Abstract: A scarifier assembly for connection to a vehicle, including right and left first and second pivots. The scarifier assembly has a pivotal arm assembly having a rear cross member extending between and connected to forward extending right and left ends. The forward extending right and left ends are pivotally connected to the respective right and left first pivots. A plurality of teeth is connected to the rear cross member. A right lift actuator is pivotally connected to the right second pivot and pivotally connected to the forward extending right end of the pivotal arm assembly, and a left lift actuator is pivotally connected to the left second pivot and pivotally connected to the forward extending left end of the pivotal arm assembly.

Abstract: A bow stabilizer assembly for stabilizing an archery bow having a hand grip on a riser portion of the bow, the bow stabilizer assembly including a rod having a proximal end and a distal end. The proximal end of the rod connects to the riser portion at a location spaced above the hand grip. The bow stabilizer assembly further includes a bow stick mounting assembly comprising a bracket rotatably connected to the rod, a pivot connected to the bracket and extending below and perpendicular to the rod, and a coupling connected to the pivot and having a distal end that is movable toward and away from the bow. A bow stick assembly may be connected to the coupling to use in combination with the bow stabilizer assembly.

Abstract: A grading system for connection to a vehicle having vertically movable arms, the grading system including a grading blade assembly having a frame having a first pivot extending upward, a second pivot extending forward, a blade connected to the frame via the first pivot and the second pivot, a blade yaw actuator and a blade roll actuator, wherein the frame is configured to have the first pivot extend substantially vertically and the second pivot extend substantially longitudinally when the grading blade assembly is connected to the vehicle and the blade and vehicle are in a level position on a ground surface and the vertically movable arms of the vehicle are in a first raised position above a lowest most position.

Abstract: A system for updating firmware comprises an interface and a firmware update determiner. The interface is for receiving a firmware update bundle, wherein the firmware update bundle comprises a pre-instruction and one or more firmware updates, and for receiving configuration information describing a network cluster. The firmware update determiner is for determining an indication to update a set of nodes of the cluster based at least in part on the configuration information, wherein the indication includes the pre-instruction(s) and the one or more firmware updates. The interface is further for providing the indication to update the set of nodes of the cluster and receiving a summary from each node of the set of nodes of the cluster.

Abstract: A dozer blade assembly for connection to a vehicle having a vertically movable mount, the dozer blade assembly including a blade connected to a blade support frame by a universal joint, and being pivotally movable relative to the blade support frame about a vertical yaw axis so as to turn left or right, about a lateral pitch axis so as to rotate forward or rearward, and about a longitudinal roll axis so as to tilt left or right. The dozer blade assembly further includes at least one yaw actuator, at least one pitch actuator and at least one roll actuator, with the actuators connected to the blade and to the blade support frame in locations that permit compound movements of the blade relative to the blade support frame.

Abstract: A scarifier assembly for connection to a vehicle, including right and left housing assemblies, each of which includes a first and second pivots. The scarifier assembly has a pivotal arm assembly having a rear cross member with a forward extending right end connected to the first pivot of the right housing assembly and a forward extending left end connected to the first pivot of the left housing assembly. A plurality of elongate teeth are removably connected to a plurality of flanges that are connected to the rear cross member. A right lift actuator is pivotally connected to the second pivot of the right housing assembly and pivotally connected to the forward extending right end of the pivotal arm assembly, and a left lift actuator is pivotally connected to the second pivot of the left housing assembly and pivotally connected to the forward extending left end of the pivotal arm assembly.
