Abstract: A swing torque sensing and transmitting device, flexibly mounted between the grip of a torque tool and the drive head of a bolt or nut, includes a sensing shaft, a torque sensing unit, a battery cover plate, two outer housings, a circuit board module and a battery module. A battery cover plate holds the battery module inside a housing. The circuit board module is set in another housing. The device is swinging in the process of tightening or un-tightening the threaded fastener, by sensing the deformation sensing signal caused by the body bending due to pushing or pulling, which is amplified by the circuit board module, and continuously calculates the applied torque and angular movement of the device, and when the target torque or angle displacement is reached, an audible and visual warning is given while the result is displayed, recorded or uploaded at the same time.

Abstract: A bifurcated stent-graft and stent-graft delivery system for placement and delivery into an anatomical structure of the body, such as the superior vena cava, are disclosed. The stent-graft includes a first, second and third wire portions that provide strength, flexibility, and resilience. The wire portions are incorporated and joined by a graft fabric that forms a flexible joint that provides increased flexibility. The stent-graft can also include an aperture to allow for unobstructed blood flow from branched or tributary blood vessels such as the azygos vein.

Abstract: A retractable mobile device power module comprises of a plug to power outlet, a retractable power cord, an adapter, and a retractor. With this design, power supply for mobile devices can be compact and low profile. Besides providing power, this design can be used for data transmission as well.
