Abstract: A portable inspecting device includes PZT transducers and performs active sensing to measure the characteristics of bolted connections. The PZT transducers are mounted on opposing ends of spring-loaded rods and can be moved apart to accommodate a structure for testing. The springs cause the PZT transducers to push against opposing parts of the structure in a stable but temporary fashion. The device can be physically moved to inspect the status and health of multiple different bolted connections.

Abstract: The present disclosure discloses a method for image or video shooting. The method is applied to a terminal that includes a first camera, a second camera, and a third camera. The second camera is a black-and-white camera, and the first camera, the second camera, and the third camera are cameras using prime lenses. The third camera is a color camera using a tele-photo lens. The method includes determining at least one camera from the first camera, the second camera, and the third camera based on a target zoom ratio as a target camera. The method further includes capturing, by using the target camera, at least one image that includes a target scene. The method further includes obtaining an output image of the target scene based on the at least one image that includes the target scene. According to the present disclosure, an approximately 5× lossless zoom effect is achieved.

Abstract: A co-rotating self-cleaning multi-screw extruder with a speed ratio of 2.5 and an extruding method therefor are disclosed. The screw mechanism includes a center screw and peripheral screws which rotate in the same direction. The peripheral screws are each of a double threaded structure, and the center screw is of a quintuple threaded structure. The rotation speed of the peripheral screws is 2.5 times that of the center screw, and the peripheral screws are always meshed with the center screw, whereas the adjacent peripheral screws are intermittently meshed with each other. The extruding method therefor is as follows: there is a periodically open space between adjacent peripheral screws, providing the periodical and intermittent mixing action, so that material from different thread grooves is mixed with each other.

Abstract: Disclosed is a double-stator linear vernier permanent magnet (DS-LVPM) motor and method to increase the magnetic field modulation effect. The motor contains a primary, and first and second secondaries on both sides of the primary, spaced by an air gap. The motor secondary includes modulation teeth. The primary is bilaterally symmetrical, and permanent magnets (PM) are embedded in the yoke of the primary core elements. The design solves the inherent problem of flux leakage at the end of PMs for conventional VPM motors, so as to improve utilization of PMs, thereby increasing thrust density of the motors. Additionally, the motor secondaries are laminated by silicon steel sheet, which saves PM material and significantly reduces cost for linear long stroke applications. By adjusting PM structure parameters, the design can use finite element method (FEM) to calculate repeatedly to get PM structure parameters corresponding to maximum electromotive force (EMF).
