Abstract: A multiplexer circuit includes a plurality of switch circuits coupled between respective input nodes and an output node. The switch circuits include first and second switch elements coupled in series, at an intermediate node, between the respective input node and the output node. A third switch element is coupled between an output of a buffer and the intermediate node. The buffer is configured to generate a buffered voltage based on the output voltage. When a particular switch circuit is selected, its respective first and second switch elements are active while its third switch element is inactive, resulting in a path between its input node and the output node. When the particular switch circuit is not selected, its third switch element is active while its first and second switch elements are inactive. The buffered voltage is driven to the intermediate node via the active third switch element.

Abstract: The present disclosure provides a method for calculating wellbore friction resistance of a foam drainage gas production well. It is based on the conversion of the parameters of the gas-liquid two-phase flow Mukherjee & Brill model, it defines the liquid film reversal point as the zero friction resistance point, ignores the influence of the negative value of friction resistance, and uses this as a starting point to predict the change of friction resistance. The influence of liquid phase parameters and foaming agent concentration is taken into account in the friction resistance coefficient. An effective calculation method is obtained by combining the experimental data fitting and optimization. The present disclosure better characterizes the wellbore flow condition of the foam drainage gas production well, and provides important theoretical support for the prediction of the wellbore pressure drop of the foam drainage gas production well.

Abstract: A computer representation of a printable product part and a plan for the printable product part to be deposited using an additive manufacturing process are received. The printable product part comprises an accumulation of material deposited by the additive manufacturing process. The plan comprises a tool-path representation of the printable product part and process parameters. A plurality of as-printed shapes of the printable product part are determined after it has been deposited according to the plan. Geometric differences between any of the plurality of as-printed shapes with the computer representation of the product part are determined.

Abstract: The invention relates to the technical field of robotics, in particular to a fully-automatic intelligent multi-wok cooking method. The cooking method is characterized in that it includes at least the following steps: a driving mechanism drives the cooking woks to the food ingredient storage and supply system for ingredient fetching; after ingredient fetching action is completed, the cooking woks are heated while being rotated for wok tossing; wok moving, ingredient fetching, wok heating and tossing repeats until cooking completes, the cooking wok(s) is(are) then driven to the product delivery system for dishing. The said cooking method has the advantages that: fully-automatic cooking process is realized, including various functions such as stir frying, stewing, washing, dishing and etc.

Abstract: A hand-writing input device comprises: an input surface, a guidance device provided on the input surface along a predetermined track to guide a finger or pen along the track; a plurality of switch elements provided at particular positions on the track. When a particular character is inputted, the triggered switch element outputs the corresponding signal, and the combinations of the signals outputted by the switch elements correspond to the inputted characters. Since hand-writing input is performed by guiding a finger or pen along a predetermined track, only few switch elements are needed, thereby simplifying hand-writing recognition, reducing software requirements and increasing recognition accuracy.
