Method and apparatus for making secure electronic payments

InactiveUS20030061170A1Eliminates merchant concerns regarding the token monetary balanceEasy to acceptFinanceVisual presentationReceiptAuthorization
In accordance with the present invention, a consumer communicates a request for purchase of goods and services to a merchant, the goods and / or services being selected from these listed together with their price quotes on the merchant's computer or website connected to a network, such as the Internet. The merchant then communicates a request for a token and an update key to the clearing server, the token being previously purchased by the consumer and residing on a clearing server device. The update key is used as an authorization to modify the value of the token, i.e., to decrement and to increment. The merchant forwards the purchased merchandise to the consumer. When consumer discontinues making purchases at the selected merchant, the merchant returns the updated token to the clearing server. A new key is necessary to make the next purchase. This is the case even where the requesting merchant is the same as that from whom the last purchase was made. When the token is requested, if the token was used after its initial purchase, the present value of the token is made certain by receipt on the clearing server of informational downloads from the merchants.

New method of automotive tire pressure detection and safe identification

The invention provides a method for correspondingly marking the most protuberant part of the deformed rubber corresponding to the outer side of an automobile tire with a white fluorescent paint line and coating a red fluorescent paint line in the position which is one second distance below from the white line as a safety mark according to the allowable normal inflation pressure standard range calibrated when the tires of sedans and miniature vehicles leave the factory (for example, the allowable normal inflation pressure standard ranges of a 1.5t FIAT sedan, a 0.6t CHANG'AN STAR miniature minibus and a 1.0t LINGYANG sedan are respectively 2.3 to 2.8 Kg / cm<2>, 2.2 to 2.5Kg / cm<2> and 2.2 to 2.6Kg / cm<2>). When the red fluorescent paint line disappears and the most protuberant part of the deformed rubber on the outer side of the tire is above the white fluorescent paint line, the tire pressure is indicated to be too low, and measures, such as inflation, tire repair, etc., should be carried out. When the most protuberant part is below the white fluorescent paint line and above the red fluorescent paint line, the tire pressure is indicated to be too high, and the measure of deflation should be carried out. The method has the advantages of visibility, rapidness, convenience, safety, practicality and low cost, and is easily accepted by drivers and tire manufacturers, completed at one time in the tire manufacturer and easily generalized and applied.

Integrated digital transfusion apparatus and transfusion monitoring and management method thereof

The invention discloses an integrated digital transfusion apparatus and a transfusion monitoring and management method thereof. The integrated digital transfusion apparatus is mainly structurally characterized in that a shell of devices including a control system, a display and the like and a transfusion tube clip and device shell are respectively fixed onto an integrated transfusion support and device shell. A touch display, a microprocessor, a microphone/speaker, a scanner, a wireless network connection device, a miniprinter, a transfusion tube, a Murphy dripper clamping groove, a finger peristaltic pump, a photoelectric droplet detection device, a pressure detector and an ultrasonic bubble detector are mounted on the integrated digital transfusion apparatus. Data acquired by different parts in the transfusion apparatus are used for mutual comparison of transfusion parameters. Software computation and simulation techniques are used during transfusion, and nurses can well know detailed transfusion conditions of each patient in transfusion by directly observing simulated transfusion bottles/bags and tubes and simulated transfusion apparatuses on software of the transfusion apparatuses and software on external computers, setting operation of various transfusion parameters, setting alarm thresholds of the various transfusion parameters and the like.

Electric vehicle charge-discharge optimized dispatching method based on virtual electricity price

The invention provides an electric vehicle charge-discharge optimized dispatching method based on virtual electricity price. The method comprises the following steps: an electric energy public service platform predicts and samples the basic daily load information of a target area within an optimization time interval; when a new EV is connected to a charging pile within the target area, the network connection information of the new EV is read; a user input the charging information of the vehicle; an EV charge-discharge power model is constructed; virtual electricity price is calculated to indirectly reflect the load level of the target area; a dispatching model with the charge-discharge power as an optimization variable is constructed; dynamic time-of-use electricity price for user cost calculation is determined by combining wavelet analysis preprocessing and fuzzy clustering methods; the user makes an automatic response decision; a charge-discharge operation is performed on the EV according to the decision of the user and a plan is uploaded. The electric vehicle charge-discharge optimized dispatching method based on virtual electricity price is capable of realizing peak clipping and valley filling of EV cluster load and reducing the charge-discharge cost of the user on the basis of meeting the charging requirement of the user and the capacity limitation of a power distribution transformer. In case of a great EV cluster scale, the electric vehicle charge-discharge optimized dispatching method based on virtual electricity price is still capable of meeting grid side expectations.

Media device and method for interaction between media device and user

The invention relates to a media device and a method for the interaction between the media device and a user. The media device includes a touch screen for displaying an interaction interface; the interaction interface includes navigation bars; the navigation bars are a plurality of concentric semi-circles which are sequentially displayed from inside to outside in a cascading manner, and at least include a first-layer function key display area, a second-layer function key display area and a third-layer function key display area; the touch screen receives touch actions of the user, judges the touched navigation bar area, and feeds function keys corresponding to the touched navigation bar area back to a processing unit in the media device; and according to the received touch actions, the processing unit controls a display processing module in the media device to display or hide the navigation bars or the corresponding function key display area. In the invention, the navigation bars in the interaction interface are the concentric semi-circles which are sequentially displayed from inside to outside in a cascading manner, so that the navigation bars can bear more columns, the navigation layers are clear and visual, the user cost is reduced, and the user acceptance is higher.
