Method and apparatus for geolocation of a network user

A database correlating the geographic locations of users of a network to the network address through which the users access the network is maintained and used to infer the geographic location of other users of the network that access the website through the same IP addresses. An Internet website operator may generate such a database from home or business address information self-reported by users of the website. If a plurality of users that access a website through the same IP address have self-reported information as to their geographic location to a website operator, that information collectively provides information as to the likely geographic location and the geographic diversity of other users that access the network through that IP address. Accordingly, such information is used to infer the extent to which a given IP address is likely to correlate to any particular geographic area and the particular area. Additionally, a website operator that has information indicative of the veracity of the self-reported location information may use that information to rate the likelihood that the self-reported location information for a given user is truthful and then use that rating to provide an even more accurate rating of the likelihood that an inferred location of a user is in a given location.

Method and device for computer visual inspection classification of quality of fresh corn ears

The invention discloses a method and a device for computer visual inspection classification of the quality of fresh corn ears, which aim to solve the problem that an artificial classification method makes the accuracy and the reproducibility of classification generated adverse effects. The method comprises the following steps of: 1, under a certain illumination condition, acquiring images of the fresh corn ears passing through a place right below a camera by an image acquisition device, and transmitting the images to a main control computer; 2, according to the acquired images of the fresh corn ears, performing image analysis by the main control computer through intelligent analysis software through the steps of: partitioning backgrounds of the images of the fresh corn ears by adopting an iteration-replacement method, and then extracting characteristics as quality indexes of the fresh corn ears on the basis of the images obtained after the background partitioning of the images of the fresh corn ears; and 3, on the basis of the quality indexes, which are acquired through the image analysis, of the fresh corn ears, and according to a grading standard that the fresh corn ears are classified into three grades, performing grade estimation on the fresh corn ears by using a fuzzy neural network. The invention also provides a detection device for implementing the method.

Fluid control measuring and controlling device

Systems and methods for measuring and controlling fluid flow comprises an orifice plate defining a variable opening, wherein the orifice plate includes an outer assembly comprising a central opening and an inner assembly extending through the central opening. Another embodiment comprises a plurality of blades disposed parallel to each other, wherein the blades are pivotable along its longitudinal axis and include at least one low-flow blade or partial blade and a plurality of high-flow blades The flow device regulates high and very low volumes of fluid with precision, inexpensively, with superior acoustics, reduced energy, a simpler design, and prevents building infiltration. The high turndown device permits use at lower velocities, thereby reducing noise generation and eliminating need for sound-attenuating liners. The high rangeability device combines several part numbers into fewer parts, thereby streamlining product portfolios. Cost benefits associated with the flow device allow equipment to be scaled back 100:1 rather than legacy 4:1, providing energy savings, fewer product variations, simple and more robust applications. The device meets new and old building fresh air, comfort and energy codes. The flow device can be engineered, selected, and sized without sophisticated software programs.
