Abstract:
An electrical interconnect for a solid-oxide fuel cell stack assembly, including a novel sintering paste and an improved manufacturing process for an anode and cathode electrical contacts is disclosed. On the anode side, the paste contains a metallic oxide such as NiO, and an amount of sacrificial pore-forming particles, such as carbon particles or polymer spheres, which are vaporized during sintering of the paste, resulting in a very porous connection having good electrical conductivity and good adhesion. A preferred level of pore-former in the paste is about 40 volume percent. On the cathode side, the paste contains a noble metal such as for example, gold, platinum, palladium or rhodium, and an amount of the sacrificial pore-forming particles. The paste may be applied to the surfaces in a grid pattern or, because the resulting contact is porous after sintering, it may be applied as a continuous layer.

A method of passing user signals to a plurality of applications running with an operating system comprising receiving from each application information on user signals required by that application; saving in a memory the required user signals associated with each application; receiving a user signal from a user interface device; retrieving from the memory applications that require the received user signal; and sending the received user signal to each of the retrieved applications.
Abstract:
An apparatus and method for electrostatically coating a body surface with a coating composition. An apparatus of the present invention includes an enclosure, a mount positioned on the enclosure, and an electrostatic nozzle connected to the mount, the electrostatic nozzle adapted for passing the coating composition for deposition on the body surface. The apparatus further includes a floor surface within the enclosure, the floor surface having a resistive electrical connection.
Abstract:
A system and interface for trading financial instruments. The system consists of an intermediary computer system that is operable to communicate with one or more trader terminals utilizing either a private line, a network or the Internet. The intermediary computer system is comprised of one or more processors and storage media. The intermediary computer system communicates with trader terminals and displays to the trader terminals a listing of financial instruments, and information related to such financial instruments, that are available for trading. The intermediary computer system periodically updates the option adjusted price of financial instruments as to provide the traders with a time period in which the price will remain stable and during which time the traders can confidently execute orders based on the then available price. A timer, which is constantly visible to traders using the electronic trading system, displays the amount of time remaining until the displayed adjusted prices will be updated. The intermediary computer system is also operable to communicate directly with selected traders or groups of traders in the form of directed messages to the trader terminals.
Abstract:
An image processing method using an algorithm which incorporates simulated annealing by parallel Markov chains, the calculation of fitness values of states of the Markov chains which have substantially the same simulated annealing temperature, the calculation of the standard deviation of these fitness values, and the use of this standard deviation in setting the simulated annealing cooling schedule. The method may be used to delineate an object of interest in an image against a background by estimating the boundary of the object and optimizing the fit of the region within this boundary to the region occupied by the object.
Abstract:
An illustrative embodiment of a computer-implemented process for scalable group synthesis receives a group definition, applies a sub-set of conditions to the group definition to form a conditioned group definition, receives a set of entities and populates group membership using the received set of entities and the conditioned group definition, wherein each member responds in the affirmative to the sub-set of conditions.
Abstract:
An electronic trading system and method are disclosed for implementing an electronic trading protocol that permits buyers and sellers to “negotiate in the middle” or “NIM” i.e., to negotiate the purchase and sale of an item (e.g., securities) at a price between or equal to the best current bid and offer prices for the item through the submission of an initial NIM order and one or more NIM counteroffer orders. In a preferred embodiment, each NIM session may comprise two phases, a NIM private phase and a NIM public phase. During the NIM private phase, the initial NIM order is presented only to the trader on the opposite side of the market with the highest ranked order based on price and time priority. During the NIM public phase, the initial NIM order is presented to all traders on the opposite side of the market with pending orders at the best market price. The trader who submitted the initial NIM order is preferably granted authority to determine whether or not a public phase for the NIM should be allowed.
Abstract:
A coaxial jack has an electrically groundable housing including first and second ports, a printed circuit board supporting a terminating element and conductive traces, and a center conductor disposed within the electrically groundable housing. The center conductor extends through a hole in the printed circuit board and is normally coupled to the electrically groundable housing contact through the terminating element and the conductive traces. A grounding spring has a leaf spring that acts as switch to break the coupling when a plug is inserted into the first port.
Abstract:
A voice multi-tap apparatus for a communications system, the apparatus including an input connector (12) accommodating at least four input circuits, plurality of output connectors (13a-13d) incorporating respective output circuits coupled to respective input circuits; and at least one of said output connectors incorporating a second output circuit coupled to one of the input circuits via a switching device (14) whereby the operation of said switching device allows said at least one output connector service two circuits.
Abstract:
A method and apparatus for allowing a user to manually set a clock in a multi-format television receiver capable of receiving a plurality of television signals. The method comprises the steps of selecting a television signal from one of a plurality of television signals and then detecting temporal information in the television signal. Upon detecting such temporal information, the temporal information is extracted and used to set at least one clock to count time. Once the clock is set based upon the temporal information, the temporal information prevails over any manually set time, and the user is precluded from manually setting the clock. The television receiver continues to update the clock based upon the latest periodic temporal information periodically sent with the television signal. The user is permitted to manually set the time on a clock only in an instance where the updated temporal information has not been detected past a specified period of time.
