Abstract: A system for processing purchase of commodities from a vending machine comprises a transaction detecting module, a control module, a transaction verification module, a display module, and a commodity dispensing module. In allowing one type of payment for commodities, the system prevents other payment types being used. The transaction module detects a transaction request and the control module obtains commodity information and a payment method that is user-selected, other payment methods then being forbidden. The transaction verification module verifies whether a payment is made under the selected payment method. If the payment is successful, the commodity dispensing module controls the vending machine to dispense commodity, if not, the display module controls a touch screen to output transaction failure information. A transaction method of the vending machine is also provided.

Abstract: A tool bit holder for connecting a rotary tool to a rotary tool driver. The tool bit holder including a body having a driver end configured to connect to a rotary tool driver and a tool end, a tool retainer bore, and a tool retainer movably received within the tool retainer bore and movable between an engaged position and a retracted position. The tool bit holder further includes an actuator sleeve, a sleeve spring for urging the actuator sleeve towards a first position, a plunger, and a plunger spring urging the plunger towards a loading position. A tool bit received in a tool receiving cavity pushes the plunger to a loaded position, and in the loading position the plunger extends over the tool retainer bore to engage the tool retainer and urge the tool retainer towards the retracted position.

A horizontal slide signal along a touchscreen or a vertical slide signal along the touchscreen entered by using the touchscreen is obtained; a current display area of the touchscreen is divided, according to the horizontal slide signal, into at least two display windows arranged up and down, or a current display area of the touchscreen is divided, according to the vertical slide signal, into at least two display windows arranged side by side, thereby implementing that multiple application programs are simultaneously displayed on a screen up and down or side by side, and a user does not need to frequently switch between programs, which facilitates user operations.

Abstract: A method and system for evaluating fitness between a wearer and eyeglasses worn by the wearer, the method comprising steps of: generating facial attribute data associated with the wearer; generating attribute data of the eyeglasses; establishing wearer model based on the facial attribute data; establishing eyeglasses model based on the eyeglasses attribute data; comparing the wearer model and the eyeglasses model and evaluating the fitness there between; and generating a rating score information indicative of to which extent the eyeglasses improves the wearer visage based on the fitness evaluation result. By means of this method, the wearer of the eyeglasses can easily learn the matching/fitness degree of the eyeglasses worn by the wearer with his or her face, so as to help the wearer to decide whether or not to purchase or use the eyeglasses.

Abstract: A computer-implemented method includes defining respective positions of a first set of nodes and a second set of nodes in an enrichment region, and performing a coupled pore fluid diffusion and stress analysis on the enrichment region at the first set of nodes. It is then determined whether the second set of nodes is activated—representing a fracture—as a result of the analysis, and the results are visually output to a user.
