IPC: G01S11/02
Filed: 2016-10-24
Abstract: In a general aspect, motion of an object is detected based on wireless signals. In some aspects, wireless signals based on a repeated wireless transmission are received at a wireless sensor device in a space. The received wireless signals are analyzed, by operation of a processor, to detect movement of an object in the space. The analysis includes determining complex values representing the relative phases and amplitudes of respective frequency components of each of the received wireless signals, and detecting movement of an object in the space based on a change in the complex values.

Title: Coulisse a activite variable et activee par pression selective
Inventor: JONES KEVIN DEWAYNE
IPC: E21B31/107
Filed: 2017-02-27
Abstract: La présente invention concerne un outil de battage utilisé pour déloger une colonne tubulaire ou un ensemble de fond de trou bloqué dans un puits de forage souterrain. Des colonnes tubulaires avec lesquelles l'outil peut être utilisé peuvent être formées d'une tige de forage, une tige articulée ou un tube spiralé. Un élément d'entonnoir est placé dans le sous-sol dans une colonne tubulaire, ou en tant que partie de celle-ci. Une bille déformable peut être installée dans l'élément d'entonnoir pour empêcher un fluide de passer dans la colonne tubulaire. Une pression hydraulique peut s'accumuler dans la colonne tubulaire jusqu'à ce qu'elle dépasse la pression que la bille peut supporter. Cela conduit la bille à se déformer et à être expulsée à travers l'élément d'entonnoir. Sans bille pour bloquer son écoulement, le fluide est rapidement libéré à travers l'élément d'entonnoir. La libération rapide de fluide cause un battage ou une secousse puissant de la colonne tubulaire ou de l'ensemble de fond de trou.

Abstract: An illumination device, system and method are provided herein for emulating sunlight along a daytime or nighttime locus. Sunlight is emulated depending on the path length of the sun relative to a structure containing the illumination device and system. One or more illumination devices can be grouped together and perform the sunlight emulation along the locus by producing different color temperatures throughout the day by all illumination devices within that group producing the same color temperature changes throughout the day. Moreover, a particular advantage of the preferred embodiments is the ability to manually change at any time the emulated natural sunlight output from the one or more groups of illumination devices and advantageously change the color output more so at certain times than at other times by simply actuating a trigger on a dimmer associated with a virtual or physical keypad.
