    Abstract: A security system for a floating structure such as a boat, or the like, and which comprises an electro-mechanical apparatus that is sensitive to substantial changes in the position or orientation of the floating structure. A sensor circuit means is employed for sensing unanticipated changes of conditions of the floating structure. A detector circuit means is operatively connected to said sensor circuit means to detect loss of continuity in said sensor circuit means. An alarm means is operated by the detector circuit means. A power supply means, preferably a 12-volt lead-acid storage battery, is connected to the sensor circuit means, the detector means and the alarm means, to provide operating energy for said sensor and detector circuit means and alarm means.

    Abstract: A system and method for providing increased traffic carrying capacity of a road, such as a highway, by modifying an existing roadway from, for example, four lanes to five lanes, to create an additional travel lane. The system and method dynamically changes the width of travel lanes using, for example, embedded pavement lights, or other lighting arrangements, in lieu of traditional painted lane lines. As traffic volumes increase and speeds decrease along the road, an intelligent transport system (ITS) sends a congestion signal to the overhead lane controls and dynamic message signs (DMS) along the entire road segment of interest. The posted speed limits are changed, and the lane markings are controlled to dynamically increase the number of lanes in the road segment to five, for example, of narrower widths until traffic volumes reduce and the number of lanes can be returned to four, for example, with normal speed limits.
