Abstract: A method and apparatus for securing the game program software and related data files used by a gaming device and for authenticating such files during game startup and play. In one embodiment of the present invention, a verification code is generated by the manufacturer for each software file and data file used by the game. The verification codes are stored in a non-volatile, tamper-proof, read-only memory device securely attached to the gaming device. On the occurrence of certain pre-defined events, the stored verification code is used to validate the game software and data files. Verification consists of calculating a live verification code for some or all of the software and data files present in the alterable random access memory using the same method chosen to create the stored verification code. In some embodiments of the present invention, the verification code is the result of a hash function of trusted copies of each software and related data file.

Abstract: The invention relates to a method and device for separating materials in the form of particles and/or drops from a gas flow, in which method the gas flow is directed through a collection chamber the outer walls of which are grounded, and in which high tension is directed to the ion yield tips arranged in the collection chamber, thus providing an ion flow from the ion yield tips towards the collection surfaces, separating the desired materials from the gas flow. It is characteristic of the invention that the collection surfaces conducting electricity are electrically insulated from the outer casings; and that high tension with the opposite sign of direct voltage as the high tension directed to the ion yield tips is directed to the collection surfaces. According to an embodiment of the invention the electrical insulation is made of ABS, and the surface conducting electricity comprises a thin chrome layer arranged on the insulation layer.

Abstract: A preferred embodiment of a stent provides a folded strut section that provides both structural rigidity and reduction in foreshortening of the stent mechanism. A flexible section provides flexibility for delivery of the stent mechanism. In a second embodiment, flexible section columns are angled with respect to each other, and to the longitudinal axis of the stent. These relatively flexible sections are oppositely phased in order to negate any torsion along their length. In yet another embodiment, the flexible connector can take on an undulating shape (like an "N"), but such that the longitudinal axis of the connector is not parallel with the longitudinal axis of the stent. Finally, a new method is disclosed for making stents. The method consists of performing a standard photochemical machining process of cutting, cleaning and coating the tube with a photoresist. However, unlike former methods, the photoresist image is developed on the surface of the cylindrical metallic tube, which results in a controlled variable etching rate at selected sites on the cylindrical metallic tube during the etching process. Further embodiments provide living hinge connectors and connections along the length of the radial strut member.

Granted: 2012-03-13
Abstract: An oilfield data analysis system is based on a four-tier software model which includes a "shared earth model" and a federation of "directory services". The first tier is a universal graphical user interface (GUI) which can operate on any inexpensive computer (12) as well as on an expensive workstation (14), i.e. a "web browser". The second tier is an application server (18) which is coupled to users via the worldwide web and serves geoscientific software applications. The third tier is a geometric modelling system (20) where geometric data is stored and processed. The third tier embodies the "shared earth model". The fourth tier is a database management system (22) where non-geometric data is stored. According to the invention, there can be (and preferably are) multiple instances of each tier. Communication of data between different tiers is accomplished via XML data exchange. According to a presently preferred embodiment, the geoscience applications served by the second tier are written as JAVA servlets and applications may communicate with each other without human direction by registering requests with "directory services". Applications interested in certain types of data "listen" for "data events" being registered with directory services. The cost of utilizing an application can be based on a time-rental billing operation which is carried out automatically via directory services.

Abstract: A process for treating an ammonia-containing wastewater, which comprises the steps of contacting an ammonia-containing wastewater A with steam C (carrier gas) in a stripping column (7) to transfer NH3 to a gas phase from the ammonia-containing wastewater A; heating the resultant gas containing NH3 in a preheater (11)and then contacting the gas with a catalyst layer (13) to decompose NH3 into nitrogen and water; measuring the NOx (or N2O) content of the gas generated in the above decomposition step; and adjusting, based on the measured values of the NOx (or N2O) content, one or more of (a) the feed rate of the ammonia-containing wastewater, (b) the NH3 content of the ammonia-containing wastewater and (c) the flow rate of the gas containing NH3 to be contacted with the catalyst layer [when the N2O content is measured, one or more of the flow rate of the carrier gas, the flow rate of an added gas such as air, and the flow rate of the part of the gas generated in the above decomposition step to be recycled to the catalyst layer]. The process is advantageous in that an extremely small amount of hazardous substances such as NOx is discharged even at the start of an apparatus for the process or when the NH3 content of a gas is considerably changed.

Abstract: In a non-volatile passive matrix memory device (10) comprising an electrically polarizable dielectric memory material (12) exhibiting hysteresis between first and second sets (14; 15) of addressing electrodes constituting word lines (WL) and bit lines (BL) of the memory device. A memory cell (13) is defined in the memory material (12) at the overlap between a word line (WL) and a bit line (BL). The word lines (WL) are divided into segments (S) each segment sharing and being defined by adjoining bit lines (BL). Means (25) are provided for connecting each bit lines (BL) of a segment (S) with a sensing means (26) enabling simultaneous connections of all memory cells (13) of a word line segment (15) for readout via the bit lines (BL). Each sensing means (26) senses the charge flow in a bit line (BL) in order to determine a stored logicalvalue. In a readout method,a word line (WL) of a segment (S) is activated by setting its potential to a switching voltage Vs of the memory cell (13) during at least a portion of a read cycle, while keeping the bit lines (BL) of a segment (S) at zero potential, during which read cycle a logical value stored in the individual memory cells (13) is sensed by the sensing means (26).
