Abstract: A double-bar violin family without sound post, including a resonance box, with a front plate, back plate and sidewalls, wherein: two upper bars are parallel on the front plate inner wall; two lower bars are parallel on the back plate inner wall; an upper cross groove sits on the front plate inner wall, and forms an upper cross sound tunnel on the front plate inner wall; a lower cross groove sits on the back plate inner wall, and the lower cross groove forms a lower cross sound tunnel on the back plate inner wall.

Abstract: A method for measuring angular velocity and angular acceleration based on monocular vision. Firstly, a movement sequence image of a feature mark fixed on a working table of a rotary motion generating device is acquired via an acquisition and imaging device. Secondly, a region of interest on the movement sequence image of the feature mark under different shooting distances and rotating conditions is determined by cyclic matching between a set of circular templates and the movement sequence image of the feature mark. Then, a sub-pixel of feature line edges in the region of interest is extracted using a line segment detection method, and only the feature line edges in a motion direction are retained through a constraint of the number of edge points. Finally, the angular velocity and angular acceleration are calculated by using the extracted feature line edges in the motion direction.

The systems and methods include forming a stitch on the target device, adjusting a thread coupled to a needle used to form the stitch so that the thread is clear of (e.g., does not interfere with) a path of the needle, and applying a targeted tension to the thread to tension the stitch on the target device. The suturing process can also include providing different targeted tensions during formation of the stitch. The suturing process can also include providing different targeted tensions at different stages of the formation of the stitch to aid in forming the stitch, to clear the needle path of the thread, and/or to hold the stitch in place in preparation for the next stitch.

Abstract: A preclean process may be omitted from a eutectic bonding sequence. To remove oxide from one or more surfaces of a device wafer of a micro-electromechanical-system (MEMS) structure, a duration of an acid-based etch process in the eutectic bonding sequence may be increased relative to the duration of the acid-based etch process when the preclean process is performed. The increased duration of the acid-based etch process enables the acid-based etch process to remove the oxide from the one or more surfaces of the device wafer without the use of a preceding preclean process. This reduces the complexity and cycle time of the eutectic bonding sequence, reduces the risk of stiction between suspended mechanical components of the MEMS structure, and/or reduces the likelihood that the MEMS structure may be rendered defective or inoperable during manufacturing, which increases process yield.
