摘要:
The disclosed embodiments relate to systems and methods for determining a quotation price of a spread between multiple products, such as two or more futures contracts, having non-homogeneous construction, e.g. one may be specified in terms of an implied rate, such as a Eurodollar Futures contract, and the other may be specified in terms of a price, such a U.S. Treasury Futures contract. The disclosed embodiments normalize the valuation of each “leg” of the spread with respect to each other, accounting for the divergence of the underlying contract construction, so that a difference in those valuations may be computed.

An electronic trading system utilizes a Match Engine that receives orders, stores them internally, calculates tradable combinations and advertises the availability of real and implied orders in the form of market data. New tradable items defined as combinations of other tradable items may be included in the calculation of tradable combinations. A technique is disclosed for suppression of the calculation and/or subsequent listing of an implied order when the order is either undesired or unnecessary in the market therefore.

Disclosed is a parallel processor packaging structure and a method for manufacturing the structure. The individual logic and memory elements are on printed circuit cards. These printed circuit boards and cards are, in turn, mounted on or connected to circuitized flexible substrates extending outwardly from a laminate of the circuitized, flexible substrates. Intercommunication is provided through a switch structure that is implemented in the laminate. The printed circuit cards are mounted on or connected to a plurality of circuitized flexible substrates, with one printed circuit card at each end of the circuitized flexible circuit. The circuitized flexible substrates connect the separate printed circuit boards and cards through the central laminate portion. This laminate portion provides XY plane and Z-axis interconnection for inter-processor, inter-memory, inter-processor/memory element, and processor to memory bussing interconnection, and communication. The planar circuitization, as data lines, address lines, and control lines of a logic chip or a memory chip are on the individual printed circuit boards and cards, which are connected through the circuitized flex, and communicate with other layers of flex through Z-axis circuitization (vias and through holes) in the laminate.

A powered air purifying respirator (PAPR) assembly and kit therefore has an elongated hollow belt body having open first and second ends and multiple inlet openings along its length for mounting one or more filter canisters, one or more filter canisters for mounting in the inlet openings for supplying purified air to the interior of the belt body, a motor and driven fan assembly having a fan inlet in communication with each filter canister through the hollow belt body and a fan outlet; and a power source operably mounted to the belt body and connected to the motor. The PAPR assembly forms a portion of a belt or bandolier to be worn around the user's waist, back, or other location, and at least the belt body can be made of a flexible rubber material, such as a Butyl and Silicone blend, or any other suitable material to conform the PAPR belt to the user's body.

A method and structure is disclosed for forming a removable interconnect for semiconductor packages, where the connector is adapted to repeatedly change from a first shape into a second shape upon being subjected to a temperature change and to repeatedly return to the first shape when not being subjected to the temperature change. The connector can be disconnected when the connector is in its second shape and the connector cannot be disconnected when the connector is in its first shape.
摘要:
A modular powered air purifying respirator (PAPR) which is comprised of a fan, motor, scroll, and power source mounted within one housing, and which accepts either traditional or conformal filters. Ambient air is drawn into the PAPR module through the attached filter by a fan, which is driven by direct connection to a motor. The pressurized air is then accelerated by an optimized scroll to the outlet in the PAPR housing. The PAPR module can be employed in multiple use configurations. The PAPR module further comprises a removable battery pack module that is easily retained to/removed from the PAPR module, enabling a user to be able to quickly remove a spent battery pack module and install a fresh battery pack module, thereby replacing the batteries within one breath cycle.

摘要:
A locking device for multiple-section telescoping tubes wherein a smaller tube is telescopically retractable into or extensible from within a larger tube includes a pair of opposing blocks, disposed within the telescoping tubes, one block being attached to the smaller tube, the other block being configured to move laterally with respect to the first block when the blocks are moved longitudinally with respect to each other. Depending on the direction of longitudinal movement of the blocks, one block may be caused to bear against an inner side of the larger tube to resist retraction of the smaller tube, or the blocks may be allowed to move away from the inner side of the larger tube to allow free sliding extension of the smaller tube. The device also includes means for selectively longitudinally moving one of the blocks with respect to the other, so as to allow free sliding retraction of the smaller tube, when desired.
