Title: Dispositif d'interconnexion a trous traversants avec fils conducteurs isoles et barrieres pour les composants
Inventor: RENTERIA VICTOR H
IPC: H05K3/30
Filed: 1998-01-23
Granted: 2004-11-02
Abstract: Cette invention se rapporte à un dispositif servant à l'interconnexion électrique des fils conducteurs (22) de divers éléments électroniques (20) à l'intérieur d'un boîtier microminiature (24). On prévoit à cet effet un élément de base non conducteur (10) ayant plusieurs barrières (14) pour les éléments électroniques et plusieurs trous traversants (15) pour les fils conducteurs. Ces trous traversants sont généralement situés dans les régions intérieures de l'élément de base, afin de réduire au minimum les interactions de champs potentiellement néfastes ou le couplage capacitif entre les conducteurs et les bornes extérieures du boîtier. Pendant le montage du boîtier, les éléments électroniques sont placés dans des évidements (16) créés dans l'élément de base par les barrières mentionnées ci-dessus. Ces évidements et ces barrières assurent l'alignement des éléments électroniques et contribuent à maintenir la séparation électrique et l'uniformité pendant la fabrication. On connecte entre eux les fils conducteurs provenant de deux éléments ou davantage en les torsadant ensemble et en les introduisant dans l'un des trous traversants. Les fils conducteurs sont introduits dans les trous traversant, de façon à faire saillie sous la surface inférieure de l'élément de base, facilitant ainsi le soudage (50) de toutes les connexions en une seule opération. Cet agencement réduit les coûts de fabrication et de main-d'oeuvre et augmente la fiabilité des composants et du boîtier dans son ensemble.

Further, the battery case includes supports for supporting the lower surface of the battery above any leaked acid, as well as partitions that define a discrete cavity for each battery to isolate the battery from an adjacent battery that may be leaking. The battery case also includes an electrical connector mounted for two dimensional movement that facilitates completion of a blind and automatic connection of the battery case with a complementary connector.

Title: Method for filling voids with aggregate material
Inventor: STEPHENS PATRICK J
IPC: E02D3/12
Filed: 1999-08-31
Granted: 2008-07-22
Abstract: A method for filling a void using an aggregate material, such as mine tailings, the fill material being pumped from a site which is located remote from the void. A fluid, aerated material is formed by mixing the particulate solid material with finished foam. The aerated material may also include cement or another binder for applications requiring structural strength. The bubble structure which results from incorporating the foam constituent in the fill material renders this much more fluid and pumpable, thereby allowing the use of much higher solids-to-water ratios than would otherwise be possible while still being able to pump the material over significant distances. This reduces the possibly of fluidic collapse of the material in the void, and produces other advantages as well.

Title: Apparatus and method for perimodiolar cochlear implant with retro-positioning
Inventor: JOLLY CLAUDE
IPC: A61F11/00
Filed: 1998-03-10
Granted: 2005-11-08
Abstract: An implantable cochlear electrode array includes an electrode carrier, a groove within the electrode carrier, and a flexible element located in the groove. After the electrode array is implanted, the flexible element may be held in place while the electrode carrier may be partially withdrawn so that the electrode carrier pulls away from the flexible element which emerges from the groove through the surface of the electrode carrier, except where the electrode carrier and the flexible element are attached, so that the electrode carrier wraps around an inner scala tympani wall. A portion of the apical end of the electrode carrier may extend beyond the ends of the groove and the flexible element so that the apical end of the electrode carrier does not wrap around the inner scala tympani wall when the electrode carrier is partially withdrawn after insertion in the cochlea. The electrode carrier may include a perimodiolar section to be positioned next to an inner scala tympani wall of the cochlea, and an outer wall section to be positioned next to an outer scala tympani wall of t he cochlea. Theperimodiolar section may be shorter than the outer wall section to accommodate the real length difference between the inn er and outer walls of the scala tympani of a cochlea. Preferred embodiments are also directed to amethod of fabricating such a cochlear electrode array by negative casting, and to a method of implanting such a cochlear electrode array.

Granted: 2004-04-13
Abstract: A lever handle door lock keeps the lever handle horizontal and accommodates pre-manufactured doors with pre-drilled mounting holes at varying rotational orientations by providing a two piece adapter connection between the lever handle and a rose. The rose is mounted to the door via the mounting holes and includes a spring for returning the lever handle to horizontal. A first adapter piece is rotatably driven by the spring to return to a home position relative to the rose. A second adapter piece is connected to the lever handle and is adjustably connectable to the first adapter piece at different desired rotational orientations. Rotating the adjustable connection between the first and second adapter pieces changes the angle between the lever handle and the home position on the rose to bring the lever handle to horizontal regardless of the rotational orientation of the rose.

Abstract: There are provided optical fiber rod overcladding apparatus and method, and an optical fiber drawing method. In the preform rod overcladding method, a preform rod is clamped in a top chuck and leveled, and a glass tube is mounted in a bottom chuck and leveled. The preform rod is coaxially inserted into a glass tube. Then, the glass tube is preheated by the furnace and heated by the burner until the glass tube reaches a softening point. The preform rod is completely sealed in the glass tube by sucking air in a clearance between the preform rod and the glass tube by application of a negative vacuum pressure.  Thus, a preform is completed.

Title: Communication system
Inventor: OSHIMA MITSUAKI
IPC: H04N21/647
Filed: 1993-03-25
Granted: 2007-01-23
Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed by shifting the signal points to other positions in the space diagram. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into, low and high, frequency band components which are designated as a first and a second data stream respectively. Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability.
