摘要： Various embodiments of the present invention generally relate to prosthetic partial finger designs that can mimic the last two joints of the finger. Some embodiments include a proximal phalange, a distal phalange coupled to the proximal phalange, and a knuckle track (e.g., formed in an arc). The knuckle track can be moveably coupled to the proximal phalange an may include multiple teeth formed on which the proximal phalange slides along. A ratcheting mechanism can contact the multiple teeth to allow sliding in only a first direction while the ratcheting mechanism is engaged. Some embodiments include a release mechanism (e.g., a button) configured to disengage the ratcheting mechanism from the multiple teeth to allow the distal phalange to slide in a second direction. In some embodiments, the device may include a spring-back capability that automatically extends the finger after reaching full finger flexion, enabling one-handed use.

摘要： The present disclosure relates optical imaging devices and methods useful in biological and medical imaging applications. In one embodiment, an optical imaging device includes a flexible lightguide having a first end and a second end, the output of the source of pulsed infrared radiation being optically coupled to the first end of the flexible lightguide; a lens assembly attached to and optically coupled to the second end of the flexible lightguide, the lens assembly comprising a variable-focus lens element, the a variable-focus lens element having a tunable focal length; and a photodetector coupled to the flexible lightguide to detect radiation propagating from the second end toward the first end of the flexible lightguide. The optical imaging devices and methods can be used in both confocal and multi-photon techniques.

摘要： Systems and methods for postural control of a multi-function prosthesis are provided. Various embodiments provide for a postural controller that use EMG signals to drive a point in a posture space and outputs continuously varying joint angles for a powered prosthetic hand. The postural controller can include an EMG signal processing unit to receive signals from electrodes for processing (e.g., band pass filtering, rectification, root mean square averaging, dynamic tuning, etc.). The processed EMG signals can then be combined or converted to produce a point in the postural control domain. The PC domain map defines the posture that corresponds to each PC cursor coordinate. This map can have limitless possible postures and limitless possible positions of the postures. The Joint Angle Transform converts the PC cursor coordinate into the joint angle array which is sent to the prosthetic hand thereby creating more natural movements.

摘要翻译： 提供了一种用于多功能假体的姿势控制的系统和方法。 各种实施例提供了一种姿势控制器，其使用EMG信号来驱动姿势空间中的点并输出用于动力假肢手的连续变化的关节角度。 姿势控制器可以包括用于接收来自用于处理的电极的信号（例如，带通滤波，整流，均方根平均，动态调谐等）的EMG信号处理单元。 然后可以组合或转换经处理的EMG信号以在姿势控制域中产生点。 PC域映射定义对应于每个PC光标坐标的姿势。 这张地图可以有无限可能的姿势和姿势的无限可能位置。 联合角度变换将PC光标坐标转换成关节角度阵列，该阵列发送到假肢手，从而产生更自然的运动。
