摘要:
Recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid using an extractive distillation column. The column yields a first residue that comprises ethanol, ethyl acetate, acetic acid, and water. The first residue is separated in a second column to yield a second distillate comprising ethanol and ethyl acetate. The second distillate is then separated in a third column to yield a third distillate comprising ethyl acetate and a third residue comprising ethanol.
摘要:
A process for removing water from an alcohol mixture, such as an ethanol mixture in the production of ethanol by hydrogenating acetic acid. The water is removed from a distillate of a first column using an adsorption unit, membrane, extractive column distillation, or a combination thereof.

A control arrangement for a vehicle includes an infotainment console having a user interface with a plurality of pushbuttons. A communication device is communicatively coupled to the infotainment console and relays signals between the infotainment console and a portable computing device. The infotainment console reconfigures the user interface to enable the user to control the portable computing device via the user interface. Each of the pushbuttons is actuatable to cause operation of the portable computing device to proceed to a respective application within the portable computing device.

A protective modular package cover has first and second fastening sections located at opposing first and second ends with one or more subassembly receiving sections disposed thereto and is configured to fasten the protective modular package cover to a core. Each fastening section has a foot surface located on a bottom surface of a fastening section and configured to make contact with the core, a mounting hole configured to receive a fastener, and a torque element. Each subassembly receiving section is configured to receive a subassembly and has a cross member formed along the underside of the protective modular package cover. Activation of the first torque element transfers a downward clamping force generated at the fastening element to a top surface of one or more subassemblies disposed in the one or more subassembly receiving sections via the cross member of each of the one or more subassembly receiving sections.
摘要:
A method and apparatus for transmitting audio information and digital images via a wireless switching network by performing the operations of starting a photo or audio session by a digital camera or audio appliance; connecting the digital camera or audio appliance to a wireless telecommunication terminal; reserving bandwidth on the wireless switching network; transmitting digital images or audio information between the digital camera or audio appliance and a centralized database via a first path on the wireless switching network; and establishing a second path for transmission of digital images or audio information upon the first path being interrupted using the reserved bandwidth for the second path.
摘要:
A method for operating a wavelength-converted light source includes directing a pump beam having a fundamental wavelength from the laser source into an input facet of the wavelength conversion device such that a wavelength-converted output beam is emitted from an output facet of the wavelength conversion device in the field of view of an optical detector. A physical property of the wavelength conversion device is varied within individual ones of a succession of consecutive speckle reduction intervals having durations less than the integration time of the optical detector. The physical property of the wavelength conversion device is varied by an amount that is sufficient to change in a phase-matched (PM) wavelength of the wavelength conversion device. The fundamental wavelength of the pump beam is thereafter adjusted based on the change in the PM wavelength to maintain an efficiency of the wavelength conversion in the wavelength conversion device.

A system and method are provided for a network-based content management system (CMS) for creating and sharing presentation objects, and for generating revenue based on providing access to tools by which the presentation objects are created, stored and managed. In the system, a content management service includes a database that stores a presentation object, and a Web server stores a Web page including a link to the presentation object. When the Web page is displayed on a computing device that accesses the Web page via the Web, the presentation object appears as an embedded presentation.

Techniques are described for dynamically generating recommendations for users, such as for products and other items. In at least some situations, the techniques include using multiple recommendation strategies, such as by aggregating recommendation results from multiple different recommendation strategies. Such recommendation strategies may have various forms, and may be based at least in part on data regarding prior interactions of numerous users with numerous items. In addition, information about current selections of a particular user may be gathered based at least in part on providing a GUI (“graphical user interface”) for display to the user that includes selectable information about numerous recommended items, and dynamically updating the displayed GUI with newly generated recommendations of items as the user makes selections of particular displayed recommended items (e.g., newly generated recommendations that are similar to the selected items in one or more manners, or are otherwise related to the selected items).
摘要:
A method and apparatus for launching a calibrator process by which the user is guided through the process of calibrating the conditions used by a particular print job is provided. Techniques are provided which calculate which print conditions will be used by the particular print job, which guarantees that the user is calibrating the correct conditions to get the best color quality for the particular job. The method and apparatus further provides techniques that allow the user to specify the conditions under which a calibration is considered expired in terms of time since the last calibration and the number of prints since the last calibration The method and apparatus further provides techniques for when the user encounters a new media type or print condition, the system can measure such and inform the user whether to create a new profile and/or new calibration set to get the optimal color quality.
