Abstract: Technical solutions include systems and methods for multi-access-point (AP) coordination of coordinated beamforming (CBF) for nulling of mutual interferences. A first AP can be configured to identify a second AP that is capable of participating in coordinated beamforming (CBF), select one or more candidate stations of the first AP and identify capabilities of at least one of the first AP or the one or more candidate stations. The first AP can be configured to determine one or more stations of the one or more candidate stations to participate in CBF based at least on the capabilities and perform a sequence with the second AP to exchange, between the first AP and the second AP, a set of stations of the first AP and the second AP to participate in CBF.

Abstract: The present disclosure is in the field of surgical instrument, in particular drills used by surgeons and or dentist, or surgical robots. It is known that a motor generates a torque during rotating accelerations and decelerations. Accelerations and sharp brakes from powerful motors also generate torques to be countered by the surgeon wrist, or the robot chassis. In order to solve this problem, there is proposed a surgical power motor. The motor is made of two rotating parts, rotating in opposed directions, and further includes an inverter to link one rotating part with the other rotating part, each rotating part producing the similar acceleration torque and at least one being powered either by an electric or pneumatic source.

Abstract: Example implementations are directed to a method and system for collision avoidance for an aircraft traversing a flight path. The method and system described herein provides an architecture to address the full gamut of complexity that arises when dealing with possible conflicts during aircraft flight. The collision avoidance method and system disclosed herein first receives multiple streams of potential conflict information that not only considers direct obstacles on the flight path of the aircraft, but also considers contextual obstacles that are within a perimeter of the flight path. Once the possible objects are considered, a plurality of alternate flight paths are calculated and the alternate flight path with an acceptable miss distance with a possible obstacle (and minimized deviation from the original flight path) is selected and the aircraft traversing the flight path deviates from the original flight path to the alternate flight path to avoid the collision(s).
