Title: Collison detection during short feedback procedures in wireless networks
Inventor: PATRICE NEZOU
IPC: H04W84/12
Filed: 2019-06-19
Abstract: A random access mechanism for short feedback procedure with collision detection using null data packets, NDP, and NDP feedback report poll, NFRP. A random-access NFRP trigger frame is provided that defines RU tone sets accessible through contention. Any station randomly selects one of the eligible RU tone sets and then randomly selects one of the tone groups forming the selected RU tone set. The station sends its NDP feedback report response using the selected tone group. The AP may determine the the collided RU tone sets where two or more different tone groups are used by responding stations, the unused RU tone sets and used RU tone sets where no collision is detected. An subsequent UL MU transmission is scheduled that involves the stations of the RU tone sets detected as used without collision. Unused RUs in the UL MU transmission are avoided and risks of collisions are reduced by half or more, dependant on the number of tone groups in a tone set. Tone groups may correspond to Feedback Status values or Set Indexes. Also discloses are methods of determining that random access to a RU tone set is provided.

Abstract: A magnetic encoder 1 comprises: an encoder element 2 with one or more magnetized elements that, in use, are fixed to a backing member, the elements together defining at least two tracks 3, 4 of encoder regions and each region comprises an alternating pattern of North and South magnetic poles. At least one sensor 5, 6 is fixed in a location relative to which the location of the magnetized elements 2 of the tracks 3, 4 are to be determined. The magnetic encoder 1 includes at least one feature 10 that simultaneously provides a location suitable for a mechanical fixing of the magnetized elements to a moving part and contributes to a sensed magnetic field periodic variation along a first track which at least partially cancels out a sensed magnetic field periodic variation in another track. The at least one feature 10 may be cutaway portions of the outer track magnetic poles on their outer edge to form four equidistant flat keying portions around a disk. This feature may provide a magnetic field pattern which may be processed to reduce a fourth harmonic interference in a sensed encoder magnetic field pattern signal. The at least one feature 10 may be one or more holes within, or at the edge of an encoder element, or interpole region of a multiple track linear or rotary encoder. The encoder elements may have an inwards tapered outer edge with concentric tracks on a disk support.

Title: Rotation variant object detection in deep learning
Inventor: BINGCAI ZHANG
IPC: G06T5/00
Filed: 2018-11-07
Abstract: System and method for detecting objects in geospatial images, 3D point clouds and Digital Surface Models (DSMs). Deep Convolution Neural Networks (DCN Ns) are trained using positive and negative training examples. Using a rotation pattern match of only positive examples reduces the number of negative examples required. In DCN Ns softmax probability is variant of rotation angles. When rotation angle is coincident with object orientation, softmax probability has maximum value. During training, positive examples are rotated so that their orientation angles are zero. During detection, test images are rotated through different angles. At each angle, softmax probability is computed. A final object detection is based on maximum softmax probability as well as a pattern match between softmax probability patterns of al l positive examples and the softmax probability pattern of a target object at different rotation angles. The object orientation is determined at the rotation angle when softmax probability has maximum value.

Title: Form Wound Motor for Electrical Submersible Pumps
Inventor: HASSAN MANSIR
IPC: H02K15/04
Filed: 2021-03-26
Abstract: The disclosed new winding arrangement was developed to enhance the manufacturability of stators with large length-to-diameter ratio and small aperture diameters, such as those designed and manufactured for downhole pumping applications. The rectangular ‘hairpin’ conductors are pre-formed to a specific shape, nested together, and inserted into the stator slots. Once the conductors are inserted, additional bending and joining operations are required to complete the coils and phases. These operations can be either fully automatic or semi-automatic. The structure of the winding allows insertion of phase and phase-to-phase insulation after the joining operation is completed, thus reducing the risk of damage to the insulation system during the joining process. Due to its ability to nest by design, the pre-formed winding results in very short end-turns compared to a conventional winding.
