Devices and methods for the effective clearing of artificial tubes, especially in-situ clearing of artificial tubes in a living being are covered in this disclosure. The devices and methods provide an elongated clearing member having a first end that is coupled to a driving mechanism and having a second working end that is subjected to repetitive motion for clearing blockages within the artificial tube. The elongated clearing member includes either a fixed or an adjustable element that selectively defines the portion of the elongated clearing member that is insertable within the artificial tube. The proximal end of the clearing member is releasably secured to the driving mechanism and the driving mechanisms may comprise a wide variety of repetitive motion drivers such as voice coil motors, piezoelectric actuators, pneumatic actuators, DC motors, etc. These devices/methods may comprise a free-standing console for hands-free operation or may comprise hand-held versions. The distal working end of the clearing member may comprise tips of differing functions, including an irrigation/aspiration feature.

An audio player comprises a means of dynamically sensing the rate of repetitive motion of the user, a means for storing digital music files, a means for retrieving and dynamically playing at least one of said music files at a rate approximately equal to the sensed rate of repetitive motion of the user, and a means for dynamically calculating and displaying information and/or statistics regarding at least one of the music file and the user. Such a device can play music, or other audio content with a repetitive beat, in substantial synchrony with the repetitive motion of the user. The device also allows the user to dynamically choose or change the music file playing. The device may detect, calculate, and display to the user various information.

The invention provides a redundant manipulator motion planning method which comprises the following steps that: (1) an upper computer analyzes the inverse kinematics of a manipulator on a velocity layer through quadratic optimization, the designed minimum performance index can be velocity norm, repetitive motion or kinetic energy and is bound by a velocity jacobian equation, an inequation and a joint angular velocity limit, and the angular velocity limit changes with a joint angle; (2) the quadratic optimization of step (1) is optimized into a quadratic programming problem; (3) the quadratic programming problem in step (2) is calculated by a linear variational inequation primal-dual neural network solver or a numerical method; and (4) the calculation result in step (3) is transmitted to a lower computer controller to drive the manipulator to move. The redundant manipulator motion planning method is based on the primal-dual neural network of the linear variational inequation, has global exponential convergence, does not involve matrix inversion and other complicated operations, greatly improves the calculation efficiency, and simultaneously has strong real-time performance, and can adapt to the changes to the joint angular velocity limit.

An apparatus, method, and software product are used to sense a repetitive motion, such as walking, running, or tapping. Thus, a rate of the repetitive motion is determined. A piece of music is then selected in response to the determined rate, and the piece of music is played. This piece of music has a tempo selected to match or approximate the rate of the repetitive motion, so that the repetitive motion and the music are substantially in harmony.

An ultrastiff precision sonic bearing assembly and method thereof for controlling an effective coefficient of friction between two elements in slidable contact configured along an interface under a force sufficient to maintain contact and having static friction therebetween, by inducing a repetitive motion in one of the elements parallel to the interface thereby altering the effective coefficient of friction therebetween. The bearing assembly also provides for additional and independent electronic control over the average thickness thereof and senses the force thereon to allow the bearing assembly stiffness to be altered.

This invention relates to a method of conducting search of moving picture data stream and repeating playback of a data stream section based on the caption information, which is displayed with moving pictures, and a reproduction apparatus using such method. The present method creates and stores link information between caption data and position of moving picture stream which is reproduced concurrently with the caption data; displays a part of the caption data during playback; searches for a moving picture data section, which is concurrently presented with a particular caption chosen from the displayed caption data by a viewer, based on the created link information; and repeats playback of the found moving picture data section. This method is very useful to language practice because it can repeat to play a video section containing captions that a viewer wants to listen repeatedly.

The invention provides a repetitive motion planning method for a redundant manipulator, which comprises the following steps of: 1) resolving a manipulator repetitive motion scheme on an acceleration layer by adopting quadratic model optimization through an upper computer, designing the minimum performance index as repetitive motion, and restraining by an acceleration Jacobian equation, a joint angle limit, a joint speed limit and a joint acceleration limit; 2) converting the quadratic model optimization in the step 1) into standard quadratic programming; 3) solving the standard quadratic programming in the step 2) by using a linear projection equation-based primal-dual neural-network solver or quadratic programming numerical method; and 4) transmitting a solving result in the step 3) to acontroller of a lower computer for driving the manipulator to move. The method realizes the repetitive motion of the manipulator on the acceleration layer, has good control effect on the redundant manipulator inconvenient to control, and can effectively prevent the manipulator from exceeding the limits and being physically damaged according to various joint limits.

Methods for video stabilization during movement include capturing a video stream by an imaging system of a video stabilization system. The video stream includes a plurality of image frames. As the video stream is captured, a motion sensor of the video stabilization system detects a pattern of recurring motion. Motion sensor data is generated for the sequence of image frames that characterizes the pattern of recurring motion. At least one image frame of the sequence of image frames is edited based on a comparison of the motion sensor data for the sequence of image frames to motion sensor data for a region of interest for the imaging system.

System, apparatuses, and methods can provide customized exercise sessions and customized videos corresponding to the exercise session. Recorded video content of a person performing a repetitive exercise can be obtained from multiple cameras. Metadata can identify certain decision points in the video tracks. At decision points, a decision can be made about switching to a different video track, e.g., to obtain a customized video with a specified amount of the repetitive motion.
