摘要:
A live streaming system/method provides cross platform live streaming capabilities to mobile devices. A file format compatible with legacy HTTP infrastructure is used to deliver media over a persistent connection. Legacy client media players can dynamically change the encoded rate of the media delivered over a persistent connection. Standard HTTP servers may be used without modification, leveraging standard media players embedded in mobile devices for seamless media delivery over wireless networks with high bandwidth fluctuations.

A method and system for generating power in a vaporization of liquid natural gas process, the method comprising pressurizing a working fluid; heating and vaporizing the working fluid; expanding the working fluid in one or more expanders for the generation of power, the working fluid comprises: 2-11 mol % nitrogen, methane, a third component whose boiling point is greater than or equal to that of propane, and a fourth component comprising ethane or ethylene; cooling the working fluid such that the working fluid is at least substantially condensed; and recycling the working fluid, wherein the cooling of the working fluid occurs through indirect heat exchange with a pressurized liquefied natural gas stream in a heat exchanger, and wherein the flow rate of the working fluid at an inlet of the heat exchanger is equal to the flow rate of the working fluid at an outlet of the heat exchanger.
摘要:
A live streaming system/method provides cross platform live streaming capabilities to mobile devices. The live streaming system includes a live streaming recorder operative to (1) capture a live media stream generated by a live media source and save the captured live media stream as a recorded stream in a recorded media file, and (2) transcode the recorded stream into a plurality of transcoded media files of respective different media encoding formats. The system further includes a stream distribution subsystem operative to generate a plurality of distributed media streams each generated from one or more of the transcoded media files, each distributed media stream being delivered to a corresponding set of the mobile endpoint devices.

A reflector-solar receiver assembly and methods related to the reflector-solar receiver assembly are described. The reflector-solar receiver assembly contains a reflector and a solar receiver. The reflector has a substantially planar light reflecting face and the solar receiver has a substantially planar light receiving face. The normal direction of the light reflecting face and the normal direction of the light receiving face are at an angle of about 90°. The reflector-solar receiver assembly can be installed at an installation site by placing the substantially planar light reflecting face at an angle of about γ−23.5° or about γ+23.5° from the gravitation line of the installation site, γ is the latitude of the installation site, so that the substantially planar light reflecting face reflects at least a portion of sunlight to the substantially planar light receiving face during a majority of the clear days of a year.

A process for producing a high temperature COx-lean product gas from a high temperature COx-containing feed gas, includes: providing a sorption enhanced reactor containing a first adsorbent, a shift catalyst and a second adsorbent; feeding into the reactor a feed gas containing H2, H2O, CO and CO2; contacting the feed gas with the first adsorbent to provide a CO2 depleted feed gas; contacting the CO2 depleted feed gas with the shift catalyst to form a product mixture comprising CO2 and H2; and contacting the product mixture with a mixture of second adsorbent and shift catalyst to produce the product gas, which contains at least 50 vol. % H2, and less than 5 combined vol. % of CO2 and CO. The adsorbent is a high temperature adsorbent for a Sorption Enhanced Reaction process, such as K2CO3 promoted hydrotalcites, modified double-layered hydroxides, spinels, modified spinels, and magnesium oxides.

摘要:
A pressure swing adsorption process includes providing a pressure swing adsorption apparatus having six beds, and equalizing a pressure of each of the six beds in four steps, wherein at all times during the process, at least one of the six beds is providing offgas. The process is particularly suitable for purifying hydrogen from a feed gas mixture containing hydrogen and at least one of methane, carbon dioxide, carbon monoxide, nitrogen and water vapor.
摘要:
A safety system for grounding an operator at a fueling station prior to removing a fuel fill nozzle from a fuel tank upon completion of a fuel filling operation is provided which includes a fuel tank port in communication with the fuel tank for receiving and retaining the nozzle during the fuel filling operation and a grounding device adjacent to the fuel tank port which includes a grounding switch having a contact member that receives physical contact by the operator and where physical contact of the contact member activates the grounding switch. A releasable interlock is included that provides a lock position wherein the nozzle is locked into the port upon insertion of the nozzle into the port and a release position wherein the nozzle is releasable from the port upon completion of the fuel filling operation and after physical contact of the contact member is accomplished.
摘要:
A pressure swing adsorption process including an adsorption apparatus having a plurality of beds and counter-currently purging at least two of the beds simultaneously throughout the process. The number of beds and number of pressure equalization steps are not particularly limited, but a ten-bed, four pressure equalization step process in advantageous. In addition, other ten-bed, four pressure equalization step processes are disclosed which do not counter-currently purge at least two of the beds simultaneously, but which have an average of at least two of the ten beds being simultaneously regenerated by simultaneously providing off-gas from a feed end of each of the beds to an off-gas line.
摘要:
The present invention is an improvement to a cryogenic distillation process for the separation of air into its constituent components. The present invention process uses a distillation column system which comprises at least two distillation columns wherein the top of the higher pressure column is in thermal communication with the lower pressure column. The distinctive feature and improvement of the present invention comprise: (a) condensing a portion of the compressed, contaminant-free, feed air by appropriate means, such as against vaporization of liquid oxygen or other source of refrigeration; (b) using at least a portion of this liquid air as impure reflux in one of the distillation columns, and (c) removing a waste vapor stream from a location situated no more than four theoretical stages above the location where the liquid air is fed to the column, such that this waste vapor stream has a nitrogen mole fraction of less than 0.95.
