A truck bed cargo barrier for use with a truck bed for stabilizing cargo items longitudinally and laterally. The cargo barrier is slidable relative to the front and back of the truck bed along a track system. The cargo barrier may be locked in a user specified position along the track system to accommodate the size of the load being carried forming a divider, or may be flipped up into a temporary storage position for linear cargo exceeding the length of the bed. Tie down brackets for bungee cords are adjustably attached to the barrier frame to secure cargo laterally. A barrier panel is connected to laterally adjustable, rigid side plates, each including two spaced apart wheels that ride on a pair of longitudinal tracks on the side walls of the truck bed. The spaced apart wheels firmly secure the barrier panel in a vertical position. A manual actuator permits manual positioning of the barrier panel along the bed frame front to back.

The invention relates to a vehicle-mounted inertial navigation system. According to the system, GPS / DR / MM technologies are combined for vehicle-mounted inertial navigation, vehicle speed pulse signals do not need to be collected, information is directly read through a CAN bus of a vehicle sound port, and vehicle refitting is avoided. The system comprises a main processor MCU, a gyroscope, a GPS and a map, dynamic compensation is adopted for gyroscope zero offset errors, an HDR algorithm is adopted for random drift errors for compensation, the system does not only depend on data basis that inertial navigation is achieved by reading vehicle body information, GPS positioning information and DR system positioning information are further corrected through the map matching technology, and therefore overall vehicle safety and navigation positioning reliability are improved.

The present invention relates to a bullet. More particularly, the present invention relates to a bullet including concentric and sequentially ordered cylindrical fore, intermediate and aft portions. The aft portion comprises a cross-sectional diameter about equal to the diameter measured across the rifle landings of the riffled barrel operatively to create a gas pressure build up there-behind while the rifling grooves and lands deform and / or cut the aft portion thereby to impart spin to the bullet about the central axial axis thereof. The intermediate portion comprises a cross-sectional diameter smaller than that of the aft portion, which acts as a bearing surface for operatively riding along the rifling lands thereby to inhibit yawing of the bullet while operatively travelling through the rifled barrel. The fore portion comprises a cross-sectional diameter smaller than that of the intermediate portion with an annular stamping surface, for operatively providing a clean cut circular hunting wound, located at or near an interface between the fore and intermediate portions.

A tracked vehicle for preparing a ski track is provided. A tracked vehicle (1) comprises: a frame (2); a winch (12) mounted on the frame (2) for selectively deploying and winding a rope (13) that can be anchored to a point (14) outside the tracked vehicle (1); an arm (16) mounted to rotate relative to the frame (2) about a defined axis (A2) and configured to guide the rope (13); an actuation system (17) of the arm (16) around a defined axis (A2); control means (18) of an actuation system (17) of the arm (16) for selectively setting, when the rope (13) is under tension, one of the following operating modes: allowing the arm (16) to rotate freely about a determined axis (A2); rotating the arm (16) about a defined axis (A2); the position of the arm (16) relative to the frame (2) is locked.

The present invention relates to the field of floor treatment machines for scrubbing, polishing, sanding or burnishing floors, and in particular machines in which one or more driven rotatable work heads (such as scrubbing brushes) are provided for agitating the floor surface. In one aspect there is provided a walk-behind floor treatment machine comprising: a base portion provided with and supported by at least one rotatable work head for treating the floor, a handle portion for steering or guiding the machine along a working direction of travel and adapted to be pivotable with respect to the base portion, drive means for rotating the work head with respect to the base portion, floor-engaging wheel means for supporting the handle portion, the wheel means having a substantially transverse axis of rotation so as to permit travel in the working direction, the wheel means being coupled to the base portion by a linkage which permits vertical travel of the base portion and associated work head or heads with respect to the wheel means, but which provides transverse constraint to limit or prevent yawing of the base portion with respect to the wheel means, wherein a lower region of the handle portion is pivotably connected to the wheel means via an articulated joint, the arrangement being such that the handle portion may be manipulated to act on the wheel means so as to yaw steer the wheel means about a yaw axis defined by the floor-engaging contact of the wheel means, the yawing of the wheel means causing the base portion to yaw in response to yaw steering. The wheel means may comprise a wheel, roller or ball, preferably a single wheel, roller or ball, disposed at a lower region of the handle portion. The wheel means preferably has a fixed transverse axis of rotation.

The embodiment of the invention discloses a voice navigation method, electronic equipment and a computer program product. The method comprises the following steps: acquiring a navigation route and voice navigation content; the voice navigation content comprises voice content and voice broadcast time; broadcasting the voice content on the basis of the voice broadcasting opportunity in the driving process of the navigated object on the basis of the navigation route; and after the voice content is broadcasted, dynamically adjusting the voice content of the next voice broadcasting time based on the behavior feedback information of the navigated object. According to the technical scheme, the problem that the user is likely to yaw when the existing fixed voice broadcasting time and the fixed voice content are adopted under the condition that the user is inattention in the driving process can be avoided, the yaw rate of the user can be reduced, and the navigation experience of the user is improved.
