Abstract: A Convolutional Neural Network (CNN) based-signal processing includes receiving of an encrypted output from a first layer of a multi-layer CNN data. The received encrypted output is subsequently decrypted to form a decrypted input to a second layer of the multi-layer CNN data. A convolution of the decrypted input with a corresponding decrypted weight may generate a second layer output, which may be encrypted and used as an encrypted input to a third layer of the multi-layer CNN data.

Abstract: Techniques including receiving a distorted image from a camera disposed about a vehicle, detecting, in the distorted image, corner points associated with a target object, mapping the corner points to a distortion corrected domain based on one or more camera parameters, mapping the corner points and lines between the corner points back to a distorted domain based on the camera parameters, interpolating one or more intermediate points to generate lines between the corner points in the distortion corrected domain mapping the corner points and the lines between the corner points back to a distorted domain based on the camera parameters, and adjusting a direction of travel of the vehicle based on the located target object.

Abstract: A die for extruding a pipe includes a die head having an inlet for receiving and a bore for mixing an extrudate, a punch placed axially inside the die head, and a die cavity mounted at an outlet thereof. An outer surface of the die cavity includes flat surfaces at points of contact of a first adjustment structure which includes a plurality of flat end bolts perpendicular to each other positioned around the die cavity for adjusting position of the die cavity. The die further includes an extended orifice shaped as a thin walled tube formed around the orifice, and a second adjustment structure located at a tip of the orifice to distort the orifice for maintaining uniform flow of extrudate, and a plurality of segments are located around the orifice to uniformly distribute the load of the second adjustment structure on to the outer circumference of the orifice.

Abstract: A threaded pipe (11) and coupler (5) made of polyvinyl chloride, the coupler (5) comprising two coupling ends having inner square-shaped threading (3, 14), each receiving a pipe end (4, 11) having an outer square-shaped threading, a sealing ring (2, 13) being provided between each coupling end of an inner surface of the coupler (5) and an outer surface of the corresponding pipe end (4, 11); a groove (10), being formed on the inner surface of the coupler (5), and co-operating with a part of the outer surface of the pipe end after the threading, when the pipe (11) is threadingly coupled in the coupler (5), to form a tangential hole (42) between the outer surface of the pipe (11) and the inner surface of the coupler (5) with the groove made on the outer surface of the coupler aligning with a groove of first pipe, wherein a wire lock (41) is inserted in the tangential hole (42) to lock the coupling of the coupler (5) with the end of the pipe (11).

Abstract: A Polyvinyl Chloride Threaded Pipe Joint System With Coupler & Wire Locking device comprising two pipe joining components, two sealing rings, including a wire lock, the said wire lock is component being inserted into the groove which locks the coupling with the one end of the pipe joint, the said coupling joining the both the ends using the threads, the said threads are made in the form of square type threads and the said sealing rings are fixed to the both the ends of the pipes and coupler.
