30results about How to "Less stability" patented technology

A balancing board allowing for selection of a desired degree of stability is disclosed. The balancing board has a platform and a hemispherical fulcrum slidably mounted to platform and bifurcated into a pair of pivot members. Each pivot member is independently positionable along an underside of the platform opposite of an engagement surface upon which a user positions themselves to practice balancing training techniques. When the pivot members are slid together, the balancing board is freely pivotable about any axis in the plane of the surface on which the pivot members are resting. Conversely, when the pivot members are spaced apart from each other, the balancing board resists pivoting in a direction aligned with the axis along which the pivot members are slidable.

Exercise platforms are adapted for aiding a user in performing aerobic exercises, such as step aerobics, as well as resistance and weight exercises. The embodiments of the present invention include a deformable surface, and detachable weight modules that allow a user to perform weight exercises using the weight of the device. Further, the exercise platforms of the present invention are stackable to allow for cooperative use of multiple platforms at once to perform a variety of different exercises. In some embodiments of the present invention, a platform is packaged with at least two sets of weight modules having different weights, and at least one resistance device.

At least one embodiment of the inventive technology relates to a snowboard having a lower surface that does not at any point along at least one specified portion thereof contact a horizontal surface underlying the snowboard when the snowboard is unweighted. Such portion(s) may be defined, at least in part, by one or more cambers. A rocker may be used to impart additional board performance benefits to a rider. Other embodiments may relate more specifically to the positioning of cambers relative to mount regions.

The present invention provides a method and a system for video stabilization in real time. The method comprises the steps of: estimating an optical flow from an previous image, Ii, to a current image, Ii+1; determining an Euclidean transformation, Fi, from the previous image, Ii to the current image, Ii+1, wherein the Euclidean transformation, Fi, comprises a product of rotation, Ri, and scaling, si, and translation, Ti; and transforming the current image, Ii+1, by applying the inverse of the Euclidean transformation, Fi, to the current image, Ii+1, in order to obtain stabilization. The transformation of the current image, Ii+1, is restricted by using Euclidean matrices Ai and Bi, wherein: Ai is used to store absolute frame transformation relative world frame coordinates, Ao is the identity matrix and Ai+1 is equal to AiFi−1 for i≧0 and Bi is used to store visualization window coordinate transformation.

At least one embodiment of the inventive technology relates to a snowboard having three cambers, a first of which may be disposed immediately inboard of a first tip section, a second of which may be disposed immediately inboard of a second tip section, and a third of which may be centrally disposed between tip section termina of the snowboard, and between said first and second cambers. The third camber may be part of a centrally disposed rocker.

A tool handle for holding multiple tools of different sizes during use. A wedge and body which, when placed together, creates a handle with a generally cylindrical shape and internal cavities for retaining hexagonal wrenches. A sliding wedge holds the hexagonal wrench and itself into place. A plurality of slots that allow each size tool to be indexed to the underside of the sliding member / wedge. There are two grouping arrangement of tools within the handle: a large group and a small group facing the opposite direction. The purpose for the two groups is to optimize the function of the wedge. If all of the tools were oriented in the same main slot then the smallest tools would not protrude from the end of the handle / body in a screwdriver mode to facilitate good function. Therefore the two groupings are arranged back to back to stabilize the tools laterally.

A method for producing a double-layer or triple-layer sound-absorbing panel (10) is specified, said panel consisting of a support panel (20) and at least one cover panel or coating (30, 35) of the support panel (20), the cover panel or coating (30, 35) being fixedly connected to the support panel (20). In this case, an open-pore (121) support panel is provided as the support panel (20) and the sound-absorbing panel (10) is arranged on each side (12, 13) provided with a cover panel or coating (30, 35) with a device opposing said side emitting a laser beam, the upper face (12) of said panel (10) being subjected to the laser beam, which is designed to burn away material from the cover panel or coating (30, 35) facing said laser beam over the depth in the direction of the laser beam in a plurality of holes (31). In this case, the laser beam acting on the panel (10) is designed such that the waist of the laser beam is focused on a plane parallel to the lower face of the cover panel or top layer (30, 35) such that the holes (31) are continuous through the cover panel or top layer (30, 35), and a lower hole opening / hole end (33) is produced in the support panel (20) itself so that the surroundings are connected to the open-pore support panel (20) via an air connection (121).

A camshaft adjuster (1) including a stator (2) and a rotor (4), a spring (6) tenses the rotor (4) rotationally counter to the stator (2). According to the invention, the spring is a coil spring (6), the stator (2) includes a first recess (8) of a first free end (10) of the coil spring (6) and the rotor (4) includes a second recess (12) for a second free end (14) of the coil spring (6).
