The electrical stimulation signal is provided in an amount and manner adapted to increase the pH of the gastric acid in the patient's stomach and / or to decrease the amount of gastric acid produced thereby.

Plasma synthesis of lithium based intercalation powders for solid polymer electrolyte batteries

The invention relates to a process for preparing lithium intercalation compounds by plasma reaction comprising the steps of: forming a feed solution by mixing lithium nitrate or lithium hydroxide or lithium oxide and the required metal nitrate or metal hydroxide or metal oxide and between 10-50% alcohol by weight; mixing the feed solution with O2 gas wherein the O2 gas atomizes the feed solution into fine reactant droplets, inserting the atomized feed solution into a plasma reactor to form an intercalation powder; and if desired, heating the resulting powder to from a very pure single phase product.

Radio frequency receiver system for wideband signal processing

Wireless communication is ubiquitous today and deployments are growing rapidly leading to increased interference, increasing conflicts, etc. As a result monitoring the wireless environment is increasingly important for regulators, service providers, Government agencies, enterprises etc. Such monitoring should be flexible in terms of the networks being monitored within the wireless environment but should also provide real-time monitoring to detect unauthorized transmitters, provide dynamic network management, etc. Accordingly, based upon embodiments of the invention, a broadband, real-time signal analyzer (RTSA) circuit that allows for the deployment of RTSA devices in a distributed environment wherein determination of policy breaches, network performance, regulatory compliance, etc. are locally determined and exploited directly in network management or communicated to the central server and network administrators for subsequent action. Beneficially the RTSA exploits a broadband RF front end in conjunction with parallel direct down conversion and FFT techniques.

Apparatus and method for downhole well equipment and process management, identification, and actuation

A method for actuating or installing downhole equipment in a wellbore employs non-acoustic signals (e.g., radio frequency signals) to locate, inventory, install, or actuate one downhole structure in relation to another downhole structure. The method comprises the steps of: (a) providing a first downhole structure that comprises a non-acoustic (e.g., radio frequency) identification transmitter unit that stores an identification code and transmits a signal corresponding to the identification code; (b) providing a second downhole structure that comprises a non-acoustic receiver unit that can receive the signal transmitted by the non-acoustic identification transmitter unit, decode the signal to determine the identification code corresponding thereto, and compare the identification code to a preset target identification code; wherein one of the first downhole structure and the second downhole structure is secured at a given location in a subterranean wellbore, and the other is moveable in the wellbore; (c) placing the second downhole structure in close enough proximity to the first downhole structure so that the non-acoustic receiver unit can receive the signal transmitted by the non-acoustic identification transmitter unit; (d) comparing the identification code determined by the non-acoustic receiver unit to the target identification code; and (e) if the determined identification code matches the target identification code, actuating or installing one of the first downhole structure or second downhole structure in physical proximity to the other.

Method and system for upgrading a previously purchased media asset

Systems and methods for upgrading from one or more digital media assets to a set of digital media assets over a network are described. A potential purchaser can be notified of available upgrade opportunities that are available for purchase. The potential purchaser can elect to pursue an upgrade opportunity so as to purchase a set of digital media assets. Upon upgrading to the set of digital media assets, the digital media assets within the set of digital media assets are made available to the purchaser. Typically, on upgrading from one or more of the digital media assets in the set of digital media assets to the entire set of digital media assets, the purchaser pays a lower cost than would be otherwise charged if the purchaser were to purchase the set of digital media assets in a non-upgrade manner.
