer is mounted on the core member. Wherein the second end releasably engages the locking thread in the channel and adjustably configures the core member to surround the conductor as the second end is moved through the channel. In another embodiment the current sensor includes a locking tang within the channel and a plurality of sought tooth members on a portion of the core member and configured to selectively engage the locking tang as the second end of the core member is moved through the channel.
Abstract:
A method and system for determining regression functions from a computer data input using K-Harmonic Means (KHM) regression clustering (RC) and comprising the steps of: (1) selecting K regression functions ƒ1, . . . , ƒK; (2) associating an i-th data point from the dataset with a k-th regression function using a soft membership function; (3) providing a weighting to each data point using a weighting function to determine the data point's participation in calculating a residue error; (4) calculating the residue error between the weighted i-th data point and its associated regression function; and, (5) iterating to minimize the total residue error. Such can be applied in data mining, economics prediction tools, marketing campaigns, device calibrations, visual image segmentation, and other complex distributions of real-world data.
