    摘要： A buckle includes a tab having a first side opposed to a second side and a receiver having a first side opposed to a second side. A first pair of pawls is pivotally connected to the first side of the tab. A cavity is defined in the receiver between the first and second sides of the receiver and configured to receive the first and second sides of the tab. The first pair of pawls has a locked position in which the first pair of pawls is engaged with the receiver to prevent movement of the tab with respect to the receiver and a released position in which the first pair of pawls permits movement of the tab with respect to the receiver. A first button on the first side of the receiver has a released position that moves the first pair of pawls to the released position.

    摘要： An anti-ram system and method of construction having a shallow mounted base pad from which extend a plurality of bollards. Very little or only a shallow excavation is required for the base of the bollard system, which can be partially or fully assembled prior to bringing it to the installation site. The shallow mounting pad or base of the bollard system of this invention may be formed or constructed in various ways and of various materials, and in various configurations. The shallow mounting pad or base is constructed so as to have considerable mass.

    摘要： A method of operating a gaseous-fueled internal combustion engine comprises selecting one of at least two predetermined operating modes as a function of engine load and engine speed. A first operating mode is selected when said engine is commanded to operate within a first region corresponding to a low load and low speed range, and a second operating mode is selected when said engine is commanded to operate within a second region distinct from said first region and corresponding to at least one of a greater load and a greater speed range compared to said first region. In the first operating mode, the gaseous fuel is introduced in a single injection event with the injection valve commanded to open with a constant amplitude A1. In the second operating mode, the gaseous fuel is introduced in a single injection event and the injection valve is commanded to begin with a constant amplitude A2 for a predetermined time and then to open to an amplitude A3, wherein amplitude A3 is greater than amplitude A2.
