Abstract: The present disclosure discloses an acoustic device and a method for determining a transfer function thereof. The acoustic device includes a sound production unit, a first detector, a processor, and a fixing structure. The sound production unit is configured to generate a first sound signal based on a noise reduction control signal. The first detector is configured to obtain a first residual signal including a residual noise signal formed by superposition of an environmental noise and the first sound signal at a location of the first detector. The processor is configured to estimate a second residual signal at a target spatial location that is closer to the ear canal than the first detector, and update the noise reduction control signal based on the second residual signal. The fixing structure is configured to place the acoustic device at a location near a user's ear but not blocking the ear canal.

Abstract: The present invention provides a new class of non-immunosupressive FK506 analogs which are FKBP-selective, small-molecule BMP agonists with modest potency therepeutics for tissue repair and regeneration. Also disclosed herein are methods for making and use of these compounds.

Abstract: A cutter head includes: a support platform; a double curved surface member mounted on the support platform and having a first curved surface and a second curved surface; a cutter wheel support member and a roller wheel support member moveably mounted on the support platform, respectively; a cutter wheel and a roller wheel mounted on the cutter wheel support member and the roller wheel support member, respectively; a first transmission mechanism mounted on the support platform, configured to be mated with the first curved surface, and connected to the cutter wheel support member, so as to transmit a movement of the double curved surface member to the cutter wheel; and a second transmission mechanism mounted on the support platform, configured to be mated with the second curved surface, and connected to the roller wheel support member, so as to transmit a movement of the double curved surface member to the roller wheel.

Abstract: A substrate delivery device and a delivery method thereof are described for improving the substrate delivery efficiency, reducing abrasion in substrate delivery, and improving manufacturing efficiency of a display panel. The substrate delivery device comprises a reciprocating aligning mechanism and a screen pickup mechanism. The reciprocating aligning mechanism has a bearing platform carrying the substrate, and a first driving mechanism driving the bearing platform to move so as to bring the carried substrate to a preset position. The screen pickup mechanism has a pickup arm picking up a substrate on the reciprocating aligning mechanism, and a second driving mechanism driving the pickup arm to move. The pickup arm is located in a direction perpendicular to the substrate on the reciprocating aligning mechanism. When the reciprocating aligning mechanism moves to the preset position, the second driving mechanism drives the pickup arm to pick up the substrate on the reciprocating aligning mechanism.
