摘要： A method and apparatus for self-tuning a piano that optically senses the vibration of all the piano's strings independently and simultaneously. Interference caused by alternating-current ambient lighting is removed by modulating the string's signal onto a high-frequency carrier wave, filtering out the low-frequency ambient light interference wave, then demodulating and removing the carrier to render the original signal. Digital pitch, diagnostic, and control parameter information is interchanged between a supervisory master microcontroller and the autonomous string sustainer circuits via a master-slave serial bus connected through a single, common cable. PWM duty cycles for the string tuning coils are handled autonomously by an FPGA or a decoder network, which also communicates with the master control circuit. Pulse-width modulated control signals are filtered to a DC control voltage and combined with a drive oscillator signal using a summing amplifier to eliminate audible noise due to magnetostriction in the tuning coils.

摘要： A drive mechanism of a lifting rail for a musical instrument including a lifting rail, the drive mechanism including: a connection member connected to the lifting rail; and a movement-force giving mechanism configured to move the lifting rail via the connection member, wherein the lifting rail includes: a hollow portion opening at one end; and a through-hole formed through an upright wall portion of the lifting rail, wherein the connection member includes: an insertion member having an attachment hole corresponding to the through-hole; a fixing member for connecting the lifting rail and the connection member; and a contact portion configured to come into contact with the one end of the lifting rail when the insertion member is inserted in the hollow portion by a prescribed distance so as to prevent the insertion member from being further inserted in the hollow portion, thereby positioning the attachment hole relative to the through-hole.

摘要： A camera assembly for filming the hands of a musician playing a finger board instrument includes a guiding device mounted to the finger board instrument. A stage movably engages the guiding device. A camera is mounted on the stage for filming the hands of the fingerboard user as the hands travel along the finger board. A driving device, such as a linear motor, is connected to the stage for moving the stage along the guiding device. A means for controlling the camera is also provided, either manually from a remote location or by visual tracking. A sensor senses the velocity and position of the stage and outputs a detection signal to the control means. The control means transmits command signals to the driving device for actuating movement of the camera along the guiding device.
摘要翻译：用于拍摄播放指板式乐器的音乐家的手的相机组件包括安装到指板乐器的引导装置。台架可移动地接合引导装置。当手指沿着指板行进时，相机安装在舞台上用于拍摄指板用户的手。诸如线性电动机的驱动装置连接到用于沿着引导装置移动工作台的工作台。还可以通过手动从远程位置或通过视觉跟踪来提供用于控制摄像机的装置。传感器感测台的速度和位置，并向控制装置输出检测信号。控制装置将命令信号发送到驱动装置，以驱动照相机沿引导装置的移动。

摘要： The inventions are a device and method specifically designed to separate the pinblock (or wrestplank) from the piano case in certain grand pianos wherein the pinblock is installed with shims, wood dowels and glue along three edges so as to make the pinblock an integral part of the case. With the device and method this as accomplished quickly, easily and cleanly along the glue line by applying a controlled force between the two parts and without risk of damage to the finished parts of the piano case.
摘要翻译：本发明是一种专门设计用于在特定的三角钢琴中将钢钉（或摔跤板）与钢琴盒分开的装置和方法，其中针脚沿着三个边缘安装有垫片，木榫钉和胶水，以使针脚成为案子。通过在两个部件之间施加受控的力并且不会损坏钢琴机箱的成品部件的风险，通过这种装置和方法可以快速，简便地沿着胶合线完成。
