摘要:
The present invention provides process for preparing an alkylate comprising contacting in a reaction zone a hydrocarbon mixture comprising at least an isoparaffin and an olefin with an acidic ionic liquid catalyst under alkylation conditions to obtain an alkylate-comprising effluent, in which process: —solids are formed in the reaction zone; —a solids-comprising effluent comprising hydrocarbons and acidic ionic liquid is withdrawn from the reaction zone; and—at least part of the solids-comprising effluent is treated to remove at least part of the solids to obtain a solids-depleted effluent. The invention further provides a process for treating an acidic ionic liquid comprising at least 0.1 wt % of solids based on the total weight of the acidic ionic liquid, wherein at least part of the solids are removed.

A method includes defining a placeholder widget having a property and defining a prototype graphical user interface (GUI) having an instance of the placeholder widget. The method also includes presenting the prototype GUI to a user, where an appearance of the instance of the placeholder widget is based on the property of the placeholder widget. The method further includes replacing the instance of the placeholder widget in the prototype GUI with an instance of another widget. In addition, the method includes updating the presentation of the prototype GUI using the instance of the other widget. Replacing the instance of the placeholder widget with the instance of the other widget could include transforming an instance of a lower fidelity placeholder widget into an instance of a higher fidelity widget. The property of the placeholder widget could include a textual property, an image property, and/or a graphics property.

Disclosed is a silicon condenser microphone including a backplate having a plurality of perforations therethrough, a diaphragm opposed from the backplate for forming a capacitor. The diaphragm includes a first part and a second part received in the first part, the second part being capable of vibrating relative to the backplate. The first part is connected to the ground and the second part is connected to a bias voltage.
摘要:
A system and method for automatically generating an adaptive user interface for a plurality of appliances within a physical environment. Appliance description specifications of the appliances are generated from provided appliance functionality information and semantic information of related appliances and/or related environment information. The appliance description specifications can be analyzed to construct a semantic functionality relationship among the appliances and the adaptive user interface can be rendered based on an interface elements relationship which is a transformation of the semantic functionality relationship. The system has a user interface rendering module, which when run on a controller, implements the aforesaid appliance description specification generation and analysis, and adaptor modules, which when run on the appliances, maintain the appliance description specifications and allow exchange of same between the controller and appliances.
