Inventor: LARKIN BRYAN JAMES
IPC: B64C11/48
Filed: 1995-09-22
Abstract: La présente invention concerne une unité de propulsion marine comportant deux hélices contrarotatives (15, 16) mues par un seul arbre (25) grâce à une pignonnerie se composant d'un ensemble de planétaires statiques (40), d'un pignon externe (30) et d'un pignon interne (44). La pignonnerie est montée dans une boîte remplie d'huile comportant trois segments cylindriques coaxiaux (12, 13, 14). Les deux segments extérieurs (12, 14) tournent en sens opposés et constituent chacun un moyeu d'hélice. Le segment intermédiaire (13), qui est stationnaire, sert de support pour les planétaires, et sert de monture pour des ailettes de rectification d'écoulement (18), laquelle monture supporte un carénage cylindrique (17). Un passage angulaire (28) peut être ménagé dans le segment intermédiaire (13) pour évacuer les gaz de combustion au travers d'orifices pratiqués dans la partie extérieure du carénage (17) lorsque l'unité est intégrée à un moteur hors bord.

Abstract: De manière à prévenir la conception et/ou le développement de maladies sexuellement transmissibles (MST), on administre dans le vagin, avant un rapport sexuel, une ou plusieurs lectines capable de fixer le sperme et/ou les micro-organismes pathogènes responsables des MST. Les lectines immobilisent le sperme, le privent de sa capacité de fertilisation et se fixent également aux micro-organismes pour les rendre non pathogènes ou aux cellules pour empêcher l'infection par les micro-organismes. On peut également administrer les lectines pour traiter des infections vaginales transmises sexuellement. L'invention concerne également un dispositif destiné à être placé dans le dôme vaginal, comprenant un anneau entourant le col de l'utérus ainsi qu'une membrane recouvrant l'ouverture centrale de l'anneau afin d'empêcher le contact direct de l'éjaculat avec les tissus cervicaux. Ce dispositif est imprégné ou revêtu de lectines qu'il libère dans le vagin pendant une certaine période.

Title: System and method for detecting mass addressing events
Inventor: MINTZ DONALD JAY
IPC: H04M3/36
Filed: 1998-02-04
Abstract: A system and method for detecting mass addressing events comprising a first register, a second register, a first counter, and a second counter is disclosed. Potential mass addressing events are detected by comparing a most recently selected address to the contents of the first register and incrementing the first counter if they are equal, or loading the most recently selected address into the first register and initializing the first counter if they are unequal. If the first counter's count reaches a first count threshold, the contents of the first register are compared to the contents of the second register and the second counter is incremented if they are equal, or, if they are unequal, the contents of the first register are loaded into the second register and the second counter is initialized. If the second counter's count reaches a second count threshold, an alarm is issued. In an alternative preferred embodiment, the first and second registers and the first and second counters are periodically reset to reduce false mass addressing event alarms.

Abstract: A system for coding of digital video images such as bi-directionally predicted video object planes (B-VOPs) (420), in particular, where the B-VOP and/or a reference image .(400,440) used to code the B-VOP is interlaced coded. For a B-VOP macroblock (420) which is co-sited with a field predicted macroblock of a future anchor picture (440), direct mode prediction is made by calculating four field motion vectors (MV f,toP, MV f,bot, MV b,top, MV b,bot) , then generating the prediction macroblock. The four field motion vectors and their reference fields are determined from (1) an offset term (MV D) of the current macroblock' s coding vector, (2) the two future anchor picture field motion vectors (MV top, MV bot), (3) the reference field (405,410) used by the two field motion vectors of the co-sited future anchor macroblock, and (4) the temporal spacing (TR b,top, TR b,bot, TR D,top. TR D,bot), in field periods, between the current B-VOP fields and the anchor fields. Additionally, a coding mode decision process for the current MB selects a forward, backward, or average field coding mode according to a minimum sum of absolute differences (SAD) error which is obtained over the top (430) and bottom (425) fields of the current MB (420).

Abstract: A distribution reference signal is described for use in synchronizing data transmission. The distribution reference signal includes a digital symbol pulse train having a rate much higher than the actual reference frequency represented. A fixed group of symbols is used to identify a low frequency signal event or reference pulse. A second group of sequence symbols indicates continuous phase information. The symbols used to identify the reference pulse are significantly different from the other phase information facilitating identification of the reference pulse. By encoding a known sequence of symbols to represent the phase information in the reference signal, an increased amount of frequency information can be propagated as compared with a single pulse aiding the detection and correction of signalling errors as the errors will break the expected symbol sequence. A system can then identify and correct or choose to ignore the errors based on the effect the errors will have on the system performance.
