Title: Statistical multiplexer and remultiplexer that accommodates changes in structure of group of pictures
Inventor: WANG LIMIN
IPC: H04N7/26
Filed: 2001-05-02
Abstract: A system for rate control during transcoding and encoding of digital video data in a multi-program transmission environment accommodates changes in the  GOP structure of any of the programs, e.g., due to a commercial insertion or  the like. A hierarchical bit allocation scheme is used, where bits are allocated on a super group of pictures (GOP) level (106), i.e., a grouping o f multiple GOPs, a super frame level (104), and an individual frame level (102 ). The bit allocation for the super GOP and each picture is adjusted when a change in the structure of a group of pictures (GOP) is detected for any of the pre-compressed programs. The super GOP length may also be adjusted if required to maintain an integer number of GOPs therein. A change in the GOP structure is detected based on a change in the GOP length or sub_GOP length (distance between P pictures). For pre-compressed data, initial GOP lengths and sub_GOP lengths can be assumed and adjusted as required based on actual measurements. For a current I or P picture, the sub_GOP length is calculated  based on temporal references of the current picture and a previous I or P picture. For a current B picture, the same calculation is used, plus one picture.

Inventor: RAUCH SOL
IPC: G01S13/32
Filed: 2002-10-22
Abstract: A spread spectrum radar system, characterized in that the receive radar signal is mixed down to baseband and applied to leak cancellation means for subtracting therefrom an attenuated delayed version of the transmit radar signal to provide a reflected receive radar signal with improved signal-to-noise ratio for further processing and to prevent receiver saturation. The radar allows the capture of the range and speed of identified targets, and facilitates a determination of the target's direction. It exhibits an inherent immunity to electromagnetic interference, and is relatively undetectable by radar detectors. The system is easily reprogrammable for different range resolutions and permits Doppler processing to be independent of the angle between radar signal and the track of the target.

Abstract: A semi-closed combined cycle system (100) is provided which converts an open cycle gas turbine (10) into a non-polluting power system. The prior art gas turbine (10) includes a compressor (20) which compresses air (A') and combusts the air (A') with fuel. Combustion products form the exhaust (E') which is expanded through the turbine (40). The turbine (40) drives the compressor (20) and outputs power. The exhaust (E') exits the turbine (40) and can be routed through a heat recovery steam generator (50). The exhaust (E') is routed to a divider (110) which has two outlets including a return duct (120) and a separation duct (130). The return duct (120) routes a portion of exhaust (E') back to the compressor (20), and a duct (150) adds oxygen to the exhaust (E').

IPC: C08F4/02
Filed: 2001-05-23
Abstract: A process is provided for producing a polymer composition. The process comprises contacting a narrow molecular weight distribution base polymer and a high molecular weight polymer component. The base polymer is an ethylene polymer having a Mw/Mn less than about 5 and a melt flow index from about 0.2 g/10 min to about 20 g/10 min. The high molecular weight polymer component has a molecular weight distribution such that at least a substantial portion of its molecules have a molecular weight of greater than one million. The high molecular weight polymer component being incorporated is in an amount to give about 0.1 % to about 10 % by weight, based on the total weight of the polymer composition, of the molecules having a molecular weight greater than one million. The polymer composition has a higher bulk density than the base polymer. In addition, when the polymer composition is blown into film, the film has improved clarity over the base polymer.

Title: Gibberellin 2-oxidase gene, functions and uses thereof
Inventor: SAITO TAMIO
IPC: C12N15/82
Filed: 2003-03-19
Abstract: An objective of the present invention is to provide DNAs encoding novel plant proteins having a gibberellin (GA) 2-oxidation activity.      Another objective is to modify plant height by utilizing these DNAs for regulating the gibberellin content.      PCR was performed using degenerate primers, and novel OsGA2ox2 and OsGA2ox3 genes were obtained. The present inventors discovered that unlike products of other GA2-oxidases such as OsGA2ox1, the product of OsGA2ox3 catalyzes the two-step oxidation of GA20 to GA29 and then of GA29 to GA29-catabolite. In addition, the present inventors also found that the growth of the transgenic rice plants expressing OsGA2ox3 was suppressed as compared to control plants.

Title: Method and apparatus for measuring and orienting golf club shaft
Inventor: WEISS RICHARD M
IPC: A63B53/10
Filed: 2001-11-09
Abstract: The preferred orientation, or planar oscillation plane, of a golf club shaft (110) is located by measuring the oscillation (20, 21) of the shaft (110) when an impulse is applied. Preferably, the out-of-plane oscillation is measured at a large number of angular positions about the shaft (110) axis, and the principal planar oscillation plane is identified by that pair of opposed angular positions in which the out-of-plane oscillation is smallest. The location of the preferred orientation may be marked on the shaft (110) and used to assemble a golf club with the planar oscillation plane in a predetermined orientation. The staightness of the shaft (110) can also be determined by deriving its spring constant from its oscillation frequency and then measuring the restoring force when the shaft is deflected by the same nominal amount at different angular positions; differences in restoring force can be attibuted to differences in actual deflection distance resulting from lack of straightness.

Abstract: Les systèmes MIMO de l'art antérieur utilisaient des antennes à variations spatiales pour ne pas réduire le nombre de canaux orthogonaux que l'on peut obtenir. Selon la présente invention, on obtient ainsi des antennes de grande taille par rapport aux systèmes d'antennes à multiples faisceaux qui utilisent des antennes étroitement espacées. Pour obtenir un ensemble d'antennes compact, tout en pouvant encore exploiter un système MIMO, la présente invention se fonde sur le principe selon lequel seule la diversité de polarisation peut être utilisée dans un système MIMO sans nécessiter d'antennes à variations spatiales. On utilise des antennes étroitement espacées, ce qui permet d'obtenir une antenne de système MIMO compacte. En outre, ces systèmes MIMO avec une variation de polarisation mais sans variation spatiale peuvent être utilisés de manière avantageuse dans des lignes de visée et combinées également à des systèmes d'antennes à multiples faisceaux pour augmenter la capacité.
