Methods and systems are described for simplified creation of, connection to, and termination from an ad hoc wireless network. Graphical user interfaces are used to guide users though creation and joining ad hoc network. The option to share one user's Internet connection with the entire ad hoc network is also described. The ad hoc networks described can provide some managed services traditionally unavailable in ad hoc networks, such as IP address assignment and name resolution services. The ad hoc networks can be created with termination criteria, such that a computer's connection to the ad hoc network is automatically terminated and previous network configuration settings are restored when one or a combination of termination criteria are met.

The invention discloses a fermenting production method of cordycepin, and the method comprises the following steps of: transplanting activated bacterial strain cordyceps militaris into a fermentation tank filled with a fermentation culture medium, wherein the fermentation temperature is 25-28 DEG C, and the stirring rotation speed is 150-180rpm (revolutions per minute); feeding sodium hydroxide solution and hydrochloric acid to control the pH value of fermentation liquor at 5.5-6.0; and when a carbon source is completely consumed, reducing the stirring rotation speed to be 60-80 rpm, and replenishing a water solution containing glucose and adenosine into the fermentation tank by means of intermittent feeding, wherein the whole fermentation time is 200-280 hours. According to the fermenting production method, the pH value of the fermentation process is controlled, and the energy sources and the cordycepin precursor are timely replenished, so that the fermentation process can be kept under an optimum environment, and the fermenting production method is good for the growth of thallus, and good for the transplantation of metabolic flux, therefore, the cordycepin yield can be finally up to 10.0g / L, the production efficiency reaches 0.25g / L / d, and the method is simple in process, lower in environment pollution, convenient to operate, and high in cordycepin yield.

An environment difference detector includes an elastic surface wave element equipped with a substrate including a surface having an annular surface acoustic wave circulating path, a surface acoustic wave exciting / receiving unit exciting a surface acoustic wave along the circular path and receiving the circulated surface acoustic wave, and a sensitive film disposed on the circular path to change an elastic nature in accordance with a change in an adjacent environment, a speed / intensity measuring unit measuring a circulating speed and intensity of the surface acoustic wave from an electric signal generated by the unit when the unit receives the circulating surface acoustic wave, and an environment evaluation unit evaluating an environment adjacent to the sensitive film from at least one of the circulating speed and the intensity measured by the unit.

A calibration method of a stereo camera includes optionally setting a plurality of camera calibration parameters and a plurality of image rectification parameters of the stereo camera; executing an image capture step on at least one left eye pattern and at least one right eye pattern corresponding to each two-dimensional image of at least one two-dimensional image; generating a plurality of new camera calibration parameters according to a plurality of first images corresponding to all left eye patterns corresponding to the at least one two-dimensional image and a plurality of second images corresponding to all right eye patterns corresponding to the at least one two-dimensional image; and generating a plurality of new image rectification parameters of the stereo camera according to the plurality of new camera calibration parameters.

A document display device for displaying a document on a screen on the basis of document information, includes: a sensor for detecting an action made on the document display device; a document information storing means for holding the document information of documents to be displayed on the screen; and a correspondence information processing means for storing information of an action detected by the sensor in a state that a document is displayed on the screen in such a manner that it is correlated with document information of the document being displayed on the screen.
