Abstract: Introduced here computer programs and associated computer-implemented techniques for generating measurements of physical structures and environments in an automated matter through analysis of data that is generated by one or more sensors included in a computing device. This can be accomplished by combining insights that are derived through analysis different types of data that are generated, computed, or otherwise obtained by a computing device. For instance, a computer program may enable or facilitate measurement of arbitrary dimensions, angles, and square footage of a physical structure based on (i) images generated by an image sensor included in the corresponding computing device and (ii) measurements generated by an inertial sensor included in the corresponding computing device.

Abstract: A golf training apparatus guides the execution of a golf shot. The apparatus comprises a first arm rotatable in a first plane about a first pivot at a first end of the first arm; a second arm coupled to the first arm and rotatable in second plane parallel to the first plane about a second pivot at a second end of the first arm and a first end of the second arm; and a gripper for coupling a golf club to the second arm, the gripper rotatable about a third pivot at a second end of the second arm such that a shaft of the club is rotatable about the third pivot in a third plane parallel to the first plane. The second arm is longer than the first arm. The apparatus can include a guide around which the first pivot is moveable, which can be a circular loop.

Abstract: The exhaust or the inlet duct of a marine gas turbine engine power plant installation comprises a porous duct, a plurality of circumferentially arranged non-porous channel members attached to and axially spaced along the porous duct, the channel members and the porous duct together defining a plurality of annular noise attenuating cells, and at least one layer of heat insulating material surrounding the channel members, the insulating material being contained with a cover and attached to the porous duct.
