IPC: G01V1/00
Filed: 2003-02-27
Abstract: Méthode et dispositif de prospection sismique par émission simultanée par plusieurs vibrateurs de signaux sismiques obtenus en modulant en phase un signal périodique dont l'amplitude et les dérivées par rapport au temps de l'amplitude s'annulent a u début et à la fin de chaque période, par des séquences pseudo aléatoires. On capte par des récepteurs couplés avec la formation, les signaux sismiques  renvoyés par les discontinuités du sous-sol en réponse aux signaux périodiques émis et on  les enregistre dans un système d'acquisition et d'enregistrement. Les signaux sismiques émi s sont formés soit à partir de séquences élémentaires d'une durée au moins égale au  produit du nombre de sources sismiques vibrant simultanément par le temps d'écoute, soi t à partir de cette séquence élémentaire augmentée, avant et après, de parties d'une durée  au moins égale au temps d'écoute, la réception et l'enregistrement des signaux renvoy és par les discontinuités du sous-sol en réponse aux signaux émis, et le traitement des  signaux enregistrés. La contribution respective de chacune des différentes sources sismiques est isolée en corrélant les signaux reçus et enregistrés soit par des signaux construits à partir de la dite séquence élémentaire, augmentée, avant et après, de parties d'une  durée au moins égale au tempsd'écoute, obtenues par permutation circulaire, soit de la dite  séquence  élémentaire. Applications à la prospection sismique ou la surveillance sismique de gisements, par exemple.

Abstract: A stroller having a novel frame geometry that provides a more direct structural tie between the front and the rear wheels. The two rear legs (bottom members) of the frame are disposed at a relatively small angle to the horizontal and remain close to that shallow angle as the stroller is folded, with all four wheels on the ground. The rear leg assembly is pivotally linked to the front leg assembly, so that the front leg assembly collapses onto the rear leg assembly when the stroller is folded. The front legs and the rear legs preferably have a similar profile so that they generally nest when folded. The front legs and the rear legs preferably have oval or oblong cross-sections, which enhances their vertical load strength.

Title: Floating conductor pad for antenna performance stabilization and noise reduction
Inventor: QI YIHONG
IPC: H01Q1/52
Filed: 2003-07-24
Abstract: An antenna in a wireless mobile communication device is often sensitive to its operating environment, such that variations in other device components typically affect performance of the antenna. A floating conductor pad comprising a patch of conductive material is configured to be positioned adjacent the antenna to couple to the antenna. The floating conductor pad thereby has a dominant effect on the antenna in the operating environment. This reduces the effects of variations in the other device components on the antenna. Effective selection of the dimensions and location of the floating conductor pad can also cancel noise generated by the other device components from de-sensitizing communications circuitry in a wireless mobile communication device.

Title: Structure of an anti-burglar screw bolt
Inventor: CHANG SHIH-I
IPC: F16B39/24
Filed: 2003-08-28
Abstract: An anti-burglar screw bolt includes a bolt, first and second pads, and a nut. The bolt head is hexagonal, and consists of six sections of same shape each having a slope on a lower side and abutting a lower end of adjacent section at a higher end. Each of the pads has slopes like those of the bolt head; each of the pads has radial pointed bars formed on other side, and gaps on lateral side for a tool to engage, which is especially designed for undoing the bolt. The nut is hexagonal, and has slopes like those of the bolt head. The bolt is passed through the first pad, workpieces, and the second pad in sequence, and is screwed into the nut to fasten the workpieces together with the radial pointed bars being driven into surfaces of the workpieces. The bolt combination can't become loose because the pads abut both the bolt and the nut to hinder reverse rotation of the bolt that will undo the bolt.
