Abstract: A wireless hoist system including a first hoist device having a first motor and a first wireless transceiver and a second hoist device having a second motor and a second wireless transceiver. The wireless hoist system includes a controller in wireless communication with the first wireless transceiver and the second wireless. The controller is configured to receive a user input and determine a first operation parameter and a second operation parameter based on the user input. The controller is also configured to provide, wirelessly, a first control signal indicative of the first operation parameter to the first hoist device and provide, wirelessly, a second control signal indicative of the second operation parameter to the second hoist device. The first hoist device operates based on the first control signal and the second hoist device operates based on the second control signal.

Abstract: A system, device and method to facilitate tying a knot are provided. In the context of a device, the device includes a fixture defining an internal passage therethrough. The fixture defines a circumferential groove opening through an interior surface of the fixture and into the internal passage. The groove includes first and second groove portions that cross one another. Opposite ends of the groove are coincident and open through an exterior surface of the fixture. With relation to a system, the system includes a fixture and a lead member supply mechanism configured to alternately feed a lead member through the groove and to withdraw the lead member from the groove once the tie member is connected thereto.

Abstract: A powered fastener driver includes a driver unit, a handle unit, and a handle extension. The handle unit is selectively and removably attachable to the driver unit. The handle extension has a first end and a second end, the handle extension being selectively and removably attachable to the driver unit at the first end, and being selectively and removably attachable to the handle unit at the second end. The powered fastener driver is adjustable between a first configuration in which the handle unit is directly attached to the driver unit, and a second configuration in which the driver unit is attached to the handle extension at the first end, and the handle unit is attached to the handle extension at the second end.

Abstract: A zero-gravity hoist system including a chain fall, a motor coupled to the chain fall and configured to drive the chain fall in one or more directions, a power supply configured to provide power to the motor, and a controller having one or more electronic processors. The one or more electronic processors are configured to measure a first force of a load in response to receiving an input, store the measured first force in a memory of the controller, measure a second force of the load, determine a difference between the second measured force and the first measured force, and adjust a height of the load based on determining that the second force differs from the first force by a predetermined threshold.

Abstract: There are provided herein methods and products resulting therefrom. The methods include attaching a pre-fabricated porous ingrowth structure to a substrate by applying heat, or creating and bonding an in-situ-formed porous ingrowth structure from beads on a substrate by applying heat. In some embodiments, an oxidized metal surface of the substrate is diffusion hardened during the heating process. In some embodiments, a vacuum is applied during the heating process. In some embodiments, pressure is applied during the heating process. Also provided herein are assemblies for compressing the pre-fabricated porous ingrowth structure or the beads onto the substrate during the heating process.
