Abstract: A highback is provided for controlling a gliding board, such as a snowboard, through leg movement of a rider. The highback is comprised of an upright support member to support a rear region of the rider's leg. The highback includes a textile-like material that extends across a portion of the support member to provide support for a portion of the rider's leg. The support member may have an opening therein with the textile-like material extending across the opening to assist in transmitting forces applied to that region of the support member as the rider presses against the highback during riding maneuvers. The textile-like material may help to distribute forces across a larger area of the rider's leg or boot so as to reduce pressure points against the rider's leg. The textile-like material may include one or more filaments, a fabric, or a fabric-like material that is coupled to the support member to support the rider's leg. The textile-like material may include a mesh fabric.

Abstract: Data is collected and interpreted in response to one or more transmitted signals to determine if an interfering device is present. If an interfering device is present, a message is generated and presented to a user indicating, for example, that the installation of a micro-filter is appropriate. The system can then determine if the micro-filter was installed properly and, for example, commence communication or, if the micro-filter(s) did not solve the problem, initiate communication with or contact a technician.

Abstract: A method and apparatus for providing a gliding board binding, such as a snowboard binding. The binding may include an adjustment indicator that allows for determination of a longitudinal position of the base relative to a gliding board, heel-to-toe position of the base relative to a gliding board and/or an angular position of the base relative to a gliding board when the base is secured to the gliding board. The adjustment indicator may be included with a footbed that is removable from a binding base, e.g., that includes a foot engagement member to secure a rider's foot to the binding and board. A removable footbed may include a toe portion that is adjustable in position relative to a heel portion of the footbed. A gliding board may include a channel for mounting a binding that is arranged in the board core so that no portion of the board core is located on top or bottom sides of the channel, and instead so the top and bottom reinforcement layers are located above and below the channel.

Abstract: A three-port TDR front end comprises numerous components. An exemplary three-port TDR front end is a DSL modem. Information-bearing TDR signals are distorted as they pass through these components. With a perfect model of the response of its front-end, a TDR system usually can compensate for the effects of its front-end. In reality, however, the electrical characteristics of each component vary from design-to-design, board-to-board, and slowly over time The result is imperfect knowledge about the true response of the front-end, errors in the model of the front-end, and degraded TDR performance. At least for this reason it is important to precisely calibrate the response of the TDR front-end through the use of a TDR modeling system.

It is important to calibrate the response of the TDR front-end through using a TDR modeling system that determines at least three respective responses when the third port is connected to each of at least three different devices, determining three parameters that characterize a front-end, and using the three parameters to predict the system response when the front-end is connected to any device.

Abstract: A remotely-operated unmanned vehicle attached to the hull of a marine vessel by electromagnets surveys the hull for damage. The vehicle attached to the hull is electronically controlled from a remote location. An imaging system on the vehicle provides an operator with images of the vessel's hull and the surrounding environment. Once damage has been found and assessed, the vehicle applies a patch over the damaged opening in the hull to prevent cargo outflow and water inflow. The patch, which resists puncturing and tearing, is constructed from one or more sheets of flexible material having dimensions appropriate to cover most openings.
