The control device can be configured to determine a control value based on a commanded travel speed for the power machine and a pressure in the hydraulic circuit, and control a run-time displacement of the hydraulic motor based upon the determined control value.

Abstract: A stringer connector for rigidly connecting staircase stringers together. The stringer connector is a channel having a base with tabs extending inward from the base for physically locating the stringers in the channel. Openings are formed through walls of the channel for insertion of fasteners through the stringers. A base surface of the channel preferably further comprises a plurality of ridges extending inwards from respective ends of the channel to separate the stringers from the base surface, the base preferably further comprises a bracket for attaching the stringer connector to an intermediate support structure. A staircase constructed using the stringer connector is also included.

Abstract: Force-based control for electrically actuated power machines. One system may include one or more electronic processors in electrical communication with an electric actuator of the electric power machine. The one or more electronic processors may be configured to receive data for an electric power machine while the electric power machine is performing an operation and determine, based on the data, a force of the electric power machine. The one or more electronic processors may be configured to, responsive to the force exceeding a threshold, control the electric power machine to enforce a force limit.

Abstract: Port-relief emulation for electrically actuated power machines. One system may include one or more electronic processors in electrical communication with an electric actuator of the electric power machine. The one or more electronic processors may be configured to receive data for an electric power machine while the electric power machine is performing an operation and determine, based on the data, a force on an electric actuator of the electric power machine. The one or more electronic processors may be configured to, responsive to the force exceeding a threshold, control the electric actuator or another electric actuator of the electric power machine to enforce a force limit.

Abstract: A glass fencing system includes glass panels, rails, gaskets, and spigots. The rails extend across the upper edges of the glass panels. The gaskets are fitted within the rails. The spigots support one of the glass panels and comprise a base, a first arm, a first pad, a second arm, and a second pad. The first pad has a first pad surface and a lower surface. The first pad surface is in contact with the first arm and the glass panel. The lower surface extends from the first pad surface and is in contact with the glass panels. The second arm has bores. The second pad has a second pad surface, a backing, a plate, and fasteners. The second pad surface is in contact with the glass panel. The backing is spaced apart from the second pad surface and has backing openings aligned with the bores. The plate is located between the second pad surface and the backing. The fasteners pass through the bores and the backing openings to contact the plate.
