US Classification:

280602, 280 141, 310317, 310326

Abstract:

A recreational board such as a snowboard incorporates strain transducers to damp a plate resonance of the board. The strain transducers are preferably located around a peripheral region to capture strain energy affecting control edges, for example steering control edges at the front and/or rear of the board. Electrical energy from the transducers is shunted to damp a targeted resonance. In a preferred embodiment the strain transducers cover a region of the snowboard adjacent one surface and extending along the forward periphery, preferably at both inside and outside edges, and are shunted with a resonant shunt tuned to a torsional or torsion-like mode of the board that is excited during steering maneuvers. The transducers may be fabricated as preassembled sheets or may be formed in the snowboard during the assembly process using sheets of piezoceramic material, or using piezo fiber or other composite constructions. The strain material may be positioned to preferentially shift or damp one resonance mode, and/or it may be arranged to exert a directional effect or anisotropic control authority.

International Classification:

US Classification:

473521, 473546, 310317, 310326

Abstract:

A golf club includes an electroactive assembly attached to the club and electrically tuned to capture energy from one or more vibrational modes with high efficiency. More generally, a sports implement includes an electroactive element, such as a piezoceramic sheet attached to the implement, and a circuit attached to the electroactive element. The circuit may be a shunt, or may include processing such as amplification and phase control to apply a driving signal which may compensate for strain sensed in the implement, or may simply alter the stiffness to affect performance. The electroactive element is located in a region of high strain to apply damping, and may include plural subassemblies mounted to capture energy in different planes, or to capture an asymmetric strain distribution while maintaining structural symmetry. In a ski the element captures between about one and five percent of the strain energy of the ski. The region of high strain may be found by modeling mechanics of the sports implement, or may be located by empirically mapping the strain distribution which occurs during use of the implement.

US Classification:

Abstract:

A baseball bat includes an electroactive assembly attached near the handle and electrically tuned to capture energy from several modes with high efficiency. More generally, a sports implement includes an electroactive element, such as a piezoceramic sheet attached to the implement, and a circuit attached to the electroactive element. The circuit may be a shunt, or may include processing such as amplification and phase control to apply a driving signal which may compensate for strain sensed in the implement, or may simply alter the stiffness to affect performance. In a ski, the electroactive element is located near to the root in a region of high strain to apply damping, and the element captures between about one and five percent of the strain energy of the ski. The region of high strain may be found by modeling mechanics of the sports implement, or may be located by empirically mapping the strain distribution which occurs during use of the implement. In other embodiments, the electroactive elements may remove resonances, adapt performance to different situations, or enhance handling or comfort of the implement.

International Classification:

A61B 3/113

A61B 5/00

Abstract:

A method of testing a subject for impairment includes presenting an object to the subject and measuring gaze positions of the subject. The method further includes generating, using the measured gaze positions, a plurality of values of a gaze metric. The method further includes generating a cognition metric for the subject based on one or more of the group consisting of: a measure of a skewness of a distribution of the plurality of values of the gaze metric; and a measure of kurtosis of the distribution of the plurality of values of the gaze metric. The method further includes determining whether the cognition metric is indicative of cognitive impairment; and generating a report, based at least in part on the determination of whether the cognition metric is indicative of cognitive impairment, indicating the presence or absence of cognitive impairment.
