An exercise device independent, variable display rate visual exercise system uses a sensor to sense repetitive movements or other physical functions of the user. A computing device-readable medium containing computing device executable instructions which, when run on a computing device, cause the computing device to receive a user-exercise signal related to a user-exercise level, determine a modified frame-display time for a visual-image stream in response to the user-exercise signal, and provide the modified frame-display time to a visual-image stream player. Determining the modified frame-display time may include instructions that determine a user-exercise level in response to the user-exercise signal, receive a camera-mount speed and a native frame-display time for a recorded visual-image stream, correlate the camera-mount speed and the user-exercise level, and modify the native frame-display time in response to the correlation to produce the modified frame-display time. These instructions permit the visual-image stream player when playing the visual-image stream to dynamically change the frame-display time as a function of the user-exercise level.

There is provided a method and system for generating a timing vector for use in a user authentication system based on keystroke dynamics. The timing cues are presented to a user, who then types a password according to the timing cues. Then, a timing vector is generated based on the keystrokes of the typed password. The auditory and visual cues may include a repetitive sound played in a certain fixed tempo and a repetitive movement shown in a certain fixed tempo, respectively. The audiovisual cue may include simultaneous sound and movement rendered in a certain fixed tempo. Further, a list of exemplary artificial rhythms, which are used as keystroke dynamics when typing a password, may be presented to the user. The artificial rhythms and timing cues help a user to type a password having more unique and consistent patterns, which results in improved identity verification accuracy.

Techniques are discussed for providing mechanisms for coding and transmitting high definition video, e.g., over low bandwidth connections. In particular, foreground-objects are identified as distinct from the background of a scene represented in a plurality of video frames received from a video source, such as a camera. In identifying foreground-objects, semantically significant and semantically insignificant movement (e.g., repetitive versus non-repetitive movement) is differentiated. Processing of the foreground-objects and background proceed at different update rates or frequencies.

An exercise system adapted to provide a truly interactive level of exercise with timed exercise intervals that are shown to be optimal in various physiological studies. An example of this invention provides the following unique features: (1) electronically controlled, continuously variable resistance in the positive stroke that responds to the user's efforts and varies the resistance according to the user's current physiological needs; (2) electronically controlled, continuously variable resistance force in the negative stroke that incrementally overcomes the positive muscle contraction and returns to the original position to complete each repetition; and (3) a sophisticated feedback control system that (a) monitors distance, time, and applied force by a user, (b) systematically controls the resistance force to complete each repetition in the specified time intervals, (c) maintains a smooth transition throughout the range of motion, and (d) virtually eliminates the variations of resistance caused by biomechanics, friction, inertia, etc. As a result, an example of the present invention provides the optimum in various types of exercise programs, including but not limited to (1) muscle building, (2) muscle toning, and (3) physical rehabilitation.

Techniques are discussed herein for providing mechanisms for coding and transmitting high definition video, e.g., over low bandwidth connections. In particular, foreground-objects are identified as distinct from the background of a scene represented by a plurality of video frames. In identifying foreground-objects, semantically significant and semantically insignificant movement (e.g., non-repetitive versus repetitive movement) is differentiated. For example, the swaying motion of a tree's leaves being minor and repetitive, can be determined to be semantically insignificant and to belong in a scene's background. Processing of the foreground-objects and background proceed at different update rates or frequencies. For example, foreground-objects can be updated 30 or 60 times per second. By contrast, a background is updated less frequently, e.g., once every 10 seconds. In some implementations, if no foreground-objects are identified, no live video is transmitted (e.g., if no motion is detected, static images are not configured to be repeatedly sent). Techniques described herein take advantage of the realization that, in the area of surveillance and wireless communications, updating video of semantically significant movement at a high frame rate is sufficient.

A vapor-dispersing device comprising a moveable piston with a porous protuberance is described that operates by the repetitive movement of the piston to intermittently dip the porous member into a volatile liquid and to expel air out through vents.

A tool for making gentle repetitive movements to the joints between a person's sacrum and ilium which allow for proper pelvic alignment when one or both have become irritated, inflamed, or malaligned, and causes significant pain. Use of the tool generates a lateral and caudal directed force on an affected ilium thereby mobilizing it back into its normal position. The tool also may be used to realign the pubic synthesis.

In a machine tool and a control apparatus thereof, a repetitive movement unit is configured so that the cutting tool performs one repetitive movement with respect to multiple relative rotations between the workpiece and the cutting tool and so that a rotation angle of the relative rotation between the workpiece and the cutting tool during relative movement at a second speed is smaller than a rotation angle of the relative rotation during relative movement at a first speed in one repetitive movement. This configuration limits degradation of machining efficiency when the cutting tool machines the workpiece by performing one repetitive movement with respect to multiple relative rotations between the workpiece and the cutting tool.
