Filed: 2011-05-13
Abstract: A jointing adhesive for stone is provided, characterized in that it at least comprises 100 parts by weight of an air-dried unsaturated polyester resin, 0 to 5 parts by weight of hydrogenated castor oil, 1 to 20 parts by weight of a nano powder, 0 to 100 parts by weight of a filler and 1 to 15 parts by weight of an antishrinking agent. It overcomes disadvantages of a conventional jointing adhesive made by common marble glue, such as low air drying performance, low anti-shrinking capacity, low permeability and the like. The jointing adhesive for stone has the advantages of high permeability, non-stick property after being cured, high anti-shrinking capability, luminance after being polished and the like. The stone jointing adhesive enriches the variety of the marble glue and solves the jointing problem between stones.

Inventor: MUELLER EUGENE
IPC: G06Q40/00
Filed: 2011-06-01
Abstract: A calendar spread futures contract is a forward contract on the intermonth spread of futures contracts. The calendar spread futures contract can be independently traded and accounted for independent of the traditional roll periods of the complementary futures contracts. An open interest holder can hedge against price volatility in the related futures contracts that may occur prior to or during the roll period. In other words, the calendar spread futures contract locks in the current spread between the front-month contract and the first-deferred contract. Buying a calendar spread futures control is equivalent to buying the spread difference between the expiring contract and the second expiry. Selling a calendar spread futures contract is equivalent to selling the spread difference between the expiring contract and the second expiry.

Abstract: Methods and constructs for the introduction of multiple genes encoding enzymes in a multi-enzyme biosynthetic pathway are provided. In one embodiment, the constructs contain two or more enzyme-encoding genes, each under the control of an inducible promoter and each with a polyadenylation signal. The constructs are used to produce transgenic plants, in which the expression of the enzymes are increased when a chemical inducing agent is applied, and a biosynthetic product of the series of enzymes encoded by the transgenes is produced. Constructs may be used which contain two or more enzyme-encoding genes under the control of one or more promoters activated by activator molecules or complexes expressed from a transgene or transgenes, which are themselves under the control of one or more inducible promoters and switched on following the external application of a chemical ;  The transgene or transgenes expressing the activator molecules or complexes may be included in the same construct containing multiple genes encoding enzymes in a multi-enzyme biosynthetic pathway. Alternatively, the transgene or transgenes expressing the activator molecules or complexes may be on a different construct from the construct containing multiple genes encoding enzymes in a multi-enzyme biosynthetic pathway. The activator molecule can be expressed using a constitutive promoter in an inactive form which is converted to the active form following application of the chemical inducing agent.

Abstract: In a method of digital communication where the transmitter includes a pulse-shaping filter and the receiver includes a plurality of corresponding matched filters, the pulse shaping filter is approximated to match a plurality of filters of the receiver for reducing the number of transmit shaping filters. The filter comprises a square-root raised cosine (SRRC) filter where the SRRC filter amplitude/phase response is approximated using a typical Parks-McClellan (remez) algorithm for designing linear phase FIR filters which, for a given set of input parameters, outputs a transmit filter coefficient set for the SRRC filter. The input parameters to the Parks-McClellan algorithm are chosen by iteration such that pass-band ripple, 3-dB point, and stop-band attenuation of the transmit filter meet or exceed specification requirements while the resulting transmit-receive filter pair ISI is minimized across a plurality of matched filter specifications.

IPC: H04W24/00
Filed: 2007-12-19
Abstract: Methods and apparatus for increasing diversity gain at a receiver by applying beamforming to transmit diversity space-time coded signals. A  transmit signal is space-time coded over a plurality of space-time antenna groups, with each space-time antenna group associated with a specific space-time code. The signal at each space-time antenna group is beamformed over the plurality of antennas in the space-time antenna group. Each of the plurality of antennas in a space-time antenna group is weighted with a distinct weight, relative to the other antennas in the space-time group. The beamforming weights can vary based on a channel quality feedback indication from a receiver. The amplitude, phase, or a combination of amplitude and phase of each weight or of a vector of multiple weights can vary as a function of the channel quality indication in order to improve the quality of the recieved signal.
