Inventor: DONG JIYI
IPC: B23K20/12
Filed: 2018-12-13
Abstract: A friction stir welding device capable of realizing weld thickening, the device comprising a zero-tilt-angle welding module (3), a constant pressure control module (1) and a stirring tool module (2). By means of the zero-tilt-angle welding module (3), a center line of a stirring tool always remains parallel to the normal direction of a surface of a workpiece to be welded during welding. The constant pressure control module (1) keeps an axial pressure of the stirring tool on the workpiece constant during welding. The stirring tool module (2) comprises a shaft shoulder (5), a stirring pin (6) and a clamping end (4). A method for welding using the friction stir welding device is further provided. By means of zero-tilt-angle welding, the requirements for a welding apparatus during two-dimensional and three-dimensional welding of welds are reduced, thereby omitting a tilt angle adjustment mechanism and expanding the application range of friction stir welding. Material addition can be implemented in a weld area without filling with an external material, thereby solving the problem of weld thinning and improving the fatigue performance of the weld area.

Title: An earpiece and a method for detecting physiological information
Inventor: WONG MING YIP WALLACE
IPC: H04R1/10
Filed: 2019-05-05
Abstract: An earpiece which comprises a sensor for detecting light which has travelled through the tissue of an ear canal. The sensor is held in a cradle to reduce the field-of-view. The reduced field-of-view reduce the possibility of light reaching the sensor in a tangential angle. Therefore, ambient light and light from a emitter reaching the sensor is reduced. This improves the likelihood that the readings of the sensor has a greater portion from light that has travelled through the tissue of the ear canal than not. Furthermore, the earpiece is tailor-made to fit to the ear of a specific user. As the ear is not a symmetrical part of the body, the location of the earpiece is virtually repeatable each time the user wears the earpiece. This allows breaks in continual wearing of the earpiece while allowing the earpiece to monitor light which has travelled through the tissue of an ear canal in virtually the same position. Furthermore, the earpiece is preferably made of a nozzle containing the sensor, and an emitter, all encapsulated into a hard material which allows light to pass through. Using only one material reduced internal reflection when light travels from the emitter to the surface of the earpiece, thereby reducing signal noise and background. Typically, the earpiece also comprises a speaker such that the earpiece is able to function as an earphone.

Abstract: Disclosed are a tension-type cavity (1) and a connected cavity, and a seat and bedding. The tension-type cavity (1) comprises a liner (1-1), a tension layer (1-2) and a support (1-3), wherein the tension layer (1-2) and the support (1-3) constitute a pull-support structure; the liner (1-1) is disposed inside the pull-support structure; and the tension layer (1-2) is in flexible contact with the liner (1-1) to form a working face (1-5), and the working face (1-5) restricts bulging of the liner (1-1), thereby realizing external flexible shaping of the liner (1-1). The liner (1-1) has a simplified construction, and is not subjected to stress concentration, such that the safety and the service life of the liner are greatly improved; and the liner (1-1) uses an upper portion or front portion heating manner, thereby realizing instantaneous heating and temperature control. The tension-type cavity (1) is in communication with an external flexible bag to constitute the connected cavity, and the seat and the bedding comprise the connected cavity. The connected cavity structure realizes free migration of an internal liquid, greatly reduces the pressure in the liner (1-1), buffers the impact of an external force on the liner (1-1), and facilitates the protection of the liner (1-1). Moreover, a water level difference in the connected cavity counteracts the liner (1-1) to generate uniform and gentle hydroelasticity, thereby improving the comfort of sitting and lying.
