Abstract: Surrogates for roadside objects, such as concrete curbs, can be used for vehicle testing. A surrogate for a concrete curb can substantially be similar in size and/or shape as the concrete curb that the surrogate is mimicking. The surrogate can be configured to exhibit substantially the same characteristics as their actual counterpart concrete curb when sensed by one or more vehicle sensors (e.g., cameras, radar sensors, and/or LIDAR sensors). Such surrogates can be used to test automated vehicles, one or more vehicle sensors, a vehicle sensor system, and/or one or more vehicle system (e.g., a road departure mitigation system). The surrogates can be configured to withstand being impacted by a test vehicle without being damaged and without damaging the test vehicle.

Abstract: A wear member for earth working equipment and a wear assembly including a plurality of such wear members. The wear member defines a longitudinal axis and comprises: a body defining a rearward opening cavity dimensioned to receive a base; first and second lateral portions extending from opposing sides of the body and defining a front edge for engaging earth. The first lateral portion defines a complementary formation to the second lateral formation to enable axial insertion and removal of a wear member mounted between adjacent wear members due to the open removal path defined by the complementary formations. The complementary formations also resist rotational movement of the wear member about the longitudinal axis.

Abstract: A snow and ice evaporating device that is an untethered device easily usable by an individual. The device has elements that resemble a traditional snow blower as well as a lawn mower, but that includes a salt hopper and a propane tank. The snow blower end operates much like a traditional snow blower with augers that break up snow and ice that are then expelled through a blower end. On the top of the device is a propane tank that provides flames to the bottom of the device, protected by a shroud that heat the surface being treated to melt both ice and snow. A salt hopper is situated on the back of the device which provides a means for applying salt to the treated surface to prevent refreezing. All portions of the device are easily controlled by and extended handle that the user uses to control these functions. The extended handle operates much like a lawn mower in that it allows the user to easily push the device which rolls on wheels and includes a kill switch to turn off the device in an emergency situation.
