摘要:
A method for cleaning a ceramic membrane used in an oil recovery process. The cleaning method includes online and offline modes. In the online mode, the method includes periodically backflushing the ceramic membrane with an aqueous media. In the offline mode, the method includes backpulsing or statically cleaning the ceramic membrane by utilizing an aqueous alkaline media, an aqueous acidic media, and a liquid hydrocarbon solution.

The present invention provides systems and methods for distributing coupons by a retailer. The coupons distributed in the invention are “third-party” coupons, that is, coupons for goods or services that are unrelated to those of the retailer and offered by a third-party retailer. For example, if the coupons are being distributed by a supermarket, then the coupons may be for tools at a home-improvement store or for tax services by an accountant. The distribution methods of the invention increases the revenue of a retailer. More specifically, a consumer is presented a coupon when the value of the transaction exceeds a threshold. In a number of embodiments, the threshold is the average sale per transaction of the retailer. Accordingly, consumers will be motivated to increase spending so that coupons can be earned. The methods and apparatus of the invention are equally applicable to both “brick and mortar” and “click and mortar” retailing. In the latter, consumers may shop on the Internet and print out coupons during checkout if the threshold for a particular website is met.
摘要:
A validation method for validating IP information header in data packets from user equipment connected to a mobile telecommunications network (1) and accessing an IP network (5) through a proxy. In the method trusted location information of the user equipment (2) from a trusted source of the telecommunications network is requested (109). Then, the trusted location information is inserted into the IP information header of a message (112) to be sent to a location based function (17).

A method and system for treating water in order to desalinate the water where the system and method includes a reverse osmosis or distillation unit for producing a first concentrate and at least partially desalinated water. The first concentrate stream is directed to a first demineralization unit which utilizes nanofiltration membranes to treat the first concentrate stream so as to produce a permeate and a second concentrate stream. The second concentrate stream is directed to a second demineralization unit that includes an ion exchange device which in turn treats the second concentrate stream by producing a stream of at least partially demineralized water and third concentrate stream. The stream of at least partially demineralized water is mixed with the stream of at least partially desalinated water produced by the reverse osmosis or distillation unit.

A poppet valve engine incorporates a single rotary combustion chamber serving multiple cylinders to decrease emissions and increase thermodynamic efficiency. Virtually zero emissions are achievable by on-board fuel reforming to hydrogen. Limited heat range exposure of the rotary combustion chamber, low temperature combustion, and ceramic coatings reduce heat loss while three stage combustion, intake and fuel preheating, and fuel reforming reduce combustion process irreversibility. A supercharger increases the power density to allow engine displacement reduction. A z-crankshaft assembly coupled with a pre-combustion chamber allow knock-less and stable hydrogen combustion at virtually all load and speed conditions. Variable compression, possible in certain configurations of the z-crankshaft assembly, further increases thermal efficiency.
摘要:
A power-saving synchronization of refresh requesting messages transmitted from a client terminal (31) to different server terminals (33a, 33b) in multiple soft-state dialogues, e.g. in SIP. The synchronization involves a continuous detection of a large time offset (34) occurring between the refresh requesting messages in the different dialogues, and an adjustment of the negotiated length of the refresh interval indicated in the refresh requesting messages, such that the client terminal will transmit the refresh requesting messages approximately simultaneously to the different server terminals.
摘要:
In one embodiment, a method of transmitting system information on a down link shared channel structured as successive subframes includes transmitting (400-416) system information in regularly occurring time windows, each time window spanning some number of successive subframes. The method further includes indicating (406/408) to receiving user equipment (120) which subframes within a given time window carry system information. The method and variations of it are applied, for example, to the transmission of dynamic system information on the down link shared channel or other down link channel in a 3GPP E-UTRA wireless communication network (100).
摘要:
An application server (102) along with various other devices and method are described herein for managing a service (e.g., communication service) which is provided to a user. As described herein, the application server with the help of aspect oriented programming is capable of automatically adding functionality to an original service without directly modifying the target application code of the original service. In particular, the application server when automatically adding functionality to a certain application can automatically detect which features are still missing within the certain application, and which are already supported.
摘要:
According to the invention a core network management device (32) in a core network section (CN) of the wireless network (WN) receives a request for a tracing regarding a wireless terminal (16). The request includes an address of a destination device (26) that is to receive trace log data or data enabling the locating of the address. The core network management device (32) then automatically orders, based on the request, network elements (10, 12, 14, 20, 22, 24) of an access network section (AN) of the wireless network (WN) to perform tracing regarding the wireless terminal (16) and ensures that the trace log data is sent to the destination trace log data handling device (26). The request with the address may be sent from an access network management device (26) in the access network section (AN).
