This paper describes a novel interaction technique that recognizes a finger flicking gesture for power adjustment input for a sports game, such as golf swing or hitting. Our system measures speed of the finger motion and direction of the gesture by using a high-speed camera and a high frame rate image processing technique. By using this system, users can adjust power and angle intuitively. We d...

BACKGROUND To introduce the Chung's swing technique for small-incision lenticule extraction (SMILE). METHODS A total of 112 eyes of 56 patients were included in this study. Patients were divided into two groups: 52 eyes of 26 patients were treated with SMILE using a traditional method (traditional group) and 60 eyes of 30 patients were treated with SMILE using the Chung's swing technique (swi...

The purpose of this study was to compare traditional and swing blocking techniques on center of mass (COM) projectile motion and effective blocking area in nine healthy Division I female volleyball players. Two high-definition (1080 p) video cameras (60 Hz) were used to collect two-dimensional variables from two separate views. One was placed perpendicular to the plane of the net and the other ...

This paper proposes a simple but efficient technique to control 3D overhead crane. Load must track a desired path and not sway more than a reasonable range.The proposed method uses PID control for trolley to track the desired path and fuzzy control compensation to eliminate the load swing. Only the projection of swing angle is applied to design the fuzzy controller. No plant information of cran...

Swing, a popular technique in music performance, has been said to enhance the "groove" of the rhythm. Swing works by delaying the onsets of even-numbered subdivisions of each beat (e.g., 16th-note swing delays the onsets of the second and fourth 16th-note subdivisions of each quarter-note beat). The "swing magnitude" (loosely speaking, the amount of delay) is often quite small. And there has be...

The locomotor problem in bilateral disarticulation at the hip is serious because there is no natural motive power left to help swing either limb forward, and the physiological mechanism used in unilateral disarticulation is no longer available. The only motive power is pelvic and spinal in origin. To overcome this, a new “ swing door “ hinge prosthesis has been developed, which is particularly ...

Open-Door Expansile Cervical Laminoplasty Using Titanium Miniplates: Early Clinical Experiences. The author reports early clinical experiences using a special technique for cervical open-door laminoplasty in patients with cervical spondylotic myelopathy (CSM). Between June 2007 and February 2009, 20 patients with cervical myelopathy secondary to multilevel cervical spondylosis and spinal stenos...

Two high performance level restoration circuits are proposed, which outperform the existing level restoration circuits with cross-coupled PMOS, in terms of power dissipation and delay. The first configuration employs a back-bias scheme in order to eliminate the stand-by leakage caused by the low-swing input. The second one adopts a bootstrapping technique, in order to restore the low swing sign...

Many elite gymnasts perform the straight arm backward longswing on rings in competition. Since points are deducted if gymnasts possess motion on completion of the movement, the ability to successfully perform the longswing to a stationary final handstand is of great importance. Sprigings et al. (1998) found that for a longswing initiated from a still handstand the optimum performance of an inel...
